I looked round the room in vague surprise, not at all realizing what had happened, making vain and idle surmises by way of explanation, and wondering at the stirring of black waters by an idle word, and the trivial change of an ornament. "This is some petty business, some whim on which I have jarred," I reflected; "the professor is perhaps scrupulous and superstitious over trifles, and my question may have outraged unacknowledged fears, as though one killed a spider or spilled the salt before the very eyes of a practical Scotchwoman." I was immersed in these fond suspicions, and began to plume myself a little on my immunity from such empty fears, when the truth fell heavily as lead upon my heart, and I recognized with cold terror that some awful influence had been at work. The bust was simply inaccessible; without a ladder no one could have touched it. I went out to the kitchen and spoke as quietly as I could to the housemaid. "Who moved that bust from the top of the cupboard, Anne?" I said to her. "Professor Gregg says he has not touched it. Did you find an old step-ladder in one of the outhouses?" The girl looked at me blankly. "I never touched it," she said. "I found it where it is now the other morning when I dusted the room. I remember now, it, was Wednesday morning, because it was the morning after Cradock was taken bad in the night. My room is next to his, you know, miss," the girl went on piteously; "and it was awful to hear how he cried and called out names that I couldn't understand. It made me feel all afraid, and then master came, and I heard him speak, and he took down Cradock to the study and gave him something." "And you found that bust moved the next morning?" "Yes, miss, there was a queer sort of a smell in the study when I came down and opened the windows; a bad smell it was, and I wondered what it could be. Do you know, miss, I went a long time ago to the Zoo in London with my cousin Thomas Barker, one afternoon that I had off, when I was at Mrs. Prince's in Stanhope Gate, and we went into the snake-house to see the snakes, and it was just the same sort of a smell, very sick it made me feel, I remember, and I got Barker to take me out. And it was just the same kind of a smell in the study, as I was saying, and I was wondering what it could be from, when I see that bust with Pitt cut in it standing on the master's desk, and I thought to myself, now who has done that, and how have they done it? And when I came to dust the things, I looked at the bust, and I saw a great mark on it where the dust was gone, for I don't think it can have been touched with a duster for years and years, and it wasn't like finger-marks, but a large patch like, broad and spread out. So I passed my hand over it, without thinking what I was doing, and where that patch was it was all sticky and slimy, as if a snail had crawled over it. Very strange, isn't it, miss? and I wonder who can have done it, and how that mess was made."
