"Don't blame them," put in Wimsey. "It was meant to be overlooked, you know. I made it like that on purpose."

The President went on, without seeming to notice the interruption.

"The prisoner informs me that the book with the names and addresses is to be found in this inner compartment, together with certain letters and papers stolen from the houses of members, and numerous objects bearing authentic finger-prints. I believe him to be telling the truth. He offers the combination of the safe in exchange for a quick death. I think the offer should be accepted. What is your opinion, ladies and gentlemen?"

"The combination is known already," said Number Twenty-two.

"Imbecile! This man has told us, and has proved to me, that he is Lord Peter Wimsey. Do you think he will have forgotten to alter the combination? And then there is the secret of the inner door. If he disappears to-night and the police enter his house——"

"I say," said a woman's rich voice, "that the promise should be given and the information used—and quickly. Time is getting short."

A murmur of agreement went round the table.

"You hear," said the President, addressing Wimsey. "The Society offers you the privilege of a quick death in return for the combination of the safe and the secret of the inner door."

"I have your word for it?"

"You have."
