"You must know, then," said Philip Darwin, "that I was the child of a second marriage contracted between my father and a young woman who had just begun to earn a name for herself upon the stage. She endured two years of walking the straight and narrow path as his wife, and then she eloped with an actor friend. My father hushed the scandal and withdrew from social life, becoming morose and bitter and narrower than ever, watching over me with a zealous eye as I grew older, and endeavoring to eradicate the talents which I had inherited from her, looking with particular disfavor on my ability to act and mimic the speech of those about me.

"Knowing my inherited love of pleasures of all kinds he strove to curb me by refusing to let me go out in the evenings with my young companions. This I considered an indignity since I was then old enough to be my own master, and so I took matters into my own hand, retiring early and then sneaking away from my rooms to join my friends. This practice I continued until by an unforeseen chance I was among those arrested in a raid upon a gambling-house. I would have given a false name but unfortunately the Sergeant knew me, and of course the affair came to the ears of my father.

"He was exceedingly wroth and threatened to disinherit me if I ever disobeyed him again. I did not want to lose my chance to secure his fortune, which would come to me intact since Robert, my older brother, was dead, and my sister, Leila, had run away from home, so I remained at home on my best behavior. It was just at this time that I came across an old book in the study that gave the history of the house from which ours had been copied. I investigated and found the door in the masonry, took an impression of the lock, had a key made, and so discovered the secret room. That room gave me an idea. I knew that it was next the study although it had never been cut through, but this fact did not trouble me. My father had planned to take me to Europe with him, but I told him that I preferred to remain at home and look after the business, into which I had been taken as junior partner on my twenty-first birthday. Thinking that I had reformed he gave his permission for me to have a safe built in the study, since I had pointed out to him that now that I was a man of affairs I needed such a contrivance for my personal papers. But though he left for Europe without me he did not altogether trust me, for I discovered that his lawyer had orders to telegraph my father if at any time he learned that I had deviated from the rule of conduct laid down for me to follow.

"I determined to outwit him. I sent Mason away, hired some workmen, had a door cut between the study and the secret room and had a safe built into the wall as a blind. Then I spent the rest of the year in evolving the character of Cunningham. He should be a young law student, red-haired, red-bearded, fastidious. Also as Darwin, I adopted glasses to make myself and Cunningham as opposite as possible in appearance.

"When my father returned he heard no scandal of me for Cunningham had taken young Darwin's place in the beaumonde. Thereafter I had no difficulty in getting away, retiring early and then leaving the house by the secret entrance, after changing to Cunningham in the little room.

"After my father's death Cunningham was of no further value to me, but I was too clever to utterly destroy him, since I had no idea when I might need him again. So he told his friends that a relative had died abroad, leaving him a fortune, and that he was going on a trip around the world. Then Darwin came back and took his place in the social world.

"I pass over the next few years, in which I played the fool and speculated beyond my means. Eight months ago I was in desperate need of money, although none knew of it, and I saw that my only course lay in marrying some wealthy woman.

"I looked around me and decided that Arthur Trenton's daughter would serve my purpose. I made friends with her brother and discovered to my annoyance that the young lady in question had just engaged herself to a young broker by the name of Carlton Davies and that the wedding was scheduled to take place in a very short time. This was something of a set-back, since I knew that Miss Trenton was not likely to jilt her lover for a man she was barely acquainted with. But once I make up my mind to obtain a thing I never give up until that thing is mine. I cast about for a way to make her marry me, and having cultivated her brother, Dick, for a month, I laid my plans accordingly.

"I enticed the boy, who was inclined to be wild, to a gambling-den, after I had taken the trouble to get him fairly intoxicated. I had hired a jail-bird to quarrel with Dick and when the man pretended to go for the boy, I shot and killed him, telling Dick that he had done it. He became frightened and I took him to his home, where his father was told my version of the tale, and Dick was dispatched to Chicago. Then I forced Ruth to marry me to save her brother from going to the chair for something he had never done!"

Darwin paused in his narrative to puff his cigar and to let us sufficiently admire the cleverness that had conceived such a plan. Admire! I could only shudder at the thought that there could be in existence a man who could carry out such diabolical schemes in cold-blood, and actually pride himself on his accomplishment.

"After the marriage I made Ruth sign away her dower rights as well as her dowry, all to save her brother. Then I took up my old way of living again. But now there was a fly in my ointment. People began to talk, and I had enough of my father in me to make gossip distasteful to me. Yet marriage was a bore, I discovered, and so I resurrected the lawyer, Cunningham. If as Darwin I must endure life with Ruth, as Cunningham I would be as gay as I chose. I hired an apartment and began my double life.

"When Darwin was bored to distraction by prosaic affairs, he would take a business trip and Cunningham would have his fling. When pleasures cloyed, Cunningham would be off to see his out-of-town clients and Darwin would return to the city. The excitement and the danger of detection that this sort of existence afforded fascinated me and I should have kept it up indefinitely if fate in the person of a former teller of the Darwin Bank had not intervened.

"This man, James Gilmore, who had been my dupe ten years before, and had since been in jail, was at the gambling-den the night I shot Coombs, and he realized the trick I had played upon Dick. I thought at the time when Gilmore fell that I had killed him also (I did not know him at the time. I merely shot at him on the principle that dead men tell no awkward tales), but by some freak of chance he escaped unhurt and became acquainted with Richard Trenton.

"The first intimation I had that my plans had gone awry was in a letter from Dick explaining the circumstances. I thought the matter over and finally made up my mind to go to Chicago as Cunningham, to kill Dick, and then return as Darwin, abolishing forever the character of the lawyer.

"When I reached Chicago, however, and saw Dick, a new plan, more daring, more subtle, more pleasing in every way leapt fully matured into my mind, since by means of it Darwin would disappear and Cunningham would remain, free to live his life unhampered by the marriage tie.

"Dick had grown a beard. Trim it as mine was trimmed, give him a pair of gold eyeglasses, and he could pass superficially for myself. I marveled at the likeness then. Now I know it was only natural, since it seems he was my nephew as well as my brother-in-law.

"I pretended as the lawyer to be on his side, returned to New York, and wrote him a letter in which I declared that as Ruth refused to divorce me, which was one of the terms of reparation Dick insisted upon, he had better call upon me and talk things over. He walked into the trap I had laid for him, and telegraphed that he would come to see me."

Again Darwin paused and eyed us in that strange exultant manner.

"You will think, perhaps, that it was a daring thing to do, this that I had in mind, but its very audacity would serve to carry it through, I knew. Have you ever studied psychology? I commend it to you, for my knowledge of that subject was the foundation stone upon which I built.

"When a man is found shot in his own study, remaking his own will, looking like himself to all outward appearance, the conclusion is naturally that the dead man is the one whom the world believes him to be, that is, the master of the house. Also I had no fear that the deception would be remarked. Orton was near-sighted, Mr. Davies (for as I shall show you presently, I intended to bring him into this affair also), knew me only slightly, had not seen Dick for six months, and never with a beard, besides being under the belief that the boy was in Chicago, and Ruth would be too overwrought to notice anything amiss. The only one I really feared was Lee, as he knew me thoroughly. I determined to get rid of him. The question was, how? and the answer was supplied by the girl, Cora Manning.

"I had been intrigued by her beauty, but had no thought, despite my nephew's assertions, beyond being allowed to gaze upon her occasionally, but the night of the sixth as she told me of her broken ring I knew I loved her and wanted her for my own. I saw a way ahead of me and seized the opportunity presented to me.

"I inveigled her into giving me the ring and the next morning I gave Lee to understand that the girl had been false to him. He believed me and I knew him well enough to guess that he would break off the engagement, leaving the way free for me later. I also ordered him to leave my house for his insolence to me, thus getting him out of the way for that night.

"It was at this point in the game that a new element was introduced. I had meant merely to leave Ruth a supposed widow, but when Orton showed me the letter she had written to her former lover, I determined to make her pay for my crime. I told him to piece the letter together and bring it to me, and then I left for the office.

"And now I was guilty of my first error. I permitted my infatuation for Cora to get the better of my discretion, and told her to come to the house at ten-forty-five, knowing I would have time to see her in the secret entrance and get rid of her before Dick was scheduled to arrive. I should have known better, for it was too dangerous a game to play.

"At ten-thirty that night I called Ruth to the study and upbraided her, threatening Mr. Davies in such terms that she took fright and declared she would send for him to warn him. I only laughed and thoroughly roused she left me to call her lover to her, as I hoped she would.

"Then I locked the study door, opened the secret entrance as I had promised, and waited for Cora. She did not come, and when eleven struck I gave her up and was on the point of leaving the study to relock the entrance when Dick suddenly stepped in through the window, one half-hour before he was due. We talked for twenty-five minutes, while I waited for Mr. Davies' arrival. Dick insisted upon seeing Ruth at once. I told him she had gone out with friends and would not return until eleven-thirty.

"At eleven-twenty-five I heard a motor drive up, and guessing it must be Mr. Davies who had come, I set to work to carry out my plan. I told Dick Ruth had come, and he sprang up and went to the door. I followed him and as I did so I soaked a handkerchief with chloroform from a bottle I had in my pocket, and as he fumbled with the key I came up behind him and pressed the handkerchief over his face. As he sagged into my arms I switched off the light and carried him to the secret room, depositing him on the couch.

"Then I returned to the study, unlocked the door, and called in Orton that he might take away with him a mental image of myself seated in my chair, as I later intended that Dick should sit. When Orton was gone I relocked the door, and returned to Dick. I exchanged clothing with him, and it was no easy task, for he lay an inert mass. Then I trimmed his beard and placed my eyeglasses on his nose. Finally, I took out my revolver and shot him through the heart as I supposed, but he had come out from under the influence of the anesthetic and as I fired he moved so that the bullet only penetrated his lung. I knew that he was done for in any case and as I bent down to pick him up I noticed the ring on his finger. I never wore rings, and that one was too familiar to Ruth to risk leaving it. I was removing it with care when I heard a step on the stairs of the entrance. I remembered Cora and dared not let her guess the truth. Hastily I snatched off the ring, slipped it in my pocket and carried Dick into the study, setting him down in my chair. Then I hid behind the curtains of the window, which was nearest the safe. I saw her enter, and as she advanced toward the table where only the lamp was lighted, I slipped into the safe and switched it off.

"I took off my coat and as she fell against me in the dark I flung it over her head, and carried her to the divan in the secret room. Then I went about my other business, for I had much to do. I cleaned my gun, and recharged it, removing the bullet from the cartridge I intended to fire later. I returned to the study, pushed back the chair so that it would look as though Darwin had been shot when he rose to meet someone, arranged the matter of the wills, and left a word half finished upon the testament I was supposed to have been making, burning the old one which I had torn up when I recalled it was in Lee's favor and not Ruth's.

"When I saw that I had bruised Dick's finger I flung Cora's ring, from which the stone had dropped that morning, on the top shelf of the safe in order to explain the abrasion with some degree of plausibility, since I knew that Lee had seen the ring on my finger in the morning. Then when everything was as perfect as human ingenuity could make it, I went to the door and unlocked it, that Ruth might find no obstacle to her entrance. I switched on the lights for a moment for a last survey and saw a handkerchief lying near the door. When I picked it up I saw that it was Ruth's, but caution prevailed and I smelled it to make sure, knowing well that Cora used Rose Jacqueminot, since I had adopted it myself after becoming acquainted with her. The handkerchief was unscented and I decided to add it to the evidence against Ruth. I put out the light, stained the handkerchief with blood, arranged it in Dick's hand, turned out the lamp, and waited for Ruth.

"How did I know she would come to the study? Because I had decoyed Mr. Davies to the house to bring about that very result. He was a man and he loved her and he feared what I might do to her if I remained in possession of that letter. I had purposely told her I was going out and had let her see me throw the letter in the table-drawer. Mr. Davies, I knew, would urge her to get the letter.

"When she came in and I heard her fumbling with the contents of the drawer I fired my revolver. I knew it would startle her, and that she would move away from the table, so I slung the gun along the carpet, trusting that it would carry as far as her feet. Then I hastened to the safe and turned on the lamp, closing the door to behind me, but remaining where I could hear what occurred in the study.

"I heard Mr. Davies' order to Orton, and locking the safe I hastened through the entrance to the front door, letting myself in just as they disappeared into Ruth's apartments. I went into the dining-room and opened a bottle of wine, into which I mixed a sleeping potion. While I was there I heard the doctor arrive and go upstairs, then I returned the way I had come, poured out a glass of the wine and gave it to Cora. Then I locked the entrance doors and left her there to sleep while I returned to the Corinth as Dick, so that there would be no undue search made for him. The next morning I went back to my apartments as Cunningham, and from there to the inquest.

"When Ruth had been adjudged guilty, I determined to get rid of Lee, since his actions told me plainly he knew something of Cora's visit. I decoyed him from the club with a fake message and had him kidnapped, but could get nothing from him. I decided to keep him a prisoner until after Ruth had paid the penalty for the crime.

"My thought now reverted to Cora, but I dared not return to the house that night, as the police were still in charge. I waited until they had left about nine o'clock the next morning, and went to the secret room, where I found Cora awake. It was too risky a matter to take her to my other apartments, besides she knew too much to suit me, so I impersonated Lee to kill her love for him. Then as Cunningham I would rescue her and through her gratitude I could earn her love. I did not guess she had a revolver or things might have taken a different turn.

"The afternoon of the ninth I carried out the plans for the suicide of Richard Trenton. It was necessary to account for his disappearance, since two men were gone and there was only one body which could be produced. It was I who jumped in the river. It was an unpleasant duty, but I had to make some sacrifice to attain my ends. I swam down the shore and made my way to Chinatown to my refuge at Hi Ling's.

"From then on I faced the world as Cunningham, and in the end I should have triumphed but for one thing. Mr. Davies' refusal to believe Ruth guilty brought a new element into the case, a man with brains as keen as my own, who was not to be duped as I had fooled the police. He was suspicious of Cunningham from the first, but I did not think that even he could uncover the truth, so in the end I lost."

Darwin ceased speaking and there was silence in the room for a moment, then unexpectedly he rose and turned to McKelvie. "You are clever, but you haven't got me yet. You think to try me. The man doesn't live who can put me in a cell."

Even as he spoke, before we could grasp the meaning of his rapidly uttered words, he sprang down the room toward the door, wrenching it open as Jones fired. We saw Darwin make for the stairs and we were after him in a second. On the floor above he rushed into his dressing-room, and as we entered we saw him disappear into the secret closet. There was a whirring sound and a cry of dismay, then silence, horror-filled.
