"If the latter is the case," reasoned Nick, "the gang may stand in fear of me, and perhaps are afraid that I shall foil some scheme they have in operation, or are about to undertake. Then they to-night may have aimed only to discover the extent and nature of my suspicions.

"If that is the case, plainly it will become me to be a little foxy. I will see if I can contrive to overhear anything from out yonder."

"Look again, one of you," she curtly commanded. "See if that vagabond has come to himself."

"That's your humble servant!" thought Nick.

He quickly rolled back to his former position on the floor, and prepared to play the fox.

"I say!" he harshly growled, shaking Nick roughly by the shoulder. "Brace up, you dog! Brace up, d'ye hear?"
