“How?”

“Why, he took the jewels to Nice with him when he went to meet Pierrette, and, having acquaintance with Regnier through his friend Raoul, gave them over to ‘The President’ to sell for him, well knowing that Regnier had, like we ourselves, a secret market for such things. I’ve proved, by the way, that this fellow Martin has had one or two previous dealings with Regnier while in various situations in Paris.”

“Well?” I asked, astounded at all this. “That’s the reason they warned me against her. What else?”

“What else?” he asked. “You may well ask what else? Well, I acted boldly.”

“How do you mean?”

“I simply told the dainty Mademoiselle, Raoul, Martin, and the rest of them, of my intention—to explain to the police the whole queer story. I knew quite well that Regnier had the jewels intact in a bag in his room at the Hermitage, and rather feared lest he might pitch the whole lot into the sea, and so get rid of them. That there were grave suspicions against him regarding the mysterious death of a banker at Aix six months before—you recollect the case—I knew quite well, and I was equally certain that he dare not risk any police inquiries. I had a tremendously difficult fight for it, I can assure you; but I stood quite firm, and notwithstanding their threats and vows of vengeance—Mademoiselle was, by the way, more full of venomous vituperation than them all—I won.”

“You won?” I echoed. “In what manner?”

“I compelled Regnier to disgorge the booty in exchange for my silence.”
