Uncomfortably Christopher nodded.

"Well, that's what I am, you see," continued the man who had now regained his former debonnaire manner, "so the next time look out and don't be taken in. There are gentlemen who are thieves, sonny, and then again there are thieves who are gentlemen—at least I hope so."

So unruffled was his temper, so brave the front he put on the inevitable, that as Christopher saw him led away between two guards a momentary pang of regret passed over him. If Stuart had only happened to have turned his talents to some profession besides diamond stealing, what a delightful acquaintance he might have proved.

But the next instant Corrigan, the head inspector, broke in on this reverie, and his words banished further repining:

"The scoundrel won't open his lips," declared he to Mr. Burton. "What he's done with those diamonds we can't find out. He's mum as an oyster. I hoped we might tempt him into making a clean breast of the matter—but not he! He's too hardened a chap for repentance, I reckon."

"His pal, Tony, may have them."

"No doubt," acquiesced the chief. "The two probably have a cache where they stow their loot."

"I wish we could find it."

"So do I, with all my heart. We may, too, if we succeed in running down the other chap," Corrigan returned. "I shan't give up hope with Mr. Christopher on the job."

"I fancy my son isn't going into the business of tracking down criminals permanently," Burton, Senior, retorted a bit stiffly.
