We were both tired that evening and we turned in early after supper. I had left instructions to call me if there was any change in Freeman's condition, but I anticipated none before the morning. The nurse seemed a competent woman, and I felt easy in leaving him to her care. I slept like a log, my rest untroubled by any dreams. Towards morning, as it seemed to me, I woke up with that curious sense of something happening which arouses one at times by appeal through some subconscious perception. Five minutes before a thunderstorm would have failed to rouse me; now instinct dragged me up sitting in my bed, of a sudden keenly and alertly awake. I listened. Someone was moving in the surgery below. Mrs. Searle went to bed always at ten, and I had the impression of having slept already for several hours. I struck a match softly and looked at my watch. It was a quarter to twelve, earlier than I had thought. I felt on the bureau for my revolver, which I had taken to my room that evening, and opened the door noiselessly. It was not Herrick, for I could hear his regular breathing through the keyhole opposite. At the foot of the little flight of stairs a faint light glimmered. The stairs opened directly from the surgery, and it was my custom to leave the door at the bottom open during the night. Now it was closed, and the light that I saw filtered through the crack. I crept quietly down and pushed it open, revolver in hand. A pocket electric lamp lay on the desk, and by its light a man was searching through one of the desk drawers. It was a small drawer which had been always locked; I fancied that it contained some private papers and affairs of Lennox's which he had put together there before leaving. The man's back was towards me, but I recognized instantly the shabby tweed coat, the soft felt hat pulled low down over his head. It was Crowfoot. I don't know what I had expected; certainly not him. I lowered the revolver and stepped forward. "Were you looking for anything, Mr. Crowfoot?" At the sound of my voice he turned; his hand shot out towards the electric lamp, and instantly the room was in darkness. For a second we stood there, neither moving, and we could hear each other's breathing across the room. "Light that lamp," I said quietly. "If you have any explanation I am ready to hear it. I have a revolver in my hand, and if you attempt to move I shall be compelled to treat you like any other common housebreaker."
