+
+ CHAPTER I
+
+ THE WOMAN IN THE LIMOUSINE
+
+
+Standing in the dark doorway of a delicatessen shop, Kingdon Cole
+gazed, through the fog and drizzle of the October night, at a
+second-story window across the street. The brim of a slouch hat
+shaded his eyes and most of his face. His lean figure was draped in a
+mackintosh that reached almost to his feet. The upward slant of the
+cigar, clamped between his teeth, hinted at total absorption in what he
+saw.
+
+The building that claimed his attention was an ordinary three-story
+structure of murky brick. Flanked by a warehouse on one side and a
+secondhand clothing store on the other, it presented a sullen and
+gloomy aspect to the watcher across the street. Yet there was something
+in the very drabness of the house and the chill atmosphere which hung
+over it that might have appealed to the imagination of a man like
+Kingdon Cole.
+
+A man’s head and shoulders were dimly silhouetted against the lighted
+window shade at which he was looking so fixedly. For half an hour or
+longer the figure had not stirred. The rigid poise of the head and the
+stiff set of the shoulders suggested that the man at the window was
+engaged in a task that occupied his whole mind.
+
+Cole struck a match and, holding it in his cupped hands, lighted his
+dead cigar. The flickering light shone for an instant on fingers that
+were long, slim, and finely tapering, the fingers of a man of great
+mental energy and a compelling personality.
+
+“Wonder what the learned Professor Carmody finds so interesting,” he
+mumbled. “Some scientific treatise, very likely, or perhaps it is——”
+
+He lowered his gaze, as he vaguely sensed that a pair of eyes was
+trying to pierce the gloom in which he stood. What with the wet night
+and the lateness of the hour that dreary section of Bleecker Street
+was all but deserted. Now and then a crosstown car jogged along at a
+lumbering pace; occasionally a taxicab passed on its way.
+
+Cole looked up and down the block. The impression was more distinct
+now. Some one was watching him, just as he was watching the solitary
+figure in the window. His senses, sharpened by long training, told him
+he was under observation even before he could trace the impression to
+its source. Now he saw a limousine drawn up at the corner, less than
+twenty paces from where he stood. Its sides of burnt sienna gleamed
+in the blurred lights. It seemed to lend a touch of affluence to the
+squalor and dreariness of the scene. How long the car had been there
+he did not know, for the window across the street had claimed all his
+attention.
+
+The car began to move, crawling, snaillike and silent toward the point
+where Cole stood. It stopped opposite the doorway that sheltered him.
+He fancied that he saw the flicker of a face behind the curtains. Then
+the door opened a few inches, and he caught a glimpse of a beckoning
+hand.
+
+His eyes narrowed under their puckering brows. The monotony of his
+vigil was being broken in a strange way, and the slow twisting of his
+lips signified that the interruption was not altogether displeasing.
+Once more he glanced up at the window across the street, noticing that
+the shadowy figure had not stirred. Then he crossed the sidewalk, and
+instantly the door of the limousine was flung wide.
+
+“Won’t you step in, Mr. Cole?” asked a voice.
+
+Though his life had inured him to surprises, Cole started a little. It
+was odd that the occupant of the car should address him by name. The
+interior was dark, but in the shadows he saw the figure of a woman.
+
+“You are very patient, Mr. Cole,” the voice continued. “You are wasting
+your time, however. It isn’t likely that Professor Carmody will go out
+to-night, so you might as well jump in.”
+
+A sharp hunching of Cole’s shoulders registered surprise number two. It
+was all very mystifying. Not only did the occupant of the car know his
+name, but she seemed familiar with his business as well. He liked her
+voice, a deep soprano with a faintly playful undertone. For a moment he
+studied the long, slender lines of her figure, faintly discernible in
+the dusk and melting, here and there, into a background of saffron-hued
+cushions.
+
+“You hesitate? I happen to know that Professor Carmody is in for the
+night and that your vigilance is useless.”
+
+Cole looked at her intently. The mist, the drizzle, and the blurred
+sheen from the street lamps seemed to lend a touch of unreality to
+what he saw and heard.
+
+“What do you know about Professor Carmody,” he demanded.
+
+“A great deal more than you do. It’s quite possible that I am in a
+position to give you some valuable information. At any rate my car is
+more comfortable than a dark doorway.”
+
+She leaned forward slightly, and there was a trace of mockery on her
+faintly parted lips. “Not afraid, are you, Mr. Cole?”
+
+He gave a low laugh at the implied dare. With a shrug he stepped inside
+the car and sat down beside her. She picked up the speaking tube and,
+turning her head away from Cole, said something which he could not
+hear. In an instant the car was in motion.
+
+“You seem to know a great deal,” he observed, trying to obtain a
+glimpse of her face under the billowing brim that shaded it.
+
+“And you are anxious to learn how much more I know. Isn’t it so, Mr.
+Cole? It was neither vulgar curiosity nor adventurousness that prompted
+you to accept my invitation to ride with me. You accepted only because
+you hoped to learn something. Having heard me speak your name and
+mention Professor Carmody you naturally thought it might be profitable
+to cultivate my acquaintance.”
+
+“Perhaps so,” said Cole dryly. “What do you know about me aside from my
+name and my interest in the estimable professor?”
+
+“A great deal,” was the surprisingly prompt reply. “You are a student
+of criminology, a follower in the footsteps of Lombroso, Pinel, and
+Prichard, though you by no means accept their theories. You have
+written two books on crime and criminals. They are too scientific for
+the general reader, I have been told, but experts on the subject regard
+them as authoritative. Perhaps some day I shall try to read them.”
+
+“I fear you won’t find them very interesting,” replied Cole. “What
+else?”
+
+“You live in a small apartment in Gramercy Park, which also serves as
+your office. Two years ago you did a very brilliant piece of work on
+the Wilmerding murder case, though you magnanimously, or for reasons of
+your own, let the police claim the credit for the results. You follow
+criminal investigations largely as a scientific pursuit. If you cared
+to devote all your time to it you could make a great success, but you
+accept only such cases as happen to interest you personally. As a
+result you lead a quiet and somewhat precarious existence, deriving
+your sole pleasure from your work and such inexpensive amusements as
+books, music, and, on rare occasions, the theater.”
+
+“You seem to have taken considerable pains looking me up,” he remarked.
+
+“Oh, I haven’t told you all I know yet. I have learned a number of
+things about your private life and personal habits, but we needn’t go
+into those things now.”
+
+“Are you equally well informed in regard to Professor Carmody?”
+
+“Not quite. The professor is a riddle. To all outward appearances he is
+interested in nothing but his experiments and his musty old books. He
+seems to be living in that kind of neighborhood by preference, because
+he isn’t so apt to be bothered by meddling neighbors. His house is said
+to contain one of the best-equipped laboratories of its kind in the
+world. That’s only a rumor, of course. The professor doesn’t encourage
+visitors. To the few people who have talked with him he is what the
+novelists call a man of mystery. He comes and goes without speaking
+to any one, and his life is a closed book. As far as I know, only one
+person has been inside his house in a year, and that person never came
+out.”
+
+“Oh, you know that!”
+
+“Yes, I am one of the very few who are aware of the fact. Let me see,
+it’s about three weeks since Malcolm Reeves disappeared. His relatives,
+your clients, in other words, have reason to believe that he visited
+Professor Carmody on the night of his disappearance. No wonder the
+case fascinates you, Mr. Cole. Disappearances are always interesting,
+but especially so when a mysterious person like Professor Carmody is
+involved.”
+
+Cole regarded her in frank amazement, but her head was now slightly
+bowed, and all he could see of her face was the curve of the chin.
+
+“The relatives did well to put the case in your hands,” she went on.
+“You are both capable and discreet and, as I presume you know, there
+were excellent reasons for not reporting Reeves’ disappearance to the
+police. Are you making satisfactory progress?”
+
+“My clients seem satisfied.”
+
+“You have not yet paid the professor a visit?”
+
+“What would be the use?”
+
+“You are right, of course. It would only put him on his guard. You
+prefer not to let him know that he is under suspicion.” She laughed
+gently, as if amused at something. “Besides, it is doubtful whether a
+search of Carmody’s house would reveal any clews to Reeves’ fate. The
+professor is a chemist, and I understand there are certain chemical
+processes by which bodies can be made to disappear completely, leaving
+no trace.”
+
+“Then you think Reeves has been murdered?”
+
+“Don’t you?” she asked quickly.
+
+Cole smiled. Instead of answering the question he asked another. “How
+can you be so sure that Carmody will not leave his house to-night?”
+
+“Because he has the best of reasons for staying in.”
+
+“What are they?”
+
+“One is that his engagement for to-night was canceled by telephone at
+four o’clock this afternoon.”
+
+Cole gave her a puzzled stare. “How do you know that?”
+
+She laughed a little. “There are ways of finding out,” she said
+mysteriously. “Tapped wires, for instance. But the professor’s
+principal reason for staying in to-night is that he is well aware that
+you are watching him. You see, Mr. Cole, he has more shrewdness than
+you have been giving him credit for. And the fact that he is staying in
+on your account shows that he has great respect for your ability.”
+
+She had raised her head a trifle, and Cole gave her a long, bewildered
+glance. He half expected to see a smile on her lips, but her face was
+grave.
+
+“Are you one of Reeves’ relatives?” he asked abruptly.
+
+“Oh, no!”
+
+“Then how——”
+
+“I have certain sources of information. Sources so vast that you would
+be staggered if I were to tell you of them. Please don’t look at me
+like that. I am not insane, neither am I subject to hallucinations. The
+fact that I happen to know more about the Carmody case than you do is
+no reflection on your ability as an investigator. It merely shows that
+your equipment is inadequate. Care to hear more?”
+
+“What else do you know?”
+
+“I know that the case you are working on is only one minor angle of a
+vast mystery. The disappearance of Malcolm Reeves is nothing but an
+incident. Reeves himself was only an insignificant puppet in one of
+the greatest games ever played. All you have seen so far is one of the
+minor threads in the woof. I am always mixing my metaphors, but I know
+you won’t mind. Mr. Cole, this affair has ramifications that may some
+day rock the whole continent.”
+
+“I feel considerably shaken up already,” admitted Cole. “You realize,
+of course, that you are using strong words?”
+
+“No stronger than the situation demands.”
+
+“If it is as bad as all that why doesn’t somebody put a stop to it?”
+
+“Because——” She checked herself and regarded him intently. “Well,
+because the man who is big enough for the task has not yet been found.”
+
+Again Cole cast a glance at the window. The car had made several
+turns in the last few minutes. He caught only a blurred view of his
+surroundings, but he thought they were traversing one of the cavernlike
+streets near the southern tip of Manhattan Island.
+
+“Have you heard enough?” she asked.
+
+“Just enough to give me an appetite for more.”
+
+“In that case you must trust me implicitly and obey me without
+questions. I am taking desperate chances in confiding in you, Mr. Cole,
+and certain precautions are absolutely necessary. Will you promise me
+on your honor that you will not try to ascertain the location of the
+place I shall take you to?”
+
+Cole considered. There was a flavor of mystery about the adventure that
+appealed to him, but the prospect of learning something more about the
+Carmody case was an even greater temptation. From what little the woman
+had so far told him he surmised that she must have unusual sources of
+information. Much that she had said coincided with what he already
+knew, so he had no cause to doubt her truthfulness.
+
+“You have my promise,” he told her.
+
+The car made another turn, swung down a dark block, then veered again
+to the south. Cole caught a hazy glimpse of dark, towering skyscrapers.
+
+The woman looked at him fixedly, as if in doubt. “I believe you are a
+man of your word, Mr. Cole, but promises are sometimes broken in spite
+of the best intentions. Please don’t be offended.”
+
+She produced a scarf and with a deft touch covered his eyes, securing
+the bandage with a firm knot at the back. Cole chuckled amusedly. He
+might be walking into a trap, but it would not be the first time, and
+he had great confidence in his ability to take care of himself in any
+situation that might come up.
+
+After continuing its zigzagging course a few minutes longer the car
+stopped. His mysterious conductress touched his arm as they stepped
+out. She guided him across the sidewalk and up a few stone steps, and
+then they traversed what appeared to be a long corridor. Finally Cole
+found himself in a narrow inclosure which he guessed to be an elevator.
+
+“We are in one of the tallest office buildings in New York,” the woman
+whispered in his ear, “but you’re not likely to guess its name.”
+
+The door clanked shut, and the cage shot swiftly upward. Cole felt
+a rush of wind in his ears. He maintained a languid composure, but
+inwardly he marveled. A modern skyscraper was the last place he would
+have expected the woman to take him to. He tried to estimate the number
+of floors they were passing. Five, ten, fifteen, twenty——
+
+Still the cage darted upward, and then it stopped so suddenly that
+he caught his breath sharply. They stepped out, and the girl removed
+the scarf from his eyes. He gazed around him bewilderedly. All about
+him, with the exception of a single elevator shaft was a vast expanse
+of blank wall. There was no sign of doors or windows, and the only
+illumination was a small electric bulb in the ceiling.
+
+“We came up in a private elevator,” the woman explained. “This is the
+top floor. To the public at large and to most of the tenants of the
+building it practically does not exist. This way, Mr. Cole.”
+
+She stepped to one of the corners of the triangular space, of which the
+elevator shaft formed the center, and Cole followed. In the dim light
+he could not see exactly what happened, but the woman’s hand went out
+and then a narrow portion of the wall slid back. They stepped through
+an aperture, and instantly the opening closed behind them. They were in
+a long corridor with doors on each side.
+
+“Surprised?” she asked, starting to lead him down the hall.
+
+“Rather. Never expected to find such mysterious contrivances in a
+modern office building.”
+
+Her only reply was a low laugh. The floor of the corridor was
+luxuriously carpeted; the doors on either side had a solid appearance.
+Cole’s amazement grew. He wondered what was beyond the massive doors
+and what was the nature of this establishment that was hidden behind
+blank walls. He had little time for speculation, for his companion
+opened a door and bade him enter.
+
+“Excuse me, Mr. Cole,” she murmured when she had switched on the light.
+“I shall be back directly.”
+
+The door closed, and she was gone. Alone, Cole looked about him, and
+his eyes opened wide in astonishment.
+
+
+
+
+ CHAPTER II
+
+ TEMPTATION
+
+
+For a moment Cole forgot that he was in a building devoted to the
+pursuits of commerce. The room in which he stood, bordered by walls of
+paneled walnut, was worthy of a Fifth Avenue mansion. It struck him as
+a bit grotesque. From an elevator he had stepped, through a blank wall,
+into a magnificence that fairly dazzled him. It was like an “Arabian
+Nights” adventure. As he looked about him he saw quiet elegance
+everywhere, without a taint of showiness. For some time he stood lost
+in admiration, then he noticed that the room had no windows. A moment
+later he discovered that the door was locked on the outside. Despite
+the splendor that surrounded him he was virtually a prisoner.
+
+He sat down and smoked a cigarette, waiting for his strange conductress
+to return. Evidently the walls were solidly built, for no sounds
+reached him. The air was fresh and pure despite the absence of windows,
+hinting that there was a concealed ventilator somewhere in the room.
+
+The armchair was comfortable, and he stretched out his lean figure,
+slightly short of six feet. The man suggested mental force rather
+than bodily strength, but a great surprise awaited any antagonist who
+underestimated Cole’s physical prowess. He was far stronger than the
+average man, and his endurance was phenomenal. His gray eyes, with a
+faint humorous twinkle in their depths, were fixed on the door. His
+dark face, slightly lined about the mouth and the outer corner of the
+eyes, bore a look of mild expectancy. In moments of repose he looked as
+though he had not a care in the world. His friends often wondered how
+he managed to maintain the freshness and sparkle suggestive of a recent
+needle shower. Perhaps it was because he was thoroughly in love with
+his work and had learned to shake off the minor frets and irritations
+of life.
+
+In the midst of his musings the door opened, and he stared rather
+rudely at the vision that entered. It was the woman, and she had
+undergone an amazing transformation since he last saw her. He wondered
+whether the shimmering gown she wore had been designed by Poiret
+himself. Its delicate rose color afforded a charming contrast to her
+complexion, a sort of luminous white that somehow escaped being pale.
+Standing there, with a faint smile on her lips, her face fringed by an
+aureole of fine-spun gold, she was easily the most bewitching woman
+Cole had ever seen.
+
+He rose, bowed, and gazed appreciatively at the simple, but strikingly
+effective, ornament she wore at her throat.
+
+“Sorry to have kept you waiting,” she murmured. “Sit down, please, and
+smoke as much as you like. I want to talk with you.”
+
+Cole sat down. He wondered if she had arrayed herself like this for the
+sole purpose of having a talk with him.
+
+“You promised to tell me something more about the Carmody case,” he
+reminded her. “I suppose you brought me to this charming place so
+that we might have a quiet talk without danger of interruption or
+eavesdropping.”
+
+She sat down a short distance from him. By degrees the smile faded from
+her lips. A curiously solemn expression crept into her face. “Haven’t I
+told you enough, Mr. Cole?”
+
+“What little you told me was only a provocation. It gave me a taste for
+more. By the way, you have the advantage over me. Won’t you tell me
+your name?”
+
+“You may call me Miss Brown.”
+
+“The name doesn’t fit you,” he objected.
+
+“Names never do fit. That’s one of the ironies of existence. For the
+present, until we know each other better, it will have to be Miss
+Brown. I had to tell you a little about the Carmody case in order to
+get your attention. I hope I convinced you that it is quite useless
+for you to continue at work on a case that is so enormous in scope and
+presents such insuperable difficulties, Mr. Cole.” A pleading note had
+come into her voice. “Can anything persuade you to drop the Carmody
+case?”
+
+She bent forward a little. With hands clasped across her knee, she
+studied him intently, and Cole looked into the deepest, bluest eyes he
+had ever seen.
+
+“Drop the Carmody case!” he exclaimed.
+
+“You must drop it, Mr. Cole! If you knew more about it, what terrible
+things you are going up against, you would willingly drop it without
+further argument. You would recognize your utter helplessness in the
+matter, not to mention a number of other things.”
+
+Cole was momentarily speechless. He found himself strangely impressed
+by her big, sorcerous eyes, full of mute pleading and entreaty.
+
+“I don’t understand. You don’t realize what you are saying. Why should
+I drop the case?”
+
+“Because of the things I have told you.”
+
+Cole laughed. “They are only an added incentive for me to go on with
+it.”
+
+She drew a long breath. “That’s your man’s way of looking at things.
+The greater the dangers and difficulties the more determined you are
+to forge ahead. You don’t stop to consider the price, or estimate the
+cost. The wreckage you scatter about you means nothing to you. All you
+think of is the gratification of your boundless ambition. Mr. Cole,
+won’t you forgo your foolish pride and do what I ask?”
+
+Her eyes held him despite his will. There was a look of terror in
+their depths that exerted a subtle appeal upon him. He got to his feet
+and tried to shake off the fascination of her beauty and her magnetic
+personality.
+
+“Impossible,” he declared. “If you brought me here in the hope of
+inducing me to drop the Carmody case, your time and effort are wasted.”
+
+“Please, Mr. Cole! Forget that you ever heard of this terrible case.
+Tell your clients in the morning that you will have nothing further to
+do with it.”
+
+“That wouldn’t alter matters. They would promptly accept my
+resignation and engage somebody else.”
+
+“There is only one Kingdon Cole.”
+
+“That’s a very neat compliment, but it won’t bear analysis. I haven’t
+accomplished anything very wonderful, and another man could finish what
+I have begun.”
+
+She was silent for a time, her big, luminous eyes regarding him
+imploringly. “If you won’t drop the case for your own sake, because of
+the terrible dangers involved, then I beg you to do so for my sake.”
+
+“For your sake? Really, Miss—er—Brown, I don’t understand. What is your
+interest in the Carmody case?”
+
+She stepped up and clutched his hand. The touch of her fingers sent
+a thrill through him. Her eyes were moist, and the curve beneath her
+throat rose and fell with accelerated rhythm. “Yes, for my sake. I
+can’t explain, except to say that awful things will happen to me if you
+go on. Death would be as nothing in comparison. Doesn’t a woman’s soul
+mean anything to you, Mr. Cole?”
+
+Cole looked down into her eyes, while her fingers spasmodically
+clutched his hand. Far into their blue depths he gazed, and suddenly
+his face underwent a change. His lips curled a trifle, and a hard glint
+came into his eyes. Somewhat roughly he released his hand.
+
+“Very touching,” he dryly remarked, “but I don’t see the connection
+between the Carmody case and a woman’s soul.”
+
+She drew back with a little sob of bafflement.
+
+“If you meant your own soul, Miss Brown, you mentioned something that
+doesn’t exist,” he went on sarcastically. “Trickery and pretense are
+poor substitutes for soul.”
+
+“What do you mean?”
+
+He shrugged disgustedly. “Your acting is superb, but it don’t bear
+close inspection. You were splendid at a little distance. Despite the
+fact that I am the only Kingdon Cole, as you so charmingly phrased it,
+I am rather susceptible to the tears of a beautiful woman. With your
+sobs and your loveliness you could have melted a stone, if such a feat
+were possible. As soon as I got a close view of you, however, I knew
+you were only shamming. Your eyes gave you away when you sprung that
+choice line about a woman’s soul. Perhaps you realized you were laying
+the pathos on too thick. Anyway the illusion is shattered, and all that
+remains is the gorgeous gown you are wearing. It is really stunning.”
+
+“Thank you,” she said coldly, dropping the rôle she had been playing,
+as easily as she would a wrap. “No doubt I should have known better
+than to try such methods on you.”
+
+“Yes, you should,” said Cole. “For, despite the little slip you made,
+I believe that you are really a very clever woman. Now that we are off
+the subject of women’s souls won’t you tell me your real reason for
+wishing to throw up the Carmody case?”
+
+She shook her head, but he thought he detected a gleam of unwilling
+admiration in her eyes. Motioning him to follow, she stepped to the
+door and opened it, then preceded him down the hall. Cole guessed that
+his little adventure was over, and he felt a twinge of disappointment
+at the thought that, in all probability, he would never learn the
+meaning of her puzzling behavior. No doubt she would try to blindfold
+him again before conducting him away from the place, and he was
+prepared to raise strenuous objections.
+
+But it appeared Miss Brown was not yet ready to let him go. She stopped
+before one of the massive doors that had already excited his curiosity,
+and knocked twice. It opened quickly and noiselessly. In a moment,
+before he realized what he was doing, Cole was inside, and the door
+closed at his back.
+
+The room was so dimly lighted that at first he could distinguish
+nothing but bare, gloomy walls. Miss Brown, who had followed him into
+the room, hastened forward and seemed to melt away in the dusk, leaving
+him to wonder what new turn his adventure was taking. Gradually, as his
+eyes grew accustomed to the gloom, he was able to see objects with some
+degree of clearness. He was in a long, narrow room, and what he saw
+was in keeping with the other strange things that he had witnessed and
+experienced in this surprising establishment.
+
+A number of shadowy figures were seated around a circular table in
+the center of the room. He counted seven of them, and at first he had
+a ludicrous impression that there were only blank spaces where their
+faces should have been. Then, as his pupils continued to respond to the
+strain imposed by the dim light, he saw that each man wore a mask.
+It was only a strip of cloth, with tiny slits over the eyes, but in
+the dusk it was the only covering that was needed to make recognition
+impossible.
+
+Again Cole was struck with a sense of unreality. The men, sitting
+stiffly erect in their chairs, caused him to wonder whether he was in
+the midst of some ghostly séance. He felt their eyes searching him
+through the vents in the masks. The gloom and the silence gave an added
+illusory touch to the scene. Cole had to shake himself before he could
+realize that he was on the top floor of a modern skyscraper.
+
+Miss Brown stepped behind one of the chairs and held a brief whispered
+conversation with its occupant. The latter nodded, and the girl
+slipped away toward the door. A moment later it closed behind her, and
+the man, with whom she had been talking, indicated that Cole was to
+step forward. With a shrug he complied, and the masked faces stirred
+slightly as he approached. For a full minute nothing was said, and
+again he felt the sharp and steady scrutiny of seven pairs of eyes.
+Finally the man who had beckoned him spoke. “Mr. Cole, how much will
+you take to drop the Carmody case?”
+
+Cole could not help but laugh. The words, spoken with a directness
+and a matter-of-factness that left nothing to the imagination, had
+shattered the illusion completely. In an instant the spell of unreality
+was broken. He knew he was dealing with practical men who were in the
+habit of reducing everything to terms of dollars and cents. A blunt
+reply came to his lips, but his desire to learn more of these strange
+men caused him to hold it back.
+
+“Suppose we put all the cards on the table,” he suggested. “I don’t
+like to talk business in the dark. Who are you, and what is your
+objection to my connection with the Carmody case?”
+
+“We are not here to answer questions,” declared the one who seemed to
+be acting as spokesman for the others. “All I care to say is that,
+because of a peculiar combination of circumstances, it is to our
+advantage to pay you liberally for withdrawing from the case. What’s
+your price, Mr. Cole?”
+
+Under ordinary circumstances, Cole would have been indignant at this
+cool assumption that every man has his price, but now his dominant
+emotion was curiosity. He could not understand why they seemed so
+intent upon persuading him to sever his connection with the affair, but
+what Miss Brown had said about the vast ramifications of the Carmody
+case suggested that they had ample reasons for what they were doing.
+
+“Let me get this straight,” he said evenly. “You are willing to pay me
+my price for withdrawing from the Carmody case. Are there any strings
+to the proposition?”
+
+The other chuckled dryly. “I wouldn’t call them strings, exactly. They
+are only gossamer threads. In addition to retiring from the case you
+are to give us a full and veracious report of what you have discovered
+to date in connection with the disappearance of Malcolm Reeves.”
+
+“I see,” said Cole. “Anything else?”
+
+“Just one thing more. In addition to withdrawing from your present
+connection with the case and turning the information you possess over
+to us, you are to come over to our side and put your ability at our
+disposal. We are ready to pay you handsomely for your services, either
+on a contingent basis, or in the form of a weekly salary.”
+
+“Very generous,” declared Cole, with a faint trace of sarcasm. “Your
+proposition is that, for a consideration, I am to betray my present
+clients and——”
+
+“Betray is a harsh word,” objected the spokesman for the group.
+
+“Truthful terms are usually harsh,” Cole remarked. “Let’s not quibble
+over words. In addition to the amount, which you are willing to pay me
+for betraying my clients, you offer to reward me liberally for certain
+services that you require. May I ask what they are?”
+
+“You will learn soon enough if you accept our proposition. Let me state
+that we have unlimited funds at our disposal and stand ready to pay
+you well. It would be no exaggeration to say that in a short time you
+should be a rich man if you accept our offer. In view of our liberality
+don’t you think it behooves you to be less squeamish and ask fewer
+questions?”
+
+“I suppose it is in deucedly bad taste for me to argue with a man who
+offers me a fortune on a silver platter,” Cole admitted. “Just the same
+I can’t help wondering why you are offering such a glittering bribe to
+one who is practically unknown in his profession.”
+
+The man gave an amused chuckle. “Don’t worry about that, Mr. Cole.
+We are not in the habit of buying pigs in a poke. You have been under
+observation for some time.”
+
+“So I gathered from what the bewitching Miss—Brown told me.”
+
+“We have learned that you have a great deal of ability. You are
+fearless and persevering. You have qualities that the average
+professional detective sadly lacks, such as tact, polish, and a
+magnetic personality. In short, you are precisely the kind of man
+we need. We have reason to believe that you have discovered certain
+interesting facts in connection with Malcolm Reeves’ disappearance,
+facts which would naturally become our property if you came over to our
+side.”
+
+Cole marveled at the extent of the man’s knowledge. It was true that he
+had picked up several stray facts which, when considered in conjunction
+with the known circumstances of Reeves’ disappearance, made a fairly
+interesting showing. His glance wandered over the circle of veiled
+faces. Each of the seven men was watching him intently through the
+slits in his mask.
+
+“We are waiting for your decision, Mr. Cole,” remarked the spokesman
+after a pause. “If our proposition appeals to you, name your price.”
+
+Cole pretended to hesitate. He hoped to learn a little more before he
+closed the interview. He wondered how far these men would go in their
+efforts to induce him to betray his clients and transfer his allegiance
+to themselves. “Aren’t you forgetting something?” he asked. “Do you
+realize that a man who has been bought once will probably sell himself
+again?”
+
+Though he could not see, he fancied the spokesman’s eyes were twinkling
+behind the mask.
+
+“We have considered everything, Mr. Cole. You wouldn’t sell yourself
+except to a higher bidder, and it isn’t likely any one will outbid us.
+If such a situation should arise, however, we would know how to handle
+it. What is your price?”
+
+“Suppose you name the price you are willing to pay?”
+
+There was a craning of necks, and nods and subdued whispers passed
+around the circle. Evidently the seven construed his words as meaning
+that he was yielding. The spokesman unlocked a drawer in front of him
+and placed a small package on the table.
+
+“Twenty-five thousand dollars,” he remarked impressively. “If you are
+in doubt as to the amount, or if you suspect that I am handing you
+stage money, you will be permitted to examine it in the light.”
+
+He handed the package to Cole. “Remember that this is only your
+retaining fee, so to speak. There will be lots more coming to you if
+you decide to throw in your lot with us.”
+
+Cole felt the crisp fiber of the bills. He did not doubt that the money
+was genuine or that the package contained the exact amount mentioned
+by the spokesman. Whatever else these men might do, he did not think
+they would stoop to petty cheating. An odd sensation surged through him
+as he weighed the currency in the palm of his hand. It was more money
+than had ever before come within his reach. Of a sudden he remembered
+some of the things he had been compelled to deny himself because of
+his slender and uncertain income. Until this moment, when he held the
+wherewithal in his hand, it had not occurred to him that he was missing
+any of the good things in life. He had accepted his privations, as a
+matter of course, with a smile or a shrug, according to his mood of the
+moment.
+
+For a few seconds longer he gave himself over to thrill of possession,
+and then he tossed the bundle of currency down on the table. “It isn’t
+enough,” he declared.
+
+A chorus of murmurs went around the circular table. The veiled faces
+strained forward a little. Once again Cole fancied the spokesman’s eyes
+were twinkling through the orifices in the mask.
+
+“Splendid, Mr. Cole,” said the man approvingly. “I didn’t think
+twenty-five thousand would satisfy you, but I wanted to make sure. As a
+matter of fact, if you had accepted such a paltry amount, we would have
+broken off the negotiations instantly. We don’t want a man who holds
+himself cheap. Here”—again he opened the drawer in front of him—“is
+another twenty-five thousand. That makes fifty. Quite a neat sum for a
+man whose income last year was only a trifle over four thousand.”
+
+“How did you know that?”
+
+“Income-tax reports,” said the man.
+
+Cole took one bundle of currency in each hand. He was no longer
+marveling at the surprising sources of information that seemed to be
+open to these men. For the moment all his senses were centered on the
+wealth that lay in his palms. A flash of self-revelation came to him,
+and he was surprised and frightened by it. He had never known that mere
+money could give him such a delectable sensation. In the past, as a
+passive onlooker, he had smiled tolerantly at other men’s scramble for
+wealth. With philosophic eyes he had watched the money-mad procession
+sweep by him. Now he found that the sheer touch of the currency sent a
+contagion through his veins, awakening strange emotions within him.
+
+The sensation put an indefinable fear into him, fear of himself and
+the weakness he had just discovered. Of a sudden the currency seemed
+to scorch his palms. He shrugged, and the spell was broken. With an
+inward paroxysm he flung the money down on the table. “Not even that is
+enough,” he announced in slightly dazed tones, like one just awakening
+from a dream.
+
+The spokesman’s head came up a little. With a shrug and an indistinct
+mutter he once more opened the drawer, but Cole laid a detaining hand
+on his sleeve.
+
+“Wait!” he said quietly. “You are going ahead on the idea that every
+man has his price. You’re mistaken. There isn’t money enough in the
+whole United States treasury to buy me.”
+
+There came a hush, and then a ripple of commotion went around the
+table. It died instantly as the spokesman raised a silencing hand. He
+tilted his head back, and through the holes in the mask his eyes bored
+into Cole’s face. For a time not a sound was heard in the room. Finally
+the spokesman gave a short, contemptuous laugh. “I see,” he declared.
+“You’re a weakling like most men. You’re a slave to the absurd thing we
+call conscience. I had hoped that you were one of the rare exceptions.”
+
+“Wrong again,” said Cole, smiling. “It isn’t conscience. Anyway, I
+wouldn’t call it that. It is only pride, a foolish pride, perhaps. I
+want to go through life knowing that I can look every man straight in
+the eye and tell him to go to the devil if necessary. I couldn’t do
+that if I were to sell myself. I should become a despicable thing in my
+own eyes, and life wouldn’t be worth living after that. I don’t suppose
+you understand, but that’s just how I feel.”
+
+Seven pairs of eyes were leveled at Cole’s face as his short, crisp
+sentences fell on the tense air. Then came silence, a long and oddly
+vibrant silence during which Cole experienced an unaccountable feeling
+that his life hung in the balance. He could neither understand it nor
+trace it to its source, but the nameless sense of danger grew more
+distinct with every moment.
+
+By instinct his hand went to the hip pocket in which he always carried
+a small, but reliable, pistol. Before his hands could touch the weapon
+a strange thing happened. The spokesman’s arm described a slight
+movement in the dusk, and in a twinkling utter darkness fell. Cole
+stood in blackness so intense that it seemed as though he could touch
+it.
+
+His fingers found the handle of the pistol, but in the next instant his
+hand fell to his side. In that impenetrable darkness the weapon was of
+no more avail than a toy. He heard a faint scraping of chairs, then a
+patter of feet. He groped for the chair where the spokesman had sat,
+but it was empty. Gradually the faint sounds ceased, and then came an
+engulfing silence. It was as if every manifestation of life had been
+drained out of the blackness that surrounded him.
+
+Silence—darkness—solitude. Cole, as he dropped into the spokesman’s
+chair, felt as if the three words had suddenly acquired a new and more
+powerful significance.
+
+
+
+
+ CHAPTER III
+
+ THE TEMPTRESS SPEAKS
+
+
+Five minutes passed. Cole could no longer control his restlessness. He
+got up from the chair and went gropingly across the heavily carpeted
+floor. His footsteps made scarcely a sound, and he had a queer
+sensation that the darkness and silence were insinuating themselves
+into his very pores. It was as if a magic spell had fallen over him. He
+could no longer trust his reason or his senses.
+
+He stopped short as a faint whisper went through the dead silence. With
+head thrown back and straining his ears, he listened. Again the whisper
+came, trailing through the blackness like a disembodied breath. He
+groped in the direction whence the sound came, and now he could hear it
+quite distinctly.
+
+“Mr. Cole!”
+
+Tracing the sound vibrations, he crossed the floor and brought up
+against the wall. Again his name was spoken, and now he had an
+impression that the speaker was only a few feet away. He thought he
+recognized the voice.
+
+“Mr. Cole!”
+
+His highly sensitized ears gauged and dissected each small fraction
+of a syllable. He knew he was not mistaken. The voice belonged to the
+woman who had introduced herself by the absurdly inappropriate name of
+Miss Brown.
+
+“Where are you?” he asked. He fumbled with his hands in the dark, but
+found nothing but emptiness. He turned and ran his fingers up and
+down the wall until he encountered a metallic object imbedded in the
+paneling. Again his name was called, and he gave a short laugh as he
+realized that the sounds were coming to him through the mouthpiece of a
+speaking tube. The touch of the cold metal against his fingers seemed
+to shatter an illusion. Simple though the contrivance was, it smacked
+of up-to-dateness. A sense of reality broke the spell which the weird
+events of the night had cast over him.
+
+“Hello,” he spoke into the mouthpiece. “You, Miss Brown?”
+
+A brief pause, and then her voice came to him in hurried tones that
+bespoke intense excitement. “Yes, Mr. Cole. I must warn you. I feel
+responsible for your predicament. Awful things will happen if you
+persist in your headstrong course. You must abandon it and accept the
+proposition that was made to you. Otherwise——”
+
+Her voice quavered and broke. The suspended sentence and the words she
+had left unspoken impressed Cole grimly. He could almost see her, white
+and shuddering at the other end of the speaking tube. Though he knew
+she was a clever actress, there was an earnestness in her tones that
+gave him pause.
+
+“You mean these men will kill me unless I accept their vile terms?” he
+asked.
+
+“Oh, they will do worse than that! They are terrible men, Mr. Cole,
+and they are in a desperate temper. Death, a hundred deaths, would
+be preferable to the thing they intend doing. Won’t you come to your
+senses before it’s too late? Oh, please——”
+
+Cole laughed into the mouthpiece. “Compose yourself, Miss Brown. Don’t
+worry on my account. I’ve been in tight corners before, and I always
+wriggled out of them somehow. I shall do so this time.”
+
+A sob sounded at the other end, and then all was quiet. Cole drew away
+from the speaking tube. It might have been only another bit of clever
+acting, but Miss Brown’s warning had left him in a state of tingling
+suspense. She had hinted at dire things that were to happen to him,
+and Cole tried to tell himself that she had only been exercising
+her imagination. Such things belonged in the realm of romance and
+melodrama. It was laughable to think that they might happen on the top
+floor of a skyscraper, located close to the world’s financial nerve
+center. The incongruity of it struck Cole as quite amusing.
+
+He chuckled, but in the next instant he sharply caught his breath. A
+sound resembling that of a clicking lock reached his ears. He heard
+nothing more, but he had a feeling that some one had entered the room,
+that he was no longer alone. Instinctively he braced himself to resist
+an attack. His ears were keyed to catch the slightest sound; every
+muscle in his body had the tension of a cocked trigger.
+
+He stood with his back against the wall, all his senses quiveringly
+alert. He could neither hear nor see, but he knew some one was
+steadily approaching from the farther end of the long room. Presently
+he could hear sounds of breathing, but the prowler’s progress was
+still muffled by the heavy carpet. Now a little thud signified that
+the intruder had walked up against the circular table, so he could
+be no more than a few feet from where Cole stood. The fact that he
+could not see who it was that was coming toward him made the suspense
+nerve-racking.
+
+Suddenly he thought of matches. He searched his pockets, but the little
+case in which he usually carried them was empty. Somewhere in the room
+there must be an electric-light switch, but it was not likely he could
+find it in the dark.
+
+He peered sharply into the blackness. Now his ears caught a pawing
+sound, like that of some one crawling on hands and knees. He bent
+forward a little, shoulders squared, for he knew the prowler was only a
+foot or two away. Evidently he hoped Cole was unaware of his entrance
+and expected to take his victim by surprise.
+
+A fumbling hand swept Cole’s knees, and he kicked out his foot with
+great force, foiling the attempt to trip him. A startled yell testified
+to the effectiveness of the kick, but in the next instant Cole knew
+that his adversary had risen to his feet and was changing his tactics.
+His fist struck out, but it landed on a body hard and firm as rock, and
+the only apparent result of the blow was a stinging sensation in his
+knuckles. He tried to strike again, but now his shoulders were seized
+in a powerful grip that pinned his arms to his side and rendered him
+helpless.
+
+His mind worked quickly, while the enormous weight of his adversary
+bore him down. Evidently he was a huge man, and his arms were hard
+as flails. Even if Cole’s hands had been free, his fists would have
+made no stronger impression on the man’s body than on a wall of brick.
+Though nimbler and more wiry than his opponent, Cole knew he could not
+match him in brute strength and physical endurance. His only hope lay
+in releasing his arms and, striking at the fellow’s face, batter him
+into insensibility.
+
+He writhed and wriggled in the powerful embrace of the gigantic arms,
+resisting the downward pressure till he felt as if his spine must snap.
+Inch by inch his opponent was bending him to his knees, and all the
+while his arms felt as if they were caught between metal springs. In
+vain he put every ounce of strength into the struggle; the mountainous
+body of his adversary was constantly forcing him downward. Already his
+knees were touching the floor, and his neck felt as if it were being
+gradually wrenched out of shape.
+
+His breath grew weak and fluttering. His heart pounded against his ribs
+like a trip hammer. In the blackness tiny specks whirled before his
+eyes. He knew the struggle must end soon, and the realization seemed
+to kindle a flame within him. An idea shot like a flash through his
+reeling mind.
+
+Suddenly he grew limp in the sturdy arms of his opponent. With a
+grunt of satisfaction the latter let go his hold, and Cole lay flat
+and inert on his back. For a few moments he drank huge gulps of air
+into his straining lungs. Then, with the elastic swiftness of a spring
+suddenly released, he leaped to his feet. With one hand he located his
+adversary, with the other he drove a savage blow straight into the
+man’s face.
+
+A short cry of pain and rage broke from the other’s lips. His hands
+fumbled at Cole’s throat for a strangle hold, but the merciless
+hammering of the latter’s fists drove him steadily backward. Whenever
+his fingers tightened around Cole’s windpipe a rain of smashing blows
+to nose and mouth forced him to relax his hold and retreat a little
+farther toward the wall. Cole, his strength electrified by the joy of
+battle, did not notice that his knuckles were bruised. Time and again,
+with a sureness of aim that surprised himself, he drove them into the
+other’s torn and mangled face. Already a stertorous breathing told that
+his adversary was becoming groggy. Cole summoned all his strength for a
+final knock-out blow.
+
+He flung his arm backward, and in the same instant the other uttered a
+loud yell. Cole cut it short with a crashing thrust of his fist. With a
+gasp his opponent went to the floor. For a moment he gave himself over
+to the thrill of victory, but in the next instant he was all alertness.
+A faint click signified that the door had opened, and now several pairs
+of feet were stealing swiftly across the floor.
+
+Cole whirled around on his heels, but a stalwart form collided with
+him, nearly sweeping him off his feet. Another hurled himself upon him
+from behind, and a third jerked his legs from under him. With a sharp
+sense of bafflement, Cole fell headlong to the floor. He struck out
+with hands and feet, fighting with desperate vehemence, determined to
+inflict all the injury he could on his opponents.
+
+But he was outnumbered three to one, and something of his strength had
+been spent in the earlier encounter. Defiantly he met the onslaught,
+but he was overpowered by numbers. Eventually they laid him on his
+back, and then his adversaries shackled his hands and feet with stout
+cord. He thought they were handling him with strange gentleness, and he
+wondered if they were saving him for another ordeal. He remembered, as
+he was picked up and carried, that Miss Brown had said something about
+a fate worse than a hundred deaths.
+
+In silence the little procession passed through a door, and presently
+Cole was placed on a cot. In a few moments the men walked out, and once
+more he was left alone in impenetrable darkness. Not a word had been
+spoken by his captors, and he had not obtained a single glimpse of
+their faces. The whole episode had been enacted in silence and under
+cover of darkness.
+
+The door opened just as his mind was shaking off the numbness that had
+seized it when he fell. Some one walked up to the cot where he lay. For
+a few moments no sound was heard save the slow breathing of the two
+men. Finally the other spoke, and Cole recognized the voice of the one
+who had acted as spokesman for the group around the circular table.
+
+“You’re an obstinate man, Mr. Cole. We have made you a very flattering
+proposition, and you have seen fit to reject it. I have come to offer
+you one more chance to comply with our wishes.”
+
+“And if I refuse,” said Cole evenly, “you will kill me, I suppose. I am
+beginning to think you are quite capable of it.”
+
+“Oh, no!” The other man laughed softly. “We know you are not the kind
+of man that’s afraid of death. Something stronger than fear for your
+life is needed to bend you to our will. But we will bend you sooner or
+later. Make no mistake about that.”
+
+The words were spoken in a tone of calm assurance that impressed Cole
+against his will.
+
+“How, if I may ask?”
+
+“By a form of persuasion that is far more powerful than the fear of
+death. After all, death is nothing. Only a dip into a void. A little
+suffering, perhaps, and then nothingness. There are things that are far
+worse. Mr. Cole, did you ever stop to consider what your life would
+amount to if you should suddenly lose your mind?”
+
+“What?” Cole gave an involuntary shudder.
+
+“Suppose that keen mind of yours should become a blank. Suppose that
+your wonderful mental faculties were to desert you, that you were to
+become a leering, tottering wretch, inspiring loathing and horror in
+your fellow men. Can you picture such a fate, Mr. Cole? Death would be
+a thousand times more merciful, yet you would lack the incentive to
+kill yourself. What could be worse?”
+
+Cole was silent. The darkness gave free rein to his imagination, and
+the picture he saw sent a cold shiver down his spine.
+
+“All that life means to you would be blotted out,” the other went on
+with remorseless eloquence. “Instead of matching your wits against a
+man’s problems, as at present, you would probably be devoting your
+time to childish amusements. Imagine yourself placing buttons in a row
+and building houses out of blocks. You would be dragging a useless and
+broken body through life until——”
+
+“Stop it!” said Cole. “You’re in more danger of losing your mind than I
+am. Yours is already a bit twisted, unless I’m mistaken.”
+
+“Don’t fool yourself. Unless you give us a reasonable guarantee that
+you will comply with our wishes, you will be a grimacing lunatic by
+morning. A very simple operation on the brain will do it. Among those
+seven men whom you saw around the circular table is a noted surgeon.
+Everything, including the ether and the instruments, will be ready in a
+few minutes. There is still time for you to come to your senses.”
+
+In the back of Cole’s mind was a hazy suspicion that he was dreaming,
+but the other’s calm and softly penetrating tones gave him a feeling of
+reality.
+
+“You wouldn’t——” he began.
+
+“Ah, wouldn’t we? Just wait and see. Perhaps I can convince you.”
+
+Cole heard his footfalls cross the floor, and then a door opened and
+closed. For a few minutes he was alone, trying to arrange in an orderly
+process the odds and ends of the night’s amazing happenings. His
+mind staggered before the task, and suddenly the door opened again.
+He had a vague impression that two men were entering, and that they
+were carrying a burden between them. They moved about quickly in the
+darkness, and now and then they whispered in tones so low that Cole
+could not hear them.
+
+A light flashed on, and in the same instant the door closed. After the
+long period of utter darkness, the sudden glare had a blinding effect.
+Cole blinked his eyes, but after a little he opened them wide in
+astonishment, and the sight that met them drew a long, trembling gasp
+from his lips.
+
+There was only one other man in the room, a shivering, gibbering wreck
+of a man whose grimacing features and hollow cackle sent a series of
+chill shivers through Cole’s body. For a long time he stared into the
+leering, slowly twitching face before he was able to realize that the
+wretch, seated a few feet from his cot, was Malcolm Reeves.
+
+
+
+
+ CHAPTER IV
+
+ “YELLOW”
+
+
+When he first went to work on the case of Reeves’ mysterious
+disappearance, Cole had been shown several photographs of the missing
+man. Along the numerous twistings of the trail, he had carried with him
+a mental picture of a fine intellectual face, deep and rather somber
+eyes, a long nose, whose slenderness hinted at aristocratic breeding,
+a clean-cut jaw that denoted a great deal of aggressiveness, and lips
+that were a trifle too full and might have suggested sensuality, if the
+broad slope of the forehead had not conveyed a dominant impression of
+the student and the thinker. The picture in Cole’s mind had represented
+a man about fifty years old, with a virile personality and quiet tastes.
+
+The contrast between his mental image of Malcolm Reeves and the
+miserable creature, now sitting a few feet away, was so sharp that the
+comparison gave Cole a profound shock. His clothing hung loosely over
+his bony frame, and he seemed to have aged decades in the three weeks
+that had elapsed since his disappearance. His shoulders were hunched
+down a little, his head was bent forward, and the eyes stared rigidly
+into space, as if he were seeing something in the distance. His lips
+were twisted into a fixed, vacant smile that impressed Cole as the most
+hideous thing he had ever seen.
+
+He tried to spring from the cot, momentarily forgetting that his arms
+and legs were bound. He sank back with a mutter of exasperation. Not
+much imagination was required to guess that the men who had brought
+about his own plight were also responsible for the condition of Malcolm
+Reeves.
+
+Again something drew his glance to the insane man. The revolting
+picture seemed to hold Cole with an uncanny fascination. “What’s
+happened?” he inquired, realizing a moment later that he might as well
+have addressed a wooden image.
+
+Reeves was still gazing fixedly at the opposite wall. There was a look
+of insane glee in his shrunken eyes. He bent forward a little more, and
+then his lips began to move. “Yellow,” he said. “Pretty yellow!”
+
+The soft-spoken words and the giggle that followed caused Cole to
+shudder. He could see that Reeves’ mind, or the pitiful remnant of it,
+was reveling in some childish fancy. The wreckage of a once splendid
+intellect was horrible to behold.
+
+“What do you see?” he asked, wondering whether the man was capable of
+any form of response.
+
+The other’s face brightened, but Cole thought it was only an external
+glow, a reflected light rather than one kindled from within. He
+recoiled inwardly as another stream of giggling mirth flowed from the
+insane man’s lips.
+
+“Yellow,” said Reeves again. “Pretty yellow!”
+
+His expression became more rapt. His smile grew broader and deeper, but
+to Cole it seemed nothing more than a contortion of facial muscles.
+He wondered whether the two words were all that was left of the man’s
+vocabulary. He felt a desire to test him and see if there was not a
+remaining scrap of intellect that could be aroused.
+
+“Listen, Mr. Reeves,” he said sharply. “When did you last see Professor
+Carmody?”
+
+The giggling ended in a quick intake of breath. Reeves’ smile faded
+as abruptly as if an invisible hand had blotted it out. Watching him
+intently, Cole could see that his question had touched a slumbering
+chord in the man’s mind. Fear and something akin to hate blazed in the
+shrunken eyes. It was a startling transformation, and Cole observed it
+in wonder. He had mentioned Carmody’s name on the spur of a vagrant
+impulse, wondering whether it would awaken a recollection in the débris
+of Reeves’ intellect. The effect was far beyond his expectations.
+
+“Carmody!” said the insane man, and each syllable cut like a knife
+through the silence. “Carmody!”
+
+He drew a shaking hand across his brow, and Cole fancied something was
+stirring in the dark corners of his mind. His face took on a strained
+look, as if he was trying to exercise the shattered remnants of his
+intellect. There was a flicker of returning sanity, a feeble ray of
+awakening reason.
+
+It did not last long. Reeves gave a little shudder, there was a
+trembling gleam in his eye, then the fatuous grin came back to his
+lips, and once more he mumbled in rapt tones: “Yellow. Pretty yellow!”
+
+Cole turned his head away with a shiver. His experiment had shown the
+hopelessness of the insane man’s condition, but it had also suggested
+several things to Cole. A recollection of a terrifying nature
+seemed to be buried in the wreckage of Reeves’ mind, and evidently
+it had something to do with Professor Carmody. Cole had felt certain
+for a long time that the professor was responsible for the man’s
+disappearance, but he had not cared to jeopardize his case by taking
+action before he had sufficient evidence in his possession, as a
+premature move on his part might have brought disastrous results. At
+that time he had not been sure whether the missing man was dead or
+alive. If still living, his safety might be endangered by hasty action,
+for Carmody would not hesitate to kill him if he thought it advisable.
+So Cole had waited, patiently biding his time and slowly, but surely,
+strengthening the meshes in which he hoped to entangle the professor.
+
+Now he wondered to what extent his course had been correct. The
+maniac’s startling reaction to the mention of Carmody’s name seemed to
+confirm at least a part of his theory. What he could not understand
+was how Reeves, granting that the professor was responsible for his
+abduction, happened to be in this place of dark intrigue and baffling
+mystery. Evidently there must be a connecting link between Professor
+Carmody and the seven masked men who had sat around the circular table.
+Likely as not they were accomplices, banded together for the attainment
+of some secret object. That would at least explain why the seven men
+were so determined that Cole should drop the Carmody case, though it
+explained nothing else.
+
+A slight sound interrupted the speculations with which he had tried
+to relieve the tension he felt. He turned his head a little and saw
+that the door had opened a crack. A hand was inserted through the
+narrow opening. For a moment it fumbled over the wall, then came a
+faint click, and once more the room was dark. Men were moving about in
+the black for a time, and then all was quiet. The silence seemed to
+indicate that Cole was alone in the room, but he had an indefinable
+feeling that some one was standing beside his cot. In a moment his
+impression was confirmed.
+
+“Mr. Cole,” said a voice, and he recognized it at once, “I trust that
+what you have just seen has put you in a more reasonable frame of mind.
+Unless you comply with our wishes we shall do to you what we did to
+Malcolm Reeves.”
+
+Cole strained spasmodically against the cords that fettered his hands
+and feet. In the darkness his imagination sketched a picture of Reeves’
+hideously grinning face. For a moment he could almost hear the maniac’s
+insane cackle. He banished the vision by sheer force of will.
+
+“There’s a great deal of finesse about your methods,” he ironically
+observed. “I guessed, of course, that Reeves was brought in here to
+serve as an object lesson to me. It was quite impressive.”
+
+“And you have reconsidered?” asked the other hopefully.
+
+Cole lay absolutely still on his back. It was all he could do to
+exclude the disturbing pictures of Reeves from his mind. Whenever a
+glimpse of it came back to him he felt a weakness that put him in fear
+of himself. “Not exactly,” he managed to say in steady tones. “I have
+merely been taking my own measure, as it were, trying to determine
+whether the loss of pride and self-respect is worse than the loss of
+one’s sanity.”
+
+“And what is your conclusion?”
+
+“I am still in doubt. There are so many ways of looking at the
+situation. For instance, one thing to be considered is that lost
+self-respect may be regained, while insanity is in most instances
+incurable.”
+
+“Excellent,” murmured the other. “That’s a very rational way of looking
+at the proposition. Such being the case it should not be difficult for
+you to choose between the two alternatives.”
+
+“But it is,” protested Cole. “There is still another thing to be
+considered. Suppose I were to accept your terms. All I could give you
+would be my word of honor that I would live up to them.”
+
+“Quite sufficient,” the other put in. “We know you are not the kind of
+man who goes back on his word.”
+
+“Thanks,” said Cole sarcastically. “Just the same one’s word of honor
+is a rather intangible thing. You can’t bind me with a contract. It
+would not be legal, no matter how ingeniously worded, and it might
+incriminate yourselves. I am not in position to give you any pledges.
+You would have to be content with my bare promise. It would be
+sufficient in any ordinary case, but circumstances alter everything. I
+realize I am at the mercy of a gang of unprincipled scoundrels.”
+
+“Your epithets don’t hurt us in the least,” remarked the other man
+icily.
+
+“Didn’t expect they would. But don’t you see that, under the
+circumstances, I would have no hesitancy at all about giving you a
+promise that I didn’t intend to keep? I am not a bit quixotic, and I am
+too practical to indulge in cheap heroics. I have no ambition to become
+the hero of a tawdry melodrama. In order to escape a fate like the one
+you inflicted on Reeves, I would promise anything, and so would every
+other man whose head isn’t full of moonshine. You follow me?”
+
+“Perfectly. You are trying to make out that we have no hold over you.
+Your reasoning isn’t bad, but you forget one thing. As it happens, we
+are in a position to exact a pledge from you, one that will hold you to
+us for life.”
+
+“What is it?”
+
+The other gave a soft laugh. “You saw what a hopeless case Reeves is.
+There’s no reason why he should go on living any longer. The merciful
+thing to do is to put him out of his misery.”
+
+“You mean——”
+
+“Exactly, Mr. Cole. You are to seal the promise you give us by hustling
+Reeves off to a better world. We have planned it so that we will be
+able to prove that you killed him. Having incriminated yourself to that
+extent, and with the evidence in our possession, we need have no fear
+that you will go back on your word of honor. And now that we thoroughly
+understand each other, I must ask you to decide promptly. Our time is
+valuable.”
+
+A few moments passed in silence, but to Cole they were like weeks.
+Never before in all his life had so many thoughts and emotions been
+crowded into such a narrow space of time. He felt weak and shaken when
+it was over, but his voice was clear. “My answer is no,” he declared.
+“If I were able I would give it to you in a more emphatic manner.”
+
+“Sorry, Mr. Cole,” replied the other. “I won’t accept your decision
+as final, however. I trust you will reconsider before you become
+unconscious under the ether.”
+
+With that he went out, leaving an ominous silence behind him. Cole
+tore frantically at the cords around his wrists, but they only cut the
+deeper into his flesh. He could see no escape from the awful fate that
+awaited him. Time and again the picture of Reeves’ fatuously grinning
+face came back to him, causing him to writhe in mental torment. A
+tempting voice seemed to whisper in his ear, turning his thoughts into
+strange channels. To end a life that was worse than a living death
+appeared not such a dreadful thing to do. Cole himself would have
+preferred to die rather than suffer a fate like Reeves’. If he should
+ever fall into such a condition he would consider the man a benefactor
+who ended his misery.
+
+He shook himself violently. A clammy perspiration was bathing his
+forehead. With a mental and physical paroxysm he brushed away the
+temptation to which he had nearly yielded a moment ago. Footsteps
+were approaching the door, and he knew a critical moment was at hand.
+Something within him that was stronger than reason and logic shrank
+from the mere thought of taking Reeves’ life. He wondered if there was
+no other alternative.
+
+He tried to take a calm view of the situation. Though his hands and
+feet were tightly bound his persecutors evidently had not thought it
+necessary to strap him to the cot, since he would soon be under the
+influence of the ether. By experimenting he found that he could turn
+over on his sides and, thanks to the fact that his hands had been tied
+in front instead of behind, he was able to move his arms up and down
+and in a horizontal direction. Since he could not use his hands he did
+not see how he could turn this circumstance to his advantage, yet it
+continued to tantalize his imagination.
+
+The door opened, and his ears told him that several men were entering
+the room. For a time they moved about in the darkness, as if making
+preparations of some sort. After a little the footsteps receded, and
+then the door opened and closed once more. Cole guessed that all but
+one or two of the men had withdrawn. After another brief delay, the
+lights flashed on once more, this time illuminating a different scene.
+
+Reeves was back in the room, occupying the same chair in which he had
+sat the other time, but now his limbs were as tightly manacled as
+Cole’s own. He moved his head slowly from side to side, as if sensing
+something unusual in the air, but his vacant stare showed that he had
+not the faintest inkling of what was going on.
+
+After a glance at him, Cole looked away. Not far from the cot stood a
+tall man with a black beard that covered nearly his entire face. He
+was holding a number of surgical implements to the light, giving each
+one a critical inspection before he placed it on a small table with a
+glass top that stood beside the cot. Cole could not restrain a shudder
+as he saw how calmly the man examined the sinister-looking little
+tools. There was a professional air about him that in Cole’s mind
+stamped him as a surgeon.
+
+Again his glance moved to the insane man, whose dull gaze seemed to be
+taking in each detail of the scene. The meaning of the little knives
+and the presence of the black-bearded man was terrifyingly clear.
+
+The surgeon placed the last of the knives on the table beside the
+cot. They lay there in plain view, so close to Cole that if his hands
+had been free he could have reached out and touched them. The long,
+slender metal blades gleamed diabolically in the electric lights, and
+he wondered if they had been placed like that for the sole purpose of
+impressing their hideous significance upon him.
+
+The black-bearded man came closer to the cot, and Cole caught a full
+view of his face. He had seen it once before, though only dimly,
+for the surgeon was one of the seven who had sat in the dusk at the
+circular table. He had worn a mask then, but the black beard, the high
+forehead and the bald spot on top of his head were unmistakable. Now
+his features were unveiled, and in this circumstance Cole saw a grim
+significance. The surgeon no longer had any reason to fear that Cole
+might recognize him if they should meet again.
+
+He stopped beside the glass-topped table and, with hands clasped at his
+back, fixed a tranquil gaze on the reclining man. “You have one more
+chance, Mr. Cole,” he remarked in a casual tone. “Hadn’t you better
+reconsider your refusal?”
+
+Cole looked up into the bearded face with a feeling that there was
+something peculiar about it, but his mind was too agitated to analyze
+the impression. In a playful manner the surgeon picked up one of the
+knives, holding it so that the light flashed against the keen blade.
+
+Cole was trying to frame an answer, but just then something drew his
+gaze to the insane man. Reeves was straining forward in his chair,
+bending his weight against the fettering cords. From where he sat he
+had a clear view of both Cole and the surgeon, and his eyes were fixed
+with wild intensity on the knife in the latter’s hand. Time and again
+he opened his lips, but the only sound that came was a hoarse rattle in
+his throat.
+
+“Well, Mr. Cole?”
+
+The surgeon, paying no attention to the lunatic, looked impatiently
+at Cole. Reeves, with mouth gaping and features horribly distorted,
+continued to stare at the knife.
+
+“You refuse?” The surgeon waited a moment longer for an answer; then,
+with a shrug, he replaced the knife and stepped aside. Cole felt a
+sudden rush of blood to his head. If he was to escape a fate worse than
+death he must act at once. He spurred his wits to think of something
+to do. A tinkling, like that of a jar or a bottle being moved, sounded
+in the room. Again he bent his mind to the seemingly hopeless task
+of finding a way out, but, even in this moment of desperate peril, he
+could not take his gaze from the insane man’s face.
+
+Reeves sat with shoulders hunched up and head turned a little to one
+side. Now and then his mouth twisted at the corners; from time to time
+a shudder broke the tension of his figure. A series of slight gurgling
+sounds fell on the stillness at intervals. All the while his eyes, with
+a smoldering something in their depths, were fixed on the knives spread
+out on the glass-topped table.
+
+Suddenly Cole’s body executed a little writhing motion. His nostrils
+sucked in a strong, sickening odor. With a sponge in his hand, the
+surgeon was coming toward the cot.
+
+Once more, in a delirium of suspense, Cole glanced at the insane man.
+The quick dilation of Reeves’ nostrils told he also had noticed the
+ether. The chair creaked as he put his weight against the cords. There
+was a look on his face that Cole felt would follow him through the
+night of madness that threatened to engulf him. Reeves’ chest heaved
+violently, his whole body seemed to be rocked by a tumultuous emotion,
+and finally a long and oddly vibrant cry broke from his lips.
+
+
+
+
+ CHAPTER V
+
+ DISGUISED
+
+
+To Cole’s rapt gaze the insane man presented a picture at once fearful
+and fascinating. Reeves was no longer looking at the keen-bladed
+knives, but now he was staring at the black-bearded surgeon with an
+intensity that seemed to strain every nerve and muscle in his body. The
+knotted cords at his temple swelled and took on a livid hue. Slowly and
+shakily he drew himself erect in the chair, and then his whole body was
+rocked by a paroxysm so violent that, for an instant, Cole thought the
+cords were about to snap.
+
+The surgeon, with the reeking sponge in his hand, turned and watched
+the maniac. A smile twisted the bearded lips, and he stepped to the
+chair and spoke a few words in Reeves’ ears. The insane man’s chest
+heaved out, but the cry and the paroxysm seemed to have exhausted his
+energies, and only a feeble, fluttering moan came.
+
+The spectacle had held Cole spellbound. Now, while the surgeon was
+leaning over the insane man and whispering in his ear, a sudden
+realization of his peril caused him to throw off the weird fascination
+which the scene had cast on him. He had only a few moments in which to
+act. Soon the reeking sponge would be at his nostrils, deadening his
+mental faculties.
+
+His darting glance fell on the knives lying on the glass-topped table
+beside the cot. They were so close to him that they seemed to mock and
+taunt him. Again it occurred to him that they had been placed like that
+for the sole purpose of impressing their infernal purpose upon him and
+battering down his fortitude. It had been a touch of refined cruelty
+on the black-bearded man’s part, but it only strengthened Cole’s
+determination not to yield.
+
+Suddenly, as he kept looking at the knives, the gleam of an inspiration
+crept into his narrowing eyes. He cast a swift glance about the room.
+The black-bearded man was still occupied with Reeves and stood with his
+back turned to the cot. Cole, trembling with excitement, turned over on
+his side and wriggled as close to the edge of the cot as he could. He
+reached out his manacled hands over the glass-topped table. The cords
+around the wrists gave the fingers considerable leeway. In an instant
+they had closed around the handle of the nearest knife.
+
+Cole tingled from head to foot. The subtle bit of strategy by which the
+black-bearded man had hoped to shatter his victim’s nerve had now been
+turned to Cole’s advantage. It gave him a fighting chance, though the
+odds were still overwhelmingly against him. His lips curled a little,
+and there was a belligerent sparkle in his eyes. Turning over on his
+back he dropped the knife beside him on the pillow, so that his head
+would temporarily screen it from the surgeon’s sight. Then, letting his
+arms fall limply back against his abdomen, he waited for the surgeon to
+act.
+
+Presently the black-bearded man turned away from Reeves and stepped up
+to the cot. Cole lay motionless, with eyes half closed, as if partly
+dazed by contemplation of the terrible fate that awaited him. Inwardly
+he was straining and quivering with suspense. As yet the surgeon did
+not seem to have noticed that one of the knives was missing from the
+table, but he might do so any moment, and then Cole’s only hope would
+be gone.
+
+“Well, Mr. Cole?” he asked lightly. “For the last time I ask you to
+reconsider your refusal.”
+
+Cole lay very still. The last few minutes of suspense seemed to have
+wrought a great change in him. His lips moved as if he were trying to
+speak, but was too weak to use his voice.
+
+The surgeon grinned into his beard. Evidently he thought the knives
+placed so close to his victim’s side had exerted the intended
+psychological effect.
+
+“Have you anything to say?” he asked, bending over the cot in an effort
+to catch Cole’s faintly mumbled words.
+
+Cole flexed his muscles for action. The moment for which he had waited
+was at hand. His chance had come; everything depended upon how he used
+it. He mumbled again, and the surgeon’s head came a little closer to
+his chest.
+
+“A little louder, please,” said the black-bearded man.
+
+Slowly, by imperceptible degrees, Cole drew up his manacled hands
+toward his chin. Suddenly his arms shot upward, forming a circular loop
+that instantly descended over the surgeon’s head. With a startled cry
+the black-bearded man tried to draw back, but the arms that encircled
+his shoulders were as strong and hard as springs of steel. He
+struggled frantically, but the encircling grip pinned his arms tightly
+to his sides, and his head was constantly being forced lower and lower
+toward the reclining man’s chest. The sponge had dropped from his hand
+the moment Cole’s arms were flung around his neck.
+
+An exultant thrill went through Cole as the other’s resistance grew
+feebler. Now the surgeon’s head was almost level with his face. The
+only sounds in the room were the hard panting of the adversaries and
+an occasional giggle from the insane man. Fumes of ether were slowly
+filling the air.
+
+Cole turned his head. In an instant the handle of the knife was firmly
+gripped between his strong, even teeth. He thrust out his jaw, and the
+point of the weapon grazed the black-bearded man’s throat. Cole saw
+a look of fear creep into the man’s eyes. The surgeon made a final
+attempt to wriggle free, but Cole’s arms held him as in a vise. Once
+more the knife, tightly clasped between Cole’s jaws, scratched the
+other’s flesh. He remarked again the look of terror that was stamped
+on the surgeon’s face. In view of the diabolical fate which the man
+had meant to inflict on him Cole was human enough to enjoy the other’s
+agony.
+
+Suddenly he bent a sharper look on the man’s face. Once before he had
+wondered why there seemed to be something peculiar about it, but this
+was his first chance to examine the features at close quarters. Now he
+noticed that the beard which covered most of the face had an unnatural
+appearance. There were lines about the eyes that did not seem quite
+genuine, and the exposed portions of the skin had an odd coloring.
+Obviously the man was disguised, and Cole could see that it had been
+rather cleverly done. He wondered why the disguise had been put on,
+since the surgeon had had every reason to expect that Cole would
+leave the room a raving lunatic and that there would be no danger of
+recognition if they should meet again.
+
+He had not time to think further about it. The deadlock was only
+temporary; any fortuitous incident might upset Cole’s advantage;
+instantly the door might open and admit one or more of the other
+members of the gang. Just now he had the surgeon at his mercy. Only a
+little slash with the knife, clamped between his teeth was needed to
+open an artery, but that would not release him from his predicament.
+Though he might be able to sever the cords around his ankles he could
+not move his hands with sufficient freedom to cut the strings around
+his wrists. While he was casting about for a plan a muffled groan of
+fright and pain broke from the surgeon’s lips. Unconsciously Cole had
+once more scratched the man’s throat with the knife.
+
+“You’re killing me!” protested the other man in a feeble voice.
+
+“It would serve you right,” declared Cole unfeelingly. “I don’t know
+why I should have any compunction about killing a rat of your kind. We
+might come to some arrangement, however. What will you do if I spare
+your life?”
+
+“Anything, anything you say.”
+
+Cole considered. The thing of first importance was to get his hands
+free of the cords. In his present position, with his arms pinned
+tightly in Cole’s embrace the surgeon could not untie them, and Cole
+did not see how he could give the man any freedom of movement without
+imperiling his own advantage.
+
+“I am going to give you a chance for your life,” he said, “but if you
+make the slightest false move you die instantly. Understand that?”
+
+“I’ll do whatever you say.”
+
+“All right, then. Turn over.”
+
+Cole relaxed his hold a trifle, and the surgeon turned in his arms. The
+point of the knife did not leave his flesh for an instant, and at any
+moment Cole could have inflicted a mortal wound by merely thrusting his
+head forward. Now, with the end of the blade in dangerous proximity to
+the surgeon’s jugular vein, Cole gingerly released one of the man’s
+arms, then commanded him to untie the cords around his wrists. The
+black-bearded man obeyed, and Cole transferred the knife from his mouth
+to his right hand. In a short time his feet had been released, and now
+he flung the surgeon aside and slipped from the cot.
+
+Reeves had watched the proceeding with a dull stare. Now and then a
+hoarse giggle of glee had escaped him.
+
+The surgeon got to his feet and drew a long breath of relief. His eyes,
+with a glint of lingering fear in their depths, watched Cole admiringly.
+
+“You’re a great scrapper, Mr. Cole,” he admitted. “You turned the
+tables with a truly artistic touch. For a time I was in fear for my
+life. There was no time to explain, and you wouldn’t have believed me
+anyway.”
+
+“Explain?” Cole asked contemptuously. The little knife was still
+clutched tightly in his hand. “One doesn’t expect explanations from
+curs of your type.”
+
+The surgeon laughed, and in the same instant his fingers touched a
+button. Cole flexed his muscles for another supreme test. Out of the
+corner of an eye he watched the surgeon; the other eye was fixed on
+the door. In a moment or two it would probably open in response to
+the surgeon’s ring, and men would come tumbling upon him from all
+directions. Cole smiled grimly. He would die fighting rather than
+expose himself to the other and more terrible fate from which he had
+just escaped.
+
+The door opened, and he poised himself, ready to spring forward.
+The nerve-racking suspense, which he had undergone on the cot, was
+forgotten now. His eye was clear, and his brain was rapidly throwing
+off the ether fumes that had escaped from the surgeon’s sponge. The
+hand in which he held the knife came upward, prepared to strike down
+the first man who should approach.
+
+Some one entered through the open door, and the arm fell limply to
+Cole’s side. With gaping mouth he stared at the newcomer who executed a
+profound bow, while he pointed to the outer room. “Will you kindly step
+this way, Mr. Cole?” he asked in the courteous tones of a well-trained
+servant.
+
+Cole laughed. The sudden reaction made him feel giddy. He had expected
+at least half a dozen men to pounce on him when the door opened. By
+contrast there was something ludicrous about the salaaming figure, now
+confronting him.
+
+“If you please, Mr. Cole.” The man again waved his hand toward the
+outer room, and Cole obligingly followed his direction. There seemed
+to be nothing else to do than wait for the other side to make the next
+move. If he was walking into a trap, as appeared not at all unlikely,
+he still had the knife to defend himself with. And that was not all,
+he suddenly remembered; his pistol was still in his hip pocket. It was
+rather odd, he reflected, as he walked behind the servant, that no
+attempt had been made to take it from him.
+
+In a few moments he was back in the long room with the circular table.
+The seven masked men were again grouped around it, and the light was as
+dim as before. The servant ushered him up to the chair occupied by the
+spokesman, then silently glided away. Once more Cole felt seven pairs
+of eyes searching his face, but this time he was aware of a new quality
+in the air.
+
+“You may feel quite at ease, Mr. Cole,” the spokesman began. “I can
+promise that no harm will come to you.”
+
+The calm, matter-of-fact tones incensed Cole when he recalled by what
+a narrow margin he had escaped the fate which these men had tried to
+inflict upon him.
+
+“How magnanimous!” he gibingly exclaimed.
+
+The other chuckled. “Oh, we can understand that you don’t feel
+particularly friendly toward us. Incidentally we know all that happened
+in the other room. You acquitted yourself nobly, Mr. Cole.”
+
+“Save your compliments. They are on a par with your promises.”
+
+“You would naturally feel that way after what has happened. Mr. Cole, I
+am going to ask you to forget what occurred in the other room.”
+
+“Forget?” asked Cole incredulously, feeling as though the episode he
+had just passed through would live in his memory till his dying day.
+
+“Well, perhaps that is asking too much,” the other admitted. “By the
+way, your bitterness toward us is natural enough, but don’t you find
+some compensation in the knowledge that you have passed through fire
+unscathed? You remained true to yourself in one of the severest tests a
+man can be subjected to. Isn’t there some satisfaction for you in that?”
+
+“Oh, yes, a lot,” said Cole ironically. “It’s worth something to a man
+to know that nothing can bend him. If you expect me, however, to get
+down on my knees and thank you for giving me a chance to prove myself
+you are mistaken.”
+
+“We don’t expect anything of the kind. I am merely trying to point out
+that you have cause for self-congratulation as well as bitterness. You
+probably won’t be able to forget what has happened, but I am going to
+ask you to dismiss it from your mind temporarily, while I make a new
+proposition to you.”
+
+Cole felt a trifle dazed. The effrontery of the man was unbelievable.
+For a moment he suspected it was all a weird jest. “Go on,” he said
+dryly. “Your superb insolence interests me. I am curious to see how
+far it will carry you.”
+
+“You shall see in a few minutes. I will begin by stating certain facts.
+Perhaps later on I shall be able to prove them to their satisfaction,
+but just now I must ask you to accept them as an hypothesis.”
+
+“Proceed,” said Cole. “I’ll try to believe that black is white.”
+
+“That’s practically what it amounts to. The first fact I am asking you
+to accept on faith, for the present, is that we are not responsible for
+Malcolm Reeves’ deplorable condition. An operation was performed on his
+brain, but we had nothing to do with it.”
+
+He paused as if expecting an objection.
+
+“The second fact I am asking you to accept provisionally,” he went
+on when Cole showed no inclination to speak, “is that we are just as
+anxious to solve the Carmody case as you can possibly be. We are more
+anxious, in fact, for we know more about its vast scope and enormous
+complexities than you do. Are you with me so far, Mr. Cole?”
+
+Cole’s shoulder made a seesawing motion. The whole thing was
+preposterous, but there was a quality in the man’s tone that impressed
+him against his will. “You are asking me to believe that you are sheep
+in wolves’ clothing,” he remarked.
+
+“That’s undoubtedly how it looks to you. Won’t you try to brush
+your doubts aside, Mr. Cole? Remember that in due time I will prove
+everything I say.”
+
+Cole’s indignation was cooling. There was something about the
+spokesman that seemed to exert a subtle magnetism on him. Already his
+dreadful experience in the other room seemed dim and remote, though a
+few minutes ago he had thought it was indelibly etched on the scroll of
+his memory. “If what you say is true, then why——”
+
+“No questions, please. You would not believe me if I were to answer
+them. All I can say now is that we have excellent reasons for what we
+have done. Some time before long I think you yourself will approve
+them. Just now you must accept my statements on faith. Will you try to
+believe that we had nothing to do with Reeves’ condition and that we
+are on your side in the Carmody matter?”
+
+“You can’t deny that you tried to put me in the same condition Reeves
+is in?”
+
+“We can, but we won’t just at present. What happened in the other room
+I am asking you to dismiss from your mind in order that you may view
+the facts I have placed before you in an unbiased frame of mind. With
+that episode eliminated can’t you place a little temporary credence in
+what I say?”
+
+Cole tried to clarify his thoughts, but without much success. He
+realized with satisfaction that his hand was still clutching the
+knife. He wondered whether, but for his quickness of mind and his deft
+handling of the little weapon, he would not now be a raving madman.
+It seemed strange that he was able to think coolly about the matter,
+and stranger still that he found himself listening to the spokesman’s
+arguments with any degree of seriousness.
+
+Finally he shook his head. “It won’t quite go down,” he declared. “You
+are asking me to take too much for granted. One’s brain was made to
+think with, and your statements won’t bear too close reasoning. You
+will have to give me your proofs before I can believe you.”
+
+A pause followed his words; then a chorus of whispers went around the
+table. The spokesman leaned over and consulted the man seated beside
+him.
+
+“I don’t blame you,” he declared, again turning to Cole. “After
+all, your skepticism is quite natural. It is even a tribute to your
+intellectual powers, for only children and feeble-minded persons accept
+unsupported statements. Now, as for proofs, let me see. Would you be
+convinced if you should find the man who is responsible for Reeves’
+condition?”
+
+“You know who he is?”
+
+“We have had our suspicions for some time, but we were not certain
+until a short while ago. A delicate operation, by which certain brain
+cells were deadened, was performed on Reeves. We knew Professor Carmody
+could not have performed it, for he is not a surgeon. We began to look
+for an accomplice, and finally we found a man who seemed to fit into
+our theory of the case. Mr. Cole, did you ever hear of Doctor Dickson
+Latham?”
+
+“Never,” said Cole.
+
+“Well, certain circumstances, which needn’t be mentioned just now, made
+us believe that Doctor Latham was the man whom we were looking for. The
+matter was really of no great importance, only one of the minor angles
+of the case, but any little light, shed on the corners of the mystery,
+might help toward solving the whole. We felt fairly certain Doctor
+Latham was our man; in the last hour we have become positive of it.”
+
+“In the last hour!” exclaimed Cole. “How?”
+
+“Malcolm Reeves told us.”
+
+“Reeves told you?”
+
+“By his actions, while you were lying on the cot. We had two reasons
+for staging that little scene in the other room. The primary one we
+won’t go into at present. The other was to jog the dead part of Reeves’
+brain back to life, by having him witness the preparations for an
+operation that, in its essential aspects, must have resembled the one
+performed on himself. We hoped that the smell of the ether, the sight
+of the knives and the preparations in general would awaken a slumbering
+memory in his mind. The experiment was only partly successful, but
+Reeves’ actions proved beyond doubt that he recognized the officiating
+surgeon.”
+
+Through the dusk Cole stared into the speaker’s calm face. “Then the
+surgeon——”
+
+“You probably didn’t notice it,” the other interrupted, “but the man
+who officiated as the surgeon was disguised. The disguise was put on by
+one of our men, an expert in that line.”
+
+“I noticed it, and it was a good job,” Cole remarked. “I couldn’t see
+why it was necessary, though.”
+
+“The disguise was put on, not to hoodwink you, but for its effect on
+Reeves.”
+
+“I don’t understand.”
+
+“But you will when I tell you that the disguise gave the officiating
+surgeon a superficial, but fairly convincing, resemblance to Doctor
+Dickson Latham.”
+
+“Clever, I’ll say!” exclaimed Cole who could appreciate ingenuity even
+in men who had caused him the most agonizing moments in his life. He
+recalled Reeves’ intense agitation while the preparations were in
+progress. At the time he had not known what it meant, but he remembered
+that the surgeon had watched Reeves very closely, and this had given
+Cole his chance to snatch up the knife from the table.
+
+“There is no doubt that Reeves thought he was seeing the man who had
+performed the operation upon him,” the spokesman went on. “One of us
+was watching the scene through a small opening in the wall, and it was
+quite evident that the surgeon’s resemblance to Doctor Latham gave
+Reeves a profound shock. Our suspicions have been confirmed, but as yet
+we have no legal proof. We want you, Mr. Cole, to go out and get the
+evidence against Doctor Latham.”
+
+“Me?”
+
+“Why not? You are a detective, a very good one, though the fact
+isn’t generally known. If you find that Latham is guilty you will
+be more inclined to credit our statements and think favorably of
+the proposition we shall make you. You will leave here as you came,
+blindfolded and under guard. Until we understand each other better we
+don’t want you to learn too much about us. You will wish to sleep late
+in the morning, but to-morrow afternoon you can attack the Carmody case
+from a new angle.”
+
+“And my clients?” asked Cole.
+
+“You will be all the better able to serve them because of your
+connection with us. As soon as you have found your evidence against
+Latham, or learned enough to convince you that we are trustworthy, you
+will come here again and report. We shall find a way of communicating
+with you in due time. What do you say to the idea?”
+
+Cole pondered. He tried to analyze the situation, but all he could
+see were contradictions and perplexities. His only clear thought was
+that he had nothing to lose and perhaps much to gain by adopting the
+suggestion. His glance swept the circle of masked faces, all of them
+turned expectantly in his direction.
+
+“The idea is good,” he finally declared. “I shall pay my respects to
+Doctor Latham to-morrow afternoon.”
+
+
+
+
+ CHAPTER VI
+
+ DOCTOR LATHAM
+
+
+The sun was several hours high the following morning when Kingdon Cole
+jumped out of bed and, from force of habit, turned toward his bathroom.
+A glance into the mirror on the white-tiled wall made him start.
+
+A man, even though he have nerves of steel and a constitution hard as
+armor, can’t pass through a siege of intense mental torture without
+showing traces of it. The nerve-racking agony, which Cole had undergone
+while lying on the cot, had left marks which seven hours of sound
+sleep had not removed. There was a suspicion of pallor beneath the
+bronze of his face. The usual brightness of his eyes was dimmed by
+a smoldering flicker which hinted at a long glimpse into infernal
+horrors. His face was drawn, and there were telltale lines and furrows.
+A twenty-four-hour growth of beard did not improve his appearance.
+
+“Nerves a bit on edge,” he told himself, turning away from the mirror.
+“Look as if I hadn’t slept a wink in a week. My landlady would tell me
+I need a doctor, but a shower and a shave will make me as chipper as a
+colt.”
+
+Whistling, he stepped into the tub and turned on the water. A few
+minutes of wriggling and writhing under the icy shower would remove all
+signs of his adventure. He thrilled to the first cold splash, and then
+Cole drew back from beneath the shower. His lips twisted slowly.
+
+“Guess I’ll try a doctor instead,” he decided. “I’m really in pretty
+bad shape. Nervous symptoms are not to be trifled with. I’ll see what
+Doctor Dickson Latham has to say about my condition.”
+
+Reluctantly he turned off the cold current and resigned himself
+to a lukewarm bath that did not refresh him in the least. Not too
+graciously, for habit becomes an exalted thing with men who live alone,
+he also decided to forgo his regular morning shave. It was best, he
+whimsically reflected, that Doctor Latham should see him at his worst.
+He dressed with less than his usual care, took in the bottle of milk
+and the newspaper that were always left at his door, and, before
+starting to prepare his own simple breakfast, poured out a saucerful of
+milk for “Toots.”
+
+Toots was a white-and-yellow cat who had slipped into his rooms one
+morning and made herself at home. Cole hadn’t had a word to say about
+the arrangement. He had been helpless before Toots’ firmness, and the
+cat had made herself a fixture in his establishment. With a languid
+indifference and an occasional feline shrug she permitted herself
+to be waited on by Cole, who at times wondered whether the cat was
+patronizing him. When Toots selected his softest pillow to sleep on and
+sunned herself on his writing desk beside the window Cole felt that the
+sanctity of his bachelor existence was being violated, but the cat’s
+blandly tyrannizing ways left him without a word of protest.
+
+After breakfast he called up Doctor Latham’s office and made an
+appointment for half past two. Then he sat down with his newspaper
+and pipe, the latter a smelly affair with a bowl shaped into the
+resemblance of a monkey’s face. It was an odd conceit, and it had
+been given him in lieu of his fee by an impecunious client. Only
+once had Cole had words with his landlady, and that was when the
+well-intentioned woman had undertaken to scrape out the bowl of his
+favorite pipe with a potato peeler. Cole smoked a weird mixture,
+compounded by himself of several domestic brands and spiced with a dash
+of perique. The strong concoction was a stimulant to mental effort, but
+at first he had hesitated to smoke such pungent stuff in the presence
+of the dainty Toots. The cat had not seemed to mind, however.
+
+He turned the pages of his newspaper, but found nothing that interested
+him. At length he threw the paper aside and refilled his pipe. Toots
+was sprawled out on the unfinished manuscript of an article on criminal
+tendencies which he was preparing for a psychological review. He gave
+the cat a reproachful glance, but said nothing. There were times when
+Toots seemed to go too far.
+
+He looked out into the warm sunlight that bathed Gramercy Park, but
+his thoughts were flitting in and out of a maze of rooms on the top
+floor of a skyscraper, located somewhere in the financial center. His
+recollections of the previous night were a queer medley of horror
+and mystery, of things that were terribly vivid and others that were
+dim and disconnected like a dream. Now, as he sat in the sunlight,
+leisurely smoking his pipe, he tried to picture the mystic circle in
+the dimly lighted room. He could not quite focus his mental vision on
+the scene; it was too shadowy and unreal. The seven masked faces melted
+into a blur, then faded away completely. It was no use trying to guess
+who those seven men were, or what their amazing conduct might mean.
+Perhaps his interview with Doctor Latham would suggest a solution to
+the mystery.
+
+The idea of approaching the doctor in the rôle of a patient had been
+something of an inspiration, but he had made no plans beyond that.
+The mock consultation would give him a chance to take the physician’s
+mental and physical measure and see what manner of man he was. Cole
+was a good judge of faces and a keen observer of human nature. To him
+the slightest gesture and the most casually spoken word had a meaning
+all their own. His first aim was to find out whether Latham was the
+kind of man who might commit such an atrocious crime as the operation
+on Malcolm Reeves; after that he would let his actions be guided by
+developments.
+
+Before starting for his appointment he thought it might be well to
+gather a few facts about the physician. He consulted his copy of “Who’s
+Who.” Dickson Latham was a specialist in nervous disorders, a graduate
+of several universities, a member of several learned societies, and his
+claim to distinction rested on his having written a number of treatises
+on cerebral surgery. The last fact seemed significant to Cole. He
+closed the book, gave Toots another mildly reproachful look, and went
+out to lunch.
+
+A few minutes before half past two he rang the doorbell of the old
+brownstone house in the Sixties, just east of Fifth Avenue, in which
+Doctor Latham resided and had his office. A young woman in the
+reception room handed him a magazine six months old and asked him to
+wait. Cole sat down and glanced about him out of the tail of an eye,
+while he pretended to look at the pictures in the periodical. It was
+a commonplace room, stuffily crowded with upholstered furniture. Two
+bookcases were filled with ponderous volumes in drab bindings. It was
+the typical reception room of a fairly thriving physician who derives
+most of his patronage from the neurotic and dyspeptic individuals of
+the upper middle class.
+
+After a brief wait Cole was facing the physician across a mahogany desk
+in the inner office.
+
+“What seems to be the matter?” asked Doctor Latham in a brisk, cheerful
+voice.
+
+“Nerves,” said Cole, making a lugubrious face. “No appetite. Can’t
+sleep nights. Always tired and out of sorts.”
+
+“Well, well, that’s too bad. You do look a bit run down, Mr. Stone. Let
+me see your tongue.”
+
+“Stone” was the name Cole had given over the telephone. It had seemed
+an unnecessary precaution, since Kingdon Cole was known to only a few
+people. His name seldom if ever appeared in connection with his work
+as a criminal investigator, but Cole always practiced discretion to a
+fault.
+
+While Doctor Latham looked at his tongue and felt his pulse Cole
+studied the physician closely, without appearing to do so. His first
+glance gave him a deep respect for the skill with which the surgeon
+of the night before had been made up. Doctor Latham was an inch or so
+taller, also a trifle thinner, and his black beard had the vitalic
+sheen that is not easily imitated; otherwise the resemblance was quite
+impressive.
+
+“Let me test your heart,” said the doctor, reaching for his stethoscope.
+
+Cole bared his chest. He was already beginning to suspect that he
+was chasing a fool’s errand. Doctor Latham did not seem capable of
+deliberate wrongdoing, to say nothing of a fiendish crime. In vain Cole
+searched his face for the faintest trace of duplicity. The physician
+had the perennial optimism and the bristling cheerfulness that, in
+cases of nervous disorders, are far more efficacious than pills and
+extracts. The very tone of his voice, together with his hearty laugh,
+acted as a stimulant on jaded nerves.
+
+“There isn’t anything the matter with you, Mr. Stone,” he declared when
+the examination was finished. “I can give you a tonic if you wish, but
+a couple of days’ rest will do you more good.”
+
+Cole buttoned up his shirt and replaced his collar. He felt certain now
+that his visit to the doctor’s office had been in vain. Latham’s kindly
+smile would have disarmed any suspicions remaining in his mind. It was
+a charming smile, a flash of white teeth against a setting of black
+beard, and it gave the final magnetic touch to a compelling personality.
+
+Cole chided himself for wasting valuable time, but he wished to make
+doubly sure before leaving the office. He wondered what would be the
+effect on the doctor if he should suddenly mention the name of Malcolm
+Reeves. None at all, very likely, he told himself; yet he felt an
+itching desire to make the test.
+
+He took out his pocketbook and looked questioningly at the doctor,
+meanwhile wondering how he might mention Reeves’ name in a casual, and
+yet sufficiently abrupt, manner to make the test conclusive.
+
+“Sit down, Mr. Stone,” said Doctor Latham, waving him to a chair. “You
+interest me. What is your profession?”
+
+“Author,” said Cole, recalling that he had two volumes on criminology
+to his credit.
+
+“Ah! And what do you write?”
+
+“Trifling things,” said Cole modestly. “You probably never saw any of
+them. Such frivolous reading matter wouldn’t interest you.”
+
+“I read very little. The medical journals and a glance at the
+newspapers are about all I find time for. Do you know, Mr. Stone, that
+you puzzle me considerably?”
+
+“Indeed!” said Cole absently, still wondering how he might precipitate
+Malcolm Reeves’ name into the conversation.
+
+Doctor Latham smiled genially. A question kept teasing Cole’s mind.
+What would be the effect on that beaming countenance if he should
+suddenly speak Malcolm Reeves’ name? Probably none whatever, he once
+more told himself; but the thought continued to tantalize him.
+
+“There is a type of neurasthenic that is known to every medical
+practitioner,” the doctor went on. “Their symptoms are quite well
+defined. Their ailments are mostly imaginary. On the slightest pretext
+they will run to a physician with a long tale of woe. The physician
+in most instances, gives them a little sympathetic advice, a harmless
+tablet made up of sugar and dough, and pockets his fee. There’s nothing
+else to do. If told that their troubles exist only in their imagination
+they get offended and run to another doctor. Personally I don’t care
+for that kind of patients. Now, Mr. Stone, you don’t belong to that
+type. You are not a neurasthenic, far from it. I wish I had your
+nerves.”
+
+Cole regarded him with a questioning look.
+
+Doctor Latham laughed pleasantly. “You’re in perfect condition, Mr.
+Stone. Perhaps you have smoked too much, or taken too much strong
+coffee in the last few days, resulting in one or two sleepless nights,
+but there is nothing else the matter with you. Ordinarily you would
+have shaken off the effects with a cold shower, or a hike in the
+country. I dare say you haven’t consulted a physician more than two or
+three times since you grew up. Under the circumstances I am somewhat
+curious to know why you came to me.”
+
+Cole gave him a sharp glance, but the affably smiling face instantly
+quieted the misgivings which the doctor’s statement had aroused.
+
+“What I don’t see,” Latham went on, “is why you went to a doctor at
+all, and why to me in particular. We never saw each other until to-day.
+I don’t flatter myself by thinking that you knew me by reputation.
+People who have no regular physician usually go to some one recommended
+to them by friends. They don’t like to consult a doctor who is an utter
+stranger to them. Perhaps among my patients there is a friend of yours
+who mentioned me to you?”
+
+“That’s it exactly,” said Cole, thrilling inwardly as he saw his chance
+to pitch Reeves’ name into the conversation. “Only the other day I was
+complaining to a friend of not feeling well, and he suggested I go to
+you. His name——”
+
+“Ah,” asked Doctor Latham, speaking in very soft tones. “I wonder if
+you are referring to Malcolm Reeves?”
+
+For a moment Cole looked as if he had received a blow between the
+eyes. He gathered himself in an instant, but not before the doctor had
+noticed his surprise. The physician was still smiling, but now the
+smile was different. It was frosty and pale. “I see I guessed right,”
+he murmured.
+
+“Is Reeves one of your patients?” Cole managed to ask.
+
+The doctor leaned back in the chair, crossed his long legs, and gazed
+toward the ceiling. Cole became conscious of a distinct chill in the
+air, and he felt irritated at himself for having stumbled into the same
+trap he had set for the physician. Doctor Latham, he was beginning to
+perceive, was a man whose mental thrust was as quick and sure as his
+own.
+
+“Frankness is an excellent policy, Mr. Stone,” observed the physician
+coldly. “We shall make better progress if you will put all your cards
+on the table. You did not come here to consult me about your health.
+May I ask why you are honoring me with this visit?”
+
+“You have not yet answered my own question,” observed Cole, quickly
+rallying to the verbal fencing match. “Is Reeves a patient of yours?”
+
+The doctor lowered his gaze. His piercing eyes searched Cole’s face. A
+faint flash of white teeth showed between the bearded lips.
+
+“I believe that question has a point to it,” he observed. “You ought to
+know, Mr. Stone, that a physician never discusses his patients. It is
+a very good rule, especially in the present instance. It affords me a
+good excuse for not answering your question.”
+
+“Then you admit you found the question embarrassing?”
+
+“A discreet man never admits anything, Mr. Stone. I may point out,
+however, that questions are never embarrassing, although answers
+sometimes are. I believe Wilde says something to that effect in one of
+his plays.”
+
+“Then you positively decline to answer?”
+
+“In order to spare us mutual embarrassment, yes. You see, Mr. Stone,
+there are circumstances in which a truthful answer may convey an
+erroneous impression. Now, won’t you tell me to what I owe the honor of
+this visit?”
+
+“Is that a candid question, Doctor Latham?”
+
+“By no means, my friend. I knew the answer before I spoke the question.
+I was merely curious to see whether you would reply truthfully.”
+
+Cole smiled. It was evident that Doctor Latham was a past master in the
+art of dueling with words. The man’s frankness amazed him. In admitting
+that he knew the purpose of Cole’s visit he had also admitted that he
+knew something about Malcolm Reeves’ condition. But he had turned his
+phrases so adroitly that nothing of a tangible nature could be fastened
+on him.
+
+“Will you tell me how you knew, doctor?”
+
+“Through a process of elimination. I knew at first glance that your
+concern over your physical condition was only a subterfuge. That
+narrowed the range of speculation down considerably. In fact, it left
+only one possible theory in regard to the object of your visit.”
+
+“Why only one? Isn’t it conceivable, for instance, that I came here to
+see if your office contains anything worth stealing?”
+
+Doctor Latham shook his head. “You don’t look the part, Mr. Stone.”
+
+“Well, suppose I am an officer of the law and came here to see if you
+are prescribing illegal amounts of intoxicating liquor or habit-forming
+drugs?”
+
+“You didn’t go about it the right way.”
+
+“Couldn’t I be a long-lost friend or relative?”
+
+“I haven’t either. You came here for one specific purpose, Mr. Stone,
+and I know what that purpose is.”
+
+Cole regarded him narrowly. “Knowledge sometimes implies guilt,” he
+remarked in casual tones.
+
+“But not always. You think that, because I know the object of your
+visit, I have guilty knowledge of a certain matter that you are
+interested in. That’s a very loose inference, Mr. Stone.”
+
+Cole thought for a few moments. The other’s indirect frankness amazed
+him, yet Doctor Latham was entirely too slippery to permit himself to
+be pinned down to hard facts.
+
+“Each of us seems to have come to stalemate,” observed the physician
+after a pause. “Shall we call the game a draw? Both of us have gained
+something. You think you have verified a suspicion, while I have
+learned to be on my guard against a new source of possible danger. Why
+not leave well enough alone?”
+
+“It’s a good suggestion,” said Cole, smiling. “Thanks for a very
+interesting half hour, doctor. Good day.” He bowed and moved toward the
+door, but the doctor’s voice made him turn back.
+
+“Just one moment, Mr. Stone. I think you have forgotten something. My
+fee is ten dollars. Ah, thank you!”
+
+
+
+
+ CHAPTER VII
+
+ COLE RECEIVES A WARNING
+
+
+He left the physician’s office a poorer, but a wiser, man. The half
+hour had been well spent even though the interview had yielded little
+in the way of tangible results. Cole had met an interesting personality
+and come in contact with a fine-edged mind. The doctor, with his
+subtleties and his evasions, had proven a fascinating character. His
+depth and elusiveness carried a teasing appeal to Cole’s imagination.
+Cole was not yet through with Doctor Latham.
+
+He walked to the corner, turned into a tobacconist’s shop, and bought
+a package of cigarettes, then stood at the curb and smoked one, while
+he glanced now and then at the physician’s house. The drab brownstone
+façade seemed as mocking and tantalizing as the man who dwelt within.
+It was as baffling and impenetrable as the doctor himself. Cole tried
+to analyze his impressions, but it was a hard task. The physician had
+admitted nothing except by implication. He had thrown out certain bold
+hints, and then he had practically challenged Cole to make the most of
+them.
+
+Cole did not like to draw hasty conclusions, but, after he had sifted
+down his impressions, there remained in his mind a picture of a
+polished and very artful rogue who performed his machinations with an
+adroit touch and a high degree of finesse. The picture was blurred
+in spots, and he had to use his imagination to touch up the obscure
+parts. It was significant, however, that the surgeon’s make-up should
+have exerted such a startling effect on Malcolm Reeves the night
+before. Beyond doubt Reeves had thought that he recognized the man who
+was responsible for his pitiful state. This proved inferentially Doctor
+Latham was the man who——
+
+But Cole did not like to deal in inferences. They were treacherous
+things, as he had observed on numerous occasions. He must have more
+facts before he began building up theories on the flimsy foundation
+which Doctor Latham’s oily innuendos had created in his mind. Meanwhile
+it was interesting to note that the clew which he had brought with him
+from the circular table appeared to be a substantial one. He had not
+convinced himself of Doctor Latham’s guilt, but he had at least found
+a promising lead. Reluctantly, for his experience of the night before
+still rankled, he was forced to admit that there was a modicum of truth
+in what the spokesman had told him.
+
+He finished his cigarette and was about to turn away, but just then a
+figure, rounding the opposite corner, claimed his attention. With a
+little start he recognized Professor Carmody. Bending over a stout cane
+the professor walked with a jerky gait and the plopping sound of shoes
+several sizes too large. He wore a sun-bleached silk hat and, despite
+the balmy autumn weather, a long overcoat covered his gaunt form.
+Cole nodded in a knowing way as he saw the professor turn into Doctor
+Latham’s house.
+
+Thoughtfully he walked away. His suspicions and speculations were
+assuming tangible form. Professor Carmody’s visit to Latham’s house
+in broad daylight suggested several things. Viewed in connection with
+certain other circumstances, it hinted strongly at a bond of interest
+between the two men. In view of what Cole already knew it seemed not
+so very far-fetched to suppose that they were associates in some
+enterprise that was more or less closely related to Malcolm Reeves’
+fate. That Carmody should openly call on the doctor seemed to indicate
+that the conspirators felt that they had covered their tracks so
+carefully that ordinary precautions could be thrown to the wind.
+
+Cole cut through a corner of the park, and gradually his perplexities
+dissipated themselves in the soft autumnal haze that hung over the
+greenery. He knew how to loaf as well as to work, and he possessed the
+happy knack of forgetting his problems in contemplation of rippling
+waters, or an azure sky. It was thus he conserved his energies and kept
+in touch with the softer aspects of life.
+
+He rested for half an hour, and then he remembered he had a duty to
+perform. It was not a pleasant task, but it must be done. Now that
+he had learned something definite about Malcolm Reeves’ fate, it was
+necessary that he should report progress to his clients. As he retraced
+his steps across the park and turned north on Fifth Avenue he wondered
+how much it would be advisable to tell. To go into details in regard
+to his adventures of the previous night would be impossible, for Cole
+himself did not know what they meant.
+
+Ascending the steps of a square-cornered house of gloomy aspect he rang
+the doorbell. There was a tomblike air about the residence of Hector
+Englebreth that gave Cole a chill each time he visited the house. Out
+of deference to the whims of the invalid who occupied it the window
+shades were nearly always lowered. Doors turned without the faintest
+sound on well-oiled hinges. Heavy carpets muffled the footfalls of
+inmates and visitors. The heavily shaded lamps threw a subdued light on
+massive and somberly upholstered furniture that seemed to belong to a
+remote past.
+
+A tight-lipped manservant ushered Cole into the library. Englebreth
+was seated in a wheel chair before a desk of black walnut. Despite the
+infirmity, which an acute case of inflammatory rheumatism had brought
+him, his long and triangular face gave an impression of wiry strength.
+His shoulders, as he sat hunched in the wheel chair, seemed uncommonly
+broad. His face was bloodless; his short-cropped, upstanding hair was
+almost white. Except when he spoke, the long, thin lips were tightly
+compressed, making him look as though he were constantly exerting his
+will power to hide the signs of his suffering.
+
+“Any news, Mr. Cole?” he inquired in a low, toneless voice.
+
+“I have made some progress,” replied Cole, also speaking in subdued
+tones. In that dim, somber room it seemed natural to speak softly. “I
+have reason to believe that your brother-in-law is still alive.”
+
+Englebreth had been tapping the desk with a pencil. Suddenly the
+tapping stopped. He gazed fixedly at the detective. “How much reason?”
+he asked.
+
+“I know it to be a fact,” said Cole, weighing his words, “that Mr.
+Reeves was alive last night.”
+
+“So,” mumbled the other in tones scarcely above a whisper. “Professor
+Carmody hasn’t done away with him, then. I feared that he might——” He
+broke off, then raised his voice a little. “How do you know this, Mr.
+Cole? How can you be so positive that my brother-in-law was alive last
+night? You don’t mean to say that you have seen him?”
+
+The last sentence was spoken in tense and vibrant tones, so unlike
+Englebreth’s usually colorless voice.
+
+“Before I answer that question,” said Cole, “I want to ask you one.
+What makes you so positive that Professor Carmody has had a hand in
+your brother-in-law’s disappearance?”
+
+“Have you learned something that has brought you to a contrary view?”
+
+“Please answer my question.”
+
+A scowl darkened Englebreth’s face. He resumed his slow tapping with
+the pencil. “We know that my brother-in-law had frequent and secret
+meetings with Carmody. We have established definitely that he had an
+appointment with the professor on the night of his disappearance.
+One of the servants in his house heard him make the appointment over
+the telephone. You yourself learned, from the delicatessen keeper
+across the street from Carmody’s place, that a man answering Malcolm’s
+description entered the house on that particular night. Fairly
+conclusive, I should say.”
+
+Cole eyed him levelly. “You are holding something back, Mr. Englebreth.
+You have not stated your principal reason for suspecting Carmody in
+connection with Mr. Reeves’ disappearance.”
+
+The tapping became a furious tattoo. “Why do you say that, sir?”
+
+Cole fumbled for words, then laughed. “I’ll be hanged if I know! It’s
+nothing but a hunch. From the first I had a feeling that you were not
+telling me all, but I admit I had no sound reason for thinking so.”
+
+Englebreth, seemingly mollified, smiled. “You detectives are suspicious
+of everybody. I suppose that’s a part of your stock in trade. However,
+I don’t mind admitting that, in this instance, you were partly right.
+I have told you everything that can be of any help to you in your
+search for Malcolm; yet there are certain trifling details that, for
+private reasons and out of regard for the family, I have not confided
+to you. You would not be interested in them, and they couldn’t be of
+any possible use to you. It was because of these private and delicate
+matters that I took the case to you instead of the police. Now will you
+answer my question? Have you seen Malcolm?”
+
+“I have, Mr. Englebreth. I saw him last night.”
+
+“Where?” The invalid strained forward in his chair. “In Professor
+Carmody’s house?”
+
+“No; I have not yet seen the inside of the professor’s residence.”
+
+“Then where did you see him?” The tapping had ceased again, and
+Englebreth was waiting breathlessly for the answer.
+
+“That’s the queer part of it.” Cole gave a little baffled laugh. “I
+have seen your brother-in-law, but I can’t tell you where.”
+
+“You can’t?”
+
+“Because I don’t know.”
+
+A threatening look crossed Englebreth’s face. “This is no occasion
+for jests, Mr. Cole. Even if you have no feelings of your own in the
+matter, you ought to respect the sentiments of other people. My wife is
+deeply shocked over the uncertainty regarding her brother’s fate.”
+
+“Pardon me, Mr. Englebreth. I laughed, but it was only out of sheer
+bewilderment. I had an experience last night that was so unbelievable
+that I shan’t try to describe it. I feel dazed whenever I look back
+upon it. All I can tell you is that I saw Mr. Reeves alive.”
+
+“And well?” questioned Englebreth sharply.
+
+“He seemed to have been through a trying experience.”
+
+“You are quibbling. I want the truth.”
+
+“Perhaps I shall be able to give it to you some time within the next
+twenty-four hours. For the present I fear you will have to be satisfied
+with what I have told you. My impressions of what I saw and heard last
+night are not very clear. You will understand the reason when I give
+you a full report.”
+
+“This is strange talk, Mr. Cole.”
+
+“Not half so strange as some of the things that happened to me last
+night.”
+
+Englebreth sat erect in his chair, regarding the detective with a
+piercing gaze. Evidently he was far from satisfied, and Cole could not
+blame him. Silence fell between them; then a soft tinkling was heard.
+Even the telephone seemed to utter its summons in whispers in that
+house of subdued sounds.
+
+The invalid wheeled his chair a little closer to the desk and put the
+receiver to his ear. A conversation ensued, and gradually Englebreth’s
+face underwent a transformation. Cole could not interpret the new look
+that came into his countenance, but he watched it in wonder. In a few
+minutes the invalid hung up, and the puzzling expression left his face
+as suddenly as it had come. He was smiling when he turned to Cole.
+
+“On the whole I find your report quite satisfactory,” he said in
+conciliating tones. “I appreciate the difficulties you have to deal
+with. Don’t mind me if I seem impatient. May I expect to hear from you
+soon again?”
+
+“To-morrow, I hope.” Cole was still marveling at the change he had
+witnessed in his client. He wondered whether the telephone conversation
+had brought it about. From Englebreth’s part in it he had been unable
+to make out its nature, but he imagined that his client had received
+news of a startling kind. After an exchange of a few casual remarks he
+got up and moved toward the door.
+
+“Just one thing more, Mr. Cole,” said Englebreth as he placed his hand
+on the knob. “Please be careful.”
+
+“What?” Cole turned and looked back at the invalid. The tone, rather
+than the words, had given him an odd sensation. Englebreth’s white face
+was wreathed in smiles, but Cole sensed a hidden barb somewhere.
+
+“Just be careful,” said the invalid. “That’s all, Mr. Cole.”
+
+Cole went out, but echoes of Englebreth’s voice pursued him through
+the door and out on the street. The words had sounded as though they
+contained a veiled threat of some kind. What could he have meant? He
+turned the question over in his mind, time and again. Was it possible
+that Englebreth, in some strange and devious way, had learned of the
+attempt that had been made to persuade Cole to betray his client?
+
+The theory seemed grossly improbable, but, as he walked along, he
+could think of no other solution. The more he thought of it the more
+likely it seemed that his client had, in some mysterious manner, got
+an inkling of last night’s happenings. He remembered the agitation he
+had shown at the telephone. And later, when he gave Cole that peculiar
+warning, his voice had sounded as though he meant to convey a threat of
+terrible punishment if the detective should go back on his duty.
+
+Cole had not walked far when his step began to lag. He paused at a
+corner and glanced at his watch. He pursed his lips, then he scowled a
+little, and a look of weighty responsibility came into his face.
+
+It was time to go home and feed Toots.
+
+
+
+
+ CHAPTER VIII
+
+ THE UNKNOWN SEVEN
+
+
+All evening Cole had felt a presentiment that his telephone was to
+ring. When it finally did ring, shortly after eleven o’clock, he knew,
+even before he lifted the receiver from the hook, that he was about to
+receive a message from the mysterious seven.
+
+His “hello” was answered by the rich soprano voice of the woman who
+called herself Miss Brown, but somehow it sounded different. The
+frolicsome undertone, which he had noticed the previous evening, was
+gone. In place of it there was a faint tremor that hinted of keen
+anxiety.
+
+“I am calling from a public booth near Madison Square,” she told
+him. “At exactly twelve o’clock I shall be waiting in my car, on the
+southeast corner of Broadway and Twenty-third Street.”
+
+“I’ll be there,” said Cole firmly. During the late afternoon and
+evening he had made up his mind that, if a summons should come from the
+mysterious seven, he would obey it.
+
+“But be careful,” she went on, and the last word had an oddly familiar
+sound in Cole’s ears. “An attempt will be made to follow you.”
+
+“I know,” said Cole lightly. “I’ve been watched ever since I went out
+to dinner this evening. I believe somebody is looking up at my windows
+this very moment. Have no fear. I’ll shake him off.”
+
+Again requesting him to be careful, Miss Brown rang off. For a moment,
+after the connection had been severed, he stood smiling into the
+transmitter. Then he stepped to the window and looked out into Gramercy
+Park. The sky was partly overcast, and a haze of moonlight and shadows
+hovered over the trees. Almost directly below his window stood a gaunt
+individual whose eyes were slanting up at him beneath the brim of a
+dark felt hat.
+
+Cole examined his pistol before he put it in his pocket, donned hat and
+light overcoat, and went out. On the stoop he paused for a moment and
+stuck a cigarette between his lips. Then he swung down the steps and
+sauntered up to the watcher at the curb.
+
+“Pardon,” he said urbanely. “Could I trouble you for a match?”
+
+The watcher searched his vest pocket and handed him one. Cole caught
+a full view of the fellow’s face as he kindled his cigarette. The man
+was a stranger to him. Murmuring profuse thanks for the accommodation
+Cole walked away. Twenty minutes later, after a devious journey by
+foot, subway, and surface cars, he plunged into the traffic jam in the
+theatrical district. For a little while he darted in and out among
+surging streams of humanity. Then, certain that he had thrown the
+pursuer off his tracks, he boarded a southbound car. A tower clock was
+signaling the midnight hour just as he reached the appointed corner in
+Madison Square.
+
+“You are very prompt,” observed Miss Brown, as he stepped into the
+limousine in which his adventure had begun, exactly twenty-four hours
+ago. “You are sure you haven’t been followed?”
+
+“Only a short distance.” Cole sat down beside her, having a weird
+feeling that ages had passed since he last touched those cushions. “I
+shook off the fellow quite easily.”
+
+The car was gliding swiftly toward the south, but soon it began to turn
+and twist in all directions. The windows were shaded, and Cole could
+only guess which way they were going.
+
+“You’re an audacious person,” murmured the girl. “After what happened
+last night I wasn’t sure you would come with me a second time.”
+
+Cole smiled. “Audacious isn’t quite the word.”
+
+“No, I suppose not. You’re not the kind of man who indulges in foolish
+bravado. Your decision to come with me to-night was the result of long
+and careful thinking, after you left Doctor Latham’s office. Your
+interview with the doctor convinced you that our acquaintance might
+be worth cultivating, despite the rough treatment you were given last
+night. Am I right?”
+
+“In the main. You know, then, that I called on Doctor Latham?”
+
+“Of course. You have been under constant surveillance since you left
+our establishment early this morning.”
+
+“How flattering! But you puzzle me, Miss Brown. I have been conscious
+of being watched only since dinner time.”
+
+She gave an amused laugh. “One is never conscious of our brand of
+espionage. We have men on our staff who have reduced shadowing to a
+fine art. They are not so easily shaken off as was the simpleton who
+stood outside your windows this evening. By the way, Mr. Cole, aren’t
+you harboring a little resentment against me for my part in last
+night’s affair?”
+
+“Perhaps,” said Cole dryly, “but curiosity is a stronger motive than
+resentment.”
+
+“You are not at all gallant. Lots of other men would have replied to
+that question with a flowery compliment.”
+
+“They would have been fools. You would have secretly despised them for
+it.”
+
+A little pause. “Thank you,” she whispered, but the words sounded so
+faint that Cole was not sure he was expected to hear them.
+
+The car had ceased its zigzagging course and was traveling in a
+straight line. Presently Miss Brown produced the scarf with which she
+had covered his eyes the previous night.
+
+“I hope this is the last time I shall have to blindfold you,” she
+murmured, as she folded the cloth into a bandage and covered the upper
+portion of his face. “Perhaps the next time——”
+
+She did not finish the sentence. Just then the car stopped, and she
+guided him across the sidewalk and up the stone steps. In a few moments
+they were darting upward in the elevator. Again the wall opened at Miss
+Brown’s touch on a hidden spring. As it closed behind them Cole had
+a hazy feeling of being shut off from the world. They walked a short
+distance down the corridor. Then a door opened, and once more he found
+himself in the room with the circular table. The girl vanished, and a
+voice bade him step forward.
+
+He walked up to the table. The masked men seated around it looked gray
+and ghostly in the dusk. He scanned the veiled faces closely as his
+eyes responded to the dim light. The black beard was not there; yet he
+counted seven faces. Evidently the surgeon was not wearing his disguise
+to-night.
+
+“Very glad to see you, Mr. Cole,” said a voice which he recognized.
+“The fact that you have returned is additional proof that we were not
+mistaken in you. Sit down.”
+
+Cole seated himself at the spokesman’s side. His ears were keyed to
+catch any suspicious sound, while his eyes cautiously explored the dusk
+about him. His right hand hung loosely over the side of the chair, but
+it was ready to reach for his pistol at the slightest sign of danger.
+He was far from certain in regard to the intentions of the seven men,
+and he was determined not to be caught off his guard.
+
+“Perhaps it will give you some satisfaction to know,” the spokesman
+went on, “that you sent one of our men to the hospital last night.”
+
+Cole smiled faintly as he recalled the fight in the dark. His knuckles
+still showed bruises from the blows he had showered on his opponent
+before he was overwhelmed by superior numbers.
+
+“He is a big, husky chap, and he knows how to put a lot of steam into
+his punch,” the spokesman continued. “You pounded his face to a jelly.
+I don’t think Sam will ever get over the humiliation. His mortification
+ought to soften the bitterness you naturally feel toward us. By the
+way, you called on Doctor Latham, as I suggested. Did the interview
+prove satisfactory?”
+
+“It wasn’t conclusive,” said Cole guardedly.
+
+“We didn’t expect that. The doctor is too wily to permit himself to
+be caught so easily. But didn’t your talk with him leave a strong
+presumption of guilt in your mind?”
+
+“It convinced me that Doctor Latham knows something of what happened to
+Mr. Reeves.”
+
+“And to that extent it modified your skepticism in regard to us?”
+
+“I am here,” said Cole with a shrug. “Isn’t that answer enough?”
+
+“It is. You wouldn’t have come back to-night unless something had
+happened to counteract the bad impression which you derived from your
+first visit. No doubt the balance is still against us, but you are
+willing to listen to what we have to say. Will you pay close attention
+while I state a hypothetical case?”
+
+“My ears are wide open.”
+
+“Very well, then. First let me state a general principle. It must have
+occurred to you, Mr. Cole, that there is something radically wrong with
+the enforcement of our laws and the administration of justice. The
+jails are doing a thriving business, and many criminals are convicted
+every day in the year. With rare exceptions, however, they are the
+smaller fry. Too often the big rascals go unpunished, while the little
+fellows get it in the neck. The agencies of law and order are often
+powerless when dealing with criminals who perpetrate their malefactions
+on a large scale. Are you with me so far?”
+
+“Go on,” said Cole.
+
+“The cause of this deplorable situation is obvious. The big rascal
+evades the law and goes scot-free, while the little fellow breaks the
+law and lands in jail. Or else the big rascal violates the law in such
+a clever manner that conviction is impossible. He has the best legal
+talent on his side. Brilliant and unscrupulous lawyers lie awake nights
+scheming how a powerful client might commit crimes with impunity. Often
+the big rogue has unlimited resources at his command. If he is in
+danger of getting caught a substantial bribe frequently lets him out,
+or he uses political or social influence to get clear of the danger.
+True, isn’t it?”
+
+“Unfortunately it is,” said Cole, “but I don’t see what all this——”
+
+“Just a moment. I am getting to the point as fast as I can. You
+must have noticed that the police and other agencies are seriously
+handicapped in trying to cope with crime on a large scale. They are
+hampered by a number of things, inefficiency, corruption, political
+patronage, sometimes indifference on the part of the public. There are
+many honest and capable men among them, but their number is too small.
+Besides, the machinery of justice is too ponderous and cumbersome. In
+its competition with crime it has the same handicap as a truck trying
+to compete with a roadster. But that isn’t the worst of it.”
+
+“You’re painting a gloomy picture,” Cole observed.
+
+“But you know as well as I do that it is true to life. The most serious
+phase of the situation is the fact that the law, in effect if not
+in theory, is punitive rather than preventive. Our administrators
+of justice are too often content with locking the stable after the
+horse is gone. It may be a satisfaction to you, when your pocketbook
+is stolen and the money squandered, to see the thief go to jail, but
+it isn’t doing you any material good. It may be gratifying to you to
+know that that particular thief won’t steal any more pocketbooks for a
+while, but that isn’t going to compensate you for your loss. The time
+to stop the crook is before the damage is done, and that’s exactly
+where our police system falls down on the job.”
+
+“True enough,” Cole admitted. “But what are you going to do about it?”
+
+He fancied the spokesman was smiling, but he could not be sure. The
+others at the table had not spoken a word.
+
+“There is the Carmody case, for instance,” the other went on, without
+answering Cole’s question directly. “It shouldn’t be called that, for
+the professor is only a puppet, a dwarf in comparison with the men who
+are pulling the strings. You have barely scratched the surface of the
+case, so, no doubt, you are amazed at what I say. The so-called Carmody
+case is in reality one of the biggest swindles ever projected. It is
+being engineered by a group of brilliant and very powerful men who have
+enormous resources in brains and cash at the tips of their fingers.
+They are working in the dark, with the utmost secrecy and astounding
+cleverness. If the authorities at Washington knew what was going on,
+there would be a panic all along Pennsylvania Avenue.”
+
+“Why doesn’t some one tell them?”
+
+The spokesman chuckled deprecatingly. “If I should go to them with the
+story to-morrow they would demand proof, and I haven’t any. That is,
+nothing that is tangible. I am positive of my facts, but proving them
+is another matter. In a case like this the proof can’t be produced
+until the damage is already done. Having no evidence, I should probably
+be met with indifference or skepticism. Even if an investigation were
+made, it would be purely perfunctory. The investigators would kick up
+just enough dust to blind themselves and tip the conspirators off to
+their danger.”
+
+“But, if things are as bad as you say, something should be done.”
+
+“Something is being done, Mr. Cole, and that brings me to the
+hypothetical case I was about to state. Imagine a group of wealthy
+and public-spirited citizens, men of brains, aggressiveness, and
+imagination, who have banded themselves together for the purpose of
+correcting the condition I have just described. Let us say they have
+built up a small, compact and marvelously efficient organization, in
+comparison with which the government’s ponderous machinery is like
+the truck trying to out-distance the roadster. This organization,
+unhampered by graft, political patronage, and red tape, and having
+unlimited resources at its command, becomes the secret ally of the
+police, the department of justice, and similar agencies. Its existence
+is practically unknown to all but its own members. Like the criminal
+whom it is endeavoring to combat, it works in the dark and silently.
+This in itself gives it a tremendous advantage. You are beginning to
+understand?”
+
+Cole nodded.
+
+“This organization has a corps of brilliant operatives, each one tested
+and tried and found one hundred per cent honest and efficient. At its
+head is an executive of exceptional ability. All the resources of the
+organization are placed at his disposal. He is paid a salary so large
+that it should render him immune to all sorts of corruption and amply
+compensate him for the fact that his achievements never become known to
+the outside world.”
+
+“For a time all goes well. Now and then the police, or the authorities
+at Washington, receive a package from an anonymous source. They open
+it and dazedly peruse the contents. It is evidence gathered by some of
+the shrewdest detectives in the country and put into shape by the best
+lawyers obtainable. It is so thoroughly prepared that it will stand
+every legal test. All the authorities have to do is to hale the culprit
+into court and read the evidence to the jury. In all cases but one the
+verdict has been guilty.”
+
+“The exception,” the spokesman went on in gritty tones, “was due to
+the dereliction of the executive at the head of the corps. Contrary to
+expectations and despite all the incentives which he had for remaining
+loyal to the organization, the man was corrupted by the other side. No
+doubt he sold his honor for a fortune. At all events he disappeared,
+and the case collapsed. It was necessary to find some one to take
+his place. This time the men at the head of the organization were
+determined to make no mistake. The next executive must be not only
+efficient and fearless, but incorruptible as well. For once the leaders
+decided to let the ends justify the means and go the limit in testing
+their candidate. Well, they did go the limit. They tried him in acid,
+and he assayed twenty-four carats.”
+
+Murmurs of approval went around the circle. Every face was leveled
+intently in Cole’s direction. For several minutes he had anticipated
+the trend of the spokesman’s remarks, yet he started a little at the
+last sentence.
+
+“Now you understand,” the other continued. “For some time we have been
+satisfied in regard to your ability. Our secret investigation left
+us in no doubt on that point. Last night we learned that you could
+resist three of the most powerful forms of temptation imaginable—fear,
+greed, and a charming woman’s tears. And not only that, but you also
+proved your superiority in a physical encounter, in addition to showing
+presence of mind and quickness of wit in a most terrifying situation.
+You scored one hundred per cent on every point. I am only sorry the
+test had to be so severe.”
+
+Cole sat silent for a time; then he shook the spokesman’s outreached
+hand. “It’s worth a lot to me to know that I am a twenty-four-carat
+man,” he declared.
+
+“Then you accept?”
+
+Cole pondered while his glance swept the masked faces.
+
+“Who are you?” he asked.
+
+“We call ourselves The Unknown Seven. The name fits because nobody, not
+even our best friends, know us in our capacity of secret allies of the
+authorities. It’s possible you have seen some of us before.”
+
+He raised his arm, and each man at the table made a sudden motion
+with his hand. In an instant the seven masks had been removed. Then a
+glaring light shattered the dusk, and Cole looked in astonishment at
+the unveiled faces. Several of them were familiar to him from pictures
+that had appeared in the newspapers, in connection with weighty
+national or municipal affairs. He blinked his eyes in bewilderment and
+was about to say something when the door suddenly opened.
+
+Miss Brown entered in great haste. She was pale and breathless, and
+Cole could see that something of a startling nature had happened. The
+seven men rose and bowed as she came up to the table.
+
+“What is it?” asked the spokesman.
+
+For a moment the girl’s eyes rested on Cole’s face. There was a
+mingling of questioning, suspicion, and reproach in them that
+bewildered him. Then she turned to the spokesman. “The red light is
+flashing on the indicator!” she breathlessly declared. “Some one is
+coming up the elevator!”
+
+For a moment each man in the room stood rigidly still. Then came a
+shuffling of feet and scraping of chairs. Now and then an ominous
+mutter was heard. Then, with one accord, all glances turned
+threateningly in the direction where Cole stood.
+
+
+
+
+ CHAPTER IX
+
+ THE RED LIGHT
+
+
+For a time no one in the room moved. Cole was both amused and puzzled
+by the hostile glances leveled in his direction. The attitude of The
+Unknown Seven had changed from friendliness to suspicion, with an
+abruptness that was almost ludicrous. Miss Brown’s reference to a red
+light seemed to have turned them against him in a twinkling.
+
+He could not understand. He looked at the spokesman as if expecting an
+explanation. Now, with the lights on and the mask removed, Cole thought
+there was something familiar about his face. It was hewn on rather
+rough lines, suggestive of a man of great strength and determination.
+The iron-gray hair curled a little. The mouth was firm and gave a trace
+of harshness to the face. The eyes, arched by upslanting brows, were
+clear and cold.
+
+Just now those eyes were gazing fixedly at Cole. There was the faintest
+suspicion of a threat in them, he thought. He pondered for a moment,
+arranged a few scattered recollections, and then the man’s name came to
+him. He was Grover Carlin, a criminal lawyer of high standing and great
+ability. Cole had once heard him make a masterly address to a jury.
+
+Only a few moments had passed since Miss Brown had made her breathless
+announcement. Now one of the seven men sprang toward the door, and the
+others followed. Cole and Carlin, walking side by side, brought up the
+rear. The foremost of the procession opened a door across the hall, and
+the others tumbled in after him. It was a large room, filled with desks
+and filing cases, but the first thing that caught Cole’s eye was a
+globe of glass in which a red light was flashing at intervals of a few
+seconds.
+
+“What does it mean?” he asked Carlin.
+
+The lawyer gave him a sharp glance. “It means that a stranger is coming
+up the elevator,” he announced shortly.
+
+“Why a stranger? Couldn’t it be one of your own men?”
+
+“No. When our own men enter the private elevator they always throw a
+lever which prevents the light from flashing. The red light is a danger
+signal. The elevator is an automatic one, and it is impossible for a
+stranger to operate it unless he is acquainted with the mechanism. Our
+visitor must have got the hang of it, somehow. Mr. Cole, you are the
+only outsider who has been inside this establishment in weeks.”
+
+“Am I to infer that I am under suspicion?”
+
+“Well, it looks rather queer.”
+
+Smiling, Cole watched the flickering red in the glass globe. “But you
+admitted yourself that I am a twenty-four-carat man.”
+
+The other nodded. “Yes, I know, but——”
+
+“Perhaps you suspect I arranged to have myself followed here this
+evening?”
+
+“Such a thing is conceivable.”
+
+“But the rest isn’t very practicable. I never saw the elevator, much
+less learned how to operate it. I was blindfolded both times I came up
+in it.”
+
+“True, but you are a very clever man, Mr. Cole. Your performance of
+last night proved that. And the fact remains that you are the only
+stranger who has been inside this establishment in a long time.”
+
+The red flashes had ceased. Cole looked about him. Several of the men
+were glowering at him, while Miss Brown regarded him with a look of
+doubt and vague disappointment.
+
+“What about the former executive you mentioned, the man who betrayed
+you?” he asked. “Isn’t it possible that he is up to deviltry of some
+kind?”
+
+Carlin shook his head. “The mechanism has been changed since he left
+us. Besides, he would know enough to turn the lever to prevent the
+light from flashing. It will be interesting to see whether our visitor
+knows how to operate the sliding panel in the wall. If he does, you
+will presently see a green light in the indicator.”
+
+It was evident that the lawyer was trying to be fair and withhold
+judgment, but Cole could see he was an object of grave doubt. The
+others in the room were intently watching the indicator, but now and
+then they glanced darkly at Cole. Several of them seemed loath to
+suspect him, and among them was Miss Brown; but apparently they could
+think of no other explanation for the mysterious intrusion than that he
+had played false with them.
+
+Like the others he fell to watching the glass globe. The ceasing of
+the red flashes seemed to indicate that the intruder had reached the
+top floor. Perhaps at this very moment he was searching for the hidden
+spring that controlled the panel in the wall. Cole felt a tingling
+suspense as he waited to see whether a green light would appear in the
+indicator.
+
+“What can the fellow hope to gain by coming here?” he asked Carlin.
+
+The lawyer gave him a searching glance, as if not quite sure that the
+question had been asked sincerely. “A lot,” he said dryly. “There
+are papers in our files, evidence in the form of memoranda and legal
+documents, that certain parties would be willing to pay a great price
+for.”
+
+“But doesn’t he realize that you won’t give them up without a fight?”
+
+“Usually only the watchmen are here as late as this.” The lawyer gave
+Cole another dubious glance out of his cold eyes. “To-night and last
+night we have been holding special sessions on your account. Probably
+our unbidden visitor doesn’t know that. If he is hoping that he will
+have only a couple of watchmen to deal with, there will be a surprise
+waiting for him as soon as he gets through the wall, if he does get
+through.”
+
+Evidently the intruder was having difficulties. For several minutes the
+indicator had been blank, but the glances of those in the room were
+drawn to it as to a magnet.
+
+Cole’s eyes traveled over the oddly assorted company. A few feet in
+front of him stood a retired financier, a multimillionaire, who had
+once been a power in Wall Street, and whose money was being used
+unsparingly to fight corruption and vice. A little to one side was a
+philanthropist whose annual benefactions mounted into eight figures.
+Three or four of them were strangers to him, and among these was the
+surgeon, whose tall figure Cole easily recognized despite the fact that
+he had worn a disguise on the other occasions.
+
+His mind was active while he studied the faces about him. Would the
+green light flash on the indicator? Who was the intruder, and was
+Carlin right in the surmise that the documents in the filing cases
+were the object of the mysterious visit? For a thief to sneak into an
+establishment of this kind looked like a piece of foolhardy daring
+to Cole. There were nine of them in the room, including Miss Brown
+and himself, and no doubt agents and operatives of The Unknown Seven
+were within calling distance. There was a lively tussle ahead of the
+prowler, if he should succeed in getting through the wall.
+
+Ten minutes had passed since the red flashes stopped. Cole was
+beginning to think that the intruder had met insuperable obstacles.
+Perhaps he had in some manner learned how to operate the elevator, but
+had failed to familiarize himself with the mechanism that controlled
+the sliding panel in the wall. All the while, as these speculations ran
+through Cole’s mind, he felt that Carlin was watching him out of the
+tail of an eye.
+
+“Aren’t you a bit hasty in turning to me with your suspicions?” he
+asked good-naturedly. “I may be a twenty-four-carat man, but I am not a
+worker of miracles, and I’d have to be one in order to ferret out your
+secrets on such short acquaintance. What about your hired agents?”
+
+“I trust them as I trust myself. They have been tested and found true.”
+
+Cole smiled engagingly. “Your experience with the renegade executive,
+whom you told me about, should have warned you that tests aren’t always
+conclusive. Human nature is about as uncertain as April weather.”
+
+Carlin gave an assenting nod, but the argument did not seem to
+influence him greatly.
+
+“How will you dispose of the rascal if he gets through?” was Cole’s
+next question.
+
+“That’s a problem. Our success so far has been due largely to the
+secrecy with which we have surrounded ourselves. We have nothing to
+fear, and no great harm would be done if we should be found out, but we
+prefer to continue to work in the dark. So far our absconding executive
+seems to have kept his mouth closed, for nothing has leaked out about
+us. No doubt he is so busy spending his thirty pieces of silver that
+he has no time for gabbling. Besides, the scoundrel has a wholesome
+respect for us. He knows that The Unknown Seven has a long arm and a
+sturdy fist. If this fellow,” with another glance at the indicator,
+“should get through the wall, we shall have to take measures to protect
+our privacy. If we find that he has the right stuff in him we may even
+invite him to join us.”
+
+Another five minutes passed. Some in the group showed signs of
+restiveness. One of them suggested going out and collaring the
+prowler, but Carlin vetoed the idea, declaring it would be better to
+give the fellow a chance to show his hand.
+
+The group resumed its silent waiting. A question occurred to Cole, one
+that he had been on the point of asking when Miss Brown’s entrance
+interrupted the conversation in the other room.
+
+“How is Mr. Reeves?” he inquired.
+
+Carlin waited for several moments before he answered. “There has been
+no change in his condition in the past twenty-four hours,” he finally
+announced.
+
+“He is still here?”
+
+The lawyer nodded. He did not seem very communicative on that subject.
+
+“You know, of course,” Cole went on, “that it isn’t in strict
+accordance with the law for you to keep him here?”
+
+A thin smile twisted Carlin’s lips, but his only response was a shrug.
+
+“My duty to my clients gives me an interest in the matter,” Cole
+pointed out. “You are keeping Mr. Reeves a prisoner.”
+
+“By no means. Mr. Reeves is our guest, and so far he has not voiced
+any objections.” He gave a grim chuckle. “Furthermore he is infinitely
+better off here than where we found him. He would probably have been
+dead by this time if we hadn’t taken him away.”
+
+“From where?”
+
+The lawyer’s wintry gaze rested for an instant on his face. “From the
+residence of Professor Carmody, as you probably either know or can
+readily guess.”
+
+“You kidnaped him?”
+
+“Call it that if you like. We saved Mr. Reeves from certain death.
+Professor Carmody is the only one who has cause for feeling aggrieved
+at what we have done.”
+
+Cole nodded thoughtfully. He had kept Carmody under observation for
+some time, and of late he had noticed a change in him. He understood
+now why the professor had seemed excited and ill at ease the last few
+days. His comings and goings had been more frequent and there had been
+several signs of something unusual on foot about the house on Bleecker
+Street.
+
+“So that you may feel quite reassured in the matter,” Carlin went on,
+“let me tell you that Mr. Reeves is under excellent care. A specialist
+is studying his condition, and there’s a chance, though a very remote
+one, that he may recover his mental faculties, wholly or in part. If he
+does, I fancy he will have a very entertaining story to tell.”
+
+He looked sharply at Cole just then, as if trying to measure the effect
+of his words, but Cole’s face showed nothing but deep thought. He had
+obtained a glimpse into the working methods of The Unknown Seven, and
+he had found fresh proof of the efficiency and the resources of the
+organization. A splitter of hairs might not have found its methods
+strictly legal, but there was such a thing as the end justifying
+the means. Quite likely Carlin was right in saying that Reeves had
+been rescued from certain death at the hands of Professor Carmody.
+Probably, too, a great deal more could be accomplished by this informal
+course of procedure than by strict adherence to the letter of the law.
+Cole was so deeply impressed that for the moment he forgot that he was
+under suspicion.
+
+“If Reeves ever tells his story, I’d like to be there,” he declared.
+
+“You may have an opportunity to do so,” dryly remarked the lawyer.
+“Until we have satisfied ourselves on one or two little points we shall
+have to ask you to remain here as our guest. In the meantime——”
+
+A medley of mutters and hushed exclamations interrupted him.
+Instinctively Cole glanced at the indicator. A tongue of green flame
+was shooting up and down in the glass globe. Fascinated, he watched the
+darting flashes.
+
+“Get back!” ordered Carlin, waving a hand at the men who stood huddled
+into a knot before the indicator. In his other hand gleamed the barrel
+of a pistol. Cole admired the ease and coolness with which he was
+taking charge of the situation. Following the direction of his pointing
+finger, the men crowded into a corner of the room. Miss Brown followed
+them, and, as she crossed the floor, she gave Cole a glance that
+stabbed within him.
+
+Carlin touched a button; the room went dark. Keeping Cole close at his
+side he took up a position a few feet in front of the others. “I must
+warn you not to move,” he whispered in Cole’s ear.
+
+“Have no fear,” Cole whispered back. “I’m as anxious to see this
+through as you can possibly be.”
+
+The lawyer’s strategy was simple. If the intruder’s aim was to get
+hold of some of the documents in the filing cases he would probably
+come straight to this room. The fact that he had mastered the mechanism
+of the elevator and the hidden door seemed to indicate that he was
+fairly well familiar with the lay of the establishment. Evidently the
+lawyer’s plan was to catch him red-handed and take him by surprise.
+
+Cole was conscious of a growing disquietude as he stood beside the
+lawyer, looking in the direction of the door through which the intruder
+must pass. He had a hazy feeling that Carlin’s plan was too simple, but
+he could not tell exactly what was wrong with it. Not a sound was heard
+in the room. The door had been left open a crack, and a narrow wedge of
+light filtered in, but most of the room was an impenetrable blur.
+
+A minute passed. In vain Cole strained his ears to catch the sound of
+approaching footsteps. His uneasiness grew, but he could not understand
+why. As if his misgivings had been communicated to the lawyer, the
+latter mumbled something under his breath. The moments flew, and still
+no sound was heard in the corridor. Either the intruder’s footfalls
+were thoroughly muffled, or else——
+
+Cole did not finish the thought. A vagrant suspicion held his senses
+spellbound. For a moment longer he listened for footfalls that did not
+come, and then his vague apprehensions crystallized in a flash. He
+gripped the lawyer’s arm so violently that Carlin gasped.
+
+“You were wrong!” he whispered hoarsely. “The fellow isn’t after any
+papers. He came here to get Reeves.”
+
+Cole, with his hand tightly gripping Carlin’s arm, felt a sudden shock
+shooting through the man at his side. In a twinkling the lawyer seemed
+to have grasped his meaning. Now, muttering something, he sprang
+forward. In an instant the lights were on again, and Carlin was running
+toward the door. Cole followed, but in a moment the two men came to a
+dead stop.
+
+A short, piercing cry sounded. It died abruptly, leaving a curious
+emptiness in the air. The two men stared at each other, and Cole saw a
+gray film creep over the lawyer’s face.
+
+“Too late!” he exclaimed.
+
+
+
+
+ CHAPTER X
+
+ PURSUIT
+
+
+The scream had ended with a certain grim abruptness that to the
+listeners could mean only one thing. It had seemed to stop in the
+middle; yet it had been punctuated with an ominous finality. It was as
+if death itself had stepped in and placed an exclamation point after an
+unfinished cry.
+
+Then came utter silence. It seemed as though every sound and every
+breath of life had been sucked out of the air. Carlin, his lips drawn
+apart at one side, looked fixedly at the door. His head, shoulders and
+chest were straining forward; he appeared to be maintaining his balance
+by sheer mental tension. A few moments passed, and then Cole shook
+himself free of the insidious horror that attacks even the strongest.
+Less than thirty seconds had elapsed since the cry sounded.
+
+“Where is he?” he asked, shaking the lawyer’s arm.
+
+“He?” Carlin seemed to be trying to shake off a spell. “Oh, Reeves, you
+mean. Back there.” He pointed indefinitely toward the corridor.
+
+“Brace up, man!” Cole shouted. “Go to him. Maybe something can be done.
+Hurry!”
+
+He bounded to the door and out in the hall. His words had voiced a hope
+that he did not feel. The cry had told him only too eloquently that
+Reeves was beyond help. But there might still be time to catch the
+murderer, if he made haste. Heedless of Carlin’s belated shout to him
+to stop, he hurried down the long and dimly-lighted corridor. Confused
+cries and scurrying footfalls sounded behind him, signifying that the
+others had come out of their temporary stupor.
+
+Cole shut his ears to the bedlam. All he saw and heard was a shadow
+darting toward the end of the hall and a patter of swift feet. At the
+farther end of the corridor, at the point where Miss Brown and himself
+had entered the headquarters of The Unknown Seven, was an opening. He
+came up to it just in time to see the fleeing shadow slip through.
+
+“Stop, or I’ll wing you!” he cried, jerking his pistol out of his hip
+pocket, but the fugitive paid no heed. Crouching low, he ran with
+zigzagging motions across the open space toward the elevator shaft.
+Cole aimed low and pulled the trigger. The bullet thudded against the
+flagged flooring, and through the smoke he saw the fugitive spring into
+the cage. Already the door was clanking shut. He plunged forward and
+kicked his foot into the opening, just in time to stop the sliding door
+from closing. He caught a glimpse of a stiff felt hat, a sallow face
+with a mocking grin, a lean and slightly hunchbacked figure, and then
+the cage shot downward.
+
+Cole, standing with his right foot caught between the door and the
+steel jamb, muttered a malediction, but it was aimed mostly at himself.
+The little hunchback had eluded him with an agility that aroused his
+admiration, even while it made him grit his teeth. He flung the
+door wide open. Only a few moments had passed since the cage started
+downward, and it had not got far. There was something tantalizing about
+the swiftness with which it increased the distance between himself and
+the fleeing man.
+
+For a moment Cole gauged his chances. He gazed at two sets of cables
+that glided up and down inside the shaft. His next move would have
+seemed foolhardy to an onlooker, but Cole had carefully measured the
+risk. It was one of those tense moments in which the mind leaps quickly
+to decisions. The time it took him to determine what to do was only a
+matter of seconds.
+
+He flexed his muscles and then he leaped. For an instant his form
+hurtled through space, then his hands closed tightly around the
+downward gliding cable. He wound his legs about it and clamped it
+between his feet. The swift descent made him feel as if he were sucking
+ice-cold air into his lungs. The cage, some twenty-five or thirty feet
+below, was dropping like a rock, but now Cole was following at an equal
+rate of progress.
+
+Ten floors slipped past, then fifteen, finally twenty. Cole’s hands
+were raw and bleeding. Hot and cold flashes were chasing up and down
+his back. His lungs were straining, and a treacherous numbness was
+creeping into his limbs. He looked down at the roof of the cage and
+smiled. No doubt the fleeing man felt that his escape was already as
+good as accomplished.
+
+The cage stopped so suddenly that the vibration of the cable almost
+made Cole lose his hold. He slipped a little farther down, then
+checked his descent opposite the level of the second floor. The shaft
+was narrow, and he could easily reach the door with one hand, while he
+clung to the cable with the other. Installed for private and secret
+use the elevator equipment lacked several safety devices that would
+have acted as a hindrance to Cole. As it was the door slid open easily.
+Seizing the jamb with one hand he swung free of the cable and landed on
+the floor.
+
+He felt a trifle dizzy, but the thrill of pursuit acted as a stimulant.
+Just around the shaft was a stairway, and he hurried down. Only a few
+moments ago a metallic clanking had signified that the fugitive was
+getting out of the cage. As Cole reached the lower steps he saw a long
+open space in front of him, and at its farther end he caught a glimpse
+of the hunchback, slipping out through the door. His ears caught
+the sound of throbbing motors, warning him that a car was waiting
+outside to speed the fugitive to safety. Conscious of nothing but the
+exhilaration of the hunter he bounded to the door and emerged on the
+sidewalk, just as a tail light gave him a mocking wink and disappeared
+around the corner.
+
+There was a fine mist in the air. On all sides the tops of the tall
+office buildings reared their heads in a translucent haze. The streets,
+which in the daytime swarmed with humanity, were now deserted. Cole
+guessed that it must be about two o’clock, but he did not take time to
+look at his watch. The taunt of the tail light egged him on. He threw
+his head back and his chest out and broke into a sprint. Rounding the
+corner at full speed he once more caught a glimpse of the jeering tail
+light. But it was only a glimpse, for a moment later it was out of
+sight.
+
+Cole tried to run faster, but he realized that, unless something
+unforeseen happened, he was running a losing race. The car had the
+advantage in speed and endurance. With scarcely a stop, save for the
+possible interference of a traffic officer, it might travel all the way
+from one end of Manhattan to the other. He kept up the pursuit only
+because he hated to cry quits. Besides, as long as he could continue
+the chase, there was always the possibility that chance might come to
+his aid.
+
+Once more he caught sight of the tail light, this time quite a distance
+ahead. Letting out the final ounce of energy he succeeded in quickening
+his speed a little. He ran and ran, but his breathing became alarmingly
+heavy. It would not be long before his wind gave out, but at least he
+would have the satisfaction of knowing that he had done his best. His
+gait was growing wabbly when the unexpected occurrence for which he had
+been hoping came along.
+
+Not even a village street is quite so dead as is the financial section
+of New York in the small hours. Skyscrapers, towering in a jungle of
+silence and dim lights, give a majestic touch to a stillness that is
+seldom broken, save by the footfalls of policemen and private watchmen.
+To Cole, therefore, it seemed nothing but a stroke of luck that a
+taxicab should come along at that moment. He hailed the driver.
+
+“See that car?” He pointed at the tail light twinkling in the distance.
+“Can you overtake it?”
+
+“I’ll try,” said the chauffeur, peering at him from beneath the visor
+of his cap. “This is a pretty good old boat, though she ain’t much on
+looks. Good for a fine if I get pinched?”
+
+“Sure,” said Cole easily, though not altogether unmindful of the
+slender roll in his pocket. He stepped in, and the cab jumped forward.
+It rattled and lurched and creaked in the joints, as if in imminent
+danger of falling to pieces, but he noticed with satisfaction that it
+had a surprising capacity for speed. It swerved and slithered at a
+giddy rate, at times almost jogging him out of his seat.
+
+Pursued and pursuer wound their way out of the maze of chopped-up and
+tangled streets to the south of Washington Square. The car ahead swung
+into Fifth Avenue, at a slightly reduced speed, and the taxicab slowed
+down accordingly. From now on it was not only easier to keep up with
+the larger car, but there was also less danger of the fugitive becoming
+aware of pursuit, for, even at that hour, there was a sprinkling of
+traffic on the avenue.
+
+It suddenly dawned on Cole that he was in a unique position. The
+capture of the hunchback now seemed certain, but what was he to do with
+the man after he had caught him? If he turned him over to the police,
+which seemed the proper and regular thing to do, he would be compelled
+to tell things which, in a sense, he was pledged not to reveal. Despite
+all that had happened and notwithstanding the harsh treatment inflicted
+on him, he had come away with a rather high opinion of The Unknown
+Seven. They had trusted him, at least for a time, until the coming of
+the hunchback turned their suspicions against him, and Cole was not
+inclined to violate a trust.
+
+Now, that he came to think of it, there was really very little he could
+tell, even if he were disposed to divulge what he knew. In a strict
+sense he did not know that the hunchback had murdered Reeves. For
+that matter he did not know that Reeves was dead. Though personally
+convinced on both points he could not tell a convincing story to the
+police, for he had neither witnessed the commission of the crime nor
+seen Reeves’ dead body.
+
+Still another thought came to him as he bobbed up and down and from
+side to side in the cab. He gave a short, dazed laugh. Even if he had
+witnessed the deed and seen the body he would have been unable to
+direct the police to the scene of the crime. His dizzying descent in
+the elevator shaft had left him a trifle giddy. He had rushed away in
+great haste, his whole mind fixed on the one idea that the hunchback
+must not be permitted to get away. In his hurry he had given no thought
+to the location of the building. He had strained every nerve and muscle
+in his efforts to keep the car in sight, and there had been no time to
+notice street signs. Like many a New Yorker, he had seldom had occasion
+to visit the financial section, and many of the streets in that
+district were nothing but names to him.
+
+Though there was ample extenuation, Cole chided himself for a
+blunderer. He had missed his chance to learn where the headquarters
+of The Unknown Seven was situated. The general boundaries of the
+neighborhood were a shade more clearly defined in his mind, but he
+knew scarcely more than he had known before. The rendezvous of the
+organization could be in any one of half a hundred buildings. Even
+if he should stumble upon the right one he doubted whether he would
+recognize it.
+
+In the midst of his musings the cab stopped with a suddenness that
+jerked him out of his seat. He glanced out and saw that the hunchback’s
+car had halted two blocks ahead. They were somewhere in the Sixties,
+and to the west were the black masses of the park. The hunchback was
+getting out and turning down the side street, but car and driver were
+proceeding north.
+
+A suspicion was dawning in Cole’s mind as he stepped out of the
+taxicab. It was rather odd that the chase should have ended at this
+particular point. He paid the chauffeur, adding a generous tip to the
+fare. He hurried to the corner where the car had stopped and swung into
+the side street, just in time to see the hunchback disappear in the
+shadow of a house. Cole hastened after him, stopping before a dark and
+somber house with a brownstone front.
+
+His hazy suspicion was confirmed. It was odd how the scattered pieces
+of the mystery were beginning to dovetail. His pursuit of the hunchback
+had led him to the house of Doctor Dickson Latham.
+
+
+
+
+ CHAPTER XI
+
+ BEHIND THE LOCKED DOOR
+
+
+The moon was shining through a silver-gray mist, giving the row of
+buildings a shadowy appearance. A fresh fragrance drifted out from the
+park, on the scarcely perceptible breeze. A milk cart rattled down the
+block; otherwise the street was deserted.
+
+Cole peered sharply into the dark basement entrance. He suspected the
+hunchback had entered the doctor’s house that way. Down the steps he
+went and tried the knob, but the door was locked. The two windows on
+each side were protected by iron bars. He hesitated for a moment, and
+then he mounted the steps to the main entrance and rang the bell. There
+seemed to be nothing else he could do, and the shifty-tongued doctor
+interested him strangely. Latham’s evasions would be entertaining, if
+nothing else.
+
+He waited patiently, for he had many things to consider. Just what
+trend the forthcoming interview was to take he did not know. That
+the hunchback should have taken refuge in the physician’s house was
+significant, especially since there were good reasons for supposing
+that Latham was responsible for the wrecking of Reeves’ mind. That he
+had also instigated the murder of the maniac seemed only a reasonable
+sequence of the first supposition. In this connection Professor
+Carmody’s visit to the doctor’s house yesterday was a highly
+interesting circumstance. Perhaps the two rogues had planned the murder
+then.
+
+Cole rang again. At the same time he brushed all hasty inferences and
+surmises from his mind. He came back to the point that, as far as hard
+facts were concerned, he knew next to nothing. He did not even have a
+good reason for placing the hunchback under arrest. If he turned the
+fellow over to the police he would probably be only laughed at for his
+trouble. The hunchback would brazen out of it, and Cole would not have
+a leg to stand on. As for Doctor Latham——
+
+He rang again more emphatically this time. Then he listened to the
+queer noises which the reverberations stirred up within the dark house.
+As for Doctor Latham, Cole could hope to do no more than draw the
+doctor out by deftly aimed questions. It was scarcely to be expected
+that such a slippery individual as Dickson Latham would betray himself,
+yet something might come of the interview. The doctor might get
+careless, or Cole might succeed in confusing him.
+
+Once more he reached for the button, but just then a step sounded in
+the hall. The door came open. It was the doctor himself who admitted
+his early caller. It was dark where they stood, and Cole could see
+little else than a black beard and a long dressing gown, but he fancied
+there were signs of repressed irritation about the doctor, as he
+recognized his visitor.
+
+“Ah, it’s you, Mr. Stone. Please step in.”
+
+The voice was affable enough. Cole followed him through the hall, the
+reception room, and into the physician’s office. When they faced each
+other across the desk, Latham seemed to have recovered his usual ease
+of manners. “Nerves again, Mr. Stone?” he asked pleasantly.
+
+“No; only a slight headache,” said Cole.
+
+“And you wish me to prescribe something?”
+
+“Yes, but it isn’t drugs I want. I came here hoping you would
+cure my headache by removing the cause. I have an acute case of
+flabbergastation.”
+
+Doctor Latham’s bearded lips parted in a thin flash of very white
+teeth. Cole thought there was something Machiavellian about the smile.
+The physician reached out an arm and passed a box of cigars across the
+desk. A startled gleam flashed into Cole’s eyes. The movement of the
+doctor’s arm had wrinkled the sleeve of the dressing gown and exposed
+a narrow rim of the cuff of his pajama jacket. The cuff was pale blue,
+and just above the rim was a stain.
+
+“I can recommend these perfectos,” said Latham genially.
+
+Cole, easily hiding his surprise, accepted one. The doctor struck a
+match, and the stain became visible once more, as he helped Cole to a
+light. It was a fresh blot of a dark tinge, probably not more than an
+hour old.
+
+“What is it that flabbergasts you, Mr. Stone?” inquired the physician,
+after each man had pulled appreciatively at his cigar. The question was
+accompanied with a slight and seemingly casual glance at a door in the
+rear of the office.
+
+The glance had not escaped Cole. He picked his words carefully.
+“Fifteen or twenty minutes ago,” he began, “a man entered your house.”
+
+“Yes?” asked the physician in a toneless voice.
+
+“A hunchback,” Cole went on, guessing that the doctor had carefully
+hidden the fellow, while Cole had been kept waiting outside the door.
+“He entered your basement, unless I’m mistaken. Odd time for a call,
+doctor.”
+
+“A physician, as you undoubtedly know, receives callers at all hours.
+Nothing unusual in that.”
+
+“But you will admit that this fellow’s mode of entrance was rather
+irregular? A physician’s patients do not usually sneak in the basement
+way.”
+
+“Very true, but please come to the point, Mr. Stone. You must grant
+that I have a right to receive visitors any way I choose, even through
+the chimney, if it pleases my fancy. You tell me that a hunchback
+entered my house by the basement door. I neither deny nor affirm it,
+but, without wishing to seem rude, may I ask what it is to you?”
+
+“Suppose the fellow were a criminal?”
+
+“I never inquire into the moral character of my patients. Their
+physical welfare is all that concerns me.”
+
+“But suppose this individual had committed a murder? You would not care
+to harbor a murderer in your house, would you?”
+
+A slight flicker of uneasiness showed in the doctor’s eyes. “A
+murderer? Aren’t you carrying your suppositions rather too far, Mr.
+Stone?”
+
+Again he cast a sidelong glance at the inner door. Cole sensed a hidden
+significance in the doctor’s attention to that door. It puzzled him
+almost as much as did the stain on the cuff. He thought quickly,
+estimating how much he stood to gain or lose by a direct attack.
+
+“I’m not supposing,” he declared bluntly. “I know there is a murderer
+in your house.”
+
+“Oh!” The doctor’s tone was tense and very low. “Whom did he murder?”
+
+“Malcolm Reeves.”
+
+“Mal—Malcolm Reeves?” In an instant the physician had kicked back his
+chair and was on his feet. With the cigar tightly clamped between his
+bearded lips he stared hard at Cole. His eyes were bright as metal, but
+there was a glint of grave concern in their depths. In that moment Cole
+would have been ready to swear that Latham’s consternation was genuine.
+
+“Is Reeves dead?” asked the doctor hoarsely.
+
+Cole gave him a level glance. “He was murdered less than two hours ago,
+and the murderer is in your house.”
+
+The physician stared for a moment longer. An indistinct mutter came
+from his lips. Cole wondered whether his face was not pale under the
+glossy black beard. Despite his bewilderment and his feeling that the
+doctor’s emotions were sincere, he glowed inwardly with satisfaction.
+At last Latham’s superb composure had been shattered; now he must
+pursue his advantage before the doctor could rally his mental forces
+and ply him with unanswerable questions.
+
+“Doctor Latham,” he asked quickly, “do you deny that there is a
+hunchbacked fellow in the house?”
+
+The doctor sat down again. “I don’t feel called upon either to deny or
+affirm it,” he declared.
+
+Cole leaned forward across the desk. “How did that stain get on your
+cuff, doctor?”
+
+The physician’s arm was stretched out flat on the table, and Cole
+pointed to the soiled cuff. Latham looked down; for an instant, as he
+saw the blot, his eyes widened in astonishment.
+
+“Oh, that!” He shrugged his shoulders. “I had a simple surgical case
+a while ago. It wasn’t serious enough to take to a hospital, so I
+performed it in my own office.”
+
+“I didn’t know physicians ever performed operations in their pajamas.
+No accounting for eccentricities, though. Will you do me a favor,
+doctor?”
+
+“That depends. What is it?”
+
+Cole pointed carelessly to the door at which the doctor had been
+covertly glancing from time to time.
+
+“I would like to see what is behind that door, if you don’t mind,” he
+remarked languidly.
+
+Again a gleam of uneasiness crept into the doctor’s eyes. He regarded
+Cole intently, as if trying to ferret out the reason for the request.
+Cole, a thin smile on his lips, was puffing leisurely at his cigar.
+
+“Why?” demanded the doctor.
+
+“Just a fancy. You have no objection, I hope?”
+
+The doctor drew himself up. He sat stiffly erect in his chair. A mask
+seemed to fall from his face. Dropping all pretense of geniality, his
+features took on a threatening look. “I don’t care to humor your fancy,
+Mr. Stone,” he declared coldly.
+
+With excessive care Cole ashed his cigar. Then he got up and, with a
+slow, but firm, tread, walked toward the door in the rear. His fingers
+closed around the knob.
+
+“Stop!” cried the doctor sharply.
+
+Cole turned and gave him an amused glance.
+
+“You are a detective, I suppose?” said Latham.
+
+“In a way,” admitted Cole modestly.
+
+“Have you a search warrant?”
+
+Cole shook his head.
+
+“Then I must regard you as a trespasser. Mr. Stone, the moment you open
+that door you will be a dead man.”
+
+He reached into a pocket of his dressing gown. In the next instant a
+small pistol glittered banefully in his hand. He raised it till Cole
+could gaze straight into the muzzle. His eyes, as he looked ominously
+at him, emitted the same cold, metallic gleam as the barrel of the
+weapon.
+
+Cole gave him a long, searching look, and he was a keen judge of faces.
+At the end of the inspection he shrugged. “Doctor Latham,” he said
+evenly, “you haven’t the nerve to kill me.” He turned the knob and
+walked in.
+
+
+
+
+ CHAPTER XII
+
+ IN FOUR ROUNDS
+
+
+In stony silence Doctor Latham watched the bold move. As Cole opened
+the door, a diffident look came into his face. He toyed awkwardly with
+the pistol, looked dubiously at the barrel, finally put the weapon back
+in his pocket. “It seems you win this round,” he muttered.
+
+The room which Cole had entered was dark. His hand fumbled along the
+wall till he found a knob. At his pressure a light appeared, and it
+revealed a man sprawled out in a chair. Except that the coat had been
+removed he was fully dressed, and it seemed to Cole that he was sound
+asleep.
+
+He recognized the sallow face of the hunchback, having caught a brief
+glimpse of it just as the elevator started. It was not a pleasant face.
+The twisted lips looked as though the teeth had been bared in a snarl
+just before the man fell asleep. Cole thought he might be a thug or
+professional gunman. He looked away and saw Latham in the doorway.
+
+“You’re a cool one,” murmured the physician, a trace of admiration in
+his tone. “Didn’t you know I was ready to shoot you?”
+
+“You didn’t,” was the laconic answer.
+
+Latham came closer. He was once more suave and genial. Cole fancied
+his astute brain was at work on a scheme of some sort. “Have you seen
+enough to repay you for the risk you took?” he inquired. “Is this the
+man you are looking for?”
+
+Cole nodded. “He’s the one who murdered Reeves. Tough-looking customer!
+What have you done to him, doctor?”
+
+The Machiavellian smile came back. “He was in a bad way. I had to give
+him a hypodermic. That’s why his crime, if he committed one, doesn’t
+seem to weigh very heavily on his conscience. What are your intentions
+in regard to my patient, Mr. Stone?”
+
+Cole stepped closer to the recumbent man. The fellow looked indeed as
+though he were deep in drug-induced sleep. Cole raised the arm nearest
+him and turned back the shirt sleeve. A little below the elbow there
+was a small puncture. He dropped the limp arm and turned away. His
+head was full of perplexities and contradictions. A little while ago
+certain phases of the mystery had seemed to dovetail to perfection, but
+now things were taking an incongruous turn. He felt the physician was
+inwardly laughing at his bewilderment.
+
+“Well, Mr. Stone?” he inquired softly.
+
+Cole was in a quandary, but he tried hard not to show it. For the
+present the wily doctor had several strategical advantages, and
+evidently he knew how to use them. It would not be easy to take the
+unconscious man away. Even if it could be done, Cole would not know
+where to take him. On the other hand, it would not do to let him get
+away, as he undoubtedly would as soon as he recovered from the effects
+of the drug.
+
+“This man is my patient,” continued the doctor, “and I strongly advise
+against disturbing him for the present. I believe a physician’s advice
+is usually heeded in such cases.”
+
+“Your patient seemed to be in excellent health a little while ago,”
+observed Cole.
+
+“Really, you must permit me to be the judge as to his physical
+condition.”
+
+Cole eyed him levelly. “You are a very clever man, Doctor Latham. I
+believe you deliberately drugged this so-called patient of yours so
+that he couldn’t be removed. It was a fairly ingenious stroke.”
+
+Latham gave him a curious glance. “That’s a very odd way of looking at
+the situation,” he remarked thoughtfully. “I wonder if you aren’t a bit
+disingenuous. However, it doesn’t matter. This seems to be my round.”
+
+His faintly gloating tone nettled Cole. As far as he could see he was
+outmaneuvered on every point. Hopeless as the situation seemed to be,
+he was determined not to leave the house a defeated man. He rekindled
+his cigar, then gazed with mild reproach at the glowing tip. A cigar
+never gave him the mental stimulus that he derived from his musty
+old pipe at home. Besides, the doctor’s slyly amused glances were
+disconcerting. Cole’s thoughts would not travel in a straight line,
+and he grew more uncomfortable as he noticed that his helplessness was
+beginning to impress the doctor as queer.
+
+He turned, placed the half-smoked cigar on a tray, and glanced through
+the open door leading into the office. The nickel trimmings of a
+telephone gleamed under the electric drop light over the desk. The
+sight of the instrument seemed to give Cole an idea. Deliberately he
+walked into the other room and picked up the directory.
+
+“May I ask what you intend doing?” inquired the physician, following
+him.
+
+“I know a doctor who lives not far from here,” said Cole absently,
+while he hastily turned the pages of the book. “I’m going to call him
+in for a consultation over your patient. If the fellow is in a bad way,
+two doctors are better than one. If there’s nothing wrong with him, I
+want to know it. Ah!” his index finger halted in the center of a page.
+“Plaza 28826.”
+
+A faint mutter of dismay escaped the doctor. He stood at Cole’s back,
+while the detective put the receiver to his ear.
+
+“A consultation is quite unnecessary, I assure you,” declared Latham.
+
+Cole grinned into the transmitter. He suspected Latham would agree to
+bring his “patient” back to consciousness rather than have another
+physician called in. A thousand slight murmurs sounded on the wire, and
+then came the operator’s brisk “Number, please.”
+
+Cole spoke the number distinctly. He expected Latham would yield rather
+than suffer a blow to his professional reputation, but the physician’s
+cunning rendered the matter uncertain. And, even if his ruse succeeded,
+Cole would score only a temporary advantage. He was not yet sure what
+his next move was to be. While waiting for the connection he glanced
+over his shoulder. Latham, hands clasped at his back, was walking back
+and forth.
+
+Suddenly Cole’s face went blank. A jarring noise sounded in his ears.
+In the next instant he knew he was holding a dead instrument in his
+hand. All sounds had abruptly ceased. He heard Latham’s triumphant
+chuckle as he hung up the receiver.
+
+“It appears the third round is also mine,” murmured Latham, his bearded
+lips parting in a gratified smile. In his right hand he held a pair of
+steel nippers.
+
+Cole gritted his teeth, but smiled complacently. “I would call it a
+draw,” he said. “Your act of cutting the wire was a confession, doctor;
+a confession that you are up to deviltry. I knew it all along, of
+course, but I’m glad you showed your hand so plainly. It’s an advantage
+to me to know that you have something to fear.”
+
+“I hope you derive a lot of satisfaction from it,” declared Latham
+easily. “I fail to see how it is going to do you any practical good,
+though.”
+
+Cole himself was not quite clear on that point. It was a moral
+advantage rather than a physical one. He gazed steadily at the
+physician, studying the triangular outlines of the black, neatly
+trimmed beard. It was a bit tantalizing to consider how many shifting
+expressions that glossy appendage might conceal. It acted as a mask,
+and he was permitted to see through it only when the bearded lips
+parted in a flash of teeth. Just now the face told him nothing. It
+merely gave him an impression of a man of unfathomable secrets and a
+deeply plotting mind. Cole felt at once baffled and fascinated.
+
+“I am curious to know what you will try next,” said Latham after a long
+pause. “I don’t want to seem inhospitable, but I’m getting deucedly
+sleepy.” He yawned ostentatiously. “If you have nothing further to
+propose——” He looked significantly at the door.
+
+Cole considered for a moment longer, then he selected the most
+comfortable chair in the room and sat down. With a languid air he
+stretched out his legs and leaned back. “I am worried about your
+patient,” he declared, with a sly wink at the room in the rear. “If you
+have no objection, I’ll hang around till he comes to. This is a very
+comfortable chair. Could I trouble you for another of those excellent
+cigars?”
+
+The doctor stood in front of him, and Cole fancied there was a frown
+beneath the beard. “You are going too far,” said Latham severely.
+“Suppose I should throw you out?”
+
+“That would be very rude, doctor. Besides, it couldn’t be done.”
+
+Latham came a step closer. Slowly his crafty eyes moved up and down
+Cole’s figure. Evidently he concluded that the languid appearance of
+the man in the chair was deceptive.
+
+“I might summon help,” he suggested.
+
+“You might, but I hardly think you will. Being a prudent man, you
+realize it wouldn’t do to stir up things. It’s far preferable, from
+your point of view, to confine this interview to ourselves. What about
+another of those cigars, doctor?”
+
+Latham did not move. His eyelids narrowed a trifle as he continued to
+gaze at Cole. “You puzzle me,” he declared. “You come here representing
+yourself to be a detective, but your conduct is very peculiar. You say
+the hunchback in the other room is a murderer, but you have made no
+move toward arresting him.”
+
+“I am naturally lazy,” confessed Cole blandly, “and it would be too
+much of an exertion to carry the fellow out of here on my back.”
+
+“Have you a warrant for his arrest?”
+
+“None is needed,” said Cole easily, though he perceived that the
+conversation was taking a dangerous turn. “It is enough that I have
+reasonable cause for believing that the man has committed a felony.”
+
+His tone faltered slightly on the word “reasonable.” In his imagination
+he could picture the faces of the police officials, if he should
+undertake to tell them what had happened.
+
+Latham continued his piercing scrutiny for a few moments longer. “You
+looked to me like an impostor,” he declared. “I’ll wager you haven’t
+even so much as a pair of handcuffs on your person.”
+
+Cole jerked himself up straight in the chair. His twinkling eyes
+bespoke an inspiration. From his pocket he drew a small pair of steel
+links. “Small, but substantial,” he said musingly. “A friend gave them
+to me once. I have so little use for them that I wouldn’t carry them
+around except for the fact that they are so light and take so little
+space in the pocket. Once, in an unexpected pinch, they proved handy,
+and I have been carrying them ever since.”
+
+He got up and briskly walked into the room in the rear. A muffled
+exclamation escaped the doctor, as Cole fastened one of the links
+around the hunchback’s wrist. Then, with surprising ease, he lifted the
+man out of the chair and carried him to an operating table in a corner
+of the room.
+
+“What are you doing?” inquired Latham sharply, too amazed at Cole’s
+conduct to be able to interfere.
+
+A short laugh was Cole’s only answer. He stretched the unconscious man
+out on the operating table.
+
+“Are you crazy?” spluttered the doctor. “What——” He stopped short as he
+saw Cole’s intention, but now it was too late to act. Cole had placed
+the limp figure in such a way that the arm, from which the steel links
+dangled, was hanging down along the side of the table. In a twinkling
+he had fastened the other link around one of the iron legs. The
+unconscious man was now securely chained to the table.
+
+Cole turned and regarded the physician with a good-humored expression.
+“My round, and it’s as good as a knock-out,” he observed.
+
+Latham stared dumfoundedly. He saw what had happened, but he appeared
+at a loss to grasp the meaning of it. “What do you hope to gain by such
+tomfoolery?” he demanded.
+
+“A lot,” said Cole softly. “Your patient can’t get away unless he
+takes the table with him, and that would attract attention. A fleeing
+murderer is under quite a handicap when he is chained to an operating
+table. I notice it is all iron and strongly built. The legs are
+soldered to the top, so it won’t be easy to take it apart. A skilled
+craftsman could do it, but I believe you have a strong aversion against
+calling in outsiders.”
+
+The cold gleam in Latham’s eyes told that he understood. His gaze was
+fixed in a speculative way on the two steel links.
+
+“They could be filed off,” admitted Cole, guessing his thoughts, “but
+it would take a long time to get through the chilled steel of which
+they are made. An expert might be able to unlock them, but there again
+you are hampered by your prejudice against outsiders. You can’t slip
+the link off the iron leg, for the braces down below prevent that.
+Barring accidents, I think my man will stay here till I’m ready to come
+and get him.”
+
+Doctor Latham seemed a trifle dazed. He ran his fingers awkwardly
+through his beard while looking bewilderedly at Cole. “You are an
+astounding person,” he declared.
+
+“You are another, doctor.” Cole smiled engagingly. “Sorry to have
+interrupted your night’s rest. Are you going to charge me for this
+visit? I believe it was ten dollars last time.”
+
+“Go to blazes!” said Doctor Latham. He stood motionless beside the
+unconscious man, while Cole walked out of the room.
+
+
+
+
+ CHAPTER XIII
+
+ THE MORNING’S MAIL
+
+
+Just as the clock struck eleven, the following morning, Kingdon Cole
+emerged in a tingle and glow from his cold shower. He had retired
+shortly before dawn, so he had considered himself entitled to sleep
+till a late hour, and now he felt the exuberant strength and freshness
+that make a man eager for work.
+
+He stepped to the window, raised the shade, and looked out upon a gray
+and drizzly world. He scowled a little. Like all highly sensitized
+persons, he was easily susceptible to the weather. When the sky was
+clouded, his face was apt to wear a frown. When the sun shone, his face
+shone with it. A glance in the evening at the weather forecast could
+have told him what mood he was to be in the next day, granting that
+weather predictions were always accurate.
+
+He turned from the window as Toots, with a plaintive “meow,” rubbed her
+curled back against his leg. “Hungry?” inquired Cole, looking at the
+cat with an expression of grave responsibility.
+
+Toots held her tail erect and seemed to think the question wholly
+superfluous. With a dutiful air Cole brought in the milk bottle, also
+two letters which he found outside his door. After a glance at the
+handwriting he tossed them on the table and proceeded to appease Toots’
+hunger. He went about it with all the awkwardness of an overgrown boy,
+spilling a part of the milk beside the saucer, then stood aside and
+watched Toots lick it up.
+
+Over his coffee and toast, a few minutes later, he started to read
+his mail. One of the letters was addressed in a strange feminine
+handwriting, and he opened it first. He suddenly stopped eating and
+took in the contents at a glance. The note read:
+
+“Come back. I trust you. +Miss B.+”
+
+Beneath the signature was a row of X’s. Cole counted seven of them;
+they were the insignia of The Unknown Seven, of course. It was
+gratifying to know that the mysterious Miss Brown still had faith in
+him, despite the suspicions of the other members of the organization,
+but her frankness puzzled him. If the others thought him guilty of
+duplicity, why did she not think likewise? She had seen and heard
+precisely the same things that the others had seen and heard. As far as
+he knew, she had no facts on which her favorable opinion of him could
+have been based. What, then, was the reason for her attitude?
+
+“Woman’s intuition, I suppose,” mused Cole with a glance at Toots.
+“That probably accounts for it. But how does the charming Miss Brown
+expect me to find my way back to the headquarters of The Unknown Seven?
+To locate the building would be about as ticklish a job as finding
+a needle in a haystack. I don’t see why she—— Yes, I do! She has
+naturally taken it for granted that I had sense enough to make a mental
+note of the street and number when I made my hasty exit last night. She
+doesn’t know what a half-cocked idiot I am. Shucks!”
+
+Cole made a wry face. Somehow he must manage to find the headquarters
+of The Unknown Seven. Unless he answered Miss Brown’s summons, she
+would naturally suppose that her faith in him had been misplaced and
+that he was remaining away because of a sense of guilt. Cole resolved
+he would canvass every block in lower Manhattan before permitting such
+a thing to happen. How to go about it was another matter, however. A
+systematic search would eventually lead him to the building, but that
+would mean a waste of valuable time. He must find the headquarters
+of The Unknown Seven without delay, not only because Miss Brown had
+faith in him, but also for the more practical reason that he would not
+know what to do with the hunchback until he had positive knowledge of
+Malcolm Reeves’ death.
+
+He had no fear that his prisoner would escape from Doctor Latham’s
+house. He had left the hunchback in a predicament from which the
+astute physician would not be able to release him without a great deal
+of difficulty; but Cole did not depend on that alone. Tony Pinto, a
+ragged urchin whose habitat was the picturesquely squalid section
+around Chatham Square, was watching the doctor’s residence. Cole, who
+had earned the lad’s everlasting gratitude by once doing him a small
+service, had instructed him to keep a sharp eye on the place. Tony
+had the wits of a fox and the legs of a deer, and a great ambition
+to become a detective. If an attempt should be made to spirit the
+hunchback away, Tony would find it out and report to Cole instantly.
+
+Finishing his breakfast he lighted his pipe and composed himself
+for hard thinking. The tobacco smoke grew so thick in the room that
+Toots blinked at him reproachfully. Suddenly an idea came to him. He
+recalled having heard Grover Carlin say that a number of the members
+of The Unknown Seven had offices in the building. Cole had recognized
+several of the members, the previous evening, from photographs that had
+appeared from time to time in the newspapers, in connection with their
+social and financial activities. Right here was a clew to the location
+of the headquarters.
+
+He picked up the telephone directory and found the name of Vincent
+de Witte, one of the men whom he had recognized. He glanced at the
+financier’s office address, and he saw his clew slipping out of his
+fingers. The address was somewhere in Union Square, much too far north
+to be anywhere near the building he was searching for. Next he looked
+up the address of Stephen Aldrich, but with no more success. The
+philanthropist’s offices, according to the directory, were in the Times
+Square district.
+
+Cole tried two other names, then tossed the book away in disgust.
+It came to him that men like De Witte and Aldrich were engaged in
+multifarious enterprises and probably had two or more suites of
+offices in different sections of the city. Likely as not the business
+enterprises which they were conducting in the headquarters building
+were under corporate names, not generally known to the public. It was
+not to be expected that men so shrewd as The Unknown Seven had proven
+themselves to be would leave even the remotest clew to the location of
+their rendezvous. Cole saw he must try something else.
+
+He gazed hard into the monkey’s face graven into the bowl of his pipe.
+What with the drizzle outside and the chaotic condition of his mind,
+he scowled into the tobacco haze that surrounded him. Why the deuce
+hadn’t Miss Brown telephoned him instead of mailing him a letter?
+Why was it that women of her type were so prone either to underrate
+or overrate the intelligence of the sterner sex? They never accepted
+men at their true valuation, but their opinions were always colored
+by bias of one kind or another. Cole squinted at Toots while these
+thoughts ran through his mind. He had a distinct impression that that
+dainty specimen of femininity always regarded him with a sort of lofty
+tolerance. Miss Brown, on the other hand——
+
+Suddenly he remembered the other letter. At first glance he had
+recognized the cramped hand of Hector Englebreth’s secretary. He
+snipped off the margin of the envelope. Without doubt the letter
+contained a sharp reminder that Cole had promised to give his client a
+supplementary report on the condition of Malcolm Reeves. He anticipated
+a crisply phrased note as he drew out the inclosure. Then a surprise
+came to him. The envelope contained not only a letter, but a check
+besides. It was for a generous amount. Evidently his client had sent
+him something on account. Thoughtful of Englebreth! Cole put the check
+aside and glanced at the note, and then he received a second surprise.
+He read:
+
+“+Dear Sir+: Mr. Englebreth desires me to notify you that he no longer
+requires your services. Inclosed please find check for services
+rendered to date.”
+
+Cole stared hard at the few typewritten lines. The stiffly worded
+communication was signed by Hector Englebreth’s secretary. The prim
+type and the severe plainness of the engraved name and address in the
+upper left-hand corner seemed to convey a breath of the heavy, tomblike
+atmosphere that pervaded the Englebreth house.
+
+He chuckled lightly as he flung the letter aside. It was not the first
+time that his independent conduct had lost him a client, and the fact
+that he was now cut off from all official contact with the Reeves
+mystery did not worry him in the least. There was nothing to prevent
+him from attacking the problem on his own account. The curt dismissal
+puzzled him, however. He wondered what he had done to displease
+Englebreth. His client’s warning, spoken just as Cole was leaving the
+somber old house the other day, flashed across his mind.
+
+“Be careful,” Englebreth had said.
+
+The words had had a cryptic sound. Cole had wondered at their meaning
+then, and he wondered now. Had Englebreth dismissed him because of
+his failure to heed a warning which he had not understood? Once
+before it had occurred to him that perhaps his client had learned,
+in some mysterious manner, of his relations with The Unknown Seven.
+Was that what had been in Englebreth’s mind when he uttered that
+strange warning? Did his client suspect that Cole was betraying him by
+conducting secret negotiations with an enemy? The idea did not seem
+very plausible, but he could think of no other solution. On the whole
+he felt Englebreth had treated him rather shabbily. He had worked
+hard and loyally on the case. The abrupt dismissal was, in reality, a
+reflection on his honesty. In his resentment he resolved to demand an
+explanation of his former client.
+
+He glanced dubiously at the telephone, recalling that on several
+occasions Englebreth had expressed a dislike to holding conversations
+over the wire, and he decided that an interview, face to face, would be
+more satisfactory. He poured out another saucerful of milk for Toots,
+and half an hour later he was ringing the doorbell of the Englebreth
+house on Fifth Avenue.
+
+The drizzle and the leaden sky conferred an added touch of melancholy
+upon the dismal mansion. The chill, which he always felt on entering
+the house, had a keener edge this time. The rooms, with the window
+shades lowered as always, seemed darker and more oppressively silent
+than usual. The manservant who admitted him regarded him with an air of
+thinly veiled suspicion.
+
+“I’ll see if Mr. Englebreth is at home, sir,” he announced. His feet
+made no sound as he crossed the thickly carpeted floor and passed
+through a door that turned silently on its hinges. In a few moments he
+was back. “Mr. Englebreth is not at home,” he declared, dropping the
+habitual “sir.”
+
+Cole got up from his chair and gave the servant a playful poke in the
+ribs. It was a grotesque piece of levity in that house of frigid
+dignity, but he could not resist the temptation.
+
+“You’re a cheerful liar,” he told the man. Then, while the servant
+gaped after him in a scandalized way, he strode to the door of the
+library and pushed it open. In his wheel chair, beside the black walnut
+table, sat Hector Englebreth. A faint color tinged his white face as he
+saw the detective.
+
+“Good morning, Mr. Englebreth,” said Cole genially, and he drew up
+a chair and sat down. “I know that ‘not at home’ is a polite way of
+saying ‘get out,’ and so I walked right in. Hope you don’t mind.”
+
+Englebreth leaned forward in the chair and scowled forbiddingly. His
+long white fingers beat a restless tattoo on the table. “Why have you
+come?” he demanded. “Did you not receive my letter?”
+
+“I did, and the check, too. Many thanks. The check was quite
+satisfactory, but the letter left too many things unsaid. I am here to
+ask you why I am being fired off the job.”
+
+Englebreth glanced meaningly at the door. Instead of the long dressing
+gown which he usually wore, he was dressed in a suit of plain gray.
+
+“I shall be going out in a few minutes,” he declared stiffly.
+
+“It won’t take you long to answer my question. Don’t you think I am
+entitled to an explanation?”
+
+“Of course, if you insist. I instructed my secretary to write you after
+I had consulted my wife about the matter. Since it is her brother’s
+life that is at stake, she is more vitally concerned than I am, so I
+thought it only proper that she should have her say. After I had placed
+certain facts before her, she agreed with me that your usefulness to us
+is past.”
+
+“Certain facts? What were they?”
+
+“I think you know,” said Englebreth in a hard, dry tone. His deep-set
+eyes, oddly brilliant in contrast to his pale face, regarded Cole
+accusingly. “I am disappointed in you, Mr. Cole. You impressed me as an
+upright, honest man, and I had hoped for better things from you. One of
+the harshest experiences in life is the discovery that one has placed
+his trust in a person who isn’t worthy of it.”
+
+Cole’s face hardened, and there was an ominous gleam in his eye. “I
+think you had better explain that statement, Mr. Englebreth,” he said
+with slow emphasis.
+
+Englebreth shrugged. “You are not candid with me. You know quite well
+what I mean, so why pretend? For instance, can you look me straight in
+the eyes and tell me that you gave a full and truthful report when you
+were here the other day?”
+
+“It was truthful,” said Cole, “and as complete as I could make it under
+the circumstances. If I did not tell quite all I knew, it was because I
+was uncertain in regard to some of the facts.”
+
+A wraith of a smile twisted Englebreth’s thin lips. “And what about the
+warning I gave you? I hoped it would serve as a hint that I was aware
+of certain mysterious movements on your part. Why did you disregard it?”
+
+A long silence ensued. Each man gazed sharply into the other’s eyes.
+There was a glint of steel in Cole’s, a look of stern reproach in
+Englebreth’s.
+
+“Well?” said the invalid. The pale, mirthless smile was still hovering
+about his lips. “What have you to say, Mr. Cole?”
+
+“You have been spying on me evidently?”
+
+“You are using an unpleasant word. I have merely verified certain
+suspicions that concern you. I have also discovered certain facts which
+you have seen fit to conceal from me, facts which have a direct bearing
+on the fate of my brother-in-law. I don’t think there is anything
+further to be said.”
+
+Cole got up. He could not understand where, or by what means, the
+invalid had obtained his information, but it was evident that
+Englebreth’s mind was made up, and that no amount of argument could
+make him change his views.
+
+“You are wrong, Mr. Englebreth,” he said evenly. “A lot of queer things
+have happened, things I don’t understand myself. But, believe it or
+not, I have played fair with you from beginning to end. Some time
+before long I hope to prove it to you.”
+
+“Indeed!” said Englebreth. “I am sure it will be interesting.”
+
+His tone and the smile that accompanied the words made Cole
+instinctively clench his fists. Then he turned away, before his anger
+should get the better of him, and hurried from the house. Out in the
+drizzle and under the gray sky he shook off his resentment and laughed
+at himself. It was ridiculous that a peevish old invalid should make
+him lose his temper. Some day, when he had probed the Reeves affair to
+the bottom, he would make Englebreth eat his words. Just now he had
+more important things to consider than the aspersions of an infirm old
+man.
+
+He crossed the street and was about to board a bus when he chanced
+to look back and saw a large car draw up in front of the house. A
+moment later the massive front door opened, and two servants appeared,
+carrying Englebreth between them. They assisted him into the car, and
+Cole gazed speculatively after the vehicle, as it glided away down
+Fifth Avenue. It was a rare thing for Englebreth to venture beyond
+the gloomy confines of his house, and Cole wondered where he might
+be going. Perhaps he was about to get into touch with his mysterious
+source of information. In that case Cole might learn a great deal by
+following him.
+
+“Taxi, sir,” said a voice, and a cab slowed down at the corner where he
+stood. Cole’s hesitation lasted only a moment longer.
+
+“Follow that green car over there,” he directed. The chauffeur nodded,
+and Cole jumped in. The pursuit proved long and devious; again and
+again Cole chided himself for wasting valuable time. Then the green car
+stopped in front of an office building, and the chauffeur went inside.
+Cole dismissed the taxi and took up a position across the street. From
+where he stood he could catch an occasional glimpse of Englebreth
+through the partly shaded window of the car.
+
+“Guess I’m chasing a wild goose,” he glumly told himself.
+
+Englebreth’s chauffeur reappeared, accompanied by another man, and
+the two lifted the invalid from the car and carried him inside the
+building. Slowly Cole started to cross the street. The man assisting
+the chauffeur seemed to carry his part of the burden awkwardly, and
+Cole could hear the infirm man’s peevish protests. The two men entered
+an elevator with their load, and the cage started upward, just as Cole
+stepped inside the building.
+
+A strange, unaccountable feeling came over him as he gazed after the
+disappearing lift. He was conscious of a faint tingling from head
+to foot. With an abstracted look in his eyes he gazed upward, then
+to the sides. He moved about along the row of elevators, and even
+his footfalls had a curious sound, a sound that he seemed to vaguely
+recognize. The elevator starter approached and inquired what he was
+looking for, but Cole only shook his head in a preoccupied way.
+
+Suddenly he laughed aloud. In a twinkling all his confused impressions
+clarified. Once more he glanced upward. He knew, though he could not
+tell why or how, that far overhead was the rendezvous of The Unknown
+Seven.
+
+
+
+
+ CHAPTER XIV
+
+ COLE’S RUSE
+
+
+Cole’s conviction that he had found the building occupied by The
+Unknown Seven was a matter of instinct rather than reason. He felt that
+once before, and not so long ago, his feet had trod the squares of
+stone that composed the floor. The surroundings had a remotely familiar
+appearance; perhaps he had subconsciously caught a glimpse of them as
+he rushed out in pursuit of the hunchback. Along the wall opposite the
+elevators was a row of small shops, a cigar store, a haberdashery, a
+news stand, and, on the corner, the office of a broker. Cole glanced at
+the signs, and they stirred hazy recollections in the back of his mind.
+
+There could be no doubt of it; chance and Mr. Englebreth had led him to
+the very place he had been most anxious to find.
+
+On the wall in the back was a directory of the tenants. “Security
+Building” it said at the top, and the very name smacked of
+conservatism, stability, and decorum. It spelled efficiency and prose
+and left the imagination untouched. It hinted of things far removed
+from the secret activities of the group of strange men who occupied
+the top floor. He ran his eyes down the names of corporations and
+individuals, but there was none that interested him. Among the former
+were probably several in which members of The Unknown Seven were
+concerned, but he had no means of identifying them.
+
+He turned away and grinned sheepishly, as he noticed that the elevator
+starter was squinting at him in a suspicious way. There were five
+elevators, but, after he had seen them all come up and down, he knew
+that none of them was the automatic one used privately by the members
+of the organization. For a time he was puzzled. At the farther side
+of the shaft was a door marked “Private,” and beyond this a flight of
+stairs. No doubt they were the same stairs he had rushed down the night
+before, after stopping his dizzy descent at the second floor.
+
+But it was the door between the stairs and the shaft that claimed his
+interest. The single word, “Private,” stenciled in black letters on a
+golden-brown surface, piqued his curiosity. It was plainly a hint to
+strangers to keep out. Signs of that kind had held a strong fascination
+for Cole ever since he was a boy. It was just as if some one had dared
+him to pass through the forbidden door. He tried it furtively, though
+well aware of the starter’s oblique scrutiny. It was locked, as he
+had expected, but the word, “Private,” continued to tantalize him.
+What could be on the other side of the locked door? The office of the
+superintendent of the building, perhaps. Or, maybe, the establishment
+of a mail-order concern that did not care for personal relations with
+its customers. On the other hand it might be only a storeroom where the
+scrub women kept their mops and brooms and buckets. All these guesses
+seemed plausible enough, but Cole strongly suspected something entirely
+different. Unless he were greatly mistaken, the door was the entrance
+to the private elevator.
+
+Wishing to verify his surmise, he walked up to the starter and, in a
+tone which might have signified that he was an agent for the building
+department or the inspector of an insurance company, inquired by whom
+the private door was being used.
+
+“A bunch of nuts,” said the starter, moved to loquacity by Cole’s
+official air. “They come an’ go at all hours. They’s some big bugs
+among ’em, too. Guess they belong to wunna them secret societies.”
+
+Cole tried to learn more, but the man became suddenly tight-lipped
+and referred him to the superintendent of the building for further
+information. “It’s agin’ my orders to talk about the tenants,” he added.
+
+Cole nodded understandingly and stepped aside. The locked door seemed
+to bar further progress for the present. Just then he remembered his
+original errand. He had almost forgotten Englebreth. The cage into
+which he had seen the invalid carried had just reached the ground
+floor and was disgorging passengers. Cole waited till it was ready to
+make another trip, then stepped in and slipped a small bill into the
+operator’s hand.
+
+“You carried up a crippled person some ten or fifteen minutes ago,” he
+said in an undertone. “Where did he go?”
+
+“Oh, him!” The operator grinned as he stuffed the bill into a pocket.
+“He comes here every now and then. You’ll find him in 2512, sir. It’s
+the top floor.”
+
+Cole got out on the twenty-fifth floor. To all outward appearances
+it was, indeed, the top floor of the building. The elevator shaft
+terminated in a blank ceiling, and the stairs in the back extended no
+higher. It was somewhat tantalizing to know that directly above him,
+and yet completely out of reach, was the rendezvous of The Unknown
+Seven.
+
+Cole paused outside the door numbered 2512, but he did not knock.
+He could think of no pretext for seeking another interview with
+Englebreth. The office, as was indicated by the sign on the frosted
+glass, was occupied by the Bureau of Civil Research, and he made a
+mental note of the fact. He could see no particular significance in
+Englebreth’s visit to a place of that kind. No doubt the Bureau of
+Civic Research was one of the numerous activities that his former
+client cultivated as a hobby. As far as his original purpose was
+concerned it looked as though Cole had wasted his time, but there was
+consolation in the fact that he had incidentally found the headquarters
+of The Unknown Seven. For the moment, however, he did not see how he
+was to profit by his discovery.
+
+He descended, cast a mildly baffled glance at the private door, and
+went out to lunch. It seemed as if there was nothing for him to do but
+loiter in the vicinity of the building and wait for one of the members
+to appear. Idleness irked him, however, and he disliked the thought
+that such a small thing as a locked door was standing in his way. He
+cudgeled his brain for an idea, as he strolled out of the restaurant.
+
+Suddenly he found one, and he walked two blocks and ducked into a
+subway entrance. Soon he was aboard an uptown train, bound for Doctor
+Latham’s residence. He suspected that in the pockets of the hunchback
+he would find a key that would unlock the door. If his guess had been
+correct, and the door opened into the elevator used by The Unknown
+Seven, then the hunchback must have passed through that very door the
+previous night. He could not have done so unless he had a duplicate
+key. He might have thrown it away, of course, but the chances were that
+it was still in his possession.
+
+Cole looked sharply about him as he walked down the block in which the
+doctor resided. He knew Tony was lurking somewhere in the neighborhood,
+but the youngster had a surprising knack at making himself
+inconspicuous when the occasion demanded it. He rang the doctor’s
+doorbell and was told by the white-capped attendant who admitted him
+that the physician was engaged with a patient. Cole waited in the
+reception room. Evidently Latham did not permit his other enterprises
+to interfere with his practice, for several patients were waiting to
+consult him.
+
+Presently the door opened, and the doctor arched his brows as he saw
+Cole in the waiting group. After a moment’s hesitancy he motioned him
+to enter the consulting room.
+
+“How is the patient, doctor?” inquired Cole briskly, glancing at the
+door in the rear.
+
+Latham stroked his glossy beard. “As well as can be expected,
+considering the awkward position you left him in. He has difficulty
+getting about.”
+
+“Then you have not yet succeeded in extricating him from his
+embarrassing predicament?”
+
+“Oh, no!” said the doctor with a dry laugh. “I haven’t even tried. I
+just removed him to one of the spare bedrooms upstairs. He was in the
+way down here. You wish to have a talk with him, I suppose? I fear it
+is impossible. He grew hysterical a while ago, and I had to give him a
+sedative.”
+
+“It doesn’t matter. I just want to look at him.”
+
+Latham gave him a queer glance, then he smiled knowingly. “I see,” he
+murmured. “You wish to make sure that he hasn’t escaped, despite the
+handicap you imposed on him. This way.”
+
+He opened a door and preceded Cole up a flight of stairs. They entered
+a room, and Cole saw the hunchback stretched out on the operating table
+and sound asleep. The physician watched him narrowly as Cole stepped
+up to the recumbent man and began to explore his pockets. A blank look
+came into the doctor’s eyes when Cole, with a murmur of satisfaction,
+extracted a key.
+
+“As I observed once before,” said Latham, “you are a most astounding
+person. I wonder what the significance of that key might be.”
+
+“Every key has a mission, doctor, and that is to unlock some door.”
+
+The physician regarded him thoughtfully. “I don’t understand you at
+all. You do such unexpected things. I am still wondering what your
+intentions are with respect to my patient.”
+
+“For the present my only concern is that he shan’t get away.”
+
+The doctor pondered for a few moments longer, then he shrugged his
+shoulders, and the two men walked down the stairs in silence. As they
+reached the consultation office and were about to pass into the outer
+room, Latham paused with his hand on the doorknob. “Would it surprise
+you very much,” he asked in slow, incisive accents, “if I were to tell
+you that I am just as anxious as you can possibly be that the fellow
+upstairs shan’t get away?”
+
+Cole’s eyes opened wide. “No, it wouldn’t surprise me. I would simply
+be unable to follow you. You are a deep one, doctor; nothing that you
+could say or do would startle me.”
+
+Latham’s face relaxed in a smile. “I construe that as a compliment.
+Please appease my curiosity on one point. You have taken extraordinary
+precautions against my patient escaping, but what about myself? Aren’t
+you afraid that I might run away?”
+
+“I am not,” said Cole emphatically. “You are not the kind that runs
+away. You work by subtler means than that. Where men of coarser
+mentality would kill an undesirable person, you merely render him
+harmless. If, later on, it should prove absolutely necessary to remove
+him, you hire another man to perform the nasty job. Your sensitive soul
+shrinks from vulgar tactics and sordid actions. For the same reason you
+don’t run away from danger. Instead, you plan your moves so carefully
+in advance that the risk is reduced to the lowest possible minimum, and
+flight becomes unnecessary.”
+
+It was a rather blunt speech, and Cole had spoken so plainly only
+because he wished to watch the effect on the doctor. In the end he
+was disappointed. The expansive beard concealed all outward signs of
+emotion; the face was no more expressive than a wooden image. For just
+a moment the eyes shone with a cold gleam, but that was all. When Cole
+had finished, the bearded lips parted in a pleased smile.
+
+“Thanks,” murmured Latham. “Too bad we appear to be enemies. I like you
+immensely—I really do.”
+
+He held the door open and Cole went out. As he walked toward the subway
+he was almost inclined to share the doctor’s regret that they were
+enemies. There was something at once attractive and repellent about
+Latham. His subtleties, his cool audacity, and his flashing wits made
+him a charming personality, and there was a certain fascination even
+about his cold cynicism and conscienceless manner. Cole came away from
+the doctor’s house with a spell hanging over him. But, aside from these
+things, there were phases of Latham’s character that he could not
+understand. Stray remarks, which the doctor had dropped, and certain
+telltale gestures and mannerisms lingered in his memory while he rode
+downtown.
+
+“A fascinating riddle and a highly accomplished villain,” was his way
+of summing up the doctor’s many-sided personality, as he got out of the
+subway and turned toward the Security Building.
+
+He entered and, key in hand, walked direct to the private door. The
+elevator starter gave him an astonished glance, but did not interfere.
+The key fitted easily. Cole opened the door and stepped in, then
+quickly closed it behind him. He was in a narrow cage, with a small
+electric bulb at the top. He looked about him in bewilderment, for
+there was no sign of any apparatus by which the elevator could be
+started. Carlin had told him that there was a peculiar mechanism that
+could be operated only by the initiated, but all Cole saw was a dial
+with figures along the rim and a knob in the center. It looked like the
+combination lock of a safe.
+
+He twirled the knob back and forth, but without result. He tried
+several different combinations on the dial, but the elevator refused
+to budge. With ingrained stubbornness he persisted in his efforts, but
+in the end he was forced to confess that the task was beyond him. He
+was on the point of getting out when a key grated in the lock. A moment
+later the door came open, and Miss Brown entered the cage.
+
+She started slightly as she saw him. Cole looked at her, and his frown
+melted. She was simply, but charmingly, attired in a tailor-made suit
+of some soft, gray material the name of which was not included in
+Cole’s vocabulary.
+
+“Oh, you came!” she exclaimed.
+
+“Yes, but I didn’t get very far.” Cole regarded her with a half
+humorous, half reproachful glance. Her plain little hat set off
+to perfection the lily-white complexion and the hair like ruffled
+sunshine. “How did you expect me to manipulate the contraption?”
+
+“I didn’t really expect you to,” she told him, while she whirled the
+knob back and forth a number of times. “In fact, I was sure it would
+stump you, but the others had their doubts on that point.”
+
+“I see,” said Cole dryly, as the cage rocketed upward. “If I had
+shown that I knew how to operate the mechanism I would have convicted
+myself of duplicity, and the suspicions of the others would have been
+confirmed. But don’t you see that a man who is clever enough to ferret
+out secrets while blindfolded would not betray himself so flagrantly?”
+
+There was a twinkle of mirth in her deep-blue eyes. “Clever men are
+often vain. You might have construed my note as a challenge to your
+dexterity. It wasn’t that, of course. It was only a test of your
+honesty.”
+
+“And now you are convinced?”
+
+“I was practically convinced before, but the others needed proof.”
+
+“What convinced you?”
+
+The blue eyes regarded him shrewdly, almost impersonally. Cole was
+reminded of a biologist watching a controlled experiment.
+
+“I am seldom mistaken in matters of that kind,” she said simply.
+
+The cage stopped. As they got out, Cole abruptly asked the question
+that had been uppermost in his mind all the time. “What about Reeves?”
+
+“Dead, stabbed through the heart. He was breathing his last when we
+found him.”
+
+Cole nodded grimly. Miss Brown’s words had merely confirmed something
+of which he had been practically certain. They had gone through the
+hidden door in the wall by this time and were now in the corridor. They
+passed several men who bowed respectfully to Miss Brown and cast hard
+glances at Cole. The woman opened a door, and they entered the large
+room with the filing cabinets and the glass globe, the room in which
+Cole had been the night before.
+
+At a desk, with iron-gray head bent over a stack of papers, sat Grover
+Carlin. The lawyer looked up as they entered, and a faint smile flitted
+across his rugged face and tempered the cold gleam in his eyes. “Glad
+to see you, Mr. Cole,” he said in measured tones. “I am also pleasantly
+surprised. Your abrupt departure, just after the murder last night,
+looked pretty bad.”
+
+“I was rather surprised that you didn’t try to stop me.”
+
+Carlin grinned apologetically. “No one thought of doing so until it was
+too late. Everybody, including myself, were stricken senseless by the
+murder. We couldn’t realize that such a thing had happened right here
+in our midst. It seemed unbelievable. All we could think was that you
+were——”
+
+“In cahoots with the murderer,” suggested Cole when the lawyer paused.
+“Well, I admit it looked strange. That murder was about as nervy a
+piece of rascality as I ever heard of. The fellow came here determined
+to carry out his purpose or die in the attempt. Doesn’t his reckless
+audacity and the ease with which he got into your establishment suggest
+something to your mind, Mr. Carlin?”
+
+“Oh, yes a number of things. It suggests that he had powerful
+influences behind him. The motive isn’t far to seek. The men
+responsible for the murder feared that Reeves might recover from the
+effects of the operation and divulge certain facts which would be to
+their detriment. They decided to prevent that by silencing him forever.”
+
+“What else?” asked Cole, eying the lawyer steadily.
+
+Carlin gave him a quizzical glance.
+
+“How do you suppose the fellow got in?” Cole went on. “Where did he
+get the duplicate key to the elevator door? How did he get hold of
+the combination that controls the mechanism? Who told him how to get
+through the wall? How do you explain that, after entering, he walked
+straight to the room where Reeves was? As you probably remember, we
+heard the cry only a few moments after the green light had flashed,
+showing that the murderer knew his way thoroughly.”
+
+Carlin gazed at him hard and long. “Well?” he asked at length.
+
+“Perhaps you still suspect me?” asked Cole lightly.
+
+“No.” The word came a little uncertainly. “I never really suspected
+you. I only had certain doubts about you, doubts which were natural
+under the circumstances. Your return here this afternoon speaks
+volumes. You would scarcely have come back if you had been playing us
+false. I feel I owe you an apology.”
+
+“It’s accepted,” said Cole with a laugh. “But apologies aren’t going to
+remedy matters. Mr. Carlin, there’s a traitor among you.”
+
+Miss Brown, seated near by, caught her breath. The lawyer thrust his
+head forward a little. “Impossible,” he said. “There was a traitor
+among us, as I explained to you, but we got rid of him. For all I know
+he may be dead by this time. I am ready to swear to the reliability of
+every man on our staff.”
+
+Cole seemed inclined to argue the point, but he desisted. His eyes
+twinkled a little, and he looked as though he were content to let
+developments prove the truth of what he had said.
+
+“There is one thing you haven’t explained, Mr. Cole,” said Miss Brown.
+“I am curious to know how you got into the elevator a little while ago.
+Where did you get the key?”
+
+“Oh, the key,” said Cole lightly. “Why, I found it in the murderer’s
+pocket.”
+
+Carlin and Miss Brown looked at him in speechless astonishment.
+
+“I seem to be telling things backward,” Cole went on. “After I left
+here early this morning I gave the fellow a chase and caught him. He’s
+a hunchbacked, dried-up wisp of a man, and as evil looking a specimen
+of humanity as I ever saw.”
+
+Carlin blinked his eyes bewilderedly and looked at Cole, as if he had
+just discovered some new quality in him.
+
+“And you—you caught him?” asked Miss Brown. “Where—how?”
+
+Cole explained, but only very briefly. There was a gleam of sly humor
+in his eye. Toward the end of his recital he did a strange thing. He
+finished it off with an embellishing touch that was not in strict
+accordance with the truth.
+
+“The best part of it all,” he said in casual tones, “is that I have
+the fellow’s confession in black and white. Like most of his kind he
+showed the yellow streak when he saw the game was up. Just how complete
+the confession is I can’t say, but it contains several interesting
+facts.”
+
+“Where is it?” said Carlin excitedly. “Have you got it with you?” He
+half rose from his chair, then sat down again.
+
+“No; it isn’t wise to carry such things on one’s person. No telling
+when you’re going to get knocked down and have your pockets picked. The
+confession is in a safe place. In due time I shall show it to you.”
+
+Carlin seemed inclined to ask questions, but Cole’s face showed plainly
+that he had said all that he intended to say for the present. The
+lawyer got up, walked around the desk and gave the other’s shoulder
+a vigorous slap. “You belong here with us,” he declared with blunt
+emphasis. “You’re just the man for the job. I was sure of it before;
+now I’m doubly certain. You’ve proven your fitness in forty different
+ways. Will you accept?”
+
+Cole’s eyes gleamed wistfully. His smile showed that the proposition
+appealed to him. “You aren’t offering me the position just because I
+wormed a confession out of the hunchback?” he asked guardedly.
+
+“By no means. We were ready to offer you the place a week ago, while
+you were sniffing around the edges of what you called the Carmody case.
+We need you, Cole. Think it over carefully. Consider the opportunities.”
+
+“I have considered them. I am strongly tempted to accept, especially
+since I am out of a job.” Cole gave a whimsical little laugh. “I
+forgot to tell you that Englebreth gave me my walking papers this
+morning. Do you care to take on a man who was fired by his last
+employer?”
+
+“You just bet we do!” Carlin extended his hand, and Cole gripped it
+vigorously. “This evening your appointment will be confirmed by the
+full board, and afterward we’ll introduce you to the members of the
+staff. There’s one matter that’s got to be settled immediately though.
+You’ve got a ticklish problem to solve right at the start, Cole.
+Something must be done about the body of Reeves.”
+
+Cole had already thought of that. He realized what a delicate position
+The Unknown Seven were in. The murder could not be reported to the
+police without jeopardizing the secrecy that, to a great extent, had
+been responsible for the organization’s success. Neither would it be
+easy to turn the body over to the proper authorities without imperiling
+the society’s seclusion. It was a knotty problem, and Cole considered
+it from all angles, while Carlin and Miss Brown showed him over the
+premises.
+
+Cole’s eyes grew wider and wider as he was conducted from room to
+room. On one side of the hall were the offices with their steel filing
+cases, huge nickel-plated safes, desks, typewriters, and even a
+rogues’ gallery, which Cole inspected with avid interest. One room was
+devoted to finger prints and the Bertillon system of identification.
+Adjoining it was a laboratory in which, as Carlin explained, the
+latest scientific discoveries were adapted to the requirements of the
+detective profession.
+
+They crossed the hall, and it seemed to Cole that he was entering
+a different world. This part of the establishment was given over to
+clubrooms, but they were more magnificent than any Cole had ever seen.
+There was a well-appointed gymnasium; a swimming pool in which clear
+water gleamed invitingly in a huge tank of marble; a library containing
+all the latest fiction and belles-lettres; a dining room, an art
+gallery, a pool and billiard parlor, and various cozy little nooks for
+the members.
+
+“You see, Mr. Cole, we believe in combining pleasure and comfort with
+work,” explained Carlin, when the tour of inspection was finished and
+they were back in the office from which they had started. “By the way,
+dinner will be served at six-thirty. You must stay and dine with us.”
+
+Cole agreed after a moment’s hesitation. His glance fell on the
+telephone at Carlin’s desk, and suddenly he seemed to remember
+something.
+
+“Perhaps you would like to use the telephone,” the lawyer suggested.
+“The switchboard is in an office on the tenth floor, and all incoming
+and outgoing calls are relayed through it. No chance of a call being
+traced, you see.”
+
+Cole picked up the telephone and gave the operator the number of his
+landlady. Carlin and Miss Brown started to withdraw, but Cole assured
+them there was nothing personal about the call and asked them to stay.
+
+“That you, Mrs. Armstrong?” he asked when he had got his connection.
+“Mr. Cole speaking. I may not be home till late this evening, and
+I wonder if you’d mind running up and giving Toots her milk. Yes,
+Toots—T-o-o-t-s. The cat, you know. Very good of you. Will you do it
+right away, Mrs. Armstrong? I’ll hold the wire till you come back.
+Toots wasn’t looking well this morning. Acted as if she had a headache
+or something. I’m anxious to know how she is.”
+
+With the receiver at his ear, Cole waited. Carlin stroked his chin
+reflectively. From time to time he gazed in an odd way at the man who
+was to direct the activities of The Unknown Seven, and whose sole
+concern just now appeared to be an ailing cat. Miss Brown was amused
+and took no pains to conceal it.
+
+Cole was kept waiting a long time. At last he pricked up his ears in a
+startled way, as if some surprising news was being told him. He uttered
+a few short exclamations, then hung up the receiver and glanced at his
+watch.
+
+“Mr. Carlin,” he said gravely, in a tone so low that the other two
+could scarcely hear, “two hours ago I sat in this chair and told you
+a lie.” He made a silencing signal with his hand as Miss Brown and
+Carlin started to interrupt. “Yes, a lie. What I said about having
+wrung a confession from the hunchback wasn’t true, though all the
+rest was in strict accordance with the facts. As you may remember, I
+mentioned having put the confession in a safe place. From that you
+might have inferred that I had hidden it at my home, or placed it in a
+safe-deposit box.”
+
+He was speaking in whispers, as if afraid that an eavesdropper might be
+lurking somewhere in the room. The faces of his two listeners showed
+stark bewilderment.
+
+“That was two hours ago,” he went on, “and just now my landlady told me
+that when she went up to my rooms to feed the cat she found everything
+thrown topsy-turvy. The place looked as if a cyclone had struck it.”
+
+Miss Brown gave a little gasp. Carlin’s pupils contracted in
+astonishment. He stared hard at Cole, while a cloud overspread his
+face. One arm was stretched out on the desk, and his fingers clenched
+and unclenched spasmodically.
+
+“They didn’t lose any time,” he muttered. “I don’t understand, but you
+were right, Cole. There’s a traitor among us.”
+
+
+
+
+ CHAPTER XV
+
+ THE TRAITOR UNMASKED
+
+
+With his fingers across his lips, Cole enjoined silence. His glance
+darted quickly over the floor, the ceiling and the walls. He moved
+hither and thither, looking behind desks and filing cases. Finally he
+stepped behind Carlin’s desk and gazed speculatively at a panel of
+grille work in the wall. He held his hand before it and felt a strong
+draft of fresh air. It was obviously a ventilating shaft, and the force
+of the current suggested that air was driven into it by fans.
+
+He whirled round and whispered to Carlin and the girl. “Talk,” he said,
+“talk on any subject but the one you’re thinking on. Be as natural as
+you can.”
+
+Carlin showed plainly that he did not understand, but he nodded
+obediently. Cole tiptoed to a typewriter desk in the rear, and in one
+of the drawers he found a box containing a number of small tools.
+Selecting a screw driver, he went back to the air shaft and loosened
+several of the screws that held the grilled panel. In a few moments he
+could bend it outward, and now he inserted his hand and ran it up and
+down the sides of the shaft.
+
+“Any more of that sauterne left?” he heard Carlin ask the girl.
+
+“About a dozen bottles, I think.”
+
+“We’ll instruct the chef to have it served after the fish course. Just
+to celebrate the occasion, you know. Afterward——”
+
+The lawyer ran on with the dogged air of a soldier obeying orders that
+he doesn’t understand; but Cole heard no more. A sudden tensing of his
+body hinted that he had verified a suspicion. He had found a small
+metal disk attached to the opposite side of the air shaft, and to it
+was affixed a wire that extended upward. A serio-comic smile twisted
+his lips as he rejoined Carlin and Miss Brown. “Guess what I found,” he
+said in a whisper.
+
+The other two stared.
+
+“An amplifying disk and a wire that seems to run out on the roof. A
+dictaphone in other words. There may be others scattered throughout the
+place. My little ruse has shown that these walls have ears.”
+
+The lawyer was too astounded for words. Miss Brown looked fixedly at
+Cole, her lips trembling a little at the corners.
+
+“Did I hear you say something about sauterne?” asked Cole in his usual
+speaking voice, at the same time motioning them to step farther away
+from the shaft in which the disk was hidden. “Favorite drink of mine,
+though I take only an occasional drop of such things.” Again he lowered
+his voice. “To-night I shall get out on the roof and see where the wire
+runs to. Carlin, this is additional proof that there is a renegade
+in our midst. The man who posted the hunchback on how to get in here
+probably installed the dictaphone. It isn’t safe for us to make a
+single move until we have singled him out and rendered him harmless.
+We must attend to that even before we consider what is to be done with
+the body of Reeves.”
+
+Carlin still seemed a trifle dazed. “You are right, of course,” he
+said. “We must get rid of the blackguard at once. It is startling to
+think that any one in our organization may be the traitor. How are we
+going to find him?”
+
+“Leave that to me.” Cole’s narrowing gaze slanted upward, as if his
+thoughts were on the track of an idea. “I have noticed that a man of
+that kind nearly always has a flaw in him of some sort. Generally that
+flaw is cowardice. That gives us an advantage over him, right at the
+start. We’ll play on his cowardice and make him betray himself.”
+
+The lawyer looked somewhat dubious. “How?” he asked.
+
+“I haven’t studied out the details yet,” said Cole, but the slow
+twinkle in his eye told that the idea was assuming shape. “You sowed
+the seed of a plan in my mind when you mentioned sauterne. But don’t
+expect anything spectacular. Sometimes simple measures work best. Can
+you arrange to have the whole organization here for dinner?”
+
+The lawyer fingered his chin in a bewildered way. “It could be managed.
+Most of them have planned to attend, anyway.”
+
+“Splendid! Now, Carlin, since I am to take charge of the work here,
+it would seem only fitting that everybody should drink my health in
+sauterne, wouldn’t it?”
+
+“Cer—certainly,” stammered Carlin.
+
+“You could propose the toast yourself. I know you will do it
+charmingly. And I want you to see to it that everybody is invited to
+drink, including the waiters and the kitchen help. You could explain
+that the toast is to be a sort of pledge of allegiance.”
+
+The lawyer looked blinkingly at Cole, searching his face in vain for a
+sign that he was jesting.
+
+“I’m not sure there is enough sauterne to go around,” observed Miss
+Brown, who evidently shared Carlin’s stupefaction.
+
+“Then use smaller glasses,” suggested Cole. “Besides, in an emergency
+the wine can be thinned out. I think you said there were a dozen
+bottles. That ought to be enough for one round. I can almost taste
+that sauterne already.” He smacked his lips as he consulted his watch.
+“Carlin, I wonder if you would mind telephoning my landlady, Gramercy
+0099, to see if any messages have been received for me. The bright
+youngster who is watching Doctor Latham’s house may have been trying to
+reach me. In the meantime, Miss Brown, I am going to ask you to come
+with me to the dining room. I want to get a general idea of the seating
+arrangement.”
+
+With a long, wondering glance at Cole, the girl conducted him from the
+office, while Carlin cleared his husky throat in preparation for the
+task assigned him.
+
+“You are a very deep person, Mr. Cole,” the girl observed, as she led
+him into the dining room, where tables were set in horseshoe formation.
+“I have a suspicion that you are keeping a perfectly gorgeous scheme
+all to yourself.”
+
+Cole smiled thinly, while his glance roved over snow-white napery and
+brightly polished silver. At times Miss Brown had a naïveté about her
+that he found rather alluring.
+
+“I’ll take you into the secret in a few moments,” he promised. “One
+confidence deserves another, however. How much longer must I go on
+calling you Miss Brown?”
+
+“Don’t you like the name?”
+
+“I do not. I suspect you invented it on the spur of the moment the
+other night. It served well enough for a temporary acquaintanceship,
+but now its usefulness is past.”
+
+“True,” she admitted. “It was an awkward alias, anyhow. How do you like
+Merle Brownell?”
+
+“Much better. One syllable more or less makes a lot of difference at
+times. I take it you are the high priestess of The Unknown Seven?”
+
+“Oh, no! I’m only an odd-job expert. My father, who died three years
+ago, was the founder of the organization. I have hung around, more
+or less, ever since. Most of the time I suspect I am in the way, but
+occasionally I manage to make myself useful.”
+
+Cole regarded her with a look that seemed to say, “You’ll pass.”
+
+“You promised to take me into your secret,” she reminded him. “Aren’t
+you afraid? How do you know that I’m not the traitor, or traitoress?”
+
+“I know,” said Cole firmly, “but don’t ask me how I know. By the way,
+Miss Brownell,” and Cole lowered his voice several octaves, “I see the
+wineglasses haven’t been placed yet. Don’t you think you had better
+speak to the chef about the sauterne?”
+
+She gave him a puzzled look, then a roguish smile illuminated her
+face. “I’m beginning to think the sauterne is the chief ingredient in
+that brilliant idea of yours,” she declared, as she left the room. A
+few moments later Cole followed, turning toward the laboratory which
+Carlin had so proudly shown him. At one wall were several shelves on
+which bottles were placed in long rows. After studying the labels, Cole
+selected one of the bottles and put it in his pocket.
+
+Miss Brownell was supervising the placing of the wineglasses when he
+returned to the dining room. He stood aside and watched silently until
+the task was finished and the waiter had left the room. Then he took
+the bottle from his pocket and stepped to the table.
+
+“Please guard the door,” he told Miss Brownell, speaking in very low
+tones. “If any one wants to enter, keep him out on any pretext you
+like.”
+
+She watched him in astonishment while he went to work. The bottle
+contained a colorless liquid, and with great care he poured a few drops
+into each wineglass.
+
+“Are you going to poison us?” she asked. There was a secretive air
+about Cole that seemed to prohibit talking aloud.
+
+“No, the stuff’s harmless. Nothing but spirits of hartshorn. It will
+mix with the wine, but only a person with a very sensitive tongue will
+notice the queer taste. Such a person, if there should be one among us
+this evening, will notice that the wine has an odd flavor, but that’s
+all. He won’t be able to identify the added ingredient. The quantity is
+too slight.”
+
+“That makes everything very clear of course,” remarked Miss Brownell.
+“About as clear as mud.”
+
+Cole went calmly on with his work. “I suppose it has often occurred
+to you, Miss Brownell, that the imagination is a great aid to one’s
+senses. Tell a person there’s a fire in the next room, and he will
+instantly smell smoke, even though he may not have noticed it before.”
+
+“I don’t see what that has to do with what you are doing.”
+
+“A very great deal. When these glasses have been filled with wine, a
+person, taking a casual sip of the concoction, will not notice the
+queer taste. If he is told, after the second or third sip, that he
+has drunk poisoned wine, the peculiar taste will become noticeable at
+once. Without stopping to try to identify the queer flavor, he will
+instantly become convinced that he has been poisoned, especially if the
+circumstances are such that he already has reason to fear that some
+such thing is going to happen to him. That’s what imagination does to a
+person.”
+
+“Is this some kind of psychological experiment?”
+
+“In a way.” Cole had reached the last glass and was now putting the
+bottle in his pocket. “Incidentally it is interesting to note that a
+person with an uneasy conscience always has a lively imagination. Not
+only can he spot real dangers a mile off, but his guilty conscience
+is constantly surrounding him with imaginary ones. It’s a lucky
+thing, too. If it wasn’t for such frailties in the human make-up,
+we detectives would lose our reputation for achieving brilliant
+deductions.”
+
+Miss Brownell smiled soberly as they walked out. “I think we are
+going to have a most interesting dinner,” she murmured. “I hope your
+psychological experiment will succeed, Mr. Cole. I must run off now and
+powder my nose.”
+
+Cole slipped back to the laboratory and replaced the bottle. A few
+moments later he met Carlin in the corridor. The lawyer told him that
+he had called up Cole’s landlady, but no messages had been received for
+him.
+
+“That means Doctor Latham has made no move yet,” said Cole
+thoughtfully. “He plays a slow and sure hand.”
+
+The lawyer nodded. “Your landlady seemed quite distracted over the
+robbery,” he announced.
+
+“She isn’t the only one. I bet Toots is the most distracted female in
+the world, just now.” Cole gazed gloomily into space, and then a tall,
+broad-shouldered man approached with an easy swagger. Cole’s lips
+twisted into a reminiscent smile, as he recognized the surgeon.
+
+“Hello, Ballinger,” said the lawyer. “Shake hands with Kingdon Cole if
+you dare. I wouldn’t blame him if he were to shoot you on sight, but he
+has a forgiving disposition. Cole has just agreed to become one of us.”
+
+“Splendid!” ejaculated the doctor, and the two men shook hands. As
+their fingers touched, Cole experienced that indescribable something
+that comes from contact with a man of strong personal magnetism.
+Ballinger’s grip could not have been called energetic, but it
+transmitted a subtle electric current.
+
+“You are tackling a man-size job,” remarked the doctor after Carlin
+had withdrawn. “You will have a chance to match your wits against the
+infernal cleverness of the astutest rogue in the country. I suppose
+Carlin has explained the situation to you?”
+
+“He has only given me a few hints. There hasn’t been time for detailed
+explanations. All I know is that a colossal project of some sort is on
+foot, and that The Unknown Seven is trying to put a crimp in it.”
+
+Ballinger took his arm and led him to the smoking room. He extended
+his cigar case, and Cole noticed that his fingers were long, slim,
+and finely tapering, the fingers of one having a deft touch, a strong
+imagination, and a lively dramatic instinct. Again Cole saw that
+Ballinger’s resemblance to Doctor Latham was very slight, extending
+only to outward physique. It was the disguise, and the black beard in
+particular that had produced the likeness.
+
+“Too bad about poor Reeves,” murmured Ballinger, as he held a lighted
+match in his cupped hands. “His life, however, would have been only a
+burden to himself and others, so in one sense it is just as well that
+he was shuffled off. For professional reasons I regret his death very
+keenly. I had hopes of being able to restore his brain to some degree
+of normal functioning. If I had succeeded I think he would have told us
+a most interesting story, and that, of course, was just what the other
+side feared. However, his actions told us a great deal the other night.”
+
+“When he seemed to recognize Doctor Latham in you?”
+
+“Exactly. To that extent the experiment was a complete success. It was
+Carlin’s idea, and the credit belongs to him. I merely carried out his
+suggestions, and I didn’t particularly relish the task.” He chuckled
+apologetically. “Well, the murder of Reeves is additional proof of
+the fact that we are fighting a crowd of very ingenious and utterly
+conscienceless scoundrels. Evidently they are directed by a master
+mind, a genius of the kind we often read about, but seldom meet. You
+will admit there’s a great deal of fascination about a rascal of that
+type, Cole?”
+
+Cole did not answer, but he remembered the magnetic tug he had felt in
+Doctor Latham’s presence.
+
+“I almost envy you the exciting times you will have tracking this
+master mind to his lair,” Ballinger went on. “We know some of the
+smaller fry in the crowd, Professor Carmody, for instance, but our
+efforts won’t lead anywhere until we have found the directing genius.
+And when we have found him, Cole, we will be face to face with an
+interesting character. Brilliant, resourceful, unscrupulous, and full
+of bewildering subtleties, the kind that kills without hesitation the
+moment his plans are interfered with. I dare say you have already
+suspected who he is?”
+
+Ballinger’s eyes shone with a fine glow of enthusiasm, but it was the
+unimpassioned enthusiasm of a scientist who dissects and analyzes.
+
+“Perhaps,” said Cole guardedly. “Haven’t you?”
+
+Ballinger smiled queerly, but the opening of the door and the
+announcement that dinner was served forestalled a reply. In the
+corridor they were parted by a stream of people, and Cole found an
+opportunity to speak a few words in Carlin’s ear. The lawyer nodded
+bewilderedly, like one receiving instructions which he does not
+understand. He knew Cole had a plan of some sort, but he could not make
+even a guess as to what it was.
+
+There were some twenty-five or thirty at the table. Cole found himself
+seated between Miss Brownell and Carlin. Inwardly he felt a tingling
+sensation, as he contemplated the bombshell he was about to explode
+among the diners, but his face showed no sign of it. Now and then he
+stole a glance down the two wings of the table. He liked the faces of
+the men with whom he was to work. They were an alert, keen-eyed lot,
+the kind of men Cole himself would have selected.
+
+“You are a judge of faces,” whispered Miss Brownell, leaning slightly
+toward him. “Who is the traitor?”
+
+Cole shook his head. That very question had already occurred to him.
+There was not one in the gathering who by his looks could be singled
+out as the traitor.
+
+“Whom would you pick?” he whispered back.
+
+Her glance ran quickly up and down the table. He could see that her
+woman’s intuition was at work. A queer gleam came into her eyes; her
+face hardened for a moment. He tried to trace her glance, but it was
+too late.
+
+“It wouldn’t be fair to tell, would it?” she said evasively. “I may be
+wrong, you know.”
+
+Cole only smiled. As nearly as he had been able to tell, her glance had
+rested for an instant somewhere near the center of the left wing of the
+table. He scanned the faces of the men seated there, but none of them
+impressed him unfavorably, and he wondered what Miss Brownell could
+have based her guess on.
+
+The dinner progressed by easy stages, and the scene which Cole had been
+rehearsing in his mind was drawing near. Carlin, seated at his right,
+looked nervous, and Miss Brownell’s usually vivacious manner seemed
+somewhat dampened. Finally the sauterne was opened and the waiters
+filled the glasses. Carlin cleared his throat.
+
+Noisy applause greeted the lawyer’s announcement that Cole had
+accepted the management of The Unknown Seven’s activities. Then Carlin
+proposed a toast, and it was drunk standing. Cole watched the faces
+of the men as they quaffed their wine. In several of them he saw a
+vaguely wondering look, telling him that their senses had registered
+an impression so faint that as yet their minds had not grasped it. He
+sipped his own wine, and he wondered whether he would have been able to
+taste the foreign substance if he had not known it was there.
+
+When Carlin finished, Cole got to his feet amid renewed handclapping.
+Somewhat bluntly he thanked them for the ovation, and then he veered
+sharply to the subject uppermost in his mind.
+
+“I wonder,” he said, “how many of you can look me straight in the eye
+and tell me that you are loyal to this organization.”
+
+A breathless hush followed. His very quiet tones had created a profound
+impression. In the next instant every pair of eyes in the room was
+leveled at him without wavering.
+
+“It seems to be unanimous,” he observed dryly. “One can lie, however,
+with his eyes as well as with his tongue, and I know that one among you
+is a liar.”
+
+Another period of silence followed, and then came a scraping of feet
+and exclamations of incredulity. Cole held up a silencing hand. His
+eyes were everywhere, noting each shifting expression in the startled
+faces before him.
+
+“One of you has proven false to the organization,” he declared in
+short-clipped accents. “I discovered it only a little while ago. I
+found positive proof, not only of the treachery, but of the traitor’s
+identity as well. He is at this table. He was one of those who only a
+few moments ago looked me straight in the eyes. What shall we do with
+him?”
+
+Once more came an electric hush. Cole had spoken quietly, but with an
+emphasis that carried conviction. He smiled faintly, as he met the
+startled glances of the diners. A slight trace of the foreign substance
+in the wine was still lingering on his tongue.
+
+“What shall we do with him?” he asked again.
+
+“There’s only one thing to do with a traitor,” muttered some one at
+the farther end of the table, and the suggestion was followed by a
+chorus of approval.
+
+“And that thing has already been done,” declared Cole with grim
+emphasis. “So that it may serve as a warning to others who may be
+tempted to betray us, the traitor will die right before our eyes.
+Inside one minute the poison that was put into his glass will begin to
+take effect.”
+
+Cole pretended to look at his watch, but his glance was gliding swiftly
+over the two long rows of faces. He had spoken rapidly, and yet with a
+quiet insistence, putting his astounding announcement into the fewest
+possible words. The effect he hoped to produce depended upon a quick
+assault on the guilty person’s mental faculties, shocking him off
+his balance before he had time to digest the statement. In the acute
+tension of the moment, the vague impression that he had received while
+sipping his wine would suddenly crystallize, and then, with the fear of
+death upon him, he could not help betraying himself.
+
+At least such was the psychological effect Cole had intended, and he
+had been reasonably sure that the test would succeed. Moments passed
+while he stood, watch in hand, glancing out of the tail of an eye
+at the faces around the table. Sixty seconds passed, and a look of
+diffidence crossed his features. Here and there an impatient mutter was
+heard. Carlin was looking up at him with an expression of thinly veiled
+disappointment. At length Cole snapped the watch shut. He smiled rather
+sheepishly.
+
+“The trick didn’t work,” he said disgustedly. “Yes, I might as well
+admit it was only a trick. The traitor was too clever to betray
+himself.” With that he sat down, well aware that he had made an
+unfavorable impression.
+
+“It was too thin, Cole,” whispered Carlin in his ear. “Too bad you
+didn’t consult me beforehand.”
+
+Cole nodded dejectedly. Then he felt Miss Brownell’s gaze on his face.
+He turned and saw a knowing twinkle in her eyes.
+
+“It was very clever, Mr. Cole,” she whispered. But for all that her
+face indicated she might have given him only a consoling platitude.
+“You saw, of course?”
+
+“Yes, I saw enough.” The sheepish grin still lingered on Cole’s lips.
+“And you guessed right. The traitor is sitting near the center of the
+left wing of the table. Doctor Ballinger is a very astute rascal. It
+took him only a fraction of a second to see through my little bluff. He
+is smiling behind his palm this very moment. We’ll just let him keep on
+smiling for a while, eh, Miss Brownell?”
+
+
+
+
+ CHAPTER XVI
+
+ GOLD
+
+
+After dinner Cole looked the picture of a man whose faith in himself
+has received a staggering blow. He seemed to take the outcome of his
+ruse very much to heart. He moved gloomily among the members of the
+organization, getting personally acquainted with a number of the men
+on his staff, and all the while he appeared to be making valiant, but
+not very successful, efforts to shake off his depression. Carlin did
+his best to gloss over the apparent frustration of the scheme, but Cole
+proved a hard man to console.
+
+Doctor Ballinger approached him after he had retired into a corner,
+and gave him a vigorous slap on the shoulder. “Don’t take it so hard,
+old man,” he said cheerily. “Know just exactly how you feel. It’s
+embarrassing to turn up a flivver right at the start, but don’t you
+mind. Better luck next time. Have a smoke.”
+
+“Thanks,” said Cole dejectedly, as he helped himself to a cigar from
+the doctor’s case. “What hurts me most is that I know I was right.
+Nothing is so humiliating to a man as to be sure of his facts and not
+be able to prove them. I know positively that there’s a black sheep in
+this fold. If I had worked the scheme properly——”
+
+“Tut, tut!” interrupted Ballinger. “Your scheme was all right in
+principle. You were simply out of luck, that’s all. The traitor, if
+you’re right in the assumption that there is such a creature among us,
+is probably a very slick customer. No doubt you had him scared stiff
+for a moment, but his emotional reaction didn’t last long enough for
+him to betray himself. He assumed that you were only bluffing. At any
+rate he saw that, having already drained his glass, nothing could be
+gained by making a show of himself. In other words his mind outstripped
+his emotions, and that’s where your psychology fell down. No matter!
+You’ll get him next time.”
+
+Cole walked away, a faint twitching at the corners of his lips. In
+the main Doctor Ballinger’s analysis had been correct. He had only
+forgotten to mention one little detail. Just as the traitor’s mind
+had outstripped his emotions, so had Cole’s alert glance outstripped
+both. For just an instant Ballinger had shown all the symptoms of acute
+terror. He had shaken them off with superb self-control, but not before
+Cole’s eye had registered his momentary confusion.
+
+The revelation that Ballinger was the traitor had given Cole a shock
+at first. The doctor was one of the last men in the organization whom
+he would have suspected of treachery. Having found him out, Cole saw
+no reason for apprising the doctor of the fact. He preferred to let
+Ballinger lull himself into a false security until he should show his
+hand more plainly. Neither did it seem advisable to Cole to take the
+other members into his confidence in regard to his discovery. It would
+be hard to keep a secret among so many, and the more hotheaded ones
+among them would probably demand drastic action.
+
+As inconspicuously as he could, Cole left the others and withdrew to
+the room that had been pointed out to him as his private office. It was
+small and comfortable and devoid of the drabness that characterizes
+the workroom of the average executive. There was a vase containing red
+roses on the desk, and he noticed that the pictures on the wall had
+been carefully chosen. He stretched himself out in the swivel chair and
+rocked in an experimental way. His glance fell on three white buttons
+affixed to the side of the desk. He pushed the one nearest him, just to
+see what would happen.
+
+The door opened, and in strode the biggest negro Cole has ever seen.
+
+“Who are you?” he inquired.
+
+“Sambo, sah.”
+
+“And what’s your job, Sambo?”
+
+“Just now mah bussiness is to answer dese heay bells, sah. Dat ain’t
+mah reg’lar job, though, but Rufus is done laid up in the hosspittle,
+and I’se takin’ his place.”
+
+“What happened to Rufus? Sick?”
+
+“Yas, sah. Mighty sick, sah.” Sambo grinned expansively. “You ought to
+know, boss, ’cause you made him sick yusself. Dat was an a’ful wallop
+you handed Rufus, sah.”
+
+Cole smiled reminiscently, as he recalled one of the numerous
+experiences that had enlivened his first visit to the establishment of
+The Unknown Seven.
+
+“Too bad about Rufus,” he remarked. “Now, Sambo, I want you to find
+Mr. McKendrick and ask him to come here at once.”
+
+“Yas, sah.” With a profound bow Sambo waddled out.
+
+McKendrick, one of the young operatives with whom Cole had chatted
+since the dinner, appeared after a brief wait. He had a clear eye, a
+whimsical expression about the mouth that had appealed to Cole on first
+sight, and a firmly molded chin.
+
+“Go into the main office,” Cole directed. “You will find a dictaphone
+in the ventilator shaft. The wire apparently runs out on the roof.
+Trace it to the other end, then report to me.”
+
+“Very well, sir.” As McKendrick walked out, Cole noticed with approval
+the easy swing to his shoulders. Once more he touched the nearest
+button, and Sambo appeared almost instantly.
+
+“Find Sloane and tell him I want him,” Cole directed.
+
+Sloane entered in a few moments. With his keen intellectual features
+and shell-rimmed spectacles he looked a good deal like a college
+professor.
+
+“Sloane,” began Cole, “I want you to go to the block in which Doctor
+Latham resides. Somewhere in the neighborhood, in a basement entrance
+across the street, perhaps, you’ll find a young chap of dilapidated
+appearance who answers to the name of Tony Pinto. He’s been watching
+the doctor’s house for the past twenty-four hours and must be sadly in
+need of food and sleep. Tell him I have sent you to relieve him.”
+
+“I understand perfectly, sir.”
+
+Cole gave him a few more instructions, and then Sloane withdrew. Again
+Cole pressed the button, this time to summon a man whom he instructed
+to make a thorough search all over the establishment for hidden disks
+and wires. When the man had gone, Cole leaned back in his chair and
+pondered. He had set the machinery in motion, but the hardest task he
+had reserved for himself. Something had to be done very soon about the
+body of Reeves. What to do with it was a problem that would demand all
+his resourcefulness. Too, a watch must be kept over Doctor Ballinger,
+and Cole did not like to delegate that business to any one else. He
+expected to learn a great deal from the unsuspecting doctor’s movements
+during the next twenty-four hours.
+
+He was deep in thought when a knock sounded on the door. In response to
+his rather brusque “Come in,” Miss Brownell entered.
+
+“I’ve been thinking,” she announced.
+
+“So I see,” said Cole, placing a chair for her. Miss Brownell, he
+observed, was one of the few women whom he had met who could wear a
+thoughtful frown becomingly. Where another woman’s forehead would have
+wrinkled, hers merely rippled.
+
+“You have been doing a lot of thinking yourself,” she remarked,
+regarding him with that curious impersonal glance of hers.
+
+“Yes, but mostly in the dark,” Cole admitted. “I’m pretty much in the
+same fix as the man who walks into a theater in the middle of the
+second act. The only thing that’s clear so far is that the principal
+actors in this drama seem to be doctors.”
+
+“You refer to Latham and Ballinger, of course. There is still another
+doctor involved.”
+
+“Still another? Who is he?”
+
+“In a sense he is the real instigator of the plot, although he died one
+hundred and thirty-eight years ago.”
+
+Cole blinked bewilderedly. “Sounds rather ghostly.”
+
+“His name was James Price, an English physician of high repute, who
+discovered a method of transforming baser metals into gold. You can
+read up on him in history or the biographical encyclopedias, if you
+like. He wrote a book entitled ‘An Account of Some Experiments,’ but
+it has been out of print a long time and copies are hard to obtain.
+Professor Carmody owns one of the few still in existence.”
+
+“Oh!” said Cole, elevating his brows. “So that’s what the mystery is
+about? But you don’t mean to tell me that sane men like Latham and
+Ballinger are dabbling in the exploded myth of alchemy?”
+
+“I do. And that myth, by the way, seems to die very hard, Mr. Cole.
+It’s been exploded and reëxploded since the dawn of history, and yet it
+keeps bobbing up every now and then.”
+
+Cole gave a little impatient shrug. “It’s rubbish,” he declared. “I
+have managed to forget most of the things I learned at school, but I
+seem to recall that modern science has absolutely established the fact
+that one element cannot be transformed into another.”
+
+She looked at him amusedly. “We women always smile when you men speak
+of absolute facts. The phrase is so delightfully characteristic of
+the sterner sex. And the world has moved since you went to school,
+Mr. Cole. Science has hedged and quibbled and reversed itself a good
+many times on the subject of the transformation of metals. It wasn’t
+so very long ago that some one discovered that radium can be produced
+from helium, or was it the other way round? Anyway, right there is an
+instance of the transformation of one element into another.”
+
+Cole opened his lips to speak, but seemed unable to find the right
+words.
+
+“I was telling you about James Price,” Miss Brownell went on. “He
+claimed to have discovered a method whereby he could transform sixty
+parts of mercury into one part of gold. He was rather secretive about
+his discovery and hedged it about with a lot of mystic hocus-pocus.
+About all that is definitely known is that a mysterious red powder
+figured prominently in the process. The red powder was mixed with
+mercury and fluid borax, and the concoction was then put in a crucible
+and stirred with an iron rod. The result was gold.”
+
+“The iron rod must have been a magic scepter,” suggested Cole dryly.
+
+“Perhaps; anyway the Royal Society of England got interested in Price’s
+experiments and made an investigation. A committee of England’s
+foremost scientists went to his laboratory, firmly expecting to expose
+Price as a faker or lunatic. I can imagine the long, bewhiskered faces
+of those learned old fogies when they put the gold through an assaying
+process and found that it proved genuine in every respect.”
+
+Cole’s pupils dilated a trifle, but he looked still dubious.
+
+“What I have told you is a matter of history, amply documented and
+supported by incontrovertible evidence,” declared Miss Brownell. “There
+can be no doubt but that Price produced a form of gold that proved
+genuine on assay. I am now coming to the strangest part of the story.
+Having solved this problem, that has tantalized scientific minds since
+the beginning of history, Price turned a sort of mental somersault.
+Just what happened to him has never become definitely known. Some
+still insist that he was a faker, despite the tests that were made.
+Others believe that his mind collapsed under the strain, and that he
+went insane. That seems to be nature’s way of punishing those who peep
+behind the curtain of the unknown, and Price was neither the first nor
+the last to go mad on the subject of gold. Still others think that
+gold became an obsession with him, a sort of monomania, and that he
+could not endure the thought of sharing his discovery with others. Then
+there are those who cling to the theory that his production of gold was
+nothing but an accident.”
+
+“What happened?” asked Cole.
+
+“The committee of scientists wanted to learn Price’s formula and asked
+him to repeat the experiment in their presence. Price refused on the
+pretext that his supply of red powders was exhausted. Shortly afterward
+he committed suicide by drinking laurel water. It has been generally
+supposed that his secret died with him. His book is somewhat vague
+in regard to the composition of the red powders. Repeated attempts
+have been made to learn exactly what they consisted of, but without
+success. Last year, however, Professor Carmody returned from abroad
+after browsing in the libraries of the Old World for many months. He
+brought back with him a number of faded and forgotten manuscripts, said
+to be in Doctor Price’s handwriting. Where he found them, and how he
+got possession of them we don’t know, but we do know that they gave him
+a clew to the secret which Price guarded so jealously.”
+
+“How do you know?” demanded Cole.
+
+“Our organization has eyes and ears everywhere. However, it was mostly
+through accident that we learned what was on foot. I shan’t bore you
+with the details. Carmody saw a chance to become enormously rich by
+manufacturing gold on a large scale, using Doctor Price’s formula. But
+he needed money to swing the enterprise, and so he guardedly approached
+a number of wealthy men with a scheme for multiplying their fortunes
+many times. Besides he knew that he lacked the executive ability
+required to engineer a project of such magnitude. He talked to Malcolm
+Reeves so engagingly that Reeves was smitten with the gold fever and
+supplied a great portion of the cash that he needed. No doubt he
+enlisted the assistance of other rich men in a similar manner. The lure
+of gold is a terrible thing, Mr. Cole.”
+
+“A curse,” said Cole. “But what about Latham?”
+
+“Latham is an extremely clever and very versatile man. Though he
+practices medicine he has dabbled in various sciences. Perhaps
+Carmody needed his assistance in solving some of the problems that he
+encountered in working out Price’s formula. However that may be, we
+know he has been very close to Professor Carmody for several weeks.”
+
+“Then you think Carmody is the moving spirit in the enterprise?”
+
+“No; Carmody merely supplied the formula and his scientific knowledge.
+He is a small man, physically and mentally, with a sharp, but narrow,
+intellect, and he is deficient in the qualities required to direct an
+enterprise of this sort. Knowing his shortcomings, he was willing to
+put the management of the project into stronger hands than his own.”
+
+“Latham’s, for instance?” asked Cole.
+
+“Or Ballinger’s. Both are very shrewd and energetic men, though I
+hadn’t thought of Ballinger in that connection until to-night. It is
+your job to find the master mind that is directing the operations of
+this gold-mad crowd, Mr. Cole. We know that they are already producing
+gold, or a substitute for gold, on a very large scale.”
+
+“Where?” inquired Cole quickly.
+
+“That’s another thing for you to find out. In some secluded spot in New
+York City or its environs there is a large and fully equipped plant.
+From snatches of conversation which we have overheard we know that it
+exists, but we haven’t been able to locate it. We also know that the
+conspirators feel confident that their product will stand every test,
+that it resembles natural gold in every respect. In order to eliminate
+all risk, however, they have decided to hold the gold in storage until
+the desired quantity has been manufactured. You can imagine what will
+happen when a golden flood is suddenly released and poured out over the
+country.”
+
+“A few men will become enormously rich over night, and the monetary
+system will be utterly disorganized. I suppose the ultimate result will
+be the worst panic the world has ever seen.”
+
+“That’s exactly what Mr. Carlin and the others think,” declared Miss
+Brownell.
+
+They sat silent for a time, neither looking at the other. Their minds
+were stunned by the contemplation of the golden havoc which their
+imagination pictured. Cole recalled the look of insane ecstasy which
+he had seen in Malcolm Reeves’ face. The words, “Pretty yellow,” which
+the insane man mumbled, suddenly assumed a vivid significance. He shook
+himself a little.
+
+“I suppose Reeves had a falling out with the others,” he remarked.
+“That’s why they first destroyed his mind and afterward killed him.”
+
+“Presumably.” Her eyes looked a little dim, as if they had gazed too
+long upon a dazzling vision. “It was about Reeves I was thinking
+just before I walked in here and disturbed you. I was wondering why
+Ballinger didn’t commit the murder. He had free access to the place and
+nobody had any suspicions against him. Why was it necessary to have the
+hunchback sneak in here and do it?”
+
+“I think the answer to that question is fairly clear.” Cole’s smile
+seemed to say that women, even the cleverest of them, were rather
+simple-minded at times. “The job had to be done by an outsider in
+order to conceal the fact that the conspirators had an associate in
+your midst.”
+
+“But they didn’t conceal it. The ease with which the hunchback got in
+and out proved clearly that he was assisted by some one on the inside.”
+
+“That’s so,” admitted Cole, somewhat abashed. “Well, then it’s quite
+likely that Ballinger balked at the job. Murder is pretty nasty
+business. It is a coarser crime than depriving a man of his reason.
+Many criminals of the intellectual type shrink from it.”
+
+“Maybe that was the way of it. There’s another thing that has been
+troubling me lately. Who do you think performed the operation on
+Reeves?”
+
+Cole stared at her for an instant. “It seems to be pretty well
+established that Doctor Latham was the man.”
+
+“Yes, I know that’s what they all seem to think. Their reason is that
+Reeves seemed to recognize Ballinger when he was made up to resemble
+Latham.”
+
+“It was more than recognition. The sight of Ballinger made up as Latham
+fairly terrified the poor man. I’ll never forget how he looked.”
+
+“But isn’t that a flimsy reason for supposing that Latham performed the
+operation?”
+
+Cole leaned out of his chair and regarded her closely, as if wondering
+whether her intuition was once more at work. “Can you imagine any other
+explanation for the way Reeves acted that night?”
+
+“Yes; can’t you?”
+
+Cole shook his head ponderously.
+
+“Just think about it,” she said, smiling faintly; then she rose and
+walked out of the room.
+
+For a long time Cole sat very still, with a thoughtful pucker across
+his forehead. Once, from force of habit, he reached for his pipe,
+frowning when he realized it wasn’t there. Now and then he bent a
+quizzical gaze on the chair which Miss Brownell had vacated.
+
+“What the deuce did she mean?” he mumbled. “What else is there to——”
+
+With a jerky motion he sat erect in his chair. He gave the desk in
+front of him a vigorous thump.
+
+“By Jove, she wins!” he declared. “There is another explanation. It’s
+beginning to look as though——” He checked himself, scowling. “But that
+only muddles the situation. What’s the good of an explanation that
+doesn’t explain. But I suppose a woman can’t see it that way. They’re
+all alike, from Toots down.”
+
+He shrugged as if to banish unprofitable speculations. He suddenly
+remembered that there had been weighty things on his mind when Miss
+Brownell interrupted his thoughts. He had given several orders to the
+men, and he had been studying what to do with the body of Reeves, and
+how he might make the most of his discovery that Doctor Ballinger was
+the traitor. He jumped from the chair as the physician’s name ran
+through his mind. For half an hour or more he had given not a single
+thought to Ballinger. He hurried from the office and crossed the
+corridor, but a glance into the smoking room reassured him. Ballinger
+was sprawled out leisurely in an armchair, evidently in the midst of
+an anecdote which he seemed to be relating with great gusto to his
+companion.
+
+Cole went farther down the corridor and rapped on the door to Miss
+Brownell’s private room. “Wish you would keep an eye on Ballinger for a
+while,” he whispered when she opened. She lifted her brows in a knowing
+way and nodded. In the main office he found Carlin bent over a stack of
+papers. The man seemed a veritable dynamo of energy.
+
+“I’ve been thinking about Reeves,” he said.
+
+Carlin looked up and took an obese cigar from his mouth. “What do you
+suggest?”
+
+“That we obey the spirit of the law and blink the letter. The ends of
+justice will be met if the murderer is convicted and punished. It won’t
+be necessary to drag all the embarrassing details into light.”
+
+“How can it be avoided?”
+
+“I have a plan, but, before I go any farther, I would like to see the
+body.”
+
+The lawyer got up. “I would have shown it to you when I took you over
+the place, but Miss Brownell was with us then, and you know how women
+are about such things.”
+
+He led the way from the room, and they went to the end of the corridor.
+There Carlin opened a door, and they stepped in. It was dark, and Cole
+could see nothing. He heard a slight scraping sound, as the lawyer ran
+his hand over the wall in search of a switch. Then a light flashed on.
+Carlin raised an arm and pointed.
+
+“There,” he said a trifle thickly, indicating a shape spread out on a
+cot at the farther side of the room.
+
+Cole walked up to the cot and looked down at the dead man. He jerked
+back a little as his glance fell on the lifeless face. Then he bent
+over the body and gazed fixedly into the rigid features. Finally he
+stood up and turned to Carlin, who had remained behind.
+
+“When did you last see the body?” he inquired, and his voice sounded a
+trifle husky.
+
+“Why, I think it was this morning. Yes, that was it, about ten o’clock
+this morning. Why do you ask?”
+
+“Because—— But see for yourself.”
+
+With a wondering glance at the detective, Carlin crossed the floor. He
+looked down at the motionless figure, and suddenly he shrank back a
+step. A husky exclamation sounded in his throat, then he slowly raised
+his eyes, and for a long moment the two men stared blankly at each
+other.
+
+“It—it isn’t Reeves!” stammered the lawyer.
+
+“No—it isn’t Reeves!” echoed Cole.
+
+
+
+
+ CHAPTER XVII
+
+ IN ROOM 2512
+
+
+Cole had recognized the dead man at a glance.
+
+It was McKendrick, the young operative whom he had instructed to trace
+down the dictaphone wire. That had been only an hour ago, and already
+death had blotted out the whimsical expression about the mouth that had
+attracted Cole to him from the first.
+
+“Shot through the head,” muttered Cole, noticing a crimson stain just
+above the left temple. “He hasn’t been dead more than fifteen or twenty
+minutes.”
+
+He turned and looked out through the crack of the open door. A laugh
+sounded in the direction of the smoking room. Perhaps Doctor Ballinger
+had just told another funny story. Cole closed the door.
+
+“This shows there are no limits to the rascality of those blackguards,”
+said the lawyer. “But I don’t see why they should kill McKendrick.”
+
+Cole explained the errand on which he had dispatched the young
+detective. “No doubt McKendrick made an important discovery of some
+kind,” he added. “That’s probably why he was killed. He must have been
+overpowered, either while getting his facts or on his way back here to
+report. Probably the latter; that would explain why the body was taken
+here. The murderer wanted to conceal his crime as long as possible, and
+for a temporary hiding place this room served as well as any other. We
+must find out whether Ballinger has been absent from the smoking room
+during the last hour or so.”
+
+The lawyer seemed dazed. “But the other body? What happened to it?”
+
+“You are sure it was here this morning?”
+
+“Positive.”
+
+“Could any one have taken it down the private elevator without being
+seen?”
+
+“Impossible. Even if such a thing could be done, which is unthinkable,
+it is a ticklish job to transport a body through the streets. It is not
+yet midnight.”
+
+“Is there any other exit?”
+
+“Only the stairs leading to the roof.”
+
+“Then it is a safe bet that the body of Reeves was taken out that way.
+From the roof it could have been slipped down a fire escape in the
+rear, and from there—Heaven only knows!”
+
+“But why should such a thing be done? What object could any one have in
+doing it?”
+
+“I don’t know, Carlin. I can only make a hazy guess. Being a lawyer
+you know better than I do that, with the body missing, it will be
+hard to prove the murder of Reeves. I believe the law covering murder
+cases provides that, when the _corpus delicti_ cannot be proven,
+the commission of the crime must be established by direct, not
+circumstantial, evidence. Isn’t that correct?”
+
+“Substantially, yes.”
+
+“And, as I understand it, nobody saw the crime committed. Consequently
+there can be no direct testimony in regard to the murder. It appears
+that the men we are fighting are playing a very shrewd game.”
+
+The lawyer tried to pull himself together. “But isn’t it your idea that
+the men who instigated the murder of Reeves are also responsible for
+McKendrick’s death?”
+
+“Presumably?”
+
+“Then why, after going to all that trouble to cover up the first crime,
+did they leave the evidence of the second murder in plain sight?”
+
+“Looks a bit contradictory, doesn’t it?” Cole squinted abstractedly at
+the form on the cot. It seemed as though the murderers of McKendrick,
+in placing the body in the identical spot where that of Reeves had
+lain, had gone out of their way to add a spectacular touch to their
+crime. “But you may be sure of one thing,” he added. “They had good
+reasons for doing what they did. There isn’t any doubt——”
+
+He stopped short, and Carlin gave him a puzzled look.
+
+“Yes, that must be it,” Cole went on in an undertone. “The reason for
+what they did is to be found in the one thing that differentiates the
+murder of Reeves from that of McKendrick.”
+
+“And what’s that?”
+
+“Reeves was operated upon before he was murdered; McKendrick was not.”
+
+Carlin seemed unable to follow this line of reasoning.
+
+“If there should be an autopsy,” Cole explained, “it might be
+discovered that an atrocious operation had been performed on Reeves
+before his death. Such an operation could have been performed only by a
+skilled surgeon. It would be deduced that the operation and the murder
+were perpetrated by the same parties. That would reduce the range of
+suspicion down to one class of individuals, surgeons. So, you see, the
+body of Reeves constituted a clew to the identity of his murderers.”
+
+Carlin gave him an admiring glance. “First rate!” he applauded. “I’m
+glad you are doing the heavy thinking for us.”
+
+“You would have seen it yourself if you hadn’t been upset to-night,”
+said Cole modestly. “By the way, it’s just as well not to let the news
+of this fresh outrage get out among the men at present. Wish you would
+show me the stairs to the roof.”
+
+They left the room, and the lawyer locked the door. A short distance
+down the corridor they met Miss Brownell, and Cole recalled that he had
+asked her to keep an eye on the physician. Her lips tightened as he
+briefly whispered what had happened.
+
+“Do you know whether Ballinger was absent from the smoking room for any
+length of time during the last hour and a half?” he added.
+
+“He went out for cigars,” said Miss Brownell. “He explained that his
+case was empty, and he smokes only his special brand. When he returned
+he accounted for his long absence by saying that most of the cigar
+stores in the neighborhood were closed.”
+
+“That explanation is worthy of the doctor,” said Cole. “It’s plausible
+and yet simple. A more involved one might have got him into
+difficulties, if he should have been checked up on it afterward. Please
+watch him, Miss Brownell. If by any chance he should leave, have one of
+the men follow him. Now, Carlin.”
+
+The lawyer and Cole stepped into the main office. Suddenly Cole seemed
+to recall something. He went to the ventilator shaft which contained
+the dictaphone that had cost McKendrick his life. He touched the disk,
+and a low mutter escaped him as he found that the wire had been cut.
+About a foot and a half of it was dangling from the disk. He turned and
+told Carlin what he had discovered.
+
+“Something made them suspicious,” he added. “They cut the wire so we
+wouldn’t be able to trace it.”
+
+“They did that after murdering McKendrick,” suggested the lawyer.
+
+“Without a doubt. McKendrick, if he were alive, could probably tell us
+where the wire terminated. Now we will have a look at the roof.”
+
+But the door opened just then, and the man who entered was the
+operative whom Cole had instructed to search the establishment for
+hidden dictaphones. He reported that he had found four in as many
+different rooms, but in each instance the wires had been cut. Cole
+thanked him and dismissed him.
+
+“It’s a safe bet that all those wires were cut within the last hour or
+so,” he told the lawyer.
+
+Carlin led him to the farther end of the office. There he opened a door
+and indicated a steep flight of stairs. He was about to proceed up the
+stairs, but Cole held him back.
+
+“Wait, Carlin.” Cole took an electric flash light from his pocket and
+turned the gleam on the steps. They looked as if they had not been
+swept in a long while. He stooped low to examine a number of marks in
+the thick layer of dust. Drawing a magnifying lens from his pocket
+and slowly moving the electric torch up and down, he made a careful
+inspection of the lower steps.
+
+“Two sets of footprints,” he declared. “One set is fairly large and
+broad-toed, a number nine and a half shoe, I should say. The other
+is a size and a half smaller, also narrower. This tends to show that
+McKendrick was followed when he came down from the roof.”
+
+“Why do you suppose he was permitted to leave the roof?” inquired the
+lawyer.
+
+“Because the murderer couldn’t aim in the dark. He wanted to make a
+sure job of it. Probably McKendrick didn’t know he was followed down
+the stairs. Likely as not the shot wasn’t fired until he got down to
+the main office. It’s even possible the murder wasn’t committed until
+he was out in the corridor. That would explain why the murderer chose
+the room at the end of the hall as a temporary hiding place for the
+body. If the shooting took place in the corridor, he had to drag or
+carry it only a few steps.”
+
+Cole pocketed his flash and lens, and they started up the stairs.
+
+“But wouldn’t the shot have been heard?” asked Carlin.
+
+“Not if the weapon was equipped with a silencer. The smell of the
+burned powder was probably sucked up very quickly by the automatic
+ventilators.”
+
+Carlin opened a trapdoor overhead, and they stepped out on the roof. Up
+there all was wind and gloom. Their footsteps creaked dismally against
+the gritty surface. All around them loomed the ghostly shapes of tall
+buildings. Masses of clouds hung scowling over their heads, and there
+was a suspicion of moisture in the air.
+
+Cole stepped to the fire escape in the rear, the lawyer following. They
+looked down over the parapet into a wide court flanked by murky walls.
+“Yes,” said Carlin, more to himself than to his companion, “the body of
+Reeves was probably carried down this fire escape. It could have been
+done.”
+
+Cole nodded. “I wonder,” he said abstractedly, “how far down it was
+carried?”
+
+“Have you any reason for supposing that it wasn’t carried clear down to
+the ground?”
+
+“No, only a hunch, and most hunches are ridiculous. They go contrary to
+facts and logic. But just now I am more interested in what happened to
+McKendrick. He must have discovered something very important to warrant
+the scoundrels killing him. I wonder what it could have been.”
+
+“The other end of the wire, of course.”
+
+“Something more than that, I think.” Cole gazed down the long stretch
+of flights and landings that composed the fire escape. “Criminals of
+that type never kill without good cause. Not because they shrink from
+murder on moral or humanitarian grounds, but because it is dangerous
+and inexpedient. McKendrick must have discovered something that—— By
+the way, Carlin, I suppose The Unknown Seven controls the renting of
+offices in this building? You told me once that it is property of the
+organization.”
+
+“It is, but the members individually have nothing to do with the
+management of the building. That is handled through a separate
+corporation. Why do you ask?”
+
+“No particular reason. Those infernal hunches are bothering me more
+than usual to-night. Suppose you wait here while I investigate.”
+
+Before the lawyer could answer, Cole had flung himself over the parapet
+and was gliding down the fire escape with the agility of a chimpanzee.
+On the first landing he stopped and once more took out his electric
+flash and magnifying lens. Then he turned to the window and carefully
+examined the frame in the neighborhood of the fastenings. Tiny marks,
+that had a fresh appearance, told him they had been tampered with not
+so long ago. McKendrick, following the winding course of the dictaphone
+wire, had probably passed through this same window.
+
+In a few moments Cole was inside. Before him stretched a long hall with
+doors on either side; but the one to his left was the only one that
+interested him. He looked for a moment at the numerals 2512 and the
+lettering on the frosted pane. Once before in the past twelve hours the
+same sign had confronted him. While tracing Englebreth’s movements in
+the early afternoon Cole had come to this same door, and then he had
+turned back in the belief that nothing could be gained by going farther.
+
+“Bureau of Civic Research,” he read, wondering whether McKendrick had
+followed the course of the wire through this same door. Cole had no
+particular reason for thinking so, for at least twenty other doors
+opened into the same hall. Yet, in view of Englebreth’s apparent
+familiarity with Cole’s movements during the past few days, he could
+not help wondering. If the dictaphone wire had extended into suite
+2512, then the source of Englebreth’s information was clear.
+
+But the theory explained nothing else, and Cole had no proof that the
+wire had entered the office of the Bureau of Civic Research. His only
+clew was the scratches on the window frame, and they merely indicated
+that McKendrick had been on this floor. For all Cole knew, the young
+operative might have continued his search farther down.
+
+Yet the door continued to tantalize him. With a glance over his
+shoulder to see if perchance a watchman was near, he tried the knob.
+As he had expected, the door was locked, but he stooped and looked
+closely at the little circle of brass that formed the outer portion
+of the spring lock. The hall light was dim, so he once more took out
+his electric flash. Close to the center of the circle, just beside
+the keyhole, he saw a slight scratch. It was almost certain now that
+McKendrick had picked the lock and passed through the door.
+
+From his pocket Cole drew a bunch of carefully selected keys. Soon the
+door was open, and he walked in and quickly closed it behind him. Then
+he took out his flash, not thinking it safe to turn on the light, and
+made a swift inspection of the premises.
+
+There were two rooms, a larger and a smaller one. After a glance over
+the floor and walls, Cole’s face fell. The thing which he had vaguely
+and without much reason expected to find was not there. It was just
+an ordinary suite of offices, containing the ordinary set of office
+furniture. A glance into the filing cabinets left him in no doubt as to
+the bona-fide character of the Bureau of Civic Research.
+
+On one of the desks in the inner office were several typewritten
+letters. At the top of each sheet were printed the name of the concern
+and a list of its officers, and he noticed that Englebreth was
+mentioned as one of the honorary vice presidents. The letters had, in
+fact, been dictated by Englebreth, for in the lower left-hand corner
+of each one were the initials HE-MS. No doubt he had dictated them
+that afternoon and expected to sign them later. A glance told Cole
+that they pertained to political matters and dealt in detail with the
+availability of a certain candidate for alderman.
+
+He put the letters down. They confirmed a theory that he had formed
+that afternoon that the Bureau of Civic Research was a hobby of
+Englebreth’s. Like many another rich man, his former client presumably
+felt the need of justifying his existence in some way. Cole felt
+satisfied on that point, but there were other doubts in his mind.
+It was just possible that the rooms of the bureau were being used
+clandestinely by persons who were in the habit of sneaking in there
+at night. Being close to the fire escape they were within easy
+reach of the headquarters of The Unknown Seven. The guess was rather
+far-fetched, but it seemed to explain several things.
+
+Knowing that Carlin was waiting for him on the roof, and seeing that
+his quest was unavailing, Cole put out his flash and moved toward the
+door. He had advanced only a few steps when something prompted him to
+halt. A vague impression that some one had stopped outside the door
+came to him. He tiptoed to a corner of the room and waited. Presently
+he heard a key grate in the lock, and then the door came open. It was
+beginning to look as though his suspicions had been correct, that
+persons other than the regular tenants were visiting the offices at
+night.
+
+A light appeared in the outer room. Next he heard some one move across
+the floor. From his position, in the corner of the inner office, Cole
+could not see who the newcomer was, and he did not care to make his own
+presence known just yet.
+
+The footsteps were coming toward him, and Cole pressed close to the
+corner, as a figure appeared in the doorway. The footfalls gave him a
+queer sensation. He thought he recognized the plopping little sounds,
+suggestive of a walker who, instead of putting most of his weight on
+his heels, places his entire foot on the ground at once.
+
+While still within the doorway the newcomer reached out a hand and
+touched a switch on the inner wall. In the light that suddenly
+appeared, Cole saw that he had identified the footfalls accurately. The
+man was Professor Carmody, and Cole’s eyes narrowed as he recognized
+him. The scientist wore a faded silk hat and a long overcoat, just
+as Cole had seen him when he walked into Doctor Latham’s house the
+day before, and under his arm he carried a large umbrella. He walked
+straight to the middle of the office before he saw Cole, and then he
+stopped so abruptly that it seemed as if his gaunt form would topple
+over.
+
+“Hello,” he said, staring out of his small, mouse-colored eyes. His
+long nose, much too large for symmetry, was turned up, and his parted
+lips showed two rows of yellow teeth. He was plainly embarrassed, and
+to conceal the fact he grinned ostentatiously.
+
+“Good evening, professor,” said Cole, stepping forward. Though this was
+their first meeting at close quarters, he had reason to believe that
+Carmody knew who he was. Miss Brownell, he recalled, had told him that
+the professor was well aware that Cole had been watching him from a
+distance for some time.
+
+“Are you connected with the Bureau of Civic Research, professor?” Cole
+went on.
+
+“In a way, yes,” said Carmody. He had a very thin voice that had a
+habit of rising to a shrill pitch, or falling to a faint murmur,
+without regard to what he was saying. He peered at Cole in an
+apologetic way. “I don’t believe I’ve had the pleasure of meeting you
+before.”
+
+“Don’t you know who I am?”
+
+Carmody wagged his head. “I can’t say that I do.”
+
+“Too bad, professor. I was in hopes that you would remember me. One
+doesn’t like to ask favors of strangers.”
+
+“Favors?” Carmody’s face took on a forbidding frown. “You wish to ask a
+favor of me?”
+
+“Just a slight one. There is a book in your library that is very hard
+to obtain, and I am very anxious to read it. The author is one James
+Price.”
+
+The professor looked at him hard and long. “You are mistaken,” he said
+finally in a very low tone. “The author whom you mention is not in my
+collection. May I ask what led you to think that I own the book in
+question?”
+
+“A little bird told me.”
+
+“You take your information from curious sources.”
+
+“One has to, sometimes. By the way, professor, aren’t you keeping
+rather queer office hours? It is, let me see, a quarter past one.”
+
+“I might ask the same question of yourself.”
+
+“That’s so; you might.”
+
+“I might also ask what you are doing here. It is my impression that you
+do not belong on the premises.”
+
+“Hope I am not in the way. Please go ahead and attend to whatever
+business brought you here.”
+
+But Carmody seemed in no hurry. Cole could not know whether it was
+because he had abundant leisure on his hands, or because he did not
+care to attend to his business in another man’s presence, but it was
+evident that the professor was not disposed to gratify his curiosity.
+Now and then his mousey little eyes moved furtively about the room,
+and once they rested in a designing way on one of the flat-top desks.
+Cole, following his glance, was vaguely puzzled.
+
+“Pardon me, but aren’t you trespassing?” inquired Carmody after a pause.
+
+Cole folded his arms and smiled genially. “You are not going to order
+me out, I hope?”
+
+“Suppose I should do that?”
+
+“I would overlook your rudeness and refuse to take the hint. If you
+insisted, I might invite you to try to put me out. If you should make
+such an attempt and fail at it, I would suggest calling the police to
+your assistance. But I don’t think you will go that far, professor. You
+might be called upon to explain your own presence here, and that would
+prove embarrassing.”
+
+There was a calculating gleam in Carmody’s eyes. Cole, with a picture
+in his mind of Carlin waiting for him impatiently on the roof, was
+anxious to bring the interview to a climax. He had no intention of
+leaving until he had learned the object of the professor’s visit.
+
+Once more Carmody looked stealthily about the room, and again his
+glance rested on the desk. Cole’s lids narrowed, as he perceived that
+the desk, which seemed to be the object of the professor’s interest,
+was the one on which lay Englebreth’s unfinished letters. There
+were three other desks in the room, so it seemed odd that Carmody
+should center his attention on this particular one. Cole had already
+discovered that the drawers were empty, and that the desk contained
+nothing except the papers lying on top. Strange though it seemed, it
+looked as though the scientist’s visit to the office at this late hour
+was in some way concerned with the letters Englebreth had dictated that
+afternoon.
+
+The theory seemed rather far-fetched, so Cole decided to test it. He
+moved leisurely about the room a few times, then stopped before the
+desk at which the professor’s sly glances had been directed. In a
+casual manner he picked up the letters, looked hastily at two or three,
+then folded them across the middle and stuck them into his pocket.
+
+He knew, even before the letters reached his pocket, that his suspicion
+had been well founded. Carmody had watched his every move with growing
+excitement. His expression had changed from bewilderment to dismay, and
+finally his face took on a look of sullen determination.
+
+“What are you doing with those letters?” he demanded.
+
+“Taking them home,” said Cole easily, at the same time moving toward
+the door.
+
+“Wait!” said the professor sternly.
+
+Cole turned around and watched him with amusement. “What’s the matter?”
+he asked innocently. “What are these letters to you?”
+
+“You shall not leave this office with them. Give them to me at once.”
+
+He reached out a hand, and Cole saw that it trembled. Evidently he
+was desperately intent upon obtaining possession of the letters. Cole
+was at a loss to understand, for he knew that the epistles dealt with
+political affairs that could be of no vital concern to a man like the
+professor.
+
+“Don’t excite yourself,” he said quietly. “There’s nothing in these
+letters that would interest you. They contain nothing but dry political
+rot. What do you care about that sort of thing?”
+
+“Are you going to surrender them?” demanded Carmody, and the words
+sounded like an ultimatum.
+
+“I’ll promise to consider it if you will tell me why you want them.”
+
+The professor regarded him queerly. A look of bewilderment crossed his
+sullenly determined face. His crafty little eyes seemed to be trying to
+read Cole’s hidden thoughts. “Why pretend you don’t know?” he asked;
+then, in wheedling tones: “Come now! The joke has gone far enough. I
+know you are only trying to tease an old man. The letters, please.”
+
+Cole shook his head. Carmody’s very insistence upon obtaining the
+letters was reason enough why Cole should not give them up. Once more
+he started for the door, but a sharp “Wait!” interrupted his progress.
+
+Cole turned slowly and looked into the barrel of a pistol in Carmody’s
+hand.
+
+“My dear friend,” said the professor in his softest, lowest tones,
+“please do not force me to take drastic measures. It would grieve me
+exceedingly to have to deal harshly with you. The letters, please!”
+
+
+
+
+ CHAPTER XVIII
+
+ THE LIGHT IN THE WINDOW
+
+
+Cole’s only response to Professor Carmody’s soft-spoken ultimatum was a
+smile. He knew that the scientist was the kind of foe who is the most
+dangerous when he uses his gentlest tones. It struck him as droll that
+he was risking his life for the sake of a few letters which, as far as
+he could see, he could put to no earthly use. He would not know what
+to do with them even if he should be able to depart with them safely.
+It was only Carmody’s earnestness in the matter that convinced him the
+letters must have a hidden significance.
+
+“Well, professor,” he said easily, “it looks like a deadlock. I don’t
+want to give up the letters, and you seem in no hurry to shoot.”
+
+The professor smiled still more blandly and took a tighter grip on the
+pistol. Cole believed he would shoot rather than see him depart with
+the letters. There was a certain grimness about the gaunt form and the
+sallow face which warned him that Carmody was playing a desperate game
+for high stakes. As often happens in tense moments, his mind turned to
+trivial things. He pictured Carlin waiting peevishly on the roof. He
+imagined Ballinger in the midst of another humorous yarn. A ludicrous
+vision of the hunchback, chained to the operating table in Doctor
+Latham’s house, flitted through his mind.
+
+But the pistol in Carmody’s hand baffled him. He felt no fear, but
+neither did he care to throw his life away needlessly. Once before in
+the past forty-eight hours he had looked into the muzzle of a pistol,
+but that one had been in Doctor Latham’s hand. He had laughed then
+and dared the physician to shoot, knowing that Latham, whatever other
+villainies he might be guilty of, was not the type that can shoot down
+a defenseless man in cold blood. He was too proud and high-spirited for
+that. With Carmody it was different. The professor was made of coarser
+stuff. He was not hampered by considerations of chivalry and fair play.
+He would shoot as soon as Cole’s back was turned.
+
+And so he restrained the impulse to laugh in the professor’s face and
+walk away. He preferred to bide his chance and watch for a sign of
+wavering in the hand that held the pistol. Growing tired of waiting, he
+decided to try a little stratagem that he had found successful in the
+past. It was a simple trick and based on one of the many queer antics
+of the human mind.
+
+He looked away from the pistol and began to gaze fixedly at a point on
+the opposite wall. Moments passed and grew into minutes, and still he
+stared rigidly, not a muscle in his face moving. His eyes were slanting
+upward, at a level of about a foot and a half above the professor’s
+head. The latter could not see what he was looking at, for he dared
+not turn his head, knowing that Cole would jump the moment he did
+so. At first he was mildly puzzled. Then his face showed signs of
+bewilderment. His curiosity changed into nervous concern.
+
+By and by he seemed plainly worried. It was evident that Cole’s fixed
+and silent scrutiny of something which the professor could not see was
+seriously affecting his nerves.
+
+Cole’s rapt expression did not change in the slightest degree. He just
+looked and looked at that blank point somewhere behind the professor’s
+back and just above his head. Carmody grew more and more disconcerted.
+A tension, which he was doing his best to check, was taking hold of
+him. He shifted from one foot to the other. A sense of something weird
+and unaccountable was stealing over him, despite his scientific poise
+of mind.
+
+At last came the chance for which Cole had waited. It was merely an
+uneasy flicker in Carmody’s eyes, accompanied by a slight turn of
+the head. It was not much, but Cole knew that, for the moment, the
+professor’s mind was diverted from the pistol. It was risky, but he
+might not get another chance. He flexed his muscles, and leaped, first
+to one side, then straight at Carmody, wrenching the pistol from his
+hand.
+
+A squeallike cry broke from the professor’s lips. Cole chuckled as he
+ran. The scientist started in pursuit, but Cole slammed the door in
+his face. In another instant, putting the pistol in his pocket, he was
+climbing through the window. Soon he was hurrying up the fire escape. A
+dark figure, with coat tails flapping in the wind, hastened toward him,
+as he swung over the parapet and landed on the roof.
+
+“Where on earth have you been?” asked Carlin reproachfully. “I was just
+on the point of going down to look for you.”
+
+“Is there a man on the staff who understands ciphers?” inquired Cole,
+taking the lawyer’s arm and hurrying him down from the roof.
+
+“Ciphers? Why, yes. Findlay Abbott is one of the best cipher experts in
+the country. What do you want of him?”
+
+“Find him and send him to my office,” said Cole hurriedly. Leaving the
+bewildered lawyer several paces behind, he ran down the corridor and
+entered his office. He had been there only a few moments when Abbott, a
+fat and pink-faced little man, trundled in. Behind him walked Carlin.
+Cole took the letters from his pocket and handed them to the expert.
+
+“See if you can make anything out of these, Abbott,” he directed. “All
+I know about them is that they are so important to one man that he was
+ready to shoot me on account of them. They may be in code.”
+
+Abbott looked as though he relished the task. He sat down, wiped his
+spectacles, and fell to work. In the meantime Cole told the lawyer of
+the episode in room 2512.
+
+Carlin’s eyes popped as he listened. He glanced with keen interest
+at the papers under Abbott’s nose. “You don’t think the offices of
+the Bureau of Civic Research are the headquarters of the gang we are
+fighting?”
+
+“No,” said Cole thoughtfully. “In the morning you might inquire of
+your agent how long the bureau has been located there. From what I
+saw, though, it looked as though the concern was on the square. It’s
+more likely that certain parties are using the offices as a listening
+post, because of their close proximity to this establishment. Knowing
+that we are fighting them, those fellows naturally want to find out how
+much we know and what our plans are. I have a strong suspicion that the
+dictaphone wires ran into the rooms below. What do you make of those
+letters, Abbott?”
+
+But Abbott was too deeply engrossed in his task to hear the question.
+The other two watched him in silence for a time. His puckered brow told
+that the letters presented a knotty problem. Finally he looked up.
+
+“No code here,” he declared. “These are just ordinary letters.”
+
+“Sure of that?” demanded Cole sharply.
+
+“As sure as one can be of anything. I’ll wager my salary for the next
+ten years that these are just plain letters.”
+
+“Then why did Carmody——” Cole suddenly gave the desk a resounding
+thwack. A light of comprehension dawned in his eyes. “I take my hat
+off to the professor. He is a slick little trickster. He wanted to get
+me away from there, having private business to attend to, and so he
+pulled the wool over my eyes and made me think that these letters were
+a matter of life or death. Carlin, I’m a boob!”
+
+He bounded from the office, leaving the lawyer and Abbott to stare
+at each other. He was angry, but only with himself. For the crafty
+professor he felt an unwilling admiration, but he was also determined
+not to let Carmody have the last laugh.
+
+The discovery that Englebreth’s letters were genuine had given him a
+sharp mental jolt. A suspicion had been gradually assuming shape and
+clarity in his mind, but the cipher expert’s report had uprooted it
+completely. All that those letters now meant to Cole was a wasted hour
+and a sense of humiliation.
+
+He hurried up to the roof, then down the fire escape, and soon he
+stood once more outside the door of room 2512. Carmody had had ample
+time to dispose of whatever business had brought him there, but it was
+just possible that he had not yet left, so Cole entered as quietly as
+he could. The moment he closed the door behind him he knew he was too
+late. The light that appeared at his touch on the button revealed two
+empty rooms.
+
+Cole moved forward, looking sharply over walls and behind furniture.
+Perhaps Carmody had accidentally left some clew to his mysterious
+errand. It was even possible that Cole might get an inkling as to the
+discovery that had cost McKendrick his life. He searched carefully, but
+at first with no results. There were fresh, but very faint, footprints
+on the floor, and he could easily locate the spot where he and Carmody
+had stood, while the professor was pointing the pistol at him. Which
+way had Carmody turned after Cole left the offices? The footprints
+reached to the door and then back into the inner office. Evidently
+Carmody had locked himself in before attending to his errand. With some
+difficulty Cole traced the faint marks across the floor, muttering a
+short exclamation when he found that they led straight to the safe,
+standing in a corner of the room.
+
+Cole had given the safe only a cursory glance on his previous visit
+to the office. Carmody’s entrance had prevented him from making a
+more careful examination. Now he saw that the safe was one of the best
+and latest makes. There was a look of freshness about the blue steel
+surface and the bright nickel trimmings which suggested it had not
+been there long. He remembered that this particular brand of safe, in
+addition to its other advertised merits, was supposed to be air-tight
+and absolutely burglar proof. It seemed rather large for a concern
+whose affairs were transacted in two small rooms, but, perhaps, it had
+been selected with a view to growing needs.
+
+The course of the footprints made it plain that Carmody’s errand had
+been related to the safe in some way, but that was as far as Cole’s
+deductions reached. Whether the professor had removed something from
+the steel box, or put something in, he had no means of knowing, and the
+locked door prevented him from gratifying his curiosity on that point.
+It did not stop him from exercising his imagination, however. With a
+grim nod and a tightening of the lips he made a guess in regard to
+Carmody’s business with the safe.
+
+There was nothing more he could do for the present, so he made his
+way back to the headquarters of The Unknown Seven. In the hall he met
+Carlin.
+
+“Well?” asked the lawyer. “Found out anything?”
+
+“The more I find out about this case the less I know,” confessed Cole.
+“All the same, I think I know what it was McKendrick saw that cost him
+his life.”
+
+Carlin’s brows came up.
+
+“But I’m not going to tell you what it was,” Cole added quickly. “I may
+be mistaken, you see, and I don’t propose to jeopardize my reputation
+with you. By the way, there’s a new safe in number 2512, as nifty an
+article of that kind as I ever saw. Pretty good size, too. Big enough
+for a man of your dimensions to sit down in, Carlin.”
+
+“You’re not going to ask me to crawl into it, I hope?”
+
+“No, nothing like that. I just have a hunch that in the morning that
+safe is going to be taken out of 2512.”
+
+“Anything unusual in that?”
+
+“Nothing at all, and that’s just what certain parties are counting
+on, I think. There are times when it is expedient to do the unusual
+thing under cover of the usual. I want you to detail a man to see what
+happens to that safe, Carlin.”
+
+The lawyer nodded, but in the next instant his eyes opened wide in
+astonishment. “You don’t think that——”
+
+“As I said before,” Cole interrupted, “I don’t care to risk my
+reputation on a guess that may prove unfounded. Seen anything of
+Ballinger lately?”
+
+“Not for half an hour or so. Been busy in the main office.”
+
+Cole gave him a keen glance. “What’s the matter, Carlin? You look
+worried.”
+
+The lawyer forced a smile. “It’s just a—a premonition. I guess that’s
+what you would call it. I have a feeling that the gang knows we are
+closing in around them, and that they are getting ready to cash in. We
+must strike quickly, or it will be too late.”
+
+“I don’t know but what you are right. I’ve felt something of the same
+kind myself. We must not only strike quickly, but with both fists.” As
+if he had meant it literally, Cole looked down at his clenched hands.
+
+“But where, Cole? Where are we going to strike? We don’t know who the
+leader of the gang is. That is, we can’t be sure. We don’t know where
+the plant is located. We don’t even know——”
+
+“You make me dizzy,” said Cole with a chuckle, and then he turned
+abruptly and walked into his private office. There he pressed a button,
+and in a few moments Sambo entered.
+
+“Ask Miss Brownell to step in here,” Cole told the big negro.
+
+Sambo’s eyes opened wide, showing a generous expanse of white. “Why,
+she done lef’ a hour ago, sah. She went out in a mighty rush, too.”
+
+“Sure of that, Sambo?”
+
+“Course I’s sure. I seed her mahself. It was just after Doc Ballinger
+lef’, sah.”
+
+“Doctor Ballinger?”
+
+“Yes, sah. The doc looked lahk he was wurried. The wurriedest man I
+eveh seed, sah. He tried not to let on, but he didn’t fool mah a-tall,
+sah.”
+
+“And you say Miss Brownell left shortly afterward?”
+
+“Yes, sah. Not more’n a minute, sah.”
+
+Cole jumped up from his chair. For a moment he stared at the gigantic
+negro, then waved a hand in dismissal. He had instructed Miss Brownell
+to put one of the men on Ballinger’s trail, in case the physician
+should go out. Now it seemed evident that the girl herself had started
+out to shadow the doctor. Cole could only hope that her audacity would
+not lead her into trouble. His acquaintance with women had been only
+casual, and he had an impression that they either fainted in a crisis,
+or else burst into tears. Miss Brownell was, of course, a variant from
+the usual type, but just the same——
+
+Cole sat down again. After all, he could do nothing for the present,
+and Miss Brownell seemed to have a surprising capacity for taking care
+of herself. He would stay close to the telephone, and, in due time,
+she would undoubtedly call him up. He waited, but the instrument at
+his side remained tantalisingly silent. When at length it shrilled a
+summons, he jumped nervously.
+
+But the person calling was not Miss Brownell. Instead, it was Sloane,
+the operative whom Cole had detailed to watch Doctor Latham’s
+residence. Latham and the hunchback had been far from his mind for
+several hours.
+
+“What is it, Sloane?” he asked quietly.
+
+Sloane reported that for the last hour a mysterious light had appeared
+at intervals in one of the windows of the doctor’s house. It might mean
+anything or nothing, and Sloane did not know what to make of it, so he
+was telephoning in for instructions.
+
+“Stay where you are,” Cole told him. “I’ll be with you in a little
+while.”
+
+For a few moments longer he sat at the desk, his mind working quickly.
+It was just possible that at Latham’s house he would find some clew to
+the movements of Ballinger and Miss Brownell. There was a fog in his
+mind, the result of too many conflicting developments, but there were a
+few things that seemed clear.
+
+Soon he was out on the street. In less than half an hour he reached
+the corner nearest Latham’s house and walked east on the opposite side
+of the street. He cast sharp glances into the shadows along the row of
+buildings. Suddenly he stopped. “Sloane,” he said in a low tone.
+
+The scholarly looking operative stepped out of a gloomy doorway. “Glad
+you came, sir,” he whispered. “Things look queer.”
+
+“What about the light you mentioned?”
+
+“It comes and goes, every two minutes or so. Look! There it is!”
+
+He pointed to a window on the second floor of the physician’s
+residence. A small, flickering light had just appeared. It wavered
+for a few moments, then faded out. The two men waited in silence, and
+presently the mysterious light came back. All the other windows were
+dark, and the solitary glow had an eerie look.
+
+“Stay here,” said Cole. “Don’t move unless I signal you by whistling
+three times from one of the windows.”
+
+Briskly he crossed the street. A bunch of skeleton keys rattled in his
+hand, as he vanished from sight in the dark basement entrance.
+
+
+
+
+ CHAPTER XIX
+
+ A WARNING
+
+
+Very softly Cole crept up the stairs. On the ground floor he stopped
+for a moment and listened. A heavy silence seemed to hover over the
+entire house. He stole up another flight of stairs and turned toward a
+door in front. The knob turned noiselessly in his hand, but the door
+was locked. He stooped and tried to peep through the keyhole, but he
+could see nothing.
+
+A few moments passed; then a slight scratching sound, like that
+produced when a match is struck, was heard within. At the same time a
+faint glow was visible through the keyhole. It lasted for ten seconds
+or so, and then all was darkness again. It was evident now that the
+intermittent glow which Cole had seen from the sidewalk had been
+produced by some one striking a number of matches.
+
+Suddenly he stood erect, listening. For a moment he thought he had
+heard a slight sound, coming from somewhere below, but apparently he
+had been mistaken. He had entered so quietly that it did not seem
+possible Doctor Latham’s sleep could have been disturbed by his
+movements. Again he fixed his attention on the door, for once more
+a scrrrrch came from the room. Through the keyhole, just before the
+fluttering light went out, he caught a glimpse of the hunchback.
+
+Cole was puzzled. What could the hunchback be doing, and what did
+the frequent striking of matches mean? He waited, uncertain what to
+do, but strongly tempted to open the door with one of his skeleton
+keys. Moments passed, and he listened in vain for further repetitions
+of the scratching sounds. Instead, he heard what sounded like a
+half-suppressed chuckle. Evidently the hunchback had found something
+that pleased him. A faint tinkle came through the keyhole, followed by
+a louder sound, like that of a heavy object being dragged across the
+floor. Then silence.
+
+Cole felt in his pockets for his bunch of keys, but he quickly withdrew
+his hand and cast a glance over his shoulders. This time he knew he
+was not mistaken. Some one was moving about on the floor below, but
+so softly that Cole’s keen ears detected only a faint suspicion of a
+sound. His eyes darted to left and right in search of a hiding place,
+but the best he could find was the corner back of the stairway railing.
+He pressed against the wall and crouched low.
+
+Some one was coming up the stairs. He was determined to learn as much
+as he could before he made his presence known. The meager light from
+the little electric bulb in the ceiling revealed a sweep of bald
+cranium, by which he easily identified Doctor Latham. Perhaps he had
+been awakened by the hunchback’s movements, or perhaps Cole’s entrance
+had partly aroused him, and he had just now become fully awake.
+
+The doctor swept past him without a glance in his direction and moved
+straight toward the room occupied by the hunchback. There he stopped,
+took a key from his pocket and unlocked the door. He pushed it open
+and stood in a listening attitude. Even from his remote position in the
+rear of the hall, he could hear a lusty snoring. It was strange, since
+he knew that the hunchback had been wide awake only a few minutes ago.
+Evidently the fellow was up to a ruse of some kind.
+
+Suddenly Latham turned and walked quickly toward the rear. For a moment
+Cole thought he had been discovered, but the doctor took only half a
+dozen steps down the hall. Standing on the stairway railing he removed
+the electric bulb from its socket in the ceiling, then entered the
+hunchback’s room. The hall was now dark, and Cole thought it safe to
+come forward. He reached the door just as a light appeared within.
+Peeping through the crack between the door and the jamb he saw that the
+physician had attached the bulb to a wall fixture. Now he was standing
+beside the operating table to which the hunchback had been linked for
+the past twenty-four hours, leaning over the motionless figure lying on
+it.
+
+He mumbled something beneath his breath, then gave the hunchback’s
+shoulder a vigorous shaking. The snoring stopped. The fellow sat up
+with difficulty and rubbed his eyes with his free hand.
+
+“You needn’t pretend,” said Latham. He was arrayed in the same dressing
+gown in which Cole had seen him once before. “I know you haven’t been
+sleeping. Where did you find these matches?”
+
+He pointed to a litter of charred stubs on the floor. The hunchback
+eyed him stolidly and shrugged his misshapen shoulders.
+
+The doctor’s glance went to an old battered safe in a corner of the
+room. He stepped up to it and tried the lock.
+
+“Thought you might be tempted to while away the time by investigating
+this old safe of mine,” he declared. “I removed the bulb on purpose, so
+you wouldn’t make much headway with it. Not that you would have found
+much if you had opened it, only a few papers.”
+
+Again he gazed at the charred fragments scattered over the floor. Cole,
+looking through the narrow crack, saw a puzzled frown on his bearded
+face. The room was small, and the conglomeration of articles in it
+suggested it was used in part for storage purposes. The scattered match
+stubs perplexed Cole as much as they did the doctor.
+
+“There might have been a box in one of the bureau drawers,” muttered
+the physician. “I suppose that’s where you found them. I don’t see,
+though, what pleasure you derive from burning up a lot of matches.”
+
+Cole was watching the hunchback’s face. A look of sly satisfaction
+lurked in the sallow features. Once the fellow bent a squinting glance
+on some object across the floor, but all Cole could see at that
+particular point was a dilapidated trunk. His bewilderment grew. The
+scene between the physician and the hunchback was not exactly what he
+might have suspected. He sensed a hidden element in it. He was aware of
+a curious strain and tension in the air.
+
+“I thought I heard you drag the table over the floor,” remarked the
+doctor. “You were not doing it just for exercise. What was your idea?”
+
+Again a look of secret elation crossed the hunchback’s face. He jingled
+the steel links that held one of his hands to the table.
+
+“Aw, can’t a guy move about a bit if he wants to?” he asked. “Sittin’
+still in one place all the time gets on a feller’s nerve. I didn’t do
+no harm.”
+
+The physician regarded him searchingly. Evidently he, too, had seen
+the furtive smirk in the hunchback’s face. He stepped briskly to the
+operating cot and shook the fellow’s arm.
+
+“I’m not so sure about that,” he remarked. “You have been up to some
+kind of deviltry, my man. Now——”
+
+The sentence ended in a gasp. In a twinkling the hunchback had wrenched
+his arm free of the doctor’s grasp. Cole was amazed at the swift play
+of his fingers. He could scarcely see what was happening, but a loop
+fell down over the physician’s head and was tightened around his throat
+with a quick jerk. He spluttered and choked, while the hunchback
+snickered gleefully.
+
+“I got yuh now!” declared the little man, drawing the loop still
+tighter. The doctor wriggled and squirmed, but the constriction at his
+throat weakened his efforts. The whole scene seemed unreal to Cole.
+It took him several moments to realize that Latham was being garroted
+by the man who had found refuge in his house after murdering Malcolm
+Reeves.
+
+He bounded forward, and a well-aimed blow sent the hunchback reeling
+back over the operating table. The garrote, made up of two shoe laces
+tied together, had bitten deep into the flesh around the doctor’s
+throat. His eyes bulged, and his gaping lips were bloodless. A hoarse
+rattle sounded in his throat, as he struggled for breath.
+
+In a short time the noose was undone, and the physician sank into a
+chair. While he sucked air into his lungs in great gulps he looked
+queerly at Cole. The hunchback lay sullenly silent on the table.
+
+“Your visit was very opportune this time,” murmured Latham, as soon as
+he began to breathe more easily. “Where did you come from?”
+
+Cole signified with a shrug that the matter was of no importance.
+“What’s gotten into this protégé of yours?” he asked with a glance at
+the hunchback. “Did he go crazy all of a sudden?”
+
+“Oh, no; he’s as sane this moment as he ever was or ever will be. I
+knew he would kill me if he got a chance, and so I did all I could to
+deprive him of the opportunity.”
+
+There was doubt and bewilderment in Cole’s gaze. “But why should he
+kill you? I thought——”
+
+“Yes, I think I know what you thought,” interrupted the doctor. “For
+a man of keen intellect you have a singular capacity for getting
+things twisted. I suppose, however, it isn’t to be wondered at under
+the circumstances. Wonder where the fellow got those shoe laces. I
+thought I had removed from his reach everything that might serve as an
+implement of murder.”
+
+Cole stepped to the trunk at which the hunchback had been squinting
+from time to time. He lifted the lid, and the first thing he saw was a
+pair of old shoes from which the laces had been removed.
+
+Latham looked at him in surprise. “That trunk was locked this morning,”
+he remarked.
+
+“The lock is a very simple one,” Cole observed. “Even a man with only
+one arm could pick it without much trouble. With a supply of matches
+handy, the removal of the electric bulb didn’t give him much of a
+handicap. You seem to lead a very exciting life, doctor.”
+
+The doctor smiled. He felt quite at ease again. He got up from the
+chair and strolled over to the table where the hunchback lay.
+
+“You are really very simple,” he declared. “Didn’t you know that
+murdering me wouldn’t help you out of your predicament? Why, you would
+have starved to death if you had carried out your attempt.”
+
+“Guess again.” The fellow leered insolently. “My pals woulda found me
+before long. To-night, maybe.”
+
+“What’s your grudge against the doctor?” inquired Cole. “Why did you
+try to kill him?”
+
+“Why don’t you ask him?” retorted the hunchback, wagging his head in
+the physician’s direction.
+
+“Our friend doesn’t seem very communicative,” observed Latham. “I don’t
+think he will attempt any more mischief to-night. Suppose we go down
+and sample one of my cigars?”
+
+Cole assented, but not until he had searched the hunchback and removed
+a handful of matches. He believed the doctor knew the motive behind the
+murderous attempt. There was a fog in his mind, for the scene he had
+just witnessed did not seem to harmonize with his previous observations.
+
+“You are a cool one, doctor,” he remarked when they were down in the
+consultation room and the physician had passed his box of cigars.
+
+“Life hardens one. I sometimes wish I hadn’t lost my emotional
+susceptibilities. They are the things that give color and tone to life.
+Life without thrills is a barren desert.”
+
+Cole suddenly recalled his original errand. He bent forward and looked
+the doctor full in the eyes. “There is one question I want to ask. You
+may not be able or willing to answer it. Where is Miss Brownell?”
+
+The question acted like an electric shock on the physician, upsetting
+his magnificent composure as nothing else could have done. A suspicion
+of pallor crept up beneath the black beard.
+
+“What about her?” he demanded sharply. “Has anything happened to her?”
+
+Cole smiled amusedly. “For a man who has lost his emotional
+susceptibilities you manage to work up quite a lot of feeling over a
+simple question. You know the lady I am referring to?”
+
+“Why—er—slightly.”
+
+Cole gave him a hard, searching glance. He felt the doctor had
+deliberately understated the truth. “Miss Brownell disappeared this
+evening,” he announced. “I came here in the hope of learning something
+of her whereabouts from you.”
+
+“Why from me?” Latham was laboring under a tension that he tried hard
+to suppress.
+
+“Several trails seem to point in your direction, doctor. Do you know
+what has become of Miss Brownell?”
+
+Latham gripped the arms of his chair. “I swear I haven’t the faintest
+idea,” he declared, looking Cole straight in the eyes.
+
+Cole believed him. There was something in the doctor’s tone and
+manner that carried conviction. He knew that for once the man was
+not shamming. His gaze cut deep into the physician’s bewildering
+personality, and he found not a trace of duplicity.
+
+“What is Miss Brownell to you?” he asked bluntly. “Not in love with
+her, are you, doctor?”
+
+The bearded lips parted in a faint smile. “I admire her immensely.
+Have known her for a long time. Was a friend of her father’s. A very
+charming young person indeed. But at my age one hesitates before he
+permits himself to fall in love. Besides, Miss Brownell is not likely
+to entertain any romantic notions in regard to me.”
+
+Cole nodded thoughtfully. Despite the doctor’s light tone and airy
+gestures, the real Dickson Latham stood revealed before him.
+
+“I understand, doctor,” he said meaningly. “I see how it is with you.
+As for Miss Brownell, she left a certain place, about an hour and a
+half ago, in pursuit of a colleague of yours, Doctor Ballinger.”
+
+A queer little mutter slipped from Latham’s lips. He clenched his hands
+convulsively; his face underwent a startling transformation; a mingling
+of hate and fear showed in his dark, flashing eyes.
+
+“That hound!” he mumbled under his breath, evidently not intending Cole
+to hear. With an inward wrench he steadied himself; in the next moment
+he seemed cool and composed. “In that case we must endeavor to find
+her,” he added aloud.
+
+“More easily said than done, doctor. Have you any idea where Ballinger
+might have taken her; in the event that she should have fallen into his
+hands?”
+
+“There is one place he would naturally take her to, but I don’t know
+the geographical location of it.”
+
+“In plain words, the headquarters of a certain gang of alchemists and
+cutthroats?”
+
+Latham nodded.
+
+“You are mixed up with this gang, aren’t you, doctor?”
+
+“I was.”
+
+“And you performed an operation on Malcolm Reeves?” Cole watched him
+closely to observe the effect of his question.
+
+“That is true,” said Latham in a queer tone. He smiled a sad, whimsical
+smile. “But you must have observed that truth sometimes covers a
+multitude of lies.”
+
+Cole pondered this cryptical statement. “One more question. Why did the
+hunchback try to kill you?”
+
+“Some men are willing to do anything for money. But this line of talk
+isn’t leading us anywhere. The thing of prime importance is to find
+Miss Brownell. From what little I know of the gang, to which you
+referred, I should say her life isn’t worth a plugged nickel if she has
+fallen into their hands.”
+
+He spoke evenly, but Cole sensed an ache behind the words. “Do you
+know the leader of the organization?” was his next question.
+
+“He was never referred to by name in my presence, and I never came in
+contact with him. In my dealings with the members I never got higher
+than Professor Carmody.”
+
+Again, despite the contradictions and discrepancies that hemmed in the
+doctor’s statements, Cole was disposed to believe him. “There is no
+cause for alarm just at present,” he declared. “We don’t know that Miss
+Brownell is in trouble. She is a capable young woman and——”
+
+“Ah, but you don’t know Ballinger,” interrupted Latham.
+
+Cole reached for the telephone and called the number of The Unknown
+Seven. After a brief delay he was connected with Carlin.
+
+“Where are you?” demanded the lawyer excitedly. “Been trying to get
+hold of you everywhere.”
+
+“What has happened?” asked Cole evenly, though the lawyer’s agitation
+was contagious.
+
+“Happened!” echoed Carlin. “Received an anonymous telephone message a
+while ago warning us that, unless we keep hands off, Miss Brownell will
+be dead inside twenty-four hours!”
+
+
+
+
+ CHAPTER XX
+
+ THE VENEER OF INTELLIGENCE
+
+
+The doctor’s face betrayed his anxiety, as Cole repeated what he had
+just heard over the telephone.
+
+“That settles it,” muttered the physician. “We must find Miss Brownell
+at once.”
+
+Cole nodded. For several minutes he had been watching the physician
+closely. It was as if a veil had been removed from one phase of
+Latham’s many-sided character. Cole looked through the contradictions
+of his personality, and he knew that on one point, at least, the doctor
+was sincere. That was in his attitude toward Miss Brownell.
+
+“There’s no hurry,” he said calmly. “Nothing is going to happen to her
+for twenty-four hours.”
+
+“But why delay?”
+
+“Because we can do nothing else. Another reason is that I need sleep.
+The third reason is Toots.”
+
+“Toots?” Latham frowned. “Who is Toots?”
+
+“The most distracted cat in the State of New York at the present
+moment. My rooms were invaded by prowlers this afternoon, everything
+thrown helter-skelter, and Toots just can’t bear fuss of any kind.
+She is a very temperamental cat, doctor. You will hear from me in the
+morning.”
+
+He left the scowling physician and walked toward the door. There he
+stopped and looked back. “Don’t worry,” he said. “We will see Miss
+Brownell out of this. There’s something of a plan buzzing around in my
+mind. So long, doctor.”
+
+Cole walked out. Despite his cheerful tone he was not altogether free
+from worry. The situation, as far as Miss Brownell was concerned,
+looked critical enough. With the fate of Reeves and McKendrick in mind,
+Cole knew the gang would not stop short of murder, if it suited their
+plans. The hope he had tried to instill in Doctor Latham was based on
+the advantages which he held over the other side. So far Ballinger
+did not know that he was being suspected, and this was an important
+point in Cole’s favor. A man who thinks himself safe is apt to make
+blunders and become incautious. Another advantage lay in the fact that
+the conspirators knew nothing of the deductions Cole had made from
+Carmody’s visit to the offices of the Bureau of Civic Research, or of
+his suspicions in regard to the big safe standing there.
+
+Cole went home, noticed with approval that Mrs. Armstrong had tidied
+up his rooms, and that Toots was sleeping tranquilly on her favorite
+cushion. In a few minutes Cole himself was sound asleep. Five hours he
+slept, and then he awoke clear-eyed and vigorous. After feeding Toots
+and getting his own breakfast, he went to the offices of The Unknown
+Seven. On his desk he found a note from Carlin announcing that the
+lawyer had, in accordance with Cole’s instructions, detailed one of the
+operatives to watch room 2512 and report at once if the safe should be
+taken out.
+
+Cole crumpled the note in his fist. It was yet early, and only a few
+members of the staff were on duty. He went to the end of the hall and
+glanced into the room where the body of McKendrick lay. What to do with
+it was a delicate problem in view of the fact that the operations of
+The Unknown Seven were being conducted secretly. Perhaps the best way,
+was Cole’s reflection, would be to encase it in a plain box and ship
+it anonymously to the morgue. Later, in some indirect way, he would
+endeavor to see that the hunchback was duly punished.
+
+He locked the door of the little room and went back to his office.
+He had been there only a few minutes when Doctor Ballinger, after a
+discreet knock, stepped in.
+
+“You are early, doctor,” remarked Cole genially.
+
+Ballinger sat down and crossed his long legs. “I’ve been looking for
+Miss Brownell,” he explained. “Seen anything of her?”
+
+“No,” said Cole casually, knowing that the doctor was watching him
+keenly. “A bit too early for her, I guess. No doubt she will be
+strolling in soon.”
+
+“Making any progress?”
+
+“Rome wasn’t built in one day,” said Cole evasively, knowing that the
+question was a subtle feeler. “I’m just taking hold of the job, you
+know.”
+
+“Still think there’s a traitor among us?”
+
+“I not only think it, but I am sure of it,” declared Cole testily, as
+if reproaching himself for his failure to expose the renegade. He was
+on the point of saying more, but just then the telephone rang. It was
+Fessenden, the operative who had been detailed to watch room 2512.
+
+“They’re just taking it out, sir,” reported Fessenden, cautiously
+hiding the gist of his statement behind the neutral pronoun.
+
+“Well, stay on the job and report developments to me,” said Cole in
+tones that seemed to indicate that the matter was of no particular
+importance. “You see,” he went on, turning to the doctor, as he hung up
+the receiver, “I spilled the beans at dinner. The traitor has had his
+warning, and from now on he will be a hard man to catch.”
+
+The doctor agreed with him. They discussed the matter from various
+angles and finally the telephone rang again. Fessenden reported that
+“it” had been loaded onto a truck.
+
+“Stay with it,” said Cole laconically. “Telephone me when you can.”
+He was aware of a questioning gleam in the doctor’s eyes, as he hung
+up, but he pretended to have noticed nothing. “Fessenden thinks he has
+come across a clew,” he added for Ballinger’s benefit. “Don’t think it
+amounts to anything, but it’s just as well to run it down.”
+
+“What sort of clew?”
+
+“It seems to have something to do with the murder of Reeves,” said Cole
+indifferently. “Not more than one clew out of twenty ever pans out, and
+I haven’t much hope for this one.”
+
+The doctor seemed to have been deceived by his tone. After a few more
+remarks he walked out. In spite of what he had told Carlin the night
+before, he had been far from certain that the safe would be taken out;
+at any rate he had not expected it would be done before another night.
+Fessenden’s report had started a long train of thoughts in his mind.
+
+Shortly before noon the lawyer walked in.
+
+“I’ve just made some inquiries about the Bureau of Civic Research,”
+he reported, after he had been told that there was no news of Miss
+Brownell. “There isn’t the slightest doubt about its genuineness.
+Some of the biggest men in town belong to it. It’s a sort of reform
+organization; interested in political uplift and that kind of thing.
+They’ve occupied the two offices down below ever since the building
+opened.”
+
+“That’s interesting,” said Cole, looking as if his trend of thought had
+taken a sharp quirk. “By the way, the safe was taken out of room 2512 a
+little while ago.”
+
+“Anything startling in that?”
+
+“Well, it’s just possible that, if we can follow the safe to its
+destination, we shall find Miss Brownell.”
+
+“How do you make that out? What has the safe to do with Miss Brownell?”
+
+“My reasoning is based on the assumption that certain parties are as
+anxious to hide the one as the other. If that is so then it is only
+natural to suppose that they will hide both in one place. That safe,
+Carlin, represents our only hope of getting Miss Brownell out of
+danger.”
+
+The lawyer scratched his head thoughtfully. “I would advise you to move
+cautiously. Those blackguards would kill her without the slightest
+hesitancy if——”
+
+“Oh, I’ll be careful,” promised Cole. “All the same we must move
+quickly. I think your hunch yesterday was right, Carlin. The gang is
+getting ready to cash in their chips. They are holding the threat of
+death over Miss Brownell in the hope of influencing us through her and
+making us let them alone till after the clean-up. The miserable cowards
+are hiding behind a woman. The idea makes me mad clean through.”
+
+“You look it,” observed Carlin. Shortly afterward he withdrew, and
+a little while later Fessenden telephoned that the safe had been
+transferred to a private yacht, moored at the foot of West One Hundred
+and Thirtieth Street. Fessenden did not know to whom the craft
+belonged. He added that it did not look as though the boat would start
+for a while, for the crew were on shore leave. Cole instructed him to
+report at once if it should appear that the yacht was about to sail.
+
+“They’ll probably wait till after dark,” he told himself after
+Fessenden had finished. “Rather bold of them to put it aboard a yacht
+in broad daylight. Really no reason why they shouldn’t, though,” was
+his second thought. “As far as they know, nobody suspects anything. It
+would look as if the safe was being shipped to a summer home somewhere
+along the shore. Many people keep jewelry and other valuables in
+such places, and a safe comes in handy. And to transport it by water
+on a private yacht is less risky than intrusting it to the express
+companies. There’ll be a merry little chase to-night.”
+
+Cole looked as if a whimsical idea had occurred to him. He called up
+Latham and inquired if the doctor owned a motor boat. The physician
+replied that he did; it was a small affair, he explained, but a demon
+for speed. Cole promised that he would learn something interesting if
+he would have the boat ready within an hour, at a certain point along
+the river. Latham’s imagination seemed to cover the gaps in Cole’s
+statement, for he promptly agreed to do as suggested.
+
+After giving several orders Cole left the office. His rendezvous with
+Latham was a short distance below the point where the larger craft was
+moored. Before boarding the doctor’s boat Cole went cautiously forward
+and sought out Fessenden.
+
+“The wind is slack, and the engine seems to be out of order,” explained
+the operative. “I believe somebody is tinkering with it.”
+
+“Have you learned who owns the yacht?”
+
+“I’ve made several inquiries, but nobody seems to know. She is
+brand-new, as you can see, and this appears to be the first time she
+has been anchored here.”
+
+Cole cast a glance at the queenly craft, its fresh coat of paint
+gleaming in the pale autumnal sunlight. After telling Fessenden that he
+could take the rest of the afternoon off he went back to Doctor Latham.
+The physician, looking fresh and crisp in blue coat and creamy flannel
+trousers, sat at the tiller.
+
+“When do we start?” he inquired anxiously.
+
+“We’re waiting for the other party to make the first move,” explained
+Cole, pointing out the larger boat, easily distinguishable among the
+craft of various types that littered the surface of the river.
+
+“Any news of Miss Brownell?”
+
+“Not a word, doctor. Are you in the mood for a little excitement?”
+
+The physician said nothing, but his smile and the squaring of his
+shoulders spoke more loudly than words. Cole glanced out over the
+horizon. A frieze of clouds was creeping up in the south, and a rising
+wind rippled the water.
+
+“I suppose you are armed?” he asked after a while.
+
+The doctor slapped his hip pocket significantly. “Are we likely to have
+a scrap?” he inquired in a tone hinting that the prospect appealed to
+him hugely.
+
+“Quite likely! The rats are scenting danger and crawling into their
+hole. We may have to tackle a whole nest of them.”
+
+The afternoon waned and still they waited. Darkness fell, and a
+spanking breeze blew up. At Cole’s suggestion the doctor moved the
+motor boat a little closer to the larger craft.
+
+“They are hoisting the sail,” observed Latham, as he brought the boat
+to a stop at a point from which they could watch the yacht without
+danger of being seen by its crew. Here and there the black ribbon
+of water was broken by twinkling lights. An excursion steamer swept
+majestically up the Hudson, with a tail of foaming silver in its wake.
+
+Presently the yacht moved. The two men in the motor boat waited a while
+to give it headway. Then the doctor flipped the wheel, and, with a
+gleeful phut-phut, the little boat darted forward. Like an animated
+thing it skipped giddily across the water, darting in and out among
+larger vessels. After a little the sprinkling of boats thinned out,
+and they hugged the shore closely, in order to avoid being seen by the
+yacht’s crew.
+
+“Think you can keep her in sight, doctor?” asked Cole, noticing with
+concern that the larger boat was gaining speed.
+
+“Easily,” said the doctor confidently, “unless the motor should start
+missing, and there’s little danger of that.”
+
+They were silent for a time. Cole, sitting close by, watched the intent
+look on the doctor’s face as he guided the boat along the curving river
+bank. The shore line grew more rugged; here and there earth and sky
+melted into a blur. Now and then the lights of a town threw a yellow
+sheen over the murky water. At intervals the yacht disappeared from
+view behind a jutting tongue of land, but it was never out of sight for
+long.
+
+“Doctor,” said Cole abruptly, “I don’t quite know what to make of you,
+but we seem to have one interest in common. Both of us are concerned
+over Miss Brownell. I am partly responsible for whatever happens to
+her, while you—— But I think you told me that your emotional self is
+dead.”
+
+A queer little chuckle drifted out on the breeze. There was a note of
+grim despair in it.
+
+“Anyhow,” Cole went on, “there is a bond of interest between you and
+me for the present. Seems we ought to understand each other a little
+better. The other night, when I trailed the hunchback to your house and
+later found him asleep on the operating table, your conduct was as
+mysterious as the deuce. What had happened?”
+
+The doctor, one hand on the tiller, gazed rigidly out over the black
+water to where the gray blur of a sail was visible against the darkness.
+
+“The thing which we call human intelligence is only a thin veneer,” he
+remarked in whimsical tones. “Sometimes only a slight thrust is needed
+to break through it. It is very amusing to watch the antics that a
+supposedly sane being will perform when a crisis of some sort comes
+along and gives him a jolt. My own part in this affair is an example
+of what happens when the veneer of intelligence cracks. You would not
+believe me if I were to tell you, so what is the use?”
+
+“You might try,” suggested Cole. The doctor had been a changed man
+since he learned that Miss Brownell was in danger. Before that he had
+been all subterfuge, evasions, and bewildering subtleties. Now Cole
+felt that he was face to face with the man’s real self.
+
+“The hunchback came to my house that night to dispatch me to a better
+world,” Latham said.
+
+“He had just performed a similar service for Malcolm Reeves,” Cole
+observed.
+
+“He had orders to get me, too. The gang feared both of us, and they had
+come to a pass where they couldn’t afford to stand on ceremony. Well,
+that night I heard some one getting in the basement way. That’s the
+advantage of being a light sleeper. I collared the fellow as he came up
+the stairs. Not knowing what to do with him I gave him a hypodermic to
+keep him quiet. Then you came and complicated the situation.”
+
+“If the hunchback came to your house to murder you,” said Cole
+doubtfully, “why didn’t you turn him over to the police?”
+
+The doctor chuckled softly. “That shows how incongruously we sometimes
+act, strutting around like hens with their heads chopped off. Your own
+conduct was very peculiar that night. I was wondering why, instead of
+handcuffing the culprit to my operating table, you didn’t telephone for
+the police wagon.”
+
+“I had a reason.”
+
+“And so did I.” The doctor chuckled again. “At least I thought I had
+a sound reason for my conduct. As a matter of fact my reason was at a
+standstill; no doubt yours was likewise. At any rate I didn’t dare hand
+the fellow over to the police. Certain things had happened that made it
+undesirable for me to communicate with the authorities.”
+
+“The operation on Reeves?” Cole suggested.
+
+Again a queer little laugh drifted out on the wind. Cole suddenly
+sat erect, gazing hard at the shadowy figure beside him. A shaft
+of intuition had suddenly pierced the fog of contradictions and
+incongruities in his mind.
+
+“There were two operations, weren’t there?” he asked.
+
+“That’s a very shrewd deduction,” declared the doctor, raising his
+voice above the roar of the wind. “There were two. I performed one
+of them. I strongly suspect that Ballinger performed the other. The
+interesting point about them is that there is an official record of the
+first, but none of the second.”
+
+For a moment Cole peered sharply ahead. The yacht was momentarily out
+of sight, but he caught a glimpse of it again, as they rounded a curve
+in the river bank.
+
+“Go on,” he said. “You were involved with this golden coterie, weren’t
+you?”
+
+“For a time. I thought they were engaged in strictly scientific and
+legitimate pursuits. I had known Carmody for some time, as a quiet and
+scholarly man. It was through him I became connected with the group.
+For a time all went well. My specialized training helped them solve two
+or three minor technical problems that came up in connection with their
+experiments.”
+
+“Then one evening Carmody telephoned me that an accident had occurred
+at his house on Bleecker Street. He asked me to come over at once.
+When I arrived he told me that Malcolm Reeves, who was visiting him
+that evening, had stumbled and fallen down the stairs. My examination
+revealed a compound fracture and convinced me that the pressure of the
+bones against the brain made an immediate operation necessary.”
+
+“I had Reeves removed to the nearest hospital. It happened to be one of
+the smaller private ones. I was assisted by a nurse. She was a little
+nervous, and I could see that she was new at the game, but at first I
+thought nothing of it, not until I discovered that there was something
+wrong with the anæsthetic. She had blundered in administering it. I
+shudder whenever I think of the result. Perhaps you can realize
+something of what it means to have a patient awake in the midst of an
+operation.”
+
+“Did Reeves see you?” asked Cole suddenly.
+
+The tiller wabbled for a moment in Latham’s hand. “He not only saw me,
+but he recognized me. I shall never forget the expression on his face.
+It was horrible! Well, luckily there were no serious consequences.
+After a while Reeves was brought under the anæsthetic again, and the
+operation was successfully finished. In due time he was taken to his
+home. To this day I don’t know whether Carmody told me the truth and
+the injury was accidental, or whether some one deliberately inflicted
+it.”
+
+“Couldn’t you tell from the nature of the wound?”
+
+“Not with any degree of positiveness. I suspect some one tried to
+murder him that night, but failed. Perhaps the assassin lost his nerve.
+Carmody didn’t dare to have Reeves die on his hands, and so he sent for
+me. I do know that Reeves had been troublesome toward the last, and
+that the other members of the gang were afraid of him. They had ample
+reason for wishing him out of the way, or at least rendered harmless.”
+
+“And so they performed a second operation that destroyed his memory?”
+guessed Cole.
+
+“Presumably, but that’s only a surmise on my part. Reeves recuperated
+very rapidly after the first operation. One evening, shortly after he
+became able to move about, he started out on a mysterious errand. He
+never returned, and the police found no trace of him. About the same
+time I began to grow suspicious in regard to the activities of the
+gang. I had no tangible proof, but it was my strong impression that
+their aims were not strictly legitimate.”
+
+“Isn’t anybody entitled to make all the gold he wants to, if he’s lucky
+enough to know how?”
+
+“That’s just the point. Carmody assured me he had discovered a process
+whereby real gold could be produced synthetically. It would not only
+look like gold, he told me, but it would assay up to the required
+standard when turned over to the government mints. Carmody put it so
+convincingly that at the time I believed him, especially when he showed
+me samples. Later I began to have grave suspicions. Certain things
+led me to doubt that the gang had sufficient faith in its products to
+turn it over to the government in the form of bullion. In short, I had
+reason to believe that I was involved in a huge counterfeiting project.”
+
+“What!” exclaimed Cole. The doctor’s revelation went beyond what he had
+learned from The Unknown Seven.
+
+“To eliminate all risk the gang decided to take a short cut,” Latham
+went on. “Instead of taking the gold to Uncle Sam’s mint they set up
+a mint of their own. In a short time the country will be flooded with
+spurious gold coins that are practically indistinguishable from the
+real.”
+
+“And you have kept silent all this time?”
+
+“What did I tell you about the fragile quality of our veneer of
+intelligence? I went to Carmody’s house and told him of my suspicions.
+The old fox said nothing for a time, but merely smiled that freezing
+smile of his. Then he took me to a small room on the second floor.
+There sat Reeves, a gibbering maniac. Carmody bluntly accused me of
+having performed the operation that deprived him of his reason and
+smoothly suggested that it might be well for me to keep my suspicions
+to myself.”
+
+“Carmody went on talking, mentioning among other things that it was
+on record that I had performed an operation on Reeves’ skull. Call me
+a simpleton if you like, but the professor’s words sank in. I guessed
+that a second operation had been performed under cover of the original
+one, but I had no means of proving it. I could see nothing but ruin
+and disaster ahead. The only one who had witnessed my operation was
+the nurse, and I could expect no help from her. I argued and argued
+with myself, but, in the end, I decided to say nothing, at least for a
+time. Sooner or later I suppose I should have spoken, but just then I
+played the coward’s part. I was very neatly caught. In what was left of
+Reeves’ mind was a picture of myself, as he had seen me when he woke
+up in the midst of the operation. Occasionally, when the recollection
+came back to him, he would shriek my name. The second operation, on the
+other hand, had been performed under circumstances so deftly arranged
+that they had left no impression whatever. There, my friend, you have
+the whole story. Sounds like a travesty, eh? I shan’t feel at all hurt
+if you refuse to believe me.”
+
+Cole had no reason to doubt him. What Latham had told him coincided at
+various points of contact with what he had learned at the headquarters
+of The Unknown Seven. He could piece out the rest. Agents of The
+Unknown Seven had kidnaped Reeves from the Carmody residence and taken
+him to headquarters. There he had been placed under Doctor Ballinger’s
+care, and Ballinger had gone through with the pretense of trying to
+restore Reeves’ mental functions. Only one contradiction remained.
+Since Reeves was in the hands of a physician who was friendly to the
+gang and could be depended upon to destroy any symptoms of returning
+sanity in Reeves, why had it been thought necessary to kill him?
+Ballinger himself evidently shrank from such a coarse crime as murder.
+He must have had several chances to kill Reeves by safe and subtle
+means, and yet the hunchback had been commissioned to do the crime. Why
+had Reeves been killed?
+
+For a while the answer to that question eluded Cole. Then he recalled
+something Carlin had told him. After Reeves had been under Ballinger’s
+care for a time, without showing any signs of improvement, it had been
+suggested that he should be removed to a hospital and a consulting
+physician called in. Evidently Ballinger had seen a danger to himself
+in that suggestion, and so the murder had been decided upon.
+
+“I have no reason to doubt you,” Cole said. “I don’t know but what I
+would have acted pretty much the same if I had been in your place. I
+think, though, that you have done a lot of needless worrying. Ballinger
+is not at all confident of being able to fasten the second operation on
+you.”
+
+“How is that?” asked Latham quickly.
+
+“I can’t tell you, but I have every reason to believe that Ballinger
+is afraid of what an autopsy on the body might show. Not being a
+scientific man I can’t grasp the details. All I know is that Ballinger
+is so anxious to prevent an autopsy that he is having the body spirited
+away.”
+
+Latham’s hand left the tiller, and the boat lurched dangerously. In a
+moment he had regained control of it.
+
+“Unless I am a very poor guesser,” Cole went on, “the body is on the
+yacht ahead of us. They are taking it to a place where it can be safely
+destroyed. It’s hard to do such things in the city.”
+
+Latham stared at him speechlessly through the dusk. The wind had
+increased, and the waves were swishing and churning against the bow of
+the little craft.
+
+“It may be Ballinger is suffering from an uneasy conscience,” the
+doctor murmured. “That’s one of the things that happen when the veneer
+of intelligence cracks. Conscience makes a man do queer things.
+However, if your guess is right——”
+
+He stopped short, at the same time peering sharply ahead. Suddenly his
+hand went out, and the chugging of the motor ceased.
+
+“The chase is over,” he said.
+
+Cole followed his glance. The yacht, with sails lowered, was turning
+into a small inlet.
+
+“And here is where the excitement begins,” he declared.
+
+
+
+
+ CHAPTER XXI
+
+ THE FACE AT THE WINDOW
+
+
+While Doctor Latham fastened the boat, Cole’s eyes swept the black
+masses of wooded hills that slanted upward at a sharp angle from the
+river bank. At the apex of the tallest peak a light gleamed, but
+otherwise there was no sign of human habitation on this side of the
+river. The lights of a town twinkled across the foaming welter of
+waves, and they helped Cole to fix their location. They were in one
+of the wildest and most rugged sections of Dutchess County. The peak,
+on which the solitary light shone, had once been a popular pleasure
+resort, and in the old days a cable railway had carried week-end
+excursionists to the top. Of late, what with the dry era and the
+public’s fickle fancy, the place had lost its popularity, and the
+buildings on the peak were falling into decay. The ruggedly romantic
+setting seemed an ideal one for the kind of adventure Cole anticipated.
+
+With the doctor at his heels, he moved cautiously toward the point
+where the yacht had anchored a short distance ahead. Of a sudden they
+stopped. The crack of a pistol rose sharply above the whine of the wind.
+
+“Only a signal, I think,” said Cole, after waiting tensely for a few
+moments.
+
+They advanced a little farther, then stopped on a slight elevation from
+which they had an unobstructed view of the yacht. In the lights from
+the craft they saw a number of men going ashore, and several of them
+were carrying a bulky object. Their faces were not recognizable at that
+distance, but Cole thought there were about a dozen in all.
+
+“We may have quite a lively tussle,” he observed in an undertone. “I
+could have brought a few helpers along, but safety doesn’t always lie
+in numbers.”
+
+“I like this better,” said Latham. “If there were more of us there
+might not be enough thrills to go around. Where are we?”
+
+“That place, up there in the clouds, where you see the light, is called
+Dutchess Point. I believe there is a car coming down. That’s probably
+what the pistol shot meant.”
+
+A light was treading its way in a zigzagging course down the side of
+the hill. Soon were heard the chugging of motors and the metallic snarl
+of brakes. The two men waited until the car reached the group that had
+come off the yacht. As soon as the loaded vehicle started to retread
+its path up the hill they followed. It proved a hard climb, and they
+reached the top a full half hour behind the car.
+
+The apex was composed mostly of huge flat rock, with here and there a
+few scrawny trees. There were half a dozen buildings scattered about,
+and in the largest one several lights had appeared by the time the two
+climbers reached the top. They stood in a dark spot behind a little
+cluster of starving hemlocks. No one was in sight, but the sound of
+voices drifted out to them through the open windows of the large
+building.
+
+“Hear that noise?” whispered Latham. “What do you suppose it is?”
+
+Cole listened. A gentle, rhythmic whirring was heard. He looked down at
+his feet, for it seemed to come from underground.
+
+“Machinery,” he said, and suddenly he remembered the words spoken by
+Malcolm Reeves in his insane glee: “Yellow—pretty yellow.” The whirring
+noise that he heard, as he stood there under the hemlocks, brought them
+back to his mind.
+
+“Look!” said Latham suddenly.
+
+Cole, following his pointing finger, glanced upward. The large
+building, he now noticed, was equipped with a high tower, and near its
+top a light had appeared in the last few moments. At the lighted window
+a face was dimly discernible. Cole strained his eyes at the point of
+illumination, and suddenly he gripped his companion’s arm.
+
+“It’s a woman, Latham!”
+
+The doctor gasped. “It must be Miss Brownell, then!”
+
+The two men continued staring upward. Their imaginations touched up the
+dim and remote picture which they saw with their eyes. The face was
+very white, thought Cole, and the eyes held a look of terror. She was
+looking downward; their glances met somewhere in mid-air, and yet she
+appeared not to see the two watchers below.
+
+“What shall we do?” asked Latham.
+
+“You stay here,” said Cole. “I’m going to look around a bit.”
+
+He slipped away among the trees, avoiding the open space in front
+of the building. The tower was in the rear, overlooking the steep
+incline, and he moved in that direction. He looked up a sheer wall
+to where the light shone. To climb up there was out of the question,
+for the blank wall offered no hold for either hands or feet. He moved
+cautiously toward the front entrance. For a moment he listened outside
+the sagging door, then boldly pushed it open and entered.
+
+He was in a dark corridor. Under one of the doors at the side was a
+thin wedge of light. A number of voices issued from it; evidently a
+conference of some kind was in progress. Knowing that the stairway
+leading to the tower must be in that direction, Cole tiptoed farther
+down the hall. A bold and reckless move, he had learned from
+experience, was often more effective than a thought-out plan. Before he
+could do anything else Miss Brownell must be rescued. His hands were
+tied, as long as she was held as a hostage by the gang. Once she was
+out of harm’s way he could proceed against them as ruthlessly as he
+pleased.
+
+He came to the end of the hall, and there he brought up against another
+door. He opened it, almost sure that it must lead to the stairs, but
+instead he found himself in a large, square room. A small electric
+bulb glowed in the ceiling, and in its light he caught a glimpse of a
+forbidding figure guarding a door at the farther side. The sentinel was
+thickset and broad-shouldered. His bushy brows seemed top-heavy for his
+very small eyes which glared out at Cole in a startled way.
+
+“Stop right where you are!” he commanded, at the same instant reaching
+for his hip pocket. As his fingers closed around the handle of an
+automatic, Cole lunged forward. His fist landed with explosive force in
+the man’s face, and he fell to the ground without a sound.
+
+“Sorry, old top, but it had to be done,” Cole told the insensible man,
+as he opened the door which the fellow had been guarding. Before him
+was a winding stairway that seemed to extend upward interminably. Very
+quickly Cole lifted the man through the door and stretched him out
+along the steps, then drew the door to.
+
+He hurried up the stairs. The long ascent would have exhausted a weaker
+man, but Cole’s lungs and muscles were in the pink of condition. At
+length, panting a little, he reached the top. Before him was a door. He
+rapped, and footfalls crossed the floor within.
+
+“Who’s there?” demanded a voice which he recognized as Miss Brownell’s.
+It sounded a bit lofty, pathetically so, he thought.
+
+“Cole,” he replied.
+
+“Oh!” The exclamation was more a sigh of relief. “But I can’t let you
+in. The door is locked, and I have no key.”
+
+“I might have known it,” muttered Cole. The space between the door
+and the wall of the tower was very narrow. Bracing his back against
+the wall he placed his feet on the door and shoved steadily. It was
+of stout material, but at length it gave with an abruptness that
+precipitated him to the floor. Quickly he picked himself up.
+
+The girl rushed toward him. There was an excited flush which
+surmounted the white of her face. “I am so glad——” she began.
+
+“You were foolish,” Cole sternly interrupted. “You shouldn’t have
+started after Ballinger alone. That’s no job for a woman. What
+happened?”
+
+“Ballinger was too clever for me,” she confessed. “The moment I thought
+I had him I was shoved into a car, blindfolded, and—— Well, that’s
+about all I know. When I opened my eyes the next morning I found myself
+here.”
+
+“How have they treated you?”
+
+“Oh, very well, suspiciously well. I have been told that prisoners who
+are doomed to die always get the best of everything. Mr. Cole, you have
+thrown a full-sized scare into the gang. I heard a couple of the men
+talking outside my door this morning. I suppose they felt sure I would
+never have a chance to repeat what I heard. They said——”
+
+“Not so loud!” admonished Cole.
+
+“I gathered from what they said,” she went on in a whisper, “that the
+leaders of the gang are badly frightened. They seem to think you are
+hot on their trail.”
+
+“They’re mistaken,” declared Cole modestly. “I’ve barely got started as
+yet.”
+
+“Well, all the same they are very much worried. Their plan, as one of
+the men put it, is to make a swift clean-up and a quick get-away. Some
+one, whom they called ‘the big chief,’ was to come out here to-night.”
+
+“About a dozen men arrived a little while ago,” Cole informed her. “No
+doubt the chief was among them. Do you know who he is?”
+
+“No. He wasn’t referred to by name in the conversation which I
+overheard. I am sure, though, that Doctor Latham isn’t the man. In fact
+I never really thought so. More of my woman’s intuition, I suppose.”
+
+“What else did the men say?” he asked in a whisper.
+
+“They said there is about half a billion dollars’ worth of gold ready
+to be minted. I didn’t quite understand what they meant by that. There
+is a complete set of machinery hidden somewhere about the place, and it
+is running at full capacity.”
+
+“I should think the comings and goings of the gang would excite the
+curiosity of the townspeople across the river.”
+
+“Oh, they’ve managed that part very cleverly by circulating a report
+to the effect that the buildings are being renovated and that Dutchess
+Point is to be reopened as a pleasure resort next spring. In fact, they
+have put a crew of carpenters, roadmakers and gardeners to work on the
+place. Just for a blind, of course. It seems they haven’t neglected a
+single precaution. Yet they seem to be worried over something.”
+
+“Excellent! When your enemy is worried, you have an advantage over him.
+What seems to be the trouble?”
+
+“I couldn’t quite make out. All I heard was a few scattered remarks. It
+appears they are having some difficulty with the gold-making process.
+There seems to be a minor flaw in the product, due to the absence of
+something which they refer as the seventh ingredient. I haven’t the
+least idea what it is, but it seems to be related to the experimental
+work Doctor Latham conducted before he severed his connection with the
+gang. They appear to think that he could solve their difficulty if he
+was so inclined.”
+
+“By supplying the formula for the seventh ingredient?”
+
+“Something like that. Anyway, that was the impression I received.
+Evidently the missing ingredient isn’t of very great importance, but
+they want to make the product as perfect as possible.”
+
+“For the sake of safety in minting and circulating it, I suppose,”
+said Cole thoughtfully. “Apparently Latham left them at an inopportune
+time from their point of view. Doubtless they would exert any manner
+of pressure on him in order to make him divulge the secret of this
+so-called seventh ingredient.”
+
+“I doubt if they would succeed.”
+
+“So do I,” said Cole, looking curiously at the girl. “Latham is a
+fighter clean through, and he is a match for them. By the way, he came
+out with me this evening.”
+
+She caught her breath and fixed her wide, troubled eyes on his face.
+
+“Doctor Latham here?” she murmured. “Did he volunteer to come with you?”
+
+“I invited him to come, and he jumped at the invitation. I foresaw that
+he would prove useful, and he was doubly anxious to come when I hinted
+that our expedition to-night might reveal your whereabouts. Your
+disappearance came as a great shock to him.”
+
+“Then you no longer think he is implicated with these scoundrels?”
+
+“No, I don’t. He was with them until he saw that their aims were
+crooked, and then he got out as best he could. Latham has acted
+foolishly, but that’s all. The scientific side of these experiments
+appealed to the scholar in him. I don’t think he was ever moved by
+greed. No, Latham wasn’t to be blamed. Whenever a man is in love he is
+apt to make a fool of himself.”
+
+She lowered her eyes. “Doctor Latham is a good man,” she said tensely.
+“I wish I could——” A gentle sigh escaped her.
+
+“I understand,” murmured Cole. “Life is a bit of a tangle, isn’t it?
+Even the logical mind of a scholar isn’t able to steer clear of the
+meshes when a charming woman is involved. One never knows——”
+
+He paused, threw a quick glance at the door, then looked at Miss
+Brownell, noting the tensity that had suddenly crept into her face.
+In an instant his automatic was in his hand, and he tiptoed softly to
+the door. Holding it open a crack, he heard unmistakably the sounds of
+footsteps coming up the stairs.
+
+“Stand back!” he ordered curtly. “Some one’s coming!”
+
+But the girl, smiling faintly, signified with a shrug that she intended
+to remain where she was.
+
+
+
+
+ CHAPTER XXII
+
+ A DUEL OF WITS
+
+
+Cole opened the door a trifle wider. The footfalls, furtive and
+hesitant, sounded as if several men were coming up the protesting
+stairs. He fancied there were many others below who were ready to jump
+into the fight if he should be successful in disposing of the ones now
+approaching. His mind worked with lightning speed as he turned away
+from the door.
+
+The room, hexagonal in shape, with a tall window at each angle, was
+lighted from a tarnished brass fixture at one side. While watching
+the light from the outside, Cole had noticed that from the windows to
+the ground was a sheer drop of one hundred and fifty feet, so escape
+in that direction was impossible. The walls, covered with once gaudy
+paper that was now faded and torn, seemed to offer no loophole. The
+unswept floor was cluttered with pieces of dilapidated furniture of
+a kind which suggested that the room had once served as a rendezvous
+for gamblers. The single door was the only exit, and flight in that
+direction was cut off by the men now creeping up the stairs. As nearly
+as Cole could determine from the sounds, they were as yet only halfway
+up. For an instant his thoughts flew to Doctor Latham, and he wondered
+if the physician was still waiting for him outside.
+
+He stepped quickly toward the girl. “Talk,” he whispered, “talk about
+anything.”
+
+She took her cue with a comprehending nod, and Cole hastened back to
+the door.
+
+“But I don’t know, so how can I tell you?” she asked in a tone whose
+naturalness instantly won his approval. He was quick to follow up her
+lead.
+
+“You have no idea who the leader of these cutthroats is?” he asked in a
+slightly nettled tone.
+
+“None whatever.”
+
+He listened for a moment. The footsteps were coming gradually closer.
+When he spoke again, he threw his voice so that it sounded as if coming
+from the center of the room, a ventriloquial trick he had practiced
+when a boy and often found useful.
+
+“You have been here a good many hours,” he pointed out. “I thought you
+might have overheard something that gave you a clew.”
+
+“You forget that I have been locked up in this room all the time.”
+
+“That’s so,” Cole admitted, tightening his grip on his automatic. The
+footfalls on the stairs had ceased. Evidently the persons who were
+approaching had stopped to listen to the conversation. “You haven’t
+seen any one who looks as if he might be the boss of the outfit?”
+
+“No one,” she declared convincingly. “So far I have come in contact
+only with underlings. The man higher up, whoever he is, has remained in
+the background. Of course, I could make a guess.”
+
+“Let’s hear it.”
+
+“Doctor Latham.”
+
+Cole smiled. It was an excellent bit of strategy, and he was confident
+that the men below had heard. Her cleverly simulated suspicion in
+regard to the physician was well calculated to deceive them in regard
+to the extent and accuracy of her information.
+
+“You may be right,” he said thoughtfully just as the footsteps began to
+move upward again, and once more his voice sounded as if coming from
+the interior of the room. “I’ve had my eyes on the doctor myself. He is
+a sly bird, but I’m not sure that his cranium is the adequate size for
+a job of this kind. However he will bear watching. But we’re wasting
+time. The first thing to do is to get you safely out of this nest of
+crooks. I think the way is clear, but we must——”
+
+“You’re a little bit slow,” said a voice, and the door came open,
+admitting a stocky individual with a leveled automatic. He came
+straight forward, stopping bewilderedly as he saw only the girl, and
+in that instant Cole reached out behind him, seized him firmly by the
+neck and, swinging him backward with a powerful sweep, slammed his head
+against the wall. With a fragmentary cry the man went lurching to the
+floor, and in almost the same instant Cole whirled round and struck
+his companion a vigorous blow with the butt of his pistol. The fellow
+dropped like a dead-weight.
+
+“Two of them!” exclaimed Cole, feeling quite elated at the success of
+his ruse. “Where’s the third?”
+
+Miss Brownell, breathing rapidly, looked hard at the door. Cole glanced
+out, but there was neither sign nor sound of movement on the stairs.
+
+“I thought there were several of them,” he muttered. “Must have been
+mistaken. Sounds are deceptive, you know. This may come in handy.”
+
+He stooped, picked up the weapon dropped by his second adversary,
+and handed it to Miss Brownell. With an expert air she examined the
+mechanism, making sure it was loaded.
+
+“You worked the trick to the queen’s taste, Miss Brownell,” he declared
+approvingly. “It was a good piece of work.”
+
+“But you did it all.”
+
+“Far from it! I couldn’t have thrown them off their guard if you hadn’t
+helped. Do you know,” peering at her curiously, “I was afraid you would
+faint, or something like that.”
+
+She laughed. “You haven’t a very high opinion of our sex, Mr. Cole.”
+
+“It is rising every moment. We must get away before these rascals come
+to. Feel strong enough for a walk?”
+
+“Just try me! Your exhibition of fisticuffs was so stimulating that I
+am ready for anything.”
+
+“Then let’s start. Latham must be wondering what has become of me.”
+With a glance at his fallen foes, Cole started down the stairs, the
+girl following. He did not wish to alarm her by voicing his misgivings,
+but he was far from certain that they would reach the bottom without
+an interruption. Doubtless the others must be aware by this time that
+something was amiss. The burly sentinel he had knocked down at the foot
+of the stairs had probably either recovered consciousness or been found
+by his accomplices. In either event, their path was beset by perils.
+
+Pistol in one hand, Cole proceeded cautiously down the stairs. They
+were dark, and the constant winding made progress difficult. He had
+discovered that Miss Brownell was brave and resourceful, but he would
+breathe more easily when he had got her out of harm’s way.
+
+They reached another turn, and suddenly the girl stumbled and lurched
+violently against him.
+
+“Ouch!” she moaned, trying to repress an exclamation of pain. “My
+ankle! I think I twisted it.”
+
+Cole cursed softly as he gathered her in his arms. Her figure was
+writhing in the throes of physical distress.
+
+“As I told you once before,” she complained mockingly, trying to make
+light of the injury, “you are not at all gallant. Almost any other man
+would have welcomed the chance.”
+
+Cole muttered something under his breath. A dislocated ankle
+complicated a situation that was already critical enough, but the
+girl’s superb behavior stirred him to unwilling admiration. His fears
+were all for her, not for himself. He was almost at the foot of the
+stairs now. If he could only get her safely out of the building and
+place her in Doctor Latham’s care. If only——
+
+Abruptly he stopped before a door. With his burden in his arms he had
+reached the foot of the stairs. For a moment he stopped and listened,
+but all seemed quiet on the other side. An involuntary moan of pain
+told that Miss Brownell was suffering intensely. Balancing her on his
+shoulder he reached out a hand and pushed the door open.
+
+Instantly he felt a premonition that something was wrong. The sentry,
+whom he had left unconscious at the door before ascending to the tower,
+was no longer there. He started to draw back, but it was too late. A
+shadow leaped swiftly across the path of light in front of the open
+door. A hand clutching a bludgeon was raised to strike. Cole, with
+the girl on his shoulder, could not dodge the blow. It caught him
+squarely on the jaw, and the terrific impact sent him reeling against
+the stairs. The girl slipped away from him, and in his last conscious
+moment he tried to ease her fall.
+
+“I take it all back,” she whispered in his ear, her bantering tone
+edged with pain and anguish. “You—you _are_ gallant, Mr. Cole.”
+
+But Cole heard nothing.
+
+
+
+
+ CHAPTER XXIII
+
+ THE SEVENTH INGREDIENT
+
+
+When, some thirty or forty minutes later, Cole opened his eyes and
+fingered his swollen jaw, he found himself sprawling in a chair in
+a strange room. In front of him stood Doctor Latham, a humorously
+sympathetic look on his face.
+
+The room, with its faded tawdriness and crumbling decorations, looked
+as if it had once been a private dining room. The scratched woodwork
+and the liquid stains on the wall paper were reminiscent of hilarious
+times. Cole noticed that the two windows were shuttered on the outside.
+
+“How do you feel?” inquired the physician.
+
+“As if I was all jaw,” said Cole, opening his eyes a little wider and
+gazing stupidly at the doctor. It took him several minutes to recall
+that he was still in the big house on Dutchess Point. A rhythmic
+vibration that seemed to come from beneath the floor, accompanied by
+the remote humming of machinery, brought him back to the present.
+
+“Why are you here?” he demanded of the physician. “Didn’t I tell you to
+stay outside?”
+
+“So you did, and it was excellent advice, my friend. I wish now I had
+heeded it. But I grew impatient and proceeded to find out what had
+become of you. All I got for my pains was an ungentle tap in the region
+of the occipital bone.”
+
+With a serio-comic expression the doctor caressed the back of his
+head. His clothing was rumpled and looked as if he had been dragged
+over a dusty floor.
+
+Again Cole stroked his jaw. “Where is Miss Brownell?” he suddenly asked.
+
+Latham pointed across the room where, white-faced but smiling, the girl
+sat in a chair.
+
+“I’ve justified my existence at last,” he remarked. “I managed to
+straighten out Miss Brownell’s ankle. Didn’t have my kit with me, and I
+fear I dealt rather roughly with her. How about it, Miss Brownell?”
+
+“I hardly felt it,” she assured him. “For a big man, you are gentleness
+itself.”
+
+The physician looked long into her smiling face, and when he turned
+away there was a sad, wistful expression in his eyes. Miss Brownell
+caught a fleeting glimpse of it, and her face sobered instantly.
+
+“Cheerful place!” murmured Latham, glancing up at the dilapidated
+ceiling. “Anyway, we ought to be thankful that the three of us are
+together. Wonder what the amiable ruffians plan to do next. What
+happened to you after you left me, Cole?”
+
+It took Cole some little time to remember, but at length he gave the
+doctor a brief summary of the episode in the tower, ending with the
+unexpected attack that had left him with a swollen jaw. The doctor
+seemed amused.
+
+“Laid them both out, eh?” he said with a chuckle. “Good work, Cole.
+I believe you could manage a massacre all by yourself if you had the
+chance.”
+
+“The chance may come sooner than we think,” said Cole dryly, with a
+glance at the door. “Miss Brownell told me some of the things she has
+learned during her term of imprisonment here. It seems we have one
+advantage, doctor.”
+
+“What’s that?”
+
+“The seventh ingredient.”
+
+A thin smile parted the physician’s lips. “That’s so. I’d forgotten
+about that. It’s a minor detail I worked out independently. Professor
+Carmody made several attempts to make me reveal the secret of it, but
+I refused. You see, by that time I had discovered that the scheme was
+crooked, and I would have nothing more to do with the gang. However,
+the seventh ingredient, as they call it, isn’t of great importance. Its
+value is almost nil.”
+
+“But they seem to think otherwise.”
+
+“They are mistaken, and naturally so. I was mistaken myself for
+a while. I exaggerated the importance of the so-called seventh
+ingredient. Afterward, when I knew better, I saw no reason why I should
+put them right.”
+
+“Glad you didn’t, Latham. As long as they are laboring under a
+misapprehension, we have an advantage over them.”
+
+“How is that?”
+
+“They think you have something that they want. The fact that they are
+mistaken makes no difference. As matters stand at present, you are in a
+position to bargain with them.”
+
+“Bargain over what?”
+
+“Oh, several things.” Cole stepped a little closer to him and spoke in
+an undertone. “Miss Brownell’s safety, for instance.”
+
+Latham’s brows went up. “Of course!” he murmured. “I’m a bit dull
+to-night. Glad you have your thinking cap on, Cole. The amiable
+ruffians will be given to understand that I refuse to discuss the
+seventh ingredient until Miss Brownell is at a safe distance. After
+that nothing will matter. Smoke?”
+
+Cole helped himself to a cigarette from the physician’s case, slanting
+a quick glance in the girl’s direction as he lighted it. She looked
+both puzzled and amused.
+
+“Were you saying something I was not supposed to hear?” she inquired.
+
+The question remained unanswered, for just then the door opened, and
+the gaunt, frock-coated figure of Professor Carmody strutted into the
+room. In his hand was an automatic, which he managed very cautiously,
+and his shrunken face was all smiles.
+
+“Hello, Cole,” he chirped gleefully. “Good evening, Miss Brownell. How
+are you, doctor? Glad to see you all here.” He chuckled wheezily and
+rubbed his bony hands with their talonlike fingers. “Too bad you didn’t
+follow my advice the other day, Latham. You would have escaped a lot of
+trouble if you had been sensible.”
+
+“Go to blazes,” said the doctor contemptuously, advancing a step toward
+Carmody.
+
+The pistol came upward in the professor’s hand. “Don’t move,” he
+warned. “And it won’t do either of you any good to reach for your
+weapons. They were removed while you were—ahem—incapacitated. We object
+to rowdyism in this place. Our leader is a peaceful man and does not
+like disturbances. Cole, you have caused us a lot of embarrassment,
+and see what it has led you to. I believe our last meeting took place
+in room 2512, the Security Building.”
+
+Cole made a wry face as he recalled how the professor had tricked him.
+“You were a bit too clever for me that time, Carmody,” he admitted.
+
+The professor gave a cackling, complacent laugh. “Even an old man like
+me must have his little jokes,” he remarked, still adhering to his
+ludicrous habit of raising and dropping his voice on almost every other
+word. “I’ll wager you don’t know even now what my object was. Eh, Cole?”
+
+Cole measured him with a cool glance. “I think I do,” he declared
+quietly. “The body of Reeves was in the safe. Members of your
+illustrious gang had removed it from its former place and put it there.
+One of my men learned what the safe contained, and he paid with his
+life for his discovery. Later you dropped in to see that everything was
+in readiness to sneak the safe and its contents out of town.”
+
+“You are a very shrewd guesser, Mr. Cole. It is a matter of keen regret
+to me that one of such fine intellect must be on the wrong side of this
+situation. As for the body of Reeves, it will very soon be reduced to a
+handful of fine dust. The process will be scientific in every respect.
+Nothing coarse or gruesome, you understand. We couldn’t have disposed
+of it satisfactorily in the city. It would have been too dangerous.
+But that isn’t what I came in here to talk about. Doctor Latham, you
+were once a friend of mine, and in the beginning of this enterprise
+you gave us several valuable hints. For the last time I ask you to be
+reasonable. It is your last chance.”
+
+“And if I refuse?”
+
+The professor screwed his face into a melancholy expression. “In that
+event you, too, will soon be only a handful of dust.”
+
+“Even so I will have the advantage over you, professor. When your end
+comes there won’t be enough dust to make a thimbleful. I hope I make my
+meaning clear?”
+
+“You will not reconsider your decision?”
+
+“No!” declared Latham explosively.
+
+“Not even in order to save the life of this charming young lady?”
+Carmody turned his beatifically smiling face toward Miss Brownell.
+
+A pallor crept up under the doctor’s eyes. He stared with a horrified
+expression at the professor.
+
+“You mean that——”
+
+“Precisely, my dear doctor. The young lady is dangerous to us.
+Under the circumstances the law of self-preservation demands that
+she be rendered harmless, and the only effective way of doing that
+is to remove her from this sad world. However, in appreciation of
+the services you once rendered us, she shall be spared if you will
+reconsider your decision.”
+
+The doctor appeared to hesitate. His eyes, full of tenderness, were
+fixed on Miss Brownell. Cole could see that he pretended to be
+wavering. Then the girl spoke.
+
+“Doctor Latham has decided,” she declared in a clear, calm voice. “He
+is not the type of man who bargains with blackguards. I wouldn’t permit
+it, even if he were so inclined. Go away!” she added, turning her
+eyes, full of cold contempt, on the professor.
+
+Carmody winced beneath her scornful gaze. For a moment he plucked
+nervously at the lapel of his coat. Then, with a soft chuckle that
+sounded diabolical to the other three in the room, he turned to the
+doctor.
+
+“The young lady has spoken,” he remarked. “I’m afraid her pretty head
+is full of silly notions. Youth is always like that. You are older and
+wiser, Latham. What do you say?”
+
+The doctor regarded him calculatingly. “Just what do you want, Carmody?”
+
+“Ah, that’s better! Getting down to terms, eh? I see I was not mistaken
+in relying on your common sense. You know what I want, doctor. It is
+something we have discussed before. Miss Brownell and Mr. Cole will not
+understand what I mean, but it has something to do with the seventh
+ingredient.”
+
+Latham nodded. “Thought so. Very curious on that point, aren’t you,
+professor? I used all my spare time during three or four months working
+out that interesting angle. It was quite fascinating, I assure you. Do
+you know, professor, I sometimes wonder if the late lamented Doctor
+Price was not about two hundred years ahead of his time? From the very
+beginning of our experiments I suspected that Doctor Price’s secret—the
+secret which he never divulged—was a sort of electronic reaction
+applied to chemical compounds. When I learned how to use that reaction
+in the process we had under way, my problem was solved.”
+
+Carmody regarded him narrowly. “The electron wasn’t known in Doctor
+Price’s day.”
+
+“And that’s why I say he was about two centuries ahead of his time.
+At any rate, I am satisfied he stumbled upon something which closely
+resembles our modern discoveries. Nothing else explains the marvelous
+achievement that he took with him to his grave.”
+
+“And you claim to have resurrected his discovery, Latham?”
+
+“I am not in the habit of making claims,” said the doctor modestly,
+with an air of mysteriousness that was well calculated to impress
+Carmody. “I prefer to let facts speak for themselves.”
+
+Carmody pondered, his sharp, greedy little eyes wandering from one face
+in the group to another.
+
+“You made memoranda of your experiments, of course?”
+
+“Naturally.”
+
+“Where are your notes?”
+
+Latham smiled blandly. “In two places. Here,” tapping his head, “I
+carry the whole process. My written memoranda are in a safe place, a
+place which I shan’t divulge to you until you have given us reasonable
+guarantees in regard to our safety.”
+
+Professor Carmody scowled. “You are hardly in a position to dictate
+terms.”
+
+“Do as you like,” said Latham with a shrug. “If you reject my
+conditions, I shall follow Doctor Price’s example and take my little
+secret with me to my grave.”
+
+“And what about Miss Brownell?”
+
+The physician winced, but before he could answer the girl spoke for
+herself.
+
+“Don’t mind me,” she said spiritedly. “Doctor Latham, why don’t you
+tell the professor that he is beneath contempt?”
+
+Carmody turned his head and regarded her with a look of lofty disdain.
+“Haughty little devil!” he muttered under his breath, then faced
+the physician again. “Well, Latham, what would you call reasonable
+guarantees?”
+
+“Cole and myself will remain here for the present. As far as Miss
+Brownell is concerned, I’ll be satisfied when she telephones me from
+her home in town that she has arrived there safely. Does that strike
+you as reasonable, Cole?”
+
+“Perfectly.”
+
+Carmody scratched his jaw perplexedly. “It is a very difficult
+situation. I shall refer it to the leader of our organization.”
+
+With that he backed cautiously toward the door, his automatic gripped
+tightly in his thin, gnarled hand. In a moment the door closed behind
+him, then came the sound of a heavy bolt turning in the lock, and the
+two men and the girl were alone.
+
+
+
+
+ CHAPTER XXIV
+
+ CORNERED
+
+
+Cole turned to the window and verified his impression that the
+shutters were strong enough to bar their exit in that direction. For
+a few moments he stood there, listening to the remote booming of the
+waves, the fretful whine of the wind, the creaking and groaning of
+timbers in the old house. With these sounds there mingled another, a
+faint but ecstatic humming and whirring that seemed to come from some
+subterranean crypt.
+
+“Gold!” it seemed to say with a dull, sinister intonation. “Gold!”
+
+Cole shrugged and moved away. Next he hurled himself against the
+door, but its solid resistance told him the effort was useless. The
+doctor stood in the middle of the room, pulling thoughtfully at his
+black beard and now and then sending Miss Brownell a glance out of his
+strange, flashing eyes.
+
+“You handled the professor superbly,” Cole told him. “He is guessing
+now, and when a man is guessing he is at a distinct disadvantage.”
+
+The doctor smiled musingly. “But don’t build too high hopes on his
+state of mind,” he cautioned. “It is best not to underrate the enemy’s
+resources.”
+
+“What about that choice morsel you handed him in regard to an
+electronic reaction?” Cole wanted to know. “Anything in it?”
+
+“Absolutely nothing. But it sounded impressive enough to give the
+professor something to worry about. As for Doctor Price, he wouldn’t
+have recognized an electron if he had seen one with the naked eye. I
+hardly expected Carmody to swallow it, but he did. When you tell a fib,
+it is always best to tell the kind that the other fellow is prepared to
+believe.”
+
+Cole laughed; there was something irresistible about the doctor’s
+stoicism. “I hope,” he fervently declared, “that the swallowing of that
+electron will give the professor a severe attack of cramps. What do you
+propose to do next, Latham?”
+
+“Heroics were never in my line,” the doctor asserted in a tone that was
+meant to be cynical. “When one is caught, the thing to do is to yield
+as gracefully as possible. I suggest we surrender to the enemy. Why
+stand on pride when one is headed for a tumble?”
+
+“In other words, you mean to build up a magnificent bluff on the
+electron Carmody swallowed?”
+
+“Precisely,” said Latham, casting a sidelong glance at Miss Brownell.
+
+The girl got up, limped uncertainly across the floor, and placed a hand
+on the physician’s arm.
+
+“You are a good man, Doctor Latham,” she murmured. “You are quite
+transparent, however. You intend to keep up this bluff, as you call it,
+until I am at a safe distance. You fail to consider what is going to
+happen to you and Mr. Cole when they discover you have tricked them.”
+
+“Oh, we will cross that bridge when we come to it,” said Latham with an
+air of profound assurance.
+
+“You aren’t candid with me,” the girl protested. “You know they will
+kill you both as soon as they realize they have been imposed upon. You
+intend to sacrifice yourself for my sake. I won’t have it!”
+
+“Now, Miss Brownell——”
+
+“I won’t accept such a sacrifice,” she declared vehemently. “That’s
+absolutely final.”
+
+Latham gazed at her in an embarrassed way. He tried to smile, but it
+was a pathetic effort. “Youth is always that way,” he declared. “Always
+butting its head against stone walls. Don’t you see, Miss Brownell,
+that——”
+
+“No, I don’t,” she interrupted. “And, so you won’t be tempted to give
+it for my sake, let me tell you that I intend to fight this crowd of
+cowardly ruffians till the end. Even if you should surrender, I would
+not, so your sacrifice would be in vain.”
+
+Latham stroked his beard reflectively. A flippant remark was on the tip
+of his tongue, but he seemed unable to utter it. He assisted the girl
+back to her chair.
+
+Cole had watched them in silence. Something stirred gently within him
+as he witnessed the scene between the doctor and the girl. There was
+a touch of the sublime in the physician’s determination to sacrifice
+himself for the object of his hopeless devotion. But to Cole it all
+seemed very futile. He doubted strongly that the leader of the gang
+would accept Latham’s terms. Knowing that she had discovered several
+important things in regard to the organization’s activities, they would
+not be likely to let the girl out of their clutches. Their logical
+move would be an effort to obtain by other means the secret which they
+supposed was in Latham’s possession. Nevertheless, the little drama
+enacted before his eyes touched him deeply. Now he shrugged off his
+hopeless feeling and strode briskly across the floor.
+
+“It isn’t time to sing the funeral hymn just yet,” he declared. “There
+is another fight in us still. I propose that we——”
+
+What he had to propose was not made clear, for the door opened, and
+with his usual stiff and dignified gait Professor Carmody walked once
+more into the room. He had dropped his mock affability and carried
+himself with a stern and dignified air.
+
+“I have talked with the chief,” he announced, addressing Doctor Latham.
+“The arrangement you suggested is flatly impossible.”
+
+“Just as I thought,” muttered Cole under his breath.
+
+“You can see for yourself how unreasonable it is,” Carmody went
+on in an argumentative tone. “Miss Brownell is in possession of
+information which, if used against us, might harm us greatly. Under the
+circumstances it would be extreme folly on our part to permit her to
+leave this place for the present.”
+
+“Then what do you propose?” asked the doctor.
+
+“That you listen to reason. In a few days, a week or two at most, our
+present enterprise will be finished, and we shall be in a position
+where nothing can hurt us. You, Latham, can hasten developments, if you
+wish, by giving us the formula you have worked out. It isn’t essential,
+but we prefer to make use of it. The sooner you choose to oblige us,
+the sooner you and your friends will be permitted to depart.”
+
+The doctor regarded him with a half-humorous, half-contemptuous gaze.
+“Is that all?”
+
+“By no means. If you decide to accommodate us, you shall share in
+the golden harvest we soon expect to reap. Think of it, Latham. By
+complying with a simple request you will make yourself enormously
+wealthy. Never before in the world’s history was such a magnificent
+reward offered for a comparatively small service. Never since——”
+
+“You are waxing rhapsodical, professor,” interrupted Latham curtly. “I
+am always suspicious of a man who makes flowery promises. Will you tell
+me in plain words—the plainer the better—what will happen if I should
+reject your magnanimous offer?”
+
+“I do not like to contemplate it,” said Carmody, his face full of
+sadness. “Especially in view of Miss Brownell’s connection with the
+matter. But you will not do anything so foolish, Latham. Remember
+that we are powerful enough to get what we want, and that we do not
+hesitate to use extreme measures when necessary. We can bend even such
+a stubborn will as yours. I am waiting for your answer. Will you give
+us the formula voluntarily, or must we resort to unpleasant forms of
+coercion?”
+
+Maintaining a firm hold on his pistol, he struck an expectant attitude.
+Cole, who had remained a silent but attentive listener, could see that
+Latham’s position in the scientific world, together with the work he
+had previously done for the organization, had convinced the professor
+that he really possessed a formula that would be of great value to
+the gang. Latham, on the other hand, seemed in a quandary as to how
+he might best use his precarious advantage. Already it was slipping
+away from him, and soon, unless an unforeseen development came to his
+rescue, it might be turned against him.
+
+“You are taking a long time,” complained the professor.
+
+“It is a weighty question,” rejoined Latham.
+
+“Perhaps I can help you to arrive at a decision,” said Carmody, a
+faint, cruel smile parting his bloodless lips. Suddenly he shifted the
+aim of the pistol so that the barrel pointed straight to Miss Brownell.
+“I believe you are a man of your word, Latham. I shall count ten.
+Unless you give me a favorable reply before I reach ten, Miss Brownell
+will go to a better world.”
+
+The sardonic grin that had twisted the doctor’s lips froze into a
+ghastly look of horror. Miss Brownell straightened a little in her
+chair, her face turned a shade paler, but there was no fear in the
+eyes she leveled at the professor. Critical as the moment was, Cole’s
+dominant sensation was admiration for her courage.
+
+Carmody began to count in his thin, brassy voice: “One—two—three—four——”
+
+Cole gazed narrowly into his face, as impassive as if carved out of
+wood. There seemed to be no doubt but what Carmody meant to carry out
+his monstrous threat. He flexed his muscles for a spring while the
+professor went on counting.
+
+“——five—six—seven—eight——”
+
+Cole lunged forward, staking everything on the chance of snatching
+the murderous weapon from the professor’s hand, but Doctor Latham
+acted even more quickly. With a sudden bound he crossed the floor and
+placed himself directly in front of the chair in which the girl sat.
+For a moment the pistol pointed straight at his midriff; then, with an
+exclamation of baffled rage, Carmody lowered the weapon.
+
+“Fool!” he snarled. “Step out of the way this instant, or I’ll kill
+both of you.” Once more the pistol rose in his hand.
+
+Very calmly, while Cole marveled at his audacity, Latham took a case
+from his pocket and with ostentatious serenity lighted a cigarette.
+
+“Fire away,” he said coolly, folding his arms across his chest and
+smoking with an air of perfect content.
+
+Carmody regarded him with a baleful glare, then abruptly changed his
+mind and started backing toward the door. He slammed it behind him with
+unnecessary vigor, and they heard the bolt slide in the lock. Latham
+flung away his cigarette.
+
+“Whew!” he exclaimed. “That was fairly exciting. I didn’t like the way
+Carmody looked when he left us, though. The old rat has something up
+his sleeve.”
+
+Cole nodded, wondering at the meaning of the professor’s hasty exit.
+“Our only hope is to spar for time, and we have been fairly successful
+so far,” he remarked. “That was a neat maneuver, Latham.”
+
+“It was splendid!” exclaimed the girl, and Cole noted a new expression
+in her wide, lustrous eyes as she fixed them on the physician. “But you
+mustn’t do it again,” she added firmly. “He might shoot next time.”
+
+“How is the foot?” inquired Latham.
+
+“Better—much better. I think I can step down on it now.”
+
+“You had better not try as yet,” said the physician with a professional
+air. “Cole and I may challenge you to a foot race by and by, and you
+must preserve your energies.”
+
+She merely smiled at this, and again Cole noted the new, tender
+expression in her face. He was about to frame a remark, but just then
+the door opened. Two burly, hard-faced men, each with an automatic in
+his hand, entered the room.
+
+“The big chief wants to see you,” announced one of them. “This way.” He
+pointed toward the open door.
+
+Cole glanced narrowly at the weapon in his hand, then decided that
+at the present moment resistance would be worse than useless. There
+were other lives besides his own to be considered. Evidently the same
+thought had occurred to the doctor. After a moment’s hesitation and an
+exchange of glances with Cole, he took the girl in his arms and carried
+her out followed by Cole.
+
+One of the armed men, walking at the head of the little procession,
+opened the door.
+
+“In there,” he directed. “Step lively!”
+
+He gave Cole an ungentle shove with his automatic, and the three
+prisoners walked through the door.
+
+
+
+
+ CHAPTER XXV
+
+ FACE TO FACE
+
+
+Cole glanced about the room they had entered. Its sparse furnishings
+suggested that it had been arranged in haste. There were a desk and
+a telephone, hinting that it served as the executive office of the
+gold-mad crowd, also a few chairs, a huge steel safe, and a cot. The
+cluttered condition of the desk indicated that some one had recently
+been sitting there and would probably soon return. Cole’s gaze rested
+longingly on the telephone, the only connecting link with the outside
+world.
+
+Very gently Doctor Latham placed the girl in one of the chairs. As she
+looked up at him, her eyes were full of trust and gratitude.
+
+The doctor turned to one of the armed guards at the door.
+
+“Where is the benevolent gentleman whom you call the big chief?” he
+inquired.
+
+“You’ll see him soon enough,” replied the man surlily.
+
+“Good!” exclaimed Latham. “At last my curiosity shall be satisfied. We
+have a pretty good idea what he looks like—eh, Cole?”
+
+“I think we do,” said Cole, a smile tugging at his lips. “Once or twice
+before my suspicions turned in the direction of the man I have in mind,
+but something threw me off the track. Now I am almost sure.”
+
+Cole’s next words were spoken in an undertone, too low for the girl to
+hear. “You realize what you are up against, don’t you, Latham?”
+
+“Against a bunch of cockeyed devils, of course.”
+
+“I had something more specific in mind. Professor Carmody has failed
+to bully us, so now the big chief himself is to have a try at it. You
+realize, of course, that he wouldn’t allow himself to be seen by us
+unless——” He paused and looked gravely at the doctor.
+
+“Yes, I understand,” whispered Latham, throwing an uneasy glance at
+Miss Brownell. “He wouldn’t show himself to us if he thought there was
+the slightest chance that we would ever tell tales about him. These
+scoundrels are planning to murder us, Cole.”
+
+“So it looks, but not until they have made one more effort to make you
+reveal the formula for the seventh ingredient.”
+
+There was a look of sad humor in the doctor’s eyes. “And next time they
+will try harder. I’ll keep up the bluff as long as I can. The seventh
+ingredient!” He chuckled grimly under his breath. “Like most humbugs,
+it sounds well.”
+
+Cole glanced expectantly toward the door. “A little while ago, out in
+the other room, when you stepped between Carmody’s pistol and Miss
+Brownell, did you expect the professor would shoot?”
+
+“I didn’t know what to expect, to tell the truth.”
+
+“Well, I knew he wouldn’t,” said Cole emphatically. “While we are
+waiting, you might try to figure out the reason why. When you find it,
+file it away in your mind for future reference. It may come in handy.
+We must stop this whispering. We are making Miss Brownell nervous.”
+
+A slight sound was heard in the corridor. The two armed guards stood
+aside, and then the door opened. A moment later, smiling thinly as he
+saw his suspicions confirmed, Cole faced the leader of the alchemists.
+
+“Good evening, Mr. Englebreth,” he said easily.
+
+An attendant pushed the invalid’s wheel chair up to the desk.
+Englebreth, his disproportionately broad shoulders slightly hunched,
+looked about the room with a rather listless expression. He was as
+white-faced as ever, and his pale, washed-out eyes showed little
+animation, but a faintly sinister smile played about the long, thin
+lips. In his hand was a pistol with which he toyed with apparent
+carelessness.
+
+He nodded at Cole, then, with a quick motion of his long, slim fingers,
+dismissed his attendant. The door closed, and the two armed guards
+stood in front of it. For a while no one spoke. A hush seemed to have
+descended over the little group with the invalid’s entrance. Latham
+regarded him intently, but without a sign of surprise. For a moment
+Englebreth’s pale eyes rested on Miss Brownell, then he glanced at the
+doctor, and finally at Cole. His forehead puckered a little.
+
+“You do not seem surprised to see me,” he remarked petulantly, as if
+disappointed that his entrance had created no sensation.
+
+“Why should I be?” Cole asked.
+
+“Surely you didn’t suspect until now that I was connected with the
+enterprise on foot here?”
+
+“On the contrary,” said Cole, “your entrance has only confirmed the
+suspicions that have been running in and out of my head for the past
+two days. They began when I saw you enter the offices of the Bureau of
+Civic Research. They received a setback when I learned that the letters
+you left on the desk were genuine.”
+
+Englebreth seemed mildly amused. “I am a public-spirited man,” he
+declared. “The Bureau of Civic Research is one of the numerous
+praiseworthy activities I am interested in. Being one of its honorary
+vice presidents I have free access to its headquarters, of course. When
+I learned, quite by accident, that a certain mysterious organization,
+located on the top floor of the building, was resisting my plans, then
+this privilege stood me in good stead. You might have guessed, Cole,
+that I left those letters for a blind, just to show any casual visitor
+that everything was open and aboveboard.”
+
+“I might,” said Cole dryly.
+
+“Yet you have proven yourself a very fair guesser, I must say. You are
+a clever fellow, Cole. The Unknown Seven didn’t become really dangerous
+to us until you took charge of its activities. Not that you have
+accomplished anything,” he added with a dry chuckle. “We are too strong
+even for you.”
+
+Cole received the compliment with a shrug. A silence fell between them.
+In the stillness the rhythmic humming of machinery was distinctly
+heard. In Cole’s ears it sounded like a pæan of gold. He looked deep
+into Englebreth’s pale eyes. There was a queer flicker in the depths,
+an expression of insatiable greed to which the subterranean whir
+and throw was but the audible accompaniment. He had seen the same
+expression in Reeves’ burning orbs and also in the eyes of Carmody and
+Ballinger. There was something abysmal about it. It suggested one who,
+having gazed too long on visions of great wealth, had become enslaved
+to a fearful obsession.
+
+“Yes, you are very clever,” Englebreth went on. “It did not occur to me
+that any one might suspect what the safe contained, but evidently you
+did. You followed the yacht, of course. It was a very ingenious move,
+Cole. Without doing so you would never have located our establishment
+here. Now that you are here what do you propose to do?”
+
+Cole only smiled. Again he looked deep into Englebreth’s eyes and saw
+the smoldering fires of the fever of gold.
+
+“My wife is an admirer of yours, Cole,” the invalid went on. “When her
+brother disappeared she insisted that I engage you to find him. Of
+course I couldn’t very well refuse. It would have looked suspicious,
+and, besides, I supposed you were harmless. When I saw that you were
+about to learn too much, through your connection with me, I succeeded
+in persuading my wife that you were not worthy of confidence, that it
+was best to dismiss you. Again I ask you what you intend to do.”
+
+The words sounded like a taunt. Again Cole slanted a glance at the
+telephone. The instrument tantalized him. He noticed that the green
+cord attached to its base was of generous length. His mind worked
+quickly, but the sight of the three automatics baffled him. A sudden
+move would mean instant death, not only for himself, but for his two
+companions as well.
+
+“You seem irresolute,” Englebreth observed. “And no wonder, Cole. For
+once in your life, you are absolutely helpless. You have been entirely
+too meddlesome, and people who meddle in others’ affairs usually get
+into trouble. Listen!”
+
+Cole listened. A faint smile played about Englebreth’s lips as the
+whirring of machinery sounded clearly in the surrounding silence.
+
+“Know what it means, Cole. It means gold! Gold!” His lips seemed to
+caress the word. “Millions and millions and millions, Cole. After you
+are gone we shall be turning out gold in unlimited quantities. I and my
+associates shall be the richest men in the world. And you, poor worm,
+who thought you could stop us, will be reduced to a few grains of dust.”
+
+“Sure of that?” demanded Cole.
+
+His tone, clear and confident, seemed to impress the invalid.
+
+“Why do you ask? Surely you don’t expect to escape from your present
+predicament. As it happens, all the members of my organization are here
+to-night. A touch of my finger will summon twenty men to my assistance,
+if necessary.”
+
+He scanned Cole’s face for a sign of fear, but none came. The other’s
+coolness seemed to nettle him.
+
+“So the gang is all here,” said Cole carelessly. “That means, of
+course, that Doctor Ballinger is included?”
+
+“Naturally. An excellent man, Ballinger. He has a practical mind, and
+he knows on which side his bread is buttered. Why do you ask?”
+
+“I am glad he is here,” said Cole. “I wouldn’t want him to get away
+from me, you know.”
+
+The invalid leaned out of the chair and stared. “Get away?” he echoed.
+“What do you mean?”
+
+“I have a particular score to settle with Ballinger,” said Cole calmly.
+“Naturally I want him present when I hand you and your gang over to the
+police.”
+
+“When you——” Englebreth was utterly astounded. “If you think this is a
+joking matter——”
+
+“I was never more serious in my life, Englebreth. Before daybreak I
+expect to hand every mother’s son of you over to the authorities.”
+
+Englebreth stared for a moment longer; then he laughed hoarsely. Cole
+could see that his cool insolence had exerted the intended moral
+effect. The invalid, though the advantage was all on his side, felt
+just a trifle ill at ease. Cole’s demeanor was well calculated to
+suggest that a surprise of some sort was forthcoming. Englebreth would
+not have been human if he had failed to be impressed by the airy
+assurance of one whom he thought wholly at his mercy.
+
+Finally he shrugged. “You must be mad,” he muttered. Then he faced
+Latham, who stood beside the chair in which Miss Brownell sat. “I have
+something to say to you, doctor. You did us a service once, and that is
+something I never forget. If you will——”
+
+“Save your breath,” interrupted Latham contemptuously. “For a time, a
+little while ago, I was tempted to enter into negotiations with you,
+but Miss Brownell wouldn’t hear of it. What is a mere man to do when a
+woman sets her foot down?”
+
+“Your flippancy is ill-timed,” said Englebreth austerely.
+
+“Hasn’t one a right to joke at one’s own funeral?”
+
+“We shall see.” Englebreth’s lips tightened ominously. “You know what
+we want from you, doctor. Only a formula that by right belongs to us,
+since you worked it out while you were a member of this organization.
+Produce it, and I promise to be lenient with you and Miss Brownell.
+Unless my senses deceive me”—and Englebreth smiled craftily—“you are
+very anxious that nothing unpleasant shall happen to her.”
+
+Latham hesitated, impressed by the cruel smile on the invalid’s lips,
+and the girl answered in his place.
+
+“Doctor Latham’s answer is _no_,” she declared emphatically.
+
+Englebreth regarded her curiously, with an odd mingling of admiration
+and malice. “You are a stubborn young person,” he muttered. “For the
+last time, doctor, I ask you if you will consent to my terms.”
+
+Again it was Miss Brownell who answered. “Doctor Latham refuses,” she
+declared. “He knows that your promises are worthless, that you intend
+to kill us regardless of whether or not he grants your request. I don’t
+think there is anything further to be said.”
+
+“No?” Englebreth’s thin fingers seemed to tighten around the pistol.
+“Perhaps I can convince you——”
+
+He stopped short. A squeallike cry of astonishment escaped him, for
+Cole had just done a very unexpected thing. It was so unexpected,
+in fact, that it seemed like the act of a person whose reason was
+tottering. With arms folded across his chest he had casually approached
+the chair in which Miss Brownell sat. For a time he had seemed absorbed
+in deep thought, but all the while he had been scheming how he might
+divert Englebreth’s attention, even if only for a moment, from the
+menacing pistol in his hand. Anything of a startling nature, the more
+bizarre and ludicrous the better, would serve his purpose. Now he
+turned suddenly and gave the girl a resounding slap on the cheek. He
+followed it up with another, then with a third.
+
+A spell seemed to fall over the gathering. They had witnessed an act,
+in itself trivial and ridiculous, that staggered their reason by its
+sheer fatuity. For a measured moment their minds were at a standstill.
+That was exactly what Cole had intended, and a moment was all he
+needed. He had acted on a fugitive inspiration at a time when all
+seemed lost, when a move of a more rational nature would only have
+hastened the inevitable.
+
+The resounding smack of the third blow had scarcely drifted out on the
+silence when he leaped at the invalid’s chair. In an instant, while the
+minds of Englebreth and the two guards at the door were still dazed
+from contemplation of a thing so bizarre, he had snatched the pistol
+from the cripple’s hand. A moment later he was crouching low behind
+Englebreth’s chair, pressing the muzzle of the weapon against his back.
+
+He thrilled inwardly. Once more his mind had triumphed over a critical
+situation. The other time had been when he faced Professor Carmody in
+the Bureau of Civic Research. The professor had been thrown off his
+mental base by a trick just as simple and effective.
+
+“Tell your men to drop their weapons,” he commanded, the muzzle of the
+pistol prodding Englebreth’s back. “I’ll give you exactly ten seconds.
+Unless you obey, you will be a dead man.”
+
+Englebreth squirmed in the chair, evidently in a state of great terror.
+In a few minutes his agile mind might reassert itself, but just now
+he was merely a shivering wreck. His trembling hand went up and made
+a signal to his men just as Cole was about to call time. Habitually
+obedient to the master will, the men at the door dropped their pistols.
+
+Cole rose from his crouching position behind Englebreth’s chair. Latham
+and the girl stared at him bewilderedly, the latter moving her hand
+dazedly over the cheek that Cole had struck, both seemingly unable to
+realize as yet what had happened. Englebreth was breathing raspingly.
+The two guards at the door gazed dully at the erect figure behind the
+invalid’s chair.
+
+“Pick up those pistols, Latham,” said Cole quietly. “Pardon my
+rudeness, Miss Brownell. It was necessary.”
+
+She smiled uncertainly, evidently beginning to understand. It was
+several moments before the physician could shake off his stupefaction.
+He moved haltingly over the floor and dazedly took possession of the
+pistols.
+
+“It was magnificent, Mr. Cole!” murmured the girl, at last grasping the
+psychological stratagem by which Cole had reversed the situation.
+
+“But if I hadn’t seen it happen, I would have sworn it couldn’t be
+done,” said Latham.
+
+Cole’s face was grave. His ruse had only averted their immediate
+danger. Any moment other members of the organization might pour into
+the room, crushing them by superior numbers. Every second counted now.
+Holding the pistol in one hand, Cole drew the telephone to him and
+spoke a number in the transmitter. Only a few words would be needed to
+make Carlin understand the situation, and within an hour reinforcements
+would arrive. He wondered, as he waited for his connection, if they
+could hold out until then. Impatiently he jigged the hook, muttering
+heartfelt imprecations upon the state of the rural telephone service,
+and then, in a twinkling, something happened.
+
+He saw the cripple’s weazened hand move stealthily along the side of
+the desk, became conscious that a heretofore unnoticed door had burst
+open behind him, heard the girl’s quick, startled cry, saw the light
+blotted out as if a pall had suddenly dropped over the little room,
+felt a stinging blow at the back of the head, and, with Englebreth’s
+diabolic chuckles dinning in his ears, fell to the floor.
+
+
+
+
+ CHAPTER XXVI
+
+ A CRY
+
+
+“Gold! Gold!” The vibrant murmurs, edged with a triumphant and sinister
+note, echoed in Cole’s ears as he opened his eyes. The house was
+shivering with a slow, rhythmic tremor, a throbbing pulsation that
+instantly began to pierce the fog in his mind.
+
+From his recumbent position on the floor he struggled to a sitting
+posture. Lifting his head, he listened to the grimly exultant pæan
+rising from the bowels of the earth.
+
+“Feeling better?” asked a voice which he vaguely recognized at Doctor
+Latham’s.
+
+Cole did not answer. The subterranean vibrations seemed to cast a spell
+over his awakening senses.
+
+“Hear it?” he asked at length.
+
+“Hear what?”
+
+“This infernal hymn of gold. It will drive me crazy if I have to listen
+to it much longer.”
+
+“Then don’t listen. Know what time it is?”
+
+Cole shook his head as if to indicate that the matter was of absolutely
+no importance.
+
+“Precisely twelve o’clock,” said the doctor, and Cole heard something
+resembling the snapping of a watch lid. “You have been unconscious for
+something like ten hours. That was the second knock-out in a night,
+Cole. Why can’t these scoundrels show a little versatility?”
+
+“What happened?” asked Cole dully.
+
+“As if that mattered now! Englebreth gave a signal of some sort, and
+the next thing I knew about half a dozen of his hired thugs swooped
+down on us. My recollections cease at that point.”
+
+“Where are we?”
+
+“In the same room we occupied last night, before we were ushered into
+Englebreth’s august presence. The windows are just as tightly shuttered
+as they were then, and the door is just as impregnable. I wonder if
+these hounds mean to let us starve to death.”
+
+Cole looked about him. An electric light was burning dimly over their
+heads. Through a narrow rift in one of the shutters came a shaft of
+sunlight, gilding the dust in the stale air.
+
+“Where is Miss Brownell?” he asked abruptly.
+
+“Wish I knew,” muttered the doctor. Of a sudden all the levity had died
+out of his voice. “You and I were alone in this room when I came to. If
+these rats harm a single hair on her head——” The threat died unfinished
+in a groan.
+
+With difficulty Cole rose to his feet and leaned against the wall.
+
+“I don’t seem to remember just where we were at,” he mumbled.
+
+“You gave Miss Brownell a slap on the cheek,” the doctor reminded him.
+“It was a brilliant idea, Cole.”
+
+“So it was—but it failed, as I remember,” Cole muttered grimly. “What
+was the situation just before that?”
+
+“Englebreth was doing his level best to bluff me into revealing the
+formula of the mythical seventh ingredient. Perhaps you remember his
+sportsman-like proposition. I was to give him the formula in return for
+my life.”
+
+“He would promptly kill you the moment you surrendered the formula,”
+Cole pointed out.
+
+“Without a doubt. He would kill all three of us. But, as it happens, I
+can’t give him the formula, because it doesn’t exist.”
+
+“But as long as he thinks it does, we are holding a trump card in
+reserve,” said Cole, regaining his grip on the tangled threads of the
+situation.
+
+“If only we knew how to use it!”
+
+“We’ll find a way,” said Cole confidently, dragging himself to a chair
+at one side of the room. “Anything about your person that could be used
+as a weapon in an emergency?”
+
+“Not a thing. I am plucked clean.”
+
+“So am I,” said Cole after a hasty survey of his pockets. “No, here is
+a stick pin. They seem to have overlooked that. The pin is long and
+sharp. You could pierce a person’s jugular vein with an implement of
+this kind, couldn’t you, doctor?”
+
+“If you knew exactly where to strike.”
+
+“You do, of course, being a doctor. As a weapon it would be useless in
+my hand, so I will transfer it to you. I suggest you conceal it under
+the lapel of your coat.”
+
+Puzzled, Latham took the ornament and did as Cole had directed. As he
+hid it under his lapel, he seemed inclined to ask a question, but Cole
+forestalled him.
+
+“I think some one is coming,” he remarked in an undertone.
+
+Latham, listening, heard the sounds which Cole’s keener ears had caught
+first. Folding his arms across his chest, he struck a carefree pose and
+looked toward the door. It opened, and two armed stalwarts walked in.
+They were followed by Englebreth in his wheel chair. Two more guards,
+also armed, brought up the rear. With a cautious look to all sides,
+the invalid trundled his wheel chair into the center of the room. The
+barrel of a small automatic gleamed viciously in the electric light.
+
+“How do you do, gentlemen?” he said in tones of mock geniality. “Wish
+I could offer you some breakfast, but it has been my experience that
+people are always more reasonable when their stomachs are empty. I have
+come to renew our discussion where we left off last night.” He fixed
+his bleak and very alert eyes on Doctor Latham.
+
+“Better save your breath,” suggested the physician. “You may need it
+before we are through with you.”
+
+Englebreth smiled serenely. “I don’t blame you, doctor, for trying
+to bolster up your courage. People usually resort to false bravado
+when they are hopelessly situated. Our friend Cole enacted quite a
+spectacular scene last night, but he will hardly try anything like that
+again. He has learned his lesson. Well, doctor, are you ready to oblige
+us?”
+
+“If you will drop that automatic, I’ll oblige you with a smash on the
+jaw,” said the physician in unprofessional but impressive language.
+
+“Still stubborn, I see.” His smile took on a sinister quality. “I
+suppose you are wondering what has become of Miss Brownell?”
+
+The doctor bit his lip, but his gaze did not waver. “If anything
+happens to Miss Brownell,” he muttered hotly, “I’ll choke you to death
+with my bare hands.”
+
+“Save your threats, doctor. They don’t interest me in the least. As
+yet nothing whatever has happened to Miss Brownell, but something will
+unless you adopt a more reasonable attitude. I warn you that it will be
+something decidedly unpleasant.” He turned slightly in the chair and
+addressed one of his bodyguards. “Ask Doctor Ballinger to step in here.”
+
+The man nodded and left the room. A questioning glance passed between
+Latham and Cole, the former looking as if a dread suspicion had
+suddenly occurred to him. In a few moments the messenger returned with
+Ballinger. The physician strode in with a jaunty air and saluted Cole
+and Latham with exaggerated politeness.
+
+“Ah, Ballinger,” said the cripple in an undertone, yet loud enough for
+the two prisoners to hear, “I just wished to make certain that you have
+made all necessary arrangements for the—ahem—experiment we discussed
+last night.”
+
+Cole, casting a sidelong glance at Latham, saw him stiffen suddenly. A
+film of pallor spread above the bearded portion of his face.
+
+“Yes, everything is ready,” announced Ballinger.
+
+“The instruments came?”
+
+“Just a little while ago.”
+
+“And the ether?”
+
+“It is here too.”
+
+“Good, Ballinger. Be ready to proceed the moment you hear from me.” He
+waved a withered hand in dismissal.
+
+Ballinger, an inscrutable smile playing about his lips, left the room.
+An intense silence followed. The cripple’s gelid gaze moved from Latham
+to Cole, and then back to Latham.
+
+“You understood?” he asked.
+
+Neither man answered. A harrowing suspicion seemed to have come over
+both of them. Latham looked as if his powerful body was racked by an
+agonizing dread.
+
+“Ballinger is a very clever man,” murmured the invalid. “You know
+what happened to Malcolm Reeves.” He paused, looked stonily at Doctor
+Latham, as if waiting for his last words to produce their utmost
+effect. “The same thing,” he added slowly, measuring each word, “will
+happen to Miss Brownell unless you change your mind, Latham.”
+
+A cry of mingled horror, loathing and hate broke from Latham’s
+compressed lips. He sprang toward the cripple, hand raised as if to
+strike, but in an instant two of the bodyguards intervened.
+
+“Glad we understand each other, Latham,” said the cripple calmly. “The
+operation will start in fifteen minutes unless you submit to my terms.”
+
+Latham stood speechless. The only sound heard in the room was a great
+sigh.
+
+“Don’t like the idea, eh, Latham?” the invalid went on in smooth,
+dulcet tones. “The spectacle of Miss Brownell reduced to a gibbering
+lunatic is a little too much for your imagination to dwell on. You have
+a vivid recollection of what happened to Reeves.”
+
+A dull, hoarse groan sounded in the physician’s chest. Cole, watching
+him, thought he was about to give way under an overwhelming strain.
+
+“You’re mistaken, Englebreth,” he managed to say. “There is no such
+thing as the seventh ingredient. I let you go on thinking so because——”
+
+Englebreth interrupted with a wave of his hand. “I expected you to
+say that. It would be your logical evasion. You can’t deceive me with
+such nonsense. Only last night you discussed the possibilities of the
+seventh ingredient with Professor Carmody. As he explained it to me,
+it’s a sort of electronic reaction. Not being a scientific man, I don’t
+understand what that means, but it doesn’t matter. I have the utmost
+respect for your scientific achievements, doctor. Will you give us the
+formula?”
+
+Latham fumbled in vain for a convincing argument. His advantage had not
+only slipped away from him, but it had become a deadly boomerang in
+Englebreth’s hand.
+
+“I swear I am telling you the truth!” he cried brokenly.
+
+A cold smile curled the cripple’s lips. “Such childish subterfuge
+doesn’t go with me,” he said contemptuously. “Either you give me the
+formula instantly, or Miss Brownell will be a lunatic inside of an
+hour. Take your choice.”
+
+He leaned back in the chair, slowly and playfully twisting the
+automatic in his hand. Cole stepped forward.
+
+“Latham has told you the truth,” he declared. “The seventh ingredient
+never existed outside of his imagination.”
+
+Englebreth shrugged with an air of utter incredulity. Cole could see
+that there was no way of disturbing his firmly rooted belief. And he
+knew that, even if the seventh ingredient had been a reality, Latham’s
+submission would not have altered their situation.
+
+Englebreth looked at his watch, then summoned one of his bodyguards and
+whispered something in his ear. The man left the room. The slamming
+of the door sounded like a death knell in the tense silence. Latham’s
+chest heaved in a frenzy of suppressed emotions. Minutes passed, and
+then hurried footsteps sounded overhead, accompanied by the sound of
+a resisting body being dragged over the floor. Latham, with a wild
+look in his face, started forward, but one of the guards shoved him
+back. Breathing fast and raspingly he swayed unsteadily on his feet.
+Of a sudden he gave a violent start, then stood as if frozen into
+immobility. From the room above came a long cry of terror, uttered in a
+woman’s voice.
+
+Latham’s bulging eyes stared upward. There was a look of insanity in
+his face.
+
+“Stop it!” he cried hoarsely. “For God’s sake——”
+
+Another cry, more poignant than the others, shrilled through the house.
+
+“Stop it—you fiend!” cried Latham.
+
+“I will, on one condition,” said Englebreth calmly. “There is still
+time. They are only making preparations upstairs. She won’t cry when
+the real business begins.”
+
+Latham’s hand went to his eyes as if to exclude a hideous vision.
+
+“Careful, Englebreth!” said Cole evenly. “If you go too far, Latham may
+lose his mind.”
+
+“And if he does, what then?” demanded the cripple jeeringly.
+
+“A number of things may happen.” Cole gave the physician a level,
+significant glance. “For instance, Latham may take it into his head to
+kill himself.”
+
+The physician’s head went up. His hands left his face. A look of
+dawning comprehension crept into his features. He turned his head and
+for an instant his eyes met Cole’s, reading a message there.
+
+“Kill himself?” echoed the cripple, astonished. “What rot, Cole! How
+would he do it, and why?”
+
+“Ask him,” said Cole with a careless gesture. “I can only point out to
+you that if he kills himself the secret of the seventh ingredient dies
+with him. Look! He is——”
+
+He simulated a cry of astonishment and horror. Latham, quickly
+interpreting the message he had read in Cole’s eyes, had snatched the
+stick pin from under the lapel of his coat.
+
+“Watch me, Englebreth,” he declared in a voice that had suddenly
+retrieved all its lost vigor. “Even a stick pin makes quite a
+formidable weapon if it’s pointed in the right direction. I am pointing
+this one straight at my jugular vein. The moment anybody in this room
+makes a move, I drive it in. Where will your seventh ingredient be
+then, Englebreth?”
+
+The cripple stared at him in speechless bafflement. He raised a hand,
+but it fell limply to his side.
+
+“You—you’re crazy!” he stuttered.
+
+“Maybe,” said Latham coolly.
+
+“Or else you are only bluffing.” There was a trace of doubt in
+Englebreth’s tones.
+
+“Why should I be bluffing? I would rather kill myself than be killed by
+your bunch of hyenas. I know you meant to kill me, anyway, Englebreth.
+One thing is certain. Unless you stop the preparations upstairs within
+the next sixty seconds, your last hope of obtaining that formula will
+be gone. You can’t get anything out of a dead man.”
+
+Englebreth strained forward in his chair, staring into the physician’s
+grim, determined face.
+
+“He means what he says,” Cole declared, smiling despite the tension of
+the moment. “You will have to act quickly, Englebreth.”
+
+The cripple considered a moment longer, then bawled an order to one
+of the men at the door. The fellow hurried away, and in a moment
+they heard him scurrying up the stairs. An exchange of words sounded
+overhead, then all was quiet.
+
+Englebreth made an impatient gesture with his hand. The bodyguard
+closed in around him, and with petulant motions he wheeled himself out
+of the room. At the door he turned his head for a moment, and a little
+chill rippled down Cole’s back as he saw the cold, malignant look in
+the cripple’s eye.
+
+
+
+
+ CHAPTER XXVII
+
+ THE WAY OUT
+
+
+Doctor Latham stroked his beard thoughtfully as the door closed behind
+the invalid and his retinue. “It worked like magic,” he remarked.
+
+“It worked,” Cole amplified, “because we were dealing with a logical
+mind, one that deals mainly with reason and fails to consider the human
+equation. We know that Englebreth means to kill us in the end, and he
+knows that we know it. That being the case, it wasn’t hard for him
+to put himself in your place a little while ago. He would have done
+what you threatened to do, because it was the logical move under the
+circumstances. I wonder what deviltry Englebreth will be planning next.”
+
+“A seven-course dinner, I hope,” said the doctor wistfully. “I’m
+famished.”
+
+Cole regarded him musingly, marveling at the resiliency of his spirits.
+Latham appeared to have shaken off all external cares the moment he saw
+that Miss Brownell was no longer in immediate danger.
+
+“You might as well restrain your appetite, doctor,” he murmured. “You
+heard what Englebreth said, that a man is most amenable to argument
+when he is hungry. At any rate, it is worth something to know that he
+doesn’t want you to die just yet. He showed that plainly when you made
+that monumental bluff with the stick pin. I saw him turn white as a
+ghost.”
+
+“Thanks to the seventh ingredient,” said Latham with a chuckle. “It’s
+the best kind of life insurance, but I fear it won’t last long. Any
+more tricks in your repertory, Cole?”
+
+“One more, I think.” Cole glanced toward the shadowy corner where he
+had stood during Englebreth’s presence in the room. “I understand,” he
+went on casually, “that Dutchess Point was once a very gay place.”
+
+“If so, its gayety hasn’t improved with age.”
+
+Cole ignored his flippancy. “I’ve been told it was once a notorious
+gambling resort. Places of that kind are usually equipped with
+contrivances for making hasty exits—trapdoors, sliding panels and that
+sort of thing.”
+
+Latham raised his brows. “What are you getting at?”
+
+But Cole seemed in no hurry to approach his subject. “Ever notice,
+Latham, that many people find it very hard to remain motionless when
+they are in a state of deep mental concentration? Physical movement
+of some sort seems a necessary relief from mental effort. One man I
+know is always plucking at his watch chain when he is absorbed in some
+mental task. Another taps his desk with a pencil. My own favorite
+diversion on such occasions is to beat a tattoo with my knuckles.”
+
+“Highly interesting,” remarked Latham, “but I fail to see the point. It
+is either very shallow or very deep.”
+
+“Neither, Latham. A little while ago, while you were enacting that
+highly dramatic scene for Englebreth’s benefit, I stood back there in
+the corner, with my hands behind my back, tapping the wall with my
+knuckles. No one noticed me, for you held the attention of everybody
+in the room. I didn’t realize what I was doing myself until suddenly I
+became aware that my knuckles were producing a hollow sound.”
+
+Doctor Latham gasped. “You mean that——”
+
+“We shall see,” said Cole; and in an instant he was back in the corner,
+crouching low while his knuckles hammered the wall, each tap producing
+a dull, hollow sound. The doctor, visibly excited, stood behind him,
+watching every move he made. Cole continued the tapping until he had
+determined the boundaries of the hollow space, extending about five
+feet from the corner, and then he got down on his knees and ran his
+hands along the beveled joint between wall and floor. A little cry of
+elation escaped him as his fingers encountered a small protuberance.
+Almost instantly a portion of the wall turned back as if swinging on a
+central pivot. In front of them extended a long, dark hall.
+
+“Great!” exclaimed Latham, his voice shaking a little. “You deserve a
+harp and a halo, Cole. Now let’s make the hasty exit you spoke of.”
+
+He pressed forward, but Cole pulled him back. “I don’t want a harp
+and a halo just yet,” he declared, “and that’s why we are going to
+stay in this room a while longer. You forget that it’s still broad
+daylight outside. If we went out now, we would doubtless run into one
+of Englebreth’s sluggers. We must wait till dark.”
+
+Latham groaned as Cole closed the opening. He glanced at his watch.
+“Only half past three. That means a wait of several hours.”
+
+“I know. That will give us ample time to lay our plans. Don’t forget
+that we are both unarmed, and that we’ll cut a sorry figure if we
+should be caught. We don’t want to waste the only advantage we have.”
+
+“You are right, of course,” admitted the doctor. “What do you suggest?”
+
+Cole reflected. “It isn’t likely Englebreth knows anything about the
+hidden exit. If he did, he would have chosen a different cell for us.
+We’ll treat him to a little surprise after dark, Latham. Its exact
+nature will be determined by whatever developments come along in the
+meantime.”
+
+“Wish they would hurry,” mumbled the doctor, all impatience now that
+a way out had been found. He sat down, lighted a cigarette, and made
+ostentatious efforts to compose himself for a wait. An hour dragged
+by. The beam of light coming through the narrow rift in the shutter
+grew thin and pale. Another hour passed, and it disappeared altogether.
+Latham got up and began pacing the floor with long, lunging strides.
+For a long time not a word had been uttered between the two men.
+
+“Isn’t it about time to make a move?” asked Latham suddenly.
+
+Cole started. The subterranean pulsations, sounding clear and exultant
+in the stillness, had cast a spell over his senses. Now he looked at
+his watch in the light of the electric bulb overhead.
+
+“Better wait another hour,” he suggested.
+
+Doctor Latham swore under his breath, then lighted another cigarette.
+
+“Queer we haven’t heard from Englebreth,” Cole remarked. “I expected
+another call from him before dark.”
+
+“He is probably meditating over his next move. I imagine he is planning
+a very brilliant stroke. But we’ll checkmate him, eh, Cole?”
+
+Latham’s impatience was beginning to communicate itself to Cole. He
+took his watch from his pocket, and in the same instant a noise sounded
+outside the door. In a moment it opened, and two huskies, with leveled
+automatics, appeared in the room.
+
+“Miss Brownell wants you,” announced one of them, addressing Doctor
+Latham.
+
+The physician, evidently in a quandary, looked questioningly at Cole.
+For only a moment Cole hesitated. Doubtless the summons meant that
+Englebreth was trying a new mode of attack and that the reference to
+Miss Brownell was only a subterfuge.
+
+Cole nodded in response to the physician’s unspoken question. “If Miss
+Brownell wants you, you must go to her,” he declared, conscious that
+one of the guards was watching him intently. In an undertone he added:
+“If you get into a pinch, keep stalling till I show up.”
+
+Latham nodded and walked out, accompanied by the two gangsters. Cole
+watched him until the door closed behind him.
+
+“Wonder what Englebreth is up to this time,” he muttered; and then,
+moving quickly, he stepped into the corner and, opening the hidden
+door, stepped out into the dark hall beyond.
+
+
+
+
+ CHAPTER XXVIII
+
+ THE ENEMY STRIKES
+
+
+Silent as a shadow, Cole hurried down the hall, which seemed to extend
+endlessly in an undeviating direction. Believing it had once been used
+as an emergency exit he supposed it would eventually lead into the
+open. He had made no plans beyond the immediate present, but it was
+his intention to join Doctor Latham as soon as possible and, taking
+advantage of the sensation his unexpected appearance would create,
+make the most of his opportunity. Beyond doubt the physician was in
+desperate danger. The murderous glance Englebreth had thrown over his
+shoulder as he left them a few hours ago had left an ominous imprint on
+Cole’s mind.
+
+Soon he brought up against an obstruction, apparently a blank stretch
+of wall. He fumbled with his hands along the surface expecting to find
+a contrivance similar to the one at the other end of the wall. Soon
+his fingers encountered the little knob at the bottom which told him
+his surmise had been correct. Cautiously he pressed outward and the
+obstruction gave. A breath of cool night air fanned his face as he
+stepped out.
+
+Hugging close to the wall he looked about him. Evidently he was in the
+rear of the house, in a wide recess formed by two projecting wings.
+Above him and to the sides were several lighted windows, while ahead
+of him was a sloping, rock-strewn stretch of landscape. Carefully
+picking his way, he stepped along the nearest wall, all his senses
+on the alert against an interruption. He reached the corner, looked
+around the edge of the wall, and then drew back. A stalwart individual,
+evidently one of Englebreth’s lookouts, was coming toward him.
+
+Cole shrank back against the wall, waited until the man rounded the
+corner, then swung out with his right hand and landed a smashing blow
+on the fellow’s jaw. Without a sound the sentry dropped to the ground,
+and Cole dragged him into the shadows along the wall. It took him but a
+few moments to undo the man’s shoe laces and secure his hands and feet.
+Next he ripped out the lining from his coat, folded it into a narrow
+strip, and firmly applied it as a gag. Last of all he extracted an
+automatic from the unconscious man’s hip pocket.
+
+“I’m in luck so far,” he told himself, making certain that the weapon
+was loaded before he continued his interrupted progress. He breathed
+more easily now, for the possession of a firearm had a soothing effect
+on his nerves. He crawled forward along the wall, exercising infinite
+care, until he reached a window in the wing. It was dark, and no sound
+came from within, signifying that this part of the building was not
+used by the gang. He placed his elbow against the pane, pressing firmly
+until the glass cracked. Dislodging several of the splinters, he pushed
+a hand through the opening and released the catch. In a moment he was
+inside and began to pick his way cautiously across the floor. At the
+farther side he opened a door, traversed another dark and deserted
+room, then still another. Soon he found himself in a hall, and after
+a glance up and down its length selected a door at random. The moment
+he stepped inside voices reached his ears. Along the side, diagonally
+across the floor from where he stood, a narrow streak of light showed
+the location of the door.
+
+He tiptoed across the floor, placed his hand on the knob, turned it
+carefully, and opened the door an infinitesimal crack. In an instant
+he recognized the room. It was the office that had been the scene of
+his short-lived triumph the night before. Englebreth was seated at
+the desk, occupying the same wheel chair in which he had sat while
+witnessing Cole’s abortive ruse. The door before which Cole now stood
+was the one that had so abruptly opened while he was on the point of
+telephoning Carlin. He was vaguely aware that the scene had changed
+since last night, but he had no time to observe details. His attention
+was instantly engrossed by the little drama taking place before his
+eyes.
+
+On a cot placed along the farther side of the room lay Latham, and,
+save for an occasional turn of the head, he lay so still that Cole,
+although he could not see distinctly, guessed that he must be strapped
+to the cot. Over him, bending slightly, with a wicked smile playing
+about his bearded lips, stood Doctor Ballinger, and in his hand was a
+small object which Cole could not distinguish. The only other occupants
+of the room were Englebreth and two of the stalwart bodyguards who
+always seemed to be hovering about him.
+
+“Yes, it was clever, Latham,” the cripple was saying. “You played your
+cards just right. Whether you were serious or whether you were bluffing
+is beside the point. Your death would have been ill-timed from my point
+of view. I don’t think you are afraid to die, Latham. There is one
+thing you are afraid of, however.”
+
+He stopped. For several moments the room was very still. Ballinger,
+straightening his back, looked meditatively at the object in his hand,
+which, as Cole now perceived, was a small bottle.
+
+“That one thing is blindness, Latham,” added the cripple impressively.
+“Tell him, Ballinger.”
+
+Ballinger held the vial before the recumbent man’s eyes. “One small
+particle of this fluid dropped into each of your eyes will blind you
+for life,” he announced. “Not a pleasant thing to contemplate, eh,
+Latham?”
+
+Cole started as he saw the diabolical form of persuasion that was being
+employed by the conspirators to make Latham reveal what he was supposed
+to know. It was a threat far more hideous than death itself. He saw
+Latham’s chest heave upward as he strained against the fetters that
+held him to the cot.
+
+“What do you say, Latham?” asked the cripple, bending slightly out of
+his chair.
+
+“I’ll say that you and Ballinger are a pair of scurvy blackguards,” was
+the physician’s retort. “I take solemn oath that I will send each of
+you to jail with a black eye.”
+
+Ballinger laughed derisively.
+
+“Still stubborn, I see,” Englebreth remarked. “I am warning you for
+the last time, Latham. If you think Cole can come to your rescue, you
+are mistaken. Between you and me, that infernal meddler will never
+leave Dutchess Point alive. With you it is different. You can make
+yourself useful to us, and that is why I am offering you terms. But you
+must decide quickly.”
+
+“Go to blazes!” said Latham, but there was a catch in his voice,
+scarcely audible even to Cole’s keen ears, which told that his courage
+was faltering.
+
+“He thinks we are bluffing, Ballinger,” said Englebreth. “We must
+convince him that we are serious. Drop a little of the fluid into his
+left eye. The result will prove to him that we mean business.”
+
+A muffled groan came from the man on the cot. Ballinger stepped closer
+to the light, uncorked the little vial, cautiously inserted a small
+syringe through the neck, his brows contracting as he pumped the
+requisite amount of fluid into the glass tube. Now he set the bottle
+down, replaced the cork, and with the syringe in his hand turned again
+toward the man on the cot. A faint grin hovered about his bearded lips,
+but he had taken only a step in the direction of the cot when a sharp
+command rang out:
+
+“Stop, Ballinger!”
+
+As he spoke, Cole sprang forward and landed a vigorous blow with
+his automatic on the right hand of the guard standing nearest to
+Englebreth. A pistol dropped from the man’s limp fingers, and with an
+instantaneous movement Cole picked it up.
+
+Ballinger jerked up his head, then stopped dead in his tracks, facing
+the cot. The cripple whirled round in his swivel chair, a look of utter
+consternation flooding his white face as he saw Cole, standing calmly
+a foot away, a leveled automatic in each hand. The second guard leaped
+forward, but in a moment Cole had him covered.
+
+“Drop that gun!” he ordered, making an ominous gesture with one of his
+pistols. “This instant!”
+
+The man’s jaw sagged, and the weapon dropped from his hand. Englebreth,
+sitting hunched and shuddering in his chair, stared at the intruder as
+if he were seeing a specter.
+
+“You!” he exclaimed in a thin, rasping voice. “You——”
+
+Cole ignored him. His eyes gleamed like points of polished steel.
+“Ballinger,” he said in a very calm voice, “I’d rather put a bullet
+through your black heart, but I’m going to give you one chance for your
+life. See how quickly you can cut Doctor Latham loose. A little speed
+may save your life.”
+
+The syringe fell from Ballinger’s trembling fingers. For a moment he
+hesitated, then a knife appeared in his hand, and with surprising speed
+he slashed the cords around Latham’s hands and feet. A little dazedly
+the physician rose from the cot. There was a dull, smoldering fever in
+his eyes as he looked at Ballinger. With startling suddenness his right
+hand shot out, landing a vicious blow between Ballinger’s eyes.
+
+“There—I promised you that!” he exclaimed grittily. “And you!”
+
+Again his powerful fist darted out, and a splash of crimson spurted
+from the region of Englebreth’s nose. With a sigh of vast content he
+looked at Cole.
+
+“How in the world did you——”
+
+“Never mind,” Cole interrupted. “Get Carlin on the telephone.” As the
+physician started to obey, his cold, narrowing gaze swept each face in
+the room. “I’ll shoot the moment any one moves or makes a sound,” he
+declared.
+
+His voice had a ruthless ring, and no one moved. Englebreth, breathing
+raspingly, was wiping the blood from his face while he squinted at Cole
+in a dazed way.
+
+The physician hung up the receiver and stepped away from the telephone.
+
+“I got Carlin out of bed,” he reported. “He will be here in a little
+while, and he will bring enough men with him to surround the place.
+These human hyenas will soon be where they belong.” He looked about
+him with a satisfied expression. “I hope Carlin won’t treat the speed
+regulations too tenderly. I’m hungry as the deuce.”
+
+“So am I,” admitted Cole, a trifle absently. The throbbing and pulsing
+of machinery sounded remotely in his ears, a muffled hymn of greed
+and gold-maddened dreams, soon to be silenced forever. He shrugged,
+and a look of fretful responsibility came into his face. “And there
+is Toots,” he went on. “I’ve been neglecting Toots lately. Latham,
+I’m going to give you a piece of advice, with the compliments of The
+Unknown Seven. Keep shy of cats.”
+

+<div class="subheadc">THE WOMAN IN THE LIMOUSINE</div>
+</div>
+
+<p class="drop-cap">STANDING in the dark doorway of a delicatessen shop, Kingdon Cole
+gazed, through the fog and drizzle of the October night, at a
+second-story window across the street. The brim of a slouch hat
+shaded his eyes and most of his face. His lean figure was draped in a
+mackintosh that reached almost to his feet. The upward slant of the
+cigar, clamped between his teeth, hinted at total absorption in what he
+saw.</p>
+
+<p>The building that claimed his attention was an ordinary three-story
+structure of murky brick. Flanked by a warehouse on one side and a
+secondhand clothing store on the other, it presented a sullen and
+gloomy aspect to the watcher across the street. Yet there was something
+in the very drabness of the house and the chill atmosphere which hung
+over it that might have appealed to the imagination of a man like
+Kingdon Cole.</p>
+
+<p>A man’s head and shoulders were dimly silhouetted against the lighted
+window shade at which he was looking so fixedly. For half an hour or
+longer the figure had not stirred. The rigid poise of the head and the
+stiff set of the shoulders suggested that the man at the window was
+engaged in a task that occupied his whole mind.</p>
+
+<p>Cole struck a match and, holding it in his cupped <span class="pagenum" id="Page_10">10</span>hands, lighted his
+dead cigar. The flickering light shone for an instant on fingers that
+were long, slim, and finely tapering, the fingers of a man of great
+mental energy and a compelling personality.</p>
+
+<p>“Wonder what the learned Professor Carmody finds so interesting,” he
+mumbled. “Some scientific treatise, very likely, or perhaps it is——”</p>
+
+<p>He lowered his gaze, as he vaguely sensed that a pair of eyes was
+trying to pierce the gloom in which he stood. What with the wet night
+and the lateness of the hour that dreary section of Bleecker Street
+was all but deserted. Now and then a crosstown car jogged along at a
+lumbering pace; occasionally a taxicab passed on its way.</p>
+
+<p>Cole looked up and down the block. The impression was more distinct
+now. Some one was watching him, just as he was watching the solitary
+figure in the window. His senses, sharpened by long training, told him
+he was under observation even before he could trace the impression to
+its source. Now he saw a limousine drawn up at the corner, less than
+twenty paces from where he stood. Its sides of burnt sienna gleamed
+in the blurred lights. It seemed to lend a touch of affluence to the
+squalor and dreariness of the scene. How long the car had been there
+he did not know, for the window across the street had claimed all his
+attention.</p>
+
+<p>The car began to move, crawling, snaillike and silent toward the point
+where Cole stood. It stopped opposite the doorway that sheltered him.
+He fancied that he saw the flicker of a face behind the curtains. Then
+the door opened a few inches, and he caught a glimpse of a beckoning
+hand.</p>
+
+<p><span class="pagenum" id="Page_11">11</span></p>
+
+<p>His eyes narrowed under their puckering brows. The monotony of his
+vigil was being broken in a strange way, and the slow twisting of his
+lips signified that the interruption was not altogether displeasing.
+Once more he glanced up at the window across the street, noticing that
+the shadowy figure had not stirred. Then he crossed the sidewalk, and
+instantly the door of the limousine was flung wide.</p>
+
+<p>“Won’t you step in, Mr. Cole?” asked a voice.</p>
+
+<p>Though his life had inured him to surprises, Cole started a little. It
+was odd that the occupant of the car should address him by name. The
+interior was dark, but in the shadows he saw the figure of a woman.</p>
+
+<p>“You are very patient, Mr. Cole,” the voice continued. “You are wasting
+your time, however. It isn’t likely that Professor Carmody will go out
+to-night, so you might as well jump in.”</p>
+
+<p>A sharp hunching of Cole’s shoulders registered surprise number two. It
+was all very mystifying. Not only did the occupant of the car know his
+name, but she seemed familiar with his business as well. He liked her
+voice, a deep soprano with a faintly playful undertone. For a moment he
+studied the long, slender lines of her figure, faintly discernible in
+the dusk and melting, here and there, into a background of saffron-hued
+cushions.</p>
+
+<p>“You hesitate? I happen to know that Professor Carmody is in for the
+night and that your vigilance is useless.”</p>
+
+<p>Cole looked at her intently. The mist, the drizzle, and the blurred
+sheen from the street lamps seemed <span class="pagenum" id="Page_12">12</span>to lend a touch of unreality to
+what he saw and heard.</p>
+
+<p>“What do you know about Professor Carmody,” he demanded.</p>
+
+<p>“A great deal more than you do. It’s quite possible that I am in a
+position to give you some valuable information. At any rate my car is
+more comfortable than a dark doorway.”</p>
+
+<p>She leaned forward slightly, and there was a trace of mockery on her
+faintly parted lips. “Not afraid, are you, Mr. Cole?”</p>
+
+<p>He gave a low laugh at the implied dare. With a shrug he stepped inside
+the car and sat down beside her. She picked up the speaking tube and,
+turning her head away from Cole, said something which he could not
+hear. In an instant the car was in motion.</p>
+
+<p>“You seem to know a great deal,” he observed, trying to obtain a
+glimpse of her face under the billowing brim that shaded it.</p>
+
+<p>“And you are anxious to learn how much more I know. Isn’t it so, Mr.
+Cole? It was neither vulgar curiosity nor adventurousness that prompted
+you to accept my invitation to ride with me. You accepted only because
+you hoped to learn something. Having heard me speak your name and
+mention Professor Carmody you naturally thought it might be profitable
+to cultivate my acquaintance.”</p>
+
+<p>“Perhaps so,” said Cole dryly. “What do you know about me aside from my
+name and my interest in the estimable professor?”</p>
+
+<p>“A great deal,” was the surprisingly prompt reply. “You are a student
+of criminology, a follower in the <span class="pagenum" id="Page_13">13</span>footsteps of Lombroso, Pinel, and
+Prichard, though you by no means accept their theories. You have
+written two books on crime and criminals. They are too scientific for
+the general reader, I have been told, but experts on the subject regard
+them as authoritative. Perhaps some day I shall try to read them.”</p>
+
+<p>“I fear you won’t find them very interesting,” replied Cole. “What
+else?”</p>
+
+<p>“You live in a small apartment in Gramercy Park, which also serves as
+your office. Two years ago you did a very brilliant piece of work on
+the Wilmerding murder case, though you magnanimously, or for reasons of
+your own, let the police claim the credit for the results. You follow
+criminal investigations largely as a scientific pursuit. If you cared
+to devote all your time to it you could make a great success, but you
+accept only such cases as happen to interest you personally. As a
+result you lead a quiet and somewhat precarious existence, deriving
+your sole pleasure from your work and such inexpensive amusements as
+books, music, and, on rare occasions, the theater.”</p>
+
+<p>“You seem to have taken considerable pains looking me up,” he remarked.</p>
+
+<p>“Oh, I haven’t told you all I know yet. I have learned a number of
+things about your private life and personal habits, but we needn’t go
+into those things now.”</p>
+
+<p>“Are you equally well informed in regard to Professor Carmody?”</p>
+
+<p>“Not quite. The professor is a riddle. To all outward appearances he is
+interested in nothing but <span class="pagenum" id="Page_14">14</span>his experiments and his musty old books. He
+seems to be living in that kind of neighborhood by preference, because
+he isn’t so apt to be bothered by meddling neighbors. His house is said
+to contain one of the best-equipped laboratories of its kind in the
+world. That’s only a rumor, of course. The professor doesn’t encourage
+visitors. To the few people who have talked with him he is what the
+novelists call a man of mystery. He comes and goes without speaking
+to any one, and his life is a closed book. As far as I know, only one
+person has been inside his house in a year, and that person never came
+out.”</p>
+
+<p>“Oh, you know that!”</p>
+
+<p>“Yes, I am one of the very few who are aware of the fact. Let me see,
+it’s about three weeks since Malcolm Reeves disappeared. His relatives,
+your clients, in other words, have reason to believe that he visited
+Professor Carmody on the night of his disappearance. No wonder the
+case fascinates you, Mr. Cole. Disappearances are always interesting,
+but especially so when a mysterious person like Professor Carmody is
+involved.”</p>
+
+<p>Cole regarded her in frank amazement, but her head was now slightly
+bowed, and all he could see of her face was the curve of the chin.</p>
+
+<p>“The relatives did well to put the case in your hands,” she went on.
+“You are both capable and discreet and, as I presume you know, there
+were excellent reasons for not reporting Reeves’ disappearance to the
+police. Are you making satisfactory progress?”</p>
+
+<p>“My clients seem satisfied.”</p>
+
+<p><span class="pagenum" id="Page_15">15</span></p>
+
+<p>“You have not yet paid the professor a visit?”</p>
+
+<p>“What would be the use?”</p>
+
+<p>“You are right, of course. It would only put him on his guard. You
+prefer not to let him know that he is under suspicion.” She laughed
+gently, as if amused at something. “Besides, it is doubtful whether a
+search of Carmody’s house would reveal any clews to Reeves’ fate. The
+professor is a chemist, and I understand there are certain chemical
+processes by which bodies can be made to disappear completely, leaving
+no trace.”</p>
+
+<p>“Then you think Reeves has been murdered?”</p>
+
+<p>“Don’t you?” she asked quickly.</p>
+
+<p>Cole smiled. Instead of answering the question he asked another. “How
+can you be so sure that Carmody will not leave his house to-night?”</p>
+
+<p>“Because he has the best of reasons for staying in.”</p>
+
+<p>“What are they?”</p>
+
+<p>“One is that his engagement for to-night was canceled by telephone at
+four o’clock this afternoon.”</p>
+
+<p>Cole gave her a puzzled stare. “How do you know that?”</p>
+
+<p>She laughed a little. “There are ways of finding out,” she said
+mysteriously. “Tapped wires, for instance. But the professor’s
+principal reason for staying in to-night is that he is well aware that
+you are watching him. You see, Mr. Cole, he has more shrewdness than
+you have been giving him credit for. And the fact that he is staying in
+on your account shows that he has great respect for your ability.”</p>
+
+<p><span class="pagenum" id="Page_16">16</span></p>
+
+<p>She had raised her head a trifle, and Cole gave her a long, bewildered
+glance. He half expected to see a smile on her lips, but her face was
+grave.</p>
+
+<p>“Are you one of Reeves’ relatives?” he asked abruptly.</p>
+
+<p>“Oh, no!”</p>
+
+<p>“Then how——”</p>
+
+<p>“I have certain sources of information. Sources so vast that you would
+be staggered if I were to tell you of them. Please don’t look at me
+like that. I am not insane, neither am I subject to hallucinations. The
+fact that I happen to know more about the Carmody case than you do is
+no reflection on your ability as an investigator. It merely shows that
+your equipment is inadequate. Care to hear more?”</p>
+
+<p>“What else do you know?”</p>
+
+<p>“I know that the case you are working on is only one minor angle of a
+vast mystery. The disappearance of Malcolm Reeves is nothing but an
+incident. Reeves himself was only an insignificant puppet in one of
+the greatest games ever played. All you have seen so far is one of the
+minor threads in the woof. I am always mixing my metaphors, but I know
+you won’t mind. Mr. Cole, this affair has ramifications that may some
+day rock the whole continent.”</p>
+
+<p>“I feel considerably shaken up already,” admitted Cole. “You realize,
+of course, that you are using strong words?”</p>
+
+<p>“No stronger than the situation demands.”</p>
+
+<p><span class="pagenum" id="Page_17">17</span></p>
+
+<p>“If it is as bad as all that why doesn’t somebody put a stop to it?”</p>
+
+<p>“Because——” She checked herself and regarded him intently. “Well,
+because the man who is big enough for the task has not yet been found.”</p>
+
+<p>Again Cole cast a glance at the window. The car had made several
+turns in the last few minutes. He caught only a blurred view of his
+surroundings, but he thought they were traversing one of the cavernlike
+streets near the southern tip of Manhattan Island.</p>
+
+<p>“Have you heard enough?” she asked.</p>
+
+<p>“Just enough to give me an appetite for more.”</p>
+
+<p>“In that case you must trust me implicitly and obey me without
+questions. I am taking desperate chances in confiding in you, Mr. Cole,
+and certain precautions are absolutely necessary. Will you promise me
+on your honor that you will not try to ascertain the location of the
+place I shall take you to?”</p>
+
+<p>Cole considered. There was a flavor of mystery about the adventure that
+appealed to him, but the prospect of learning something more about the
+Carmody case was an even greater temptation. From what little the woman
+had so far told him he surmised that she must have unusual sources of
+information. Much that she had said coincided with what he already
+knew, so he had no cause to doubt her truthfulness.</p>
+
+<p>“You have my promise,” he told her.</p>
+
+<p>The car made another turn, swung down a dark block, then veered again
+to the south. Cole caught a hazy glimpse of dark, towering skyscrapers.</p>
+
+<p><span class="pagenum" id="Page_18">18</span></p>
+
+<p>The woman looked at him fixedly, as if in doubt. “I believe you are a
+man of your word, Mr. Cole, but promises are sometimes broken in spite
+of the best intentions. Please don’t be offended.”</p>
+
+<p>She produced a scarf and with a deft touch covered his eyes, securing
+the bandage with a firm knot at the back. Cole chuckled amusedly. He
+might be walking into a trap, but it would not be the first time, and
+he had great confidence in his ability to take care of himself in any
+situation that might come up.</p>
+
+<p>After continuing its zigzagging course a few minutes longer the car
+stopped. His mysterious conductress touched his arm as they stepped
+out. She guided him across the sidewalk and up a few stone steps, and
+then they traversed what appeared to be a long corridor. Finally Cole
+found himself in a narrow inclosure which he guessed to be an elevator.</p>
+
+<p>“We are in one of the tallest office buildings in New York,” the woman
+whispered in his ear, “but you’re not likely to guess its name.”</p>
+
+<p>The door clanked shut, and the cage shot swiftly upward. Cole felt
+a rush of wind in his ears. He maintained a languid composure, but
+inwardly he marveled. A modern skyscraper was the last place he would
+have expected the woman to take him to. He tried to estimate the number
+of floors they were passing. Five, ten, fifteen, twenty——</p>
+
+<p>Still the cage darted upward, and then it stopped so suddenly that
+he caught his breath sharply. They stepped out, and the girl removed
+the scarf from his eyes. He gazed around him bewilderedly. All about
+him, with the exception of a single elevator <span class="pagenum" id="Page_19">19</span>shaft was a vast expanse
+of blank wall. There was no sign of doors or windows, and the only
+illumination was a small electric bulb in the ceiling.</p>
+
+<p>“We came up in a private elevator,” the woman explained. “This is the
+top floor. To the public at large and to most of the tenants of the
+building it practically does not exist. This way, Mr. Cole.”</p>
+
+<p>She stepped to one of the corners of the triangular space, of which the
+elevator shaft formed the center, and Cole followed. In the dim light
+he could not see exactly what happened, but the woman’s hand went out
+and then a narrow portion of the wall slid back. They stepped through
+an aperture, and instantly the opening closed behind them. They were in
+a long corridor with doors on each side.</p>
+
+<p>“Surprised?” she asked, starting to lead him down the hall.</p>
+
+<p>“Rather. Never expected to find such mysterious contrivances in a
+modern office building.”</p>
+
+<p>Her only reply was a low laugh. The floor of the corridor was
+luxuriously carpeted; the doors on either side had a solid appearance.
+Cole’s amazement grew. He wondered what was beyond the massive doors
+and what was the nature of this establishment that was hidden behind
+blank walls. He had little time for speculation, for his companion
+opened a door and bade him enter.</p>
+
+<p>“Excuse me, Mr. Cole,” she murmured when she had switched on the light.
+“I shall be back directly.”</p>
+
+<p>The door closed, and she was gone. Alone, Cole looked about him, and
+his eyes opened wide in astonishment.</p>
+
+<hr class="chap x-ebookmaker-drop">
+<div class="chapter">
+<span class="pagenum" id="Page_20">20</span>
+<h2 id="chap_II">CHAPTER II</h2>
+<div class="subheadc">TEMPTATION</div>
+</div>
+
+<p class="drop-cap">FOR a moment Cole forgot that he was in a building devoted to the
+pursuits of commerce. The room in which he stood, bordered by walls of
+paneled walnut, was worthy of a Fifth Avenue mansion. It struck him as
+a bit grotesque. From an elevator he had stepped, through a blank wall,
+into a magnificence that fairly dazzled him. It was like an “Arabian
+Nights” adventure. As he looked about him he saw quiet elegance
+everywhere, without a taint of showiness. For some time he stood lost
+in admiration, then he noticed that the room had no windows. A moment
+later he discovered that the door was locked on the outside. Despite
+the splendor that surrounded him he was virtually a prisoner.</p>
+
+<p>He sat down and smoked a cigarette, waiting for his strange conductress
+to return. Evidently the walls were solidly built, for no sounds
+reached him. The air was fresh and pure despite the absence of windows,
+hinting that there was a concealed ventilator somewhere in the room.</p>
+
+<p>The armchair was comfortable, and he stretched out his lean figure,
+slightly short of six feet. The man suggested mental force rather
+than bodily strength, but a great surprise awaited any antagonist who
+underestimated Cole’s physical prowess. He was far stronger than the
+average man, and his <span class="pagenum" id="Page_21">21</span>endurance was phenomenal. His gray eyes, with a
+faint humorous twinkle in their depths, were fixed on the door. His
+dark face, slightly lined about the mouth and the outer corner of the
+eyes, bore a look of mild expectancy. In moments of repose he looked as
+though he had not a care in the world. His friends often wondered how
+he managed to maintain the freshness and sparkle suggestive of a recent
+needle shower. Perhaps it was because he was thoroughly in love with
+his work and had learned to shake off the minor frets and irritations
+of life.</p>
+
+<p>In the midst of his musings the door opened, and he stared rather
+rudely at the vision that entered. It was the woman, and she had
+undergone an amazing transformation since he last saw her. He wondered
+whether the shimmering gown she wore had been designed by Poiret
+himself. Its delicate rose color afforded a charming contrast to her
+complexion, a sort of luminous white that somehow escaped being pale.
+Standing there, with a faint smile on her lips, her face fringed by an
+aureole of fine-spun gold, she was easily the most bewitching woman
+Cole had ever seen.</p>
+
+<p>He rose, bowed, and gazed appreciatively at the simple, but strikingly
+effective, ornament she wore at her throat.</p>
+
+<p>“Sorry to have kept you waiting,” she murmured. “Sit down, please, and
+smoke as much as you like. I want to talk with you.”</p>
+
+<p>Cole sat down. He wondered if she had arrayed herself like this for the
+sole purpose of having a talk with him.</p>
+
+<p><span class="pagenum" id="Page_22">22</span></p>
+
+<p>“You promised to tell me something more about the Carmody case,” he
+reminded her. “I suppose you brought me to this charming place so
+that we might have a quiet talk without danger of interruption or
+eavesdropping.”</p>
+
+<p>She sat down a short distance from him. By degrees the smile faded from
+her lips. A curiously solemn expression crept into her face. “Haven’t I
+told you enough, Mr. Cole?”</p>
+
+<p>“What little you told me was only a provocation. It gave me a taste for
+more. By the way, you have the advantage over me. Won’t you tell me
+your name?”</p>
+
+<p>“You may call me Miss Brown.”</p>
+
+<p>“The name doesn’t fit you,” he objected.</p>
+
+<p>“Names never do fit. That’s one of the ironies of existence. For the
+present, until we know each other better, it will have to be Miss
+Brown. I had to tell you a little about the Carmody case in order to
+get your attention. I hope I convinced you that it is quite useless
+for you to continue at work on a case that is so enormous in scope and
+presents such insuperable difficulties, Mr. Cole.” A pleading note had
+come into her voice. “Can anything persuade you to drop the Carmody
+case?”</p>
+
+<p>She bent forward a little. With hands clasped across her knee, she
+studied him intently, and Cole looked into the deepest, bluest eyes he
+had ever seen.</p>
+
+<p>“Drop the Carmody case!” he exclaimed.</p>
+
+<p>“You must drop it, Mr. Cole! If you knew more about it, what terrible
+things you are going up against, you would willingly drop it without
+<span class="pagenum" id="Page_23">23</span>further argument. You would recognize your utter helplessness in the
+matter, not to mention a number of other things.”</p>
+
+<p>Cole was momentarily speechless. He found himself strangely impressed
+by her big, sorcerous eyes, full of mute pleading and entreaty.</p>
+
+<p>“I don’t understand. You don’t realize what you are saying. Why should
+I drop the case?”</p>
+
+<p>“Because of the things I have told you.”</p>
+
+<p>Cole laughed. “They are only an added incentive for me to go on with
+it.”</p>
+
+<p>She drew a long breath. “That’s your man’s way of looking at things.
+The greater the dangers and difficulties the more determined you are
+to forge ahead. You don’t stop to consider the price, or estimate the
+cost. The wreckage you scatter about you means nothing to you. All you
+think of is the gratification of your boundless ambition. Mr. Cole,
+won’t you forgo your foolish pride and do what I ask?”</p>
+
+<p>Her eyes held him despite his will. There was a look of terror in
+their depths that exerted a subtle appeal upon him. He got to his feet
+and tried to shake off the fascination of her beauty and her magnetic
+personality.</p>
+
+<p>“Impossible,” he declared. “If you brought me here in the hope of
+inducing me to drop the Carmody case, your time and effort are wasted.”</p>
+
+<p>“Please, Mr. Cole! Forget that you ever heard of this terrible case.
+Tell your clients in the morning that you will have nothing further to
+do with it.”</p>
+
+<p>“That wouldn’t alter matters. They would <span class="pagenum" id="Page_24">24</span>promptly accept my
+resignation and engage somebody else.”</p>
+
+<p>“There is only one Kingdon Cole.”</p>
+
+<p>“That’s a very neat compliment, but it won’t bear analysis. I haven’t
+accomplished anything very wonderful, and another man could finish what
+I have begun.”</p>
+
+<p>She was silent for a time, her big, luminous eyes regarding him
+imploringly. “If you won’t drop the case for your own sake, because of
+the terrible dangers involved, then I beg you to do so for my sake.”</p>
+
+<p>“For your sake? Really, Miss—er—Brown, I don’t understand. What is your
+interest in the Carmody case?”</p>
+
+<p>She stepped up and clutched his hand. The touch of her fingers sent
+a thrill through him. Her eyes were moist, and the curve beneath her
+throat rose and fell with accelerated rhythm. “Yes, for my sake. I
+can’t explain, except to say that awful things will happen to me if you
+go on. Death would be as nothing in comparison. Doesn’t a woman’s soul
+mean anything to you, Mr. Cole?”</p>
+
+<p>Cole looked down into her eyes, while her fingers spasmodically
+clutched his hand. Far into their blue depths he gazed, and suddenly
+his face underwent a change. His lips curled a trifle, and a hard glint
+came into his eyes. Somewhat roughly he released his hand.</p>
+
+<p>“Very touching,” he dryly remarked, “but I don’t see the connection
+between the Carmody case and a woman’s soul.”</p>
+
+<p>She drew back with a little sob of bafflement.</p>
+
+<p><span class="pagenum" id="Page_25">25</span></p>
+
+<p>“If you meant your own soul, Miss Brown, you mentioned something that
+doesn’t exist,” he went on sarcastically. “Trickery and pretense are
+poor substitutes for soul.”</p>
+
+<p>“What do you mean?”</p>
+
+<p>He shrugged disgustedly. “Your acting is superb, but it don’t bear
+close inspection. You were splendid at a little distance. Despite the
+fact that I am the only Kingdon Cole, as you so charmingly phrased it,
+I am rather susceptible to the tears of a beautiful woman. With your
+sobs and your loveliness you could have melted a stone, if such a feat
+were possible. As soon as I got a close view of you, however, I knew
+you were only shamming. Your eyes gave you away when you sprung that
+choice line about a woman’s soul. Perhaps you realized you were laying
+the pathos on too thick. Anyway the illusion is shattered, and all that
+remains is the gorgeous gown you are wearing. It is really stunning.”</p>
+
+<p>“Thank you,” she said coldly, dropping the rôle she had been playing,
+as easily as she would a wrap. “No doubt I should have known better
+than to try such methods on you.”</p>
+
+<p>“Yes, you should,” said Cole. “For, despite the little slip you made,
+I believe that you are really a very clever woman. Now that we are off
+the subject of women’s souls won’t you tell me your real reason for
+wishing to throw up the Carmody case?”</p>
+
+<p>She shook her head, but he thought he detected a gleam of unwilling
+admiration in her eyes. Motioning him to follow, she stepped to the
+door and <span class="pagenum" id="Page_26">26</span>opened it, then preceded him down the hall. Cole guessed that
+his little adventure was over, and he felt a twinge of disappointment
+at the thought that, in all probability, he would never learn the
+meaning of her puzzling behavior. No doubt she would try to blindfold
+him again before conducting him away from the place, and he was
+prepared to raise strenuous objections.</p>
+
+<p>But it appeared Miss Brown was not yet ready to let him go. She stopped
+before one of the massive doors that had already excited his curiosity,
+and knocked twice. It opened quickly and noiselessly. In a moment,
+before he realized what he was doing, Cole was inside, and the door
+closed at his back.</p>
+
+<p>The room was so dimly lighted that at first he could distinguish
+nothing but bare, gloomy walls. Miss Brown, who had followed him into
+the room, hastened forward and seemed to melt away in the dusk, leaving
+him to wonder what new turn his adventure was taking. Gradually, as his
+eyes grew accustomed to the gloom, he was able to see objects with some
+degree of clearness. He was in a long, narrow room, and what he saw
+was in keeping with the other strange things that he had witnessed and
+experienced in this surprising establishment.</p>
+
+<p>A number of shadowy figures were seated around a circular table in
+the center of the room. He counted seven of them, and at first he had
+a ludicrous impression that there were only blank spaces where their
+faces should have been. Then, as his pupils continued to respond to the
+strain imposed <span class="pagenum" id="Page_27">27</span>by the dim light, he saw that each man wore a mask.
+It was only a strip of cloth, with tiny slits over the eyes, but in
+the dusk it was the only covering that was needed to make recognition
+impossible.</p>
+
+<p>Again Cole was struck with a sense of unreality. The men, sitting
+stiffly erect in their chairs, caused him to wonder whether he was in
+the midst of some ghostly séance. He felt their eyes searching him
+through the vents in the masks. The gloom and the silence gave an added
+illusory touch to the scene. Cole had to shake himself before he could
+realize that he was on the top floor of a modern skyscraper.</p>
+
+<p>Miss Brown stepped behind one of the chairs and held a brief whispered
+conversation with its occupant. The latter nodded, and the girl
+slipped away toward the door. A moment later it closed behind her, and
+the man, with whom she had been talking, indicated that Cole was to
+step forward. With a shrug he complied, and the masked faces stirred
+slightly as he approached. For a full minute nothing was said, and
+again he felt the sharp and steady scrutiny of seven pairs of eyes.
+Finally the man who had beckoned him spoke. “Mr. Cole, how much will
+you take to drop the Carmody case?”</p>
+
+<p>Cole could not help but laugh. The words, spoken with a directness
+and a matter-of-factness that left nothing to the imagination, had
+shattered the illusion completely. In an instant the spell of unreality
+was broken. He knew he was dealing with practical men who were in the
+habit of reducing everything to terms of dollars and cents. A blunt
+reply came <span class="pagenum" id="Page_28">28</span>to his lips, but his desire to learn more of these strange
+men caused him to hold it back.</p>
+
+<p>“Suppose we put all the cards on the table,” he suggested. “I don’t
+like to talk business in the dark. Who are you, and what is your
+objection to my connection with the Carmody case?”</p>
+
+<p>“We are not here to answer questions,” declared the one who seemed to
+be acting as spokesman for the others. “All I care to say is that,
+because of a peculiar combination of circumstances, it is to our
+advantage to pay you liberally for withdrawing from the case. What’s
+your price, Mr. Cole?”</p>
+
+<p>Under ordinary circumstances, Cole would have been indignant at this
+cool assumption that every man has his price, but now his dominant
+emotion was curiosity. He could not understand why they seemed so
+intent upon persuading him to sever his connection with the affair, but
+what Miss Brown had said about the vast ramifications of the Carmody
+case suggested that they had ample reasons for what they were doing.</p>
+
+<p>“Let me get this straight,” he said evenly. “You are willing to pay me
+my price for withdrawing from the Carmody case. Are there any strings
+to the proposition?”</p>
+
+<p>The other chuckled dryly. “I wouldn’t call them strings, exactly. They
+are only gossamer threads. In addition to retiring from the case you
+are to give us a full and veracious report of what you have discovered
+to date in connection with the disappearance of Malcolm Reeves.”</p>
+
+<p>“I see,” said Cole. “Anything else?”</p>
+
+<p>“Just one thing more. In addition to withdrawing <span class="pagenum" id="Page_29">29</span>from your present
+connection with the case and turning the information you possess over
+to us, you are to come over to our side and put your ability at our
+disposal. We are ready to pay you handsomely for your services, either
+on a contingent basis, or in the form of a weekly salary.”</p>
+
+<p>“Very generous,” declared Cole, with a faint trace of sarcasm. “Your
+proposition is that, for a consideration, I am to betray my present
+clients and——”</p>
+
+<p>“Betray is a harsh word,” objected the spokesman for the group.</p>
+
+<p>“Truthful terms are usually harsh,” Cole remarked. “Let’s not quibble
+over words. In addition to the amount, which you are willing to pay me
+for betraying my clients, you offer to reward me liberally for certain
+services that you require. May I ask what they are?”</p>
+
+<p>“You will learn soon enough if you accept our proposition. Let me state
+that we have unlimited funds at our disposal and stand ready to pay
+you well. It would be no exaggeration to say that in a short time you
+should be a rich man if you accept our offer. In view of our liberality
+don’t you think it behooves you to be less squeamish and ask fewer
+questions?”</p>
+
+<p>“I suppose it is in deucedly bad taste for me to argue with a man who
+offers me a fortune on a silver platter,” Cole admitted. “Just the same
+I can’t help wondering why you are offering such a glittering bribe to
+one who is practically unknown in his profession.”</p>
+
+<p>The man gave an amused chuckle. “Don’t worry <span class="pagenum" id="Page_30">30</span>about that, Mr. Cole.
+We are not in the habit of buying pigs in a poke. You have been under
+observation for some time.”</p>
+
+<p>“So I gathered from what the bewitching Miss—Brown told me.”</p>
+
+<p>“We have learned that you have a great deal of ability. You are
+fearless and persevering. You have qualities that the average
+professional detective sadly lacks, such as tact, polish, and a
+magnetic personality. In short, you are precisely the kind of man
+we need. We have reason to believe that you have discovered certain
+interesting facts in connection with Malcolm Reeves’ disappearance,
+facts which would naturally become our property if you came over to our
+side.”</p>
+
+<p>Cole marveled at the extent of the man’s knowledge. It was true that he
+had picked up several stray facts which, when considered in conjunction
+with the known circumstances of Reeves’ disappearance, made a fairly
+interesting showing. His glance wandered over the circle of veiled
+faces. Each of the seven men was watching him intently through the
+slits in his mask.</p>
+
+<p>“We are waiting for your decision, Mr. Cole,” remarked the spokesman
+after a pause. “If our proposition appeals to you, name your price.”</p>
+
+<p>Cole pretended to hesitate. He hoped to learn a little more before he
+closed the interview. He wondered how far these men would go in their
+efforts to induce him to betray his clients and transfer his allegiance
+to themselves. “Aren’t you forgetting something?” he asked. “Do you
+realize <span class="pagenum" id="Page_31">31</span>that a man who has been bought once will probably sell himself
+again?”</p>
+
+<p>Though he could not see, he fancied the spokesman’s eyes were twinkling
+behind the mask.</p>
+
+<p>“We have considered everything, Mr. Cole. You wouldn’t sell yourself
+except to a higher bidder, and it isn’t likely any one will outbid us.
+If such a situation should arise, however, we would know how to handle
+it. What is your price?”</p>
+
+<p>“Suppose you name the price you are willing to pay?”</p>
+
+<p>There was a craning of necks, and nods and subdued whispers passed
+around the circle. Evidently the seven construed his words as meaning
+that he was yielding. The spokesman unlocked a drawer in front of him
+and placed a small package on the table.</p>
+
+<p>“Twenty-five thousand dollars,” he remarked impressively. “If you are
+in doubt as to the amount, or if you suspect that I am handing you
+stage money, you will be permitted to examine it in the light.”</p>
+
+<p>He handed the package to Cole. “Remember that this is only your
+retaining fee, so to speak. There will be lots more coming to you if
+you decide to throw in your lot with us.”</p>
+
+<p>Cole felt the crisp fiber of the bills. He did not doubt that the money
+was genuine or that the package contained the exact amount mentioned
+by the spokesman. Whatever else these men might do, he did not think
+they would stoop to petty cheating. An odd sensation surged through him
+as he weighed the currency in the palm of his hand. It was more <span class="pagenum" id="Page_32">32</span>money
+than had ever before come within his reach. Of a sudden he remembered
+some of the things he had been compelled to deny himself because of
+his slender and uncertain income. Until this moment, when he held the
+wherewithal in his hand, it had not occurred to him that he was missing
+any of the good things in life. He had accepted his privations, as a
+matter of course, with a smile or a shrug, according to his mood of the
+moment.</p>
+
+<p>For a few seconds longer he gave himself over to thrill of possession,
+and then he tossed the bundle of currency down on the table. “It isn’t
+enough,” he declared.</p>
+
+<p>A chorus of murmurs went around the circular table. The veiled faces
+strained forward a little. Once again Cole fancied the spokesman’s eyes
+were twinkling through the orifices in the mask.</p>
+
+<p>“Splendid, Mr. Cole,” said the man approvingly. “I didn’t think
+twenty-five thousand would satisfy you, but I wanted to make sure. As a
+matter of fact, if you had accepted such a paltry amount, we would have
+broken off the negotiations instantly. We don’t want a man who holds
+himself cheap. Here”—again he opened the drawer in front of him—“is
+another twenty-five thousand. That makes fifty. Quite a neat sum for a
+man whose income last year was only a trifle over four thousand.”</p>
+
+<p>“How did you know that?”</p>
+
+<p>“Income-tax reports,” said the man.</p>
+
+<p>Cole took one bundle of currency in each hand. He was no longer
+marveling at the surprising sources of information that seemed to be
+open to these men. For the moment all his senses were <span class="pagenum" id="Page_33">33</span>centered on the
+wealth that lay in his palms. A flash of self-revelation came to him,
+and he was surprised and frightened by it. He had never known that mere
+money could give him such a delectable sensation. In the past, as a
+passive onlooker, he had smiled tolerantly at other men’s scramble for
+wealth. With philosophic eyes he had watched the money-mad procession
+sweep by him. Now he found that the sheer touch of the currency sent a
+contagion through his veins, awakening strange emotions within him.</p>
+
+<p>The sensation put an indefinable fear into him, fear of himself and
+the weakness he had just discovered. Of a sudden the currency seemed
+to scorch his palms. He shrugged, and the spell was broken. With an
+inward paroxysm he flung the money down on the table. “Not even that is
+enough,” he announced in slightly dazed tones, like one just awakening
+from a dream.</p>
+
+<p>The spokesman’s head came up a little. With a shrug and an indistinct
+mutter he once more opened the drawer, but Cole laid a detaining hand
+on his sleeve.</p>
+
+<p>“Wait!” he said quietly. “You are going ahead on the idea that every
+man has his price. You’re mistaken. There isn’t money enough in the
+whole United States treasury to buy me.”</p>
+
+<p>There came a hush, and then a ripple of commotion went around the
+table. It died instantly as the spokesman raised a silencing hand. He
+tilted his head back, and through the holes in the mask his eyes bored
+into Cole’s face. For a time not a sound was heard in the room. Finally
+the spokesman <span class="pagenum" id="Page_34">34</span>gave a short, contemptuous laugh. “I see,” he declared.
+“You’re a weakling like most men. You’re a slave to the absurd thing we
+call conscience. I had hoped that you were one of the rare exceptions.”</p>
+
+<p>“Wrong again,” said Cole, smiling. “It isn’t conscience. Anyway, I
+wouldn’t call it that. It is only pride, a foolish pride, perhaps. I
+want to go through life knowing that I can look every man straight in
+the eye and tell him to go to the devil if necessary. I couldn’t do
+that if I were to sell myself. I should become a despicable thing in my
+own eyes, and life wouldn’t be worth living after that. I don’t suppose
+you understand, but that’s just how I feel.”</p>
+
+<p>Seven pairs of eyes were leveled at Cole’s face as his short, crisp
+sentences fell on the tense air. Then came silence, a long and oddly
+vibrant silence during which Cole experienced an unaccountable feeling
+that his life hung in the balance. He could neither understand it nor
+trace it to its source, but the nameless sense of danger grew more
+distinct with every moment.</p>
+
+<p>By instinct his hand went to the hip pocket in which he always carried
+a small, but reliable, pistol. Before his hands could touch the weapon
+a strange thing happened. The spokesman’s arm described a slight
+movement in the dusk, and in a twinkling utter darkness fell. Cole
+stood in blackness so intense that it seemed as though he could touch
+it.</p>
+
+<p>His fingers found the handle of the pistol, but in the next instant his
+hand fell to his side. In that impenetrable darkness the weapon was of
+no more <span class="pagenum" id="Page_35">35</span>avail than a toy. He heard a faint scraping of chairs, then a
+patter of feet. He groped for the chair where the spokesman had sat,
+but it was empty. Gradually the faint sounds ceased, and then came an
+engulfing silence. It was as if every manifestation of life had been
+drained out of the blackness that surrounded him.</p>
+
+<p>Silence—darkness—solitude. Cole, as he dropped into the spokesman’s
+chair, felt as if the three words had suddenly acquired a new and more
+powerful significance.</p>
+
+<hr class="chap x-ebookmaker-drop">
+<div class="chapter">
+<span class="pagenum" id="Page_36">36</span>
+<h2 id="chap_III">CHAPTER III</h2>
+<div class="subheadc">THE TEMPTRESS SPEAKS</div>
+</div>
+
+<p class="drop-cap">FIVE minutes passed. Cole could no longer control his restlessness. He
+got up from the chair and went gropingly across the heavily carpeted
+floor. His footsteps made scarcely a sound, and he had a queer
+sensation that the darkness and silence were insinuating themselves
+into his very pores. It was as if a magic spell had fallen over him. He
+could no longer trust his reason or his senses.</p>
+
+<p>He stopped short as a faint whisper went through the dead silence. With
+head thrown back and straining his ears, he listened. Again the whisper
+came, trailing through the blackness like a disembodied breath. He
+groped in the direction whence the sound came, and now he could hear it
+quite distinctly.</p>
+
+<p>“Mr. Cole!”</p>
+
+<p>Tracing the sound vibrations, he crossed the floor and brought up
+against the wall. Again his name was spoken, and now he had an
+impression that the speaker was only a few feet away. He thought he
+recognized the voice.</p>
+
+<p>“Mr. Cole!”</p>
+
+<p>His highly sensitized ears gauged and dissected each small fraction
+of a syllable. He knew he was not mistaken. The voice belonged to the
+woman who had introduced herself by the absurdly inappropriate name of
+Miss Brown.</p>
+
+<p><span class="pagenum" id="Page_37">37</span></p>
+
+<p>“Where are you?” he asked. He fumbled with his hands in the dark, but
+found nothing but emptiness. He turned and ran his fingers up and
+down the wall until he encountered a metallic object imbedded in the
+paneling. Again his name was called, and he gave a short laugh as he
+realized that the sounds were coming to him through the mouthpiece of a
+speaking tube. The touch of the cold metal against his fingers seemed
+to shatter an illusion. Simple though the contrivance was, it smacked
+of up-to-dateness. A sense of reality broke the spell which the weird
+events of the night had cast over him.</p>
+
+<p>“Hello,” he spoke into the mouthpiece. “You, Miss Brown?”</p>
+
+<p>A brief pause, and then her voice came to him in hurried tones that
+bespoke intense excitement. “Yes, Mr. Cole. I must warn you. I feel
+responsible for your predicament. Awful things will happen if you
+persist in your headstrong course. You must abandon it and accept the
+proposition that was made to you. Otherwise——”</p>
+
+<p>Her voice quavered and broke. The suspended sentence and the words she
+had left unspoken impressed Cole grimly. He could almost see her, white
+and shuddering at the other end of the speaking tube. Though he knew
+she was a clever actress, there was an earnestness in her tones that
+gave him pause.</p>
+
+<p>“You mean these men will kill me unless I accept their vile terms?” he
+asked.</p>
+
+<p>“Oh, they will do worse than that! They are terrible men, Mr. Cole,
+and they are in a desperate <span class="pagenum" id="Page_38">38</span>temper. Death, a hundred deaths, would
+be preferable to the thing they intend doing. Won’t you come to your
+senses before it’s too late? Oh, please——”</p>
+
+<p>Cole laughed into the mouthpiece. “Compose yourself, Miss Brown. Don’t
+worry on my account. I’ve been in tight corners before, and I always
+wriggled out of them somehow. I shall do so this time.”</p>
+
+<p>A sob sounded at the other end, and then all was quiet. Cole drew away
+from the speaking tube. It might have been only another bit of clever
+acting, but Miss Brown’s warning had left him in a state of tingling
+suspense. She had hinted at dire things that were to happen to him,
+and Cole tried to tell himself that she had only been exercising
+her imagination. Such things belonged in the realm of romance and
+melodrama. It was laughable to think that they might happen on the top
+floor of a skyscraper, located close to the world’s financial nerve
+center. The incongruity of it struck Cole as quite amusing.</p>
+
+<p>He chuckled, but in the next instant he sharply caught his breath. A
+sound resembling that of a clicking lock reached his ears. He heard
+nothing more, but he had a feeling that some one had entered the room,
+that he was no longer alone. Instinctively he braced himself to resist
+an attack. His ears were keyed to catch the slightest sound; every
+muscle in his body had the tension of a cocked trigger.</p>
+
+<p>He stood with his back against the wall, all his senses quiveringly
+alert. He could neither hear <span class="pagenum" id="Page_39">39</span>nor see, but he knew some one was
+steadily approaching from the farther end of the long room. Presently
+he could hear sounds of breathing, but the prowler’s progress was
+still muffled by the heavy carpet. Now a little thud signified that
+the intruder had walked up against the circular table, so he could
+be no more than a few feet from where Cole stood. The fact that he
+could not see who it was that was coming toward him made the suspense
+nerve-racking.</p>
+
+<p>Suddenly he thought of matches. He searched his pockets, but the little
+case in which he usually carried them was empty. Somewhere in the room
+there must be an electric-light switch, but it was not likely he could
+find it in the dark.</p>
+
+<p>He peered sharply into the blackness. Now his ears caught a pawing
+sound, like that of some one crawling on hands and knees. He bent
+forward a little, shoulders squared, for he knew the prowler was only a
+foot or two away. Evidently he hoped Cole was unaware of his entrance
+and expected to take his victim by surprise.</p>
+
+<p>A fumbling hand swept Cole’s knees, and he kicked out his foot with
+great force, foiling the attempt to trip him. A startled yell testified
+to the effectiveness of the kick, but in the next instant Cole knew
+that his adversary had risen to his feet and was changing his tactics.
+His fist struck out, but it landed on a body hard and firm as rock, and
+the only apparent result of the blow was a stinging sensation in his
+knuckles. He tried to strike again, but now his shoulders were seized
+in a powerful grip <span class="pagenum" id="Page_40">40</span>that pinned his arms to his side and rendered him
+helpless.</p>
+
+<p>His mind worked quickly, while the enormous weight of his adversary
+bore him down. Evidently he was a huge man, and his arms were hard
+as flails. Even if Cole’s hands had been free, his fists would have
+made no stronger impression on the man’s body than on a wall of brick.
+Though nimbler and more wiry than his opponent, Cole knew he could not
+match him in brute strength and physical endurance. His only hope lay
+in releasing his arms and, striking at the fellow’s face, batter him
+into insensibility.</p>
+
+<p>He writhed and wriggled in the powerful embrace of the gigantic arms,
+resisting the downward pressure till he felt as if his spine must snap.
+Inch by inch his opponent was bending him to his knees, and all the
+while his arms felt as if they were caught between metal springs. In
+vain he put every ounce of strength into the struggle; the mountainous
+body of his adversary was constantly forcing him downward. Already his
+knees were touching the floor, and his neck felt as if it were being
+gradually wrenched out of shape.</p>
+
+<p>His breath grew weak and fluttering. His heart pounded against his ribs
+like a trip hammer. In the blackness tiny specks whirled before his
+eyes. He knew the struggle must end soon, and the realization seemed
+to kindle a flame within him. An idea shot like a flash through his
+reeling mind.</p>
+
+<p>Suddenly he grew limp in the sturdy arms of his opponent. With a
+grunt of satisfaction the latter let go his hold, and Cole lay flat
+and inert <span class="pagenum" id="Page_41">41</span>on his back. For a few moments he drank huge gulps of air
+into his straining lungs. Then, with the elastic swiftness of a spring
+suddenly released, he leaped to his feet. With one hand he located his
+adversary, with the other he drove a savage blow straight into the
+man’s face.</p>
+
+<p>A short cry of pain and rage broke from the other’s lips. His hands
+fumbled at Cole’s throat for a strangle hold, but the merciless
+hammering of the latter’s fists drove him steadily backward. Whenever
+his fingers tightened around Cole’s windpipe a rain of smashing blows
+to nose and mouth forced him to relax his hold and retreat a little
+farther toward the wall. Cole, his strength electrified by the joy of
+battle, did not notice that his knuckles were bruised. Time and again,
+with a sureness of aim that surprised himself, he drove them into the
+other’s torn and mangled face. Already a stertorous breathing told that
+his adversary was becoming groggy. Cole summoned all his strength for a
+final knock-out blow.</p>
+
+<p>He flung his arm backward, and in the same instant the other uttered a
+loud yell. Cole cut it short with a crashing thrust of his fist. With a
+gasp his opponent went to the floor. For a moment he gave himself over
+to the thrill of victory, but in the next instant he was all alertness.
+A faint click signified that the door had opened, and now several pairs
+of feet were stealing swiftly across the floor.</p>
+
+<p>Cole whirled around on his heels, but a stalwart form collided with
+him, nearly sweeping him off his feet. Another hurled himself upon him
+from <span class="pagenum" id="Page_42">42</span>behind, and a third jerked his legs from under him. With a sharp
+sense of bafflement, Cole fell headlong to the floor. He struck out
+with hands and feet, fighting with desperate vehemence, determined to
+inflict all the injury he could on his opponents.</p>
+
+<p>But he was outnumbered three to one, and something of his strength had
+been spent in the earlier encounter. Defiantly he met the onslaught,
+but he was overpowered by numbers. Eventually they laid him on his
+back, and then his adversaries shackled his hands and feet with stout
+cord. He thought they were handling him with strange gentleness, and he
+wondered if they were saving him for another ordeal. He remembered, as
+he was picked up and carried, that Miss Brown had said something about
+a fate worse than a hundred deaths.</p>
+
+<p>In silence the little procession passed through a door, and presently
+Cole was placed on a cot. In a few moments the men walked out, and once
+more he was left alone in impenetrable darkness. Not a word had been
+spoken by his captors, and he had not obtained a single glimpse of
+their faces. The whole episode had been enacted in silence and under
+cover of darkness.</p>
+
+<p>The door opened just as his mind was shaking off the numbness that had
+seized it when he fell. Some one walked up to the cot where he lay. For
+a few moments no sound was heard save the slow breathing of the two
+men. Finally the other spoke, and Cole recognized the voice of the one
+who had acted as spokesman for the group around the circular table.</p>
+
+<p>“You’re an obstinate man, Mr. Cole. We have <span class="pagenum" id="Page_43">43</span>made you a very flattering
+proposition, and you have seen fit to reject it. I have come to offer
+you one more chance to comply with our wishes.”</p>
+
+<p>“And if I refuse,” said Cole evenly, “you will kill me, I suppose. I am
+beginning to think you are quite capable of it.”</p>
+
+<p>“Oh, no!” The other man laughed softly. “We know you are not the kind
+of man that’s afraid of death. Something stronger than fear for your
+life is needed to bend you to our will. But we will bend you sooner or
+later. Make no mistake about that.”</p>
+
+<p>The words were spoken in a tone of calm assurance that impressed Cole
+against his will.</p>
+
+<p>“How, if I may ask?”</p>
+
+<p>“By a form of persuasion that is far more powerful than the fear of
+death. After all, death is nothing. Only a dip into a void. A little
+suffering, perhaps, and then nothingness. There are things that are far
+worse. Mr. Cole, did you ever stop to consider what your life would
+amount to if you should suddenly lose your mind?”</p>
+
+<p>“What?” Cole gave an involuntary shudder.</p>
+
+<p>“Suppose that keen mind of yours should become a blank. Suppose that
+your wonderful mental faculties were to desert you, that you were to
+become a leering, tottering wretch, inspiring loathing and horror in
+your fellow men. Can you picture such a fate, Mr. Cole? Death would be
+a thousand times more merciful, yet you would lack the incentive to
+kill yourself. What could be worse?”</p>
+
+<p>Cole was silent. The darkness gave free rein to <span class="pagenum" id="Page_44">44</span>his imagination, and
+the picture he saw sent a cold shiver down his spine.</p>
+
+<p>“All that life means to you would be blotted out,” the other went on
+with remorseless eloquence. “Instead of matching your wits against a
+man’s problems, as at present, you would probably be devoting your
+time to childish amusements. Imagine yourself placing buttons in a row
+and building houses out of blocks. You would be dragging a useless and
+broken body through life until——”</p>
+
+<p>“Stop it!” said Cole. “You’re in more danger of losing your mind than I
+am. Yours is already a bit twisted, unless I’m mistaken.”</p>
+
+<p>“Don’t fool yourself. Unless you give us a reasonable guarantee that
+you will comply with our wishes, you will be a grimacing lunatic by
+morning. A very simple operation on the brain will do it. Among those
+seven men whom you saw around the circular table is a noted surgeon.
+Everything, including the ether and the instruments, will be ready in a
+few minutes. There is still time for you to come to your senses.”</p>
+
+<p>In the back of Cole’s mind was a hazy suspicion that he was dreaming,
+but the other’s calm and softly penetrating tones gave him a feeling of
+reality.</p>
+
+<p>“You wouldn’t——” he began.</p>
+
+<p>“Ah, wouldn’t we? Just wait and see. Perhaps I can convince you.”</p>
+
+<p>Cole heard his footfalls cross the floor, and then a door opened and
+closed. For a few minutes he was alone, trying to arrange in an orderly
+process the odds and ends of the night’s amazing happenings. <span class="pagenum" id="Page_45">45</span>His
+mind staggered before the task, and suddenly the door opened again.
+He had a vague impression that two men were entering, and that they
+were carrying a burden between them. They moved about quickly in the
+darkness, and now and then they whispered in tones so low that Cole
+could not hear them.</p>
+
+<p>A light flashed on, and in the same instant the door closed. After the
+long period of utter darkness, the sudden glare had a blinding effect.
+Cole blinked his eyes, but after a little he opened them wide in
+astonishment, and the sight that met them drew a long, trembling gasp
+from his lips.</p>
+
+<p>There was only one other man in the room, a shivering, gibbering wreck
+of a man whose grimacing features and hollow cackle sent a series of
+chill shivers through Cole’s body. For a long time he stared into the
+leering, slowly twitching face before he was able to realize that the
+wretch, seated a few feet from his cot, was Malcolm Reeves.</p>
+
+<hr class="chap x-ebookmaker-drop">

+<div class="subheadc">“YELLOW”</div>
+</div>
+
+<p class="drop-cap">WHEN he first went to work on the case of Reeves’ mysterious
+disappearance, Cole had been shown several photographs of the missing
+man. Along the numerous twistings of the trail, he had carried with him
+a mental picture of a fine intellectual face, deep and rather somber
+eyes, a long nose, whose slenderness hinted at aristocratic breeding,
+a clean-cut jaw that denoted a great deal of aggressiveness, and lips
+that were a trifle too full and might have suggested sensuality, if the
+broad slope of the forehead had not conveyed a dominant impression of
+the student and the thinker. The picture in Cole’s mind had represented
+a man about fifty years old, with a virile personality and quiet tastes.</p>
+
+<p>The contrast between his mental image of Malcolm Reeves and the
+miserable creature, now sitting a few feet away, was so sharp that the
+comparison gave Cole a profound shock. His clothing hung loosely over
+his bony frame, and he seemed to have aged decades in the three weeks
+that had elapsed since his disappearance. His shoulders were hunched
+down a little, his head was bent forward, and the eyes stared rigidly
+into space, as if he were seeing something in the distance. His lips
+were twisted into a fixed, vacant smile that impressed Cole as the most
+hideous thing he had ever seen.</p>
+
+<p><span class="pagenum" id="Page_47">47</span></p>
+
+<p>He tried to spring from the cot, momentarily forgetting that his arms
+and legs were bound. He sank back with a mutter of exasperation. Not
+much imagination was required to guess that the men who had brought
+about his own plight were also responsible for the condition of Malcolm
+Reeves.</p>
+
+<p>Again something drew his glance to the insane man. The revolting
+picture seemed to hold Cole with an uncanny fascination. “What’s
+happened?” he inquired, realizing a moment later that he might as well
+have addressed a wooden image.</p>
+
+<p>Reeves was still gazing fixedly at the opposite wall. There was a look
+of insane glee in his shrunken eyes. He bent forward a little more, and
+then his lips began to move. “Yellow,” he said. “Pretty yellow!”</p>
+
+<p>The soft-spoken words and the giggle that followed caused Cole to
+shudder. He could see that Reeves’ mind, or the pitiful remnant of it,
+was reveling in some childish fancy. The wreckage of a once splendid
+intellect was horrible to behold.</p>
+
+<p>“What do you see?” he asked, wondering whether the man was capable of
+any form of response.</p>
+
+<p>The other’s face brightened, but Cole thought it was only an external
+glow, a reflected light rather than one kindled from within. He
+recoiled inwardly as another stream of giggling mirth flowed from the
+insane man’s lips.</p>
+
+<p>“Yellow,” said Reeves again. “Pretty yellow!”</p>
+
+<p>His expression became more rapt. His smile grew broader and deeper, but
+to Cole it seemed nothing more than a contortion of facial muscles.
+<span class="pagenum" id="Page_48">48</span>He wondered whether the two words were all that was left of the man’s
+vocabulary. He felt a desire to test him and see if there was not a
+remaining scrap of intellect that could be aroused.</p>
+
+<p>“Listen, Mr. Reeves,” he said sharply. “When did you last see Professor
+Carmody?”</p>
+
+<p>The giggling ended in a quick intake of breath. Reeves’ smile faded
+as abruptly as if an invisible hand had blotted it out. Watching him
+intently, Cole could see that his question had touched a slumbering
+chord in the man’s mind. Fear and something akin to hate blazed in the
+shrunken eyes. It was a startling transformation, and Cole observed it
+in wonder. He had mentioned Carmody’s name on the spur of a vagrant
+impulse, wondering whether it would awaken a recollection in the débris
+of Reeves’ intellect. The effect was far beyond his expectations.</p>
+
+<p>“Carmody!” said the insane man, and each syllable cut like a knife
+through the silence. “Carmody!”</p>
+
+<p>He drew a shaking hand across his brow, and Cole fancied something was
+stirring in the dark corners of his mind. His face took on a strained
+look, as if he was trying to exercise the shattered remnants of his
+intellect. There was a flicker of returning sanity, a feeble ray of
+awakening reason.</p>
+
+<p>It did not last long. Reeves gave a little shudder, there was a
+trembling gleam in his eye, then the fatuous grin came back to his
+lips, and once more he mumbled in rapt tones: “Yellow. Pretty yellow!”</p>
+
+<p>Cole turned his head away with a shiver. His experiment had shown the
+hopelessness of the insane man’s condition, but it had also suggested
+<span class="pagenum" id="Page_49">49</span>several things to Cole. A recollection of a terrifying nature
+seemed to be buried in the wreckage of Reeves’ mind, and evidently
+it had something to do with Professor Carmody. Cole had felt certain
+for a long time that the professor was responsible for the man’s
+disappearance, but he had not cared to jeopardize his case by taking
+action before he had sufficient evidence in his possession, as a
+premature move on his part might have brought disastrous results. At
+that time he had not been sure whether the missing man was dead or
+alive. If still living, his safety might be endangered by hasty action,
+for Carmody would not hesitate to kill him if he thought it advisable.
+So Cole had waited, patiently biding his time and slowly, but surely,
+strengthening the meshes in which he hoped to entangle the professor.</p>
+
+<p>Now he wondered to what extent his course had been correct. The
+maniac’s startling reaction to the mention of Carmody’s name seemed to
+confirm at least a part of his theory. What he could not understand
+was how Reeves, granting that the professor was responsible for his
+abduction, happened to be in this place of dark intrigue and baffling
+mystery. Evidently there must be a connecting link between Professor
+Carmody and the seven masked men who had sat around the circular table.
+Likely as not they were accomplices, banded together for the attainment
+of some secret object. That would at least explain why the seven men
+were so determined that Cole should drop the Carmody case, though it
+explained nothing else.</p>
+
+<p>A slight sound interrupted the speculations with <span class="pagenum" id="Page_50">50</span>which he had tried
+to relieve the tension he felt. He turned his head a little and saw
+that the door had opened a crack. A hand was inserted through the
+narrow opening. For a moment it fumbled over the wall, then came a
+faint click, and once more the room was dark. Men were moving about in
+the black for a time, and then all was quiet. The silence seemed to
+indicate that Cole was alone in the room, but he had an indefinable
+feeling that some one was standing beside his cot. In a moment his
+impression was confirmed.</p>
+
+<p>“Mr. Cole,” said a voice, and he recognized it at once, “I trust that
+what you have just seen has put you in a more reasonable frame of mind.
+Unless you comply with our wishes we shall do to you what we did to
+Malcolm Reeves.”</p>
+
+<p>Cole strained spasmodically against the cords that fettered his hands
+and feet. In the darkness his imagination sketched a picture of Reeves’
+hideously grinning face. For a moment he could almost hear the maniac’s
+insane cackle. He banished the vision by sheer force of will.</p>
+
+<p>“There’s a great deal of finesse about your methods,” he ironically
+observed. “I guessed, of course, that Reeves was brought in here to
+serve as an object lesson to me. It was quite impressive.”</p>
+
+<p>“And you have reconsidered?” asked the other hopefully.</p>
+
+<p>Cole lay absolutely still on his back. It was all he could do to
+exclude the disturbing pictures of Reeves from his mind. Whenever a
+glimpse of it came back to him he felt a weakness that put him in fear
+of himself. “Not exactly,” he managed to <span class="pagenum" id="Page_51">51</span>say in steady tones. “I have
+merely been taking my own measure, as it were, trying to determine
+whether the loss of pride and self-respect is worse than the loss of
+one’s sanity.”</p>
+
+<p>“And what is your conclusion?”</p>
+
+<p>“I am still in doubt. There are so many ways of looking at the
+situation. For instance, one thing to be considered is that lost
+self-respect may be regained, while insanity is in most instances
+incurable.”</p>
+
+<p>“Excellent,” murmured the other. “That’s a very rational way of looking
+at the proposition. Such being the case it should not be difficult for
+you to choose between the two alternatives.”</p>
+
+<p>“But it is,” protested Cole. “There is still another thing to be
+considered. Suppose I were to accept your terms. All I could give you
+would be my word of honor that I would live up to them.”</p>
+
+<p>“Quite sufficient,” the other put in. “We know you are not the kind of
+man who goes back on his word.”</p>
+
+<p>“Thanks,” said Cole sarcastically. “Just the same one’s word of honor
+is a rather intangible thing. You can’t bind me with a contract. It
+would not be legal, no matter how ingeniously worded, and it might
+incriminate yourselves. I am not in position to give you any pledges.
+You would have to be content with my bare promise. It would be
+sufficient in any ordinary case, but circumstances alter everything. I
+realize I am at the mercy of a gang of unprincipled scoundrels.”</p>
+
+<p><span class="pagenum" id="Page_52">52</span></p>
+
+<p>“Your epithets don’t hurt us in the least,” remarked the other man
+icily.</p>
+
+<p>“Didn’t expect they would. But don’t you see that, under the
+circumstances, I would have no hesitancy at all about giving you a
+promise that I didn’t intend to keep? I am not a bit quixotic, and I am
+too practical to indulge in cheap heroics. I have no ambition to become
+the hero of a tawdry melodrama. In order to escape a fate like the one
+you inflicted on Reeves, I would promise anything, and so would every
+other man whose head isn’t full of moonshine. You follow me?”</p>
+
+<p>“Perfectly. You are trying to make out that we have no hold over you.
+Your reasoning isn’t bad, but you forget one thing. As it happens, we
+are in a position to exact a pledge from you, one that will hold you to
+us for life.”</p>
+
+<p>“What is it?”</p>
+
+<p>The other gave a soft laugh. “You saw what a hopeless case Reeves is.
+There’s no reason why he should go on living any longer. The merciful
+thing to do is to put him out of his misery.”</p>
+
+<p>“You mean——”</p>
+
+<p>“Exactly, Mr. Cole. You are to seal the promise you give us by hustling
+Reeves off to a better world. We have planned it so that we will be
+able to prove that you killed him. Having incriminated yourself to that
+extent, and with the evidence in our possession, we need have no fear
+that you will go back on your word of honor. And now that we thoroughly
+understand each other, I must ask you to decide promptly. Our time is
+valuable.”</p>
+
+<p><span class="pagenum" id="Page_53">53</span></p>
+
+<p>A few moments passed in silence, but to Cole they were like weeks.
+Never before in all his life had so many thoughts and emotions been
+crowded into such a narrow space of time. He felt weak and shaken when
+it was over, but his voice was clear. “My answer is no,” he declared.
+“If I were able I would give it to you in a more emphatic manner.”</p>
+
+<p>“Sorry, Mr. Cole,” replied the other. “I won’t accept your decision
+as final, however. I trust you will reconsider before you become
+unconscious under the ether.”</p>
+
+<p>With that he went out, leaving an ominous silence behind him. Cole
+tore frantically at the cords around his wrists, but they only cut the
+deeper into his flesh. He could see no escape from the awful fate that
+awaited him. Time and again the picture of Reeves’ fatuously grinning
+face came back to him, causing him to writhe in mental torment. A
+tempting voice seemed to whisper in his ear, turning his thoughts into
+strange channels. To end a life that was worse than a living death
+appeared not such a dreadful thing to do. Cole himself would have
+preferred to die rather than suffer a fate like Reeves’. If he should
+ever fall into such a condition he would consider the man a benefactor
+who ended his misery.</p>
+
+<p>He shook himself violently. A clammy perspiration was bathing his
+forehead. With a mental and physical paroxysm he brushed away the
+temptation to which he had nearly yielded a moment ago. Footsteps
+were approaching the door, and he knew a critical moment was at hand.
+Something within <span class="pagenum" id="Page_54">54</span>him that was stronger than reason and logic shrank
+from the mere thought of taking Reeves’ life. He wondered if there was
+no other alternative.</p>
+
+<p>He tried to take a calm view of the situation. Though his hands and
+feet were tightly bound his persecutors evidently had not thought it
+necessary to strap him to the cot, since he would soon be under the
+influence of the ether. By experimenting he found that he could turn
+over on his sides and, thanks to the fact that his hands had been tied
+in front instead of behind, he was able to move his arms up and down
+and in a horizontal direction. Since he could not use his hands he did
+not see how he could turn this circumstance to his advantage, yet it
+continued to tantalize his imagination.</p>
+
+<p>The door opened, and his ears told him that several men were entering
+the room. For a time they moved about in the darkness, as if making
+preparations of some sort. After a little the footsteps receded, and
+then the door opened and closed once more. Cole guessed that all but
+one or two of the men had withdrawn. After another brief delay, the
+lights flashed on once more, this time illuminating a different scene.</p>
+
+<p>Reeves was back in the room, occupying the same chair in which he had
+sat the other time, but now his limbs were as tightly manacled as
+Cole’s own. He moved his head slowly from side to side, as if sensing
+something unusual in the air, but his vacant stare showed that he had
+not the faintest inkling of what was going on.</p>
+
+<p>After a glance at him, Cole looked away. Not far from the cot stood a
+tall man with a black <span class="pagenum" id="Page_55">55</span>beard that covered nearly his entire face. He
+was holding a number of surgical implements to the light, giving each
+one a critical inspection before he placed it on a small table with a
+glass top that stood beside the cot. Cole could not restrain a shudder
+as he saw how calmly the man examined the sinister-looking little
+tools. There was a professional air about him that in Cole’s mind
+stamped him as a surgeon.</p>
+
+<p>Again his glance moved to the insane man, whose dull gaze seemed to be
+taking in each detail of the scene. The meaning of the little knives
+and the presence of the black-bearded man was terrifyingly clear.</p>
+
+<p>The surgeon placed the last of the knives on the table beside the
+cot. They lay there in plain view, so close to Cole that if his hands
+had been free he could have reached out and touched them. The long,
+slender metal blades gleamed diabolically in the electric lights, and
+he wondered if they had been placed like that for the sole purpose of
+impressing their hideous significance upon him.</p>
+
+<p>The black-bearded man came closer to the cot, and Cole caught a full
+view of his face. He had seen it once before, though only dimly,
+for the surgeon was one of the seven who had sat in the dusk at the
+circular table. He had worn a mask then, but the black beard, the high
+forehead and the bald spot on top of his head were unmistakable. Now
+his features were unveiled, and in this circumstance Cole saw a grim
+significance. The surgeon no longer had any reason to fear that Cole
+might recognize him if they should meet again.</p>
+
+<p><span class="pagenum" id="Page_56">56</span></p>
+
+<p>He stopped beside the glass-topped table and, with hands clasped at his
+back, fixed a tranquil gaze on the reclining man. “You have one more
+chance, Mr. Cole,” he remarked in a casual tone. “Hadn’t you better
+reconsider your refusal?”</p>
+
+<p>Cole looked up into the bearded face with a feeling that there was
+something peculiar about it, but his mind was too agitated to analyze
+the impression. In a playful manner the surgeon picked up one of the
+knives, holding it so that the light flashed against the keen blade.</p>
+
+<p>Cole was trying to frame an answer, but just then something drew his
+gaze to the insane man. Reeves was straining forward in his chair,
+bending his weight against the fettering cords. From where he sat he
+had a clear view of both Cole and the surgeon, and his eyes were fixed
+with wild intensity on the knife in the latter’s hand. Time and again
+he opened his lips, but the only sound that came was a hoarse rattle in
+his throat.</p>
+
+<p>“Well, Mr. Cole?”</p>
+
+<p>The surgeon, paying no attention to the lunatic, looked impatiently
+at Cole. Reeves, with mouth gaping and features horribly distorted,
+continued to stare at the knife.</p>
+
+<p>“You refuse?” The surgeon waited a moment longer for an answer; then,
+with a shrug, he replaced the knife and stepped aside. Cole felt a
+sudden rush of blood to his head. If he was to escape a fate worse than
+death he must act at once. He spurred his wits to think of something
+to do. A tinkling, like that of a jar or a bottle being moved, sounded
+in the room. Again he bent his mind to <span class="pagenum" id="Page_57">57</span>the seemingly hopeless task
+of finding a way out, but, even in this moment of desperate peril, he
+could not take his gaze from the insane man’s face.</p>
+
+<p>Reeves sat with shoulders hunched up and head turned a little to one
+side. Now and then his mouth twisted at the corners; from time to time
+a shudder broke the tension of his figure. A series of slight gurgling
+sounds fell on the stillness at intervals. All the while his eyes, with
+a smoldering something in their depths, were fixed on the knives spread
+out on the glass-topped table.</p>
+
+<p>Suddenly Cole’s body executed a little writhing motion. His nostrils
+sucked in a strong, sickening odor. With a sponge in his hand, the
+surgeon was coming toward the cot.</p>
+
+<p>Once more, in a delirium of suspense, Cole glanced at the insane man.
+The quick dilation of Reeves’ nostrils told he also had noticed the
+ether. The chair creaked as he put his weight against the cords. There
+was a look on his face that Cole felt would follow him through the
+night of madness that threatened to engulf him. Reeves’ chest heaved
+violently, his whole body seemed to be rocked by a tumultuous emotion,
+and finally a long and oddly vibrant cry broke from his lips.</p>
+
+<hr class="chap x-ebookmaker-drop">
+<div class="chapter">
+<span class="pagenum" id="Page_58">58</span>
+<h2 id="chap_V">CHAPTER V</h2>
+<div class="subheadc">DISGUISED</div>
+</div>
+
+<p class="drop-cap">TO Cole’s rapt gaze the insane man presented a picture at once fearful
+and fascinating. Reeves was no longer looking at the keen-bladed
+knives, but now he was staring at the black-bearded surgeon with an
+intensity that seemed to strain every nerve and muscle in his body. The
+knotted cords at his temple swelled and took on a livid hue. Slowly and
+shakily he drew himself erect in the chair, and then his whole body was
+rocked by a paroxysm so violent that, for an instant, Cole thought the
+cords were about to snap.</p>
+
+<p>The surgeon, with the reeking sponge in his hand, turned and watched
+the maniac. A smile twisted the bearded lips, and he stepped to the
+chair and spoke a few words in Reeves’ ears. The insane man’s chest
+heaved out, but the cry and the paroxysm seemed to have exhausted his
+energies, and only a feeble, fluttering moan came.</p>
+
+<p>The spectacle had held Cole spellbound. Now, while the surgeon was
+leaning over the insane man and whispering in his ear, a sudden
+realization of his peril caused him to throw off the weird fascination
+which the scene had cast on him. He had only a few moments in which to
+act. Soon the reeking sponge would be at his nostrils, deadening his
+mental faculties.</p>
+
+<p>His darting glance fell on the knives lying on the <span class="pagenum" id="Page_59">59</span>glass-topped table
+beside the cot. They were so close to him that they seemed to mock and
+taunt him. Again it occurred to him that they had been placed like that
+for the sole purpose of impressing their infernal purpose upon him and
+battering down his fortitude. It had been a touch of refined cruelty
+on the black-bearded man’s part, but it only strengthened Cole’s
+determination not to yield.</p>
+
+<p>Suddenly, as he kept looking at the knives, the gleam of an inspiration
+crept into his narrowing eyes. He cast a swift glance about the room.
+The black-bearded man was still occupied with Reeves and stood with his
+back turned to the cot. Cole, trembling with excitement, turned over on
+his side and wriggled as close to the edge of the cot as he could. He
+reached out his manacled hands over the glass-topped table. The cords
+around the wrists gave the fingers considerable leeway. In an instant
+they had closed around the handle of the nearest knife.</p>
+
+<p>Cole tingled from head to foot. The subtle bit of strategy by which the
+black-bearded man had hoped to shatter his victim’s nerve had now been
+turned to Cole’s advantage. It gave him a fighting chance, though the
+odds were still overwhelmingly against him. His lips curled a little,
+and there was a belligerent sparkle in his eyes. Turning over on his
+back he dropped the knife beside him on the pillow, so that his head
+would temporarily screen it from the surgeon’s sight. Then, letting his
+arms fall limply back against his abdomen, he waited for the surgeon to
+act.</p>
+
+<p>Presently the black-bearded man turned away <span class="pagenum" id="Page_60">60</span>from Reeves and stepped up
+to the cot. Cole lay motionless, with eyes half closed, as if partly
+dazed by contemplation of the terrible fate that awaited him. Inwardly
+he was straining and quivering with suspense. As yet the surgeon did
+not seem to have noticed that one of the knives was missing from the
+table, but he might do so any moment, and then Cole’s only hope would
+be gone.</p>
+
+<p>“Well, Mr. Cole?” he asked lightly. “For the last time I ask you to
+reconsider your refusal.”</p>
+
+<p>Cole lay very still. The last few minutes of suspense seemed to have
+wrought a great change in him. His lips moved as if he were trying to
+speak, but was too weak to use his voice.</p>
+
+<p>The surgeon grinned into his beard. Evidently he thought the knives
+placed so close to his victim’s side had exerted the intended
+psychological effect.</p>
+
+<p>“Have you anything to say?” he asked, bending over the cot in an effort
+to catch Cole’s faintly mumbled words.</p>
+
+<p>Cole flexed his muscles for action. The moment for which he had waited
+was at hand. His chance had come; everything depended upon how he used
+it. He mumbled again, and the surgeon’s head came a little closer to
+his chest.</p>
+
+<p>“A little louder, please,” said the black-bearded man.</p>
+
+<p>Slowly, by imperceptible degrees, Cole drew up his manacled hands
+toward his chin. Suddenly his arms shot upward, forming a circular loop
+that instantly descended over the surgeon’s head. With a startled cry
+the black-bearded man tried to draw back, but the arms that encircled
+his shoulders <span class="pagenum" id="Page_61">61</span>were as strong and hard as springs of steel. He
+struggled frantically, but the encircling grip pinned his arms tightly
+to his sides, and his head was constantly being forced lower and lower
+toward the reclining man’s chest. The sponge had dropped from his hand
+the moment Cole’s arms were flung around his neck.</p>
+
+<p>An exultant thrill went through Cole as the other’s resistance grew
+feebler. Now the surgeon’s head was almost level with his face. The
+only sounds in the room were the hard panting of the adversaries and
+an occasional giggle from the insane man. Fumes of ether were slowly
+filling the air.</p>
+
+<p>Cole turned his head. In an instant the handle of the knife was firmly
+gripped between his strong, even teeth. He thrust out his jaw, and the
+point of the weapon grazed the black-bearded man’s throat. Cole saw
+a look of fear creep into the man’s eyes. The surgeon made a final
+attempt to wriggle free, but Cole’s arms held him as in a vise. Once
+more the knife, tightly clasped between Cole’s jaws, scratched the
+other’s flesh. He remarked again the look of terror that was stamped
+on the surgeon’s face. In view of the diabolical fate which the man
+had meant to inflict on him Cole was human enough to enjoy the other’s
+agony.</p>
+
+<p>Suddenly he bent a sharper look on the man’s face. Once before he had
+wondered why there seemed to be something peculiar about it, but this
+was his first chance to examine the features at close quarters. Now he
+noticed that the beard which covered most of the face had an unnatural
+appearance. There were lines about the eyes that <span class="pagenum" id="Page_62">62</span>did not seem quite
+genuine, and the exposed portions of the skin had an odd coloring.
+Obviously the man was disguised, and Cole could see that it had been
+rather cleverly done. He wondered why the disguise had been put on,
+since the surgeon had had every reason to expect that Cole would
+leave the room a raving lunatic and that there would be no danger of
+recognition if they should meet again.</p>
+
+<p>He had not time to think further about it. The deadlock was only
+temporary; any fortuitous incident might upset Cole’s advantage;
+instantly the door might open and admit one or more of the other
+members of the gang. Just now he had the surgeon at his mercy. Only a
+little slash with the knife, clamped between his teeth was needed to
+open an artery, but that would not release him from his predicament.
+Though he might be able to sever the cords around his ankles he could
+not move his hands with sufficient freedom to cut the strings around
+his wrists. While he was casting about for a plan a muffled groan of
+fright and pain broke from the surgeon’s lips. Unconsciously Cole had
+once more scratched the man’s throat with the knife.</p>
+
+<p>“You’re killing me!” protested the other man in a feeble voice.</p>
+
+<p>“It would serve you right,” declared Cole unfeelingly. “I don’t know
+why I should have any compunction about killing a rat of your kind. We
+might come to some arrangement, however. What will you do if I spare
+your life?”</p>
+
+<p>“Anything, anything you say.”</p>
+
+<p>Cole considered. The thing of first importance <span class="pagenum" id="Page_63">63</span>was to get his hands
+free of the cords. In his present position, with his arms pinned
+tightly in Cole’s embrace the surgeon could not untie them, and Cole
+did not see how he could give the man any freedom of movement without
+imperiling his own advantage.</p>
+
+<p>“I am going to give you a chance for your life,” he said, “but if you
+make the slightest false move you die instantly. Understand that?”</p>
+
+<p>“I’ll do whatever you say.”</p>
+
+<p>“All right, then. Turn over.”</p>
+
+<p>Cole relaxed his hold a trifle, and the surgeon turned in his arms. The
+point of the knife did not leave his flesh for an instant, and at any
+moment Cole could have inflicted a mortal wound by merely thrusting his
+head forward. Now, with the end of the blade in dangerous proximity to
+the surgeon’s jugular vein, Cole gingerly released one of the man’s
+arms, then commanded him to untie the cords around his wrists. The
+black-bearded man obeyed, and Cole transferred the knife from his mouth
+to his right hand. In a short time his feet had been released, and now
+he flung the surgeon aside and slipped from the cot.</p>
+
+<p>Reeves had watched the proceeding with a dull stare. Now and then a
+hoarse giggle of glee had escaped him.</p>
+
+<p>The surgeon got to his feet and drew a long breath of relief. His eyes,
+with a glint of lingering fear in their depths, watched Cole admiringly.</p>
+
+<p>“You’re a great scrapper, Mr. Cole,” he admitted. “You turned the
+tables with a truly artistic touch. For a time I was in fear for my
+life. There was <span class="pagenum" id="Page_64">64</span>no time to explain, and you wouldn’t have believed me
+anyway.”</p>
+
+<p>“Explain?” Cole asked contemptuously. The little knife was still
+clutched tightly in his hand. “One doesn’t expect explanations from
+curs of your type.”</p>
+
+<p>The surgeon laughed, and in the same instant his fingers touched a
+button. Cole flexed his muscles for another supreme test. Out of the
+corner of an eye he watched the surgeon; the other eye was fixed on
+the door. In a moment or two it would probably open in response to
+the surgeon’s ring, and men would come tumbling upon him from all
+directions. Cole smiled grimly. He would die fighting rather than
+expose himself to the other and more terrible fate from which he had
+just escaped.</p>
+
+<p>The door opened, and he poised himself, ready to spring forward.
+The nerve-racking suspense, which he had undergone on the cot, was
+forgotten now. His eye was clear, and his brain was rapidly throwing
+off the ether fumes that had escaped from the surgeon’s sponge. The
+hand in which he held the knife came upward, prepared to strike down
+the first man who should approach.</p>
+
+<p>Some one entered through the open door, and the arm fell limply to
+Cole’s side. With gaping mouth he stared at the newcomer who executed a
+profound bow, while he pointed to the outer room. “Will you kindly step
+this way, Mr. Cole?” he asked in the courteous tones of a well-trained
+servant.</p>
+
+<p>Cole laughed. The sudden reaction made him feel giddy. He had expected
+at least half a dozen <span class="pagenum" id="Page_65">65</span>men to pounce on him when the door opened. By
+contrast there was something ludicrous about the salaaming figure, now
+confronting him.</p>
+
+<p>“If you please, Mr. Cole.” The man again waved his hand toward the
+outer room, and Cole obligingly followed his direction. There seemed
+to be nothing else to do than wait for the other side to make the next
+move. If he was walking into a trap, as appeared not at all unlikely,
+he still had the knife to defend himself with. And that was not all,
+he suddenly remembered; his pistol was still in his hip pocket. It was
+rather odd, he reflected, as he walked behind the servant, that no
+attempt had been made to take it from him.</p>
+
+<p>In a few moments he was back in the long room with the circular table.
+The seven masked men were again grouped around it, and the light was as
+dim as before. The servant ushered him up to the chair occupied by the
+spokesman, then silently glided away. Once more Cole felt seven pairs
+of eyes searching his face, but this time he was aware of a new quality
+in the air.</p>
+
+<p>“You may feel quite at ease, Mr. Cole,” the spokesman began. “I can
+promise that no harm will come to you.”</p>
+
+<p>The calm, matter-of-fact tones incensed Cole when he recalled by what
+a narrow margin he had escaped the fate which these men had tried to
+inflict upon him.</p>
+
+<p>“How magnanimous!” he gibingly exclaimed.</p>
+
+<p>The other chuckled. “Oh, we can understand that you don’t feel
+particularly friendly toward us. Incidentally we know all that happened
+in the <span class="pagenum" id="Page_66">66</span>other room. You acquitted yourself nobly, Mr. Cole.”</p>
+
+<p>“Save your compliments. They are on a par with your promises.”</p>
+
+<p>“You would naturally feel that way after what has happened. Mr. Cole, I
+am going to ask you to forget what occurred in the other room.”</p>
+
+<p>“Forget?” asked Cole incredulously, feeling as though the episode he
+had just passed through would live in his memory till his dying day.</p>
+
+<p>“Well, perhaps that is asking too much,” the other admitted. “By the
+way, your bitterness toward us is natural enough, but don’t you find
+some compensation in the knowledge that you have passed through fire
+unscathed? You remained true to yourself in one of the severest tests a
+man can be subjected to. Isn’t there some satisfaction for you in that?”</p>
+
+<p>“Oh, yes, a lot,” said Cole ironically. “It’s worth something to a man
+to know that nothing can bend him. If you expect me, however, to get
+down on my knees and thank you for giving me a chance to prove myself
+you are mistaken.”</p>
+
+<p>“We don’t expect anything of the kind. I am merely trying to point out
+that you have cause for self-congratulation as well as bitterness. You
+probably won’t be able to forget what has happened, but I am going to
+ask you to dismiss it from your mind temporarily, while I make a new
+proposition to you.”</p>
+
+<p>Cole felt a trifle dazed. The effrontery of the man was unbelievable.
+For a moment he suspected it was all a weird jest. “Go on,” he said
+dryly. <span class="pagenum" id="Page_67">67</span>“Your superb insolence interests me. I am curious to see how
+far it will carry you.”</p>
+
+<p>“You shall see in a few minutes. I will begin by stating certain facts.
+Perhaps later on I shall be able to prove them to their satisfaction,
+but just now I must ask you to accept them as an hypothesis.”</p>
+
+<p>“Proceed,” said Cole. “I’ll try to believe that black is white.”</p>
+
+<p>“That’s practically what it amounts to. The first fact I am asking you
+to accept on faith, for the present, is that we are not responsible for
+Malcolm Reeves’ deplorable condition. An operation was performed on his
+brain, but we had nothing to do with it.”</p>
+
+<p>He paused as if expecting an objection.</p>
+
+<p>“The second fact I am asking you to accept provisionally,” he went
+on when Cole showed no inclination to speak, “is that we are just as
+anxious to solve the Carmody case as you can possibly be. We are more
+anxious, in fact, for we know more about its vast scope and enormous
+complexities than you do. Are you with me so far, Mr. Cole?”</p>
+
+<p>Cole’s shoulder made a seesawing motion. The whole thing was
+preposterous, but there was a quality in the man’s tone that impressed
+him against his will. “You are asking me to believe that you are sheep
+in wolves’ clothing,” he remarked.</p>
+
+<p>“That’s undoubtedly how it looks to you. Won’t you try to brush
+your doubts aside, Mr. Cole? Remember that in due time I will prove
+everything I say.”</p>
+
+<p>Cole’s indignation was cooling. There was something <span class="pagenum" id="Page_68">68</span>about the
+spokesman that seemed to exert a subtle magnetism on him. Already his
+dreadful experience in the other room seemed dim and remote, though a
+few minutes ago he had thought it was indelibly etched on the scroll of
+his memory. “If what you say is true, then why——”</p>
+
+<p>“No questions, please. You would not believe me if I were to answer
+them. All I can say now is that we have excellent reasons for what we
+have done. Some time before long I think you yourself will approve
+them. Just now you must accept my statements on faith. Will you try to
+believe that we had nothing to do with Reeves’ condition and that we
+are on your side in the Carmody matter?”</p>
+
+<p>“You can’t deny that you tried to put me in the same condition Reeves
+is in?”</p>
+
+<p>“We can, but we won’t just at present. What happened in the other room
+I am asking you to dismiss from your mind in order that you may view
+the facts I have placed before you in an unbiased frame of mind. With
+that episode eliminated can’t you place a little temporary credence in
+what I say?”</p>
+
+<p>Cole tried to clarify his thoughts, but without much success. He
+realized with satisfaction that his hand was still clutching the
+knife. He wondered whether, but for his quickness of mind and his deft
+handling of the little weapon, he would not now be a raving madman.
+It seemed strange that he was able to think coolly about the matter,
+and stranger still that he found himself listening to the spokesman’s
+arguments with any degree of seriousness.</p>
+
+<p><span class="pagenum" id="Page_69">69</span></p>
+
+<p>Finally he shook his head. “It won’t quite go down,” he declared. “You
+are asking me to take too much for granted. One’s brain was made to
+think with, and your statements won’t bear too close reasoning. You
+will have to give me your proofs before I can believe you.”</p>
+
+<p>A pause followed his words; then a chorus of whispers went around the
+table. The spokesman leaned over and consulted the man seated beside
+him.</p>
+
+<p>“I don’t blame you,” he declared, again turning to Cole. “After
+all, your skepticism is quite natural. It is even a tribute to your
+intellectual powers, for only children and feeble-minded persons accept
+unsupported statements. Now, as for proofs, let me see. Would you be
+convinced if you should find the man who is responsible for Reeves’
+condition?”</p>
+
+<p>“You know who he is?”</p>
+
+<p>“We have had our suspicions for some time, but we were not certain
+until a short while ago. A delicate operation, by which certain brain
+cells were deadened, was performed on Reeves. We knew Professor Carmody
+could not have performed it, for he is not a surgeon. We began to look
+for an accomplice, and finally we found a man who seemed to fit into
+our theory of the case. Mr. Cole, did you ever hear of Doctor Dickson
+Latham?”</p>
+
+<p>“Never,” said Cole.</p>
+
+<p>“Well, certain circumstances, which needn’t be mentioned just now, made
+us believe that Doctor Latham was the man whom we were looking for. The
+matter was really of no great importance, only one of the minor angles
+of the case, but any <span class="pagenum" id="Page_70">70</span>little light, shed on the corners of the mystery,
+might help toward solving the whole. We felt fairly certain Doctor
+Latham was our man; in the last hour we have become positive of it.”</p>
+
+<p>“In the last hour!” exclaimed Cole. “How?”</p>
+
+<p>“Malcolm Reeves told us.”</p>
+
+<p>“Reeves told you?”</p>
+
+<p>“By his actions, while you were lying on the cot. We had two reasons
+for staging that little scene in the other room. The primary one we
+won’t go into at present. The other was to jog the dead part of Reeves’
+brain back to life, by having him witness the preparations for an
+operation that, in its essential aspects, must have resembled the one
+performed on himself. We hoped that the smell of the ether, the sight
+of the knives and the preparations in general would awaken a slumbering
+memory in his mind. The experiment was only partly successful, but
+Reeves’ actions proved beyond doubt that he recognized the officiating
+surgeon.”</p>
+
+<p>Through the dusk Cole stared into the speaker’s calm face. “Then the
+surgeon——”</p>
+
+<p>“You probably didn’t notice it,” the other interrupted, “but the man
+who officiated as the surgeon was disguised. The disguise was put on by
+one of our men, an expert in that line.”</p>
+
+<p>“I noticed it, and it was a good job,” Cole remarked. “I couldn’t see
+why it was necessary, though.”</p>
+
+<p>“The disguise was put on, not to hoodwink you, but for its effect on
+Reeves.”</p>
+
+<p>“I don’t understand.”</p>
+
+<p><span class="pagenum" id="Page_71">71</span></p>
+
+<p>“But you will when I tell you that the disguise gave the officiating
+surgeon a superficial, but fairly convincing, resemblance to Doctor
+Dickson Latham.”</p>
+
+<p>“Clever, I’ll say!” exclaimed Cole who could appreciate ingenuity even
+in men who had caused him the most agonizing moments in his life. He
+recalled Reeves’ intense agitation while the preparations were in
+progress. At the time he had not known what it meant, but he remembered
+that the surgeon had watched Reeves very closely, and this had given
+Cole his chance to snatch up the knife from the table.</p>
+
+<p>“There is no doubt that Reeves thought he was seeing the man who had
+performed the operation upon him,” the spokesman went on. “One of us
+was watching the scene through a small opening in the wall, and it was
+quite evident that the surgeon’s resemblance to Doctor Latham gave
+Reeves a profound shock. Our suspicions have been confirmed, but as yet
+we have no legal proof. We want you, Mr. Cole, to go out and get the
+evidence against Doctor Latham.”</p>
+
+<p>“Me?”</p>
+
+<p>“Why not? You are a detective, a very good one, though the fact
+isn’t generally known. If you find that Latham is guilty you will
+be more inclined to credit our statements and think favorably of
+the proposition we shall make you. You will leave here as you came,
+blindfolded and under guard. Until we understand each other better we
+don’t want you to learn too much about us. You will wish to sleep late
+in the morning, but to-morrow afternoon you can attack the Carmody case
+from a new angle.”</p>
+
+<p><span class="pagenum" id="Page_72">72</span></p>
+
+<p>“And my clients?” asked Cole.</p>
+
+<p>“You will be all the better able to serve them because of your
+connection with us. As soon as you have found your evidence against
+Latham, or learned enough to convince you that we are trustworthy, you
+will come here again and report. We shall find a way of communicating
+with you in due time. What do you say to the idea?”</p>
+
+<p>Cole pondered. He tried to analyze the situation, but all he could
+see were contradictions and perplexities. His only clear thought was
+that he had nothing to lose and perhaps much to gain by adopting the
+suggestion. His glance swept the circle of masked faces, all of them
+turned expectantly in his direction.</p>
+
+<p>“The idea is good,” he finally declared. “I shall pay my respects to
+Doctor Latham to-morrow afternoon.”</p>

+<div class="subheadc">DOCTOR LATHAM</div>
+</div>
+
+<p class="drop-cap">THE sun was several hours high the following morning when Kingdon Cole
+jumped out of bed and, from force of habit, turned toward his bathroom.
+A glance into the mirror on the white-tiled wall made him start.</p>
+
+<p>A man, even though he have nerves of steel and a constitution hard as
+armor, can’t pass through a siege of intense mental torture without
+showing traces of it. The nerve-racking agony, which Cole had undergone
+while lying on the cot, had left marks which seven hours of sound
+sleep had not removed. There was a suspicion of pallor beneath the
+bronze of his face. The usual brightness of his eyes was dimmed by
+a smoldering flicker which hinted at a long glimpse into infernal
+horrors. His face was drawn, and there were telltale lines and furrows.
+A twenty-four-hour growth of beard did not improve his appearance.</p>
+
+<p>“Nerves a bit on edge,” he told himself, turning away from the mirror.
+“Look as if I hadn’t slept a wink in a week. My landlady would tell me
+I need a doctor, but a shower and a shave will make me as chipper as a
+colt.”</p>
+
+<p>Whistling, he stepped into the tub and turned on the water. A few
+minutes of wriggling and writhing under the icy shower would remove all
+signs of his adventure. He thrilled to the first cold <span class="pagenum" id="Page_74">74</span>splash, and then
+Cole drew back from beneath the shower. His lips twisted slowly.</p>
+
+<p>“Guess I’ll try a doctor instead,” he decided. “I’m really in pretty
+bad shape. Nervous symptoms are not to be trifled with. I’ll see what
+Doctor Dickson Latham has to say about my condition.”</p>
+
+<p>Reluctantly he turned off the cold current and resigned himself
+to a lukewarm bath that did not refresh him in the least. Not too
+graciously, for habit becomes an exalted thing with men who live alone,
+he also decided to forgo his regular morning shave. It was best, he
+whimsically reflected, that Doctor Latham should see him at his worst.
+He dressed with less than his usual care, took in the bottle of milk
+and the newspaper that were always left at his door, and, before
+starting to prepare his own simple breakfast, poured out a saucerful of
+milk for “Toots.”</p>
+
+<p>Toots was a white-and-yellow cat who had slipped into his rooms one
+morning and made herself at home. Cole hadn’t had a word to say about
+the arrangement. He had been helpless before Toots’ firmness, and the
+cat had made herself a fixture in his establishment. With a languid
+indifference and an occasional feline shrug she permitted herself
+to be waited on by Cole, who at times wondered whether the cat was
+patronizing him. When Toots selected his softest pillow to sleep on and
+sunned herself on his writing desk beside the window Cole felt that the
+sanctity of his bachelor existence was being violated, but the cat’s
+blandly tyrannizing ways left him without a word of protest.</p>
+
+<p><span class="pagenum" id="Page_75">75</span></p>
+
+<p>After breakfast he called up Doctor Latham’s office and made an
+appointment for half past two. Then he sat down with his newspaper
+and pipe, the latter a smelly affair with a bowl shaped into the
+resemblance of a monkey’s face. It was an odd conceit, and it had
+been given him in lieu of his fee by an impecunious client. Only
+once had Cole had words with his landlady, and that was when the
+well-intentioned woman had undertaken to scrape out the bowl of his
+favorite pipe with a potato peeler. Cole smoked a weird mixture,
+compounded by himself of several domestic brands and spiced with a dash
+of perique. The strong concoction was a stimulant to mental effort, but
+at first he had hesitated to smoke such pungent stuff in the presence
+of the dainty Toots. The cat had not seemed to mind, however.</p>
+
+<p>He turned the pages of his newspaper, but found nothing that interested
+him. At length he threw the paper aside and refilled his pipe. Toots
+was sprawled out on the unfinished manuscript of an article on criminal
+tendencies which he was preparing for a psychological review. He gave
+the cat a reproachful glance, but said nothing. There were times when
+Toots seemed to go too far.</p>
+
+<p>He looked out into the warm sunlight that bathed Gramercy Park, but
+his thoughts were flitting in and out of a maze of rooms on the top
+floor of a skyscraper, located somewhere in the financial center. His
+recollections of the previous night were a queer medley of horror
+and mystery, of things that were terribly vivid and others that were
+dim and disconnected like a dream. Now, as he sat in the sunlight,
+<span class="pagenum" id="Page_76">76</span>leisurely smoking his pipe, he tried to picture the mystic circle in
+the dimly lighted room. He could not quite focus his mental vision on
+the scene; it was too shadowy and unreal. The seven masked faces melted
+into a blur, then faded away completely. It was no use trying to guess
+who those seven men were, or what their amazing conduct might mean.
+Perhaps his interview with Doctor Latham would suggest a solution to
+the mystery.</p>
+
+<p>The idea of approaching the doctor in the rôle of a patient had been
+something of an inspiration, but he had made no plans beyond that.
+The mock consultation would give him a chance to take the physician’s
+mental and physical measure and see what manner of man he was. Cole
+was a good judge of faces and a keen observer of human nature. To him
+the slightest gesture and the most casually spoken word had a meaning
+all their own. His first aim was to find out whether Latham was the
+kind of man who might commit such an atrocious crime as the operation
+on Malcolm Reeves; after that he would let his actions be guided by
+developments.</p>
+
+<p>Before starting for his appointment he thought it might be well to
+gather a few facts about the physician. He consulted his copy of “Who’s
+Who.” Dickson Latham was a specialist in nervous disorders, a graduate
+of several universities, a member of several learned societies, and his
+claim to distinction rested on his having written a number of treatises
+on cerebral surgery. The last fact seemed significant to Cole. He
+closed the book, <span class="pagenum" id="Page_77">77</span>gave Toots another mildly reproachful look, and went
+out to lunch.</p>
+
+<p>A few minutes before half past two he rang the doorbell of the old
+brownstone house in the Sixties, just east of Fifth Avenue, in which
+Doctor Latham resided and had his office. A young woman in the
+reception room handed him a magazine six months old and asked him to
+wait. Cole sat down and glanced about him out of the tail of an eye,
+while he pretended to look at the pictures in the periodical. It was
+a commonplace room, stuffily crowded with upholstered furniture. Two
+bookcases were filled with ponderous volumes in drab bindings. It was
+the typical reception room of a fairly thriving physician who derives
+most of his patronage from the neurotic and dyspeptic individuals of
+the upper middle class.</p>
+
+<p>After a brief wait Cole was facing the physician across a mahogany desk
+in the inner office.</p>
+
+<p>“What seems to be the matter?” asked Doctor Latham in a brisk, cheerful
+voice.</p>
+
+<p>“Nerves,” said Cole, making a lugubrious face. “No appetite. Can’t
+sleep nights. Always tired and out of sorts.”</p>
+
+<p>“Well, well, that’s too bad. You do look a bit run down, Mr. Stone. Let
+me see your tongue.”</p>
+
+<p>“Stone” was the name Cole had given over the telephone. It had seemed
+an unnecessary precaution, since Kingdon Cole was known to only a few
+people. His name seldom if ever appeared in connection with his work
+as a criminal investigator, but Cole always practiced discretion to a
+fault.</p>
+
+<p>While Doctor Latham looked at his tongue and <span class="pagenum" id="Page_78">78</span>felt his pulse Cole
+studied the physician closely, without appearing to do so. His first
+glance gave him a deep respect for the skill with which the surgeon
+of the night before had been made up. Doctor Latham was an inch or so
+taller, also a trifle thinner, and his black beard had the vitalic
+sheen that is not easily imitated; otherwise the resemblance was quite
+impressive.</p>
+
+<p>“Let me test your heart,” said the doctor, reaching for his stethoscope.</p>
+
+<p>Cole bared his chest. He was already beginning to suspect that he
+was chasing a fool’s errand. Doctor Latham did not seem capable of
+deliberate wrongdoing, to say nothing of a fiendish crime. In vain Cole
+searched his face for the faintest trace of duplicity. The physician
+had the perennial optimism and the bristling cheerfulness that, in
+cases of nervous disorders, are far more efficacious than pills and
+extracts. The very tone of his voice, together with his hearty laugh,
+acted as a stimulant on jaded nerves.</p>
+
+<p>“There isn’t anything the matter with you, Mr. Stone,” he declared when
+the examination was finished. “I can give you a tonic if you wish, but
+a couple of days’ rest will do you more good.”</p>
+
+<p>Cole buttoned up his shirt and replaced his collar. He felt certain now
+that his visit to the doctor’s office had been in vain. Latham’s kindly
+smile would have disarmed any suspicions remaining in his mind. It was
+a charming smile, a flash of white teeth against a setting of black
+beard, and it gave the final magnetic touch to a compelling personality.</p>
+
+<p>Cole chided himself for wasting valuable time, <span class="pagenum" id="Page_79">79</span>but he wished to make
+doubly sure before leaving the office. He wondered what would be the
+effect on the doctor if he should suddenly mention the name of Malcolm
+Reeves. None at all, very likely, he told himself; yet he felt an
+itching desire to make the test.</p>
+
+<p>He took out his pocketbook and looked questioningly at the doctor,
+meanwhile wondering how he might mention Reeves’ name in a casual, and
+yet sufficiently abrupt, manner to make the test conclusive.</p>
+
+<p>“Sit down, Mr. Stone,” said Doctor Latham, waving him to a chair. “You
+interest me. What is your profession?”</p>
+
+<p>“Author,” said Cole, recalling that he had two volumes on criminology
+to his credit.</p>
+
+<p>“Ah! And what do you write?”</p>
+
+<p>“Trifling things,” said Cole modestly. “You probably never saw any of
+them. Such frivolous reading matter wouldn’t interest you.”</p>
+
+<p>“I read very little. The medical journals and a glance at the
+newspapers are about all I find time for. Do you know, Mr. Stone, that
+you puzzle me considerably?”</p>
+
+<p>“Indeed!” said Cole absently, still wondering how he might precipitate
+Malcolm Reeves’ name into the conversation.</p>
+
+<p>Doctor Latham smiled genially. A question kept teasing Cole’s mind.
+What would be the effect on that beaming countenance if he should
+suddenly speak Malcolm Reeves’ name? Probably none whatever, he once
+more told himself; but the thought continued to tantalize him.</p>
+
+<p><span class="pagenum" id="Page_80">80</span></p>
+
+<p>“There is a type of neurasthenic that is known to every medical
+practitioner,” the doctor went on. “Their symptoms are quite well
+defined. Their ailments are mostly imaginary. On the slightest pretext
+they will run to a physician with a long tale of woe. The physician
+in most instances, gives them a little sympathetic advice, a harmless
+tablet made up of sugar and dough, and pockets his fee. There’s nothing
+else to do. If told that their troubles exist only in their imagination
+they get offended and run to another doctor. Personally I don’t care
+for that kind of patients. Now, Mr. Stone, you don’t belong to that
+type. You are not a neurasthenic, far from it. I wish I had your
+nerves.”</p>
+
+<p>Cole regarded him with a questioning look.</p>
+
+<p>Doctor Latham laughed pleasantly. “You’re in perfect condition, Mr.
+Stone. Perhaps you have smoked too much, or taken too much strong
+coffee in the last few days, resulting in one or two sleepless nights,
+but there is nothing else the matter with you. Ordinarily you would
+have shaken off the effects with a cold shower, or a hike in the
+country. I dare say you haven’t consulted a physician more than two or
+three times since you grew up. Under the circumstances I am somewhat
+curious to know why you came to me.”</p>
+
+<p>Cole gave him a sharp glance, but the affably smiling face instantly
+quieted the misgivings which the doctor’s statement had aroused.</p>
+
+<p>“What I don’t see,” Latham went on, “is why you went to a doctor at
+all, and why to me in particular. We never saw each other until to-day.
+I don’t flatter myself by thinking that you knew me <span class="pagenum" id="Page_81">81</span>by reputation.
+People who have no regular physician usually go to some one recommended
+to them by friends. They don’t like to consult a doctor who is an utter
+stranger to them. Perhaps among my patients there is a friend of yours
+who mentioned me to you?”</p>
+
+<p>“That’s it exactly,” said Cole, thrilling inwardly as he saw his chance
+to pitch Reeves’ name into the conversation. “Only the other day I was
+complaining to a friend of not feeling well, and he suggested I go to
+you. His name——”</p>
+
+<p>“Ah,” asked Doctor Latham, speaking in very soft tones. “I wonder if
+you are referring to Malcolm Reeves?”</p>
+
+<p>For a moment Cole looked as if he had received a blow between the
+eyes. He gathered himself in an instant, but not before the doctor had
+noticed his surprise. The physician was still smiling, but now the
+smile was different. It was frosty and pale. “I see I guessed right,”
+he murmured.</p>
+
+<p>“Is Reeves one of your patients?” Cole managed to ask.</p>
+
+<p>The doctor leaned back in the chair, crossed his long legs, and gazed
+toward the ceiling. Cole became conscious of a distinct chill in the
+air, and he felt irritated at himself for having stumbled into the same
+trap he had set for the physician. Doctor Latham, he was beginning to
+perceive, was a man whose mental thrust was as quick and sure as his
+own.</p>
+
+<p>“Frankness is an excellent policy, Mr. Stone,” observed the physician
+coldly. “We shall make better progress if you will put all your cards
+on the <span class="pagenum" id="Page_82">82</span>table. You did not come here to consult me about your health.
+May I ask why you are honoring me with this visit?”</p>
+
+<p>“You have not yet answered my own question,” observed Cole, quickly
+rallying to the verbal fencing match. “Is Reeves a patient of yours?”</p>
+
+<p>The doctor lowered his gaze. His piercing eyes searched Cole’s face. A
+faint flash of white teeth showed between the bearded lips.</p>
+
+<p>“I believe that question has a point to it,” he observed. “You ought to
+know, Mr. Stone, that a physician never discusses his patients. It is
+a very good rule, especially in the present instance. It affords me a
+good excuse for not answering your question.”</p>
+
+<p>“Then you admit you found the question embarrassing?”</p>
+
+<p>“A discreet man never admits anything, Mr. Stone. I may point out,
+however, that questions are never embarrassing, although answers
+sometimes are. I believe Wilde says something to that effect in one of
+his plays.”</p>
+
+<p>“Then you positively decline to answer?”</p>
+
+<p>“In order to spare us mutual embarrassment, yes. You see, Mr. Stone,
+there are circumstances in which a truthful answer may convey an
+erroneous impression. Now, won’t you tell me to what I owe the honor of
+this visit?”</p>
+
+<p>“Is that a candid question, Doctor Latham?”</p>
+
+<p>“By no means, my friend. I knew the answer before I spoke the question.
+I was merely curious to see whether you would reply truthfully.”</p>
+
+<p><span class="pagenum" id="Page_83">83</span></p>
+
+<p>Cole smiled. It was evident that Doctor Latham was a past master in the
+art of dueling with words. The man’s frankness amazed him. In admitting
+that he knew the purpose of Cole’s visit he had also admitted that he
+knew something about Malcolm Reeves’ condition. But he had turned his
+phrases so adroitly that nothing of a tangible nature could be fastened
+on him.</p>
+
+<p>“Will you tell me how you knew, doctor?”</p>
+
+<p>“Through a process of elimination. I knew at first glance that your
+concern over your physical condition was only a subterfuge. That
+narrowed the range of speculation down considerably. In fact, it left
+only one possible theory in regard to the object of your visit.”</p>
+
+<p>“Why only one? Isn’t it conceivable, for instance, that I came here to
+see if your office contains anything worth stealing?”</p>
+
+<p>Doctor Latham shook his head. “You don’t look the part, Mr. Stone.”</p>
+
+<p>“Well, suppose I am an officer of the law and came here to see if you
+are prescribing illegal amounts of intoxicating liquor or habit-forming
+drugs?”</p>
+
+<p>“You didn’t go about it the right way.”</p>
+
+<p>“Couldn’t I be a long-lost friend or relative?”</p>
+
+<p>“I haven’t either. You came here for one specific purpose, Mr. Stone,
+and I know what that purpose is.”</p>
+
+<p>Cole regarded him narrowly. “Knowledge sometimes implies guilt,” he
+remarked in casual tones.</p>
+
+<p>“But not always. You think that, because I know the object of your
+visit, I have guilty knowledge <span class="pagenum" id="Page_84">84</span>of a certain matter that you are
+interested in. That’s a very loose inference, Mr. Stone.”</p>
+
+<p>Cole thought for a few moments. The other’s indirect frankness amazed
+him, yet Doctor Latham was entirely too slippery to permit himself to
+be pinned down to hard facts.</p>
+
+<p>“Each of us seems to have come to stalemate,” observed the physician
+after a pause. “Shall we call the game a draw? Both of us have gained
+something. You think you have verified a suspicion, while I have
+learned to be on my guard against a new source of possible danger. Why
+not leave well enough alone?”</p>
+
+<p>“It’s a good suggestion,” said Cole, smiling. “Thanks for a very
+interesting half hour, doctor. Good day.” He bowed and moved toward the
+door, but the doctor’s voice made him turn back.</p>
+
+<p>“Just one moment, Mr. Stone. I think you have forgotten something. My
+fee is ten dollars. Ah, thank you!”</p>

+<div class="subheadc">COLE RECEIVES A WARNING</div>
+</div>
+
+<p class="drop-cap">HE left the physician’s office a poorer, but a wiser, man. The half
+hour had been well spent even though the interview had yielded little
+in the way of tangible results. Cole had met an interesting personality
+and come in contact with a fine-edged mind. The doctor, with his
+subtleties and his evasions, had proven a fascinating character. His
+depth and elusiveness carried a teasing appeal to Cole’s imagination.
+Cole was not yet through with Doctor Latham.</p>
+
+<p>He walked to the corner, turned into a tobacconist’s shop, and bought
+a package of cigarettes, then stood at the curb and smoked one, while
+he glanced now and then at the physician’s house. The drab brownstone
+façade seemed as mocking and tantalizing as the man who dwelt within.
+It was as baffling and impenetrable as the doctor himself. Cole tried
+to analyze his impressions, but it was a hard task. The physician had
+admitted nothing except by implication. He had thrown out certain bold
+hints, and then he had practically challenged Cole to make the most of
+them.</p>
+
+<p>Cole did not like to draw hasty conclusions, but, after he had sifted
+down his impressions, there remained in his mind a picture of a
+polished and very artful rogue who performed his machinations with an
+adroit touch and a high degree of finesse. The picture was blurred
+in spots, and he had to <span class="pagenum" id="Page_86">86</span>use his imagination to touch up the obscure
+parts. It was significant, however, that the surgeon’s make-up should
+have exerted such a startling effect on Malcolm Reeves the night
+before. Beyond doubt Reeves had thought that he recognized the man who
+was responsible for his pitiful state. This proved inferentially Doctor
+Latham was the man who——</p>
+
+<p>But Cole did not like to deal in inferences. They were treacherous
+things, as he had observed on numerous occasions. He must have more
+facts before he began building up theories on the flimsy foundation
+which Doctor Latham’s oily innuendos had created in his mind. Meanwhile
+it was interesting to note that the clew which he had brought with him
+from the circular table appeared to be a substantial one. He had not
+convinced himself of Doctor Latham’s guilt, but he had at least found
+a promising lead. Reluctantly, for his experience of the night before
+still rankled, he was forced to admit that there was a modicum of truth
+in what the spokesman had told him.</p>
+
+<p>He finished his cigarette and was about to turn away, but just then a
+figure, rounding the opposite corner, claimed his attention. With a
+little start he recognized Professor Carmody. Bending over a stout cane
+the professor walked with a jerky gait and the plopping sound of shoes
+several sizes too large. He wore a sun-bleached silk hat and, despite
+the balmy autumn weather, a long overcoat covered his gaunt form.
+Cole nodded in a knowing way as he saw the professor turn into Doctor
+Latham’s house.</p>
+
+<p><span class="pagenum" id="Page_87">87</span></p>
+
+<p>Thoughtfully he walked away. His suspicions and speculations were
+assuming tangible form. Professor Carmody’s visit to Latham’s house
+in broad daylight suggested several things. Viewed in connection with
+certain other circumstances, it hinted strongly at a bond of interest
+between the two men. In view of what Cole already knew it seemed not
+so very far-fetched to suppose that they were associates in some
+enterprise that was more or less closely related to Malcolm Reeves’
+fate. That Carmody should openly call on the doctor seemed to indicate
+that the conspirators felt that they had covered their tracks so
+carefully that ordinary precautions could be thrown to the wind.</p>
+
+<p>Cole cut through a corner of the park, and gradually his perplexities
+dissipated themselves in the soft autumnal haze that hung over the
+greenery. He knew how to loaf as well as to work, and he possessed the
+happy knack of forgetting his problems in contemplation of rippling
+waters, or an azure sky. It was thus he conserved his energies and kept
+in touch with the softer aspects of life.</p>
+
+<p>He rested for half an hour, and then he remembered he had a duty to
+perform. It was not a pleasant task, but it must be done. Now that
+he had learned something definite about Malcolm Reeves’ fate, it was
+necessary that he should report progress to his clients. As he retraced
+his steps across the park and turned north on Fifth Avenue he wondered
+how much it would be advisable to tell. To go into details in regard
+to his adventures of the previous night would be impossible, for Cole
+himself did not know what they meant.</p>
+
+<p><span class="pagenum" id="Page_88">88</span></p>
+
+<p>Ascending the steps of a square-cornered house of gloomy aspect he rang
+the doorbell. There was a tomblike air about the residence of Hector
+Englebreth that gave Cole a chill each time he visited the house. Out
+of deference to the whims of the invalid who occupied it the window
+shades were nearly always lowered. Doors turned without the faintest
+sound on well-oiled hinges. Heavy carpets muffled the footfalls of
+inmates and visitors. The heavily shaded lamps threw a subdued light on
+massive and somberly upholstered furniture that seemed to belong to a
+remote past.</p>
+
+<p>A tight-lipped manservant ushered Cole into the library. Englebreth
+was seated in a wheel chair before a desk of black walnut. Despite the
+infirmity, which an acute case of inflammatory rheumatism had brought
+him, his long and triangular face gave an impression of wiry strength.
+His shoulders, as he sat hunched in the wheel chair, seemed uncommonly
+broad. His face was bloodless; his short-cropped, upstanding hair was
+almost white. Except when he spoke, the long, thin lips were tightly
+compressed, making him look as though he were constantly exerting his
+will power to hide the signs of his suffering.</p>
+
+<p>“Any news, Mr. Cole?” he inquired in a low, toneless voice.</p>
+
+<p>“I have made some progress,” replied Cole, also speaking in subdued
+tones. In that dim, somber room it seemed natural to speak softly. “I
+have reason to believe that your brother-in-law is still alive.”</p>
+
+<p>Englebreth had been tapping the desk with a pencil. <span class="pagenum" id="Page_89">89</span>Suddenly the
+tapping stopped. He gazed fixedly at the detective. “How much reason?”
+he asked.</p>
+
+<p>“I know it to be a fact,” said Cole, weighing his words, “that Mr.
+Reeves was alive last night.”</p>
+
+<p>“So,” mumbled the other in tones scarcely above a whisper. “Professor
+Carmody hasn’t done away with him, then. I feared that he might——” He
+broke off, then raised his voice a little. “How do you know this, Mr.
+Cole? How can you be so positive that my brother-in-law was alive last
+night? You don’t mean to say that you have seen him?”</p>
+
+<p>The last sentence was spoken in tense and vibrant tones, so unlike
+Englebreth’s usually colorless voice.</p>
+
+<p>“Before I answer that question,” said Cole, “I want to ask you one.
+What makes you so positive that Professor Carmody has had a hand in
+your brother-in-law’s disappearance?”</p>
+
+<p>“Have you learned something that has brought you to a contrary view?”</p>
+
+<p>“Please answer my question.”</p>
+
+<p>A scowl darkened Englebreth’s face. He resumed his slow tapping with
+the pencil. “We know that my brother-in-law had frequent and secret
+meetings with Carmody. We have established definitely that he had an
+appointment with the professor on the night of his disappearance.
+One of the servants in his house heard him make the appointment over
+the telephone. You yourself learned, from the delicatessen keeper
+across the street from Carmody’s place, that a man answering Malcolm’s
+description entered the house on that particular night. Fairly
+conclusive, I should say.”</p>
+
+<p><span class="pagenum" id="Page_90">90</span></p>
+
+<p>Cole eyed him levelly. “You are holding something back, Mr. Englebreth.
+You have not stated your principal reason for suspecting Carmody in
+connection with Mr. Reeves’ disappearance.”</p>
+
+<p>The tapping became a furious tattoo. “Why do you say that, sir?”</p>
+
+<p>Cole fumbled for words, then laughed. “I’ll be hanged if I know! It’s
+nothing but a hunch. From the first I had a feeling that you were not
+telling me all, but I admit I had no sound reason for thinking so.”</p>
+
+<p>Englebreth, seemingly mollified, smiled. “You detectives are suspicious
+of everybody. I suppose that’s a part of your stock in trade. However,
+I don’t mind admitting that, in this instance, you were partly right.
+I have told you everything that can be of any help to you in your
+search for Malcolm; yet there are certain trifling details that, for
+private reasons and out of regard for the family, I have not confided
+to you. You would not be interested in them, and they couldn’t be of
+any possible use to you. It was because of these private and delicate
+matters that I took the case to you instead of the police. Now will you
+answer my question? Have you seen Malcolm?”</p>
+
+<p>“I have, Mr. Englebreth. I saw him last night.”</p>
+
+<p>“Where?” The invalid strained forward in his chair. “In Professor
+Carmody’s house?”</p>
+
+<p>“No; I have not yet seen the inside of the professor’s residence.”</p>
+
+<p>“Then where did you see him?” The tapping had ceased again, and
+Englebreth was waiting breathlessly for the answer.</p>
+
+<p><span class="pagenum" id="Page_91">91</span></p>
+
+<p>“That’s the queer part of it.” Cole gave a little baffled laugh. “I
+have seen your brother-in-law, but I can’t tell you where.”</p>
+
+<p>“You can’t?”</p>
+
+<p>“Because I don’t know.”</p>
+
+<p>A threatening look crossed Englebreth’s face. “This is no occasion
+for jests, Mr. Cole. Even if you have no feelings of your own in the
+matter, you ought to respect the sentiments of other people. My wife is
+deeply shocked over the uncertainty regarding her brother’s fate.”</p>
+
+<p>“Pardon me, Mr. Englebreth. I laughed, but it was only out of sheer
+bewilderment. I had an experience last night that was so unbelievable
+that I shan’t try to describe it. I feel dazed whenever I look back
+upon it. All I can tell you is that I saw Mr. Reeves alive.”</p>
+
+<p>“And well?” questioned Englebreth sharply.</p>
+
+<p>“He seemed to have been through a trying experience.”</p>
+
+<p>“You are quibbling. I want the truth.”</p>
+
+<p>“Perhaps I shall be able to give it to you some time within the next
+twenty-four hours. For the present I fear you will have to be satisfied
+with what I have told you. My impressions of what I saw and heard last
+night are not very clear. You will understand the reason when I give
+you a full report.”</p>
+
+<p>“This is strange talk, Mr. Cole.”</p>
+
+<p>“Not half so strange as some of the things that happened to me last
+night.”</p>
+
+<p>Englebreth sat erect in his chair, regarding the detective with a
+piercing gaze. Evidently he was <span class="pagenum" id="Page_92">92</span>far from satisfied, and Cole could not
+blame him. Silence fell between them; then a soft tinkling was heard.
+Even the telephone seemed to utter its summons in whispers in that
+house of subdued sounds.</p>
+
+<p>The invalid wheeled his chair a little closer to the desk and put the
+receiver to his ear. A conversation ensued, and gradually Englebreth’s
+face underwent a transformation. Cole could not interpret the new look
+that came into his countenance, but he watched it in wonder. In a few
+minutes the invalid hung up, and the puzzling expression left his face
+as suddenly as it had come. He was smiling when he turned to Cole.</p>
+
+<p>“On the whole I find your report quite satisfactory,” he said in
+conciliating tones. “I appreciate the difficulties you have to deal
+with. Don’t mind me if I seem impatient. May I expect to hear from you
+soon again?”</p>
+
+<p>“To-morrow, I hope.” Cole was still marveling at the change he had
+witnessed in his client. He wondered whether the telephone conversation
+had brought it about. From Englebreth’s part in it he had been unable
+to make out its nature, but he imagined that his client had received
+news of a startling kind. After an exchange of a few casual remarks he
+got up and moved toward the door.</p>
+
+<p>“Just one thing more, Mr. Cole,” said Englebreth as he placed his hand
+on the knob. “Please be careful.”</p>
+
+<p>“What?” Cole turned and looked back at the invalid. The tone, rather
+than the words, had given him an odd sensation. Englebreth’s white face
+was <span class="pagenum" id="Page_93">93</span>wreathed in smiles, but Cole sensed a hidden barb somewhere.</p>
+
+<p>“Just be careful,” said the invalid. “That’s all, Mr. Cole.”</p>
+
+<p>Cole went out, but echoes of Englebreth’s voice pursued him through
+the door and out on the street. The words had sounded as though they
+contained a veiled threat of some kind. What could he have meant? He
+turned the question over in his mind, time and again. Was it possible
+that Englebreth, in some strange and devious way, had learned of the
+attempt that had been made to persuade Cole to betray his client?</p>
+
+<p>The theory seemed grossly improbable, but, as he walked along, he
+could think of no other solution. The more he thought of it the more
+likely it seemed that his client had, in some mysterious manner, got
+an inkling of last night’s happenings. He remembered the agitation he
+had shown at the telephone. And later, when he gave Cole that peculiar
+warning, his voice had sounded as though he meant to convey a threat of
+terrible punishment if the detective should go back on his duty.</p>
+
+<p>Cole had not walked far when his step began to lag. He paused at a
+corner and glanced at his watch. He pursed his lips, then he scowled a
+little, and a look of weighty responsibility came into his face.</p>
+
+<p>It was time to go home and feed Toots.</p>

+<h2 id="chap_VIII">CHAPTER VIII</h2>
+<div class="subheadc">THE UNKNOWN SEVEN</div>
+</div>
+
+<p class="drop-cap">ALL evening Cole had felt a presentiment that his telephone was to
+ring. When it finally did ring, shortly after eleven o’clock, he knew,
+even before he lifted the receiver from the hook, that he was about to
+receive a message from the mysterious seven.</p>
+
+<p>His “hello” was answered by the rich soprano voice of the woman who
+called herself Miss Brown, but somehow it sounded different. The
+frolicsome undertone, which he had noticed the previous evening, was
+gone. In place of it there was a faint tremor that hinted of keen
+anxiety.</p>
+
+<p>“I am calling from a public booth near Madison Square,” she told
+him. “At exactly twelve o’clock I shall be waiting in my car, on the
+southeast corner of Broadway and Twenty-third Street.”</p>
+
+<p>“I’ll be there,” said Cole firmly. During the late afternoon and
+evening he had made up his mind that, if a summons should come from the
+mysterious seven, he would obey it.</p>
+
+<p>“But be careful,” she went on, and the last word had an oddly familiar
+sound in Cole’s ears. “An attempt will be made to follow you.”</p>
+
+<p>“I know,” said Cole lightly. “I’ve been watched ever since I went out
+to dinner this evening. I believe somebody is looking up at my windows
+this very moment. Have no fear. I’ll shake him off.”</p>
+
+<p>Again requesting him to be careful, Miss Brown rang off. For a moment,
+after the connection had <span class="pagenum" id="Page_95">95</span>been severed, he stood smiling into the
+transmitter. Then he stepped to the window and looked out into Gramercy
+Park. The sky was partly overcast, and a haze of moonlight and shadows
+hovered over the trees. Almost directly below his window stood a gaunt
+individual whose eyes were slanting up at him beneath the brim of a
+dark felt hat.</p>
+
+<p>Cole examined his pistol before he put it in his pocket, donned hat and
+light overcoat, and went out. On the stoop he paused for a moment and
+stuck a cigarette between his lips. Then he swung down the steps and
+sauntered up to the watcher at the curb.</p>
+
+<p>“Pardon,” he said urbanely. “Could I trouble you for a match?”</p>
+
+<p>The watcher searched his vest pocket and handed him one. Cole caught
+a full view of the fellow’s face as he kindled his cigarette. The man
+was a stranger to him. Murmuring profuse thanks for the accommodation
+Cole walked away. Twenty minutes later, after a devious journey by
+foot, subway, and surface cars, he plunged into the traffic jam in the
+theatrical district. For a little while he darted in and out among
+surging streams of humanity. Then, certain that he had thrown the
+pursuer off his tracks, he boarded a southbound car. A tower clock was
+signaling the midnight hour just as he reached the appointed corner in
+Madison Square.</p>
+
+<p>“You are very prompt,” observed Miss Brown, as he stepped into the
+limousine in which his adventure had begun, exactly twenty-four hours
+ago. “You are sure you haven’t been followed?”</p>
+
+<p>“Only a short distance.” Cole sat down beside <span class="pagenum" id="Page_96">96</span>her, having a weird
+feeling that ages had passed since he last touched those cushions. “I
+shook off the fellow quite easily.”</p>
+
+<p>The car was gliding swiftly toward the south, but soon it began to turn
+and twist in all directions. The windows were shaded, and Cole could
+only guess which way they were going.</p>
+
+<p>“You’re an audacious person,” murmured the girl. “After what happened
+last night I wasn’t sure you would come with me a second time.”</p>
+
+<p>Cole smiled. “Audacious isn’t quite the word.”</p>
+
+<p>“No, I suppose not. You’re not the kind of man who indulges in foolish
+bravado. Your decision to come with me to-night was the result of long
+and careful thinking, after you left Doctor Latham’s office. Your
+interview with the doctor convinced you that our acquaintance might
+be worth cultivating, despite the rough treatment you were given last
+night. Am I right?”</p>
+
+<p>“In the main. You know, then, that I called on Doctor Latham?”</p>
+
+<p>“Of course. You have been under constant surveillance since you left
+our establishment early this morning.”</p>
+
+<p>“How flattering! But you puzzle me, Miss Brown. I have been conscious
+of being watched only since dinner time.”</p>
+
+<p>She gave an amused laugh. “One is never conscious of our brand of
+espionage. We have men on our staff who have reduced shadowing to a
+fine art. They are not so easily shaken off as was the simpleton who
+stood outside your windows this evening. By the way, Mr. Cole, aren’t
+you harboring <span class="pagenum" id="Page_97">97</span>a little resentment against me for my part in last
+night’s affair?”</p>
+
+<p>“Perhaps,” said Cole dryly, “but curiosity is a stronger motive than
+resentment.”</p>
+
+<p>“You are not at all gallant. Lots of other men would have replied to
+that question with a flowery compliment.”</p>
+
+<p>“They would have been fools. You would have secretly despised them for
+it.”</p>
+
+<p>A little pause. “Thank you,” she whispered, but the words sounded so
+faint that Cole was not sure he was expected to hear them.</p>
+
+<p>The car had ceased its zigzagging course and was traveling in a
+straight line. Presently Miss Brown produced the scarf with which she
+had covered his eyes the previous night.</p>
+
+<p>“I hope this is the last time I shall have to blindfold you,” she
+murmured, as she folded the cloth into a bandage and covered the upper
+portion of his face. “Perhaps the next time——”</p>
+
+<p>She did not finish the sentence. Just then the car stopped, and she
+guided him across the sidewalk and up the stone steps. In a few moments
+they were darting upward in the elevator. Again the wall opened at Miss
+Brown’s touch on a hidden spring. As it closed behind them Cole had
+a hazy feeling of being shut off from the world. They walked a short
+distance down the corridor. Then a door opened, and once more he found
+himself in the room with the circular table. The girl vanished, and a
+voice bade him step forward.</p>
+
+<p>He walked up to the table. The masked men seated around it looked gray
+and ghostly in the <span class="pagenum" id="Page_98">98</span>dusk. He scanned the veiled faces closely as his
+eyes responded to the dim light. The black beard was not there; yet he
+counted seven faces. Evidently the surgeon was not wearing his disguise
+to-night.</p>
+
+<p>“Very glad to see you, Mr. Cole,” said a voice which he recognized.
+“The fact that you have returned is additional proof that we were not
+mistaken in you. Sit down.”</p>
+
+<p>Cole seated himself at the spokesman’s side. His ears were keyed to
+catch any suspicious sound, while his eyes cautiously explored the dusk
+about him. His right hand hung loosely over the side of the chair, but
+it was ready to reach for his pistol at the slightest sign of danger.
+He was far from certain in regard to the intentions of the seven men,
+and he was determined not to be caught off his guard.</p>
+
+<p>“Perhaps it will give you some satisfaction to know,” the spokesman
+went on, “that you sent one of our men to the hospital last night.”</p>
+
+<p>Cole smiled faintly as he recalled the fight in the dark. His knuckles
+still showed bruises from the blows he had showered on his opponent
+before he was overwhelmed by superior numbers.</p>
+
+<p>“He is a big, husky chap, and he knows how to put a lot of steam into
+his punch,” the spokesman continued. “You pounded his face to a jelly.
+I don’t think Sam will ever get over the humiliation. His mortification
+ought to soften the bitterness you naturally feel toward us. By the
+way, you called on Doctor Latham, as I suggested. Did the interview
+prove satisfactory?”</p>
+
+<p><span class="pagenum" id="Page_99">99</span></p>
+
+<p>“It wasn’t conclusive,” said Cole guardedly.</p>
+
+<p>“We didn’t expect that. The doctor is too wily to permit himself to
+be caught so easily. But didn’t your talk with him leave a strong
+presumption of guilt in your mind?”</p>
+
+<p>“It convinced me that Doctor Latham knows something of what happened to
+Mr. Reeves.”</p>
+
+<p>“And to that extent it modified your skepticism in regard to us?”</p>
+
+<p>“I am here,” said Cole with a shrug. “Isn’t that answer enough?”</p>
+
+<p>“It is. You wouldn’t have come back to-night unless something had
+happened to counteract the bad impression which you derived from your
+first visit. No doubt the balance is still against us, but you are
+willing to listen to what we have to say. Will you pay close attention
+while I state a hypothetical case?”</p>
+
+<p>“My ears are wide open.”</p>
+
+<p>“Very well, then. First let me state a general principle. It must have
+occurred to you, Mr. Cole, that there is something radically wrong with
+the enforcement of our laws and the administration of justice. The
+jails are doing a thriving business, and many criminals are convicted
+every day in the year. With rare exceptions, however, they are the
+smaller fry. Too often the big rascals go unpunished, while the little
+fellows get it in the neck. The agencies of law and order are often
+powerless when dealing with criminals who perpetrate their malefactions
+on a large scale. Are you with me so far?”</p>
+
+<p>“Go on,” said Cole.</p>
+
+<p><span class="pagenum" id="Page_100">100</span></p>
+
+<p>“The cause of this deplorable situation is obvious. The big rascal
+evades the law and goes scot-free, while the little fellow breaks the
+law and lands in jail. Or else the big rascal violates the law in such
+a clever manner that conviction is impossible. He has the best legal
+talent on his side. Brilliant and unscrupulous lawyers lie awake nights
+scheming how a powerful client might commit crimes with impunity. Often
+the big rogue has unlimited resources at his command. If he is in
+danger of getting caught a substantial bribe frequently lets him out,
+or he uses political or social influence to get clear of the danger.
+True, isn’t it?”</p>
+
+<p>“Unfortunately it is,” said Cole, “but I don’t see what all this——”</p>
+
+<p>“Just a moment. I am getting to the point as fast as I can. You
+must have noticed that the police and other agencies are seriously
+handicapped in trying to cope with crime on a large scale. They are
+hampered by a number of things, inefficiency, corruption, political
+patronage, sometimes indifference on the part of the public. There are
+many honest and capable men among them, but their number is too small.
+Besides, the machinery of justice is too ponderous and cumbersome. In
+its competition with crime it has the same handicap as a truck trying
+to compete with a roadster. But that isn’t the worst of it.”</p>
+
+<p>“You’re painting a gloomy picture,” Cole observed.</p>
+
+<p>“But you know as well as I do that it is true to life. The most serious
+phase of the situation is the fact that the law, in effect if not
+in theory, is <span class="pagenum" id="Page_101">101</span>punitive rather than preventive. Our administrators
+of justice are too often content with locking the stable after the
+horse is gone. It may be a satisfaction to you, when your pocketbook
+is stolen and the money squandered, to see the thief go to jail, but
+it isn’t doing you any material good. It may be gratifying to you to
+know that that particular thief won’t steal any more pocketbooks for a
+while, but that isn’t going to compensate you for your loss. The time
+to stop the crook is before the damage is done, and that’s exactly
+where our police system falls down on the job.”</p>
+
+<p>“True enough,” Cole admitted. “But what are you going to do about it?”</p>
+
+<p>He fancied the spokesman was smiling, but he could not be sure. The
+others at the table had not spoken a word.</p>
+
+<p>“There is the Carmody case, for instance,” the other went on, without
+answering Cole’s question directly. “It shouldn’t be called that, for
+the professor is only a puppet, a dwarf in comparison with the men who
+are pulling the strings. You have barely scratched the surface of the
+case, so, no doubt, you are amazed at what I say. The so-called Carmody
+case is in reality one of the biggest swindles ever projected. It is
+being engineered by a group of brilliant and very powerful men who have
+enormous resources in brains and cash at the tips of their fingers.
+They are working in the dark, with the utmost secrecy and astounding
+cleverness. If the authorities at Washington knew what was going on,
+there would be a panic all along Pennsylvania Avenue.”</p>
+
+<p><span class="pagenum" id="Page_102">102</span></p>
+
+<p>“Why doesn’t some one tell them?”</p>
+
+<p>The spokesman chuckled deprecatingly. “If I should go to them with the
+story to-morrow they would demand proof, and I haven’t any. That is,
+nothing that is tangible. I am positive of my facts, but proving them
+is another matter. In a case like this the proof can’t be produced
+until the damage is already done. Having no evidence, I should probably
+be met with indifference or skepticism. Even if an investigation were
+made, it would be purely perfunctory. The investigators would kick up
+just enough dust to blind themselves and tip the conspirators off to
+their danger.”</p>
+
+<p>“But, if things are as bad as you say, something should be done.”</p>
+
+<p>“Something is being done, Mr. Cole, and that brings me to the
+hypothetical case I was about to state. Imagine a group of wealthy
+and public-spirited citizens, men of brains, aggressiveness, and
+imagination, who have banded themselves together for the purpose of
+correcting the condition I have just described. Let us say they have
+built up a small, compact and marvelously efficient organization, in
+comparison with which the government’s ponderous machinery is like
+the truck trying to out-distance the roadster. This organization,
+unhampered by graft, political patronage, and red tape, and having
+unlimited resources at its command, becomes the secret ally of the
+police, the department of justice, and similar agencies. Its existence
+is practically unknown to all but its own members. Like the criminal
+whom it is endeavoring to combat, it works in the dark and silently.
+This in itself <span class="pagenum" id="Page_103">103</span>gives it a tremendous advantage. You are beginning to
+understand?”</p>
+
+<p>Cole nodded.</p>
+
+<p>“This organization has a corps of brilliant operatives, each one tested
+and tried and found one hundred per cent honest and efficient. At its
+head is an executive of exceptional ability. All the resources of the
+organization are placed at his disposal. He is paid a salary so large
+that it should render him immune to all sorts of corruption and amply
+compensate him for the fact that his achievements never become known to
+the outside world.”</p>
+
+<p>“For a time all goes well. Now and then the police, or the authorities
+at Washington, receive a package from an anonymous source. They open
+it and dazedly peruse the contents. It is evidence gathered by some of
+the shrewdest detectives in the country and put into shape by the best
+lawyers obtainable. It is so thoroughly prepared that it will stand
+every legal test. All the authorities have to do is to hale the culprit
+into court and read the evidence to the jury. In all cases but one the
+verdict has been guilty.”</p>
+
+<p>“The exception,” the spokesman went on in gritty tones, “was due to
+the dereliction of the executive at the head of the corps. Contrary to
+expectations and despite all the incentives which he had for remaining
+loyal to the organization, the man was corrupted by the other side. No
+doubt he sold his honor for a fortune. At all events he disappeared,
+and the case collapsed. It was necessary to find some one to take
+his place. This time the men at the head of the organization were
+determined to <span class="pagenum" id="Page_104">104</span>make no mistake. The next executive must be not only
+efficient and fearless, but incorruptible as well. For once the leaders
+decided to let the ends justify the means and go the limit in testing
+their candidate. Well, they did go the limit. They tried him in acid,
+and he assayed twenty-four carats.”</p>
+
+<p>Murmurs of approval went around the circle. Every face was leveled
+intently in Cole’s direction. For several minutes he had anticipated
+the trend of the spokesman’s remarks, yet he started a little at the
+last sentence.</p>
+
+<p>“Now you understand,” the other continued. “For some time we have been
+satisfied in regard to your ability. Our secret investigation left
+us in no doubt on that point. Last night we learned that you could
+resist three of the most powerful forms of temptation imaginable—fear,
+greed, and a charming woman’s tears. And not only that, but you also
+proved your superiority in a physical encounter, in addition to showing
+presence of mind and quickness of wit in a most terrifying situation.
+You scored one hundred per cent on every point. I am only sorry the
+test had to be so severe.”</p>
+
+<p>Cole sat silent for a time; then he shook the spokesman’s outreached
+hand. “It’s worth a lot to me to know that I am a twenty-four-carat
+man,” he declared.</p>
+
+<p>“Then you accept?”</p>
+
+<p>Cole pondered while his glance swept the masked faces.</p>
+
+<p>“Who are you?” he asked.</p>
+
+<p>“We call ourselves The Unknown Seven. The name fits because nobody, not
+even our best friends, <span class="pagenum" id="Page_105">105</span>know us in our capacity of secret allies of the
+authorities. It’s possible you have seen some of us before.”</p>
+
+<p>He raised his arm, and each man at the table made a sudden motion
+with his hand. In an instant the seven masks had been removed. Then a
+glaring light shattered the dusk, and Cole looked in astonishment at
+the unveiled faces. Several of them were familiar to him from pictures
+that had appeared in the newspapers, in connection with weighty
+national or municipal affairs. He blinked his eyes in bewilderment and
+was about to say something when the door suddenly opened.</p>
+
+<p>Miss Brown entered in great haste. She was pale and breathless, and
+Cole could see that something of a startling nature had happened. The
+seven men rose and bowed as she came up to the table.</p>
+
+<p>“What is it?” asked the spokesman.</p>
+
+<p>For a moment the girl’s eyes rested on Cole’s face. There was a
+mingling of questioning, suspicion, and reproach in them that
+bewildered him. Then she turned to the spokesman. “The red light is
+flashing on the indicator!” she breathlessly declared. “Some one is
+coming up the elevator!”</p>
+
+<p>For a moment each man in the room stood rigidly still. Then came a
+shuffling of feet and scraping of chairs. Now and then an ominous
+mutter was heard. Then, with one accord, all glances turned
+threateningly in the direction where Cole stood.</p>
+
+<hr class="chap x-ebookmaker-drop">
+<div class="chapter">
+<p><span class="pagenum" id="Page_106">106</span></p>
+<h2 id="chap_IX">CHAPTER IX</h2>
+<div class="subheadc">THE RED LIGHT</div>
+</div>
+
+<p class="drop-cap">FOR a time no one in the room moved. Cole was both amused and puzzled
+by the hostile glances leveled in his direction. The attitude of The
+Unknown Seven had changed from friendliness to suspicion, with an
+abruptness that was almost ludicrous. Miss Brown’s reference to a red
+light seemed to have turned them against him in a twinkling.</p>
+
+<p>He could not understand. He looked at the spokesman as if expecting an
+explanation. Now, with the lights on and the mask removed, Cole thought
+there was something familiar about his face. It was hewn on rather
+rough lines, suggestive of a man of great strength and determination.
+The iron-gray hair curled a little. The mouth was firm and gave a trace
+of harshness to the face. The eyes, arched by upslanting brows, were
+clear and cold.</p>
+
+<p>Just now those eyes were gazing fixedly at Cole. There was the faintest
+suspicion of a threat in them, he thought. He pondered for a moment,
+arranged a few scattered recollections, and then the man’s name came to
+him. He was Grover Carlin, a criminal lawyer of high standing and great
+ability. Cole had once heard him make a masterly address to a jury.</p>
+
+<p>Only a few moments had passed since Miss Brown had made her breathless
+announcement. <span class="pagenum" id="Page_107">107</span>Now one of the seven men sprang toward the door, and the
+others followed. Cole and Carlin, walking side by side, brought up the
+rear. The foremost of the procession opened a door across the hall, and
+the others tumbled in after him. It was a large room, filled with desks
+and filing cases, but the first thing that caught Cole’s eye was a
+globe of glass in which a red light was flashing at intervals of a few
+seconds.</p>
+
+<p>“What does it mean?” he asked Carlin.</p>
+
+<p>The lawyer gave him a sharp glance. “It means that a stranger is coming
+up the elevator,” he announced shortly.</p>
+
+<p>“Why a stranger? Couldn’t it be one of your own men?”</p>
+
+<p>“No. When our own men enter the private elevator they always throw a
+lever which prevents the light from flashing. The red light is a danger
+signal. The elevator is an automatic one, and it is impossible for a
+stranger to operate it unless he is acquainted with the mechanism. Our
+visitor must have got the hang of it, somehow. Mr. Cole, you are the
+only outsider who has been inside this establishment in weeks.”</p>
+
+<p>“Am I to infer that I am under suspicion?”</p>
+
+<p>“Well, it looks rather queer.”</p>
+
+<p>Smiling, Cole watched the flickering red in the glass globe. “But you
+admitted yourself that I am a twenty-four-carat man.”</p>
+
+<p>The other nodded. “Yes, I know, but——”</p>
+
+<p>“Perhaps you suspect I arranged to have myself followed here this
+evening?”</p>
+
+<p>“Such a thing is conceivable.”</p>
+
+<p><span class="pagenum" id="Page_108">108</span></p>
+
+<p>“But the rest isn’t very practicable. I never saw the elevator, much
+less learned how to operate it. I was blindfolded both times I came up
+in it.”</p>
+
+<p>“True, but you are a very clever man, Mr. Cole. Your performance of
+last night proved that. And the fact remains that you are the only
+stranger who has been inside this establishment in a long time.”</p>
+
+<p>The red flashes had ceased. Cole looked about him. Several of the men
+were glowering at him, while Miss Brown regarded him with a look of
+doubt and vague disappointment.</p>
+
+<p>“What about the former executive you mentioned, the man who betrayed
+you?” he asked. “Isn’t it possible that he is up to deviltry of some
+kind?”</p>
+
+<p>Carlin shook his head. “The mechanism has been changed since he left
+us. Besides, he would know enough to turn the lever to prevent the
+light from flashing. It will be interesting to see whether our visitor
+knows how to operate the sliding panel in the wall. If he does, you
+will presently see a green light in the indicator.”</p>
+
+<p>It was evident that the lawyer was trying to be fair and withhold
+judgment, but Cole could see he was an object of grave doubt. The
+others in the room were intently watching the indicator, but now and
+then they glanced darkly at Cole. Several of them seemed loath to
+suspect him, and among them was Miss Brown; but apparently they could
+think of no other explanation for the mysterious intrusion than that he
+had played false with them.</p>
+
+<p>Like the others he fell to watching the glass globe. The ceasing of
+the red flashes seemed to <span class="pagenum" id="Page_109">109</span>indicate that the intruder had reached the
+top floor. Perhaps at this very moment he was searching for the hidden
+spring that controlled the panel in the wall. Cole felt a tingling
+suspense as he waited to see whether a green light would appear in the
+indicator.</p>
+
+<p>“What can the fellow hope to gain by coming here?” he asked Carlin.</p>
+
+<p>The lawyer gave him a searching glance, as if not quite sure that the
+question had been asked sincerely. “A lot,” he said dryly. “There
+are papers in our files, evidence in the form of memoranda and legal
+documents, that certain parties would be willing to pay a great price
+for.”</p>
+
+<p>“But doesn’t he realize that you won’t give them up without a fight?”</p>
+
+<p>“Usually only the watchmen are here as late as this.” The lawyer gave
+Cole another dubious glance out of his cold eyes. “To-night and last
+night we have been holding special sessions on your account. Probably
+our unbidden visitor doesn’t know that. If he is hoping that he will
+have only a couple of watchmen to deal with, there will be a surprise
+waiting for him as soon as he gets through the wall, if he does get
+through.”</p>
+
+<p>Evidently the intruder was having difficulties. For several minutes the
+indicator had been blank, but the glances of those in the room were
+drawn to it as to a magnet.</p>
+
+<p>Cole’s eyes traveled over the oddly assorted company. A few feet in
+front of him stood a retired financier, a multimillionaire, who had
+once been a power in Wall Street, and whose money was being <span class="pagenum" id="Page_110">110</span>used
+unsparingly to fight corruption and vice. A little to one side was a
+philanthropist whose annual benefactions mounted into eight figures.
+Three or four of them were strangers to him, and among these was the
+surgeon, whose tall figure Cole easily recognized despite the fact that
+he had worn a disguise on the other occasions.</p>
+
+<p>His mind was active while he studied the faces about him. Would the
+green light flash on the indicator? Who was the intruder, and was
+Carlin right in the surmise that the documents in the filing cases
+were the object of the mysterious visit? For a thief to sneak into an
+establishment of this kind looked like a piece of foolhardy daring
+to Cole. There were nine of them in the room, including Miss Brown
+and himself, and no doubt agents and operatives of The Unknown Seven
+were within calling distance. There was a lively tussle ahead of the
+prowler, if he should succeed in getting through the wall.</p>
+
+<p>Ten minutes had passed since the red flashes stopped. Cole was
+beginning to think that the intruder had met insuperable obstacles.
+Perhaps he had in some manner learned how to operate the elevator, but
+had failed to familiarize himself with the mechanism that controlled
+the sliding panel in the wall. All the while, as these speculations ran
+through Cole’s mind, he felt that Carlin was watching him out of the
+tail of an eye.</p>
+
+<p>“Aren’t you a bit hasty in turning to me with your suspicions?” he
+asked good-naturedly. “I may be a twenty-four-carat man, but I am not a
+worker of miracles, and I’d have to be one in order to <span class="pagenum" id="Page_111">111</span>ferret out your
+secrets on such short acquaintance. What about your hired agents?”</p>
+
+<p>“I trust them as I trust myself. They have been tested and found true.”</p>
+
+<p>Cole smiled engagingly. “Your experience with the renegade executive,
+whom you told me about, should have warned you that tests aren’t always
+conclusive. Human nature is about as uncertain as April weather.”</p>
+
+<p>Carlin gave an assenting nod, but the argument did not seem to
+influence him greatly.</p>
+
+<p>“How will you dispose of the rascal if he gets through?” was Cole’s
+next question.</p>
+
+<p>“That’s a problem. Our success so far has been due largely to the
+secrecy with which we have surrounded ourselves. We have nothing to
+fear, and no great harm would be done if we should be found out, but we
+prefer to continue to work in the dark. So far our absconding executive
+seems to have kept his mouth closed, for nothing has leaked out about
+us. No doubt he is so busy spending his thirty pieces of silver that
+he has no time for gabbling. Besides, the scoundrel has a wholesome
+respect for us. He knows that The Unknown Seven has a long arm and a
+sturdy fist. If this fellow,” with another glance at the indicator,
+“should get through the wall, we shall have to take measures to protect
+our privacy. If we find that he has the right stuff in him we may even
+invite him to join us.”</p>
+
+<p>Another five minutes passed. Some in the group showed signs of
+restiveness. One of them suggested <span class="pagenum" id="Page_112">112</span>going out and collaring the
+prowler, but Carlin vetoed the idea, declaring it would be better to
+give the fellow a chance to show his hand.</p>
+
+<p>The group resumed its silent waiting. A question occurred to Cole, one
+that he had been on the point of asking when Miss Brown’s entrance
+interrupted the conversation in the other room.</p>
+
+<p>“How is Mr. Reeves?” he inquired.</p>
+
+<p>Carlin waited for several moments before he answered. “There has been
+no change in his condition in the past twenty-four hours,” he finally
+announced.</p>
+
+<p>“He is still here?”</p>
+
+<p>The lawyer nodded. He did not seem very communicative on that subject.</p>
+
+<p>“You know, of course,” Cole went on, “that it isn’t in strict
+accordance with the law for you to keep him here?”</p>
+
+<p>A thin smile twisted Carlin’s lips, but his only response was a shrug.</p>
+
+<p>“My duty to my clients gives me an interest in the matter,” Cole
+pointed out. “You are keeping Mr. Reeves a prisoner.”</p>
+
+<p>“By no means. Mr. Reeves is our guest, and so far he has not voiced
+any objections.” He gave a grim chuckle. “Furthermore he is infinitely
+better off here than where we found him. He would probably have been
+dead by this time if we hadn’t taken him away.”</p>
+
+<p>“From where?”</p>
+
+<p>The lawyer’s wintry gaze rested for an instant on his face. “From the
+residence of Professor <span class="pagenum" id="Page_113">113</span>Carmody, as you probably either know or can
+readily guess.”</p>
+
+<p>“You kidnaped him?”</p>
+
+<p>“Call it that if you like. We saved Mr. Reeves from certain death.
+Professor Carmody is the only one who has cause for feeling aggrieved
+at what we have done.”</p>
+
+<p>Cole nodded thoughtfully. He had kept Carmody under observation for
+some time, and of late he had noticed a change in him. He understood
+now why the professor had seemed excited and ill at ease the last few
+days. His comings and goings had been more frequent and there had been
+several signs of something unusual on foot about the house on Bleecker
+Street.</p>
+
+<p>“So that you may feel quite reassured in the matter,” Carlin went on,
+“let me tell you that Mr. Reeves is under excellent care. A specialist
+is studying his condition, and there’s a chance, though a very remote
+one, that he may recover his mental faculties, wholly or in part. If he
+does, I fancy he will have a very entertaining story to tell.”</p>
+
+<p>He looked sharply at Cole just then, as if trying to measure the effect
+of his words, but Cole’s face showed nothing but deep thought. He had
+obtained a glimpse into the working methods of The Unknown Seven, and
+he had found fresh proof of the efficiency and the resources of the
+organization. A splitter of hairs might not have found its methods
+strictly legal, but there was such a thing as the end justifying
+the means. Quite likely Carlin was right in saying that Reeves had
+been rescued from certain death at the hands of Professor <span class="pagenum" id="Page_114">114</span>Carmody.
+Probably, too, a great deal more could be accomplished by this informal
+course of procedure than by strict adherence to the letter of the law.
+Cole was so deeply impressed that for the moment he forgot that he was
+under suspicion.</p>
+
+<p>“If Reeves ever tells his story, I’d like to be there,” he declared.</p>
+
+<p>“You may have an opportunity to do so,” dryly remarked the lawyer.
+“Until we have satisfied ourselves on one or two little points we shall
+have to ask you to remain here as our guest. In the meantime——”</p>
+
+<p>A medley of mutters and hushed exclamations interrupted him.
+Instinctively Cole glanced at the indicator. A tongue of green flame
+was shooting up and down in the glass globe. Fascinated, he watched the
+darting flashes.</p>
+
+<p>“Get back!” ordered Carlin, waving a hand at the men who stood huddled
+into a knot before the indicator. In his other hand gleamed the barrel
+of a pistol. Cole admired the ease and coolness with which he was
+taking charge of the situation. Following the direction of his pointing
+finger, the men crowded into a corner of the room. Miss Brown followed
+them, and, as she crossed the floor, she gave Cole a glance that
+stabbed within him.</p>
+
+<p>Carlin touched a button; the room went dark. Keeping Cole close at his
+side he took up a position a few feet in front of the others. “I must
+warn you not to move,” he whispered in Cole’s ear.</p>
+
+<p>“Have no fear,” Cole whispered back. “I’m as anxious to see this
+through as you can possibly be.”</p>
+
+<p>The lawyer’s strategy was simple. If the intruder’s <span class="pagenum" id="Page_115">115</span>aim was to get
+hold of some of the documents in the filing cases he would probably
+come straight to this room. The fact that he had mastered the mechanism
+of the elevator and the hidden door seemed to indicate that he was
+fairly well familiar with the lay of the establishment. Evidently the
+lawyer’s plan was to catch him red-handed and take him by surprise.</p>
+
+<p>Cole was conscious of a growing disquietude as he stood beside the
+lawyer, looking in the direction of the door through which the intruder
+must pass. He had a hazy feeling that Carlin’s plan was too simple, but
+he could not tell exactly what was wrong with it. Not a sound was heard
+in the room. The door had been left open a crack, and a narrow wedge of
+light filtered in, but most of the room was an impenetrable blur.</p>
+
+<p>A minute passed. In vain Cole strained his ears to catch the sound of
+approaching footsteps. His uneasiness grew, but he could not understand
+why. As if his misgivings had been communicated to the lawyer, the
+latter mumbled something under his breath. The moments flew, and still
+no sound was heard in the corridor. Either the intruder’s footfalls
+were thoroughly muffled, or else——</p>
+
+<p>Cole did not finish the thought. A vagrant suspicion held his senses
+spellbound. For a moment longer he listened for footfalls that did not
+come, and then his vague apprehensions crystallized in a flash. He
+gripped the lawyer’s arm so violently that Carlin gasped.</p>
+
+<p>“You were wrong!” he whispered hoarsely. “The <span class="pagenum" id="Page_116">116</span>fellow isn’t after any
+papers. He came here to get Reeves.”</p>
+
+<p>Cole, with his hand tightly gripping Carlin’s arm, felt a sudden shock
+shooting through the man at his side. In a twinkling the lawyer seemed
+to have grasped his meaning. Now, muttering something, he sprang
+forward. In an instant the lights were on again, and Carlin was running
+toward the door. Cole followed, but in a moment the two men came to a
+dead stop.</p>
+
+<p>A short, piercing cry sounded. It died abruptly, leaving a curious
+emptiness in the air. The two men stared at each other, and Cole saw a
+gray film creep over the lawyer’s face.</p>
+
+<p>“Too late!” he exclaimed.</p>
+

+<div class="subheadc">PURSUIT</div>
+</div>
+
+<p class="drop-cap">THE scream had ended with a certain grim abruptness that to the
+listeners could mean only one thing. It had seemed to stop in the
+middle; yet it had been punctuated with an ominous finality. It was as
+if death itself had stepped in and placed an exclamation point after an
+unfinished cry.</p>
+
+<p>Then came utter silence. It seemed as though every sound and every
+breath of life had been sucked out of the air. Carlin, his lips drawn
+apart at one side, looked fixedly at the door. His head, shoulders and
+chest were straining forward; he appeared to be maintaining his balance
+by sheer mental tension. A few moments passed, and then Cole shook
+himself free of the insidious horror that attacks even the strongest.
+Less than thirty seconds had elapsed since the cry sounded.</p>
+
+<p>“Where is he?” he asked, shaking the lawyer’s arm.</p>
+
+<p>“He?” Carlin seemed to be trying to shake off a spell. “Oh, Reeves, you
+mean. Back there.” He pointed indefinitely toward the corridor.</p>
+
+<p>“Brace up, man!” Cole shouted. “Go to him. Maybe something can be done.
+Hurry!”</p>
+
+<p>He bounded to the door and out in the hall. His words had voiced a hope
+that he did not feel. The cry had told him only too eloquently that
+Reeves was beyond help. But there might still be time to <span class="pagenum" id="Page_118">118</span>catch the
+murderer, if he made haste. Heedless of Carlin’s belated shout to him
+to stop, he hurried down the long and dimly-lighted corridor. Confused
+cries and scurrying footfalls sounded behind him, signifying that the
+others had come out of their temporary stupor.</p>
+
+<p>Cole shut his ears to the bedlam. All he saw and heard was a shadow
+darting toward the end of the hall and a patter of swift feet. At the
+farther end of the corridor, at the point where Miss Brown and himself
+had entered the headquarters of The Unknown Seven, was an opening. He
+came up to it just in time to see the fleeing shadow slip through.</p>
+
+<p>“Stop, or I’ll wing you!” he cried, jerking his pistol out of his hip
+pocket, but the fugitive paid no heed. Crouching low, he ran with
+zigzagging motions across the open space toward the elevator shaft.
+Cole aimed low and pulled the trigger. The bullet thudded against the
+flagged flooring, and through the smoke he saw the fugitive spring into
+the cage. Already the door was clanking shut. He plunged forward and
+kicked his foot into the opening, just in time to stop the sliding door
+from closing. He caught a glimpse of a stiff felt hat, a sallow face
+with a mocking grin, a lean and slightly hunchbacked figure, and then
+the cage shot downward.</p>
+
+<p>Cole, standing with his right foot caught between the door and the
+steel jamb, muttered a malediction, but it was aimed mostly at himself.
+The little hunchback had eluded him with an agility that aroused his
+admiration, even while it made him <span class="pagenum" id="Page_119">119</span>grit his teeth. He flung the
+door wide open. Only a few moments had passed since the cage started
+downward, and it had not got far. There was something tantalizing about
+the swiftness with which it increased the distance between himself and
+the fleeing man.</p>
+
+<p>For a moment Cole gauged his chances. He gazed at two sets of cables
+that glided up and down inside the shaft. His next move would have
+seemed foolhardy to an onlooker, but Cole had carefully measured the
+risk. It was one of those tense moments in which the mind leaps quickly
+to decisions. The time it took him to determine what to do was only a
+matter of seconds.</p>
+
+<p>He flexed his muscles and then he leaped. For an instant his form
+hurtled through space, then his hands closed tightly around the
+downward gliding cable. He wound his legs about it and clamped it
+between his feet. The swift descent made him feel as if he were sucking
+ice-cold air into his lungs. The cage, some twenty-five or thirty feet
+below, was dropping like a rock, but now Cole was following at an equal
+rate of progress.</p>
+
+<p>Ten floors slipped past, then fifteen, finally twenty. Cole’s hands
+were raw and bleeding. Hot and cold flashes were chasing up and down
+his back. His lungs were straining, and a treacherous numbness was
+creeping into his limbs. He looked down at the roof of the cage and
+smiled. No doubt the fleeing man felt that his escape was already as
+good as accomplished.</p>
+
+<p>The cage stopped so suddenly that the vibration of the cable almost
+made Cole lose his hold. He <span class="pagenum" id="Page_120">120</span>slipped a little farther down, then
+checked his descent opposite the level of the second floor. The shaft
+was narrow, and he could easily reach the door with one hand, while he
+clung to the cable with the other. Installed for private and secret
+use the elevator equipment lacked several safety devices that would
+have acted as a hindrance to Cole. As it was the door slid open easily.
+Seizing the jamb with one hand he swung free of the cable and landed on
+the floor.</p>
+
+<p>He felt a trifle dizzy, but the thrill of pursuit acted as a stimulant.
+Just around the shaft was a stairway, and he hurried down. Only a few
+moments ago a metallic clanking had signified that the fugitive was
+getting out of the cage. As Cole reached the lower steps he saw a long
+open space in front of him, and at its farther end he caught a glimpse
+of the hunchback, slipping out through the door. His ears caught
+the sound of throbbing motors, warning him that a car was waiting
+outside to speed the fugitive to safety. Conscious of nothing but the
+exhilaration of the hunter he bounded to the door and emerged on the
+sidewalk, just as a tail light gave him a mocking wink and disappeared
+around the corner.</p>
+
+<p>There was a fine mist in the air. On all sides the tops of the tall
+office buildings reared their heads in a translucent haze. The streets,
+which in the daytime swarmed with humanity, were now deserted. Cole
+guessed that it must be about two o’clock, but he did not take time to
+look at his watch. The taunt of the tail light egged him on. He threw
+his head back and his chest out <span class="pagenum" id="Page_121">121</span>and broke into a sprint. Rounding the
+corner at full speed he once more caught a glimpse of the jeering tail
+light. But it was only a glimpse, for a moment later it was out of
+sight.</p>
+
+<p>Cole tried to run faster, but he realized that, unless something
+unforeseen happened, he was running a losing race. The car had the
+advantage in speed and endurance. With scarcely a stop, save for the
+possible interference of a traffic officer, it might travel all the way
+from one end of Manhattan to the other. He kept up the pursuit only
+because he hated to cry quits. Besides, as long as he could continue
+the chase, there was always the possibility that chance might come to
+his aid.</p>
+
+<p>Once more he caught sight of the tail light, this time quite a distance
+ahead. Letting out the final ounce of energy he succeeded in quickening
+his speed a little. He ran and ran, but his breathing became alarmingly
+heavy. It would not be long before his wind gave out, but at least he
+would have the satisfaction of knowing that he had done his best. His
+gait was growing wabbly when the unexpected occurrence for which he had
+been hoping came along.</p>
+
+<p>Not even a village street is quite so dead as is the financial section
+of New York in the small hours. Skyscrapers, towering in a jungle of
+silence and dim lights, give a majestic touch to a stillness that is
+seldom broken, save by the footfalls of policemen and private watchmen.
+To Cole, therefore, it seemed nothing but a stroke of luck that a
+taxicab should come along at that moment. He hailed the driver.</p>
+
+<p><span class="pagenum" id="Page_122">122</span></p>
+
+<p>“See that car?” He pointed at the tail light twinkling in the distance.
+“Can you overtake it?”</p>
+
+<p>“I’ll try,” said the chauffeur, peering at him from beneath the visor
+of his cap. “This is a pretty good old boat, though she ain’t much on
+looks. Good for a fine if I get pinched?”</p>
+
+<p>“Sure,” said Cole easily, though not altogether unmindful of the
+slender roll in his pocket. He stepped in, and the cab jumped forward.
+It rattled and lurched and creaked in the joints, as if in imminent
+danger of falling to pieces, but he noticed with satisfaction that it
+had a surprising capacity for speed. It swerved and slithered at a
+giddy rate, at times almost jogging him out of his seat.</p>
+
+<p>Pursued and pursuer wound their way out of the maze of chopped-up and
+tangled streets to the south of Washington Square. The car ahead swung
+into Fifth Avenue, at a slightly reduced speed, and the taxicab slowed
+down accordingly. From now on it was not only easier to keep up with
+the larger car, but there was also less danger of the fugitive becoming
+aware of pursuit, for, even at that hour, there was a sprinkling of
+traffic on the avenue.</p>
+
+<p>It suddenly dawned on Cole that he was in a unique position. The
+capture of the hunchback now seemed certain, but what was he to do with
+the man after he had caught him? If he turned him over to the police,
+which seemed the proper and regular thing to do, he would be compelled
+to tell things which, in a sense, he was pledged not to reveal. Despite
+all that had happened and notwithstanding the harsh treatment inflicted
+on him, he had come away with a rather high opinion of The Unknown
+<span class="pagenum" id="Page_123">123</span>Seven. They had trusted him, at least for a time, until the coming of
+the hunchback turned their suspicions against him, and Cole was not
+inclined to violate a trust.</p>
+
+<p>Now, that he came to think of it, there was really very little he could
+tell, even if he were disposed to divulge what he knew. In a strict
+sense he did not know that the hunchback had murdered Reeves. For
+that matter he did not know that Reeves was dead. Though personally
+convinced on both points he could not tell a convincing story to the
+police, for he had neither witnessed the commission of the crime nor
+seen Reeves’ dead body.</p>
+
+<p>Still another thought came to him as he bobbed up and down and from
+side to side in the cab. He gave a short, dazed laugh. Even if he had
+witnessed the deed and seen the body he would have been unable to
+direct the police to the scene of the crime. His dizzying descent in
+the elevator shaft had left him a trifle giddy. He had rushed away in
+great haste, his whole mind fixed on the one idea that the hunchback
+must not be permitted to get away. In his hurry he had given no thought
+to the location of the building. He had strained every nerve and muscle
+in his efforts to keep the car in sight, and there had been no time to
+notice street signs. Like many a New Yorker, he had seldom had occasion
+to visit the financial section, and many of the streets in that
+district were nothing but names to him.</p>
+
+<p>Though there was ample extenuation, Cole chided himself for a
+blunderer. He had missed <span class="pagenum" id="Page_124">124</span>his chance to learn where the headquarters
+of The Unknown Seven was situated. The general boundaries of the
+neighborhood were a shade more clearly defined in his mind, but he
+knew scarcely more than he had known before. The rendezvous of the
+organization could be in any one of half a hundred buildings. Even
+if he should stumble upon the right one he doubted whether he would
+recognize it.</p>
+
+<p>In the midst of his musings the cab stopped with a suddenness that
+jerked him out of his seat. He glanced out and saw that the hunchback’s
+car had halted two blocks ahead. They were somewhere in the Sixties,
+and to the west were the black masses of the park. The hunchback was
+getting out and turning down the side street, but car and driver were
+proceeding north.</p>
+
+<p>A suspicion was dawning in Cole’s mind as he stepped out of the
+taxicab. It was rather odd that the chase should have ended at this
+particular point. He paid the chauffeur, adding a generous tip to the
+fare. He hurried to the corner where the car had stopped and swung into
+the side street, just in time to see the hunchback disappear in the
+shadow of a house. Cole hastened after him, stopping before a dark and
+somber house with a brownstone front.</p>
+
+<p>His hazy suspicion was confirmed. It was odd how the scattered pieces
+of the mystery were beginning to dovetail. His pursuit of the hunchback
+had led him to the house of Doctor Dickson Latham.</p>
+

+<div class="subheadc">BEHIND THE LOCKED DOOR</div>
+</div>
+
+<p class="drop-cap">THE moon was shining through a silver-gray mist, giving the row of
+buildings a shadowy appearance. A fresh fragrance drifted out from the
+park, on the scarcely perceptible breeze. A milk cart rattled down the
+block; otherwise the street was deserted.</p>
+
+<p>Cole peered sharply into the dark basement entrance. He suspected the
+hunchback had entered the doctor’s house that way. Down the steps he
+went and tried the knob, but the door was locked. The two windows on
+each side were protected by iron bars. He hesitated for a moment, and
+then he mounted the steps to the main entrance and rang the bell. There
+seemed to be nothing else he could do, and the shifty-tongued doctor
+interested him strangely. Latham’s evasions would be entertaining, if
+nothing else.</p>
+
+<p>He waited patiently, for he had many things to consider. Just what
+trend the forthcoming interview was to take he did not know. That
+the hunchback should have taken refuge in the physician’s house was
+significant, especially since there were good reasons for supposing
+that Latham was responsible for the wrecking of Reeves’ mind. That he
+had also instigated the murder of the maniac seemed only a reasonable
+sequence of the first supposition. In this connection Professor
+Carmody’s <span class="pagenum" id="Page_126">126</span>visit to the doctor’s house yesterday was a highly
+interesting circumstance. Perhaps the two rogues had planned the murder
+then.</p>
+
+<p>Cole rang again. At the same time he brushed all hasty inferences and
+surmises from his mind. He came back to the point that, as far as hard
+facts were concerned, he knew next to nothing. He did not even have a
+good reason for placing the hunchback under arrest. If he turned the
+fellow over to the police he would probably be only laughed at for his
+trouble. The hunchback would brazen out of it, and Cole would not have
+a leg to stand on. As for Doctor Latham——</p>
+
+<p>He rang again more emphatically this time. Then he listened to the
+queer noises which the reverberations stirred up within the dark house.
+As for Doctor Latham, Cole could hope to do no more than draw the
+doctor out by deftly aimed questions. It was scarcely to be expected
+that such a slippery individual as Dickson Latham would betray himself,
+yet something might come of the interview. The doctor might get
+careless, or Cole might succeed in confusing him.</p>
+
+<p>Once more he reached for the button, but just then a step sounded in
+the hall. The door came open. It was the doctor himself who admitted
+his early caller. It was dark where they stood, and Cole could see
+little else than a black beard and a long dressing gown, but he fancied
+there were signs of repressed irritation about the doctor, as he
+recognized his visitor.</p>
+
+<p>“Ah, it’s you, Mr. Stone. Please step in.”</p>
+
+<p>The voice was affable enough. Cole followed <span class="pagenum" id="Page_127">127</span>him through the hall, the
+reception room, and into the physician’s office. When they faced each
+other across the desk, Latham seemed to have recovered his usual ease
+of manners. “Nerves again, Mr. Stone?” he asked pleasantly.</p>
+
+<p>“No; only a slight headache,” said Cole.</p>
+
+<p>“And you wish me to prescribe something?”</p>
+
+<p>“Yes, but it isn’t drugs I want. I came here hoping you would
+cure my headache by removing the cause. I have an acute case of
+flabbergastation.”</p>
+
+<p>Doctor Latham’s bearded lips parted in a thin flash of very white
+teeth. Cole thought there was something Machiavellian about the smile.
+The physician reached out an arm and passed a box of cigars across the
+desk. A startled gleam flashed into Cole’s eyes. The movement of the
+doctor’s arm had wrinkled the sleeve of the dressing gown and exposed
+a narrow rim of the cuff of his pajama jacket. The cuff was pale blue,
+and just above the rim was a stain.</p>
+
+<p>“I can recommend these perfectos,” said Latham genially.</p>
+
+<p>Cole, easily hiding his surprise, accepted one. The doctor struck a
+match, and the stain became visible once more, as he helped Cole to a
+light. It was a fresh blot of a dark tinge, probably not more than an
+hour old.</p>
+
+<p>“What is it that flabbergasts you, Mr. Stone?” inquired the physician,
+after each man had pulled appreciatively at his cigar. The question was
+accompanied with a slight and seemingly casual glance at a door in the
+rear of the office.</p>
+
+<p><span class="pagenum" id="Page_128">128</span></p>
+
+<p>The glance had not escaped Cole. He picked his words carefully.
+“Fifteen or twenty minutes ago,” he began, “a man entered your house.”</p>
+
+<p>“Yes?” asked the physician in a toneless voice.</p>
+
+<p>“A hunchback,” Cole went on, guessing that the doctor had carefully
+hidden the fellow, while Cole had been kept waiting outside the door.
+“He entered your basement, unless I’m mistaken. Odd time for a call,
+doctor.”</p>
+
+<p>“A physician, as you undoubtedly know, receives callers at all hours.
+Nothing unusual in that.”</p>
+
+<p>“But you will admit that this fellow’s mode of entrance was rather
+irregular? A physician’s patients do not usually sneak in the basement
+way.”</p>
+
+<p>“Very true, but please come to the point, Mr. Stone. You must grant
+that I have a right to receive visitors any way I choose, even through
+the chimney, if it pleases my fancy. You tell me that a hunchback
+entered my house by the basement door. I neither deny nor affirm it,
+but, without wishing to seem rude, may I ask what it is to you?”</p>
+
+<p>“Suppose the fellow were a criminal?”</p>
+
+<p>“I never inquire into the moral character of my patients. Their
+physical welfare is all that concerns me.”</p>
+
+<p>“But suppose this individual had committed a murder? You would not care
+to harbor a murderer in your house, would you?”</p>
+
+<p>A slight flicker of uneasiness showed in the doctor’s eyes. “A
+murderer? Aren’t you carrying your suppositions rather too far, Mr.
+Stone?”</p>
+
+<p>Again he cast a sidelong glance at the inner door. Cole sensed a hidden
+significance in the doctor’s attention <span class="pagenum" id="Page_129">129</span>to that door. It puzzled him
+almost as much as did the stain on the cuff. He thought quickly,
+estimating how much he stood to gain or lose by a direct attack.</p>
+
+<p>“I’m not supposing,” he declared bluntly. “I know there is a murderer
+in your house.”</p>
+
+<p>“Oh!” The doctor’s tone was tense and very low. “Whom did he murder?”</p>
+
+<p>“Malcolm Reeves.”</p>
+
+<p>“Mal—Malcolm Reeves?” In an instant the physician had kicked back his
+chair and was on his feet. With the cigar tightly clamped between his
+bearded lips he stared hard at Cole. His eyes were bright as metal, but
+there was a glint of grave concern in their depths. In that moment Cole
+would have been ready to swear that Latham’s consternation was genuine.</p>
+
+<p>“Is Reeves dead?” asked the doctor hoarsely.</p>
+
+<p>Cole gave him a level glance. “He was murdered less than two hours ago,
+and the murderer is in your house.”</p>
+
+<p>The physician stared for a moment longer. An indistinct mutter came
+from his lips. Cole wondered whether his face was not pale under the
+glossy black beard. Despite his bewilderment and his feeling that the
+doctor’s emotions were sincere, he glowed inwardly with satisfaction.
+At last Latham’s superb composure had been shattered; now he must
+pursue his advantage before the doctor could rally his mental forces
+and ply him with unanswerable questions.</p>
+
+<p>“Doctor Latham,” he asked quickly, “do you <span class="pagenum" id="Page_130">130</span>deny that there is a
+hunchbacked fellow in the house?”</p>
+
+<p>The doctor sat down again. “I don’t feel called upon either to deny or
+affirm it,” he declared.</p>
+
+<p>Cole leaned forward across the desk. “How did that stain get on your
+cuff, doctor?”</p>
+
+<p>The physician’s arm was stretched out flat on the table, and Cole
+pointed to the soiled cuff. Latham looked down; for an instant, as he
+saw the blot, his eyes widened in astonishment.</p>
+
+<p>“Oh, that!” He shrugged his shoulders. “I had a simple surgical case
+a while ago. It wasn’t serious enough to take to a hospital, so I
+performed it in my own office.”</p>
+
+<p>“I didn’t know physicians ever performed operations in their pajamas.
+No accounting for eccentricities, though. Will you do me a favor,
+doctor?”</p>
+
+<p>“That depends. What is it?”</p>
+
+<p>Cole pointed carelessly to the door at which the doctor had been
+covertly glancing from time to time.</p>
+
+<p>“I would like to see what is behind that door, if you don’t mind,” he
+remarked languidly.</p>
+
+<p>Again a gleam of uneasiness crept into the doctor’s eyes. He regarded
+Cole intently, as if trying to ferret out the reason for the request.
+Cole, a thin smile on his lips, was puffing leisurely at his cigar.</p>
+
+<p>“Why?” demanded the doctor.</p>
+
+<p>“Just a fancy. You have no objection, I hope?”</p>
+
+<p>The doctor drew himself up. He sat stiffly erect in his chair. A mask
+seemed to fall from his face. Dropping all pretense of geniality, his
+features took on a threatening look. “I don’t care to humor your fancy,
+Mr. Stone,” he declared coldly.</p>
+
+<p><span class="pagenum" id="Page_131">131</span></p>
+
+<p>With excessive care Cole ashed his cigar. Then he got up and, with a
+slow, but firm, tread, walked toward the door in the rear. His fingers
+closed around the knob.</p>
+
+<p>“Stop!” cried the doctor sharply.</p>
+
+<p>Cole turned and gave him an amused glance.</p>
+
+<p>“You are a detective, I suppose?” said Latham.</p>
+
+<p>“In a way,” admitted Cole modestly.</p>
+
+<p>“Have you a search warrant?”</p>
+
+<p>Cole shook his head.</p>
+
+<p>“Then I must regard you as a trespasser. Mr. Stone, the moment you open
+that door you will be a dead man.”</p>
+
+<p>He reached into a pocket of his dressing gown. In the next instant a
+small pistol glittered banefully in his hand. He raised it till Cole
+could gaze straight into the muzzle. His eyes, as he looked ominously
+at him, emitted the same cold, metallic gleam as the barrel of the
+weapon.</p>
+
+<p>Cole gave him a long, searching look, and he was a keen judge of faces.
+At the end of the inspection he shrugged. “Doctor Latham,” he said
+evenly, “you haven’t the nerve to kill me.” He turned the knob and
+walked in.</p>

+<div class="subheadc">IN FOUR ROUNDS</div>
+</div>
+
+<p class="drop-cap">IN stony silence Doctor Latham watched the bold move. As Cole opened
+the door, a diffident look came into his face. He toyed awkwardly with
+the pistol, looked dubiously at the barrel, finally put the weapon back
+in his pocket. “It seems you win this round,” he muttered.</p>
+
+<p>The room which Cole had entered was dark. His hand fumbled along the
+wall till he found a knob. At his pressure a light appeared, and it
+revealed a man sprawled out in a chair. Except that the coat had been
+removed he was fully dressed, and it seemed to Cole that he was sound
+asleep.</p>
+
+<p>He recognized the sallow face of the hunchback, having caught a brief
+glimpse of it just as the elevator started. It was not a pleasant face.
+The twisted lips looked as though the teeth had been bared in a snarl
+just before the man fell asleep. Cole thought he might be a thug or
+professional gunman. He looked away and saw Latham in the doorway.</p>
+
+<p>“You’re a cool one,” murmured the physician, a trace of admiration in
+his tone. “Didn’t you know I was ready to shoot you?”</p>
+
+<p>“You didn’t,” was the laconic answer.</p>
+
+<p>Latham came closer. He was once more suave and genial. Cole fancied
+his astute brain was at work on a scheme of some sort. “Have you seen
+<span class="pagenum" id="Page_133">133</span>enough to repay you for the risk you took?” he inquired. “Is this the
+man you are looking for?”</p>
+
+<p>Cole nodded. “He’s the one who murdered Reeves. Tough-looking customer!
+What have you done to him, doctor?”</p>
+
+<p>The Machiavellian smile came back. “He was in a bad way. I had to give
+him a hypodermic. That’s why his crime, if he committed one, doesn’t
+seem to weigh very heavily on his conscience. What are your intentions
+in regard to my patient, Mr. Stone?”</p>
+
+<p>Cole stepped closer to the recumbent man. The fellow looked indeed as
+though he were deep in drug-induced sleep. Cole raised the arm nearest
+him and turned back the shirt sleeve. A little below the elbow there
+was a small puncture. He dropped the limp arm and turned away. His
+head was full of perplexities and contradictions. A little while ago
+certain phases of the mystery had seemed to dovetail to perfection, but
+now things were taking an incongruous turn. He felt the physician was
+inwardly laughing at his bewilderment.</p>
+
+<p>“Well, Mr. Stone?” he inquired softly.</p>
+
+<p>Cole was in a quandary, but he tried hard not to show it. For the
+present the wily doctor had several strategical advantages, and
+evidently he knew how to use them. It would not be easy to take the
+unconscious man away. Even if it could be done, Cole would not know
+where to take him. On the other hand, it would not do to let him get
+away, as he undoubtedly would as soon as he recovered from the effects
+of the drug.</p>
+
+<p>“This man is my patient,” continued the doctor, <span class="pagenum" id="Page_134">134</span>“and I strongly advise
+against disturbing him for the present. I believe a physician’s advice
+is usually heeded in such cases.”</p>
+
+<p>“Your patient seemed to be in excellent health a little while ago,”
+observed Cole.</p>
+
+<p>“Really, you must permit me to be the judge as to his physical
+condition.”</p>
+
+<p>Cole eyed him levelly. “You are a very clever man, Doctor Latham. I
+believe you deliberately drugged this so-called patient of yours so
+that he couldn’t be removed. It was a fairly ingenious stroke.”</p>
+
+<p>Latham gave him a curious glance. “That’s a very odd way of looking at
+the situation,” he remarked thoughtfully. “I wonder if you aren’t a bit
+disingenuous. However, it doesn’t matter. This seems to be my round.”</p>
+
+<p>His faintly gloating tone nettled Cole. As far as he could see he was
+outmaneuvered on every point. Hopeless as the situation seemed to be,
+he was determined not to leave the house a defeated man. He rekindled
+his cigar, then gazed with mild reproach at the glowing tip. A cigar
+never gave him the mental stimulus that he derived from his musty
+old pipe at home. Besides, the doctor’s slyly amused glances were
+disconcerting. Cole’s thoughts would not travel in a straight line,
+and he grew more uncomfortable as he noticed that his helplessness was
+beginning to impress the doctor as queer.</p>
+
+<p>He turned, placed the half-smoked cigar on a tray, and glanced through
+the open door leading into the office. The nickel trimmings of a
+telephone gleamed under the electric drop light over <span class="pagenum" id="Page_135">135</span>the desk. The
+sight of the instrument seemed to give Cole an idea. Deliberately he
+walked into the other room and picked up the directory.</p>
+
+<p>“May I ask what you intend doing?” inquired the physician, following
+him.</p>
+
+<p>“I know a doctor who lives not far from here,” said Cole absently,
+while he hastily turned the pages of the book. “I’m going to call him
+in for a consultation over your patient. If the fellow is in a bad way,
+two doctors are better than one. If there’s nothing wrong with him, I
+want to know it. Ah!” his index finger halted in the center of a page.
+“Plaza 28826.”</p>
+
+<p>A faint mutter of dismay escaped the doctor. He stood at Cole’s back,
+while the detective put the receiver to his ear.</p>
+
+<p>“A consultation is quite unnecessary, I assure you,” declared Latham.</p>
+
+<p>Cole grinned into the transmitter. He suspected Latham would agree to
+bring his “patient” back to consciousness rather than have another
+physician called in. A thousand slight murmurs sounded on the wire, and
+then came the operator’s brisk “Number, please.”</p>
+
+<p>Cole spoke the number distinctly. He expected Latham would yield rather
+than suffer a blow to his professional reputation, but the physician’s
+cunning rendered the matter uncertain. And, even if his ruse succeeded,
+Cole would score only a temporary advantage. He was not yet sure what
+his next move was to be. While waiting for the connection he glanced
+over his shoulder. Latham, <span class="pagenum" id="Page_136">136</span>hands clasped at his back, was walking back
+and forth.</p>
+
+<p>Suddenly Cole’s face went blank. A jarring noise sounded in his ears.
+In the next instant he knew he was holding a dead instrument in his
+hand. All sounds had abruptly ceased. He heard Latham’s triumphant
+chuckle as he hung up the receiver.</p>
+
+<p>“It appears the third round is also mine,” murmured Latham, his bearded
+lips parting in a gratified smile. In his right hand he held a pair of
+steel nippers.</p>
+
+<p>Cole gritted his teeth, but smiled complacently. “I would call it a
+draw,” he said. “Your act of cutting the wire was a confession, doctor;
+a confession that you are up to deviltry. I knew it all along, of
+course, but I’m glad you showed your hand so plainly. It’s an advantage
+to me to know that you have something to fear.”</p>
+
+<p>“I hope you derive a lot of satisfaction from it,” declared Latham
+easily. “I fail to see how it is going to do you any practical good,
+though.”</p>
+
+<p>Cole himself was not quite clear on that point. It was a moral
+advantage rather than a physical one. He gazed steadily at the
+physician, studying the triangular outlines of the black, neatly
+trimmed beard. It was a bit tantalizing to consider how many shifting
+expressions that glossy appendage might conceal. It acted as a mask,
+and he was permitted to see through it only when the bearded lips
+parted in a flash of teeth. Just now the face told him nothing. It
+merely gave him an impression of a man of unfathomable secrets and a
+deeply <span class="pagenum" id="Page_137">137</span>plotting mind. Cole felt at once baffled and fascinated.</p>
+
+<p>“I am curious to know what you will try next,” said Latham after a long
+pause. “I don’t want to seem inhospitable, but I’m getting deucedly
+sleepy.” He yawned ostentatiously. “If you have nothing further to
+propose——” He looked significantly at the door.</p>
+
+<p>Cole considered for a moment longer, then he selected the most
+comfortable chair in the room and sat down. With a languid air he
+stretched out his legs and leaned back. “I am worried about your
+patient,” he declared, with a sly wink at the room in the rear. “If you
+have no objection, I’ll hang around till he comes to. This is a very
+comfortable chair. Could I trouble you for another of those excellent
+cigars?”</p>
+
+<p>The doctor stood in front of him, and Cole fancied there was a frown
+beneath the beard. “You are going too far,” said Latham severely.
+“Suppose I should throw you out?”</p>
+
+<p>“That would be very rude, doctor. Besides, it couldn’t be done.”</p>
+
+<p>Latham came a step closer. Slowly his crafty eyes moved up and down
+Cole’s figure. Evidently he concluded that the languid appearance of
+the man in the chair was deceptive.</p>
+
+<p>“I might summon help,” he suggested.</p>
+
+<p>“You might, but I hardly think you will. Being a prudent man, you
+realize it wouldn’t do to stir up things. It’s far preferable, from
+your point of view, to confine this interview to ourselves. What about
+another of those cigars, doctor?”</p>
+
+<p><span class="pagenum" id="Page_138">138</span></p>
+
+<p>Latham did not move. His eyelids narrowed a trifle as he continued to
+gaze at Cole. “You puzzle me,” he declared. “You come here representing
+yourself to be a detective, but your conduct is very peculiar. You say
+the hunchback in the other room is a murderer, but you have made no
+move toward arresting him.”</p>
+
+<p>“I am naturally lazy,” confessed Cole blandly, “and it would be too
+much of an exertion to carry the fellow out of here on my back.”</p>
+
+<p>“Have you a warrant for his arrest?”</p>
+
+<p>“None is needed,” said Cole easily, though he perceived that the
+conversation was taking a dangerous turn. “It is enough that I have
+reasonable cause for believing that the man has committed a felony.”</p>
+
+<p>His tone faltered slightly on the word “reasonable.” In his imagination
+he could picture the faces of the police officials, if he should
+undertake to tell them what had happened.</p>
+
+<p>Latham continued his piercing scrutiny for a few moments longer. “You
+looked to me like an impostor,” he declared. “I’ll wager you haven’t
+even so much as a pair of handcuffs on your person.”</p>
+
+<p>Cole jerked himself up straight in the chair. His twinkling eyes
+bespoke an inspiration. From his pocket he drew a small pair of steel
+links. “Small, but substantial,” he said musingly. “A friend gave them
+to me once. I have so little use for them that I wouldn’t carry them
+around except for the fact that they are so light and take so little
+space in the pocket. Once, in an unexpected pinch, <span class="pagenum" id="Page_139">139</span>they proved handy,
+and I have been carrying them ever since.”</p>
+
+<p>He got up and briskly walked into the room in the rear. A muffled
+exclamation escaped the doctor, as Cole fastened one of the links
+around the hunchback’s wrist. Then, with surprising ease, he lifted the
+man out of the chair and carried him to an operating table in a corner
+of the room.</p>
+
+<p>“What are you doing?” inquired Latham sharply, too amazed at Cole’s
+conduct to be able to interfere.</p>
+
+<p>A short laugh was Cole’s only answer. He stretched the unconscious man
+out on the operating table.</p>
+
+<p>“Are you crazy?” spluttered the doctor. “What——” He stopped short as he
+saw Cole’s intention, but now it was too late to act. Cole had placed
+the limp figure in such a way that the arm, from which the steel links
+dangled, was hanging down along the side of the table. In a twinkling
+he had fastened the other link around one of the iron legs. The
+unconscious man was now securely chained to the table.</p>
+
+<p>Cole turned and regarded the physician with a good-humored expression.
+“My round, and it’s as good as a knock-out,” he observed.</p>
+
+<p>Latham stared dumfoundedly. He saw what had happened, but he appeared
+at a loss to grasp the meaning of it. “What do you hope to gain by such
+tomfoolery?” he demanded.</p>
+
+<p>“A lot,” said Cole softly. “Your patient can’t get away unless he
+takes the table with him, and that would attract attention. A fleeing
+murderer is under quite a handicap when he is chained to an <span class="pagenum" id="Page_140">140</span>operating
+table. I notice it is all iron and strongly built. The legs are
+soldered to the top, so it won’t be easy to take it apart. A skilled
+craftsman could do it, but I believe you have a strong aversion against
+calling in outsiders.”</p>
+
+<p>The cold gleam in Latham’s eyes told that he understood. His gaze was
+fixed in a speculative way on the two steel links.</p>
+
+<p>“They could be filed off,” admitted Cole, guessing his thoughts, “but
+it would take a long time to get through the chilled steel of which
+they are made. An expert might be able to unlock them, but there again
+you are hampered by your prejudice against outsiders. You can’t slip
+the link off the iron leg, for the braces down below prevent that.
+Barring accidents, I think my man will stay here till I’m ready to come
+and get him.”</p>
+
+<p>Doctor Latham seemed a trifle dazed. He ran his fingers awkwardly
+through his beard while looking bewilderedly at Cole. “You are an
+astounding person,” he declared.</p>
+
+<p>“You are another, doctor.” Cole smiled engagingly. “Sorry to have
+interrupted your night’s rest. Are you going to charge me for this
+visit? I believe it was ten dollars last time.”</p>
+
+<p>“Go to blazes!” said Doctor Latham. He stood motionless beside the
+unconscious man, while Cole walked out of the room.</p>

+<h2 id="chap_XIII">CHAPTER XIII</h2>
+<div class="subheadc">THE MORNING’S MAIL</div>
+</div>
+
+<p class="drop-cap">JUST as the clock struck eleven, the following morning, Kingdon Cole
+emerged in a tingle and glow from his cold shower. He had retired
+shortly before dawn, so he had considered himself entitled to sleep
+till a late hour, and now he felt the exuberant strength and freshness
+that make a man eager for work.</p>
+
+<p>He stepped to the window, raised the shade, and looked out upon a gray
+and drizzly world. He scowled a little. Like all highly sensitized
+persons, he was easily susceptible to the weather. When the sky was
+clouded, his face was apt to wear a frown. When the sun shone, his face
+shone with it. A glance in the evening at the weather forecast could
+have told him what mood he was to be in the next day, granting that
+weather predictions were always accurate.</p>
+
+<p>He turned from the window as Toots, with a plaintive “meow,” rubbed her
+curled back against his leg. “Hungry?” inquired Cole, looking at the
+cat with an expression of grave responsibility.</p>
+
+<p>Toots held her tail erect and seemed to think the question wholly
+superfluous. With a dutiful air Cole brought in the milk bottle, also
+two letters which he found outside his door. After a glance at the
+handwriting he tossed them on the table and proceeded to appease Toots’
+hunger. He went about it with all the awkwardness of an overgrown boy,
+<span class="pagenum" id="Page_142">142</span>spilling a part of the milk beside the saucer, then stood aside and
+watched Toots lick it up.</p>
+
+<p>Over his coffee and toast, a few minutes later, he started to read
+his mail. One of the letters was addressed in a strange feminine
+handwriting, and he opened it first. He suddenly stopped eating and
+took in the contents at a glance. The note read:</p>
+
+<p>“Come back. I trust you.</p>
+
+<p class="right">
+ <span class="smcap">Miss B.</span>”
+</p>
+
+<p>Beneath the signature was a row of X’s. Cole counted seven of them;
+they were the insignia of The Unknown Seven, of course. It was
+gratifying to know that the mysterious Miss Brown still had faith in
+him, despite the suspicions of the other members of the organization,
+but her frankness puzzled him. If the others thought him guilty of
+duplicity, why did she not think likewise? She had seen and heard
+precisely the same things that the others had seen and heard. As far as
+he knew, she had no facts on which her favorable opinion of him could
+have been based. What, then, was the reason for her attitude?</p>
+
+<p>“Woman’s intuition, I suppose,” mused Cole with a glance at Toots.
+“That probably accounts for it. But how does the charming Miss Brown
+expect me to find my way back to the headquarters of The Unknown Seven?
+To locate the building would be about as ticklish a job as finding
+a needle in a haystack. I don’t see why she—— Yes, I do! She has
+naturally taken it for granted that I had sense enough to make a mental
+note of the street and number when I made my hasty exit last night. She
+doesn’t know what a half-cocked idiot I am. Shucks!”</p>
+
+<p><span class="pagenum" id="Page_143">143</span></p>
+
+<p>Cole made a wry face. Somehow he must manage to find the headquarters
+of The Unknown Seven. Unless he answered Miss Brown’s summons, she
+would naturally suppose that her faith in him had been misplaced and
+that he was remaining away because of a sense of guilt. Cole resolved
+he would canvass every block in lower Manhattan before permitting such
+a thing to happen. How to go about it was another matter, however. A
+systematic search would eventually lead him to the building, but that
+would mean a waste of valuable time. He must find the headquarters
+of The Unknown Seven without delay, not only because Miss Brown had
+faith in him, but also for the more practical reason that he would not
+know what to do with the hunchback until he had positive knowledge of
+Malcolm Reeves’ death.</p>
+
+<p>He had no fear that his prisoner would escape from Doctor Latham’s
+house. He had left the hunchback in a predicament from which the
+astute physician would not be able to release him without a great deal
+of difficulty; but Cole did not depend on that alone. Tony Pinto, a
+ragged urchin whose habitat was the picturesquely squalid section
+around Chatham Square, was watching the doctor’s residence. Cole, who
+had earned the lad’s everlasting gratitude by once doing him a small
+service, had instructed him to keep a sharp eye on the place. Tony
+had the wits of a fox and the legs of a deer, and a great ambition
+to become a detective. If an attempt should be made to spirit the
+hunchback away, Tony would find it out and report to Cole instantly.</p>
+
+<p><span class="pagenum" id="Page_144">144</span></p>
+
+<p>Finishing his breakfast he lighted his pipe and composed himself
+for hard thinking. The tobacco smoke grew so thick in the room that
+Toots blinked at him reproachfully. Suddenly an idea came to him. He
+recalled having heard Grover Carlin say that a number of the members
+of The Unknown Seven had offices in the building. Cole had recognized
+several of the members, the previous evening, from photographs that had
+appeared from time to time in the newspapers, in connection with their
+social and financial activities. Right here was a clew to the location
+of the headquarters.</p>
+
+<p>He picked up the telephone directory and found the name of Vincent
+de Witte, one of the men whom he had recognized. He glanced at the
+financier’s office address, and he saw his clew slipping out of his
+fingers. The address was somewhere in Union Square, much too far north
+to be anywhere near the building he was searching for. Next he looked
+up the address of Stephen Aldrich, but with no more success. The
+philanthropist’s offices, according to the directory, were in the Times
+Square district.</p>
+
+<p>Cole tried two other names, then tossed the book away in disgust.
+It came to him that men like De Witte and Aldrich were engaged in
+multifarious enterprises and probably had two or more suites of
+offices in different sections of the city. Likely as not the business
+enterprises which they were conducting in the headquarters building
+were under corporate names, not generally known to the public. It was
+not to be expected that men so shrewd as The Unknown Seven had proven
+themselves to be <span class="pagenum" id="Page_145">145</span>would leave even the remotest clew to the location of
+their rendezvous. Cole saw he must try something else.</p>
+
+<p>He gazed hard into the monkey’s face graven into the bowl of his pipe.
+What with the drizzle outside and the chaotic condition of his mind,
+he scowled into the tobacco haze that surrounded him. Why the deuce
+hadn’t Miss Brown telephoned him instead of mailing him a letter?
+Why was it that women of her type were so prone either to underrate
+or overrate the intelligence of the sterner sex? They never accepted
+men at their true valuation, but their opinions were always colored
+by bias of one kind or another. Cole squinted at Toots while these
+thoughts ran through his mind. He had a distinct impression that that
+dainty specimen of femininity always regarded him with a sort of lofty
+tolerance. Miss Brown, on the other hand——</p>
+
+<p>Suddenly he remembered the other letter. At first glance he had
+recognized the cramped hand of Hector Englebreth’s secretary. He
+snipped off the margin of the envelope. Without doubt the letter
+contained a sharp reminder that Cole had promised to give his client a
+supplementary report on the condition of Malcolm Reeves. He anticipated
+a crisply phrased note as he drew out the inclosure. Then a surprise
+came to him. The envelope contained not only a letter, but a check
+besides. It was for a generous amount. Evidently his client had sent
+him something on account. Thoughtful of Englebreth! Cole put the check
+aside and glanced at the note, and then he received a second surprise.
+He read:</p>
+
+<p><span class="pagenum" id="Page_146">146</span></p>
+
+<p>“<span class="smcap">Dear Sir</span>: Mr. Englebreth desires me to notify you that he no
+longer requires your services. Inclosed please find check for services
+rendered to date.”</p>
+
+<p>Cole stared hard at the few typewritten lines. The stiffly worded
+communication was signed by Hector Englebreth’s secretary. The prim
+type and the severe plainness of the engraved name and address in the
+upper left-hand corner seemed to convey a breath of the heavy, tomblike
+atmosphere that pervaded the Englebreth house.</p>
+
+<p>He chuckled lightly as he flung the letter aside. It was not the first
+time that his independent conduct had lost him a client, and the fact
+that he was now cut off from all official contact with the Reeves
+mystery did not worry him in the least. There was nothing to prevent
+him from attacking the problem on his own account. The curt dismissal
+puzzled him, however. He wondered what he had done to displease
+Englebreth. His client’s warning, spoken just as Cole was leaving the
+somber old house the other day, flashed across his mind.</p>
+
+<p>“Be careful,” Englebreth had said.</p>
+
+<p>The words had had a cryptic sound. Cole had wondered at their meaning
+then, and he wondered now. Had Englebreth dismissed him because of
+his failure to heed a warning which he had not understood? Once
+before it had occurred to him that perhaps his client had learned,
+in some mysterious manner, of his relations with The Unknown Seven.
+Was that what had been in Englebreth’s mind when he uttered that
+strange warning? Did his client suspect that Cole was betraying him by
+conducting <span class="pagenum" id="Page_147">147</span>secret negotiations with an enemy? The idea did not seem
+very plausible, but he could think of no other solution. On the whole
+he felt Englebreth had treated him rather shabbily. He had worked
+hard and loyally on the case. The abrupt dismissal was, in reality, a
+reflection on his honesty. In his resentment he resolved to demand an
+explanation of his former client.</p>
+
+<p>He glanced dubiously at the telephone, recalling that on several
+occasions Englebreth had expressed a dislike to holding conversations
+over the wire, and he decided that an interview, face to face, would be
+more satisfactory. He poured out another saucerful of milk for Toots,
+and half an hour later he was ringing the doorbell of the Englebreth
+house on Fifth Avenue.</p>
+
+<p>The drizzle and the leaden sky conferred an added touch of melancholy
+upon the dismal mansion. The chill, which he always felt on entering
+the house, had a keener edge this time. The rooms, with the window
+shades lowered as always, seemed darker and more oppressively silent
+than usual. The manservant who admitted him regarded him with an air of
+thinly veiled suspicion.</p>
+
+<p>“I’ll see if Mr. Englebreth is at home, sir,” he announced. His feet
+made no sound as he crossed the thickly carpeted floor and passed
+through a door that turned silently on its hinges. In a few moments he
+was back. “Mr. Englebreth is not at home,” he declared, dropping the
+habitual “sir.”</p>
+
+<p>Cole got up from his chair and gave the servant a playful poke in the
+ribs. It was a grotesque <span class="pagenum" id="Page_148">148</span>piece of levity in that house of frigid
+dignity, but he could not resist the temptation.</p>
+
+<p>“You’re a cheerful liar,” he told the man. Then, while the servant
+gaped after him in a scandalized way, he strode to the door of the
+library and pushed it open. In his wheel chair, beside the black walnut
+table, sat Hector Englebreth. A faint color tinged his white face as he
+saw the detective.</p>
+
+<p>“Good morning, Mr. Englebreth,” said Cole genially, and he drew up
+a chair and sat down. “I know that ‘not at home’ is a polite way of
+saying ‘get out,’ and so I walked right in. Hope you don’t mind.”</p>
+
+<p>Englebreth leaned forward in the chair and scowled forbiddingly. His
+long white fingers beat a restless tattoo on the table. “Why have you
+come?” he demanded. “Did you not receive my letter?”</p>
+
+<p>“I did, and the check, too. Many thanks. The check was quite
+satisfactory, but the letter left too many things unsaid. I am here to
+ask you why I am being fired off the job.”</p>
+
+<p>Englebreth glanced meaningly at the door. Instead of the long dressing
+gown which he usually wore, he was dressed in a suit of plain gray.</p>
+
+<p>“I shall be going out in a few minutes,” he declared stiffly.</p>
+
+<p>“It won’t take you long to answer my question. Don’t you think I am
+entitled to an explanation?”</p>
+
+<p>“Of course, if you insist. I instructed my secretary to write you after
+I had consulted my wife about the matter. Since it is her brother’s
+life that is at stake, she is more vitally concerned than I am, <span class="pagenum" id="Page_149">149</span>so I
+thought it only proper that she should have her say. After I had placed
+certain facts before her, she agreed with me that your usefulness to us
+is past.”</p>
+
+<p>“Certain facts? What were they?”</p>
+
+<p>“I think you know,” said Englebreth in a hard, dry tone. His deep-set
+eyes, oddly brilliant in contrast to his pale face, regarded Cole
+accusingly. “I am disappointed in you, Mr. Cole. You impressed me as an
+upright, honest man, and I had hoped for better things from you. One of
+the harshest experiences in life is the discovery that one has placed
+his trust in a person who isn’t worthy of it.”</p>
+
+<p>Cole’s face hardened, and there was an ominous gleam in his eye. “I
+think you had better explain that statement, Mr. Englebreth,” he said
+with slow emphasis.</p>
+
+<p>Englebreth shrugged. “You are not candid with me. You know quite well
+what I mean, so why pretend? For instance, can you look me straight in
+the eyes and tell me that you gave a full and truthful report when you
+were here the other day?”</p>
+
+<p>“It was truthful,” said Cole, “and as complete as I could make it under
+the circumstances. If I did not tell quite all I knew, it was because I
+was uncertain in regard to some of the facts.”</p>
+
+<p>A wraith of a smile twisted Englebreth’s thin lips. “And what about the
+warning I gave you? I hoped it would serve as a hint that I was aware
+of certain mysterious movements on your part. Why did you disregard it?”</p>
+
+<p>A long silence ensued. Each man gazed sharply <span class="pagenum" id="Page_150">150</span>into the other’s eyes.
+There was a glint of steel in Cole’s, a look of stern reproach in
+Englebreth’s.</p>
+
+<p>“Well?” said the invalid. The pale, mirthless smile was still hovering
+about his lips. “What have you to say, Mr. Cole?”</p>
+
+<p>“You have been spying on me evidently?”</p>
+
+<p>“You are using an unpleasant word. I have merely verified certain
+suspicions that concern you. I have also discovered certain facts which
+you have seen fit to conceal from me, facts which have a direct bearing
+on the fate of my brother-in-law. I don’t think there is anything
+further to be said.”</p>
+
+<p>Cole got up. He could not understand where, or by what means, the
+invalid had obtained his information, but it was evident that
+Englebreth’s mind was made up, and that no amount of argument could
+make him change his views.</p>
+
+<p>“You are wrong, Mr. Englebreth,” he said evenly. “A lot of queer things
+have happened, things I don’t understand myself. But, believe it or
+not, I have played fair with you from beginning to end. Some time
+before long I hope to prove it to you.”</p>
+
+<p>“Indeed!” said Englebreth. “I am sure it will be interesting.”</p>
+
+<p>His tone and the smile that accompanied the words made Cole
+instinctively clench his fists. Then he turned away, before his anger
+should get the better of him, and hurried from the house. Out in the
+drizzle and under the gray sky he shook off his resentment and laughed
+at himself. It was ridiculous that a peevish old invalid should make
+him lose his temper. Some day, when he had probed the Reeves affair to
+the bottom, he would <span class="pagenum" id="Page_151">151</span>make Englebreth eat his words. Just now he had
+more important things to consider than the aspersions of an infirm old
+man.</p>
+
+<p>He crossed the street and was about to board a bus when he chanced
+to look back and saw a large car draw up in front of the house. A
+moment later the massive front door opened, and two servants appeared,
+carrying Englebreth between them. They assisted him into the car, and
+Cole gazed speculatively after the vehicle, as it glided away down
+Fifth Avenue. It was a rare thing for Englebreth to venture beyond
+the gloomy confines of his house, and Cole wondered where he might
+be going. Perhaps he was about to get into touch with his mysterious
+source of information. In that case Cole might learn a great deal by
+following him.</p>
+
+<p>“Taxi, sir,” said a voice, and a cab slowed down at the corner where he
+stood. Cole’s hesitation lasted only a moment longer.</p>
+
+<p>“Follow that green car over there,” he directed. The chauffeur nodded,
+and Cole jumped in. The pursuit proved long and devious; again and
+again Cole chided himself for wasting valuable time. Then the green car
+stopped in front of an office building, and the chauffeur went inside.
+Cole dismissed the taxi and took up a position across the street. From
+where he stood he could catch an occasional glimpse of Englebreth
+through the partly shaded window of the car.</p>
+
+<p>“Guess I’m chasing a wild goose,” he glumly told himself.</p>
+
+<p>Englebreth’s chauffeur reappeared, accompanied by another man, and
+the two lifted the invalid from <span class="pagenum" id="Page_152">152</span>the car and carried him inside the
+building. Slowly Cole started to cross the street. The man assisting
+the chauffeur seemed to carry his part of the burden awkwardly, and
+Cole could hear the infirm man’s peevish protests. The two men entered
+an elevator with their load, and the cage started upward, just as Cole
+stepped inside the building.</p>
+
+<p>A strange, unaccountable feeling came over him as he gazed after the
+disappearing lift. He was conscious of a faint tingling from head
+to foot. With an abstracted look in his eyes he gazed upward, then
+to the sides. He moved about along the row of elevators, and even
+his footfalls had a curious sound, a sound that he seemed to vaguely
+recognize. The elevator starter approached and inquired what he was
+looking for, but Cole only shook his head in a preoccupied way.</p>
+
+<p>Suddenly he laughed aloud. In a twinkling all his confused impressions
+clarified. Once more he glanced upward. He knew, though he could not
+tell why or how, that far overhead was the rendezvous of The Unknown
+Seven.</p>

+<div class="subheadc">COLE’S RUSE</div>
+</div>
+
+<p class="drop-cap">COLE’S conviction that he had found the building occupied by The
+Unknown Seven was a matter of instinct rather than reason. He felt that
+once before, and not so long ago, his feet had trod the squares of
+stone that composed the floor. The surroundings had a remotely familiar
+appearance; perhaps he had subconsciously caught a glimpse of them as
+he rushed out in pursuit of the hunchback. Along the wall opposite the
+elevators was a row of small shops, a cigar store, a haberdashery, a
+news stand, and, on the corner, the office of a broker. Cole glanced at
+the signs, and they stirred hazy recollections in the back of his mind.</p>
+
+<p>There could be no doubt of it; chance and Mr. Englebreth had led him to
+the very place he had been most anxious to find.</p>
+
+<p>On the wall in the back was a directory of the tenants. “Security
+Building” it said at the top, and the very name smacked of
+conservatism, stability, and decorum. It spelled efficiency and prose
+and left the imagination untouched. It hinted of things far removed
+from the secret activities of the group of strange men who occupied
+the top floor. He ran his eyes down the names of corporations and
+individuals, but there was none that interested him. Among the former
+were probably several in which members of The Unknown Seven were
+concerned, but he had no means of identifying them.</p>
+
+<p><span class="pagenum" id="Page_154">154</span></p>
+
+<p>He turned away and grinned sheepishly, as he noticed that the elevator
+starter was squinting at him in a suspicious way. There were five
+elevators, but, after he had seen them all come up and down, he knew
+that none of them was the automatic one used privately by the members
+of the organization. For a time he was puzzled. At the farther side
+of the shaft was a door marked “Private,” and beyond this a flight of
+stairs. No doubt they were the same stairs he had rushed down the night
+before, after stopping his dizzy descent at the second floor.</p>
+
+<p>But it was the door between the stairs and the shaft that claimed his
+interest. The single word, “Private,” stenciled in black letters on a
+golden-brown surface, piqued his curiosity. It was plainly a hint to
+strangers to keep out. Signs of that kind had held a strong fascination
+for Cole ever since he was a boy. It was just as if some one had dared
+him to pass through the forbidden door. He tried it furtively, though
+well aware of the starter’s oblique scrutiny. It was locked, as he
+had expected, but the word, “Private,” continued to tantalize him.
+What could be on the other side of the locked door? The office of the
+superintendent of the building, perhaps. Or, maybe, the establishment
+of a mail-order concern that did not care for personal relations with
+its customers. On the other hand it might be only a storeroom where the
+scrub women kept their mops and brooms and buckets. All these guesses
+seemed plausible enough, but Cole strongly suspected something entirely
+different. Unless he <span class="pagenum" id="Page_155">155</span>were greatly mistaken, the door was the entrance
+to the private elevator.</p>
+
+<p>Wishing to verify his surmise, he walked up to the starter and, in a
+tone which might have signified that he was an agent for the building
+department or the inspector of an insurance company, inquired by whom
+the private door was being used.</p>
+
+<p>“A bunch of nuts,” said the starter, moved to loquacity by Cole’s
+official air. “They come an’ go at all hours. They’s some big bugs
+among ’em, too. Guess they belong to wunna them secret societies.”</p>
+
+<p>Cole tried to learn more, but the man became suddenly tight-lipped
+and referred him to the superintendent of the building for further
+information. “It’s agin’ my orders to talk about the tenants,” he added.</p>
+
+<p>Cole nodded understandingly and stepped aside. The locked door seemed
+to bar further progress for the present. Just then he remembered his
+original errand. He had almost forgotten Englebreth. The cage into
+which he had seen the invalid carried had just reached the ground
+floor and was disgorging passengers. Cole waited till it was ready to
+make another trip, then stepped in and slipped a small bill into the
+operator’s hand.</p>
+
+<p>“You carried up a crippled person some ten or fifteen minutes ago,” he
+said in an undertone. “Where did he go?”</p>
+
+<p>“Oh, him!” The operator grinned as he stuffed the bill into a pocket.
+“He comes here every now and then. You’ll find him in 2512, sir. It’s
+the top floor.”</p>
+
+<p>Cole got out on the twenty-fifth floor. To all <span class="pagenum" id="Page_156">156</span>outward appearances
+it was, indeed, the top floor of the building. The elevator shaft
+terminated in a blank ceiling, and the stairs in the back extended no
+higher. It was somewhat tantalizing to know that directly above him,
+and yet completely out of reach, was the rendezvous of The Unknown
+Seven.</p>
+
+<p>Cole paused outside the door numbered 2512, but he did not knock.
+He could think of no pretext for seeking another interview with
+Englebreth. The office, as was indicated by the sign on the frosted
+glass, was occupied by the Bureau of Civil Research, and he made a
+mental note of the fact. He could see no particular significance in
+Englebreth’s visit to a place of that kind. No doubt the Bureau of
+Civic Research was one of the numerous activities that his former
+client cultivated as a hobby. As far as his original purpose was
+concerned it looked as though Cole had wasted his time, but there was
+consolation in the fact that he had incidentally found the headquarters
+of The Unknown Seven. For the moment, however, he did not see how he
+was to profit by his discovery.</p>
+
+<p>He descended, cast a mildly baffled glance at the private door, and
+went out to lunch. It seemed as if there was nothing for him to do but
+loiter in the vicinity of the building and wait for one of the members
+to appear. Idleness irked him, however, and he disliked the thought
+that such a small thing as a locked door was standing in his way. He
+cudgeled his brain for an idea, as he strolled out of the restaurant.</p>
+
+<p>Suddenly he found one, and he walked two blocks and ducked into a
+subway entrance. Soon he was <span class="pagenum" id="Page_157">157</span>aboard an uptown train, bound for Doctor
+Latham’s residence. He suspected that in the pockets of the hunchback
+he would find a key that would unlock the door. If his guess had been
+correct, and the door opened into the elevator used by The Unknown
+Seven, then the hunchback must have passed through that very door the
+previous night. He could not have done so unless he had a duplicate
+key. He might have thrown it away, of course, but the chances were that
+it was still in his possession.</p>
+
+<p>Cole looked sharply about him as he walked down the block in which the
+doctor resided. He knew Tony was lurking somewhere in the neighborhood,
+but the youngster had a surprising knack at making himself
+inconspicuous when the occasion demanded it. He rang the doctor’s
+doorbell and was told by the white-capped attendant who admitted him
+that the physician was engaged with a patient. Cole waited in the
+reception room. Evidently Latham did not permit his other enterprises
+to interfere with his practice, for several patients were waiting to
+consult him.</p>
+
+<p>Presently the door opened, and the doctor arched his brows as he saw
+Cole in the waiting group. After a moment’s hesitancy he motioned him
+to enter the consulting room.</p>
+
+<p>“How is the patient, doctor?” inquired Cole briskly, glancing at the
+door in the rear.</p>
+
+<p>Latham stroked his glossy beard. “As well as can be expected,
+considering the awkward position you left him in. He has difficulty
+getting about.”</p>
+
+<p><span class="pagenum" id="Page_158">158</span></p>
+
+<p>“Then you have not yet succeeded in extricating him from his
+embarrassing predicament?”</p>
+
+<p>“Oh, no!” said the doctor with a dry laugh. “I haven’t even tried. I
+just removed him to one of the spare bedrooms upstairs. He was in the
+way down here. You wish to have a talk with him, I suppose? I fear it
+is impossible. He grew hysterical a while ago, and I had to give him a
+sedative.”</p>
+
+<p>“It doesn’t matter. I just want to look at him.”</p>
+
+<p>Latham gave him a queer glance, then he smiled knowingly. “I see,” he
+murmured. “You wish to make sure that he hasn’t escaped, despite the
+handicap you imposed on him. This way.”</p>
+
+<p>He opened a door and preceded Cole up a flight of stairs. They entered
+a room, and Cole saw the hunchback stretched out on the operating table
+and sound asleep. The physician watched him narrowly as Cole stepped
+up to the recumbent man and began to explore his pockets. A blank look
+came into the doctor’s eyes when Cole, with a murmur of satisfaction,
+extracted a key.</p>
+
+<p>“As I observed once before,” said Latham, “you are a most astounding
+person. I wonder what the significance of that key might be.”</p>
+
+<p>“Every key has a mission, doctor, and that is to unlock some door.”</p>
+
+<p>The physician regarded him thoughtfully. “I don’t understand you at
+all. You do such unexpected things. I am still wondering what your
+intentions are with respect to my patient.”</p>
+
+<p>“For the present my only concern is that he shan’t get away.”</p>
+
+<p><span class="pagenum" id="Page_159">159</span></p>
+
+<p>The doctor pondered for a few moments longer, then he shrugged his
+shoulders, and the two men walked down the stairs in silence. As they
+reached the consultation office and were about to pass into the outer
+room, Latham paused with his hand on the doorknob. “Would it surprise
+you very much,” he asked in slow, incisive accents, “if I were to tell
+you that I am just as anxious as you can possibly be that the fellow
+upstairs shan’t get away?”</p>
+
+<p>Cole’s eyes opened wide. “No, it wouldn’t surprise me. I would simply
+be unable to follow you. You are a deep one, doctor; nothing that you
+could say or do would startle me.”</p>
+
+<p>Latham’s face relaxed in a smile. “I construe that as a compliment.
+Please appease my curiosity on one point. You have taken extraordinary
+precautions against my patient escaping, but what about myself? Aren’t
+you afraid that I might run away?”</p>
+
+<p>“I am not,” said Cole emphatically. “You are not the kind that runs
+away. You work by subtler means than that. Where men of coarser
+mentality would kill an undesirable person, you merely render him
+harmless. If, later on, it should prove absolutely necessary to remove
+him, you hire another man to perform the nasty job. Your sensitive soul
+shrinks from vulgar tactics and sordid actions. For the same reason you
+don’t run away from danger. Instead, you plan your moves so carefully
+in advance that the risk is reduced to the lowest possible minimum, and
+flight becomes unnecessary.”</p>
+
+<p>It was a rather blunt speech, and Cole had spoken so plainly only
+because he wished to watch the effect on the doctor. In the end he
+was disappointed. <span class="pagenum" id="Page_160">160</span>The expansive beard concealed all outward signs of
+emotion; the face was no more expressive than a wooden image. For just
+a moment the eyes shone with a cold gleam, but that was all. When Cole
+had finished, the bearded lips parted in a pleased smile.</p>
+
+<p>“Thanks,” murmured Latham. “Too bad we appear to be enemies. I like you
+immensely—I really do.”</p>
+
+<p>He held the door open and Cole went out. As he walked toward the subway
+he was almost inclined to share the doctor’s regret that they were
+enemies. There was something at once attractive and repellent about
+Latham. His subtleties, his cool audacity, and his flashing wits made
+him a charming personality, and there was a certain fascination even
+about his cold cynicism and conscienceless manner. Cole came away from
+the doctor’s house with a spell hanging over him. But, aside from these
+things, there were phases of Latham’s character that he could not
+understand. Stray remarks, which the doctor had dropped, and certain
+telltale gestures and mannerisms lingered in his memory while he rode
+downtown.</p>
+
+<p>“A fascinating riddle and a highly accomplished villain,” was his way
+of summing up the doctor’s many-sided personality, as he got out of the
+subway and turned toward the Security Building.</p>
+
+<p>He entered and, key in hand, walked direct to the private door. The
+elevator starter gave him an astonished glance, but did not interfere.
+The key fitted easily. Cole opened the door and stepped in, then
+quickly closed it behind him. He was in <span class="pagenum" id="Page_161">161</span>a narrow cage, with a small
+electric bulb at the top. He looked about him in bewilderment, for
+there was no sign of any apparatus by which the elevator could be
+started. Carlin had told him that there was a peculiar mechanism that
+could be operated only by the initiated, but all Cole saw was a dial
+with figures along the rim and a knob in the center. It looked like the
+combination lock of a safe.</p>
+
+<p>He twirled the knob back and forth, but without result. He tried
+several different combinations on the dial, but the elevator refused
+to budge. With ingrained stubbornness he persisted in his efforts, but
+in the end he was forced to confess that the task was beyond him. He
+was on the point of getting out when a key grated in the lock. A moment
+later the door came open, and Miss Brown entered the cage.</p>
+
+<p>She started slightly as she saw him. Cole looked at her, and his frown
+melted. She was simply, but charmingly, attired in a tailor-made suit
+of some soft, gray material the name of which was not included in
+Cole’s vocabulary.</p>
+
+<p>“Oh, you came!” she exclaimed.</p>
+
+<p>“Yes, but I didn’t get very far.” Cole regarded her with a half
+humorous, half reproachful glance. Her plain little hat set off
+to perfection the lily-white complexion and the hair like ruffled
+sunshine. “How did you expect me to manipulate the contraption?”</p>
+
+<p>“I didn’t really expect you to,” she told him, while she whirled the
+knob back and forth a number <span class="pagenum" id="Page_162">162</span>of times. “In fact, I was sure it would
+stump you, but the others had their doubts on that point.”</p>
+
+<p>“I see,” said Cole dryly, as the cage rocketed upward. “If I had
+shown that I knew how to operate the mechanism I would have convicted
+myself of duplicity, and the suspicions of the others would have been
+confirmed. But don’t you see that a man who is clever enough to ferret
+out secrets while blindfolded would not betray himself so flagrantly?”</p>
+
+<p>There was a twinkle of mirth in her deep-blue eyes. “Clever men are
+often vain. You might have construed my note as a challenge to your
+dexterity. It wasn’t that, of course. It was only a test of your
+honesty.”</p>
+
+<p>“And now you are convinced?”</p>
+
+<p>“I was practically convinced before, but the others needed proof.”</p>
+
+<p>“What convinced you?”</p>
+
+<p>The blue eyes regarded him shrewdly, almost impersonally. Cole was
+reminded of a biologist watching a controlled experiment.</p>
+
+<p>“I am seldom mistaken in matters of that kind,” she said simply.</p>
+
+<p>The cage stopped. As they got out, Cole abruptly asked the question
+that had been uppermost in his mind all the time. “What about Reeves?”</p>
+
+<p>“Dead, stabbed through the heart. He was breathing his last when we
+found him.”</p>
+
+<p>Cole nodded grimly. Miss Brown’s words had merely confirmed something
+of which he had been practically certain. They had gone through the
+hidden door in the wall by this time and were now in the corridor. They
+passed several men who bowed <span class="pagenum" id="Page_163">163</span>respectfully to Miss Brown and cast hard
+glances at Cole. The woman opened a door, and they entered the large
+room with the filing cabinets and the glass globe, the room in which
+Cole had been the night before.</p>
+
+<p>At a desk, with iron-gray head bent over a stack of papers, sat Grover
+Carlin. The lawyer looked up as they entered, and a faint smile flitted
+across his rugged face and tempered the cold gleam in his eyes. “Glad
+to see you, Mr. Cole,” he said in measured tones. “I am also pleasantly
+surprised. Your abrupt departure, just after the murder last night,
+looked pretty bad.”</p>
+
+<p>“I was rather surprised that you didn’t try to stop me.”</p>
+
+<p>Carlin grinned apologetically. “No one thought of doing so until it was
+too late. Everybody, including myself, were stricken senseless by the
+murder. We couldn’t realize that such a thing had happened right here
+in our midst. It seemed unbelievable. All we could think was that you
+were——”</p>
+
+<p>“In cahoots with the murderer,” suggested Cole when the lawyer paused.
+“Well, I admit it looked strange. That murder was about as nervy a
+piece of rascality as I ever heard of. The fellow came here determined
+to carry out his purpose or die in the attempt. Doesn’t his reckless
+audacity and the ease with which he got into your establishment suggest
+something to your mind, Mr. Carlin?”</p>
+
+<p>“Oh, yes a number of things. It suggests that he had powerful
+influences behind him. The motive isn’t far to seek. The men
+responsible for <span class="pagenum" id="Page_164">164</span>the murder feared that Reeves might recover from the
+effects of the operation and divulge certain facts which would be to
+their detriment. They decided to prevent that by silencing him forever.”</p>
+
+<p>“What else?” asked Cole, eying the lawyer steadily.</p>
+
+<p>Carlin gave him a quizzical glance.</p>
+
+<p>“How do you suppose the fellow got in?” Cole went on. “Where did he
+get the duplicate key to the elevator door? How did he get hold of
+the combination that controls the mechanism? Who told him how to get
+through the wall? How do you explain that, after entering, he walked
+straight to the room where Reeves was? As you probably remember, we
+heard the cry only a few moments after the green light had flashed,
+showing that the murderer knew his way thoroughly.”</p>
+
+<p>Carlin gazed at him hard and long. “Well?” he asked at length.</p>
+
+<p>“Perhaps you still suspect me?” asked Cole lightly.</p>
+
+<p>“No.” The word came a little uncertainly. “I never really suspected
+you. I only had certain doubts about you, doubts which were natural
+under the circumstances. Your return here this afternoon speaks
+volumes. You would scarcely have come back if you had been playing us
+false. I feel I owe you an apology.”</p>
+
+<p>“It’s accepted,” said Cole with a laugh. “But apologies aren’t going to
+remedy matters. Mr. Carlin, there’s a traitor among you.”</p>
+
+<p>Miss Brown, seated near by, caught her breath. The lawyer thrust his
+head forward a little. “Impossible,” he said. “There was a traitor
+among <span class="pagenum" id="Page_165">165</span>us, as I explained to you, but we got rid of him. For all I know
+he may be dead by this time. I am ready to swear to the reliability of
+every man on our staff.”</p>
+
+<p>Cole seemed inclined to argue the point, but he desisted. His eyes
+twinkled a little, and he looked as though he were content to let
+developments prove the truth of what he had said.</p>
+
+<p>“There is one thing you haven’t explained, Mr. Cole,” said Miss Brown.
+“I am curious to know how you got into the elevator a little while ago.
+Where did you get the key?”</p>
+
+<p>“Oh, the key,” said Cole lightly. “Why, I found it in the murderer’s
+pocket.”</p>
+
+<p>Carlin and Miss Brown looked at him in speechless astonishment.</p>
+
+<p>“I seem to be telling things backward,” Cole went on. “After I left
+here early this morning I gave the fellow a chase and caught him. He’s
+a hunchbacked, dried-up wisp of a man, and as evil looking a specimen
+of humanity as I ever saw.”</p>
+
+<p>Carlin blinked his eyes bewilderedly and looked at Cole, as if he had
+just discovered some new quality in him.</p>
+
+<p>“And you—you caught him?” asked Miss Brown. “Where—how?”</p>
+
+<p>Cole explained, but only very briefly. There was a gleam of sly humor
+in his eye. Toward the end of his recital he did a strange thing. He
+finished it off with an embellishing touch that was not in strict
+accordance with the truth.</p>
+
+<p>“The best part of it all,” he said in casual tones, “is that I have
+the fellow’s confession in black <span class="pagenum" id="Page_166">166</span>and white. Like most of his kind he
+showed the yellow streak when he saw the game was up. Just how complete
+the confession is I can’t say, but it contains several interesting
+facts.”</p>
+
+<p>“Where is it?” said Carlin excitedly. “Have you got it with you?” He
+half rose from his chair, then sat down again.</p>
+
+<p>“No; it isn’t wise to carry such things on one’s person. No telling
+when you’re going to get knocked down and have your pockets picked. The
+confession is in a safe place. In due time I shall show it to you.”</p>
+
+<p>Carlin seemed inclined to ask questions, but Cole’s face showed plainly
+that he had said all that he intended to say for the present. The
+lawyer got up, walked around the desk and gave the other’s shoulder
+a vigorous slap. “You belong here with us,” he declared with blunt
+emphasis. “You’re just the man for the job. I was sure of it before;
+now I’m doubly certain. You’ve proven your fitness in forty different
+ways. Will you accept?”</p>
+
+<p>Cole’s eyes gleamed wistfully. His smile showed that the proposition
+appealed to him. “You aren’t offering me the position just because I
+wormed a confession out of the hunchback?” he asked guardedly.</p>
+
+<p>“By no means. We were ready to offer you the place a week ago, while
+you were sniffing around the edges of what you called the Carmody case.
+We need you, Cole. Think it over carefully. Consider the opportunities.”</p>
+
+<p>“I have considered them. I am strongly tempted to accept, especially
+since I am out of a job.” <span class="pagenum" id="Page_167">167</span>Cole gave a whimsical little laugh. “I
+forgot to tell you that Englebreth gave me my walking papers this
+morning. Do you care to take on a man who was fired by his last
+employer?”</p>
+
+<p>“You just bet we do!” Carlin extended his hand, and Cole gripped it
+vigorously. “This evening your appointment will be confirmed by the
+full board, and afterward we’ll introduce you to the members of the
+staff. There’s one matter that’s got to be settled immediately though.
+You’ve got a ticklish problem to solve right at the start, Cole.
+Something must be done about the body of Reeves.”</p>
+
+<p>Cole had already thought of that. He realized what a delicate position
+The Unknown Seven were in. The murder could not be reported to the
+police without jeopardizing the secrecy that, to a great extent, had
+been responsible for the organization’s success. Neither would it be
+easy to turn the body over to the proper authorities without imperiling
+the society’s seclusion. It was a knotty problem, and Cole considered
+it from all angles, while Carlin and Miss Brown showed him over the
+premises.</p>
+
+<p>Cole’s eyes grew wider and wider as he was conducted from room to
+room. On one side of the hall were the offices with their steel filing
+cases, huge nickel-plated safes, desks, typewriters, and even a
+rogues’ gallery, which Cole inspected with avid interest. One room was
+devoted to finger prints and the Bertillon system of identification.
+Adjoining it was a laboratory in which, as Carlin explained, the
+latest scientific discoveries were adapted to the requirements of the
+detective profession.</p>
+
+<p>They crossed the hall, and it seemed to Cole that <span class="pagenum" id="Page_168">168</span>he was entering
+a different world. This part of the establishment was given over to
+clubrooms, but they were more magnificent than any Cole had ever seen.
+There was a well-appointed gymnasium; a swimming pool in which clear
+water gleamed invitingly in a huge tank of marble; a library containing
+all the latest fiction and belles-lettres; a dining room, an art
+gallery, a pool and billiard parlor, and various cozy little nooks for
+the members.</p>
+
+<p>“You see, Mr. Cole, we believe in combining pleasure and comfort with
+work,” explained Carlin, when the tour of inspection was finished and
+they were back in the office from which they had started. “By the way,
+dinner will be served at six-thirty. You must stay and dine with us.”</p>
+
+<p>Cole agreed after a moment’s hesitation. His glance fell on the
+telephone at Carlin’s desk, and suddenly he seemed to remember
+something.</p>
+
+<p>“Perhaps you would like to use the telephone,” the lawyer suggested.
+“The switchboard is in an office on the tenth floor, and all incoming
+and outgoing calls are relayed through it. No chance of a call being
+traced, you see.”</p>
+
+<p>Cole picked up the telephone and gave the operator the number of his
+landlady. Carlin and Miss Brown started to withdraw, but Cole assured
+them there was nothing personal about the call and asked them to stay.</p>
+
+<p>“That you, Mrs. Armstrong?” he asked when he had got his connection.
+“Mr. Cole speaking. I may not be home till late this evening, and
+I wonder if you’d mind running up and giving Toots her milk. Yes,
+Toots—T-o-o-t-s. The cat, you <span class="pagenum" id="Page_169">169</span>know. Very good of you. Will you do it
+right away, Mrs. Armstrong? I’ll hold the wire till you come back.
+Toots wasn’t looking well this morning. Acted as if she had a headache
+or something. I’m anxious to know how she is.”</p>
+
+<p>With the receiver at his ear, Cole waited. Carlin stroked his chin
+reflectively. From time to time he gazed in an odd way at the man who
+was to direct the activities of The Unknown Seven, and whose sole
+concern just now appeared to be an ailing cat. Miss Brown was amused
+and took no pains to conceal it.</p>
+
+<p>Cole was kept waiting a long time. At last he pricked up his ears in a
+startled way, as if some surprising news was being told him. He uttered
+a few short exclamations, then hung up the receiver and glanced at his
+watch.</p>
+
+<p>“Mr. Carlin,” he said gravely, in a tone so low that the other two
+could scarcely hear, “two hours ago I sat in this chair and told you
+a lie.” He made a silencing signal with his hand as Miss Brown and
+Carlin started to interrupt. “Yes, a lie. What I said about having
+wrung a confession from the hunchback wasn’t true, though all the
+rest was in strict accordance with the facts. As you may remember, I
+mentioned having put the confession in a safe place. From that you
+might have inferred that I had hidden it at my home, or placed it in a
+safe-deposit box.”</p>
+
+<p>He was speaking in whispers, as if afraid that an eavesdropper might be
+lurking somewhere in the room. The faces of his two listeners showed
+stark bewilderment.</p>
+
+<p><span class="pagenum" id="Page_170">170</span></p>
+
+<p>“That was two hours ago,” he went on, “and just now my landlady told me
+that when she went up to my rooms to feed the cat she found everything
+thrown topsy-turvy. The place looked as if a cyclone had struck it.”</p>
+
+<p>Miss Brown gave a little gasp. Carlin’s pupils contracted in
+astonishment. He stared hard at Cole, while a cloud overspread his
+face. One arm was stretched out on the desk, and his fingers clenched
+and unclenched spasmodically.</p>
+
+<p>“They didn’t lose any time,” he muttered. “I don’t understand, but you
+were right, Cole. There’s a traitor among us.”</p>
+

+<div class="subheadc">THE TRAITOR UNMASKED</div>
+</div>
+
+<p class="drop-cap">WITH his fingers across his lips, Cole enjoined silence. His glance
+darted quickly over the floor, the ceiling and the walls. He moved
+hither and thither, looking behind desks and filing cases. Finally he
+stepped behind Carlin’s desk and gazed speculatively at a panel of
+grille work in the wall. He held his hand before it and felt a strong
+draft of fresh air. It was obviously a ventilating shaft, and the force
+of the current suggested that air was driven into it by fans.</p>
+
+<p>He whirled round and whispered to Carlin and the girl. “Talk,” he said,
+“talk on any subject but the one you’re thinking on. Be as natural as
+you can.”</p>
+
+<p>Carlin showed plainly that he did not understand, but he nodded
+obediently. Cole tiptoed to a typewriter desk in the rear, and in one
+of the drawers he found a box containing a number of small tools.
+Selecting a screw driver, he went back to the air shaft and loosened
+several of the screws that held the grilled panel. In a few moments he
+could bend it outward, and now he inserted his hand and ran it up and
+down the sides of the shaft.</p>
+
+<p>“Any more of that sauterne left?” he heard Carlin ask the girl.</p>
+
+<p>“About a dozen bottles, I think.”</p>
+
+<p><span class="pagenum" id="Page_172">172</span></p>
+
+<p>“We’ll instruct the chef to have it served after the fish course. Just
+to celebrate the occasion, you know. Afterward——”</p>
+
+<p>The lawyer ran on with the dogged air of a soldier obeying orders that
+he doesn’t understand; but Cole heard no more. A sudden tensing of his
+body hinted that he had verified a suspicion. He had found a small
+metal disk attached to the opposite side of the air shaft, and to it
+was affixed a wire that extended upward. A serio-comic smile twisted
+his lips as he rejoined Carlin and Miss Brown. “Guess what I found,” he
+said in a whisper.</p>
+
+<p>The other two stared.</p>
+
+<p>“An amplifying disk and a wire that seems to run out on the roof. A
+dictaphone in other words. There may be others scattered throughout the
+place. My little ruse has shown that these walls have ears.”</p>
+
+<p>The lawyer was too astounded for words. Miss Brown looked fixedly at
+Cole, her lips trembling a little at the corners.</p>
+
+<p>“Did I hear you say something about sauterne?” asked Cole in his usual
+speaking voice, at the same time motioning them to step farther away
+from the shaft in which the disk was hidden. “Favorite drink of mine,
+though I take only an occasional drop of such things.” Again he lowered
+his voice. “To-night I shall get out on the roof and see where the wire
+runs to. Carlin, this is additional proof that there is a renegade
+in our midst. The man who posted the hunchback on how to get in here
+probably installed the dictaphone. It isn’t safe for us to make a
+single move until we have singled <span class="pagenum" id="Page_173">173</span>him out and rendered him harmless.
+We must attend to that even before we consider what is to be done with
+the body of Reeves.”</p>
+
+<p>Carlin still seemed a trifle dazed. “You are right, of course,” he
+said. “We must get rid of the blackguard at once. It is startling to
+think that any one in our organization may be the traitor. How are we
+going to find him?”</p>
+
+<p>“Leave that to me.” Cole’s narrowing gaze slanted upward, as if his
+thoughts were on the track of an idea. “I have noticed that a man of
+that kind nearly always has a flaw in him of some sort. Generally that
+flaw is cowardice. That gives us an advantage over him, right at the
+start. We’ll play on his cowardice and make him betray himself.”</p>
+
+<p>The lawyer looked somewhat dubious. “How?” he asked.</p>
+
+<p>“I haven’t studied out the details yet,” said Cole, but the slow
+twinkle in his eye told that the idea was assuming shape. “You sowed
+the seed of a plan in my mind when you mentioned sauterne. But don’t
+expect anything spectacular. Sometimes simple measures work best. Can
+you arrange to have the whole organization here for dinner?”</p>
+
+<p>The lawyer fingered his chin in a bewildered way. “It could be managed.
+Most of them have planned to attend, anyway.”</p>
+
+<p>“Splendid! Now, Carlin, since I am to take charge of the work here,
+it would seem only fitting that everybody should drink my health in
+sauterne, wouldn’t it?”</p>
+
+<p>“Cer—certainly,” stammered Carlin.</p>
+
+<p><span class="pagenum" id="Page_174">174</span></p>
+
+<p>“You could propose the toast yourself. I know you will do it
+charmingly. And I want you to see to it that everybody is invited to
+drink, including the waiters and the kitchen help. You could explain
+that the toast is to be a sort of pledge of allegiance.”</p>
+
+<p>The lawyer looked blinkingly at Cole, searching his face in vain for a
+sign that he was jesting.</p>
+
+<p>“I’m not sure there is enough sauterne to go around,” observed Miss
+Brown, who evidently shared Carlin’s stupefaction.</p>
+
+<p>“Then use smaller glasses,” suggested Cole. “Besides, in an emergency
+the wine can be thinned out. I think you said there were a dozen
+bottles. That ought to be enough for one round. I can almost taste
+that sauterne already.” He smacked his lips as he consulted his watch.
+“Carlin, I wonder if you would mind telephoning my landlady, Gramercy
+0099, to see if any messages have been received for me. The bright
+youngster who is watching Doctor Latham’s house may have been trying to
+reach me. In the meantime, Miss Brown, I am going to ask you to come
+with me to the dining room. I want to get a general idea of the seating
+arrangement.”</p>
+
+<p>With a long, wondering glance at Cole, the girl conducted him from the
+office, while Carlin cleared his husky throat in preparation for the
+task assigned him.</p>
+
+<p>“You are a very deep person, Mr. Cole,” the girl observed, as she led
+him into the dining room, where tables were set in horseshoe formation.
+“I <span class="pagenum" id="Page_175">175</span>have a suspicion that you are keeping a perfectly gorgeous scheme
+all to yourself.”</p>
+
+<p>Cole smiled thinly, while his glance roved over snow-white napery and
+brightly polished silver. At times Miss Brown had a naïveté about her
+that he found rather alluring.</p>
+
+<p>“I’ll take you into the secret in a few moments,” he promised. “One
+confidence deserves another, however. How much longer must I go on
+calling you Miss Brown?”</p>
+
+<p>“Don’t you like the name?”</p>
+
+<p>“I do not. I suspect you invented it on the spur of the moment the
+other night. It served well enough for a temporary acquaintanceship,
+but now its usefulness is past.”</p>
+
+<p>“True,” she admitted. “It was an awkward alias, anyhow. How do you like
+Merle Brownell?”</p>
+
+<p>“Much better. One syllable more or less makes a lot of difference at
+times. I take it you are the high priestess of The Unknown Seven?”</p>
+
+<p>“Oh, no! I’m only an odd-job expert. My father, who died three years
+ago, was the founder of the organization. I have hung around, more
+or less, ever since. Most of the time I suspect I am in the way, but
+occasionally I manage to make myself useful.”</p>
+
+<p>Cole regarded her with a look that seemed to say, “You’ll pass.”</p>
+
+<p>“You promised to take me into your secret,” she reminded him. “Aren’t
+you afraid? How do you know that I’m not the traitor, or traitoress?”</p>
+
+<p>“I know,” said Cole firmly, “but don’t ask me how I know. By the way,
+Miss Brownell,” and <span class="pagenum" id="Page_176">176</span>Cole lowered his voice several octaves, “I see the
+wineglasses haven’t been placed yet. Don’t you think you had better
+speak to the chef about the sauterne?”</p>
+
+<p>She gave him a puzzled look, then a roguish smile illuminated her
+face. “I’m beginning to think the sauterne is the chief ingredient in
+that brilliant idea of yours,” she declared, as she left the room. A
+few moments later Cole followed, turning toward the laboratory which
+Carlin had so proudly shown him. At one wall were several shelves on
+which bottles were placed in long rows. After studying the labels, Cole
+selected one of the bottles and put it in his pocket.</p>
+
+<p>Miss Brownell was supervising the placing of the wineglasses when he
+returned to the dining room. He stood aside and watched silently until
+the task was finished and the waiter had left the room. Then he took
+the bottle from his pocket and stepped to the table.</p>
+
+<p>“Please guard the door,” he told Miss Brownell, speaking in very low
+tones. “If any one wants to enter, keep him out on any pretext you
+like.”</p>
+
+<p>She watched him in astonishment while he went to work. The bottle
+contained a colorless liquid, and with great care he poured a few drops
+into each wineglass.</p>
+
+<p>“Are you going to poison us?” she asked. There was a secretive air
+about Cole that seemed to prohibit talking aloud.</p>
+
+<p>“No, the stuff’s harmless. Nothing but spirits of hartshorn. It will
+mix with the wine, but only a person with a very sensitive tongue will
+notice <span class="pagenum" id="Page_177">177</span>the queer taste. Such a person, if there should be one among us
+this evening, will notice that the wine has an odd flavor, but that’s
+all. He won’t be able to identify the added ingredient. The quantity is
+too slight.”</p>
+
+<p>“That makes everything very clear of course,” remarked Miss Brownell.
+“About as clear as mud.”</p>
+
+<p>Cole went calmly on with his work. “I suppose it has often occurred
+to you, Miss Brownell, that the imagination is a great aid to one’s
+senses. Tell a person there’s a fire in the next room, and he will
+instantly smell smoke, even though he may not have noticed it before.”</p>
+
+<p>“I don’t see what that has to do with what you are doing.”</p>
+
+<p>“A very great deal. When these glasses have been filled with wine, a
+person, taking a casual sip of the concoction, will not notice the
+queer taste. If he is told, after the second or third sip, that he
+has drunk poisoned wine, the peculiar taste will become noticeable at
+once. Without stopping to try to identify the queer flavor, he will
+instantly become convinced that he has been poisoned, especially if the
+circumstances are such that he already has reason to fear that some
+such thing is going to happen to him. That’s what imagination does to a
+person.”</p>
+
+<p>“Is this some kind of psychological experiment?”</p>
+
+<p>“In a way.” Cole had reached the last glass and was now putting the
+bottle in his pocket. “Incidentally it is interesting to note that a
+person with an uneasy conscience always has a lively imagination. Not
+only can he spot real dangers a <span class="pagenum" id="Page_178">178</span>mile off, but his guilty conscience
+is constantly surrounding him with imaginary ones. It’s a lucky
+thing, too. If it wasn’t for such frailties in the human make-up,
+we detectives would lose our reputation for achieving brilliant
+deductions.”</p>
+
+<p>Miss Brownell smiled soberly as they walked out. “I think we are
+going to have a most interesting dinner,” she murmured. “I hope your
+psychological experiment will succeed, Mr. Cole. I must run off now and
+powder my nose.”</p>
+
+<p>Cole slipped back to the laboratory and replaced the bottle. A few
+moments later he met Carlin in the corridor. The lawyer told him that
+he had called up Cole’s landlady, but no messages had been received for
+him.</p>
+
+<p>“That means Doctor Latham has made no move yet,” said Cole
+thoughtfully. “He plays a slow and sure hand.”</p>
+
+<p>The lawyer nodded. “Your landlady seemed quite distracted over the
+robbery,” he announced.</p>
+
+<p>“She isn’t the only one. I bet Toots is the most distracted female in
+the world, just now.” Cole gazed gloomily into space, and then a tall,
+broad-shouldered man approached with an easy swagger. Cole’s lips
+twisted into a reminiscent smile, as he recognized the surgeon.</p>
+
+<p>“Hello, Ballinger,” said the lawyer. “Shake hands with Kingdon Cole if
+you dare. I wouldn’t blame him if he were to shoot you on sight, but he
+has a forgiving disposition. Cole has just agreed to become one of us.”</p>
+
+<p>“Splendid!” ejaculated the doctor, and the two men shook hands. As
+their fingers touched, <span class="pagenum" id="Page_179">179</span>Cole experienced that indescribable something
+that comes from contact with a man of strong personal magnetism.
+Ballinger’s grip could not have been called energetic, but it
+transmitted a subtle electric current.</p>
+
+<p>“You are tackling a man-size job,” remarked the doctor after Carlin
+had withdrawn. “You will have a chance to match your wits against the
+infernal cleverness of the astutest rogue in the country. I suppose
+Carlin has explained the situation to you?”</p>
+
+<p>“He has only given me a few hints. There hasn’t been time for detailed
+explanations. All I know is that a colossal project of some sort is on
+foot, and that The Unknown Seven is trying to put a crimp in it.”</p>
+
+<p>Ballinger took his arm and led him to the smoking room. He extended
+his cigar case, and Cole noticed that his fingers were long, slim,
+and finely tapering, the fingers of one having a deft touch, a strong
+imagination, and a lively dramatic instinct. Again Cole saw that
+Ballinger’s resemblance to Doctor Latham was very slight, extending
+only to outward physique. It was the disguise, and the black beard in
+particular that had produced the likeness.</p>
+
+<p>“Too bad about poor Reeves,” murmured Ballinger, as he held a lighted
+match in his cupped hands. “His life, however, would have been only a
+burden to himself and others, so in one sense it is just as well that
+he was shuffled off. For professional reasons I regret his death very
+keenly. I had hopes of being able to restore his brain to <span class="pagenum" id="Page_180">180</span>some degree
+of normal functioning. If I had succeeded I think he would have told us
+a most interesting story, and that, of course, was just what the other
+side feared. However, his actions told us a great deal the other night.”</p>
+
+<p>“When he seemed to recognize Doctor Latham in you?”</p>
+
+<p>“Exactly. To that extent the experiment was a complete success. It was
+Carlin’s idea, and the credit belongs to him. I merely carried out his
+suggestions, and I didn’t particularly relish the task.” He chuckled
+apologetically. “Well, the murder of Reeves is additional proof of
+the fact that we are fighting a crowd of very ingenious and utterly
+conscienceless scoundrels. Evidently they are directed by a master
+mind, a genius of the kind we often read about, but seldom meet. You
+will admit there’s a great deal of fascination about a rascal of that
+type, Cole?”</p>
+
+<p>Cole did not answer, but he remembered the magnetic tug he had felt in
+Doctor Latham’s presence.</p>
+
+<p>“I almost envy you the exciting times you will have tracking this
+master mind to his lair,” Ballinger went on. “We know some of the
+smaller fry in the crowd, Professor Carmody, for instance, but our
+efforts won’t lead anywhere until we have found the directing genius.
+And when we have found him, Cole, we will be face to face with an
+interesting character. Brilliant, resourceful, unscrupulous, and full
+of bewildering subtleties, the kind that kills without hesitation the
+moment his plans are interfered with. I dare say you have already
+suspected who he is?”</p>
+
+<p><span class="pagenum" id="Page_181">181</span></p>
+
+<p>Ballinger’s eyes shone with a fine glow of enthusiasm, but it was the
+unimpassioned enthusiasm of a scientist who dissects and analyzes.</p>
+
+<p>“Perhaps,” said Cole guardedly. “Haven’t you?”</p>
+
+<p>Ballinger smiled queerly, but the opening of the door and the
+announcement that dinner was served forestalled a reply. In the
+corridor they were parted by a stream of people, and Cole found an
+opportunity to speak a few words in Carlin’s ear. The lawyer nodded
+bewilderedly, like one receiving instructions which he does not
+understand. He knew Cole had a plan of some sort, but he could not make
+even a guess as to what it was.</p>
+
+<p>There were some twenty-five or thirty at the table. Cole found himself
+seated between Miss Brownell and Carlin. Inwardly he felt a tingling
+sensation, as he contemplated the bombshell he was about to explode
+among the diners, but his face showed no sign of it. Now and then he
+stole a glance down the two wings of the table. He liked the faces of
+the men with whom he was to work. They were an alert, keen-eyed lot,
+the kind of men Cole himself would have selected.</p>
+
+<p>“You are a judge of faces,” whispered Miss Brownell, leaning slightly
+toward him. “Who is the traitor?”</p>
+
+<p>Cole shook his head. That very question had already occurred to him.
+There was not one in the gathering who by his looks could be singled
+out as the traitor.</p>
+
+<p>“Whom would you pick?” he whispered back.</p>
+
+<p>Her glance ran quickly up and down the table. He could see that her
+woman’s intuition was at <span class="pagenum" id="Page_182">182</span>work. A queer gleam came into her eyes; her
+face hardened for a moment. He tried to trace her glance, but it was
+too late.</p>
+
+<p>“It wouldn’t be fair to tell, would it?” she said evasively. “I may be
+wrong, you know.”</p>
+
+<p>Cole only smiled. As nearly as he had been able to tell, her glance had
+rested for an instant somewhere near the center of the left wing of the
+table. He scanned the faces of the men seated there, but none of them
+impressed him unfavorably, and he wondered what Miss Brownell could
+have based her guess on.</p>
+
+<p>The dinner progressed by easy stages, and the scene which Cole had been
+rehearsing in his mind was drawing near. Carlin, seated at his right,
+looked nervous, and Miss Brownell’s usually vivacious manner seemed
+somewhat dampened. Finally the sauterne was opened and the waiters
+filled the glasses. Carlin cleared his throat.</p>
+
+<p>Noisy applause greeted the lawyer’s announcement that Cole had
+accepted the management of The Unknown Seven’s activities. Then Carlin
+proposed a toast, and it was drunk standing. Cole watched the faces
+of the men as they quaffed their wine. In several of them he saw a
+vaguely wondering look, telling him that their senses had registered
+an impression so faint that as yet their minds had not grasped it. He
+sipped his own wine, and he wondered whether he would have been able to
+taste the foreign substance if he had not known it was there.</p>
+
+<p>When Carlin finished, Cole got to his feet amid renewed handclapping.
+Somewhat bluntly <span class="pagenum" id="Page_183">183</span>he thanked them for the ovation, and then he veered
+sharply to the subject uppermost in his mind.</p>
+
+<p>“I wonder,” he said, “how many of you can look me straight in the eye
+and tell me that you are loyal to this organization.”</p>
+
+<p>A breathless hush followed. His very quiet tones had created a profound
+impression. In the next instant every pair of eyes in the room was
+leveled at him without wavering.</p>
+
+<p>“It seems to be unanimous,” he observed dryly. “One can lie, however,
+with his eyes as well as with his tongue, and I know that one among you
+is a liar.”</p>
+
+<p>Another period of silence followed, and then came a scraping of feet
+and exclamations of incredulity. Cole held up a silencing hand. His
+eyes were everywhere, noting each shifting expression in the startled
+faces before him.</p>
+
+<p>“One of you has proven false to the organization,” he declared in
+short-clipped accents. “I discovered it only a little while ago. I
+found positive proof, not only of the treachery, but of the traitor’s
+identity as well. He is at this table. He was one of those who only a
+few moments ago looked me straight in the eyes. What shall we do with
+him?”</p>
+
+<p>Once more came an electric hush. Cole had spoken quietly, but with an
+emphasis that carried conviction. He smiled faintly, as he met the
+startled glances of the diners. A slight trace of the foreign substance
+in the wine was still lingering on his tongue.</p>
+
+<p>“What shall we do with him?” he asked again.</p>
+
+<p>“There’s only one thing to do with a traitor,” <span class="pagenum" id="Page_184">184</span>muttered some one at
+the farther end of the table, and the suggestion was followed by a
+chorus of approval.</p>
+
+<p>“And that thing has already been done,” declared Cole with grim
+emphasis. “So that it may serve as a warning to others who may be
+tempted to betray us, the traitor will die right before our eyes.
+Inside one minute the poison that was put into his glass will begin to
+take effect.”</p>
+
+<p>Cole pretended to look at his watch, but his glance was gliding swiftly
+over the two long rows of faces. He had spoken rapidly, and yet with a
+quiet insistence, putting his astounding announcement into the fewest
+possible words. The effect he hoped to produce depended upon a quick
+assault on the guilty person’s mental faculties, shocking him off
+his balance before he had time to digest the statement. In the acute
+tension of the moment, the vague impression that he had received while
+sipping his wine would suddenly crystallize, and then, with the fear of
+death upon him, he could not help betraying himself.</p>
+
+<p>At least such was the psychological effect Cole had intended, and he
+had been reasonably sure that the test would succeed. Moments passed
+while he stood, watch in hand, glancing out of the tail of an eye
+at the faces around the table. Sixty seconds passed, and a look of
+diffidence crossed his features. Here and there an impatient mutter was
+heard. Carlin was looking up at him with an expression of thinly veiled
+disappointment. At length Cole snapped the watch shut. He smiled rather
+sheepishly.</p>
+
+<p><span class="pagenum" id="Page_185">185</span></p>
+
+<p>“The trick didn’t work,” he said disgustedly. “Yes, I might as well
+admit it was only a trick. The traitor was too clever to betray
+himself.” With that he sat down, well aware that he had made an
+unfavorable impression.</p>
+
+<p>“It was too thin, Cole,” whispered Carlin in his ear. “Too bad you
+didn’t consult me beforehand.”</p>
+
+<p>Cole nodded dejectedly. Then he felt Miss Brownell’s gaze on his face.
+He turned and saw a knowing twinkle in her eyes.</p>
+
+<p>“It was very clever, Mr. Cole,” she whispered. But for all that her
+face indicated she might have given him only a consoling platitude.
+“You saw, of course?”</p>
+
+<p>“Yes, I saw enough.” The sheepish grin still lingered on Cole’s lips.
+“And you guessed right. The traitor is sitting near the center of the
+left wing of the table. Doctor Ballinger is a very astute rascal. It
+took him only a fraction of a second to see through my little bluff. He
+is smiling behind his palm this very moment. We’ll just let him keep on
+smiling for a while, eh, Miss Brownell?”</p>

+
+<p class="drop-cap">AFTER dinner Cole looked the picture of a man whose faith in himself
+has received a staggering blow. He seemed to take the outcome of his
+ruse very much to heart. He moved gloomily among the members of the
+organization, getting personally acquainted with a number of the men
+on his staff, and all the while he appeared to be making valiant, but
+not very successful, efforts to shake off his depression. Carlin did
+his best to gloss over the apparent frustration of the scheme, but Cole
+proved a hard man to console.</p>
+
+<p>Doctor Ballinger approached him after he had retired into a corner,
+and gave him a vigorous slap on the shoulder. “Don’t take it so hard,
+old man,” he said cheerily. “Know just exactly how you feel. It’s
+embarrassing to turn up a flivver right at the start, but don’t you
+mind. Better luck next time. Have a smoke.”</p>
+
+<p>“Thanks,” said Cole dejectedly, as he helped himself to a cigar from
+the doctor’s case. “What hurts me most is that I know I was right.
+Nothing is so humiliating to a man as to be sure of his facts and not
+be able to prove them. I know positively that there’s a black sheep in
+this fold. If I had worked the scheme properly——”</p>
+
+<p>“Tut, tut!” interrupted Ballinger. “Your scheme was all right in
+principle. You were simply out <span class="pagenum" id="Page_187">187</span>of luck, that’s all. The traitor, if
+you’re right in the assumption that there is such a creature among us,
+is probably a very slick customer. No doubt you had him scared stiff
+for a moment, but his emotional reaction didn’t last long enough for
+him to betray himself. He assumed that you were only bluffing. At any
+rate he saw that, having already drained his glass, nothing could be
+gained by making a show of himself. In other words his mind outstripped
+his emotions, and that’s where your psychology fell down. No matter!
+You’ll get him next time.”</p>
+
+<p>Cole walked away, a faint twitching at the corners of his lips. In
+the main Doctor Ballinger’s analysis had been correct. He had only
+forgotten to mention one little detail. Just as the traitor’s mind
+had outstripped his emotions, so had Cole’s alert glance outstripped
+both. For just an instant Ballinger had shown all the symptoms of acute
+terror. He had shaken them off with superb self-control, but not before
+Cole’s eye had registered his momentary confusion.</p>
+
+<p>The revelation that Ballinger was the traitor had given Cole a shock
+at first. The doctor was one of the last men in the organization whom
+he would have suspected of treachery. Having found him out, Cole saw
+no reason for apprising the doctor of the fact. He preferred to let
+Ballinger lull himself into a false security until he should show his
+hand more plainly. Neither did it seem advisable to Cole to take the
+other members into his confidence in regard to his discovery. It would
+be hard to keep a secret among so many, and the more hotheaded <span class="pagenum" id="Page_188">188</span>ones
+among them would probably demand drastic action.</p>
+
+<p>As inconspicuously as he could, Cole left the others and withdrew to
+the room that had been pointed out to him as his private office. It was
+small and comfortable and devoid of the drabness that characterizes
+the workroom of the average executive. There was a vase containing red
+roses on the desk, and he noticed that the pictures on the wall had
+been carefully chosen. He stretched himself out in the swivel chair and
+rocked in an experimental way. His glance fell on three white buttons
+affixed to the side of the desk. He pushed the one nearest him, just to
+see what would happen.</p>
+
+<p>The door opened, and in strode the biggest negro Cole has ever seen.</p>
+
+<p>“Who are you?” he inquired.</p>
+
+<p>“Sambo, sah.”</p>
+
+<p>“And what’s your job, Sambo?”</p>
+
+<p>“Just now mah bussiness is to answer dese heay bells, sah. Dat ain’t
+mah reg’lar job, though, but Rufus is done laid up in the hosspittle,
+and I’se takin’ his place.”</p>
+
+<p>“What happened to Rufus? Sick?”</p>
+
+<p>“Yas, sah. Mighty sick, sah.” Sambo grinned expansively. “You ought to
+know, boss, ’cause you made him sick yusself. Dat was an a’ful wallop
+you handed Rufus, sah.”</p>
+
+<p>Cole smiled reminiscently, as he recalled one of the numerous
+experiences that had enlivened his first visit to the establishment of
+The Unknown Seven.</p>
+
+<p>“Too bad about Rufus,” he remarked. “Now, <span class="pagenum" id="Page_189">189</span>Sambo, I want you to find
+Mr. McKendrick and ask him to come here at once.”</p>
+
+<p>“Yas, sah.” With a profound bow Sambo waddled out.</p>
+
+<p>McKendrick, one of the young operatives with whom Cole had chatted
+since the dinner, appeared after a brief wait. He had a clear eye, a
+whimsical expression about the mouth that had appealed to Cole on first
+sight, and a firmly molded chin.</p>
+
+<p>“Go into the main office,” Cole directed. “You will find a dictaphone
+in the ventilator shaft. The wire apparently runs out on the roof.
+Trace it to the other end, then report to me.”</p>
+
+<p>“Very well, sir.” As McKendrick walked out, Cole noticed with approval
+the easy swing to his shoulders. Once more he touched the nearest
+button, and Sambo appeared almost instantly.</p>
+
+<p>“Find Sloane and tell him I want him,” Cole directed.</p>
+
+<p>Sloane entered in a few moments. With his keen intellectual features
+and shell-rimmed spectacles he looked a good deal like a college
+professor.</p>
+
+<p>“Sloane,” began Cole, “I want you to go to the block in which Doctor
+Latham resides. Somewhere in the neighborhood, in a basement entrance
+across the street, perhaps, you’ll find a young chap of dilapidated
+appearance who answers to the name of Tony Pinto. He’s been watching
+the doctor’s house for the past twenty-four hours and must be sadly in
+need of food and sleep. Tell him I have sent you to relieve him.”</p>
+
+<p>“I understand perfectly, sir.”</p>
+
+<p>Cole gave him a few more instructions, and then <span class="pagenum" id="Page_190">190</span>Sloane withdrew. Again
+Cole pressed the button, this time to summon a man whom he instructed
+to make a thorough search all over the establishment for hidden disks
+and wires. When the man had gone, Cole leaned back in his chair and
+pondered. He had set the machinery in motion, but the hardest task he
+had reserved for himself. Something had to be done very soon about the
+body of Reeves. What to do with it was a problem that would demand all
+his resourcefulness. Too, a watch must be kept over Doctor Ballinger,
+and Cole did not like to delegate that business to any one else. He
+expected to learn a great deal from the unsuspecting doctor’s movements
+during the next twenty-four hours.</p>
+
+<p>He was deep in thought when a knock sounded on the door. In response to
+his rather brusque “Come in,” Miss Brownell entered.</p>
+
+<p>“I’ve been thinking,” she announced.</p>
+
+<p>“So I see,” said Cole, placing a chair for her. Miss Brownell, he
+observed, was one of the few women whom he had met who could wear a
+thoughtful frown becomingly. Where another woman’s forehead would have
+wrinkled, hers merely rippled.</p>
+
+<p>“You have been doing a lot of thinking yourself,” she remarked,
+regarding him with that curious impersonal glance of hers.</p>
+
+<p>“Yes, but mostly in the dark,” Cole admitted. “I’m pretty much in the
+same fix as the man who walks into a theater in the middle of the
+second act. The only thing that’s clear so far is that the principal
+actors in this drama seem to be doctors.”</p>
+
+<p><span class="pagenum" id="Page_191">191</span></p>
+
+<p>“You refer to Latham and Ballinger, of course. There is still another
+doctor involved.”</p>
+
+<p>“Still another? Who is he?”</p>
+
+<p>“In a sense he is the real instigator of the plot, although he died one
+hundred and thirty-eight years ago.”</p>
+
+<p>Cole blinked bewilderedly. “Sounds rather ghostly.”</p>
+
+<p>“His name was James Price, an English physician of high repute, who
+discovered a method of transforming baser metals into gold. You can
+read up on him in history or the biographical encyclopedias, if you
+like. He wrote a book entitled ‘An Account of Some Experiments,’ but
+it has been out of print a long time and copies are hard to obtain.
+Professor Carmody owns one of the few still in existence.”</p>
+
+<p>“Oh!” said Cole, elevating his brows. “So that’s what the mystery is
+about? But you don’t mean to tell me that sane men like Latham and
+Ballinger are dabbling in the exploded myth of alchemy?”</p>
+
+<p>“I do. And that myth, by the way, seems to die very hard, Mr. Cole.
+It’s been exploded and reëxploded since the dawn of history, and yet it
+keeps bobbing up every now and then.”</p>
+
+<p>Cole gave a little impatient shrug. “It’s rubbish,” he declared. “I
+have managed to forget most of the things I learned at school, but I
+seem to recall that modern science has absolutely established the fact
+that one element cannot be transformed into another.”</p>
+
+<p>She looked at him amusedly. “We women always smile when you men speak
+of absolute facts. The <span class="pagenum" id="Page_192">192</span>phrase is so delightfully characteristic of
+the sterner sex. And the world has moved since you went to school,
+Mr. Cole. Science has hedged and quibbled and reversed itself a good
+many times on the subject of the transformation of metals. It wasn’t
+so very long ago that some one discovered that radium can be produced
+from helium, or was it the other way round? Anyway, right there is an
+instance of the transformation of one element into another.”</p>
+
+<p>Cole opened his lips to speak, but seemed unable to find the right
+words.</p>
+
+<p>“I was telling you about James Price,” Miss Brownell went on. “He
+claimed to have discovered a method whereby he could transform sixty
+parts of mercury into one part of gold. He was rather secretive about
+his discovery and hedged it about with a lot of mystic hocus-pocus.
+About all that is definitely known is that a mysterious red powder
+figured prominently in the process. The red powder was mixed with
+mercury and fluid borax, and the concoction was then put in a crucible
+and stirred with an iron rod. The result was gold.”</p>
+
+<p>“The iron rod must have been a magic scepter,” suggested Cole dryly.</p>
+
+<p>“Perhaps; anyway the Royal Society of England got interested in Price’s
+experiments and made an investigation. A committee of England’s
+foremost scientists went to his laboratory, firmly expecting to expose
+Price as a faker or lunatic. I can imagine the long, bewhiskered faces
+of those learned old fogies when they put the gold through an assaying
+<span class="pagenum" id="Page_193">193</span>process and found that it proved genuine in every respect.”</p>
+
+<p>Cole’s pupils dilated a trifle, but he looked still dubious.</p>
+
+<p>“What I have told you is a matter of history, amply documented and
+supported by incontrovertible evidence,” declared Miss Brownell. “There
+can be no doubt but that Price produced a form of gold that proved
+genuine on assay. I am now coming to the strangest part of the story.
+Having solved this problem, that has tantalized scientific minds since
+the beginning of history, Price turned a sort of mental somersault.
+Just what happened to him has never become definitely known. Some
+still insist that he was a faker, despite the tests that were made.
+Others believe that his mind collapsed under the strain, and that he
+went insane. That seems to be nature’s way of punishing those who peep
+behind the curtain of the unknown, and Price was neither the first nor
+the last to go mad on the subject of gold. Still others think that
+gold became an obsession with him, a sort of monomania, and that he
+could not endure the thought of sharing his discovery with others. Then
+there are those who cling to the theory that his production of gold was
+nothing but an accident.”</p>
+
+<p>“What happened?” asked Cole.</p>
+
+<p>“The committee of scientists wanted to learn Price’s formula and asked
+him to repeat the experiment in their presence. Price refused on the
+pretext that his supply of red powders was exhausted. Shortly afterward
+he committed suicide by drinking laurel water. It has been generally
+<span class="pagenum" id="Page_194">194</span>supposed that his secret died with him. His book is somewhat vague
+in regard to the composition of the red powders. Repeated attempts
+have been made to learn exactly what they consisted of, but without
+success. Last year, however, Professor Carmody returned from abroad
+after browsing in the libraries of the Old World for many months. He
+brought back with him a number of faded and forgotten manuscripts, said
+to be in Doctor Price’s handwriting. Where he found them, and how he
+got possession of them we don’t know, but we do know that they gave him
+a clew to the secret which Price guarded so jealously.”</p>
+
+<p>“How do you know?” demanded Cole.</p>
+
+<p>“Our organization has eyes and ears everywhere. However, it was mostly
+through accident that we learned what was on foot. I shan’t bore you
+with the details. Carmody saw a chance to become enormously rich by
+manufacturing gold on a large scale, using Doctor Price’s formula. But
+he needed money to swing the enterprise, and so he guardedly approached
+a number of wealthy men with a scheme for multiplying their fortunes
+many times. Besides he knew that he lacked the executive ability
+required to engineer a project of such magnitude. He talked to Malcolm
+Reeves so engagingly that Reeves was smitten with the gold fever and
+supplied a great portion of the cash that he needed. No doubt he
+enlisted the assistance of other rich men in a similar manner. The lure
+of gold is a terrible thing, Mr. Cole.”</p>
+
+<p>“A curse,” said Cole. “But what about Latham?”</p>
+
+<p>“Latham is an extremely clever and very versatile <span class="pagenum" id="Page_195">195</span>man. Though he
+practices medicine he has dabbled in various sciences. Perhaps
+Carmody needed his assistance in solving some of the problems that he
+encountered in working out Price’s formula. However that may be, we
+know he has been very close to Professor Carmody for several weeks.”</p>
+
+<p>“Then you think Carmody is the moving spirit in the enterprise?”</p>
+
+<p>“No; Carmody merely supplied the formula and his scientific knowledge.
+He is a small man, physically and mentally, with a sharp, but narrow,
+intellect, and he is deficient in the qualities required to direct an
+enterprise of this sort. Knowing his shortcomings, he was willing to
+put the management of the project into stronger hands than his own.”</p>
+
+<p>“Latham’s, for instance?” asked Cole.</p>
+
+<p>“Or Ballinger’s. Both are very shrewd and energetic men, though I
+hadn’t thought of Ballinger in that connection until to-night. It is
+your job to find the master mind that is directing the operations of
+this gold-mad crowd, Mr. Cole. We know that they are already producing
+gold, or a substitute for gold, on a very large scale.”</p>
+
+<p>“Where?” inquired Cole quickly.</p>
+
+<p>“That’s another thing for you to find out. In some secluded spot in New
+York City or its environs there is a large and fully equipped plant.
+From snatches of conversation which we have overheard we know that it
+exists, but we haven’t been able to locate it. We also know that the
+conspirators feel confident that their product will stand every test,
+that it resembles natural gold in every respect. In order to eliminate
+all risk, however, they have <span class="pagenum" id="Page_196">196</span>decided to hold the gold in storage until
+the desired quantity has been manufactured. You can imagine what will
+happen when a golden flood is suddenly released and poured out over the
+country.”</p>
+
+<p>“A few men will become enormously rich over night, and the monetary
+system will be utterly disorganized. I suppose the ultimate result will
+be the worst panic the world has ever seen.”</p>
+
+<p>“That’s exactly what Mr. Carlin and the others think,” declared Miss
+Brownell.</p>
+
+<p>They sat silent for a time, neither looking at the other. Their minds
+were stunned by the contemplation of the golden havoc which their
+imagination pictured. Cole recalled the look of insane ecstasy which
+he had seen in Malcolm Reeves’ face. The words, “Pretty yellow,” which
+the insane man mumbled, suddenly assumed a vivid significance. He shook
+himself a little.</p>
+
+<p>“I suppose Reeves had a falling out with the others,” he remarked.
+“That’s why they first destroyed his mind and afterward killed him.”</p>
+
+<p>“Presumably.” Her eyes looked a little dim, as if they had gazed too
+long upon a dazzling vision. “It was about Reeves I was thinking
+just before I walked in here and disturbed you. I was wondering why
+Ballinger didn’t commit the murder. He had free access to the place and
+nobody had any suspicions against him. Why was it necessary to have the
+hunchback sneak in here and do it?”</p>
+
+<p>“I think the answer to that question is fairly clear.” Cole’s smile
+seemed to say that women, even the cleverest of them, were rather
+simple-minded at times. “The job had to be done by an outsider <span class="pagenum" id="Page_197">197</span>in
+order to conceal the fact that the conspirators had an associate in
+your midst.”</p>
+
+<p>“But they didn’t conceal it. The ease with which the hunchback got in
+and out proved clearly that he was assisted by some one on the inside.”</p>
+
+<p>“That’s so,” admitted Cole, somewhat abashed. “Well, then it’s quite
+likely that Ballinger balked at the job. Murder is pretty nasty
+business. It is a coarser crime than depriving a man of his reason.
+Many criminals of the intellectual type shrink from it.”</p>
+
+<p>“Maybe that was the way of it. There’s another thing that has been
+troubling me lately. Who do you think performed the operation on
+Reeves?”</p>
+
+<p>Cole stared at her for an instant. “It seems to be pretty well
+established that Doctor Latham was the man.”</p>
+
+<p>“Yes, I know that’s what they all seem to think. Their reason is that
+Reeves seemed to recognize Ballinger when he was made up to resemble
+Latham.”</p>
+
+<p>“It was more than recognition. The sight of Ballinger made up as Latham
+fairly terrified the poor man. I’ll never forget how he looked.”</p>
+
+<p>“But isn’t that a flimsy reason for supposing that Latham performed the
+operation?”</p>
+
+<p>Cole leaned out of his chair and regarded her closely, as if wondering
+whether her intuition was once more at work. “Can you imagine any other
+explanation for the way Reeves acted that night?”</p>
+
+<p>“Yes; can’t you?”</p>
+
+<p>Cole shook his head ponderously.</p>
+
+<p><span class="pagenum" id="Page_198">198</span></p>
+
+<p>“Just think about it,” she said, smiling faintly; then she rose and
+walked out of the room.</p>
+
+<p>For a long time Cole sat very still, with a thoughtful pucker across
+his forehead. Once, from force of habit, he reached for his pipe,
+frowning when he realized it wasn’t there. Now and then he bent a
+quizzical gaze on the chair which Miss Brownell had vacated.</p>
+
+<p>“What the deuce did she mean?” he mumbled. “What else is there to——”</p>
+
+<p>With a jerky motion he sat erect in his chair. He gave the desk in
+front of him a vigorous thump.</p>
+
+<p>“By Jove, she wins!” he declared. “There is another explanation. It’s
+beginning to look as though——” He checked himself, scowling. “But that
+only muddles the situation. What’s the good of an explanation that
+doesn’t explain. But I suppose a woman can’t see it that way. They’re
+all alike, from Toots down.”</p>
+
+<p>He shrugged as if to banish unprofitable speculations. He suddenly
+remembered that there had been weighty things on his mind when Miss
+Brownell interrupted his thoughts. He had given several orders to the
+men, and he had been studying what to do with the body of Reeves, and
+how he might make the most of his discovery that Doctor Ballinger was
+the traitor. He jumped from the chair as the physician’s name ran
+through his mind. For half an hour or more he had given not a single
+thought to Ballinger. He hurried from the office and crossed the
+corridor, but a glance into the smoking room reassured him. Ballinger
+was sprawled out leisurely in an armchair, evidently in <span class="pagenum" id="Page_199">199</span>the midst of
+an anecdote which he seemed to be relating with great gusto to his
+companion.</p>
+
+<p>Cole went farther down the corridor and rapped on the door to Miss
+Brownell’s private room. “Wish you would keep an eye on Ballinger for a
+while,” he whispered when she opened. She lifted her brows in a knowing
+way and nodded. In the main office he found Carlin bent over a stack of
+papers. The man seemed a veritable dynamo of energy.</p>
+
+<p>“I’ve been thinking about Reeves,” he said.</p>
+
+<p>Carlin looked up and took an obese cigar from his mouth. “What do you
+suggest?”</p>
+
+<p>“That we obey the spirit of the law and blink the letter. The ends of
+justice will be met if the murderer is convicted and punished. It won’t
+be necessary to drag all the embarrassing details into light.”</p>
+
+<p>“How can it be avoided?”</p>
+
+<p>“I have a plan, but, before I go any farther, I would like to see the
+body.”</p>
+
+<p>The lawyer got up. “I would have shown it to you when I took you over
+the place, but Miss Brownell was with us then, and you know how women
+are about such things.”</p>
+
+<p>He led the way from the room, and they went to the end of the corridor.
+There Carlin opened a door, and they stepped in. It was dark, and Cole
+could see nothing. He heard a slight scraping sound, as the lawyer ran
+his hand over the wall in search of a switch. Then a light flashed on.
+Carlin raised an arm and pointed.</p>
+
+<p>“There,” he said a trifle thickly, indicating a <span class="pagenum" id="Page_200">200</span>shape spread out on a
+cot at the farther side of the room.</p>
+
+<p>Cole walked up to the cot and looked down at the dead man. He jerked
+back a little as his glance fell on the lifeless face. Then he bent
+over the body and gazed fixedly into the rigid features. Finally he
+stood up and turned to Carlin, who had remained behind.</p>
+
+<p>“When did you last see the body?” he inquired, and his voice sounded a
+trifle husky.</p>
+
+<p>“Why, I think it was this morning. Yes, that was it, about ten o’clock
+this morning. Why do you ask?”</p>
+
+<p>“Because—— But see for yourself.”</p>
+
+<p>With a wondering glance at the detective, Carlin crossed the floor. He
+looked down at the motionless figure, and suddenly he shrank back a
+step. A husky exclamation sounded in his throat, then he slowly raised
+his eyes, and for a long moment the two men stared blankly at each
+other.</p>
+
+<p>“It—it isn’t Reeves!” stammered the lawyer.</p>
+
+<p>“No—it isn’t Reeves!” echoed Cole.</p>

+</div>
+
+<p class="drop-cap">COLE had recognized the dead man at a glance.</p>
+
+<p>It was McKendrick, the young operative whom he had instructed to trace
+down the dictaphone wire. That had been only an hour ago, and already
+death had blotted out the whimsical expression about the mouth that had
+attracted Cole to him from the first.</p>
+
+<p>“Shot through the head,” muttered Cole, noticing a crimson stain just
+above the left temple. “He hasn’t been dead more than fifteen or twenty
+minutes.”</p>
+
+<p>He turned and looked out through the crack of the open door. A laugh
+sounded in the direction of the smoking room. Perhaps Doctor Ballinger
+had just told another funny story. Cole closed the door.</p>
+
+<p>“This shows there are no limits to the rascality of those blackguards,”
+said the lawyer. “But I don’t see why they should kill McKendrick.”</p>
+
+<p>Cole explained the errand on which he had dispatched the young
+detective. “No doubt McKendrick made an important discovery of some
+kind,” he added. “That’s probably why he was killed. He must have been
+overpowered, either while getting his facts or on his way back here to
+report. Probably the latter; that would explain why the body was taken
+here. The murderer wanted to conceal his crime as long as possible, and
+for a <span class="pagenum" id="Page_202">202</span>temporary hiding place this room served as well as any other. We
+must find out whether Ballinger has been absent from the smoking room
+during the last hour or so.”</p>
+
+<p>The lawyer seemed dazed. “But the other body? What happened to it?”</p>
+
+<p>“You are sure it was here this morning?”</p>
+
+<p>“Positive.”</p>
+
+<p>“Could any one have taken it down the private elevator without being
+seen?”</p>
+
+<p>“Impossible. Even if such a thing could be done, which is unthinkable,
+it is a ticklish job to transport a body through the streets. It is not
+yet midnight.”</p>
+
+<p>“Is there any other exit?”</p>
+
+<p>“Only the stairs leading to the roof.”</p>
+
+<p>“Then it is a safe bet that the body of Reeves was taken out that way.
+From the roof it could have been slipped down a fire escape in the
+rear, and from there—Heaven only knows!”</p>
+
+<p>“But why should such a thing be done? What object could any one have in
+doing it?”</p>
+
+<p>“I don’t know, Carlin. I can only make a hazy guess. Being a lawyer
+you know better than I do that, with the body missing, it will be
+hard to prove the murder of Reeves. I believe the law covering murder
+cases provides that, when the <i>corpus delicti</i> cannot be proven,
+the commission of the crime must be established by direct, not
+circumstantial, evidence. Isn’t that correct?”</p>
+
+<p>“Substantially, yes.”</p>
+
+<p>“And, as I understand it, nobody saw the crime committed. Consequently
+there can be no direct <span class="pagenum" id="Page_203">203</span>testimony in regard to the murder. It appears
+that the men we are fighting are playing a very shrewd game.”</p>
+
+<p>The lawyer tried to pull himself together. “But isn’t it your idea that
+the men who instigated the murder of Reeves are also responsible for
+McKendrick’s death?”</p>
+
+<p>“Presumably?”</p>
+
+<p>“Then why, after going to all that trouble to cover up the first crime,
+did they leave the evidence of the second murder in plain sight?”</p>
+
+<p>“Looks a bit contradictory, doesn’t it?” Cole squinted abstractedly at
+the form on the cot. It seemed as though the murderers of McKendrick,
+in placing the body in the identical spot where that of Reeves had
+lain, had gone out of their way to add a spectacular touch to their
+crime. “But you may be sure of one thing,” he added. “They had good
+reasons for doing what they did. There isn’t any doubt——”</p>
+
+<p>He stopped short, and Carlin gave him a puzzled look.</p>
+
+<p>“Yes, that must be it,” Cole went on in an undertone. “The reason for
+what they did is to be found in the one thing that differentiates the
+murder of Reeves from that of McKendrick.”</p>
+
+<p>“And what’s that?”</p>
+
+<p>“Reeves was operated upon before he was murdered; McKendrick was not.”</p>
+
+<p>Carlin seemed unable to follow this line of reasoning.</p>
+
+<p>“If there should be an autopsy,” Cole explained, “it might be
+discovered that an atrocious operation <span class="pagenum" id="Page_204">204</span>had been performed on Reeves
+before his death. Such an operation could have been performed only by a
+skilled surgeon. It would be deduced that the operation and the murder
+were perpetrated by the same parties. That would reduce the range of
+suspicion down to one class of individuals, surgeons. So, you see, the
+body of Reeves constituted a clew to the identity of his murderers.”</p>
+
+<p>Carlin gave him an admiring glance. “First rate!” he applauded. “I’m
+glad you are doing the heavy thinking for us.”</p>
+
+<p>“You would have seen it yourself if you hadn’t been upset to-night,”
+said Cole modestly. “By the way, it’s just as well not to let the news
+of this fresh outrage get out among the men at present. Wish you would
+show me the stairs to the roof.”</p>
+
+<p>They left the room, and the lawyer locked the door. A short distance
+down the corridor they met Miss Brownell, and Cole recalled that he had
+asked her to keep an eye on the physician. Her lips tightened as he
+briefly whispered what had happened.</p>
+
+<p>“Do you know whether Ballinger was absent from the smoking room for any
+length of time during the last hour and a half?” he added.</p>
+
+<p>“He went out for cigars,” said Miss Brownell. “He explained that his
+case was empty, and he smokes only his special brand. When he returned
+he accounted for his long absence by saying that most of the cigar
+stores in the neighborhood were closed.”</p>
+
+<p>“That explanation is worthy of the doctor,” said Cole. “It’s plausible
+and yet simple. A more involved <span class="pagenum" id="Page_205">205</span>one might have got him into
+difficulties, if he should have been checked up on it afterward. Please
+watch him, Miss Brownell. If by any chance he should leave, have one of
+the men follow him. Now, Carlin.”</p>
+
+<p>The lawyer and Cole stepped into the main office. Suddenly Cole seemed
+to recall something. He went to the ventilator shaft which contained
+the dictaphone that had cost McKendrick his life. He touched the disk,
+and a low mutter escaped him as he found that the wire had been cut.
+About a foot and a half of it was dangling from the disk. He turned and
+told Carlin what he had discovered.</p>
+
+<p>“Something made them suspicious,” he added. “They cut the wire so we
+wouldn’t be able to trace it.”</p>
+
+<p>“They did that after murdering McKendrick,” suggested the lawyer.</p>
+
+<p>“Without a doubt. McKendrick, if he were alive, could probably tell us
+where the wire terminated. Now we will have a look at the roof.”</p>
+
+<p>But the door opened just then, and the man who entered was the
+operative whom Cole had instructed to search the establishment for
+hidden dictaphones. He reported that he had found four in as many
+different rooms, but in each instance the wires had been cut. Cole
+thanked him and dismissed him.</p>
+
+<p>“It’s a safe bet that all those wires were cut within the last hour or
+so,” he told the lawyer.</p>
+
+<p>Carlin led him to the farther end of the office. There he opened a door
+and indicated a steep flight of stairs. He was about to proceed up the
+stairs, but Cole held him back.</p>
+
+<p><span class="pagenum" id="Page_206">206</span></p>
+
+<p>“Wait, Carlin.” Cole took an electric flash light from his pocket and
+turned the gleam on the steps. They looked as if they had not been
+swept in a long while. He stooped low to examine a number of marks in
+the thick layer of dust. Drawing a magnifying lens from his pocket
+and slowly moving the electric torch up and down, he made a careful
+inspection of the lower steps.</p>
+
+<p>“Two sets of footprints,” he declared. “One set is fairly large and
+broad-toed, a number nine and a half shoe, I should say. The other
+is a size and a half smaller, also narrower. This tends to show that
+McKendrick was followed when he came down from the roof.”</p>
+
+<p>“Why do you suppose he was permitted to leave the roof?” inquired the
+lawyer.</p>
+
+<p>“Because the murderer couldn’t aim in the dark. He wanted to make a
+sure job of it. Probably McKendrick didn’t know he was followed down
+the stairs. Likely as not the shot wasn’t fired until he got down to
+the main office. It’s even possible the murder wasn’t committed until
+he was out in the corridor. That would explain why the murderer chose
+the room at the end of the hall as a temporary hiding place for the
+body. If the shooting took place in the corridor, he had to drag or
+carry it only a few steps.”</p>
+
+<p>Cole pocketed his flash and lens, and they started up the stairs.</p>
+
+<p>“But wouldn’t the shot have been heard?” asked Carlin.</p>
+
+<p>“Not if the weapon was equipped with a silencer. <span class="pagenum" id="Page_207">207</span>The smell of the
+burned powder was probably sucked up very quickly by the automatic
+ventilators.”</p>
+
+<p>Carlin opened a trapdoor overhead, and they stepped out on the roof. Up
+there all was wind and gloom. Their footsteps creaked dismally against
+the gritty surface. All around them loomed the ghostly shapes of tall
+buildings. Masses of clouds hung scowling over their heads, and there
+was a suspicion of moisture in the air.</p>
+
+<p>Cole stepped to the fire escape in the rear, the lawyer following. They
+looked down over the parapet into a wide court flanked by murky walls.
+“Yes,” said Carlin, more to himself than to his companion, “the body of
+Reeves was probably carried down this fire escape. It could have been
+done.”</p>
+
+<p>Cole nodded. “I wonder,” he said abstractedly, “how far down it was
+carried?”</p>
+
+<p>“Have you any reason for supposing that it wasn’t carried clear down to
+the ground?”</p>
+
+<p>“No, only a hunch, and most hunches are ridiculous. They go contrary to
+facts and logic. But just now I am more interested in what happened to
+McKendrick. He must have discovered something very important to warrant
+the scoundrels killing him. I wonder what it could have been.”</p>
+
+<p>“The other end of the wire, of course.”</p>
+
+<p>“Something more than that, I think.” Cole gazed down the long stretch
+of flights and landings that composed the fire escape. “Criminals of
+that type never kill without good cause. Not because they shrink from
+murder on moral or humanitarian grounds, but because it is dangerous
+and inexpedient. <span class="pagenum" id="Page_208">208</span>McKendrick must have discovered something that—— By
+the way, Carlin, I suppose The Unknown Seven controls the renting of
+offices in this building? You told me once that it is property of the
+organization.”</p>
+
+<p>“It is, but the members individually have nothing to do with the
+management of the building. That is handled through a separate
+corporation. Why do you ask?”</p>
+
+<p>“No particular reason. Those infernal hunches are bothering me more
+than usual to-night. Suppose you wait here while I investigate.”</p>
+
+<p>Before the lawyer could answer, Cole had flung himself over the parapet
+and was gliding down the fire escape with the agility of a chimpanzee.
+On the first landing he stopped and once more took out his electric
+flash and magnifying lens. Then he turned to the window and carefully
+examined the frame in the neighborhood of the fastenings. Tiny marks,
+that had a fresh appearance, told him they had been tampered with not
+so long ago. McKendrick, following the winding course of the dictaphone
+wire, had probably passed through this same window.</p>
+
+<p>In a few moments Cole was inside. Before him stretched a long hall with
+doors on either side; but the one to his left was the only one that
+interested him. He looked for a moment at the numerals 2512 and the
+lettering on the frosted pane. Once before in the past twelve hours the
+same sign had confronted him. While tracing Englebreth’s movements in
+the early afternoon Cole had come to this <span class="pagenum" id="Page_209">209</span>same door, and then he had
+turned back in the belief that nothing could be gained by going farther.</p>
+
+<p>“Bureau of Civic Research,” he read, wondering whether McKendrick had
+followed the course of the wire through this same door. Cole had no
+particular reason for thinking so, for at least twenty other doors
+opened into the same hall. Yet, in view of Englebreth’s apparent
+familiarity with Cole’s movements during the past few days, he could
+not help wondering. If the dictaphone wire had extended into suite
+2512, then the source of Englebreth’s information was clear.</p>
+
+<p>But the theory explained nothing else, and Cole had no proof that the
+wire had entered the office of the Bureau of Civic Research. His only
+clew was the scratches on the window frame, and they merely indicated
+that McKendrick had been on this floor. For all Cole knew, the young
+operative might have continued his search farther down.</p>
+
+<p>Yet the door continued to tantalize him. With a glance over his
+shoulder to see if perchance a watchman was near, he tried the knob.
+As he had expected, the door was locked, but he stooped and looked
+closely at the little circle of brass that formed the outer portion
+of the spring lock. The hall light was dim, so he once more took out
+his electric flash. Close to the center of the circle, just beside
+the keyhole, he saw a slight scratch. It was almost certain now that
+McKendrick had picked the lock and passed through the door.</p>
+
+<p>From his pocket Cole drew a bunch of carefully selected keys. Soon the
+door was open, and he walked in and quickly closed it behind him. Then
+<span class="pagenum" id="Page_210">210</span>he took out his flash, not thinking it safe to turn on the light, and
+made a swift inspection of the premises.</p>
+
+<p>There were two rooms, a larger and a smaller one. After a glance over
+the floor and walls, Cole’s face fell. The thing which he had vaguely
+and without much reason expected to find was not there. It was just
+an ordinary suite of offices, containing the ordinary set of office
+furniture. A glance into the filing cabinets left him in no doubt as to
+the bona-fide character of the Bureau of Civic Research.</p>
+
+<p>On one of the desks in the inner office were several typewritten
+letters. At the top of each sheet were printed the name of the concern
+and a list of its officers, and he noticed that Englebreth was
+mentioned as one of the honorary vice presidents. The letters had, in
+fact, been dictated by Englebreth, for in the lower left-hand corner
+of each one were the initials HE-MS. No doubt he had dictated them
+that afternoon and expected to sign them later. A glance told Cole
+that they pertained to political matters and dealt in detail with the
+availability of a certain candidate for alderman.</p>
+
+<p>He put the letters down. They confirmed a theory that he had formed
+that afternoon that the Bureau of Civic Research was a hobby of
+Englebreth’s. Like many another rich man, his former client presumably
+felt the need of justifying his existence in some way. Cole felt
+satisfied on that point, but there were other doubts in his mind.
+It was just possible that the rooms of the bureau were being used
+clandestinely by persons who were in the habit of sneaking in there
+at night. Being close <span class="pagenum" id="Page_211">211</span>to the fire escape they were within easy
+reach of the headquarters of The Unknown Seven. The guess was rather
+far-fetched, but it seemed to explain several things.</p>
+
+<p>Knowing that Carlin was waiting for him on the roof, and seeing that
+his quest was unavailing, Cole put out his flash and moved toward the
+door. He had advanced only a few steps when something prompted him to
+halt. A vague impression that some one had stopped outside the door
+came to him. He tiptoed to a corner of the room and waited. Presently
+he heard a key grate in the lock, and then the door came open. It was
+beginning to look as though his suspicions had been correct, that
+persons other than the regular tenants were visiting the offices at
+night.</p>
+
+<p>A light appeared in the outer room. Next he heard some one move across
+the floor. From his position, in the corner of the inner office, Cole
+could not see who the newcomer was, and he did not care to make his own
+presence known just yet.</p>
+
+<p>The footsteps were coming toward him, and Cole pressed close to the
+corner, as a figure appeared in the doorway. The footfalls gave him a
+queer sensation. He thought he recognized the plopping little sounds,
+suggestive of a walker who, instead of putting most of his weight on
+his heels, places his entire foot on the ground at once.</p>
+
+<p>While still within the doorway the newcomer reached out a hand and
+touched a switch on the inner wall. In the light that suddenly
+appeared, Cole saw that he had identified the footfalls accurately. The
+man was Professor Carmody, and <span class="pagenum" id="Page_212">212</span>Cole’s eyes narrowed as he recognized
+him. The scientist wore a faded silk hat and a long overcoat, just
+as Cole had seen him when he walked into Doctor Latham’s house the
+day before, and under his arm he carried a large umbrella. He walked
+straight to the middle of the office before he saw Cole, and then he
+stopped so abruptly that it seemed as if his gaunt form would topple
+over.</p>
+
+<p>“Hello,” he said, staring out of his small, mouse-colored eyes. His
+long nose, much too large for symmetry, was turned up, and his parted
+lips showed two rows of yellow teeth. He was plainly embarrassed, and
+to conceal the fact he grinned ostentatiously.</p>
+
+<p>“Good evening, professor,” said Cole, stepping forward. Though this was
+their first meeting at close quarters, he had reason to believe that
+Carmody knew who he was. Miss Brownell, he recalled, had told him that
+the professor was well aware that Cole had been watching him from a
+distance for some time.</p>
+
+<p>“Are you connected with the Bureau of Civic Research, professor?” Cole
+went on.</p>
+
+<p>“In a way, yes,” said Carmody. He had a very thin voice that had a
+habit of rising to a shrill pitch, or falling to a faint murmur,
+without regard to what he was saying. He peered at Cole in an
+apologetic way. “I don’t believe I’ve had the pleasure of meeting you
+before.”</p>
+
+<p>“Don’t you know who I am?”</p>
+
+<p>Carmody wagged his head. “I can’t say that I do.”</p>
+
+<p>“Too bad, professor. I was in hopes that you <span class="pagenum" id="Page_213">213</span>would remember me. One
+doesn’t like to ask favors of strangers.”</p>
+
+<p>“Favors?” Carmody’s face took on a forbidding frown. “You wish to ask a
+favor of me?”</p>
+
+<p>“Just a slight one. There is a book in your library that is very hard
+to obtain, and I am very anxious to read it. The author is one James
+Price.”</p>
+
+<p>The professor looked at him hard and long. “You are mistaken,” he said
+finally in a very low tone. “The author whom you mention is not in my
+collection. May I ask what led you to think that I own the book in
+question?”</p>
+
+<p>“A little bird told me.”</p>
+
+<p>“You take your information from curious sources.”</p>
+
+<p>“One has to, sometimes. By the way, professor, aren’t you keeping
+rather queer office hours? It is, let me see, a quarter past one.”</p>
+
+<p>“I might ask the same question of yourself.”</p>
+
+<p>“That’s so; you might.”</p>
+
+<p>“I might also ask what you are doing here. It is my impression that you
+do not belong on the premises.”</p>
+
+<p>“Hope I am not in the way. Please go ahead and attend to whatever
+business brought you here.”</p>
+
+<p>But Carmody seemed in no hurry. Cole could not know whether it was
+because he had abundant leisure on his hands, or because he did not
+care to attend to his business in another man’s presence, but it was
+evident that the professor was not disposed to gratify his curiosity.
+Now and then his mousey little eyes moved furtively about the room,
+<span class="pagenum" id="Page_214">214</span>and once they rested in a designing way on one of the flat-top desks.
+Cole, following his glance, was vaguely puzzled.</p>
+
+<p>“Pardon me, but aren’t you trespassing?” inquired Carmody after a pause.</p>
+
+<p>Cole folded his arms and smiled genially. “You are not going to order
+me out, I hope?”</p>
+
+<p>“Suppose I should do that?”</p>
+
+<p>“I would overlook your rudeness and refuse to take the hint. If you
+insisted, I might invite you to try to put me out. If you should make
+such an attempt and fail at it, I would suggest calling the police to
+your assistance. But I don’t think you will go that far, professor. You
+might be called upon to explain your own presence here, and that would
+prove embarrassing.”</p>
+
+<p>There was a calculating gleam in Carmody’s eyes. Cole, with a picture
+in his mind of Carlin waiting for him impatiently on the roof, was
+anxious to bring the interview to a climax. He had no intention of
+leaving until he had learned the object of the professor’s visit.</p>
+
+<p>Once more Carmody looked stealthily about the room, and again his
+glance rested on the desk. Cole’s lids narrowed, as he perceived that
+the desk, which seemed to be the object of the professor’s interest,
+was the one on which lay Englebreth’s unfinished letters. There
+were three other desks in the room, so it seemed odd that Carmody
+should center his attention on this particular one. Cole had already
+discovered that the drawers were empty, and that the desk contained
+nothing except the papers lying on top. Strange though it seemed, it
+<span class="pagenum" id="Page_215">215</span>looked as though the scientist’s visit to the office at this late hour
+was in some way concerned with the letters Englebreth had dictated that
+afternoon.</p>
+
+<p>The theory seemed rather far-fetched, so Cole decided to test it. He
+moved leisurely about the room a few times, then stopped before the
+desk at which the professor’s sly glances had been directed. In a
+casual manner he picked up the letters, looked hastily at two or three,
+then folded them across the middle and stuck them into his pocket.</p>
+
+<p>He knew, even before the letters reached his pocket, that his suspicion
+had been well founded. Carmody had watched his every move with growing
+excitement. His expression had changed from bewilderment to dismay, and
+finally his face took on a look of sullen determination.</p>
+
+<p>“What are you doing with those letters?” he demanded.</p>
+
+<p>“Taking them home,” said Cole easily, at the same time moving toward
+the door.</p>
+
+<p>“Wait!” said the professor sternly.</p>
+
+<p>Cole turned around and watched him with amusement. “What’s the matter?”
+he asked innocently. “What are these letters to you?”</p>
+
+<p>“You shall not leave this office with them. Give them to me at once.”</p>
+
+<p>He reached out a hand, and Cole saw that it trembled. Evidently he
+was desperately intent upon obtaining possession of the letters. Cole
+was at a loss to understand, for he knew that the epistles dealt with
+political affairs that could be of no vital concern to a man like the
+professor.</p>
+
+<p>“Don’t excite yourself,” he said quietly. “There’s <span class="pagenum" id="Page_216">216</span>nothing in these
+letters that would interest you. They contain nothing but dry political
+rot. What do you care about that sort of thing?”</p>
+
+<p>“Are you going to surrender them?” demanded Carmody, and the words
+sounded like an ultimatum.</p>
+
+<p>“I’ll promise to consider it if you will tell me why you want them.”</p>
+
+<p>The professor regarded him queerly. A look of bewilderment crossed his
+sullenly determined face. His crafty little eyes seemed to be trying to
+read Cole’s hidden thoughts. “Why pretend you don’t know?” he asked;
+then, in wheedling tones: “Come now! The joke has gone far enough. I
+know you are only trying to tease an old man. The letters, please.”</p>
+
+<p>Cole shook his head. Carmody’s very insistence upon obtaining the
+letters was reason enough why Cole should not give them up. Once more
+he started for the door, but a sharp “Wait!” interrupted his progress.</p>
+
+<p>Cole turned slowly and looked into the barrel of a pistol in Carmody’s
+hand.</p>
+
+<p>“My dear friend,” said the professor in his softest, lowest tones,
+“please do not force me to take drastic measures. It would grieve me
+exceedingly to have to deal harshly with you. The letters, please!”</p>
+
+<hr class="chap x-ebookmaker-drop">

+<div class="subheadc">THE LIGHT IN THE WINDOW</div>
+</div>
+
+<p class="drop-cap">COLE’S only response to Professor Carmody’s soft-spoken ultimatum was a
+smile. He knew that the scientist was the kind of foe who is the most
+dangerous when he uses his gentlest tones. It struck him as droll that
+he was risking his life for the sake of a few letters which, as far as
+he could see, he could put to no earthly use. He would not know what
+to do with them even if he should be able to depart with them safely.
+It was only Carmody’s earnestness in the matter that convinced him the
+letters must have a hidden significance.</p>
+
+<p>“Well, professor,” he said easily, “it looks like a deadlock. I don’t
+want to give up the letters, and you seem in no hurry to shoot.”</p>
+
+<p>The professor smiled still more blandly and took a tighter grip on the
+pistol. Cole believed he would shoot rather than see him depart with
+the letters. There was a certain grimness about the gaunt form and the
+sallow face which warned him that Carmody was playing a desperate game
+for high stakes. As often happens in tense moments, his mind turned to
+trivial things. He pictured Carlin waiting peevishly on the roof. He
+imagined Ballinger in the midst of another humorous yarn. A ludicrous
+vision of the hunchback, chained to the operating table in Doctor
+Latham’s house, flitted through his mind.</p>
+
+<p>But the pistol in Carmody’s hand baffled him. He <span class="pagenum" id="Page_218">218</span>felt no fear, but
+neither did he care to throw his life away needlessly. Once before in
+the past forty-eight hours he had looked into the muzzle of a pistol,
+but that one had been in Doctor Latham’s hand. He had laughed then
+and dared the physician to shoot, knowing that Latham, whatever other
+villainies he might be guilty of, was not the type that can shoot down
+a defenseless man in cold blood. He was too proud and high-spirited for
+that. With Carmody it was different. The professor was made of coarser
+stuff. He was not hampered by considerations of chivalry and fair play.
+He would shoot as soon as Cole’s back was turned.</p>
+
+<p>And so he restrained the impulse to laugh in the professor’s face and
+walk away. He preferred to bide his chance and watch for a sign of
+wavering in the hand that held the pistol. Growing tired of waiting, he
+decided to try a little stratagem that he had found successful in the
+past. It was a simple trick and based on one of the many queer antics
+of the human mind.</p>
+
+<p>He looked away from the pistol and began to gaze fixedly at a point on
+the opposite wall. Moments passed and grew into minutes, and still he
+stared rigidly, not a muscle in his face moving. His eyes were slanting
+upward, at a level of about a foot and a half above the professor’s
+head. The latter could not see what he was looking at, for he dared
+not turn his head, knowing that Cole would jump the moment he did
+so. At first he was mildly puzzled. Then his face showed signs of
+bewilderment. His curiosity changed into nervous concern.</p>
+
+<p>By and by he seemed plainly worried. It was <span class="pagenum" id="Page_219">219</span>evident that Cole’s fixed
+and silent scrutiny of something which the professor could not see was
+seriously affecting his nerves.</p>
+
+<p>Cole’s rapt expression did not change in the slightest degree. He just
+looked and looked at that blank point somewhere behind the professor’s
+back and just above his head. Carmody grew more and more disconcerted.
+A tension, which he was doing his best to check, was taking hold of
+him. He shifted from one foot to the other. A sense of something weird
+and unaccountable was stealing over him, despite his scientific poise
+of mind.</p>
+
+<p>At last came the chance for which Cole had waited. It was merely an
+uneasy flicker in Carmody’s eyes, accompanied by a slight turn of
+the head. It was not much, but Cole knew that, for the moment, the
+professor’s mind was diverted from the pistol. It was risky, but he
+might not get another chance. He flexed his muscles, and leaped, first
+to one side, then straight at Carmody, wrenching the pistol from his
+hand.</p>
+
+<p>A squeallike cry broke from the professor’s lips. Cole chuckled as he
+ran. The scientist started in pursuit, but Cole slammed the door in
+his face. In another instant, putting the pistol in his pocket, he was
+climbing through the window. Soon he was hurrying up the fire escape. A
+dark figure, with coat tails flapping in the wind, hastened toward him,
+as he swung over the parapet and landed on the roof.</p>
+
+<p>“Where on earth have you been?” asked Carlin reproachfully. “I was just
+on the point of going down to look for you.”</p>
+
+<p><span class="pagenum" id="Page_220">220</span></p>
+
+<p>“Is there a man on the staff who understands ciphers?” inquired Cole,
+taking the lawyer’s arm and hurrying him down from the roof.</p>
+
+<p>“Ciphers? Why, yes. Findlay Abbott is one of the best cipher experts in
+the country. What do you want of him?”</p>
+
+<p>“Find him and send him to my office,” said Cole hurriedly. Leaving the
+bewildered lawyer several paces behind, he ran down the corridor and
+entered his office. He had been there only a few moments when Abbott, a
+fat and pink-faced little man, trundled in. Behind him walked Carlin.
+Cole took the letters from his pocket and handed them to the expert.</p>
+
+<p>“See if you can make anything out of these, Abbott,” he directed. “All
+I know about them is that they are so important to one man that he was
+ready to shoot me on account of them. They may be in code.”</p>
+
+<p>Abbott looked as though he relished the task. He sat down, wiped his
+spectacles, and fell to work. In the meantime Cole told the lawyer of
+the episode in room 2512.</p>
+
+<p>Carlin’s eyes popped as he listened. He glanced with keen interest
+at the papers under Abbott’s nose. “You don’t think the offices of
+the Bureau of Civic Research are the headquarters of the gang we are
+fighting?”</p>
+
+<p>“No,” said Cole thoughtfully. “In the morning you might inquire of
+your agent how long the bureau has been located there. From what I
+saw, though, it looked as though the concern was on the square. It’s
+more likely that certain parties are <span class="pagenum" id="Page_221">221</span>using the offices as a listening
+post, because of their close proximity to this establishment. Knowing
+that we are fighting them, those fellows naturally want to find out how
+much we know and what our plans are. I have a strong suspicion that the
+dictaphone wires ran into the rooms below. What do you make of those
+letters, Abbott?”</p>
+
+<p>But Abbott was too deeply engrossed in his task to hear the question.
+The other two watched him in silence for a time. His puckered brow told
+that the letters presented a knotty problem. Finally he looked up.</p>
+
+<p>“No code here,” he declared. “These are just ordinary letters.”</p>
+
+<p>“Sure of that?” demanded Cole sharply.</p>
+
+<p>“As sure as one can be of anything. I’ll wager my salary for the next
+ten years that these are just plain letters.”</p>
+
+<p>“Then why did Carmody——” Cole suddenly gave the desk a resounding
+thwack. A light of comprehension dawned in his eyes. “I take my hat
+off to the professor. He is a slick little trickster. He wanted to get
+me away from there, having private business to attend to, and so he
+pulled the wool over my eyes and made me think that these letters were
+a matter of life or death. Carlin, I’m a boob!”</p>
+
+<p>He bounded from the office, leaving the lawyer and Abbott to stare
+at each other. He was angry, but only with himself. For the crafty
+professor he felt an unwilling admiration, but he was also determined
+not to let Carmody have the last laugh.</p>
+
+<p>The discovery that Englebreth’s letters were genuine had given him a
+sharp mental jolt. A suspicion <span class="pagenum" id="Page_222">222</span>had been gradually assuming shape and
+clarity in his mind, but the cipher expert’s report had uprooted it
+completely. All that those letters now meant to Cole was a wasted hour
+and a sense of humiliation.</p>
+
+<p>He hurried up to the roof, then down the fire escape, and soon he
+stood once more outside the door of room 2512. Carmody had had ample
+time to dispose of whatever business had brought him there, but it was
+just possible that he had not yet left, so Cole entered as quietly as
+he could. The moment he closed the door behind him he knew he was too
+late. The light that appeared at his touch on the button revealed two
+empty rooms.</p>
+
+<p>Cole moved forward, looking sharply over walls and behind furniture.
+Perhaps Carmody had accidentally left some clew to his mysterious
+errand. It was even possible that Cole might get an inkling as to the
+discovery that had cost McKendrick his life. He searched carefully, but
+at first with no results. There were fresh, but very faint, footprints
+on the floor, and he could easily locate the spot where he and Carmody
+had stood, while the professor was pointing the pistol at him. Which
+way had Carmody turned after Cole left the offices? The footprints
+reached to the door and then back into the inner office. Evidently
+Carmody had locked himself in before attending to his errand. With some
+difficulty Cole traced the faint marks across the floor, muttering a
+short exclamation when he found that they led straight to the safe,
+standing in a corner of the room.</p>
+
+<p>Cole had given the safe only a cursory glance on his previous visit
+to the office. Carmody’s entrance <span class="pagenum" id="Page_223">223</span>had prevented him from making a
+more careful examination. Now he saw that the safe was one of the best
+and latest makes. There was a look of freshness about the blue steel
+surface and the bright nickel trimmings which suggested it had not
+been there long. He remembered that this particular brand of safe, in
+addition to its other advertised merits, was supposed to be air-tight
+and absolutely burglar proof. It seemed rather large for a concern
+whose affairs were transacted in two small rooms, but, perhaps, it had
+been selected with a view to growing needs.</p>
+
+<p>The course of the footprints made it plain that Carmody’s errand had
+been related to the safe in some way, but that was as far as Cole’s
+deductions reached. Whether the professor had removed something from
+the steel box, or put something in, he had no means of knowing, and the
+locked door prevented him from gratifying his curiosity on that point.
+It did not stop him from exercising his imagination, however. With a
+grim nod and a tightening of the lips he made a guess in regard to
+Carmody’s business with the safe.</p>
+
+<p>There was nothing more he could do for the present, so he made his
+way back to the headquarters of The Unknown Seven. In the hall he met
+Carlin.</p>
+
+<p>“Well?” asked the lawyer. “Found out anything?”</p>
+
+<p>“The more I find out about this case the less I know,” confessed Cole.
+“All the same, I think I know what it was McKendrick saw that cost him
+his life.”</p>
+
+<p><span class="pagenum" id="Page_224">224</span></p>
+
+<p>Carlin’s brows came up.</p>
+
+<p>“But I’m not going to tell you what it was,” Cole added quickly. “I may
+be mistaken, you see, and I don’t propose to jeopardize my reputation
+with you. By the way, there’s a new safe in number 2512, as nifty an
+article of that kind as I ever saw. Pretty good size, too. Big enough
+for a man of your dimensions to sit down in, Carlin.”</p>
+
+<p>“You’re not going to ask me to crawl into it, I hope?”</p>
+
+<p>“No, nothing like that. I just have a hunch that in the morning that
+safe is going to be taken out of 2512.”</p>
+
+<p>“Anything unusual in that?”</p>
+
+<p>“Nothing at all, and that’s just what certain parties are counting
+on, I think. There are times when it is expedient to do the unusual
+thing under cover of the usual. I want you to detail a man to see what
+happens to that safe, Carlin.”</p>
+
+<p>The lawyer nodded, but in the next instant his eyes opened wide in
+astonishment. “You don’t think that——”</p>
+
+<p>“As I said before,” Cole interrupted, “I don’t care to risk my
+reputation on a guess that may prove unfounded. Seen anything of
+Ballinger lately?”</p>
+
+<p>“Not for half an hour or so. Been busy in the main office.”</p>
+
+<p>Cole gave him a keen glance. “What’s the matter, Carlin? You look
+worried.”</p>
+
+<p>The lawyer forced a smile. “It’s just a—a premonition. I guess that’s
+what you would call it. I have a feeling that the gang knows we are
+closing in around them, and that they are getting ready <span class="pagenum" id="Page_225">225</span>to cash in. We
+must strike quickly, or it will be too late.”</p>
+
+<p>“I don’t know but what you are right. I’ve felt something of the same
+kind myself. We must not only strike quickly, but with both fists.” As
+if he had meant it literally, Cole looked down at his clenched hands.</p>
+
+<p>“But where, Cole? Where are we going to strike? We don’t know who the
+leader of the gang is. That is, we can’t be sure. We don’t know where
+the plant is located. We don’t even know——”</p>
+
+<p>“You make me dizzy,” said Cole with a chuckle, and then he turned
+abruptly and walked into his private office. There he pressed a button,
+and in a few moments Sambo entered.</p>
+
+<p>“Ask Miss Brownell to step in here,” Cole told the big negro.</p>
+
+<p>Sambo’s eyes opened wide, showing a generous expanse of white. “Why,
+she done lef’ a hour ago, sah. She went out in a mighty rush, too.”</p>
+
+<p>“Sure of that, Sambo?”</p>
+
+<p>“Course I’s sure. I seed her mahself. It was just after Doc Ballinger
+lef’, sah.”</p>
+
+<p>“Doctor Ballinger?”</p>
+
+<p>“Yes, sah. The doc looked lahk he was wurried. The wurriedest man I
+eveh seed, sah. He tried not to let on, but he didn’t fool mah a-tall,
+sah.”</p>
+
+<p>“And you say Miss Brownell left shortly afterward?”</p>
+
+<p>“Yes, sah. Not more’n a minute, sah.”</p>
+
+<p>Cole jumped up from his chair. For a moment he stared at the gigantic
+negro, then waved a hand in dismissal. He had instructed Miss Brownell
+to <span class="pagenum" id="Page_226">226</span>put one of the men on Ballinger’s trail, in case the physician
+should go out. Now it seemed evident that the girl herself had started
+out to shadow the doctor. Cole could only hope that her audacity would
+not lead her into trouble. His acquaintance with women had been only
+casual, and he had an impression that they either fainted in a crisis,
+or else burst into tears. Miss Brownell was, of course, a variant from
+the usual type, but just the same——</p>
+
+<p>Cole sat down again. After all, he could do nothing for the present,
+and Miss Brownell seemed to have a surprising capacity for taking care
+of herself. He would stay close to the telephone, and, in due time,
+she would undoubtedly call him up. He waited, but the instrument at
+his side remained tantalisingly silent. When at length it shrilled a
+summons, he jumped nervously.</p>
+
+<p>But the person calling was not Miss Brownell. Instead, it was Sloane,
+the operative whom Cole had detailed to watch Doctor Latham’s
+residence. Latham and the hunchback had been far from his mind for
+several hours.</p>
+
+<p>“What is it, Sloane?” he asked quietly.</p>
+
+<p>Sloane reported that for the last hour a mysterious light had appeared
+at intervals in one of the windows of the doctor’s house. It might mean
+anything or nothing, and Sloane did not know what to make of it, so he
+was telephoning in for instructions.</p>
+
+<p>“Stay where you are,” Cole told him. “I’ll be with you in a little
+while.”</p>
+
+<p>For a few moments longer he sat at the desk, his mind working quickly.
+It was just possible that <span class="pagenum" id="Page_227">227</span>at Latham’s house he would find some clew to
+the movements of Ballinger and Miss Brownell. There was a fog in his
+mind, the result of too many conflicting developments, but there were a
+few things that seemed clear.</p>
+
+<p>Soon he was out on the street. In less than half an hour he reached
+the corner nearest Latham’s house and walked east on the opposite side
+of the street. He cast sharp glances into the shadows along the row of
+buildings. Suddenly he stopped. “Sloane,” he said in a low tone.</p>
+
+<p>The scholarly looking operative stepped out of a gloomy doorway. “Glad
+you came, sir,” he whispered. “Things look queer.”</p>
+
+<p>“What about the light you mentioned?”</p>
+
+<p>“It comes and goes, every two minutes or so. Look! There it is!”</p>
+
+<p>He pointed to a window on the second floor of the physician’s
+residence. A small, flickering light had just appeared. It wavered
+for a few moments, then faded out. The two men waited in silence, and
+presently the mysterious light came back. All the other windows were
+dark, and the solitary glow had an eerie look.</p>
+
+<p>“Stay here,” said Cole. “Don’t move unless I signal you by whistling
+three times from one of the windows.”</p>
+
+<p>Briskly he crossed the street. A bunch of skeleton keys rattled in his
+hand, as he vanished from sight in the dark basement entrance.</p>
+

+<div class="subheadc">A WARNING</div>
+</div>
+
+<p class="drop-cap">VERY softly Cole crept up the stairs. On the ground floor he stopped
+for a moment and listened. A heavy silence seemed to hover over the
+entire house. He stole up another flight of stairs and turned toward a
+door in front. The knob turned noiselessly in his hand, but the door
+was locked. He stooped and tried to peep through the keyhole, but he
+could see nothing.</p>
+
+<p>A few moments passed; then a slight scratching sound, like that
+produced when a match is struck, was heard within. At the same time a
+faint glow was visible through the keyhole. It lasted for ten seconds
+or so, and then all was darkness again. It was evident now that the
+intermittent glow which Cole had seen from the sidewalk had been
+produced by some one striking a number of matches.</p>
+
+<p>Suddenly he stood erect, listening. For a moment he thought he had
+heard a slight sound, coming from somewhere below, but apparently he
+had been mistaken. He had entered so quietly that it did not seem
+possible Doctor Latham’s sleep could have been disturbed by his
+movements. Again he fixed his attention on the door, for once more
+a scrrrrch came from the room. Through the keyhole, just before the
+fluttering light went out, he caught a glimpse of the hunchback.</p>
+
+<p>Cole was puzzled. What could the hunchback <span class="pagenum" id="Page_229">229</span>be doing, and what did
+the frequent striking of matches mean? He waited, uncertain what to
+do, but strongly tempted to open the door with one of his skeleton
+keys. Moments passed, and he listened in vain for further repetitions
+of the scratching sounds. Instead, he heard what sounded like a
+half-suppressed chuckle. Evidently the hunchback had found something
+that pleased him. A faint tinkle came through the keyhole, followed by
+a louder sound, like that of a heavy object being dragged across the
+floor. Then silence.</p>
+
+<p>Cole felt in his pockets for his bunch of keys, but he quickly withdrew
+his hand and cast a glance over his shoulders. This time he knew he
+was not mistaken. Some one was moving about on the floor below, but
+so softly that Cole’s keen ears detected only a faint suspicion of a
+sound. His eyes darted to left and right in search of a hiding place,
+but the best he could find was the corner back of the stairway railing.
+He pressed against the wall and crouched low.</p>
+
+<p>Some one was coming up the stairs. He was determined to learn as much
+as he could before he made his presence known. The meager light from
+the little electric bulb in the ceiling revealed a sweep of bald
+cranium, by which he easily identified Doctor Latham. Perhaps he had
+been awakened by the hunchback’s movements, or perhaps Cole’s entrance
+had partly aroused him, and he had just now become fully awake.</p>
+
+<p>The doctor swept past him without a glance in his direction and moved
+straight toward the room occupied by the hunchback. There he stopped,
+took <span class="pagenum" id="Page_230">230</span>a key from his pocket and unlocked the door. He pushed it open
+and stood in a listening attitude. Even from his remote position in the
+rear of the hall, he could hear a lusty snoring. It was strange, since
+he knew that the hunchback had been wide awake only a few minutes ago.
+Evidently the fellow was up to a ruse of some kind.</p>
+
+<p>Suddenly Latham turned and walked quickly toward the rear. For a moment
+Cole thought he had been discovered, but the doctor took only half a
+dozen steps down the hall. Standing on the stairway railing he removed
+the electric bulb from its socket in the ceiling, then entered the
+hunchback’s room. The hall was now dark, and Cole thought it safe to
+come forward. He reached the door just as a light appeared within.
+Peeping through the crack between the door and the jamb he saw that the
+physician had attached the bulb to a wall fixture. Now he was standing
+beside the operating table to which the hunchback had been linked for
+the past twenty-four hours, leaning over the motionless figure lying on
+it.</p>
+
+<p>He mumbled something beneath his breath, then gave the hunchback’s
+shoulder a vigorous shaking. The snoring stopped. The fellow sat up
+with difficulty and rubbed his eyes with his free hand.</p>
+
+<p>“You needn’t pretend,” said Latham. He was arrayed in the same dressing
+gown in which Cole had seen him once before. “I know you haven’t been
+sleeping. Where did you find these matches?”</p>
+
+<p>He pointed to a litter of charred stubs on the floor. The hunchback
+eyed him stolidly and shrugged his misshapen shoulders.</p>
+
+<p><span class="pagenum" id="Page_231">231</span></p>
+
+<p>The doctor’s glance went to an old battered safe in a corner of the
+room. He stepped up to it and tried the lock.</p>
+
+<p>“Thought you might be tempted to while away the time by investigating
+this old safe of mine,” he declared. “I removed the bulb on purpose, so
+you wouldn’t make much headway with it. Not that you would have found
+much if you had opened it, only a few papers.”</p>
+
+<p>Again he gazed at the charred fragments scattered over the floor. Cole,
+looking through the narrow crack, saw a puzzled frown on his bearded
+face. The room was small, and the conglomeration of articles in it
+suggested it was used in part for storage purposes. The scattered match
+stubs perplexed Cole as much as they did the doctor.</p>
+
+<p>“There might have been a box in one of the bureau drawers,” muttered
+the physician. “I suppose that’s where you found them. I don’t see,
+though, what pleasure you derive from burning up a lot of matches.”</p>
+
+<p>Cole was watching the hunchback’s face. A look of sly satisfaction
+lurked in the sallow features. Once the fellow bent a squinting glance
+on some object across the floor, but all Cole could see at that
+particular point was a dilapidated trunk. His bewilderment grew. The
+scene between the physician and the hunchback was not exactly what he
+might have suspected. He sensed a hidden element in it. He was aware of
+a curious strain and tension in the air.</p>
+
+<p>“I thought I heard you drag the table over the <span class="pagenum" id="Page_232">232</span>floor,” remarked the
+doctor. “You were not doing it just for exercise. What was your idea?”</p>
+
+<p>Again a look of secret elation crossed the hunchback’s face. He jingled
+the steel links that held one of his hands to the table.</p>
+
+<p>“Aw, can’t a guy move about a bit if he wants to?” he asked. “Sittin’
+still in one place all the time gets on a feller’s nerve. I didn’t do
+no harm.”</p>
+
+<p>The physician regarded him searchingly. Evidently he, too, had seen
+the furtive smirk in the hunchback’s face. He stepped briskly to the
+operating cot and shook the fellow’s arm.</p>
+
+<p>“I’m not so sure about that,” he remarked. “You have been up to some
+kind of deviltry, my man. Now——”</p>
+
+<p>The sentence ended in a gasp. In a twinkling the hunchback had wrenched
+his arm free of the doctor’s grasp. Cole was amazed at the swift play
+of his fingers. He could scarcely see what was happening, but a loop
+fell down over the physician’s head and was tightened around his throat
+with a quick jerk. He spluttered and choked, while the hunchback
+snickered gleefully.</p>
+
+<p>“I got yuh now!” declared the little man, drawing the loop still
+tighter. The doctor wriggled and squirmed, but the constriction at his
+throat weakened his efforts. The whole scene seemed unreal to Cole.
+It took him several moments to realize that Latham was being garroted
+by the man who had found refuge in his house after murdering Malcolm
+Reeves.</p>
+
+<p>He bounded forward, and a well-aimed blow sent the hunchback reeling
+back over the operating <span class="pagenum" id="Page_233">233</span>table. The garrote, made up of two shoe laces
+tied together, had bitten deep into the flesh around the doctor’s
+throat. His eyes bulged, and his gaping lips were bloodless. A hoarse
+rattle sounded in his throat, as he struggled for breath.</p>
+
+<p>In a short time the noose was undone, and the physician sank into a
+chair. While he sucked air into his lungs in great gulps he looked
+queerly at Cole. The hunchback lay sullenly silent on the table.</p>
+
+<p>“Your visit was very opportune this time,” murmured Latham, as soon as
+he began to breathe more easily. “Where did you come from?”</p>
+
+<p>Cole signified with a shrug that the matter was of no importance.
+“What’s gotten into this protégé of yours?” he asked with a glance at
+the hunchback. “Did he go crazy all of a sudden?”</p>
+
+<p>“Oh, no; he’s as sane this moment as he ever was or ever will be. I
+knew he would kill me if he got a chance, and so I did all I could to
+deprive him of the opportunity.”</p>
+
+<p>There was doubt and bewilderment in Cole’s gaze. “But why should he
+kill you? I thought——”</p>
+
+<p>“Yes, I think I know what you thought,” interrupted the doctor. “For
+a man of keen intellect you have a singular capacity for getting
+things twisted. I suppose, however, it isn’t to be wondered at under
+the circumstances. Wonder where the fellow got those shoe laces. I
+thought I had removed from his reach everything that might serve as an
+implement of murder.”</p>
+
+<p>Cole stepped to the trunk at which the hunchback had been squinting
+from time to time. He <span class="pagenum" id="Page_234">234</span>lifted the lid, and the first thing he saw was a
+pair of old shoes from which the laces had been removed.</p>
+
+<p>Latham looked at him in surprise. “That trunk was locked this morning,”
+he remarked.</p>
+
+<p>“The lock is a very simple one,” Cole observed. “Even a man with only
+one arm could pick it without much trouble. With a supply of matches
+handy, the removal of the electric bulb didn’t give him much of a
+handicap. You seem to lead a very exciting life, doctor.”</p>
+
+<p>The doctor smiled. He felt quite at ease again. He got up from the
+chair and strolled over to the table where the hunchback lay.</p>
+
+<p>“You are really very simple,” he declared. “Didn’t you know that
+murdering me wouldn’t help you out of your predicament? Why, you would
+have starved to death if you had carried out your attempt.”</p>
+
+<p>“Guess again.” The fellow leered insolently. “My pals woulda found me
+before long. To-night, maybe.”</p>
+
+<p>“What’s your grudge against the doctor?” inquired Cole. “Why did you
+try to kill him?”</p>
+
+<p>“Why don’t you ask him?” retorted the hunchback, wagging his head in
+the physician’s direction.</p>
+
+<p>“Our friend doesn’t seem very communicative,” observed Latham. “I don’t
+think he will attempt any more mischief to-night. Suppose we go down
+and sample one of my cigars?”</p>
+
+<p>Cole assented, but not until he had searched the hunchback and removed
+a handful of matches. He believed the doctor knew the motive behind the
+murderous attempt. There was a fog in his mind, for <span class="pagenum" id="Page_235">235</span>the scene he had
+just witnessed did not seem to harmonize with his previous observations.</p>
+
+<p>“You are a cool one, doctor,” he remarked when they were down in the
+consultation room and the physician had passed his box of cigars.</p>
+
+<p>“Life hardens one. I sometimes wish I hadn’t lost my emotional
+susceptibilities. They are the things that give color and tone to life.
+Life without thrills is a barren desert.”</p>
+
+<p>Cole suddenly recalled his original errand. He bent forward and looked
+the doctor full in the eyes. “There is one question I want to ask. You
+may not be able or willing to answer it. Where is Miss Brownell?”</p>
+
+<p>The question acted like an electric shock on the physician, upsetting
+his magnificent composure as nothing else could have done. A suspicion
+of pallor crept up beneath the black beard.</p>
+
+<p>“What about her?” he demanded sharply. “Has anything happened to her?”</p>
+
+<p>Cole smiled amusedly. “For a man who has lost his emotional
+susceptibilities you manage to work up quite a lot of feeling over a
+simple question. You know the lady I am referring to?”</p>
+
+<p>“Why—er—slightly.”</p>
+
+<p>Cole gave him a hard, searching glance. He felt the doctor had
+deliberately understated the truth. “Miss Brownell disappeared this
+evening,” he announced. “I came here in the hope of learning something
+of her whereabouts from you.”</p>
+
+<p>“Why from me?” Latham was laboring under a tension that he tried hard
+to suppress.</p>
+
+<p>“Several trails seem to point in your direction, <span class="pagenum" id="Page_236">236</span>doctor. Do you know
+what has become of Miss Brownell?”</p>
+
+<p>Latham gripped the arms of his chair. “I swear I haven’t the faintest
+idea,” he declared, looking Cole straight in the eyes.</p>
+
+<p>Cole believed him. There was something in the doctor’s tone and
+manner that carried conviction. He knew that for once the man was
+not shamming. His gaze cut deep into the physician’s bewildering
+personality, and he found not a trace of duplicity.</p>
+
+<p>“What is Miss Brownell to you?” he asked bluntly. “Not in love with
+her, are you, doctor?”</p>
+
+<p>The bearded lips parted in a faint smile. “I admire her immensely.
+Have known her for a long time. Was a friend of her father’s. A very
+charming young person indeed. But at my age one hesitates before he
+permits himself to fall in love. Besides, Miss Brownell is not likely
+to entertain any romantic notions in regard to me.”</p>
+
+<p>Cole nodded thoughtfully. Despite the doctor’s light tone and airy
+gestures, the real Dickson Latham stood revealed before him.</p>
+
+<p>“I understand, doctor,” he said meaningly. “I see how it is with you.
+As for Miss Brownell, she left a certain place, about an hour and a
+half ago, in pursuit of a colleague of yours, Doctor Ballinger.”</p>
+
+<p>A queer little mutter slipped from Latham’s lips. He clenched his hands
+convulsively; his face underwent a startling transformation; a mingling
+of hate and fear showed in his dark, flashing eyes.</p>
+
+<p>“That hound!” he mumbled under his breath, evidently not intending Cole
+to hear. With an inward <span class="pagenum" id="Page_237">237</span>wrench he steadied himself; in the next moment
+he seemed cool and composed. “In that case we must endeavor to find
+her,” he added aloud.</p>
+
+<p>“More easily said than done, doctor. Have you any idea where Ballinger
+might have taken her; in the event that she should have fallen into his
+hands?”</p>
+
+<p>“There is one place he would naturally take her to, but I don’t know
+the geographical location of it.”</p>
+
+<p>“In plain words, the headquarters of a certain gang of alchemists and
+cutthroats?”</p>
+
+<p>Latham nodded.</p>
+
+<p>“You are mixed up with this gang, aren’t you, doctor?”</p>
+
+<p>“I was.”</p>
+
+<p>“And you performed an operation on Malcolm Reeves?” Cole watched him
+closely to observe the effect of his question.</p>
+
+<p>“That is true,” said Latham in a queer tone. He smiled a sad, whimsical
+smile. “But you must have observed that truth sometimes covers a
+multitude of lies.”</p>
+
+<p>Cole pondered this cryptical statement. “One more question. Why did the
+hunchback try to kill you?”</p>
+
+<p>“Some men are willing to do anything for money. But this line of talk
+isn’t leading us anywhere. The thing of prime importance is to find
+Miss Brownell. From what little I know of the gang, to which you
+referred, I should say her life isn’t worth a plugged nickel if she has
+fallen into their hands.”</p>
+
+<p>He spoke evenly, but Cole sensed an ache behind <span class="pagenum" id="Page_238">238</span>the words. “Do you
+know the leader of the organization?” was his next question.</p>
+
+<p>“He was never referred to by name in my presence, and I never came in
+contact with him. In my dealings with the members I never got higher
+than Professor Carmody.”</p>
+
+<p>Again, despite the contradictions and discrepancies that hemmed in the
+doctor’s statements, Cole was disposed to believe him. “There is no
+cause for alarm just at present,” he declared. “We don’t know that Miss
+Brownell is in trouble. She is a capable young woman and——”</p>
+
+<p>“Ah, but you don’t know Ballinger,” interrupted Latham.</p>
+
+<p>Cole reached for the telephone and called the number of The Unknown
+Seven. After a brief delay he was connected with Carlin.</p>
+
+<p>“Where are you?” demanded the lawyer excitedly. “Been trying to get
+hold of you everywhere.”</p>
+
+<p>“What has happened?” asked Cole evenly, though the lawyer’s agitation
+was contagious.</p>
+
+<p>“Happened!” echoed Carlin. “Received an anonymous telephone message a
+while ago warning us that, unless we keep hands off, Miss Brownell will
+be dead inside twenty-four hours!”</p>
+

+<div class="subheadc">THE VENEER OF INTELLIGENCE</div>
+</div>
+
+<p class="drop-cap">THE doctor’s face betrayed his anxiety, as Cole repeated what he had
+just heard over the telephone.</p>
+
+<p>“That settles it,” muttered the physician. “We must find Miss Brownell
+at once.”</p>
+
+<p>Cole nodded. For several minutes he had been watching the physician
+closely. It was as if a veil had been removed from one phase of
+Latham’s many-sided character. Cole looked through the contradictions
+of his personality, and he knew that on one point, at least, the doctor
+was sincere. That was in his attitude toward Miss Brownell.</p>
+
+<p>“There’s no hurry,” he said calmly. “Nothing is going to happen to her
+for twenty-four hours.”</p>
+
+<p>“But why delay?”</p>
+
+<p>“Because we can do nothing else. Another reason is that I need sleep.
+The third reason is Toots.”</p>
+
+<p>“Toots?” Latham frowned. “Who is Toots?”</p>
+
+<p>“The most distracted cat in the State of New York at the present
+moment. My rooms were invaded by prowlers this afternoon, everything
+thrown helter-skelter, and Toots just can’t bear fuss of any kind.
+She is a very temperamental cat, doctor. You will hear from me in the
+morning.”</p>
+
+<p>He left the scowling physician and walked toward the door. There he
+stopped and looked back. <span class="pagenum" id="Page_240">240</span>“Don’t worry,” he said. “We will see Miss
+Brownell out of this. There’s something of a plan buzzing around in my
+mind. So long, doctor.”</p>
+
+<p>Cole walked out. Despite his cheerful tone he was not altogether free
+from worry. The situation, as far as Miss Brownell was concerned,
+looked critical enough. With the fate of Reeves and McKendrick in mind,
+Cole knew the gang would not stop short of murder, if it suited their
+plans. The hope he had tried to instill in Doctor Latham was based on
+the advantages which he held over the other side. So far Ballinger
+did not know that he was being suspected, and this was an important
+point in Cole’s favor. A man who thinks himself safe is apt to make
+blunders and become incautious. Another advantage lay in the fact that
+the conspirators knew nothing of the deductions Cole had made from
+Carmody’s visit to the offices of the Bureau of Civic Research, or of
+his suspicions in regard to the big safe standing there.</p>
+
+<p>Cole went home, noticed with approval that Mrs. Armstrong had tidied
+up his rooms, and that Toots was sleeping tranquilly on her favorite
+cushion. In a few minutes Cole himself was sound asleep. Five hours he
+slept, and then he awoke clear-eyed and vigorous. After feeding Toots
+and getting his own breakfast, he went to the offices of The Unknown
+Seven. On his desk he found a note from Carlin announcing that the
+lawyer had, in accordance with Cole’s instructions, detailed one of the
+operatives to watch room 2512 and report at once if the safe should be
+taken out.</p>
+
+<p>Cole crumpled the note in his fist. It was yet <span class="pagenum" id="Page_241">241</span>early, and only a few
+members of the staff were on duty. He went to the end of the hall and
+glanced into the room where the body of McKendrick lay. What to do with
+it was a delicate problem in view of the fact that the operations of
+The Unknown Seven were being conducted secretly. Perhaps the best way,
+was Cole’s reflection, would be to encase it in a plain box and ship
+it anonymously to the morgue. Later, in some indirect way, he would
+endeavor to see that the hunchback was duly punished.</p>
+
+<p>He locked the door of the little room and went back to his office.
+He had been there only a few minutes when Doctor Ballinger, after a
+discreet knock, stepped in.</p>
+
+<p>“You are early, doctor,” remarked Cole genially.</p>
+
+<p>Ballinger sat down and crossed his long legs. “I’ve been looking for
+Miss Brownell,” he explained. “Seen anything of her?”</p>
+
+<p>“No,” said Cole casually, knowing that the doctor was watching him
+keenly. “A bit too early for her, I guess. No doubt she will be
+strolling in soon.”</p>
+
+<p>“Making any progress?”</p>
+
+<p>“Rome wasn’t built in one day,” said Cole evasively, knowing that the
+question was a subtle feeler. “I’m just taking hold of the job, you
+know.”</p>
+
+<p>“Still think there’s a traitor among us?”</p>
+
+<p>“I not only think it, but I am sure of it,” declared Cole testily, as
+if reproaching himself for his failure to expose the renegade. He was
+on the point of saying more, but just then the telephone <span class="pagenum" id="Page_242">242</span>rang. It was
+Fessenden, the operative who had been detailed to watch room 2512.</p>
+
+<p>“They’re just taking it out, sir,” reported Fessenden, cautiously
+hiding the gist of his statement behind the neutral pronoun.</p>
+
+<p>“Well, stay on the job and report developments to me,” said Cole in
+tones that seemed to indicate that the matter was of no particular
+importance. “You see,” he went on, turning to the doctor, as he hung up
+the receiver, “I spilled the beans at dinner. The traitor has had his
+warning, and from now on he will be a hard man to catch.”</p>
+
+<p>The doctor agreed with him. They discussed the matter from various
+angles and finally the telephone rang again. Fessenden reported that
+“it” had been loaded onto a truck.</p>
+
+<p>“Stay with it,” said Cole laconically. “Telephone me when you can.”
+He was aware of a questioning gleam in the doctor’s eyes, as he hung
+up, but he pretended to have noticed nothing. “Fessenden thinks he has
+come across a clew,” he added for Ballinger’s benefit. “Don’t think it
+amounts to anything, but it’s just as well to run it down.”</p>
+
+<p>“What sort of clew?”</p>
+
+<p>“It seems to have something to do with the murder of Reeves,” said Cole
+indifferently. “Not more than one clew out of twenty ever pans out, and
+I haven’t much hope for this one.”</p>
+
+<p>The doctor seemed to have been deceived by his tone. After a few more
+remarks he walked out. In spite of what he had told Carlin the night
+before, he had been far from certain that the safe would be taken out;
+at any rate he had not expected it <span class="pagenum" id="Page_243">243</span>would be done before another night.
+Fessenden’s report had started a long train of thoughts in his mind.</p>
+
+<p>Shortly before noon the lawyer walked in.</p>
+
+<p>“I’ve just made some inquiries about the Bureau of Civic Research,”
+he reported, after he had been told that there was no news of Miss
+Brownell. “There isn’t the slightest doubt about its genuineness.
+Some of the biggest men in town belong to it. It’s a sort of reform
+organization; interested in political uplift and that kind of thing.
+They’ve occupied the two offices down below ever since the building
+opened.”</p>
+
+<p>“That’s interesting,” said Cole, looking as if his trend of thought had
+taken a sharp quirk. “By the way, the safe was taken out of room 2512 a
+little while ago.”</p>
+
+<p>“Anything startling in that?”</p>
+
+<p>“Well, it’s just possible that, if we can follow the safe to its
+destination, we shall find Miss Brownell.”</p>
+
+<p>“How do you make that out? What has the safe to do with Miss Brownell?”</p>
+
+<p>“My reasoning is based on the assumption that certain parties are as
+anxious to hide the one as the other. If that is so then it is only
+natural to suppose that they will hide both in one place. That safe,
+Carlin, represents our only hope of getting Miss Brownell out of
+danger.”</p>
+
+<p>The lawyer scratched his head thoughtfully. “I would advise you to
+move cautiously. Those blackguards would kill her without the slightest
+hesitancy if——”</p>
+
+<p><span class="pagenum" id="Page_244">244</span></p>
+
+<p>“Oh, I’ll be careful,” promised Cole. “All the same we must move
+quickly. I think your hunch yesterday was right, Carlin. The gang is
+getting ready to cash in their chips. They are holding the threat of
+death over Miss Brownell in the hope of influencing us through her and
+making us let them alone till after the clean-up. The miserable cowards
+are hiding behind a woman. The idea makes me mad clean through.”</p>
+
+<p>“You look it,” observed Carlin. Shortly afterward he withdrew, and
+a little while later Fessenden telephoned that the safe had been
+transferred to a private yacht, moored at the foot of West One Hundred
+and Thirtieth Street. Fessenden did not know to whom the craft
+belonged. He added that it did not look as though the boat would start
+for a while, for the crew were on shore leave. Cole instructed him to
+report at once if it should appear that the yacht was about to sail.</p>
+
+<p>“They’ll probably wait till after dark,” he told himself after
+Fessenden had finished. “Rather bold of them to put it aboard a yacht
+in broad daylight. Really no reason why they shouldn’t, though,” was
+his second thought. “As far as they know, nobody suspects anything. It
+would look as if the safe was being shipped to a summer home somewhere
+along the shore. Many people keep jewelry and other valuables in
+such places, and a safe comes in handy. And to transport it by water
+on a private yacht is less risky than intrusting it to the express
+companies. There’ll be a merry little chase to-night.”</p>
+
+<p>Cole looked as if a whimsical idea had occurred to him. He called up
+Latham and inquired if the <span class="pagenum" id="Page_245">245</span>doctor owned a motor boat. The physician
+replied that he did; it was a small affair, he explained, but a demon
+for speed. Cole promised that he would learn something interesting if
+he would have the boat ready within an hour, at a certain point along
+the river. Latham’s imagination seemed to cover the gaps in Cole’s
+statement, for he promptly agreed to do as suggested.</p>
+
+<p>After giving several orders Cole left the office. His rendezvous with
+Latham was a short distance below the point where the larger craft was
+moored. Before boarding the doctor’s boat Cole went cautiously forward
+and sought out Fessenden.</p>
+
+<p>“The wind is slack, and the engine seems to be out of order,” explained
+the operative. “I believe somebody is tinkering with it.”</p>
+
+<p>“Have you learned who owns the yacht?”</p>
+
+<p>“I’ve made several inquiries, but nobody seems to know. She is
+brand-new, as you can see, and this appears to be the first time she
+has been anchored here.”</p>
+
+<p>Cole cast a glance at the queenly craft, its fresh coat of paint
+gleaming in the pale autumnal sunlight. After telling Fessenden that he
+could take the rest of the afternoon off he went back to Doctor Latham.
+The physician, looking fresh and crisp in blue coat and creamy flannel
+trousers, sat at the tiller.</p>
+
+<p>“When do we start?” he inquired anxiously.</p>
+
+<p>“We’re waiting for the other party to make the first move,” explained
+Cole, pointing out the larger boat, easily distinguishable among the
+craft of various types that littered the surface of the river.</p>
+
+<p><span class="pagenum" id="Page_246">246</span></p>
+
+<p>“Any news of Miss Brownell?”</p>
+
+<p>“Not a word, doctor. Are you in the mood for a little excitement?”</p>
+
+<p>The physician said nothing, but his smile and the squaring of his
+shoulders spoke more loudly than words. Cole glanced out over the
+horizon. A frieze of clouds was creeping up in the south, and a rising
+wind rippled the water.</p>
+
+<p>“I suppose you are armed?” he asked after a while.</p>
+
+<p>The doctor slapped his hip pocket significantly. “Are we likely to have
+a scrap?” he inquired in a tone hinting that the prospect appealed to
+him hugely.</p>
+
+<p>“Quite likely! The rats are scenting danger and crawling into their
+hole. We may have to tackle a whole nest of them.”</p>
+
+<p>The afternoon waned and still they waited. Darkness fell, and a
+spanking breeze blew up. At Cole’s suggestion the doctor moved the
+motor boat a little closer to the larger craft.</p>
+
+<p>“They are hoisting the sail,” observed Latham, as he brought the boat
+to a stop at a point from which they could watch the yacht without
+danger of being seen by its crew. Here and there the black ribbon
+of water was broken by twinkling lights. An excursion steamer swept
+majestically up the Hudson, with a tail of foaming silver in its wake.</p>
+
+<p>Presently the yacht moved. The two men in the motor boat waited a while
+to give it headway. Then the doctor flipped the wheel, and, with a
+gleeful phut-phut, the little boat darted forward. Like an <span class="pagenum" id="Page_247">247</span>animated
+thing it skipped giddily across the water, darting in and out among
+larger vessels. After a little the sprinkling of boats thinned out,
+and they hugged the shore closely, in order to avoid being seen by the
+yacht’s crew.</p>
+
+<p>“Think you can keep her in sight, doctor?” asked Cole, noticing with
+concern that the larger boat was gaining speed.</p>
+
+<p>“Easily,” said the doctor confidently, “unless the motor should start
+missing, and there’s little danger of that.”</p>
+
+<p>They were silent for a time. Cole, sitting close by, watched the intent
+look on the doctor’s face as he guided the boat along the curving river
+bank. The shore line grew more rugged; here and there earth and sky
+melted into a blur. Now and then the lights of a town threw a yellow
+sheen over the murky water. At intervals the yacht disappeared from
+view behind a jutting tongue of land, but it was never out of sight for
+long.</p>
+
+<p>“Doctor,” said Cole abruptly, “I don’t quite know what to make of you,
+but we seem to have one interest in common. Both of us are concerned
+over Miss Brownell. I am partly responsible for whatever happens to
+her, while you—— But I think you told me that your emotional self is
+dead.”</p>
+
+<p>A queer little chuckle drifted out on the breeze. There was a note of
+grim despair in it.</p>
+
+<p>“Anyhow,” Cole went on, “there is a bond of interest between you and
+me for the present. Seems we ought to understand each other a little
+better. The other night, when I trailed the hunchback to your house and
+later found him asleep on the operating <span class="pagenum" id="Page_248">248</span>table, your conduct was as
+mysterious as the deuce. What had happened?”</p>
+
+<p>The doctor, one hand on the tiller, gazed rigidly out over the black
+water to where the gray blur of a sail was visible against the darkness.</p>
+
+<p>“The thing which we call human intelligence is only a thin veneer,” he
+remarked in whimsical tones. “Sometimes only a slight thrust is needed
+to break through it. It is very amusing to watch the antics that a
+supposedly sane being will perform when a crisis of some sort comes
+along and gives him a jolt. My own part in this affair is an example
+of what happens when the veneer of intelligence cracks. You would not
+believe me if I were to tell you, so what is the use?”</p>
+
+<p>“You might try,” suggested Cole. The doctor had been a changed man
+since he learned that Miss Brownell was in danger. Before that he had
+been all subterfuge, evasions, and bewildering subtleties. Now Cole
+felt that he was face to face with the man’s real self.</p>
+
+<p>“The hunchback came to my house that night to dispatch me to a better
+world,” Latham said.</p>
+
+<p>“He had just performed a similar service for Malcolm Reeves,” Cole
+observed.</p>
+
+<p>“He had orders to get me, too. The gang feared both of us, and they had
+come to a pass where they couldn’t afford to stand on ceremony. Well,
+that night I heard some one getting in the basement way. That’s the
+advantage of being a light sleeper. I collared the fellow as he came up
+the stairs. Not knowing what to do with him I gave <span class="pagenum" id="Page_249">249</span>him a hypodermic to
+keep him quiet. Then you came and complicated the situation.”</p>
+
+<p>“If the hunchback came to your house to murder you,” said Cole
+doubtfully, “why didn’t you turn him over to the police?”</p>
+
+<p>The doctor chuckled softly. “That shows how incongruously we sometimes
+act, strutting around like hens with their heads chopped off. Your own
+conduct was very peculiar that night. I was wondering why, instead of
+handcuffing the culprit to my operating table, you didn’t telephone for
+the police wagon.”</p>
+
+<p>“I had a reason.”</p>
+
+<p>“And so did I.” The doctor chuckled again. “At least I thought I had
+a sound reason for my conduct. As a matter of fact my reason was at a
+standstill; no doubt yours was likewise. At any rate I didn’t dare hand
+the fellow over to the police. Certain things had happened that made it
+undesirable for me to communicate with the authorities.”</p>
+
+<p>“The operation on Reeves?” Cole suggested.</p>
+
+<p>Again a queer little laugh drifted out on the wind. Cole suddenly
+sat erect, gazing hard at the shadowy figure beside him. A shaft
+of intuition had suddenly pierced the fog of contradictions and
+incongruities in his mind.</p>
+
+<p>“There were two operations, weren’t there?” he asked.</p>
+
+<p>“That’s a very shrewd deduction,” declared the doctor, raising his
+voice above the roar of the wind. “There were two. I performed one
+of them. I strongly suspect that Ballinger performed the other. <span class="pagenum" id="Page_250">250</span>The
+interesting point about them is that there is an official record of the
+first, but none of the second.”</p>
+
+<p>For a moment Cole peered sharply ahead. The yacht was momentarily out
+of sight, but he caught a glimpse of it again, as they rounded a curve
+in the river bank.</p>
+
+<p>“Go on,” he said. “You were involved with this golden coterie, weren’t
+you?”</p>
+
+<p>“For a time. I thought they were engaged in strictly scientific and
+legitimate pursuits. I had known Carmody for some time, as a quiet and
+scholarly man. It was through him I became connected with the group.
+For a time all went well. My specialized training helped them solve two
+or three minor technical problems that came up in connection with their
+experiments.”</p>
+
+<p>“Then one evening Carmody telephoned me that an accident had occurred
+at his house on Bleecker Street. He asked me to come over at once.
+When I arrived he told me that Malcolm Reeves, who was visiting him
+that evening, had stumbled and fallen down the stairs. My examination
+revealed a compound fracture and convinced me that the pressure of the
+bones against the brain made an immediate operation necessary.”</p>
+
+<p>“I had Reeves removed to the nearest hospital. It happened to be one of
+the smaller private ones. I was assisted by a nurse. She was a little
+nervous, and I could see that she was new at the game, but at first I
+thought nothing of it, not until I discovered that there was something
+wrong with the anæsthetic. She had blundered in administering it. I
+shudder whenever I think of the result. Perhaps <span class="pagenum" id="Page_251">251</span>you can realize
+something of what it means to have a patient awake in the midst of an
+operation.”</p>
+
+<p>“Did Reeves see you?” asked Cole suddenly.</p>
+
+<p>The tiller wabbled for a moment in Latham’s hand. “He not only saw me,
+but he recognized me. I shall never forget the expression on his face.
+It was horrible! Well, luckily there were no serious consequences.
+After a while Reeves was brought under the anæsthetic again, and the
+operation was successfully finished. In due time he was taken to his
+home. To this day I don’t know whether Carmody told me the truth and
+the injury was accidental, or whether some one deliberately inflicted
+it.”</p>
+
+<p>“Couldn’t you tell from the nature of the wound?”</p>
+
+<p>“Not with any degree of positiveness. I suspect some one tried to
+murder him that night, but failed. Perhaps the assassin lost his nerve.
+Carmody didn’t dare to have Reeves die on his hands, and so he sent for
+me. I do know that Reeves had been troublesome toward the last, and
+that the other members of the gang were afraid of him. They had ample
+reason for wishing him out of the way, or at least rendered harmless.”</p>
+
+<p>“And so they performed a second operation that destroyed his memory?”
+guessed Cole.</p>
+
+<p>“Presumably, but that’s only a surmise on my part. Reeves recuperated
+very rapidly after the first operation. One evening, shortly after he
+became able to move about, he started out on a mysterious errand. He
+never returned, and the police found no trace of him. About the same
+time I <span class="pagenum" id="Page_252">252</span>began to grow suspicious in regard to the activities of the
+gang. I had no tangible proof, but it was my strong impression that
+their aims were not strictly legitimate.”</p>
+
+<p>“Isn’t anybody entitled to make all the gold he wants to, if he’s lucky
+enough to know how?”</p>
+
+<p>“That’s just the point. Carmody assured me he had discovered a process
+whereby real gold could be produced synthetically. It would not only
+look like gold, he told me, but it would assay up to the required
+standard when turned over to the government mints. Carmody put it so
+convincingly that at the time I believed him, especially when he showed
+me samples. Later I began to have grave suspicions. Certain things
+led me to doubt that the gang had sufficient faith in its products to
+turn it over to the government in the form of bullion. In short, I had
+reason to believe that I was involved in a huge counterfeiting project.”</p>
+
+<p>“What!” exclaimed Cole. The doctor’s revelation went beyond what he had
+learned from The Unknown Seven.</p>
+
+<p>“To eliminate all risk the gang decided to take a short cut,” Latham
+went on. “Instead of taking the gold to Uncle Sam’s mint they set up
+a mint of their own. In a short time the country will be flooded with
+spurious gold coins that are practically indistinguishable from the
+real.”</p>
+
+<p>“And you have kept silent all this time?”</p>
+
+<p>“What did I tell you about the fragile quality of our veneer of
+intelligence? I went to Carmody’s house and told him of my suspicions.
+The old fox said nothing for a time, but merely smiled that <span class="pagenum" id="Page_253">253</span>freezing
+smile of his. Then he took me to a small room on the second floor.
+There sat Reeves, a gibbering maniac. Carmody bluntly accused me of
+having performed the operation that deprived him of his reason and
+smoothly suggested that it might be well for me to keep my suspicions
+to myself.”</p>
+
+<p>“Carmody went on talking, mentioning among other things that it was
+on record that I had performed an operation on Reeves’ skull. Call me
+a simpleton if you like, but the professor’s words sank in. I guessed
+that a second operation had been performed under cover of the original
+one, but I had no means of proving it. I could see nothing but ruin
+and disaster ahead. The only one who had witnessed my operation was
+the nurse, and I could expect no help from her. I argued and argued
+with myself, but, in the end, I decided to say nothing, at least for a
+time. Sooner or later I suppose I should have spoken, but just then I
+played the coward’s part. I was very neatly caught. In what was left of
+Reeves’ mind was a picture of myself, as he had seen me when he woke
+up in the midst of the operation. Occasionally, when the recollection
+came back to him, he would shriek my name. The second operation, on the
+other hand, had been performed under circumstances so deftly arranged
+that they had left no impression whatever. There, my friend, you have
+the whole story. Sounds like a travesty, eh? I shan’t feel at all hurt
+if you refuse to believe me.”</p>
+
+<p>Cole had no reason to doubt him. What Latham had told him coincided at
+various points of contact with what he had learned at the headquarters
+of The <span class="pagenum" id="Page_254">254</span>Unknown Seven. He could piece out the rest. Agents of The
+Unknown Seven had kidnaped Reeves from the Carmody residence and taken
+him to headquarters. There he had been placed under Doctor Ballinger’s
+care, and Ballinger had gone through with the pretense of trying to
+restore Reeves’ mental functions. Only one contradiction remained.
+Since Reeves was in the hands of a physician who was friendly to the
+gang and could be depended upon to destroy any symptoms of returning
+sanity in Reeves, why had it been thought necessary to kill him?
+Ballinger himself evidently shrank from such a coarse crime as murder.
+He must have had several chances to kill Reeves by safe and subtle
+means, and yet the hunchback had been commissioned to do the crime. Why
+had Reeves been killed?</p>
+
+<p>For a while the answer to that question eluded Cole. Then he recalled
+something Carlin had told him. After Reeves had been under Ballinger’s
+care for a time, without showing any signs of improvement, it had been
+suggested that he should be removed to a hospital and a consulting
+physician called in. Evidently Ballinger had seen a danger to himself
+in that suggestion, and so the murder had been decided upon.</p>
+
+<p>“I have no reason to doubt you,” Cole said. “I don’t know but what I
+would have acted pretty much the same if I had been in your place. I
+think, though, that you have done a lot of needless worrying. Ballinger
+is not at all confident of being able to fasten the second operation on
+you.”</p>
+
+<p>“How is that?” asked Latham quickly.</p>
+
+<p><span class="pagenum" id="Page_255">255</span></p>
+
+<p>“I can’t tell you, but I have every reason to believe that Ballinger
+is afraid of what an autopsy on the body might show. Not being a
+scientific man I can’t grasp the details. All I know is that Ballinger
+is so anxious to prevent an autopsy that he is having the body spirited
+away.”</p>
+
+<p>Latham’s hand left the tiller, and the boat lurched dangerously. In a
+moment he had regained control of it.</p>
+
+<p>“Unless I am a very poor guesser,” Cole went on, “the body is on the
+yacht ahead of us. They are taking it to a place where it can be safely
+destroyed. It’s hard to do such things in the city.”</p>
+
+<p>Latham stared at him speechlessly through the dusk. The wind had
+increased, and the waves were swishing and churning against the bow of
+the little craft.</p>
+
+<p>“It may be Ballinger is suffering from an uneasy conscience,” the
+doctor murmured. “That’s one of the things that happen when the veneer
+of intelligence cracks. Conscience makes a man do queer things.
+However, if your guess is right——”</p>
+
+<p>He stopped short, at the same time peering sharply ahead. Suddenly his
+hand went out, and the chugging of the motor ceased.</p>
+
+<p>“The chase is over,” he said.</p>
+
+<p>Cole followed his glance. The yacht, with sails lowered, was turning
+into a small inlet.</p>
+
+<p>“And here is where the excitement begins,” he declared.</p>

+<div class="subheadc">THE FACE AT THE WINDOW</div>
+</div>
+
+<p class="drop-cap">WHILE Doctor Latham fastened the boat, Cole’s eyes swept the black
+masses of wooded hills that slanted upward at a sharp angle from the
+river bank. At the apex of the tallest peak a light gleamed, but
+otherwise there was no sign of human habitation on this side of the
+river. The lights of a town twinkled across the foaming welter of
+waves, and they helped Cole to fix their location. They were in one
+of the wildest and most rugged sections of Dutchess County. The peak,
+on which the solitary light shone, had once been a popular pleasure
+resort, and in the old days a cable railway had carried week-end
+excursionists to the top. Of late, what with the dry era and the
+public’s fickle fancy, the place had lost its popularity, and the
+buildings on the peak were falling into decay. The ruggedly romantic
+setting seemed an ideal one for the kind of adventure Cole anticipated.</p>
+
+<p>With the doctor at his heels, he moved cautiously toward the point
+where the yacht had anchored a short distance ahead. Of a sudden they
+stopped. The crack of a pistol rose sharply above the whine of the wind.</p>
+
+<p>“Only a signal, I think,” said Cole, after waiting tensely for a few
+moments.</p>
+
+<p>They advanced a little farther, then stopped on a slight elevation from
+which they had an unobstructed <span class="pagenum" id="Page_257">257</span>view of the yacht. In the lights from
+the craft they saw a number of men going ashore, and several of them
+were carrying a bulky object. Their faces were not recognizable at that
+distance, but Cole thought there were about a dozen in all.</p>
+
+<p>“We may have quite a lively tussle,” he observed in an undertone. “I
+could have brought a few helpers along, but safety doesn’t always lie
+in numbers.”</p>
+
+<p>“I like this better,” said Latham. “If there were more of us there
+might not be enough thrills to go around. Where are we?”</p>
+
+<p>“That place, up there in the clouds, where you see the light, is called
+Dutchess Point. I believe there is a car coming down. That’s probably
+what the pistol shot meant.”</p>
+
+<p>A light was treading its way in a zigzagging course down the side of
+the hill. Soon were heard the chugging of motors and the metallic snarl
+of brakes. The two men waited until the car reached the group that had
+come off the yacht. As soon as the loaded vehicle started to retread
+its path up the hill they followed. It proved a hard climb, and they
+reached the top a full half hour behind the car.</p>
+
+<p>The apex was composed mostly of huge flat rock, with here and there a
+few scrawny trees. There were half a dozen buildings scattered about,
+and in the largest one several lights had appeared by the time the two
+climbers reached the top. They stood in a dark spot behind a little
+cluster of starving hemlocks. No one was in sight, but the sound of
+voices drifted out to them through the open windows of the large
+building.</p>
+
+<p><span class="pagenum" id="Page_258">258</span></p>
+
+<p>“Hear that noise?” whispered Latham. “What do you suppose it is?”</p>
+
+<p>Cole listened. A gentle, rhythmic whirring was heard. He looked down at
+his feet, for it seemed to come from underground.</p>
+
+<p>“Machinery,” he said, and suddenly he remembered the words spoken by
+Malcolm Reeves in his insane glee: “Yellow—pretty yellow.” The whirring
+noise that he heard, as he stood there under the hemlocks, brought them
+back to his mind.</p>
+
+<p>“Look!” said Latham suddenly.</p>
+
+<p>Cole, following his pointing finger, glanced upward. The large
+building, he now noticed, was equipped with a high tower, and near its
+top a light had appeared in the last few moments. At the lighted window
+a face was dimly discernible. Cole strained his eyes at the point of
+illumination, and suddenly he gripped his companion’s arm.</p>
+
+<p>“It’s a woman, Latham!”</p>
+
+<p>The doctor gasped. “It must be Miss Brownell, then!”</p>
+
+<p>The two men continued staring upward. Their imaginations touched up the
+dim and remote picture which they saw with their eyes. The face was
+very white, thought Cole, and the eyes held a look of terror. She was
+looking downward; their glances met somewhere in mid-air, and yet she
+appeared not to see the two watchers below.</p>
+
+<p>“What shall we do?” asked Latham.</p>
+
+<p>“You stay here,” said Cole. “I’m going to look around a bit.”</p>
+
+<p>He slipped away among the trees, avoiding the open space in front
+of the building. The tower <span class="pagenum" id="Page_259">259</span>was in the rear, overlooking the steep
+incline, and he moved in that direction. He looked up a sheer wall
+to where the light shone. To climb up there was out of the question,
+for the blank wall offered no hold for either hands or feet. He moved
+cautiously toward the front entrance. For a moment he listened outside
+the sagging door, then boldly pushed it open and entered.</p>
+
+<p>He was in a dark corridor. Under one of the doors at the side was a
+thin wedge of light. A number of voices issued from it; evidently a
+conference of some kind was in progress. Knowing that the stairway
+leading to the tower must be in that direction, Cole tiptoed farther
+down the hall. A bold and reckless move, he had learned from
+experience, was often more effective than a thought-out plan. Before he
+could do anything else Miss Brownell must be rescued. His hands were
+tied, as long as she was held as a hostage by the gang. Once she was
+out of harm’s way he could proceed against them as ruthlessly as he
+pleased.</p>
+
+<p>He came to the end of the hall, and there he brought up against another
+door. He opened it, almost sure that it must lead to the stairs, but
+instead he found himself in a large, square room. A small electric
+bulb glowed in the ceiling, and in its light he caught a glimpse of a
+forbidding figure guarding a door at the farther side. The sentinel was
+thickset and broad-shouldered. His bushy brows seemed top-heavy for his
+very small eyes which glared out at Cole in a startled way.</p>
+
+<p>“Stop right where you are!” he commanded, at the same instant reaching
+for his hip pocket. As <span class="pagenum" id="Page_260">260</span>his fingers closed around the handle of an
+automatic, Cole lunged forward. His fist landed with explosive force in
+the man’s face, and he fell to the ground without a sound.</p>
+
+<p>“Sorry, old top, but it had to be done,” Cole told the insensible man,
+as he opened the door which the fellow had been guarding. Before him
+was a winding stairway that seemed to extend upward interminably. Very
+quickly Cole lifted the man through the door and stretched him out
+along the steps, then drew the door to.</p>
+
+<p>He hurried up the stairs. The long ascent would have exhausted a weaker
+man, but Cole’s lungs and muscles were in the pink of condition. At
+length, panting a little, he reached the top. Before him was a door. He
+rapped, and footfalls crossed the floor within.</p>
+
+<p>“Who’s there?” demanded a voice which he recognized as Miss Brownell’s.
+It sounded a bit lofty, pathetically so, he thought.</p>
+
+<p>“Cole,” he replied.</p>
+
+<p>“Oh!” The exclamation was more a sigh of relief. “But I can’t let you
+in. The door is locked, and I have no key.”</p>
+
+<p>“I might have known it,” muttered Cole. The space between the door
+and the wall of the tower was very narrow. Bracing his back against
+the wall he placed his feet on the door and shoved steadily. It was
+of stout material, but at length it gave with an abruptness that
+precipitated him to the floor. Quickly he picked himself up.</p>
+
+<p>The girl rushed toward him. There was an <span class="pagenum" id="Page_261">261</span>excited flush which
+surmounted the white of her face. “I am so glad——” she began.</p>
+
+<p>“You were foolish,” Cole sternly interrupted. “You shouldn’t have
+started after Ballinger alone. That’s no job for a woman. What
+happened?”</p>
+
+<p>“Ballinger was too clever for me,” she confessed. “The moment I thought
+I had him I was shoved into a car, blindfolded, and—— Well, that’s
+about all I know. When I opened my eyes the next morning I found myself
+here.”</p>
+
+<p>“How have they treated you?”</p>
+
+<p>“Oh, very well, suspiciously well. I have been told that prisoners who
+are doomed to die always get the best of everything. Mr. Cole, you have
+thrown a full-sized scare into the gang. I heard a couple of the men
+talking outside my door this morning. I suppose they felt sure I would
+never have a chance to repeat what I heard. They said——”</p>
+
+<p>“Not so loud!” admonished Cole.</p>
+
+<p>“I gathered from what they said,” she went on in a whisper, “that the
+leaders of the gang are badly frightened. They seem to think you are
+hot on their trail.”</p>
+
+<p>“They’re mistaken,” declared Cole modestly. “I’ve barely got started as
+yet.”</p>
+
+<p>“Well, all the same they are very much worried. Their plan, as one of
+the men put it, is to make a swift clean-up and a quick get-away. Some
+one, whom they called ‘the big chief,’ was to come out here to-night.”</p>
+
+<p>“About a dozen men arrived a little while ago,” <span class="pagenum" id="Page_262">262</span>Cole informed her. “No
+doubt the chief was among them. Do you know who he is?”</p>
+
+<p>“No. He wasn’t referred to by name in the conversation which I
+overheard. I am sure, though, that Doctor Latham isn’t the man. In fact
+I never really thought so. More of my woman’s intuition, I suppose.”</p>
+
+<p>“What else did the men say?” he asked in a whisper.</p>
+
+<p>“They said there is about half a billion dollars’ worth of gold ready
+to be minted. I didn’t quite understand what they meant by that. There
+is a complete set of machinery hidden somewhere about the place, and it
+is running at full capacity.”</p>
+
+<p>“I should think the comings and goings of the gang would excite the
+curiosity of the townspeople across the river.”</p>
+
+<p>“Oh, they’ve managed that part very cleverly by circulating a report
+to the effect that the buildings are being renovated and that Dutchess
+Point is to be reopened as a pleasure resort next spring. In fact, they
+have put a crew of carpenters, roadmakers and gardeners to work on the
+place. Just for a blind, of course. It seems they haven’t neglected a
+single precaution. Yet they seem to be worried over something.”</p>
+
+<p>“Excellent! When your enemy is worried, you have an advantage over him.
+What seems to be the trouble?”</p>
+
+<p>“I couldn’t quite make out. All I heard was a few scattered remarks. It
+appears they are having some difficulty with the gold-making process.
+There seems to be a minor flaw in the product, <span class="pagenum" id="Page_263">263</span>due to the absence of
+something which they refer as the seventh ingredient. I haven’t the
+least idea what it is, but it seems to be related to the experimental
+work Doctor Latham conducted before he severed his connection with the
+gang. They appear to think that he could solve their difficulty if he
+was so inclined.”</p>
+
+<p>“By supplying the formula for the seventh ingredient?”</p>
+
+<p>“Something like that. Anyway, that was the impression I received.
+Evidently the missing ingredient isn’t of very great importance, but
+they want to make the product as perfect as possible.”</p>
+
+<p>“For the sake of safety in minting and circulating it, I suppose,”
+said Cole thoughtfully. “Apparently Latham left them at an inopportune
+time from their point of view. Doubtless they would exert any manner
+of pressure on him in order to make him divulge the secret of this
+so-called seventh ingredient.”</p>
+
+<p>“I doubt if they would succeed.”</p>
+
+<p>“So do I,” said Cole, looking curiously at the girl. “Latham is a
+fighter clean through, and he is a match for them. By the way, he came
+out with me this evening.”</p>
+
+<p>She caught her breath and fixed her wide, troubled eyes on his face.</p>
+
+<p>“Doctor Latham here?” she murmured. “Did he volunteer to come with you?”</p>
+
+<p>“I invited him to come, and he jumped at the invitation. I foresaw that
+he would prove useful, and he was doubly anxious to come when I hinted
+that our expedition to-night might reveal your <span class="pagenum" id="Page_264">264</span>whereabouts. Your
+disappearance came as a great shock to him.”</p>
+
+<p>“Then you no longer think he is implicated with these scoundrels?”</p>
+
+<p>“No, I don’t. He was with them until he saw that their aims were
+crooked, and then he got out as best he could. Latham has acted
+foolishly, but that’s all. The scientific side of these experiments
+appealed to the scholar in him. I don’t think he was ever moved by
+greed. No, Latham wasn’t to be blamed. Whenever a man is in love he is
+apt to make a fool of himself.”</p>
+
+<p>She lowered her eyes. “Doctor Latham is a good man,” she said tensely.
+“I wish I could——” A gentle sigh escaped her.</p>
+
+<p>“I understand,” murmured Cole. “Life is a bit of a tangle, isn’t it?
+Even the logical mind of a scholar isn’t able to steer clear of the
+meshes when a charming woman is involved. One never knows——”</p>
+
+<p>He paused, threw a quick glance at the door, then looked at Miss
+Brownell, noting the tensity that had suddenly crept into her face.
+In an instant his automatic was in his hand, and he tiptoed softly to
+the door. Holding it open a crack, he heard unmistakably the sounds of
+footsteps coming up the stairs.</p>
+
+<p>“Stand back!” he ordered curtly. “Some one’s coming!”</p>
+
+<p>But the girl, smiling faintly, signified with a shrug that she intended
+to remain where she was.</p>

+<div class="subheadc">A DUEL OF WITS</div>
+</div>
+
+<p class="drop-cap">COLE opened the door a trifle wider. The footfalls, furtive and
+hesitant, sounded as if several men were coming up the protesting
+stairs. He fancied there were many others below who were ready to jump
+into the fight if he should be successful in disposing of the ones now
+approaching. His mind worked with lightning speed as he turned away
+from the door.</p>
+
+<p>The room, hexagonal in shape, with a tall window at each angle, was
+lighted from a tarnished brass fixture at one side. While watching
+the light from the outside, Cole had noticed that from the windows to
+the ground was a sheer drop of one hundred and fifty feet, so escape
+in that direction was impossible. The walls, covered with once gaudy
+paper that was now faded and torn, seemed to offer no loophole. The
+unswept floor was cluttered with pieces of dilapidated furniture of
+a kind which suggested that the room had once served as a rendezvous
+for gamblers. The single door was the only exit, and flight in that
+direction was cut off by the men now creeping up the stairs. As nearly
+as Cole could determine from the sounds, they were as yet only halfway
+up. For an instant his thoughts flew to Doctor Latham, and he wondered
+if the physician was still waiting for him outside.</p>
+
+<p>He stepped quickly toward the girl. “Talk,” he whispered, “talk about
+anything.”</p>
+
+<p><span class="pagenum" id="Page_266">266</span></p>
+
+<p>She took her cue with a comprehending nod, and Cole hastened back to
+the door.</p>
+
+<p>“But I don’t know, so how can I tell you?” she asked in a tone whose
+naturalness instantly won his approval. He was quick to follow up her
+lead.</p>
+
+<p>“You have no idea who the leader of these cutthroats is?” he asked in a
+slightly nettled tone.</p>
+
+<p>“None whatever.”</p>
+
+<p>He listened for a moment. The footsteps were coming gradually closer.
+When he spoke again, he threw his voice so that it sounded as if coming
+from the center of the room, a ventriloquial trick he had practiced
+when a boy and often found useful.</p>
+
+<p>“You have been here a good many hours,” he pointed out. “I thought you
+might have overheard something that gave you a clew.”</p>
+
+<p>“You forget that I have been locked up in this room all the time.”</p>
+
+<p>“That’s so,” Cole admitted, tightening his grip on his automatic. The
+footfalls on the stairs had ceased. Evidently the persons who were
+approaching had stopped to listen to the conversation. “You haven’t
+seen any one who looks as if he might be the boss of the outfit?”</p>
+
+<p>“No one,” she declared convincingly. “So far I have come in contact
+only with underlings. The man higher up, whoever he is, has remained in
+the background. Of course, I could make a guess.”</p>
+
+<p>“Let’s hear it.”</p>
+
+<p>“Doctor Latham.”</p>
+
+<p>Cole smiled. It was an excellent bit of strategy, and he was confident
+that the men below had heard. <span class="pagenum" id="Page_267">267</span>Her cleverly simulated suspicion in
+regard to the physician was well calculated to deceive them in regard
+to the extent and accuracy of her information.</p>
+
+<p>“You may be right,” he said thoughtfully just as the footsteps began to
+move upward again, and once more his voice sounded as if coming from
+the interior of the room. “I’ve had my eyes on the doctor myself. He is
+a sly bird, but I’m not sure that his cranium is the adequate size for
+a job of this kind. However he will bear watching. But we’re wasting
+time. The first thing to do is to get you safely out of this nest of
+crooks. I think the way is clear, but we must——”</p>
+
+<p>“You’re a little bit slow,” said a voice, and the door came open,
+admitting a stocky individual with a leveled automatic. He came
+straight forward, stopping bewilderedly as he saw only the girl, and
+in that instant Cole reached out behind him, seized him firmly by the
+neck and, swinging him backward with a powerful sweep, slammed his head
+against the wall. With a fragmentary cry the man went lurching to the
+floor, and in almost the same instant Cole whirled round and struck
+his companion a vigorous blow with the butt of his pistol. The fellow
+dropped like a dead-weight.</p>
+
+<p>“Two of them!” exclaimed Cole, feeling quite elated at the success of
+his ruse. “Where’s the third?”</p>
+
+<p>Miss Brownell, breathing rapidly, looked hard at the door. Cole glanced
+out, but there was neither sign nor sound of movement on the stairs.</p>
+
+<p>“I thought there were several of them,” he muttered. <span class="pagenum" id="Page_268">268</span>“Must have been
+mistaken. Sounds are deceptive, you know. This may come in handy.”</p>
+
+<p>He stooped, picked up the weapon dropped by his second adversary,
+and handed it to Miss Brownell. With an expert air she examined the
+mechanism, making sure it was loaded.</p>
+
+<p>“You worked the trick to the queen’s taste, Miss Brownell,” he declared
+approvingly. “It was a good piece of work.”</p>
+
+<p>“But you did it all.”</p>
+
+<p>“Far from it! I couldn’t have thrown them off their guard if you hadn’t
+helped. Do you know,” peering at her curiously, “I was afraid you would
+faint, or something like that.”</p>
+
+<p>She laughed. “You haven’t a very high opinion of our sex, Mr. Cole.”</p>
+
+<p>“It is rising every moment. We must get away before these rascals come
+to. Feel strong enough for a walk?”</p>
+
+<p>“Just try me! Your exhibition of fisticuffs was so stimulating that I
+am ready for anything.”</p>
+
+<p>“Then let’s start. Latham must be wondering what has become of me.”
+With a glance at his fallen foes, Cole started down the stairs, the
+girl following. He did not wish to alarm her by voicing his misgivings,
+but he was far from certain that they would reach the bottom without
+an interruption. Doubtless the others must be aware by this time that
+something was amiss. The burly sentinel he had knocked down at the foot
+of the stairs had probably either recovered consciousness or been found
+by his accomplices. In either event, their path was beset by perils.</p>
+
+<p><span class="pagenum" id="Page_269">269</span></p>
+
+<p>Pistol in one hand, Cole proceeded cautiously down the stairs. They
+were dark, and the constant winding made progress difficult. He had
+discovered that Miss Brownell was brave and resourceful, but he would
+breathe more easily when he had got her out of harm’s way.</p>
+
+<p>They reached another turn, and suddenly the girl stumbled and lurched
+violently against him.</p>
+
+<p>“Ouch!” she moaned, trying to repress an exclamation of pain. “My
+ankle! I think I twisted it.”</p>
+
+<p>Cole cursed softly as he gathered her in his arms. Her figure was
+writhing in the throes of physical distress.</p>
+
+<p>“As I told you once before,” she complained mockingly, trying to make
+light of the injury, “you are not at all gallant. Almost any other man
+would have welcomed the chance.”</p>
+
+<p>Cole muttered something under his breath. A dislocated ankle
+complicated a situation that was already critical enough, but the
+girl’s superb behavior stirred him to unwilling admiration. His fears
+were all for her, not for himself. He was almost at the foot of the
+stairs now. If he could only get her safely out of the building and
+place her in Doctor Latham’s care. If only——</p>
+
+<p>Abruptly he stopped before a door. With his burden in his arms he had
+reached the foot of the stairs. For a moment he stopped and listened,
+but all seemed quiet on the other side. An involuntary moan of pain
+told that Miss Brownell was suffering intensely. Balancing her on his
+shoulder he reached out a hand and pushed the door open.</p>
+
+<p><span class="pagenum" id="Page_270">270</span></p>
+
+<p>Instantly he felt a premonition that something was wrong. The sentry,
+whom he had left unconscious at the door before ascending to the tower,
+was no longer there. He started to draw back, but it was too late. A
+shadow leaped swiftly across the path of light in front of the open
+door. A hand clutching a bludgeon was raised to strike. Cole, with
+the girl on his shoulder, could not dodge the blow. It caught him
+squarely on the jaw, and the terrific impact sent him reeling against
+the stairs. The girl slipped away from him, and in his last conscious
+moment he tried to ease her fall.</p>
+
+<p>“I take it all back,” she whispered in his ear, her bantering tone
+edged with pain and anguish. “You—you <i>are</i> gallant, Mr. Cole.”</p>
+
+<p>But Cole heard nothing.</p>

+</div>
+
+<p class="drop-cap">WHEN, some thirty or forty minutes later, Cole opened his eyes and
+fingered his swollen jaw, he found himself sprawling in a chair in
+a strange room. In front of him stood Doctor Latham, a humorously
+sympathetic look on his face.</p>
+
+<p>The room, with its faded tawdriness and crumbling decorations, looked
+as if it had once been a private dining room. The scratched woodwork
+and the liquid stains on the wall paper were reminiscent of hilarious
+times. Cole noticed that the two windows were shuttered on the outside.</p>
+
+<p>“How do you feel?” inquired the physician.</p>
+
+<p>“As if I was all jaw,” said Cole, opening his eyes a little wider and
+gazing stupidly at the doctor. It took him several minutes to recall
+that he was still in the big house on Dutchess Point. A rhythmic
+vibration that seemed to come from beneath the floor, accompanied by
+the remote humming of machinery, brought him back to the present.</p>
+
+<p>“Why are you here?” he demanded of the physician. “Didn’t I tell you to
+stay outside?”</p>
+
+<p>“So you did, and it was excellent advice, my friend. I wish now I had
+heeded it. But I grew impatient and proceeded to find out what had
+become of you. All I got for my pains was an ungentle tap in the region
+of the occipital bone.”</p>
+
+<p>With a serio-comic expression the doctor caressed <span class="pagenum" id="Page_272">272</span>the back of his
+head. His clothing was rumpled and looked as if he had been dragged
+over a dusty floor.</p>
+
+<p>Again Cole stroked his jaw. “Where is Miss Brownell?” he suddenly asked.</p>
+
+<p>Latham pointed across the room where, white-faced but smiling, the girl
+sat in a chair.</p>
+
+<p>“I’ve justified my existence at last,” he remarked. “I managed to
+straighten out Miss Brownell’s ankle. Didn’t have my kit with me, and I
+fear I dealt rather roughly with her. How about it, Miss Brownell?”</p>
+
+<p>“I hardly felt it,” she assured him. “For a big man, you are gentleness
+itself.”</p>
+
+<p>The physician looked long into her smiling face, and when he turned
+away there was a sad, wistful expression in his eyes. Miss Brownell
+caught a fleeting glimpse of it, and her face sobered instantly.</p>
+
+<p>“Cheerful place!” murmured Latham, glancing up at the dilapidated
+ceiling. “Anyway, we ought to be thankful that the three of us are
+together. Wonder what the amiable ruffians plan to do next. What
+happened to you after you left me, Cole?”</p>
+
+<p>It took Cole some little time to remember, but at length he gave the
+doctor a brief summary of the episode in the tower, ending with the
+unexpected attack that had left him with a swollen jaw. The doctor
+seemed amused.</p>
+
+<p>“Laid them both out, eh?” he said with a chuckle. “Good work, Cole.
+I believe you could manage a massacre all by yourself if you had the
+chance.”</p>
+
+<p>“The chance may come sooner than we think,” said Cole dryly, with a
+glance at the door. “Miss <span class="pagenum" id="Page_273">273</span>Brownell told me some of the things she has
+learned during her term of imprisonment here. It seems we have one
+advantage, doctor.”</p>
+
+<p>“What’s that?”</p>
+
+<p>“The seventh ingredient.”</p>
+
+<p>A thin smile parted the physician’s lips. “That’s so. I’d forgotten
+about that. It’s a minor detail I worked out independently. Professor
+Carmody made several attempts to make me reveal the secret of it, but
+I refused. You see, by that time I had discovered that the scheme was
+crooked, and I would have nothing more to do with the gang. However,
+the seventh ingredient, as they call it, isn’t of great importance. Its
+value is almost nil.”</p>
+
+<p>“But they seem to think otherwise.”</p>
+
+<p>“They are mistaken, and naturally so. I was mistaken myself for
+a while. I exaggerated the importance of the so-called seventh
+ingredient. Afterward, when I knew better, I saw no reason why I should
+put them right.”</p>
+
+<p>“Glad you didn’t, Latham. As long as they are laboring under a
+misapprehension, we have an advantage over them.”</p>
+
+<p>“How is that?”</p>
+
+<p>“They think you have something that they want. The fact that they are
+mistaken makes no difference. As matters stand at present, you are in a
+position to bargain with them.”</p>
+
+<p>“Bargain over what?”</p>
+
+<p>“Oh, several things.” Cole stepped a little closer to him and spoke in
+an undertone. “Miss Brownell’s safety, for instance.”</p>
+
+<p>Latham’s brows went up. “Of course!” he murmured. <span class="pagenum" id="Page_274">274</span>“I’m a bit dull
+to-night. Glad you have your thinking cap on, Cole. The amiable
+ruffians will be given to understand that I refuse to discuss the
+seventh ingredient until Miss Brownell is at a safe distance. After
+that nothing will matter. Smoke?”</p>
+
+<p>Cole helped himself to a cigarette from the physician’s case, slanting
+a quick glance in the girl’s direction as he lighted it. She looked
+both puzzled and amused.</p>
+
+<p>“Were you saying something I was not supposed to hear?” she inquired.</p>
+
+<p>The question remained unanswered, for just then the door opened, and
+the gaunt, frock-coated figure of Professor Carmody strutted into the
+room. In his hand was an automatic, which he managed very cautiously,
+and his shrunken face was all smiles.</p>
+
+<p>“Hello, Cole,” he chirped gleefully. “Good evening, Miss Brownell. How
+are you, doctor? Glad to see you all here.” He chuckled wheezily and
+rubbed his bony hands with their talonlike fingers. “Too bad you didn’t
+follow my advice the other day, Latham. You would have escaped a lot of
+trouble if you had been sensible.”</p>
+
+<p>“Go to blazes,” said the doctor contemptuously, advancing a step toward
+Carmody.</p>
+
+<p>The pistol came upward in the professor’s hand. “Don’t move,” he
+warned. “And it won’t do either of you any good to reach for your
+weapons. They were removed while you were—ahem—incapacitated. We object
+to rowdyism in this place. Our leader is a peaceful man and does not
+like disturbances. Cole, you have caused us a lot of embarrassment,
+<span class="pagenum" id="Page_275">275</span>and see what it has led you to. I believe our last meeting took place
+in room 2512, the Security Building.”</p>
+
+<p>Cole made a wry face as he recalled how the professor had tricked him.
+“You were a bit too clever for me that time, Carmody,” he admitted.</p>
+
+<p>The professor gave a cackling, complacent laugh. “Even an old man like
+me must have his little jokes,” he remarked, still adhering to his
+ludicrous habit of raising and dropping his voice on almost every other
+word. “I’ll wager you don’t know even now what my object was. Eh, Cole?”</p>
+
+<p>Cole measured him with a cool glance. “I think I do,” he declared
+quietly. “The body of Reeves was in the safe. Members of your
+illustrious gang had removed it from its former place and put it there.
+One of my men learned what the safe contained, and he paid with his
+life for his discovery. Later you dropped in to see that everything was
+in readiness to sneak the safe and its contents out of town.”</p>
+
+<p>“You are a very shrewd guesser, Mr. Cole. It is a matter of keen regret
+to me that one of such fine intellect must be on the wrong side of this
+situation. As for the body of Reeves, it will very soon be reduced to a
+handful of fine dust. The process will be scientific in every respect.
+Nothing coarse or gruesome, you understand. We couldn’t have disposed
+of it satisfactorily in the city. It would have been too dangerous.
+But that isn’t what I came in here to talk about. Doctor Latham, you
+were once a friend of mine, and in the beginning of this enterprise
+you gave us several valuable hints. <span class="pagenum" id="Page_276">276</span>For the last time I ask you to be
+reasonable. It is your last chance.”</p>
+
+<p>“And if I refuse?”</p>
+
+<p>The professor screwed his face into a melancholy expression. “In that
+event you, too, will soon be only a handful of dust.”</p>
+
+<p>“Even so I will have the advantage over you, professor. When your end
+comes there won’t be enough dust to make a thimbleful. I hope I make my
+meaning clear?”</p>
+
+<p>“You will not reconsider your decision?”</p>
+
+<p>“No!” declared Latham explosively.</p>
+
+<p>“Not even in order to save the life of this charming young lady?”
+Carmody turned his beatifically smiling face toward Miss Brownell.</p>
+
+<p>A pallor crept up under the doctor’s eyes. He stared with a horrified
+expression at the professor.</p>
+
+<p>“You mean that——”</p>
+
+<p>“Precisely, my dear doctor. The young lady is dangerous to us.
+Under the circumstances the law of self-preservation demands that
+she be rendered harmless, and the only effective way of doing that
+is to remove her from this sad world. However, in appreciation of
+the services you once rendered us, she shall be spared if you will
+reconsider your decision.”</p>
+
+<p>The doctor appeared to hesitate. His eyes, full of tenderness, were
+fixed on Miss Brownell. Cole could see that he pretended to be
+wavering. Then the girl spoke.</p>
+
+<p>“Doctor Latham has decided,” she declared in a clear, calm voice. “He
+is not the type of man who bargains with blackguards. I wouldn’t permit
+<span class="pagenum" id="Page_277">277</span>it, even if he were so inclined. Go away!” she added, turning her
+eyes, full of cold contempt, on the professor.</p>
+
+<p>Carmody winced beneath her scornful gaze. For a moment he plucked
+nervously at the lapel of his coat. Then, with a soft chuckle that
+sounded diabolical to the other three in the room, he turned to the
+doctor.</p>
+
+<p>“The young lady has spoken,” he remarked. “I’m afraid her pretty head
+is full of silly notions. Youth is always like that. You are older and
+wiser, Latham. What do you say?”</p>
+
+<p>The doctor regarded him calculatingly. “Just what do you want, Carmody?”</p>
+
+<p>“Ah, that’s better! Getting down to terms, eh? I see I was not mistaken
+in relying on your common sense. You know what I want, doctor. It is
+something we have discussed before. Miss Brownell and Mr. Cole will not
+understand what I mean, but it has something to do with the seventh
+ingredient.”</p>
+
+<p>Latham nodded. “Thought so. Very curious on that point, aren’t you,
+professor? I used all my spare time during three or four months working
+out that interesting angle. It was quite fascinating, I assure you. Do
+you know, professor, I sometimes wonder if the late lamented Doctor
+Price was not about two hundred years ahead of his time? From the very
+beginning of our experiments I suspected that Doctor Price’s secret—the
+secret which he never divulged—was a sort of electronic reaction
+applied to chemical compounds. When I <span class="pagenum" id="Page_278">278</span>learned how to use that reaction
+in the process we had under way, my problem was solved.”</p>
+
+<p>Carmody regarded him narrowly. “The electron wasn’t known in Doctor
+Price’s day.”</p>
+
+<p>“And that’s why I say he was about two centuries ahead of his time.
+At any rate, I am satisfied he stumbled upon something which closely
+resembles our modern discoveries. Nothing else explains the marvelous
+achievement that he took with him to his grave.”</p>
+
+<p>“And you claim to have resurrected his discovery, Latham?”</p>
+
+<p>“I am not in the habit of making claims,” said the doctor modestly,
+with an air of mysteriousness that was well calculated to impress
+Carmody. “I prefer to let facts speak for themselves.”</p>
+
+<p>Carmody pondered, his sharp, greedy little eyes wandering from one face
+in the group to another.</p>
+
+<p>“You made memoranda of your experiments, of course?”</p>
+
+<p>“Naturally.”</p>
+
+<p>“Where are your notes?”</p>
+
+<p>Latham smiled blandly. “In two places. Here,” tapping his head, “I
+carry the whole process. My written memoranda are in a safe place, a
+place which I shan’t divulge to you until you have given us reasonable
+guarantees in regard to our safety.”</p>
+
+<p>Professor Carmody scowled. “You are hardly in a position to dictate
+terms.”</p>
+
+<p>“Do as you like,” said Latham with a shrug. “If you reject my
+conditions, I shall follow Doctor Price’s example and take my little
+secret with me to my grave.”</p>
+
+<p><span class="pagenum" id="Page_279">279</span></p>
+
+<p>“And what about Miss Brownell?”</p>
+
+<p>The physician winced, but before he could answer the girl spoke for
+herself.</p>
+
+<p>“Don’t mind me,” she said spiritedly. “Doctor Latham, why don’t you
+tell the professor that he is beneath contempt?”</p>
+
+<p>Carmody turned his head and regarded her with a look of lofty disdain.
+“Haughty little devil!” he muttered under his breath, then faced
+the physician again. “Well, Latham, what would you call reasonable
+guarantees?”</p>
+
+<p>“Cole and myself will remain here for the present. As far as Miss
+Brownell is concerned, I’ll be satisfied when she telephones me from
+her home in town that she has arrived there safely. Does that strike
+you as reasonable, Cole?”</p>
+
+<p>“Perfectly.”</p>
+
+<p>Carmody scratched his jaw perplexedly. “It is a very difficult
+situation. I shall refer it to the leader of our organization.”</p>
+
+<p>With that he backed cautiously toward the door, his automatic gripped
+tightly in his thin, gnarled hand. In a moment the door closed behind
+him, then came the sound of a heavy bolt turning in the lock, and the
+two men and the girl were alone.</p>

+</div>
+
+<p class="drop-cap">COLE turned to the window and verified his impression that the
+shutters were strong enough to bar their exit in that direction. For
+a few moments he stood there, listening to the remote booming of the
+waves, the fretful whine of the wind, the creaking and groaning of
+timbers in the old house. With these sounds there mingled another, a
+faint but ecstatic humming and whirring that seemed to come from some
+subterranean crypt.</p>
+
+<p>“Gold!” it seemed to say with a dull, sinister intonation. “Gold!”</p>
+
+<p>Cole shrugged and moved away. Next he hurled himself against the
+door, but its solid resistance told him the effort was useless. The
+doctor stood in the middle of the room, pulling thoughtfully at his
+black beard and now and then sending Miss Brownell a glance out of his
+strange, flashing eyes.</p>
+
+<p>“You handled the professor superbly,” Cole told him. “He is guessing
+now, and when a man is guessing he is at a distinct disadvantage.”</p>
+
+<p>The doctor smiled musingly. “But don’t build too high hopes on his
+state of mind,” he cautioned. “It is best not to underrate the enemy’s
+resources.”</p>
+
+<p>“What about that choice morsel you handed him in regard to an
+electronic reaction?” Cole wanted to know. “Anything in it?”</p>
+
+<p>“Absolutely nothing. But it sounded impressive enough to give the
+professor something to worry <span class="pagenum" id="Page_281">281</span>about. As for Doctor Price, he wouldn’t
+have recognized an electron if he had seen one with the naked eye. I
+hardly expected Carmody to swallow it, but he did. When you tell a fib,
+it is always best to tell the kind that the other fellow is prepared to
+believe.”</p>
+
+<p>Cole laughed; there was something irresistible about the doctor’s
+stoicism. “I hope,” he fervently declared, “that the swallowing of that
+electron will give the professor a severe attack of cramps. What do you
+propose to do next, Latham?”</p>
+
+<p>“Heroics were never in my line,” the doctor asserted in a tone that was
+meant to be cynical. “When one is caught, the thing to do is to yield
+as gracefully as possible. I suggest we surrender to the enemy. Why
+stand on pride when one is headed for a tumble?”</p>
+
+<p>“In other words, you mean to build up a magnificent bluff on the
+electron Carmody swallowed?”</p>
+
+<p>“Precisely,” said Latham, casting a sidelong glance at Miss Brownell.</p>
+
+<p>The girl got up, limped uncertainly across the floor, and placed a hand
+on the physician’s arm.</p>
+
+<p>“You are a good man, Doctor Latham,” she murmured. “You are quite
+transparent, however. You intend to keep up this bluff, as you call it,
+until I am at a safe distance. You fail to consider what is going to
+happen to you and Mr. Cole when they discover you have tricked them.”</p>
+
+<p>“Oh, we will cross that bridge when we come to it,” said Latham with an
+air of profound assurance.</p>
+
+<p>“You aren’t candid with me,” the girl protested. “You know they will
+kill you both as soon as they <span class="pagenum" id="Page_282">282</span>realize they have been imposed upon. You
+intend to sacrifice yourself for my sake. I won’t have it!”</p>
+
+<p>“Now, Miss Brownell——”</p>
+
+<p>“I won’t accept such a sacrifice,” she declared vehemently. “That’s
+absolutely final.”</p>
+
+<p>Latham gazed at her in an embarrassed way. He tried to smile, but it
+was a pathetic effort. “Youth is always that way,” he declared. “Always
+butting its head against stone walls. Don’t you see, Miss Brownell,
+that——”</p>
+
+<p>“No, I don’t,” she interrupted. “And, so you won’t be tempted to give
+it for my sake, let me tell you that I intend to fight this crowd of
+cowardly ruffians till the end. Even if you should surrender, I would
+not, so your sacrifice would be in vain.”</p>
+
+<p>Latham stroked his beard reflectively. A flippant remark was on the tip
+of his tongue, but he seemed unable to utter it. He assisted the girl
+back to her chair.</p>
+
+<p>Cole had watched them in silence. Something stirred gently within him
+as he witnessed the scene between the doctor and the girl. There was
+a touch of the sublime in the physician’s determination to sacrifice
+himself for the object of his hopeless devotion. But to Cole it all
+seemed very futile. He doubted strongly that the leader of the gang
+would accept Latham’s terms. Knowing that she had discovered several
+important things in regard to the organization’s activities, they would
+not be likely to let the girl out of their clutches. Their logical
+move would be an effort to obtain by other means the secret which they
+supposed was in Latham’s <span class="pagenum" id="Page_283">283</span>possession. Nevertheless, the little drama
+enacted before his eyes touched him deeply. Now he shrugged off his
+hopeless feeling and strode briskly across the floor.</p>
+
+<p>“It isn’t time to sing the funeral hymn just yet,” he declared. “There
+is another fight in us still. I propose that we——”</p>
+
+<p>What he had to propose was not made clear, for the door opened, and
+with his usual stiff and dignified gait Professor Carmody walked once
+more into the room. He had dropped his mock affability and carried
+himself with a stern and dignified air.</p>
+
+<p>“I have talked with the chief,” he announced, addressing Doctor Latham.
+“The arrangement you suggested is flatly impossible.”</p>
+
+<p>“Just as I thought,” muttered Cole under his breath.</p>
+
+<p>“You can see for yourself how unreasonable it is,” Carmody went
+on in an argumentative tone. “Miss Brownell is in possession of
+information which, if used against us, might harm us greatly. Under the
+circumstances it would be extreme folly on our part to permit her to
+leave this place for the present.”</p>
+
+<p>“Then what do you propose?” asked the doctor.</p>
+
+<p>“That you listen to reason. In a few days, a week or two at most, our
+present enterprise will be finished, and we shall be in a position
+where nothing can hurt us. You, Latham, can hasten developments, if you
+wish, by giving us the formula you have worked out. It isn’t essential,
+but we prefer to make use of it. The sooner you choose to oblige <span class="pagenum" id="Page_284">284</span>us,
+the sooner you and your friends will be permitted to depart.”</p>
+
+<p>The doctor regarded him with a half-humorous, half-contemptuous gaze.
+“Is that all?”</p>
+
+<p>“By no means. If you decide to accommodate us, you shall share in
+the golden harvest we soon expect to reap. Think of it, Latham. By
+complying with a simple request you will make yourself enormously
+wealthy. Never before in the world’s history was such a magnificent
+reward offered for a comparatively small service. Never since——”</p>
+
+<p>“You are waxing rhapsodical, professor,” interrupted Latham curtly. “I
+am always suspicious of a man who makes flowery promises. Will you tell
+me in plain words—the plainer the better—what will happen if I should
+reject your magnanimous offer?”</p>
+
+<p>“I do not like to contemplate it,” said Carmody, his face full of
+sadness. “Especially in view of Miss Brownell’s connection with the
+matter. But you will not do anything so foolish, Latham. Remember
+that we are powerful enough to get what we want, and that we do not
+hesitate to use extreme measures when necessary. We can bend even such
+a stubborn will as yours. I am waiting for your answer. Will you give
+us the formula voluntarily, or must we resort to unpleasant forms of
+coercion?”</p>
+
+<p>Maintaining a firm hold on his pistol, he struck an expectant attitude.
+Cole, who had remained a silent but attentive listener, could see that
+Latham’s position in the scientific world, together with the work he
+had previously done for the organization, <span class="pagenum" id="Page_285">285</span>had convinced the professor
+that he really possessed a formula that would be of great value to
+the gang. Latham, on the other hand, seemed in a quandary as to how
+he might best use his precarious advantage. Already it was slipping
+away from him, and soon, unless an unforeseen development came to his
+rescue, it might be turned against him.</p>
+
+<p>“You are taking a long time,” complained the professor.</p>
+
+<p>“It is a weighty question,” rejoined Latham.</p>
+
+<p>“Perhaps I can help you to arrive at a decision,” said Carmody, a
+faint, cruel smile parting his bloodless lips. Suddenly he shifted the
+aim of the pistol so that the barrel pointed straight to Miss Brownell.
+“I believe you are a man of your word, Latham. I shall count ten.
+Unless you give me a favorable reply before I reach ten, Miss Brownell
+will go to a better world.”</p>
+
+<p>The sardonic grin that had twisted the doctor’s lips froze into a
+ghastly look of horror. Miss Brownell straightened a little in her
+chair, her face turned a shade paler, but there was no fear in the
+eyes she leveled at the professor. Critical as the moment was, Cole’s
+dominant sensation was admiration for her courage.</p>
+
+<p>Carmody began to count in his thin, brassy voice: “One—two—three—four——”</p>
+
+<p>Cole gazed narrowly into his face, as impassive as if carved out of
+wood. There seemed to be no doubt but what Carmody meant to carry out
+his monstrous threat. He flexed his muscles for a spring while the
+professor went on counting.</p>
+
+<p>“——five—six—seven—eight——”</p>
+
+<p><span class="pagenum" id="Page_286">286</span></p>
+
+<p>Cole lunged forward, staking everything on the chance of snatching
+the murderous weapon from the professor’s hand, but Doctor Latham
+acted even more quickly. With a sudden bound he crossed the floor and
+placed himself directly in front of the chair in which the girl sat.
+For a moment the pistol pointed straight at his midriff; then, with an
+exclamation of baffled rage, Carmody lowered the weapon.</p>
+
+<p>“Fool!” he snarled. “Step out of the way this instant, or I’ll kill
+both of you.” Once more the pistol rose in his hand.</p>
+
+<p>Very calmly, while Cole marveled at his audacity, Latham took a case
+from his pocket and with ostentatious serenity lighted a cigarette.</p>
+
+<p>“Fire away,” he said coolly, folding his arms across his chest and
+smoking with an air of perfect content.</p>
+
+<p>Carmody regarded him with a baleful glare, then abruptly changed his
+mind and started backing toward the door. He slammed it behind him with
+unnecessary vigor, and they heard the bolt slide in the lock. Latham
+flung away his cigarette.</p>
+
+<p>“Whew!” he exclaimed. “That was fairly exciting. I didn’t like the way
+Carmody looked when he left us, though. The old rat has something up
+his sleeve.”</p>
+
+<p>Cole nodded, wondering at the meaning of the professor’s hasty exit.
+“Our only hope is to spar for time, and we have been fairly successful
+so far,” he remarked. “That was a neat maneuver, Latham.”</p>
+
+<p>“It was splendid!” exclaimed the girl, and Cole <span class="pagenum" id="Page_287">287</span>noted a new expression
+in her wide, lustrous eyes as she fixed them on the physician. “But you
+mustn’t do it again,” she added firmly. “He might shoot next time.”</p>
+
+<p>“How is the foot?” inquired Latham.</p>
+
+<p>“Better—much better. I think I can step down on it now.”</p>
+
+<p>“You had better not try as yet,” said the physician with a professional
+air. “Cole and I may challenge you to a foot race by and by, and you
+must preserve your energies.”</p>
+
+<p>She merely smiled at this, and again Cole noted the new, tender
+expression in her face. He was about to frame a remark, but just then
+the door opened. Two burly, hard-faced men, each with an automatic in
+his hand, entered the room.</p>
+
+<p>“The big chief wants to see you,” announced one of them. “This way.” He
+pointed toward the open door.</p>
+
+<p>Cole glanced narrowly at the weapon in his hand, then decided that
+at the present moment resistance would be worse than useless. There
+were other lives besides his own to be considered. Evidently the same
+thought had occurred to the doctor. After a moment’s hesitation and an
+exchange of glances with Cole, he took the girl in his arms and carried
+her out followed by Cole.</p>
+
+<p>One of the armed men, walking at the head of the little procession,
+opened the door.</p>
+
+<p>“In there,” he directed. “Step lively!”</p>
+
+<p>He gave Cole an ungentle shove with his automatic, and the three
+prisoners walked through the door.</p>

+<p class="drop-cap">COLE glanced about the room they had entered. Its sparse furnishings
+suggested that it had been arranged in haste. There were a desk and
+a telephone, hinting that it served as the executive office of the
+gold-mad crowd, also a few chairs, a huge steel safe, and a cot. The
+cluttered condition of the desk indicated that some one had recently
+been sitting there and would probably soon return. Cole’s gaze rested
+longingly on the telephone, the only connecting link with the outside
+world.</p>
+
+<p>Very gently Doctor Latham placed the girl in one of the chairs. As she
+looked up at him, her eyes were full of trust and gratitude.</p>

+<p>“Where is the benevolent gentleman whom you call the big chief?” he
+inquired.</p>
+
+<p>“You’ll see him soon enough,” replied the man surlily.</p>
+
+<p>“Good!” exclaimed Latham. “At last my curiosity shall be satisfied. We
+have a pretty good idea what he looks like—eh, Cole?”</p>
+
+<p>“I think we do,” said Cole, a smile tugging at his lips. “Once or twice
+before my suspicions turned in the direction of the man I have in mind,
+but something threw me off the track. Now I am almost sure.”</p>
+
+<p><span class="pagenum" id="Page_289">289</span></p>
+
+<p>Cole’s next words were spoken in an undertone, too low for the girl to
+hear. “You realize what you are up against, don’t you, Latham?”</p>
+
+<p>“Against a bunch of cockeyed devils, of course.”</p>
+
+<p>“I had something more specific in mind. Professor Carmody has failed
+to bully us, so now the big chief himself is to have a try at it. You
+realize, of course, that he wouldn’t allow himself to be seen by us
+unless——” He paused and looked gravely at the doctor.</p>
+
+<p>“Yes, I understand,” whispered Latham, throwing an uneasy glance at
+Miss Brownell. “He wouldn’t show himself to us if he thought there was
+the slightest chance that we would ever tell tales about him. These
+scoundrels are planning to murder us, Cole.”</p>
+
+<p>“So it looks, but not until they have made one more effort to make you
+reveal the formula for the seventh ingredient.”</p>
+
+<p>There was a look of sad humor in the doctor’s eyes. “And next time they
+will try harder. I’ll keep up the bluff as long as I can. The seventh
+ingredient!” He chuckled grimly under his breath. “Like most humbugs,
+it sounds well.”</p>
+
+<p>Cole glanced expectantly toward the door. “A little while ago, out in
+the other room, when you stepped between Carmody’s pistol and Miss
+Brownell, did you expect the professor would shoot?”</p>
+
+<p>“I didn’t know what to expect, to tell the truth.”</p>
+
+<p>“Well, I knew he wouldn’t,” said Cole emphatically. “While we are
+waiting, you might try to figure out the reason why. When you find it,
+file it away in your mind for future reference. <span class="pagenum" id="Page_290">290</span>It may come in handy.
+We must stop this whispering. We are making Miss Brownell nervous.”</p>
+
+<p>A slight sound was heard in the corridor. The two armed guards stood
+aside, and then the door opened. A moment later, smiling thinly as he
+saw his suspicions confirmed, Cole faced the leader of the alchemists.</p>
+
+<p>“Good evening, Mr. Englebreth,” he said easily.</p>
+
+<p>An attendant pushed the invalid’s wheel chair up to the desk.
+Englebreth, his disproportionately broad shoulders slightly hunched,
+looked about the room with a rather listless expression. He was as
+white-faced as ever, and his pale, washed-out eyes showed little
+animation, but a faintly sinister smile played about the long, thin
+lips. In his hand was a pistol with which he toyed with apparent
+carelessness.</p>
+
+<p>He nodded at Cole, then, with a quick motion of his long, slim fingers,
+dismissed his attendant. The door closed, and the two armed guards
+stood in front of it. For a while no one spoke. A hush seemed to have
+descended over the little group with the invalid’s entrance. Latham
+regarded him intently, but without a sign of surprise. For a moment
+Englebreth’s pale eyes rested on Miss Brownell, then he glanced at the
+doctor, and finally at Cole. His forehead puckered a little.</p>
+
+<p>“You do not seem surprised to see me,” he remarked petulantly, as if
+disappointed that his entrance had created no sensation.</p>
+
+<p>“Why should I be?” Cole asked.</p>
+
+<p>“Surely you didn’t suspect until now that I was connected with the
+enterprise on foot here?”</p>
+
+<p><span class="pagenum" id="Page_291">291</span></p>
+
+<p>“On the contrary,” said Cole, “your entrance has only confirmed the
+suspicions that have been running in and out of my head for the past
+two days. They began when I saw you enter the offices of the Bureau of
+Civic Research. They received a setback when I learned that the letters
+you left on the desk were genuine.”</p>
+
+<p>Englebreth seemed mildly amused. “I am a public-spirited man,” he
+declared. “The Bureau of Civic Research is one of the numerous
+praiseworthy activities I am interested in. Being one of its honorary
+vice presidents I have free access to its headquarters, of course. When
+I learned, quite by accident, that a certain mysterious organization,
+located on the top floor of the building, was resisting my plans, then
+this privilege stood me in good stead. You might have guessed, Cole,
+that I left those letters for a blind, just to show any casual visitor
+that everything was open and aboveboard.”</p>
+
+<p>“I might,” said Cole dryly.</p>
+
+<p>“Yet you have proven yourself a very fair guesser, I must say. You are
+a clever fellow, Cole. The Unknown Seven didn’t become really dangerous
+to us until you took charge of its activities. Not that you have
+accomplished anything,” he added with a dry chuckle. “We are too strong
+even for you.”</p>
+
+<p>Cole received the compliment with a shrug. A silence fell between them.
+In the stillness the rhythmic humming of machinery was distinctly
+heard. In Cole’s ears it sounded like a pæan of gold. He looked deep
+into Englebreth’s pale eyes. There was a queer flicker in the depths,
+an expression <span class="pagenum" id="Page_292">292</span>of insatiable greed to which the subterranean whir
+and throw was but the audible accompaniment. He had seen the same
+expression in Reeves’ burning orbs and also in the eyes of Carmody and
+Ballinger. There was something abysmal about it. It suggested one who,
+having gazed too long on visions of great wealth, had become enslaved
+to a fearful obsession.</p>
+
+<p>“Yes, you are very clever,” Englebreth went on. “It did not occur to me
+that any one might suspect what the safe contained, but evidently you
+did. You followed the yacht, of course. It was a very ingenious move,
+Cole. Without doing so you would never have located our establishment
+here. Now that you are here what do you propose to do?”</p>
+
+<p>Cole only smiled. Again he looked deep into Englebreth’s eyes and saw
+the smoldering fires of the fever of gold.</p>
+
+<p>“My wife is an admirer of yours, Cole,” the invalid went on. “When her
+brother disappeared she insisted that I engage you to find him. Of
+course I couldn’t very well refuse. It would have looked suspicious,
+and, besides, I supposed you were harmless. When I saw that you were
+about to learn too much, through your connection with me, I succeeded
+in persuading my wife that you were not worthy of confidence, that it
+was best to dismiss you. Again I ask you what you intend to do.”</p>
+
+<p>The words sounded like a taunt. Again Cole slanted a glance at the
+telephone. The instrument tantalized him. He noticed that the green
+cord attached to its base was of generous length. His mind worked
+quickly, but the sight of the three <span class="pagenum" id="Page_293">293</span>automatics baffled him. A sudden
+move would mean instant death, not only for himself, but for his two
+companions as well.</p>
+
+<p>“You seem irresolute,” Englebreth observed. “And no wonder, Cole. For
+once in your life, you are absolutely helpless. You have been entirely
+too meddlesome, and people who meddle in others’ affairs usually get
+into trouble. Listen!”</p>
+
+<p>Cole listened. A faint smile played about Englebreth’s lips as the
+whirring of machinery sounded clearly in the surrounding silence.</p>
+
+<p>“Know what it means, Cole. It means gold! Gold!” His lips seemed to
+caress the word. “Millions and millions and millions, Cole. After you
+are gone we shall be turning out gold in unlimited quantities. I and my
+associates shall be the richest men in the world. And you, poor worm,
+who thought you could stop us, will be reduced to a few grains of dust.”</p>
+
+<p>“Sure of that?” demanded Cole.</p>
+
+<p>His tone, clear and confident, seemed to impress the invalid.</p>
+
+<p>“Why do you ask? Surely you don’t expect to escape from your present
+predicament. As it happens, all the members of my organization are here
+to-night. A touch of my finger will summon twenty men to my assistance,
+if necessary.”</p>
+
+<p>He scanned Cole’s face for a sign of fear, but none came. The other’s
+coolness seemed to nettle him.</p>
+
+<p>“So the gang is all here,” said Cole carelessly. “That means, of
+course, that Doctor Ballinger is included?”</p>
+
+<p><span class="pagenum" id="Page_294">294</span></p>
+
+<p>“Naturally. An excellent man, Ballinger. He has a practical mind, and
+he knows on which side his bread is buttered. Why do you ask?”</p>
+
+<p>“I am glad he is here,” said Cole. “I wouldn’t want him to get away
+from me, you know.”</p>
+
+<p>The invalid leaned out of the chair and stared. “Get away?” he echoed.
+“What do you mean?”</p>
+
+<p>“I have a particular score to settle with Ballinger,” said Cole calmly.
+“Naturally I want him present when I hand you and your gang over to the
+police.”</p>
+
+<p>“When you——” Englebreth was utterly astounded. “If you think this is a
+joking matter——”</p>
+
+<p>“I was never more serious in my life, Englebreth. Before daybreak I
+expect to hand every mother’s son of you over to the authorities.”</p>
+
+<p>Englebreth stared for a moment longer; then he laughed hoarsely. Cole
+could see that his cool insolence had exerted the intended moral
+effect. The invalid, though the advantage was all on his side, felt
+just a trifle ill at ease. Cole’s demeanor was well calculated to
+suggest that a surprise of some sort was forthcoming. Englebreth would
+not have been human if he had failed to be impressed by the airy
+assurance of one whom he thought wholly at his mercy.</p>
+
+<p>Finally he shrugged. “You must be mad,” he muttered. Then he faced
+Latham, who stood beside the chair in which Miss Brownell sat. “I have
+something to say to you, doctor. You did us a service once, and that is
+something I never forget. If you will——”</p>
+
+<p>“Save your breath,” interrupted Latham contemptuously. <span class="pagenum" id="Page_295">295</span>“For a time, a
+little while ago, I was tempted to enter into negotiations with you,
+but Miss Brownell wouldn’t hear of it. What is a mere man to do when a
+woman sets her foot down?”</p>
+
+<p>“Your flippancy is ill-timed,” said Englebreth austerely.</p>
+
+<p>“Hasn’t one a right to joke at one’s own funeral?”</p>
+
+<p>“We shall see.” Englebreth’s lips tightened ominously. “You know what
+we want from you, doctor. Only a formula that by right belongs to us,
+since you worked it out while you were a member of this organization.
+Produce it, and I promise to be lenient with you and Miss Brownell.
+Unless my senses deceive me”—and Englebreth smiled craftily—“you are
+very anxious that nothing unpleasant shall happen to her.”</p>
+
+<p>Latham hesitated, impressed by the cruel smile on the invalid’s lips,
+and the girl answered in his place.</p>
+
+<p>“Doctor Latham’s answer is <i>no</i>,” she declared emphatically.</p>
+
+<p>Englebreth regarded her curiously, with an odd mingling of admiration
+and malice. “You are a stubborn young person,” he muttered. “For the
+last time, doctor, I ask you if you will consent to my terms.”</p>
+
+<p>Again it was Miss Brownell who answered. “Doctor Latham refuses,” she
+declared. “He knows that your promises are worthless, that you intend
+to kill us regardless of whether or not he grants your request. I don’t
+think there is anything further to be said.”</p>
+
+<p><span class="pagenum" id="Page_296">296</span></p>
+
+<p>“No?” Englebreth’s thin fingers seemed to tighten around the pistol.
+“Perhaps I can convince you——”</p>
+
+<p>He stopped short. A squeallike cry of astonishment escaped him, for
+Cole had just done a very unexpected thing. It was so unexpected,
+in fact, that it seemed like the act of a person whose reason was
+tottering. With arms folded across his chest he had casually approached
+the chair in which Miss Brownell sat. For a time he had seemed absorbed
+in deep thought, but all the while he had been scheming how he might
+divert Englebreth’s attention, even if only for a moment, from the
+menacing pistol in his hand. Anything of a startling nature, the more
+bizarre and ludicrous the better, would serve his purpose. Now he
+turned suddenly and gave the girl a resounding slap on the cheek. He
+followed it up with another, then with a third.</p>
+
+<p>A spell seemed to fall over the gathering. They had witnessed an act,
+in itself trivial and ridiculous, that staggered their reason by its
+sheer fatuity. For a measured moment their minds were at a standstill.
+That was exactly what Cole had intended, and a moment was all he
+needed. He had acted on a fugitive inspiration at a time when all
+seemed lost, when a move of a more rational nature would only have
+hastened the inevitable.</p>
+
+<p>The resounding smack of the third blow had scarcely drifted out on the
+silence when he leaped at the invalid’s chair. In an instant, while the
+minds of Englebreth and the two guards at the door were still dazed
+from contemplation of a <span class="pagenum" id="Page_297">297</span>thing so bizarre, he had snatched the pistol
+from the cripple’s hand. A moment later he was crouching low behind
+Englebreth’s chair, pressing the muzzle of the weapon against his back.</p>
+
+<p>He thrilled inwardly. Once more his mind had triumphed over a critical
+situation. The other time had been when he faced Professor Carmody in
+the Bureau of Civic Research. The professor had been thrown off his
+mental base by a trick just as simple and effective.</p>
+
+<p>“Tell your men to drop their weapons,” he commanded, the muzzle of the
+pistol prodding Englebreth’s back. “I’ll give you exactly ten seconds.
+Unless you obey, you will be a dead man.”</p>
+
+<p>Englebreth squirmed in the chair, evidently in a state of great terror.
+In a few minutes his agile mind might reassert itself, but just now
+he was merely a shivering wreck. His trembling hand went up and made
+a signal to his men just as Cole was about to call time. Habitually
+obedient to the master will, the men at the door dropped their pistols.</p>
+
+<p>Cole rose from his crouching position behind Englebreth’s chair. Latham
+and the girl stared at him bewilderedly, the latter moving her hand
+dazedly over the cheek that Cole had struck, both seemingly unable to
+realize as yet what had happened. Englebreth was breathing raspingly.
+The two guards at the door gazed dully at the erect figure behind the
+invalid’s chair.</p>
+
+<p>“Pick up those pistols, Latham,” said Cole quietly. “Pardon my
+rudeness, Miss Brownell. It was necessary.”</p>
+
+<p>She smiled uncertainly, evidently beginning to understand. <span class="pagenum" id="Page_298">298</span>It was
+several moments before the physician could shake off his stupefaction.
+He moved haltingly over the floor and dazedly took possession of the
+pistols.</p>
+
+<p>“It was magnificent, Mr. Cole!” murmured the girl, at last grasping the
+psychological stratagem by which Cole had reversed the situation.</p>
+
+<p>“But if I hadn’t seen it happen, I would have sworn it couldn’t be
+done,” said Latham.</p>
+
+<p>Cole’s face was grave. His ruse had only averted their immediate
+danger. Any moment other members of the organization might pour into
+the room, crushing them by superior numbers. Every second counted now.
+Holding the pistol in one hand, Cole drew the telephone to him and
+spoke a number in the transmitter. Only a few words would be needed to
+make Carlin understand the situation, and within an hour reinforcements
+would arrive. He wondered, as he waited for his connection, if they
+could hold out until then. Impatiently he jigged the hook, muttering
+heartfelt imprecations upon the state of the rural telephone service,
+and then, in a twinkling, something happened.</p>
+
+<p>He saw the cripple’s weazened hand move stealthily along the side of
+the desk, became conscious that a heretofore unnoticed door had burst
+open behind him, heard the girl’s quick, startled cry, saw the light
+blotted out as if a pall had suddenly dropped over the little room,
+felt a stinging blow at the back of the head, and, with Englebreth’s
+diabolic chuckles dinning in his ears, fell to the floor.</p>

+</div>
+
+<p class="drop-cap">“GOLD! Gold!” The vibrant murmurs, edged with a triumphant and sinister
+note, echoed in Cole’s ears as he opened his eyes. The house was
+shivering with a slow, rhythmic tremor, a throbbing pulsation that
+instantly began to pierce the fog in his mind.</p>
+
+<p>From his recumbent position on the floor he struggled to a sitting
+posture. Lifting his head, he listened to the grimly exultant pæan
+rising from the bowels of the earth.</p>
+
+<p>“Feeling better?” asked a voice which he vaguely recognized at Doctor
+Latham’s.</p>
+
+<p>Cole did not answer. The subterranean vibrations seemed to cast a spell
+over his awakening senses.</p>
+
+<p>“Hear it?” he asked at length.</p>
+
+<p>“Hear what?”</p>
+
+<p>“This infernal hymn of gold. It will drive me crazy if I have to listen
+to it much longer.”</p>
+
+<p>“Then don’t listen. Know what time it is?”</p>
+
+<p>Cole shook his head as if to indicate that the matter was of absolutely
+no importance.</p>
+
+<p>“Precisely twelve o’clock,” said the doctor, and Cole heard something
+resembling the snapping of a watch lid. “You have been unconscious for
+something like ten hours. That was the second knock-out in a night,
+Cole. Why can’t these scoundrels show a little versatility?”</p>
+
+<p>“What happened?” asked Cole dully.</p>
+
+<p><span class="pagenum" id="Page_300">300</span></p>
+
+<p>“As if that mattered now! Englebreth gave a signal of some sort, and
+the next thing I knew about half a dozen of his hired thugs swooped
+down on us. My recollections cease at that point.”</p>
+
+<p>“Where are we?”</p>
+
+<p>“In the same room we occupied last night, before we were ushered into
+Englebreth’s august presence. The windows are just as tightly shuttered
+as they were then, and the door is just as impregnable. I wonder if
+these hounds mean to let us starve to death.”</p>
+
+<p>Cole looked about him. An electric light was burning dimly over their
+heads. Through a narrow rift in one of the shutters came a shaft of
+sunlight, gilding the dust in the stale air.</p>
+
+<p>“Where is Miss Brownell?” he asked abruptly.</p>
+
+<p>“Wish I knew,” muttered the doctor. Of a sudden all the levity had died
+out of his voice. “You and I were alone in this room when I came to. If
+these rats harm a single hair on her head——” The threat died unfinished
+in a groan.</p>
+
+<p>With difficulty Cole rose to his feet and leaned against the wall.</p>
+
+<p>“I don’t seem to remember just where we were at,” he mumbled.</p>
+
+<p>“You gave Miss Brownell a slap on the cheek,” the doctor reminded him.
+“It was a brilliant idea, Cole.”</p>
+
+<p>“So it was—but it failed, as I remember,” Cole muttered grimly. “What
+was the situation just before that?”</p>
+
+<p>“Englebreth was doing his level best to bluff me into revealing the
+formula of the mythical seventh <span class="pagenum" id="Page_301">301</span>ingredient. Perhaps you remember his
+sportsman-like proposition. I was to give him the formula in return for
+my life.”</p>
+
+<p>“He would promptly kill you the moment you surrendered the formula,”
+Cole pointed out.</p>
+
+<p>“Without a doubt. He would kill all three of us. But, as it happens, I
+can’t give him the formula, because it doesn’t exist.”</p>
+
+<p>“But as long as he thinks it does, we are holding a trump card in
+reserve,” said Cole, regaining his grip on the tangled threads of the
+situation.</p>
+
+<p>“If only we knew how to use it!”</p>
+
+<p>“We’ll find a way,” said Cole confidently, dragging himself to a chair
+at one side of the room. “Anything about your person that could be used
+as a weapon in an emergency?”</p>
+
+<p>“Not a thing. I am plucked clean.”</p>
+
+<p>“So am I,” said Cole after a hasty survey of his pockets. “No, here is
+a stick pin. They seem to have overlooked that. The pin is long and
+sharp. You could pierce a person’s jugular vein with an implement of
+this kind, couldn’t you, doctor?”</p>
+
+<p>“If you knew exactly where to strike.”</p>
+
+<p>“You do, of course, being a doctor. As a weapon it would be useless in
+my hand, so I will transfer it to you. I suggest you conceal it under
+the lapel of your coat.”</p>
+
+<p>Puzzled, Latham took the ornament and did as Cole had directed. As he
+hid it under his lapel, he seemed inclined to ask a question, but Cole
+forestalled him.</p>
+
+<p><span class="pagenum" id="Page_302">302</span></p>
+
+<p>“I think some one is coming,” he remarked in an undertone.</p>
+
+<p>Latham, listening, heard the sounds which Cole’s keener ears had caught
+first. Folding his arms across his chest, he struck a carefree pose and
+looked toward the door. It opened, and two armed stalwarts walked in.
+They were followed by Englebreth in his wheel chair. Two more guards,
+also armed, brought up the rear. With a cautious look to all sides,
+the invalid trundled his wheel chair into the center of the room. The
+barrel of a small automatic gleamed viciously in the electric light.</p>
+
+<p>“How do you do, gentlemen?” he said in tones of mock geniality. “Wish
+I could offer you some breakfast, but it has been my experience that
+people are always more reasonable when their stomachs are empty. I have
+come to renew our discussion where we left off last night.” He fixed
+his bleak and very alert eyes on Doctor Latham.</p>
+
+<p>“Better save your breath,” suggested the physician. “You may need it
+before we are through with you.”</p>
+
+<p>Englebreth smiled serenely. “I don’t blame you, doctor, for trying
+to bolster up your courage. People usually resort to false bravado
+when they are hopelessly situated. Our friend Cole enacted quite a
+spectacular scene last night, but he will hardly try anything like that
+again. He has learned his lesson. Well, doctor, are you ready to oblige
+us?”</p>
+
+<p>“If you will drop that automatic, I’ll oblige you with a smash on the
+jaw,” said the physician in unprofessional but impressive language.</p>
+
+<p><span class="pagenum" id="Page_303">303</span></p>
+
+<p>“Still stubborn, I see.” His smile took on a sinister quality. “I
+suppose you are wondering what has become of Miss Brownell?”</p>
+
+<p>The doctor bit his lip, but his gaze did not waver. “If anything
+happens to Miss Brownell,” he muttered hotly, “I’ll choke you to death
+with my bare hands.”</p>
+
+<p>“Save your threats, doctor. They don’t interest me in the least. As
+yet nothing whatever has happened to Miss Brownell, but something will
+unless you adopt a more reasonable attitude. I warn you that it will be
+something decidedly unpleasant.” He turned slightly in the chair and
+addressed one of his bodyguards. “Ask Doctor Ballinger to step in here.”</p>
+
+<p>The man nodded and left the room. A questioning glance passed between
+Latham and Cole, the former looking as if a dread suspicion had
+suddenly occurred to him. In a few moments the messenger returned with
+Ballinger. The physician strode in with a jaunty air and saluted Cole
+and Latham with exaggerated politeness.</p>
+
+<p>“Ah, Ballinger,” said the cripple in an undertone, yet loud enough for
+the two prisoners to hear, “I just wished to make certain that you have
+made all necessary arrangements for the—ahem—experiment we discussed
+last night.”</p>
+
+<p>Cole, casting a sidelong glance at Latham, saw him stiffen suddenly. A
+film of pallor spread above the bearded portion of his face.</p>
+
+<p>“Yes, everything is ready,” announced Ballinger.</p>
+
+<p>“The instruments came?”</p>
+
+<p>“Just a little while ago.”</p>
+
+<p><span class="pagenum" id="Page_304">304</span></p>
+
+<p>“And the ether?”</p>
+
+<p>“It is here too.”</p>
+
+<p>“Good, Ballinger. Be ready to proceed the moment you hear from me.” He
+waved a withered hand in dismissal.</p>
+
+<p>Ballinger, an inscrutable smile playing about his lips, left the room.
+An intense silence followed. The cripple’s gelid gaze moved from Latham
+to Cole, and then back to Latham.</p>
+
+<p>“You understood?” he asked.</p>
+
+<p>Neither man answered. A harrowing suspicion seemed to have come over
+both of them. Latham looked as if his powerful body was racked by an
+agonizing dread.</p>
+
+<p>“Ballinger is a very clever man,” murmured the invalid. “You know
+what happened to Malcolm Reeves.” He paused, looked stonily at Doctor
+Latham, as if waiting for his last words to produce their utmost
+effect. “The same thing,” he added slowly, measuring each word, “will
+happen to Miss Brownell unless you change your mind, Latham.”</p>
+
+<p>A cry of mingled horror, loathing and hate broke from Latham’s
+compressed lips. He sprang toward the cripple, hand raised as if to
+strike, but in an instant two of the bodyguards intervened.</p>
+
+<p>“Glad we understand each other, Latham,” said the cripple calmly. “The
+operation will start in fifteen minutes unless you submit to my terms.”</p>
+
+<p>Latham stood speechless. The only sound heard in the room was a great
+sigh.</p>
+
+<p>“Don’t like the idea, eh, Latham?” the invalid went on in smooth,
+dulcet tones. “The spectacle <span class="pagenum" id="Page_305">305</span>of Miss Brownell reduced to a gibbering
+lunatic is a little too much for your imagination to dwell on. You have
+a vivid recollection of what happened to Reeves.”</p>
+
+<p>A dull, hoarse groan sounded in the physician’s chest. Cole, watching
+him, thought he was about to give way under an overwhelming strain.</p>
+
+<p>“You’re mistaken, Englebreth,” he managed to say. “There is no such
+thing as the seventh ingredient. I let you go on thinking so because——”</p>
+
+<p>Englebreth interrupted with a wave of his hand. “I expected you to
+say that. It would be your logical evasion. You can’t deceive me with
+such nonsense. Only last night you discussed the possibilities of the
+seventh ingredient with Professor Carmody. As he explained it to me,
+it’s a sort of electronic reaction. Not being a scientific man, I don’t
+understand what that means, but it doesn’t matter. I have the utmost
+respect for your scientific achievements, doctor. Will you give us the
+formula?”</p>
+
+<p>Latham fumbled in vain for a convincing argument. His advantage had not
+only slipped away from him, but it had become a deadly boomerang in
+Englebreth’s hand.</p>
+
+<p>“I swear I am telling you the truth!” he cried brokenly.</p>
+
+<p>A cold smile curled the cripple’s lips. “Such childish subterfuge
+doesn’t go with me,” he said contemptuously. “Either you give me the
+formula instantly, or Miss Brownell will be a lunatic inside of an
+hour. Take your choice.”</p>
+
+<p>He leaned back in the chair, slowly and playfully <span class="pagenum" id="Page_306">306</span>twisting the
+automatic in his hand. Cole stepped forward.</p>
+
+<p>“Latham has told you the truth,” he declared. “The seventh ingredient
+never existed outside of his imagination.”</p>
+
+<p>Englebreth shrugged with an air of utter incredulity. Cole could see
+that there was no way of disturbing his firmly rooted belief. And he
+knew that, even if the seventh ingredient had been a reality, Latham’s
+submission would not have altered their situation.</p>
+
+<p>Englebreth looked at his watch, then summoned one of his bodyguards and
+whispered something in his ear. The man left the room. The slamming
+of the door sounded like a death knell in the tense silence. Latham’s
+chest heaved in a frenzy of suppressed emotions. Minutes passed, and
+then hurried footsteps sounded overhead, accompanied by the sound of
+a resisting body being dragged over the floor. Latham, with a wild
+look in his face, started forward, but one of the guards shoved him
+back. Breathing fast and raspingly he swayed unsteadily on his feet.
+Of a sudden he gave a violent start, then stood as if frozen into
+immobility. From the room above came a long cry of terror, uttered in a
+woman’s voice.</p>
+
+<p>Latham’s bulging eyes stared upward. There was a look of insanity in
+his face.</p>
+
+<p>“Stop it!” he cried hoarsely. “For God’s sake——”</p>
+
+<p>Another cry, more poignant than the others, shrilled through the house.</p>
+
+<p>“Stop it—you fiend!” cried Latham.</p>
+
+<p><span class="pagenum" id="Page_307">307</span></p>
+
+<p>“I will, on one condition,” said Englebreth calmly. “There is still
+time. They are only making preparations upstairs. She won’t cry when
+the real business begins.”</p>
+
+<p>Latham’s hand went to his eyes as if to exclude a hideous vision.</p>
+
+<p>“Careful, Englebreth!” said Cole evenly. “If you go too far, Latham may
+lose his mind.”</p>
+
+<p>“And if he does, what then?” demanded the cripple jeeringly.</p>
+
+<p>“A number of things may happen.” Cole gave the physician a level,
+significant glance. “For instance, Latham may take it into his head to
+kill himself.”</p>
+
+<p>The physician’s head went up. His hands left his face. A look of
+dawning comprehension crept into his features. He turned his head and
+for an instant his eyes met Cole’s, reading a message there.</p>
+
+<p>“Kill himself?” echoed the cripple, astonished. “What rot, Cole! How
+would he do it, and why?”</p>
+
+<p>“Ask him,” said Cole with a careless gesture. “I can only point out to
+you that if he kills himself the secret of the seventh ingredient dies
+with him. Look! He is——”</p>
+
+<p>He simulated a cry of astonishment and horror. Latham, quickly
+interpreting the message he had read in Cole’s eyes, had snatched the
+stick pin from under the lapel of his coat.</p>
+
+<p>“Watch me, Englebreth,” he declared in a voice that had suddenly
+retrieved all its lost vigor. “Even a stick pin makes quite a
+formidable weapon if it’s pointed in the right direction. I am pointing
+this one straight at my jugular vein. The moment <span class="pagenum" id="Page_308">308</span>anybody in this room
+makes a move, I drive it in. Where will your seventh ingredient be
+then, Englebreth?”</p>
+
+<p>The cripple stared at him in speechless bafflement. He raised a hand,
+but it fell limply to his side.</p>
+
+<p>“You—you’re crazy!” he stuttered.</p>
+
+<p>“Maybe,” said Latham coolly.</p>
+
+<p>“Or else you are only bluffing.” There was a trace of doubt in
+Englebreth’s tones.</p>
+
+<p>“Why should I be bluffing? I would rather kill myself than be killed by
+your bunch of hyenas. I know you meant to kill me, anyway, Englebreth.
+One thing is certain. Unless you stop the preparations upstairs within
+the next sixty seconds, your last hope of obtaining that formula will
+be gone. You can’t get anything out of a dead man.”</p>
+
+<p>Englebreth strained forward in his chair, staring into the physician’s
+grim, determined face.</p>
+
+<p>“He means what he says,” Cole declared, smiling despite the tension of
+the moment. “You will have to act quickly, Englebreth.”</p>
+
+<p>The cripple considered a moment longer, then bawled an order to one
+of the men at the door. The fellow hurried away, and in a moment
+they heard him scurrying up the stairs. An exchange of words sounded
+overhead, then all was quiet.</p>
+
+<p>Englebreth made an impatient gesture with his hand. The bodyguard
+closed in around him, and with petulant motions he wheeled himself out
+of the room. At the door he turned his head for a moment, and a little
+chill rippled down Cole’s back as he saw the cold, malignant look in
+the cripple’s eye.</p>

+<div class="subheadc">THE WAY OUT</div>
+</div>
+
+<p class="drop-cap">DOCTOR LATHAM stroked his beard thoughtfully as the door closed behind
+the invalid and his retinue. “It worked like magic,” he remarked.</p>
+
+<p>“It worked,” Cole amplified, “because we were dealing with a logical
+mind, one that deals mainly with reason and fails to consider the human
+equation. We know that Englebreth means to kill us in the end, and he
+knows that we know it. That being the case, it wasn’t hard for him
+to put himself in your place a little while ago. He would have done
+what you threatened to do, because it was the logical move under the
+circumstances. I wonder what deviltry Englebreth will be planning next.”</p>
+
+<p>“A seven-course dinner, I hope,” said the doctor wistfully. “I’m
+famished.”</p>
+
+<p>Cole regarded him musingly, marveling at the resiliency of his spirits.
+Latham appeared to have shaken off all external cares the moment he saw
+that Miss Brownell was no longer in immediate danger.</p>
+
+<p>“You might as well restrain your appetite, doctor,” he murmured. “You
+heard what Englebreth said, that a man is most amenable to argument
+when he is hungry. At any rate, it is worth something to know that he
+doesn’t want you to die just yet. He showed that plainly when you made
+that monumental bluff with the stick pin. I saw him turn white as a
+ghost.”</p>
+
+<p>“Thanks to the seventh ingredient,” said Latham <span class="pagenum" id="Page_310">310</span>with a chuckle. “It’s
+the best kind of life insurance, but I fear it won’t last long. Any
+more tricks in your repertory, Cole?”</p>
+
+<p>“One more, I think.” Cole glanced toward the shadowy corner where he
+had stood during Englebreth’s presence in the room. “I understand,” he
+went on casually, “that Dutchess Point was once a very gay place.”</p>
+
+<p>“If so, its gayety hasn’t improved with age.”</p>
+
+<p>Cole ignored his flippancy. “I’ve been told it was once a notorious
+gambling resort. Places of that kind are usually equipped with
+contrivances for making hasty exits—trapdoors, sliding panels and that
+sort of thing.”</p>
+
+<p>Latham raised his brows. “What are you getting at?”</p>
+
+<p>But Cole seemed in no hurry to approach his subject. “Ever notice,
+Latham, that many people find it very hard to remain motionless when
+they are in a state of deep mental concentration? Physical movement
+of some sort seems a necessary relief from mental effort. One man I
+know is always plucking at his watch chain when he is absorbed in some
+mental task. Another taps his desk with a pencil. My own favorite
+diversion on such occasions is to beat a tattoo with my knuckles.”</p>
+
+<p>“Highly interesting,” remarked Latham, “but I fail to see the point. It
+is either very shallow or very deep.”</p>
+
+<p>“Neither, Latham. A little while ago, while you were enacting that
+highly dramatic scene for Englebreth’s benefit, I stood back there in
+the corner, with my hands behind my back, tapping the wall <span class="pagenum" id="Page_311">311</span>with my
+knuckles. No one noticed me, for you held the attention of everybody
+in the room. I didn’t realize what I was doing myself until suddenly I
+became aware that my knuckles were producing a hollow sound.”</p>
+
+<p>Doctor Latham gasped. “You mean that——”</p>
+
+<p>“We shall see,” said Cole; and in an instant he was back in the corner,
+crouching low while his knuckles hammered the wall, each tap producing
+a dull, hollow sound. The doctor, visibly excited, stood behind him,
+watching every move he made. Cole continued the tapping until he had
+determined the boundaries of the hollow space, extending about five
+feet from the corner, and then he got down on his knees and ran his
+hands along the beveled joint between wall and floor. A little cry of
+elation escaped him as his fingers encountered a small protuberance.
+Almost instantly a portion of the wall turned back as if swinging on a
+central pivot. In front of them extended a long, dark hall.</p>
+
+<p>“Great!” exclaimed Latham, his voice shaking a little. “You deserve a
+harp and a halo, Cole. Now let’s make the hasty exit you spoke of.”</p>
+
+<p>He pressed forward, but Cole pulled him back. “I don’t want a harp
+and a halo just yet,” he declared, “and that’s why we are going to
+stay in this room a while longer. You forget that it’s still broad
+daylight outside. If we went out now, we would doubtless run into one
+of Englebreth’s sluggers. We must wait till dark.”</p>
+
+<p>Latham groaned as Cole closed the opening. He glanced at his watch.
+“Only half past three. That means a wait of several hours.”</p>
+
+<p><span class="pagenum" id="Page_312">312</span></p>
+
+<p>“I know. That will give us ample time to lay our plans. Don’t forget
+that we are both unarmed, and that we’ll cut a sorry figure if we
+should be caught. We don’t want to waste the only advantage we have.”</p>
+
+<p>“You are right, of course,” admitted the doctor. “What do you suggest?”</p>
+
+<p>Cole reflected. “It isn’t likely Englebreth knows anything about the
+hidden exit. If he did, he would have chosen a different cell for us.
+We’ll treat him to a little surprise after dark, Latham. Its exact
+nature will be determined by whatever developments come along in the
+meantime.”</p>
+
+<p>“Wish they would hurry,” mumbled the doctor, all impatience now that
+a way out had been found. He sat down, lighted a cigarette, and made
+ostentatious efforts to compose himself for a wait. An hour dragged
+by. The beam of light coming through the narrow rift in the shutter
+grew thin and pale. Another hour passed, and it disappeared altogether.
+Latham got up and began pacing the floor with long, lunging strides.
+For a long time not a word had been uttered between the two men.</p>
+
+<p>“Isn’t it about time to make a move?” asked Latham suddenly.</p>
+
+<p>Cole started. The subterranean pulsations, sounding clear and exultant
+in the stillness, had cast a spell over his senses. Now he looked at
+his watch in the light of the electric bulb overhead.</p>
+
+<p>“Better wait another hour,” he suggested.</p>
+
+<p>Doctor Latham swore under his breath, then lighted another cigarette.</p>
+
+<p>“Queer we haven’t heard from Englebreth,” Cole <span class="pagenum" id="Page_313">313</span>remarked. “I expected
+another call from him before dark.”</p>
+
+<p>“He is probably meditating over his next move. I imagine he is planning
+a very brilliant stroke. But we’ll checkmate him, eh, Cole?”</p>
+
+<p>Latham’s impatience was beginning to communicate itself to Cole. He
+took his watch from his pocket, and in the same instant a noise sounded
+outside the door. In a moment it opened, and two huskies, with leveled
+automatics, appeared in the room.</p>
+
+<p>“Miss Brownell wants you,” announced one of them, addressing Doctor
+Latham.</p>
+
+<p>The physician, evidently in a quandary, looked questioningly at Cole.
+For only a moment Cole hesitated. Doubtless the summons meant that
+Englebreth was trying a new mode of attack and that the reference to
+Miss Brownell was only a subterfuge.</p>
+
+<p>Cole nodded in response to the physician’s unspoken question. “If Miss
+Brownell wants you, you must go to her,” he declared, conscious that
+one of the guards was watching him intently. In an undertone he added:
+“If you get into a pinch, keep stalling till I show up.”</p>
+
+<p>Latham nodded and walked out, accompanied by the two gangsters. Cole
+watched him until the door closed behind him.</p>
+
+<p>“Wonder what Englebreth is up to this time,” he muttered; and then,
+moving quickly, he stepped into the corner and, opening the hidden
+door, stepped out into the dark hall beyond.</p>
+
+<hr class="chap x-ebookmaker-drop">
+<div class="chapter">
+<span class="pagenum" id="Page_314">314</span>
+<h2 id="chap_XXVIII">CHAPTER XXVIII</h2>
+<div class="subheadc">THE ENEMY STRIKES</div>
+</div>
+
+<p class="drop-cap">SILENT as a shadow, Cole hurried down the hall, which seemed to extend
+endlessly in an undeviating direction. Believing it had once been used
+as an emergency exit he supposed it would eventually lead into the
+open. He had made no plans beyond the immediate present, but it was
+his intention to join Doctor Latham as soon as possible and, taking
+advantage of the sensation his unexpected appearance would create,
+make the most of his opportunity. Beyond doubt the physician was in
+desperate danger. The murderous glance Englebreth had thrown over his
+shoulder as he left them a few hours ago had left an ominous imprint on
+Cole’s mind.</p>
+
+<p>Soon he brought up against an obstruction, apparently a blank stretch
+of wall. He fumbled with his hands along the surface expecting to find
+a contrivance similar to the one at the other end of the wall. Soon
+his fingers encountered the little knob at the bottom which told him
+his surmise had been correct. Cautiously he pressed outward and the
+obstruction gave. A breath of cool night air fanned his face as he
+stepped out.</p>
+
+<p>Hugging close to the wall he looked about him. Evidently he was in the
+rear of the house, in a wide recess formed by two projecting wings.
+Above him and to the sides were several lighted windows, <span class="pagenum" id="Page_315">315</span>while ahead
+of him was a sloping, rock-strewn stretch of landscape. Carefully
+picking his way, he stepped along the nearest wall, all his senses
+on the alert against an interruption. He reached the corner, looked
+around the edge of the wall, and then drew back. A stalwart individual,
+evidently one of Englebreth’s lookouts, was coming toward him.</p>
+
+<p>Cole shrank back against the wall, waited until the man rounded the
+corner, then swung out with his right hand and landed a smashing blow
+on the fellow’s jaw. Without a sound the sentry dropped to the ground,
+and Cole dragged him into the shadows along the wall. It took him but a
+few moments to undo the man’s shoe laces and secure his hands and feet.
+Next he ripped out the lining from his coat, folded it into a narrow
+strip, and firmly applied it as a gag. Last of all he extracted an
+automatic from the unconscious man’s hip pocket.</p>
+
+<p>“I’m in luck so far,” he told himself, making certain that the weapon
+was loaded before he continued his interrupted progress. He breathed
+more easily now, for the possession of a firearm had a soothing effect
+on his nerves. He crawled forward along the wall, exercising infinite
+care, until he reached a window in the wing. It was dark, and no sound
+came from within, signifying that this part of the building was not
+used by the gang. He placed his elbow against the pane, pressing firmly
+until the glass cracked. Dislodging several of the splinters, he pushed
+a hand through the opening and released the catch. In a moment he was
+inside and began to pick his way cautiously across the floor. At the
+farther side he opened a door, traversed another <span class="pagenum" id="Page_316">316</span>dark and deserted
+room, then still another. Soon he found himself in a hall, and after
+a glance up and down its length selected a door at random. The moment
+he stepped inside voices reached his ears. Along the side, diagonally
+across the floor from where he stood, a narrow streak of light showed
+the location of the door.</p>
+
+<p>He tiptoed across the floor, placed his hand on the knob, turned it
+carefully, and opened the door an infinitesimal crack. In an instant
+he recognized the room. It was the office that had been the scene of
+his short-lived triumph the night before. Englebreth was seated at
+the desk, occupying the same wheel chair in which he had sat while
+witnessing Cole’s abortive ruse. The door before which Cole now stood
+was the one that had so abruptly opened while he was on the point of
+telephoning Carlin. He was vaguely aware that the scene had changed
+since last night, but he had no time to observe details. His attention
+was instantly engrossed by the little drama taking place before his
+eyes.</p>
+
+<p>On a cot placed along the farther side of the room lay Latham, and,
+save for an occasional turn of the head, he lay so still that Cole,
+although he could not see distinctly, guessed that he must be strapped
+to the cot. Over him, bending slightly, with a wicked smile playing
+about his bearded lips, stood Doctor Ballinger, and in his hand was a
+small object which Cole could not distinguish. The only other occupants
+of the room were Englebreth and two of the stalwart bodyguards who
+always seemed to be hovering about him.</p>
+
+<p><span class="pagenum" id="Page_317">317</span></p>
+
+<p>“Yes, it was clever, Latham,” the cripple was saying. “You played your
+cards just right. Whether you were serious or whether you were bluffing
+is beside the point. Your death would have been ill-timed from my point
+of view. I don’t think you are afraid to die, Latham. There is one
+thing you are afraid of, however.”</p>
+
+<p>He stopped. For several moments the room was very still. Ballinger,
+straightening his back, looked meditatively at the object in his hand,
+which, as Cole now perceived, was a small bottle.</p>
+
+<p>“That one thing is blindness, Latham,” added the cripple impressively.
+“Tell him, Ballinger.”</p>
+
+<p>Ballinger held the vial before the recumbent man’s eyes. “One small
+particle of this fluid dropped into each of your eyes will blind you
+for life,” he announced. “Not a pleasant thing to contemplate, eh,
+Latham?”</p>
+
+<p>Cole started as he saw the diabolical form of persuasion that was being
+employed by the conspirators to make Latham reveal what he was supposed
+to know. It was a threat far more hideous than death itself. He saw
+Latham’s chest heave upward as he strained against the fetters that
+held him to the cot.</p>
+
+<p>“What do you say, Latham?” asked the cripple, bending slightly out of
+his chair.</p>
+
+<p>“I’ll say that you and Ballinger are a pair of scurvy blackguards,” was
+the physician’s retort. “I take solemn oath that I will send each of
+you to jail with a black eye.”</p>
+
+<p>Ballinger laughed derisively.</p>
+
+<p>“Still stubborn, I see,” Englebreth remarked. “I <span class="pagenum" id="Page_318">318</span>am warning you for
+the last time, Latham. If you think Cole can come to your rescue, you
+are mistaken. Between you and me, that infernal meddler will never
+leave Dutchess Point alive. With you it is different. You can make
+yourself useful to us, and that is why I am offering you terms. But you
+must decide quickly.”</p>
+
+<p>“Go to blazes!” said Latham, but there was a catch in his voice,
+scarcely audible even to Cole’s keen ears, which told that his courage
+was faltering.</p>
+
+<p>“He thinks we are bluffing, Ballinger,” said Englebreth. “We must
+convince him that we are serious. Drop a little of the fluid into his
+left eye. The result will prove to him that we mean business.”</p>
+
+<p>A muffled groan came from the man on the cot. Ballinger stepped closer
+to the light, uncorked the little vial, cautiously inserted a small
+syringe through the neck, his brows contracting as he pumped the
+requisite amount of fluid into the glass tube. Now he set the bottle
+down, replaced the cork, and with the syringe in his hand turned again
+toward the man on the cot. A faint grin hovered about his bearded lips,
+but he had taken only a step in the direction of the cot when a sharp
+command rang out:</p>
+
+<p>“Stop, Ballinger!”</p>
+
+<p>As he spoke, Cole sprang forward and landed a vigorous blow with
+his automatic on the right hand of the guard standing nearest to
+Englebreth. A pistol dropped from the man’s limp fingers, and with an
+instantaneous movement Cole picked it up.</p>
+
+<p><span class="pagenum" id="Page_319">319</span></p>
+
+<p>Ballinger jerked up his head, then stopped dead in his tracks, facing
+the cot. The cripple whirled round in his swivel chair, a look of utter
+consternation flooding his white face as he saw Cole, standing calmly
+a foot away, a leveled automatic in each hand. The second guard leaped
+forward, but in a moment Cole had him covered.</p>
+
+<p>“Drop that gun!” he ordered, making an ominous gesture with one of his
+pistols. “This instant!”</p>
+
+<p>The man’s jaw sagged, and the weapon dropped from his hand. Englebreth,
+sitting hunched and shuddering in his chair, stared at the intruder as
+if he were seeing a specter.</p>
+
+<p>“You!” he exclaimed in a thin, rasping voice. “You——”</p>
+
+<p>Cole ignored him. His eyes gleamed like points of polished steel.
+“Ballinger,” he said in a very calm voice, “I’d rather put a bullet
+through your black heart, but I’m going to give you one chance for your
+life. See how quickly you can cut Doctor Latham loose. A little speed
+may save your life.”</p>
+
+<p>The syringe fell from Ballinger’s trembling fingers. For a moment he
+hesitated, then a knife appeared in his hand, and with surprising speed
+he slashed the cords around Latham’s hands and feet. A little dazedly
+the physician rose from the cot. There was a dull, smoldering fever in
+his eyes as he looked at Ballinger. With startling suddenness his right
+hand shot out, landing a vicious blow between Ballinger’s eyes.</p>
+
+<p>“There—I promised you that!” he exclaimed grittily. “And you!”</p>
+
+<p>Again his powerful fist darted out, and a splash <span class="pagenum" id="Page_320">320</span>of crimson spurted
+from the region of Englebreth’s nose. With a sigh of vast content he
+looked at Cole.</p>
+
+<p>“How in the world did you——”</p>
+
+<p>“Never mind,” Cole interrupted. “Get Carlin on the telephone.” As the
+physician started to obey, his cold, narrowing gaze swept each face in
+the room. “I’ll shoot the moment any one moves or makes a sound,” he
+declared.</p>
+
+<p>His voice had a ruthless ring, and no one moved. Englebreth, breathing
+raspingly, was wiping the blood from his face while he squinted at Cole
+in a dazed way.</p>
+
+<p>The physician hung up the receiver and stepped away from the telephone.</p>
+
+<p>“I got Carlin out of bed,” he reported. “He will be here in a little
+while, and he will bring enough men with him to surround the place.
+These human hyenas will soon be where they belong.” He looked about
+him with a satisfied expression. “I hope Carlin won’t treat the speed
+regulations too tenderly. I’m hungry as the deuce.”</p>
+
+<p>“So am I,” admitted Cole, a trifle absently. The throbbing and pulsing
+of machinery sounded remotely in his ears, a muffled hymn of greed
+and gold-maddened dreams, soon to be silenced forever. He shrugged,
+and a look of fretful responsibility came into his face. “And there
+is Toots,” he went on. “I’ve been neglecting Toots lately. Latham,
+I’m going to give you a piece of advice, with the compliments of The
+Unknown Seven. Keep shy of cats.”</p>
