“And follow your instructions of this morning?”

“To the letter.”

“I will. Have you any to add?”

“No. I shall wait for your next report.”

“Very good. You shall receive it as soon as possible,” Mack assured him. “I’m game, mind you, for whatever the case requires.”

“You are well chosen, then, for this work,” Nick replied. “Between us, I think we can turn the trick.”

“Me, too! So long.”

“Good-by and good luck.”

Nick hung up the receiver.

“By Jove, that dovetails well with Patsy’s report,” Chick declared, after Nick had told him of Mack’s statements. “The man with a figured vest must be the same Jack Conroy mentioned by Patsy, and the intimate friend of Kate Crandall. Both evidently are in this job, including Duffy’s wife and son, and very likely Duffy himself. What do you think?”
