"On that morning," Wrayson began, "I returned home about twelve o'clock, let myself in with my own latch-key, and found a woman standing before my open desk going through my papers." "A friend?" the Colonel asked. "A complete stranger!" Wrayson answered. "Her surprise at seeing me was at least equal to my own. I gathered that she had believed herself to be in the flat of Morris Barnes, which is the corresponding one above." "What did you do?" the Colonel asked. "What I should have done I am not sure," Wrayson answered, "but while I was talking to her the telephone bell rang, and I received that message which I spoke about at the inquest. It was a mysterious sort of business—I can hear that voice now. I was interested, and while I stood there she slipped away." "Is that all?" the Colonel asked. "No!" Wrayson answered with a groan. "I wish to God it was!" The Colonel moved his position a little. The cigar had burnt out between his fingers, but he made no effort to light it. "Go on," he said. "Tell me the rest. Tell me what happened afterwards." "I wrote down the message for Barnes and left it in his letter-box. There seemed then to be no light in his flat. Afterwards I lit a pipe, left my door open, and sat down, with the intention of waiting till Barnes came home and explaining what had happened. I fell asleep in my chair and woke with a start. It was nearly three o'clock. I was going to turn in when I heard the jingling of a hansom bell down below. I looked out of the window and saw the cab standing in the street. Almost at the same time I heard footsteps outside. I went to the door of my flat and came face to face with the girl descending from the floor above." "At three o'clock in the morning?" the Colonel interrupted. Wrayson nodded. "She was white and shaking all over," he continued rapidly. "She asked me for brandy and I gave it to her; she asked me to see her out of the place, and I did so. When I opened the door to let her out and we saw the man leaning back in the cab, she moaned softly to herself. I said something about his being asleep or drunk—'or dead!' she whispered in my ear, and then she rushed away from me. She turned into the Albert Road and disappeared almost at once.
