"Do you know what all this is suggesting to me?" he exclaimed, nodding at Scarterfield. "Something happened on that ship! It may be that there was no shipwreck, as you said just now—something may have taken place of which we have no knowledge. But one fact comes out clearly—whether the Elizabeth Robinson ever reached any port or not, it's very evident—nay, certain!—that Noah and Salter Quick did. And—considering the inquiry he made at Lloyds—so did the Chinaman, Chuh Fen. Now—what could those three have told about the Elizabeth Robinson?"

No one made any remark on that, until Scarterfield remarked softly:

"I wish I had chanced to be at Lloyds when Chuh Fen called there! But—that's three years ago, and Chuh Fen may be—where?"

Something impelled Miss Raven and myself to glance at Dr. Lorrimore. He nodded—he knew what we were thinking of. And he turned to Scarterfield.

"I happen," he said, "to have a Chinaman in my employ at present—one Wing, a very clever man. He has been with me for some years—I brought him from India, when I came home recently. An astute chap, like——"

He paused suddenly; the detective had turned a suddenly interested glance on him.

"You live hereabouts, sir?" he asked. "I—I don't think I've caught your name?"

"I can vouch for him and his movements—I know where he was on the night of the murder. What I was thinking of was this—Wing is a man of infinite resource and of superior brains. He might be of use to you in tracing this Chuh Fen, if Chuh Fen is in England. When Wing and I were in London—we were there for some time after I returned from India, previous to my coming down here—Wing paid a good many visits to his fellow Chinamen in the East End, Limehouse way; he also had a holiday in Liverpool and another at Swansea and Cardiff, where, I am told, there are Chinese settlements. And I happen to know that he carries on an extensive correspondence with his compatriots. If you think he could give you any information, Mr. Scarterfield——"
