Harold intimated that he did want the stone immediately. Slowly Benstein was recovering. The rich red blood was creeping into his face again.

"It is impossible," he said. "Usually I keep most of my valuables here. But I recognised the political as well as the pecuniary value of the Blue Stone, and I did not dare. The stone is at the Bank of England, and I cannot get it before ten to-morrow. It is very unfortunate."

"Very," Harold said dryly. "But we must make the best of it. I have a pretty shrewd idea where the stone is, but my guess would not have been the Bank of England. We don't propose to redeem the gem; we suggest that you should let the Shan have it for two or three days on the understanding that when the business is completed your charge is increased by the sum of two thousand pounds."

"But this is not business," Benstein pleaded. "Under the peculiar circumstances——"

"Precisely," Harold interrupted dryly. "Under the peculiar circumstances you are going to accommodate us. Mr. Benstein, I fancy that you and I understand one another."

Benstein's eyes dropped, and the fat cigarette between his fingers trembled. He muttered the talisman word "business" again; but he was understood to agree to the terms offered. He was shakily eager to offer his distinguished guests refreshments of some kind, but Denvers dragged the Shan away. Once in the street, the latter stopped and demanded to know what the pantomime meant.

"It's pretty plain," Harold said. "Old Benstein hasn't got your jewel at this moment."

"Hasn't got it? Do you mean to say that he...? Preposterous! But in the morning——"

"In the morning it will be all right again. In the morning you will see quite another Benstein—a Benstein who has changed his mind, and will refuse to part with the Blue Stone so long as a single penny remains unpaid. I startled him to-night. I got astride of that figment of a conscience of his. But I am going to help you to clench the business. Come along."

"Where are you going to?" the Shan asked feebly.
