“After what you said about the Mafia,” Simon explained, “I couldn’t take any chances. Not even in police headquarters. It’d only take one tiny leak to blow the whole works. And that’d mean goodbye to Sue.”

Simon took out a cigarette and placed it between his lips. Then he took out his lighter and held it poised.

“Nothing.”

He lighted the cigarette.

Hudson Inverest’s features seemed to crumple from inside, as if he had received a physical blow. He sank slowly into a chair.

“Good God, man,” he cried shakily. “What are you saying?”

Inverest clasped his hands together as if to steady them.
