"You believe," he asked, "that the testimony of the secret chamber is absolutely convincing of Silwood's being alive?"

"Yes."

"Was there no one else who could have opened it?"

"No one but the maker, and he is out of the question. Who, beside Silwood, would have any object in opening it?"

"The conclusion is just," acknowledged the Ambassador; "and I believe, with you and your father, that the man is alive; everything undoubtedly points that way. But as I hinted, I think, to you already, it is really a case for the police."

"Later it will in all probability be," said Gilbert; speaking with great earnestness. "But at present my strong desire and hope is that I may be able to trace Silwood, lay hands on him, and get from him, in some way or other, an explanation of certain transactions which he negotiated in the course of his defalcations. If I were to have him arrested when found, it would most likely be impossible to get him to say anything."

"I understand," said the Ambassador, but he looked at Gilbert dubiously.

"I believe he had a confederate," Gilbert went on, as he saw Lord Prestonkirk did not altogether follow him. "Let me explain a little more fully. The accountant who went over his books and papers found that large transactions had taken place between Silwood and a certain James Russell. Inquiries were made about this Russell, and it turned out he was quite a poor man, or, at all events, a man living in a very poor way in Stepney—not in the least the sort of man to engage in large financial operations. I fancy he was a man of straw over whom, perhaps, Silwood may have had some hold, and that Silwood made use of him when a man of straw was needed. We found that this man had recently left Stepney, and I have employed a private detective to hunt him down."

"What did you say his name was?"

"James Russell."
