"So that's what our new gentleman has been doing, is it, sir?" demanded Mr. Costigan, his Irish quickness enabling him to guess much at the first glance.

"Have you handcuffs with you, Mr. Costigan?" asked Tom.

"I have, sir."

"Then put them on this fellow."

With a right good will Mr. Costigan and the sailor rolled Cragthorpe over, not very gently at that, and forced his wrists together, manacling the wretch. Then they dragged him to his feet.

"Jupiter!" muttered Tom, staring hard. "I've seen this fellow somewhere before. And now I have it! By Jove, he's the gallant fellow I had to knock from the observation platform on the Overland Mail!"

"You needn't be quite so glad. We haven't quite evened our account yet," snarled the fellow. "But I'm not the man you think I am."

"Do you deny you're the fellow I struck on the observation platform of a car of the Overland Mail the other day?" Tom Halstead snorted.

"I can't be. I've just come from Auckland," leered the fellow.

"We picked him up from a small boat that bore the name of the liner, 'Dolbear,'" interjected Mr. Costigan. "The 'Dolbear' is due about now from Auckland."
