"None; the Prime Minister and Lord Beamdale saw me do it."
"No doubt whatever," corroborated Mr. Llewellyn John, whilst Lord

"Does anyone else know that it is missing?" asked Malcolm Sage after a short pause.
Sir Lyster shook his head.
"Only we three; and, of course, the thief," he added.
Malcolm Sage nodded. He had tired of the diagrams, and now sat stroking the back of his head.
"Has anyone left the house since the discovery; that is, as far as you know?" he queried at length.
"No one," said Sir Lyster.
"The servants, of course, have access to this room?"
"Yes; but only Walters, my butler, is likely to come here in the evening, except, of course, my secretary."
