“Twelve o’clock exactly,” said Willie.
“When did you get back?”
“Twelve-fifteen, exactly.”
“Was anybody in the office when you returned?”
“I did not see a soul, sir, except yourself.”
“What did you do between twelve-fifteen and one o’clock?”
“I was in the wireless room during every moment.”
“Can you prove it?”
“I—I—I don’t know, sir. Nobody saw me go in and nobody saw me come out. There was nobody in the office when I got back except yourself. I don’t think you saw me, sir.”
“No, I didn’t.”
