At first he maintained the sulky know-nothing role which he had adopted successfully with the official interpreter. Furneaux, watching the faces of prisoner and questioners, guessed that small progress was being made, so, waiting until Len Shi was evidently quite satisfied with himself, he suddenly thrust an ivory skull before the man's eyes. The result was unexpected but puzzling. The man was badly scared, beyond doubt, but he now became obstinately silent.

Winter, than whom no living actor could play up better to Furneaux's tactics in a touch-and-go encounter of this sort, assumed a highly tragic air.

"Handcuff that man, and bring him out!" he said to the constable in charge of the cells.

Len Shi blanched. He estimated the legal methods of Great Britain by those which obtained in his own land, and probably thought he was being led forth to immediate execution.

The whole five crowded into the car, and the driver, the same English chauffeur to whom Theydon had spoken, was told to make for 412 Charlotte Street, and pass the house slowly, but not pull up. Len Shi, though quaking with alarm, bore himself with a certain dignified stoicism until he found out where the car was apparently stopping. Then he said something in a panic-stricken voice and the jute merchant, who spoke English fluently, turned to Furneaux.

"Tell the chauffeur to return," he said. "Len Shi will now confess."

Once started, Len Shi talked volubly. The others merely put in a question now and then, and the detectives curbed their impatience as best they might until Len Shi was safely lodged in Bow Street again.

Then Winter led his Chinese helpers into an inner office and closed the door.

"Well?" he said, addressing the jute merchant. The other Chinaman had very little English and could not maintain a conversation.

But, to the chief inspector's surprise and wrath, the English-speaking Chinaman had only a request to make.
