Brewster's Millions by George Barr McCutcheon

Soon after noon on the 22nd of September, Monty folded his report to Swearengen Jones, stuck it into his pocket and sallied forth. A parcel delivery wagon had carried off a mysterious bundle a few minutes before. Mrs. Gray could not conceal her wonder, but Brewster's answers to her questions threw little light on the mystery. He could not tell her the big bundle contained the receipts that were to prove his sincerity when the time came to settle with Mr. Jones. Brewster had used his own form of receipt for every purchase. The little stub receipt books had been made to order for him and not only he but every person in his employ carried one everywhere. No matter how trivial the purchase, the person who received a dollar of Brewster's money signed a receipt for the amount. Newsboys and bootblacks were the only beings who escaped the formality; tips to waiters, porters, cabbies, etc., were recorded and afterward put into a class by themselves. Receipts for the few dollars remaining in his possession were to be turned over on the morning of the 23rd and the general report was not to be completed until 9 o'clock on that day.

He kissed Peggy goodbye, told her to be ready for a drive at 4 o'clock, and then went off to find Joe Bragdon and Elon Gardner. They met him by appointment and to them he confided his design to be married on the following day.
