The clerk inspected the kettle, reached into his inside pocket, took out a roll of bills, and handed it over to the doctor. The roll contained exactly $500 — the clerk’s entire savings!

The doctor handed over a small slip of paper on which was written a secret formula. The words on that small slip of paper were worth a King’s ransom! But not to the doctor! Those magic words were needed to start the kettle to boiling, but neither the doctor nor the young clerk knew what fabulous fortunes were destined to flow from that kettle.
