Garry, struggling, was hoisted upward; his body revolved in mid-air and landed flat on the floor. The gangster lay stunned.

The victor did not hesitate. His robe slipped from his body. A folded mass of black cloth fell upon the floor beside the unconscious gangster.

The ex-Chinaman leaned over the form of Garry Elvers, scrutinizing the victim’s features. There, in that weird, dim room, an amazing transformation was taking place.

Moose Shargin, at that precise moment, was sitting in a little office on the balcony at the rear of the Manchu Restaurant. He had been ushered there by Looey Look, for whom he had inquired. The restaurant manager had just returned from his trip with Garry Elvers when Shargin arrived.

Wing Toy had not yet appeared. Hence Moose was alone with his thoughts, in the plainly furnished office. He sat in a chair and stared at a metal plate on the wall, above the telephone.

There were several small electric bulbs on the plate; One of them was lighted. Moose wondered what it meant. He waited several minutes. Then he heard a noise at the door, and Wing Toy entered.

“We shall wait here,” said the Tong leader, seating himself opposite Moose.

The gang leader was about to speak when Wing Toy suddenly noticed the light on the wall plate. For once the placid Chinaman registered surprise.

“That light!” he exclaimed. “When did it turn on?”

“It’s been on,” replied Moose.
