“All the same, Chick, he is the man behind the gun in this job,” Nick said confidently. “He has got back at Waldmere for that other affair in which he was put on the rocks?”

“By Jove, the case seems to be shaping up.”

“It is shaping up to that extent,” Nick went on. “But Floyd is much too keen and cautious to have figured openly in this robbery with such a girl as Minerva Grand. There is a go-between, either a girl friend, or a lover. That’s who we must find and get after.”

“By Jove, I guess you are right,” Chick said, more gravely.

“Sure thing!” put in Patsy.

“We will take that chance,” Nick replied. “It is nearly a safe gamble, too, that Floyd, after holding up McLauren as a pretended detective, waited only for Bug Bannon to show up before he would release the truckman.”

“That’s how I sized it up,” Chick agreed.

“You think Bannon is in the job, chief?” questioned Patsy, who had lost part of what had been said in Waldmere’s library.

“I do, Patsy.”

“In what way?”
