There are some things that I am sure he cannot know."

"About Mayo, for instance?" Benson suggested.

"I don't think he knows that. I don't see how he could. But he may figure there's somebody else in this racket — somebody that's laying low. If he gets up to Greenhurst — "

"He may find out what Hawthorne knows, eh?"

"Exactly. That's why I want you to get up there, right away, with Grady," Delmuth said.

"Well," nodded Benson, "the sooner we pull the last job, the better. Leave it to me and Grady. We'll start tonight — now that everything else is out of the way."

"No," dissented Delmuth. "Don't do a thing until you hear from me, unless you find that The Shadow is mixing in it. Stay near Greenhurst, but not too close. I'll tip you off when to pull the job."

"I'm going to send Shamlin and Harmon up to work with you."

"Why?"

"Because this has got to look like a disappearance. No murder on the premises. There's ill feeling supposed to exist between Hawthorne and Mayo. If anything should happen to either one of them, the other will be blamed."
