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.

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 reawakened 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 almost swear I saw a second black window with something on it that was like a snail.
