“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 lookout; 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.”
