Jenkins came back, the book in his hand, and gave it to him. Amberley flicked over the leaves, shook it, peered down the back, carefully felt the thickness of the boards.

"Too thrilling!" murmured Lady Matthews.

But Amberley was looking puzzled. "I seem to be wrong," he said. "Yet somehow — I don't think I am." He glanced thoughtfully at his uncle. "I wonder."

"What do you wonder?" said Sir Humphrey. "Pray don't be obscure!"

"Whether anyone entered your room tonight," said Amberley.

His wife interposed. "Dear Frank, all most intriguing, but don't annoy your uncle."
