"Yes, I will tell you everything now," she quickly replied.

"Before you do so it is my duty to warn you that any statement you make may be used in evidence against you at your trial," Merrington said, with a swift resumption of his official manner. "At the same time, I think you will be acting in your own interest by keeping nothing back."

"I quite understand. But it is such a strange story that I hardly know how to begin."

"Tell me everything from the first. That will be the best way."

"That night I went up to Mrs. Heredith's room just to see her," she commenced, almost in a whisper. "My mother had told me earlier in the evening that she was alone in her room suffering from a headache. I thought I would take the opportunity while the others were at dinner to go up to her room and ask her if she wanted anything. So I left my mother's room and walked quietly down the hall to the left wing. There was nobody about. All the guests were at dinner, and the servants were busy in the kitchen and the dining-room.

"When I got upstairs I noticed that Mrs. Heredith's door was open a little, and I saw that there was no light in the room. I thought that strange until I remembered she had been suffering from a bad headache, and probably had turned off the light to rest her head. I did not knock because I thought she might be asleep. I was just going to turn away when I heard a sound like a sob within the room. I listened, and heard it again. I hardly knew what to do at first, but the thought came to me that perhaps Mrs. Heredith was worse, and needed someone. So I pushed open the door and went in.

"I know the moat-house well, so I was aware that the switch of the electric light was by the side of the fireplace, near the head of the bed, and not close to the door, as in the other rooms. To turn on the light I had to walk across the room. It was very dark, and I walked cautiously for fear of stumbling and alarming Mrs. Heredith. Twice I stopped to listen, and once I heard a sound like somebody whispering. I was dreadfully nervous because I didn't know whether I was doing right or wrong by going into Mrs. Heredith's room like that, but something seemed to urge me on.

"I must have mistaken my direction in the dark, for I couldn't find the electric switch. I kept running my hand along the wall in search of it, and while I was doing this, somebody caught me suddenly by the throat.

"All the blood in my veins seemed to turn to ice, and I screamed loudly. Immediately I screamed the hand let go, but I was too frightened to move. It was so silent in the room then, that I could hear my own heart beating, but as I stood there by the wall not daring to move I thought I heard a rustling sound by the window. My hands kept wandering over the wall behind me, trying to find the switch of the light. Then, suddenly, there was a dreadful sound—the report of a gun. It seemed to fill the room with echoes, which rolled to the window and back again. As the sound of the report died away, my fingers touched the switch and I turned on the light.

"I was standing close to the head of the bed, and the first thing I noticed was something glittering on the carpet at my feet. I stooped and picked it up. It was a revolver. Then my eyes turned to the bed, and I saw poor Mrs. Heredith. She was lying quite still with blood on her mouth. I could see that she was still alive, because her eyes looked at me. At that terrible sight I forgot everything except that she was in agony. I was bending over her wiping her mouth when I caught the sound of footsteps running up the stairs. It flashed across my mind that I must not be found there, in a room where I had no right to be, holding in my hand a revolver which had just been discharged. I switched off the light and ran out of the room. The light from the landing outside guided me to the door. I had just time to get outside and slip behind the velvet curtains when some of the gentlemen appeared on the landing.
