"I've lost all I had on that infernal fan-tan of yours," shrieked Villiers, not heeding him; "but my luck must change--give me another fiver."

"Ah Goon no have," reiterated the Chinaman, edging away from the excited Villiers.

"Curse your no have," he said fiercely; "why, I've only had twenty pounds from you, and those diamonds were worth fifty."

Diamonds! Naball pricked up his ears at this. He was winning after all. Kitty did not steal her jewels, but this was the thief, or perhaps an accomplice.

"Give me more money," cried Villiers, lurching forward, and would have laid his hand on the shoulder of the shrinking Chinaman, when Naball stepped out of his corner.

"What's the matter?" he asked, in his silky voice.

Villiers turned on the new-comer with a sudden start, and stared suspiciously at him; but the detective being muffled up in a heavy ulster, with his hat pulled over his eyes, he did not recognise him.

"What do you want?" he said ungraciously.

"Nothing," replied Naball quickly. "I'm only strolling round the Chinese quarter out of curiosity, and heard you rowing this poor devil."

"Poor devil!" sneered Villiers, with a glance of fury at Ah Goon, who had complacently resumed his occupation of preparing an opium pipe; "he's rich enough."
