"Well," said Mr. Britton, when, at the end of the séance, he returned his treasures to the bag, "you have now got twenty-three of our cheques, to all intents and purposes. I hope you are not going to make any unlawful use of them—must tell our cashiers to keep a bright look-out; and"—here he lowered his voice impressively and addressed himself to me and Polton—"you understand that this is a private matter between Dr. Thorndyke and me. Of course, as Mr. Blackmore is dead, there is no reason why his cheques should not be photographed for legal purposes; but we don't want it talked about; nor, I think, does Dr. Thorndyke."
"Certainly not," Thorndyke agreed emphatically; "but you need not be uneasy, Mr. Britton. We are very uncommunicative people in this establishment."
As my colleague and I escorted our visitor down the stairs, he returned to the subject of the cheques.
"I don't understand what you want them for," he remarked. "There is no question turning on signatures in the case of Blackmore deceased, is there?"
"I should say not," Thorndyke replied rather evasively.
"I should say very decidedly not," said Mr. Britton, "if I understood Marchmont aright. And, even if there were, let me tell you, these signatures that you have got wouldn't help you. I have looked them over very closely—and I have seen a few signatures in my time, you know.
