“I can’t do that,” Mason said.

“Why not?”

“Because it would betray the confidences of a client.”

“Do you deny that Robert Peltham called on you sometime between midnight and one o’clock on Tuesday morning?”

Mason said, “I’m not going to give you any information whatever concerning the activities of any client.”

“Under the circumstances,” Berger said, “I consider the interview closed. I have evidence which proves conclusively that Peltham was in love with Tidings’ wife, that Tidings refused to grant a divorce, and that while the affair had been kept successfully from his knowledge for some little time, he had finally learned about it and sought to trap the participants. It was while he was so engaged that he met his death.”

“When?”

“At eleven-fifteen Monday night.”

Mason spent several seconds staring at the smoke which eddied upward from the tip of his half-smoked cigarette. “At eleven-fifteen,” he said musingly.

“That’s right.”
