It was Lorrimore who, at the detective's request, explained to Wing why we had sent for him. The Chinaman nodded a grave assent when reminded of the Salter Quick affair—evidently he knew all about it. And—if one really could detect anything at all in so carefully-veiled a countenance—I thought I detected an increased watchfulness in his eyes when Scarterfield began to ask him questions arising out of what Lorrimore had said.

"There is evidence," began the detective, "that this man Salter Quick, and his brother Noah Quick, were mixed up in some affair that had connection with a trading steamer, the Elizabeth Robinson, believed to have been lost in the Yellow Sea, between Hong-Kong and Chemulpo, in October 1907. On board that steamer was a certain Chinaman, who, two years later, turned up in London. Now, Dr. Lorrimore tells me that when you and he were in London, some little time ago, you spent a good deal of time amongst your own people in the East End, and that you also visited some of them in Liverpool, Cardiff, and Swansea. So I want to ask you—did you ever hear, in any of these quarters, of a man named Chuh Fen? Here—in London—two years after the Elizabeth Robinson affair—that's three years back from now."

The Chinaman moved his head very slightly.

"No," he answered. "Not in London—nor in England. But I knew a man named Chuh Fen ten, eleven, years ago, before I went to Bombay and entered my present service."

"Where did you know him?" asked Scarterfield.

"Two—perhaps three places," said Wing. "Singapore, Penang, perhaps Rangoon, too. I remember him."

"What was he?"

"A cook—very good cook."

"Would you be surprised to hear of his being in England three years ago?"

"Not at all. Many Chinamen come here. I myself—why not others? If Chuh Fen came here, three years ago, perhaps he came as cook on some ship trading from China or Burma. Then—go back again."
