have got in."
"I, too, know how you got into the apartment," said Fleming Stone; "and it was without the assistance, and without the knowledge, of either Miss Pembroke or her servant."
Again that wonderful gaze of Fleming Stone's sad, serious eyes seemed to compel Lawrence to speak against his will.
"How did I get in?" he said hoarsely, bending forward as with the breathless suspense of a man taking his last chance.
"It is not an easy matter to explain," said Fleming Stone, "nor can I show the method in this apartment; but if you will all come with me across the hall, I will demonstrate to you the possibility of entering a chained door."
Without a word, we all crossed the hall and entered the Pembroke apartment. It was a cheerful, sunny suite of rooms, and its beautiful furniture and appointments seemed meant for a happy home life rather than grim tragedy. Fleming Stone went first, followed by Laura and George Lawrence. I followed with Janet, and, emboldened by her look of pathetic appeal, I clasped her hand in mine. When we were all inside Fleming Stone closed the door, the night-latch of which, of course, snapped itself.
Lawrence still acted as one hypnotized. Seemingly with no volition of his own, he followed Fleming Stone's movements, keeping his eyes fixed upon the detective as if literally unable to look elsewhere.
After closing the door, Fleming Stone put on the night-chain. For the first time I looked at the chain carefully. It was a heavy brass chain, long enough, when the door was closed, for the end, on which was a sort of knob or button, to reach back to the opening provided for it, and then slide along the brass slot until it stopped at the other end and hung in a loop. It seemed to me no different from dozens of chains I had seen of the same sort.
When it hung finally in position, Fleming Stone turned the knob and opened the door with a jerk, precisely as Charlotte had done on that memorable morning.
"Is it not true," asked Mr. Stone, "that this door, with the chain on thus, has often been violently jerked open?"
"Yes," said Janet; "Charlotte is very strong, and always pulls the door open sharply, forgetting the chain is there. And, too, Uncle Robert has often done the same thing, and his motions were always so vigorous that I thought sometimes he would break the chain."
"There was no danger of breaking the chain," said Mr. Stone; "but the repeated jerks at it have so forced the end of the slot nearest the edge of the door, that the brass is sprung outward, and the knob on the end of the chain may be removed—not as easily as it can be at the other end, it is true, but with some ingenious handling."
As he spoke, Fleming Stone, by some clever exertion, so twisted the knob on the end of the chain that it came out of the near end of the slot, with no necessity of pushing it back to the other end. I saw at once that this could be done also from the outside of the door, there being ample room when the door was ajar to slip one's hand in and free the chain in this manner.
At this demonstration of an actual fact, Fleming Stone did not look at George Lawrence, but at Miss Pembroke.
"You knew of this?" he said.
"I feared it," replied Janet, and I think she would not have spoken but for those impelling eyes upon her. "I remember George was out one evening when he was living here, and I thoughtlessly put the chain on the door and went to bed. The next morning, when I found that he had let himself in in some way, I wondered at it, but concluded that I must have been mistaken, and had not put the chain on. But I had noticed myself that the slot was sprung at this end, and I had been thinking that I would get a new and heavier chain bolt."
My first thought was that Janet's puzzling demeanor was now explained, and I understood why she had so readily accepted my services. She had suspected George from the first, because she knew that with his latch-key and the defective chain-lock he could make his entrance. But his perfect alibi had deceived her, and relieved her fear, so that she was glad or sad according as his alibi was sustained or doubted. Janet's evidence, of course, left no doubt as to George's guilt.
He saw this himself, and, seemingly at the end of his resources, he exclaimed: "It's no use. I may as well confess. I did kill Uncle Robert, but it was not premeditated, or, at least, not until a few moments before the deed. I want to make my confession to my cousin. I owe it to no one else."
But although Lawrence said this, he never once moved his eyes from Fleming Stone's face, and seemed really to make his confession to him.
"It was a violet pin I used, not a hat-pin. I—I had it, by accident, in my coat lapel all Wednesday afternoon at the matinée. On account of disastrous losses in Wall Street that morning, I had determined to kill myself. I'm not of much account, any way, and I was desperate. I knew Uncle Robert would give me no money to repay my stock losses, for he always thought speculation no better than any other sort of gambling—and it isn't. As I sat in the theatre, unconsciously my fingers trifled with the pin, and I conceived a notion of using that to take my own life, instead of a revolver. I went home to dress for dinner, and, still having the pin in my mind, I transferred it from my frock coat to my evening coat. As I stood looking at it while in my room, it occurred to me that were it not for the head of the pin I might push it into my flesh so far as to hide it. It would then be assumed, I thought, that I had died a natural death, and both the family and my memory would be saved the stigma of suicide. Acting on this thought, I laid the pin on the hearthstone and crushed off its glass head with my heel. Without definite intention as to when or where I should carry out my plan, I put the pin in my coat and went on to Miss Waring's dinner. It was as I sat at the dinner table, and looked around at other men of my own age and class, that I suddenly realized I did not want to give up a life which held promise of many years of pleasure, could I but tide over my financial troubles. I knew, too, that at Uncle Robert's death I should inherit enough to make good my losses, and an ample fortune besides. It was then, I think, that the thought came to me, why should not Uncle Robert die instead of myself? He was old, he had no joy in life, he made my cousin's life a burden to her, and his death would free us both from his tyranny. I'm not saying this by way of excuse or palliation, but simply to tell you how it occurred. Like a flash I realized that if my own death by means of the headless pin might be attributed to natural causes, the same would be true of Uncle Robert's death. I knew I could get into the apartment in the same way I had done before, and I knew, too, that as the chain slot was even more pulled out of shape now than it was then, I could with some manipulation replace the chain before closing the door. I think I need not say that I had no thought of implicating my cousin, for I had no thought of the pin being discovered. The idea obsessed me. The deed seemed inevitable. My brain was especially active, and planned the details with almost superhuman ingenuity. I left Miss Waring's at eleven o'clock, calling her attention to the fact purposely. I walked over here rather slowly, planning as I walked. I resolved, as Mr. Stone has remarked, to leave a misleading clue or two behind me. I searched the pavement as I walked, for something that would answer my purpose, and was surprised to see how little may be gleaned along a New York street. I found the two ticket stubs, evidently thrown away by someone, and put them in my pocket. Near here, less than two blocks away, I saw a shining object on the sidewalk, and picked up a key, which I was more than surprised to have traced to Mr. Leroy. I suppose he dropped it when he was hanging around here, beneath my cousin's window, on his way to the midnight train. I then came on to this house, and, after loitering about a minute in the street, I saw the elevator begin to rise. The main front door is always open, and I came in and walked up-stairs. It is easy to evade the elevator, even if it passes. On the stairs I found the time-table. And then I came——"
Lawrence stopped. Even his hardy bravado and indomitable will gave way before the picture that now came into his mind. His swaggering narrative ceased. His eyes fell, his mouth drooped, and he seemed on the verge of collapse.
Fleming Stone's quiet, even voice broke the silence. "And the handkerchief?" he said.
"It came in my laundry, by mistake," answered Lawrence, and he spoke like an automaton, his intelligence seeming to hang on the will of Fleming Stone.
"You brought it with you on purpose?"
"No; not that. When I left
