"Good morning, Whatsup," he said, without turning his head. "I'm glad to notice that you've had your house fitted up with electric lights at last."
"Will you please tell me," I said, in surprise, "how you knew that? I am sure that I never mentioned the fact to any one, and the wiring was a rush order not completed until this morning."
"Nothing easier," said Jolnes genially. "As you came in I caught the odour of the cigar you are smoking. I know an expensive cigar; and I know that not more than three men in New York can afford to smoke cigars and pay gas bills, too, at the present time. That was an easy one. But I am working just now on a little problem of my own."
"Why have you that string on your finger?" I asked.
"That's the problem," said Jolnes. "My wife tied that on this morning to remind me of something I was to send up to the house. Sit down, Whatsup, and excuse me for a few moments."
