"I got on the track of this craft—I'll tell you how, later—and found she'd come up this coast, and we got the authorities to send this destroyer after her—I came with her, hell for leather, I can tell you, from Harwich. But I don't know a lot that I want to know, Baxter, now—you're sure that man lying dead there is the Baxter we heard of at Blyth and traced to Hull?"

"Certain!" said I. "Listen, and I'll give you a brief account of what's happened since yesterday, and of what I've learned since then—it will make things clear to you."

Standing there, where the beauty of the fresh morning and the charm of sky and sea made a striking contrast to the horror of our immediate surroundings, I told him, as concisely as I could, of how Miss Raven and myself had fallen into the hands of Netherfield Baxter and the Frenchman, of what had happened to me on board, and, at somewhat greater length, of Baxter's story of his own career as it related to his share in the theft of the monastic treasure from the bank at Blyth, his connection with the Elizabeth Robinson and his knowledge of the brothers Quick. Nor did I forget Baxter's theory about the rubies—and at that Scarterfield obviously pricked his ears.

"Now there's something in that," he said, with a regretful glance at the place where Baxter's dead body lay under its sheet. "I wish that fellow had been alive, to tell more! For he's right about those rubies—quite right. The Quicks had 'em—two of 'em."

"You know that?" I exclaimed.

"I'll tell you," he answered. "After we parted, I was very busy, investigating matters still further in Devonport and in London. And—through the newspapers, of course—I got in touch with a man who told me a lot. He came to headquarters in London, asking for me—wouldn't tell any of our people there anything—it was a day or two before I got at close quarters with him, for when he called I was away at the time. He left an address, in Hatton Garden—a Mr. Isidore Baubenheimer, dealer, as you may conclude, in precious stones. Well, I drove off at once to see him. He told me a queer tale. He said that he'd only just come back from Amsterdam and Paris, or he'd have been in communication with me earlier. While he'd been away, he said, he'd read the English newspapers and seen a good deal about the two murders at Saltash and Ravensdene Court, and he believed that he could throw some light on them, for he felt sure that either Noah Quick or Salter Quick was identical with a man with whom he had not so long ago talked over the question of the value of certain stones which the man possessed. But I'll show you Baubenheimer's own words—I got him to make a clear statement of the whole thing and had it taken down in black and white, and I have a typed copy of it in my pocket-book—glance it over for yourself."

He produced a sheet of paper, folded and endorsed and handed it to me—it ran thus:

My place of business in Hatton Garden is a few doors away from the Hatton Garden entrance to the old Mitre Tavern, which lies between that street and Ely Place. On, as far as I can remember, the seventh or eighth of March last, I went into the Mitre about half-past eleven o'clock one morning, expecting to meet a friend of mine who was often there about that time. He hadn't come in—I sat down with a drink and a cigar to wait for him.

In the little room where I sat there were three other men—two of them were men that I knew, men who dealt in diamonds in a smallish way. The other was a stranger, a thick-set, middle-aged, seafaring sort of man, hard-bitten, dressed in a blue-serge suit of nautical cut; I could tell from his hands and his general appearance that he'd knocked about the world in his time. Just then he was smoking a cigar and had a tumbler of rum and water before him, and he was watching, with a good deal of interest, the other two, who, close by, were showing each other a quantity of loose diamonds which, evidently to the seafaring man's amazement, they spread out openly, on their palms.

After a bit they got up and went out, and the stranger glanced at me. Now I am, as you see, something of the nautical sort myself, bearded and bronzed and all that—I'm continually crossing the North Sea—and it may be he thought I was of his own occupation—anyway, he looked at me as if wanting to talk.
