“At what time?”
“At approximately five minutes to twelve. I happened to look at the clock at the time.”
“Did he say where he was?”
“No, he didn’t. He said he expected to arrive at the office during the first part of the afternoon, and I happened to notice the time when he was telephoning because I’d had rather a busy morning and had more or less lost track of time.”
“What time was it?”
“Almost exactly five minutes of twelve. I think it was about five and one-half minutes.”
“By an office clock?”
“Yes.”
“You’ve checked that office clock since?”
“Yes, it’s an electric clock. It’s absolutely right to the second.”
