“Yet almost the instant he saw me move in the window he turned and ran out of the garden by the back gate, which stood open and by which he had undoubtedly entered. This renewed timidity on his part was so different from the impudence with which he had walked into the sea, that I felt vaguely comforted. I fancied, perhaps, that he feared confronting Arthur more than I knew. Anyhow, I settled down at last, and had a quiet dinner alone (for it was against the rules to disturb Arthur when he was rearranging the museum), and, my thoughts, a little released, fled to Philip and lost themselves, I suppose. Anyhow, I was looking blankly, but rather pleasantly than otherwise, at another window, uncurtained, but by this time black as a slate with the final night-fall. It seemed to me that something like a snail was on the outside of the window-pane. But when I stared harder, it was more like a man’s thumb pressed on the pane; it had that curled look that a thumb has. With my fear and courage re-awakened together, I rushed at the window and then recoiled with a strangled scream that any man but Arthur must have heard.
“For it was not a thumb, any more than it was a snail. It was the tip of a crooked nose, crushed against the glass; it looked white with the pressure; and the staring face and eyes behind it were at first invisible and afterwards grey like a ghost. I slammed the shutters together somehow, rushed up to my room and locked myself in. But, even as I passed, I could swear I saw a second black window with something on it that was like a snail.
“It might be best to go to Arthur after all. If the thing was crawling close all around the house like a cat, it might have purposes worse even than blackmail. My brother might cast me out and curse me for ever, but he was a gentleman, and would defend me on the spot. After ten minutes’ curious thinking, I went down, knocked on the door and then went in: to see the last and worst sight.
“My brother’s chair was empty, and he was obviously out. But the man with the crooked nose was sitting waiting for his return, with his hat still insolently on his head, and actually reading one of my brother’s books under my brother’s lamp. His face was composed and occupied, but his nose-tip still had the air of being the most mobile part of his face, as if it had just turned from left to right like an elephant’s proboscis. I had thought him poisonous enough while he was pursuing and watching me; but I think his unconsciousness of my presence was more frightful still.
