"Ay, that's the thing; I don't read much of the lingo myself, but I gave him tips at Longchamps last month, and we came back in a dog-cart together. It was then that he put me on to the stones and planted me with a false name."

"What did he say?"

"Said that some mad cove at Raincy had buried a necklace worth two thousand pounds with his wife, and that the dullest chap out could get into the vault and lift it. I'd had a bad day, and was almost stony. He kept harping on the thing so, suggesting that a man could get to America with five thousand in his pocket, and no one be a penny the wiser or a penny the worse, that I went off that night and did it, and got a fine heap for my pains. That's what I call a mouldy pal—a pal I wouldn't make a doormat of."

"And you sold the booty to the old Frenchman in the Rue de Stockholm?"

"Exactly! he gave me a tenner for it, and I'm crossing to England to-night. No place like the old shop, guv'ner, when the French hogs are sniffing about you. I guess there's a few of them will want me in Parry in a day or two; and that reminds me, you can do the noble if you like, and send the other chips to the Elephant Hotel at Cambridge last post to-morrow."

I told him that I would, and left. You may ask why I had any truck with such a complete blackguard, but the answer is obvious: I had guessed from the first that there was something in the mystery of the green diamonds which would not bear exposure from Brewer's point of view, and his tale confirmed the opinion. I had learnt from it two obvious facts: one that Jules Galimard was anything but the friend of my friend; the other, that this man knew perfectly well that a sham diamond necklace was buried with Madame Brewer. It came to me then, as in a flash, that he, and he alone, must have stolen, or at least have come into possession of, the real necklace which I had made.

How to undeceive the good soul who had entrusted me with his case was the remaining difficulty. He had loved this woman so; and yet instinct suggested to me that she had been unworthy of his deep affection. That she had been untrue to him I did not know. Galimard might have stolen the jewels from her, and have replaced them with a false set; on the other hand, she might have been a party to the fraud. What, then, should I say, or how much should I dare with the great responsibility before me of crushing a man whose heart was already broken?

With such thoughts I re-entered the apartment in the Rue de Morny. As I did so, the servant put a telegram into my hand, and told me that M. Jules Galimard was with his master. Fate, however, seemed to have given the man another chance, for the cipher said,—

"Green and Co. in error, they should have sent the stones only; necklace not for sale; client's name unknown, acting for Paris agents."

I walked into the room with this message in my pocket; and when Brewer saw me he jumped up with delight, and introduced me to a well-dressed Frenchman who had the red rosette in the buttonhole of his faultless frock-coat, and who showed a row of admirable teeth when he smiled to greet me.
