Lyne murdered! It was an extraordinary coincidence that he had been brought into touch with this young man only a few days before.

Tarling knew nothing of Lyne's private life, though from his own knowledge of the man during his short stay in Shanghai, he guessed that that life was not wholly blameless. He had been too busy in China to bother his head about the vagaries of a tourist, but he remembered dimly some sort of scandal which had attached to the visitor's name, and puzzled his head to recall all the circumstances.

He put down the newspaper with a little grimace indicative of regret. If he had only been attached to Scotland Yard, what a case this would have been for him! Here was a mystery which promised unusual interest.

His mind wandered to the girl, Odette Rider. What would she think of it? She would be shocked, he thought—horrified. It hurt him to feel that she might be indirectly, even remotely associated with such a public scandal, and he realised with a sudden sense of dismay that nothing was less unlikely than that her name would be mentioned as one who had quarrelled with the dead man.

"Pshaw!" he muttered, shrugging off the possibility as absurd, and, walking to the door, called his Chinese servant.

Ling Chu came silently at his bidding.

"Ling Chu," he said, "the white-faced man is dead."

Ling Chu raised his imperturbable eyes to his master's face.

"All men die some time," he said calmly. "This man quick die. That is better than long die."

Tarling looked at him sharply.
