"There was nobody in the passage, and I gained my own room and locked the door. I think I must have fainted, or become unconscious, for I remember nothing more after throwing myself on my bed, and when I came to my senses the dawn was creeping in through my bedroom window. I was very cold, and dazed. I crept into bed without taking off my clothes, and fell asleep. When I awoke it was broad daylight, and as I lay in bed I heard the kitchen clock chime seven.
"I got up, and went into grandmother's room. A little while afterwards Ann came up with some tea, and she told me that Mr. Penreath had gone away early, without having any breakfast. She told me that she had found Mr. Glenthorpe's room empty, with the key in the outside of the door. She was afraid something had happened to him, so she had sent for Constable Queensmead. I did not tell her what I had seen in the night. I wanted to be alone, to think. I could not understand how Mr. Glenthorpe's body had disappeared from his room. I think I hoped that I would presently wake up and find that what I had seen during the night was some terrible dream. But Ann came up a little later and told me that Mr. Glenthorpe's body had been discovered in the pit on the rise, and that Mr. Ronald, as she called Mr. Penreath, was suspected of having murdered him.
"When she told me that I felt as though my blood turned to ice. I knew it was true—I knew that he had killed Mr. Glenthorpe because he wanted money—but I knew that in spite of all I wanted to shield and help him. I kept in my grandmother's room all day, determined to keep silence, and tell nobody about what I had seen during the night. The one thing that worried me was the knife which I had put behind the picture on the wall. I tried once to go into the room and get it, but the door was locked, and I dared not ask for the key.
"Then in the afternoon the police came from Durrington. I did not know who you were when you came with them into my grandmother's room, but as soon as I saw you I was afraid, though I tried hard not to let you see it. I knew you were cleverer than the others. But your eyes seemed to go right into mine, and search my soul. I asked my father afterwards who you were, and he said your name was Mr. Colwyn, and that you were a London detective. I had read about you; I knew that you were famous and clever, and after seeing you I felt that you would be sure to discover my secret, and put Mr. Penreath in prison.
"That night when I was downstairs, I heard you and the police officer talking in the room where you had dined, and I listened at the door. When I heard you say that you were not certain who committed the murder, I was very much surprised, because up till then I felt quite certain that you would think Mr. Penreath was guilty. I believed if you found the knife you would alter your opinion, Ann having told me that the police knew that Mr. Glenthorpe had been murdered with a knife which Mr. Penreath had used at dinner. The idea came into my head that if I could get the knife before you found it, you might go on thinking that somebody else had committed the crime, and perhaps persuade the police to think so as well.
"I made up my mind I would go into the room that night and get the knife. I knew that the door was locked, and that the police officer had placed the key on the mantelpiece in the bar parlour. During the evening I kept downstairs at the back of the passage waiting for an opportunity to get it. You both stayed there so long that I did not think I should get the chance.
"After you went upstairs to bed Mr. Galloway called Charles to get him some brandy. Charles came out from his room to get it. Mr. Galloway followed him into the bar. While he was there I slipped into the room and got the key, and left the key of my own room in its place. I did not think the police officer would notice the difference, but it was a risk I had to take. Then I ran up to my room.
"Although I had got the key I was for some time afraid to use it. I could not bear the thought of going into that room, and to get there I had to go past your door; I did not like that.
"Then I crept out along the passage as quietly as I could, carrying my shoes, for I had made up my mind that after I got the knife I would take it across the marshes to the breakwater and throw it into the sea. That was the one place where I felt sure you would not find it. I carried a candle in my hand, but I dared not light it until I got past your door, in case you were awake and saw the light. When I reached Mr. Glenthorpe's room I lit the candle and unlocked the door, turning the key as gently as I could. But it made a noise, and, as I stood listening, I thought I heard a movement in your room. I blew out the candle, stepped inside the room, took the key out, and locked the door on the inside.
"I do not know how long I stood there listening in the dark, but I know that I was not as frightened as I had expected to be—at first. I kept telling myself that Mr. Glenthorpe had always been kind to me while he was alive, and that he would not harm me now that he was dead. I did not look towards the bed, but kept close to the door, straining my ears to catch any sound in the passage outside. But after a while I began to get frightened in that dark room with the door locked, and dreadful thoughts came into my mind. I remembered a story I had read about a man who was locked up all night in a room with a dead body, and was found mad in the morning, and the position of the corpse had changed. It seemed to me as though Mr. Glenthorpe was sitting up in bed looking at me, but I dared not turn round to see. I knew that I must get out of the room or scream. I lit the candle, felt for the knife behind the picture, and opened the door. As soon as the candle was alight I felt braver, and I looked out of the door before going into the passage. I could see nothing—all seemed quiet—so I came out of the room and locked the door behind me and went downstairs.
