"Half an hour later there was a tap at my door. It was Peter with my coffee. When I had drunk it, we both went along to the Grey Room. As we went, I had a look at the seals on the other doors; but they were untouched. The seal on the door of the Grey Room was broken, as also was the string from the trigger of the flashlight; but the card over the keyhole was still there. I ripped it off, and opened the door. Nothing unusual was to be seen until we came to the bed; then I saw that, as on the previous day, the bedclothes had been torn off, and hurled into the left-hand corner, exactly where I had seen them before. I felt very queer; but I did not forget to look at all the seals, only to find that not one had been broken. "Then I turned and looked at old Peter, and he looked at me, nodding his head. "'Let's get out of here!' I said. 'It's no place for any living human to enter, without proper protection.' "We went out then, and I locked and sealed the door, again. "After breakfast, I developed the negative; but it showed only the door of the Grey Room, half opened. Then I left the house, as I wanted to get certain matters and implements that might be necessary to life; perhaps to the spirit; for I intended to spend the coming night in the Grey Room. "I got back in a cab, about half-past five, with my apparatus, and this, Peter and I carried up to the Grey Room, where I piled it carefully in the center of the floor. When everything was in the room, including a cat which I had brought, I locked and sealed the door, and went toward the bedroom, telling Peter I should not be down for dinner. He said, 'Yes, sir,' and went downstairs, thinking that I was going to turn in, which was what I wanted him to believe, as I knew he would have worried both me and himself, if he had known what I intended. "But I merely got my camera and flashlight from my bedroom, and hurried back to the Grey Room. I locked and sealed myself in, and set to work, for I had a lot to do before it got dark.
