Both Seigel and Gollowitz stared at him.

“You wouldn’t be kidding?” Seigel asked blankly.

Ferrari ignored him.

“It’ll be a nice smooth job,” he said, evidently very pleased with himself. “One of my best jobs.”

“How is it to be done?” Gollowitz asked in a hushed voice.

“I had to have inside help,” Ferrari explained. “That was essential. I have persuaded Sergeant O’Brien to help me.”

“O’Brien?” Gollowitz exclaimed, leaning forward. “But you can’t trust him. We’ve never got anywhere with him.”

Ferrari smiled.

“Maybe you didn’t find out his particular weakness. Everyone has a weakness. O’Brien has a son. He happens to be very fond of him. I have a son too, and I have learned that sons are precious to fathers: more precious sometimes than wives. A man likes to think that when he dies his name will be carried on. O’Brien is no exception. So he has agreed to help.”

“Well I’ll be damned!” Seigel exclaimed admiringly. “I didn’t even know he had a son.”
