About ten yards in front of him, crawling along the floor, was a man's hand. Eustace stared at it in utter astonishment. It was moving quickly, in the manner of a geometer caterpillar, the five fingers humped up one moment, flattened out the next; the thumb appeared to give a crab-like motion to the whole. While he was looking, too surprised to stir, the hand disappeared round the corner. Eustace ran forward. He no longer saw it, but he could hear it as it squeezed its way behind the books on one of the shelves. A heavy volume had been displaced. There was a gap in the row of books where it had got in. In his fear lest it should escape him again, he seized the first book that came to his hand and plugged it into the hole. Then, emptying two shelves of their contents, he took the wooden boards and propped them up in front to make his barrier doubly sure.
"I wish Saunders was back," he said; "one can't tackle this sort of thing alone." It was after eleven, and there seemed little likelihood of Saunders returning before twelve. He did not dare to leave the shelf unwatched, even to run downstairs to ring the bell. Morton the butler often used to come round about eleven to see that the windows were fastened, but he might not come. Eustace was thoroughly unstrung. At last he heard steps down below.
"Morton!" he shouted; "Morton!"
"Sir?"
"Has Mr. Saunders got back yet?"
"Not yet, sir."
"Well, bring me some brandy, and hurry up about it. I'm up here in the gallery, you duffer."
"Thanks," said Eustace, as he emptied the glass. "Don't go to bed yet, Morton. There are a lot of books that have fallen down by accident; bring them up and put them back in their shelves."
Morton had never seen Borlsover in so talkative a mood as on that night. "Here," said Eustace, when the books had been put back and dusted, "you might hold up these boards for me, Morton. That beast in the box got out, and I've been chasing it all over the place."
