Burris appeared to think deeply. "I would celebrate," he said at last, in a judicious tone.

"I mean, would you just go on with the same crimes?" Malone said.

"What are you talking about, Malone?" Burris said cautiously.

"If you knew we'd arrested Brubitsch, Borbitsch and Garbitsch," Malone went on doggedly, "you'd lay off for a while, just to make us think we'd caught the right men. Doesn't that make sense?"

"Of course not," Malone said, feeling that something of the sort was called for.
