“You were wise not to,” Jack agreed.
“I’m glad you think so,” Bob assured him. “You see we don’t know for sure just how he stands and until we do we’ve got to be mighty careful. Not that I think he’s mixed up in it but, of course, there’s a chance.”
“You going to sit up tonight?”
“Not for all the ghosts this side of—of—”
“Of where?”
“Well, I guess I don’t know,” Bob laughed. “But it’s me for the hay.”

“I promise. What is it?”
