“And I think I know with what,” he added, thinking aloud. “You have no idea, James, how long he had been in?”

“None at all, sir. I didn’t know he was in until you rang me up.”

“Nobody called, sir, but a lady rang him up.”

“A lady? At about what time?”

The man thought for a moment.

“As near as may be, I should say it was nine o’clock, sir.”

“Anybody you know? Did she give any name?”

“No, sir. It was not a voice I recognized.”

“Leave any message?”
