Anstruther came out of a dream presently, and realized with a start that Seymour's deadly revelations were still going on. A moment later, and the Crown Counsel suggested that Seymour should stand down for a moment, and that Bates should take his place. The detective came into the box alert and smiling. He told how he had impersonated the mythical Maggs, and how he had accompanied Anstruther to the City and Provincial Bank.

"At this point I should like to ask you a few questions," said Counsel for the Crown. "I understand that you have become possessed of the service of silver plate to which the last witness has already alluded. He spoke just now of some device of his whereby the service of plate was smeared with grease as it lay on the floor of the vault, and before it was conveyed to Carrington's safe. Now, has this any important bearing on the case?"

"I think you will find that it has an exceedingly important bearing on the case," Bates said. "You will remember, sir, that Mr. Seymour made a special request that the plate should be carefully photographed. You will remember, also, that the prisoner himself carried the plate to the safe and deposited it inside. We have had the plate carefully photographed, with a view to identification by means of finger marks. That is what we call a part of the Bertillon system. But, perhaps, I had better explain."

Bates's explanation was carefully followed by an almost breathless audience. Bates held up a sheet of glass in his hand.

"I have here," he said, "a photograph taken from a silver cigar case. It is the considerably enlarged impression of finger prints left on the cigar case by a burglar who was scared away before he could secure his booty. By comparison of this impression from the cigar case side by side with one of the other permanent prints at Scotland Yard we were enabled to identify and convict the thief."

"Quite so," the barrister said. "The jury follows you. Is it your intention to prove that on the Cellini plate marks have been found corresponding with the lines on the prisoner's hand?"

"This is preposterous," Anstruther cried. "It is nothing less than a vile conspiracy. I defy the police to be able to prove that the marks of my fingers are on the plate. And even if there was more resemblance discovered it would be out of the question for the police to compare them with any impression of my own."

"You are doing no good to your case," the judge interposed. "You will have plenty of opportunity to ask questions later on."

"With the permission of the jury I shall prove that," Bates said. "Before I proceed any further, may I ask your lordship if you will have Sir Frederick Ormond called? Sir Frederick will recollect the night of Lady Barmouth's dance, when one of the guests, disguised as a magician, gave him a sealed packet to take care of. When that packet came to be unsealed and photographed by our experts, we had no difficulty in discovering----"

A deep groan broke from Anstruther's lips.
