"I can't give it to you," Hallet answered. "You'll have to take my word for it."

"I've taken your word for a good many things," said John Quincy hotly. "This begins to look rather suspicious to me. Are you trying to shield somebody?"

Hallet rose and laid his hand on John Quincy's shoulder. "I've had a hard day," he remarked, "and I'm not going to get angry with you. I'm not trying to shield anybody. I'm as anxious as you are to discover who killed Dan Winterslip. More anxious, perhaps."

"Yet when we bring you evidence you tear it up—"

"Bring me the right evidence," said Hallet. "Bring me that wrist watch. I can promise you action then."

John Quincy was impressed by the sincerity in his tone. But he was sadly puzzled, too. "All right," he said, "that's that. I'm sorry if we've troubled you with this trivial matter—"

"Don't talk like that," Hallet broke in. "I'm glad of your help. But as far as Mr. Saladine is concerned—" he looked at Chan—"let him alone."

Chan bowed. "You are undisputable chief," he replied.

They went back to Punchbowl Hill in the roadster, both rather dejected. As Chan alighted at his gate, John Quincy spoke: "Well, I'm pau. Saladine was my last hope."

The Chinaman stared for a moment at the moonlit Pacific that lay beyond the water-front lamps. "Stone wall surround us," he said dreamily. "But we circle about, seeking loophole. Moment of discovery will come."
