“Yes,” he said, “I can fix it to the minute, but I can’t do it offhand.”

“Why? How can you fix it, then?”

“Just as Low came to the desk a telegraph boy came with a message for a guest. I had to sign the boy’s book.”

“Yes. Well?”

“I had to enter the time, you know, and I looked up at the clock as I did so.”

“Did you enter the exact minute?”

“I did.”

“What was it?”

“That I can’t remember.”
