"Well, the Spaniard's easy to pick up," said Hallet. "I'll have him inside an hour—"

"One moment, please," interposed Chan. "To-morrow morning at nine o'clock the President Tyler return from Orient. No gambler myself but will wager increditable sum Spaniard waits on dock for Mr. Bowker. If you present no fierce objection, I have a yearning to arrest him at that very moment."

"Who—me?" grinned Chan. "With your gracious permission I would alter the picture. Stone walls are crumbling now like dust. Through many loopholes light stream in like rosy streaks of dawn."

THE STONE WALLS CRUMBLE

The stone walls were crumbling and the light streaming through—but only for Chan. John Quincy was still groping in the dark, and his reflections were a little bitter as he returned to the house at Waikiki. Chan and he had worked together, but now that they approached the crisis of their efforts, the detective evidently preferred to push on alone, leaving his fellow-worker to follow if he could.

He even considered several the investigation had not touched. Presently he came to Bowker. What did Bowker's reappearance mean?
