When a large shipment of gold disappears en route to England, Sherlock Holme, knows that only one man is clever enough to pull off such an outlandish and theoretically impossible crime: Professor James Moriarty. Moriarty, however, had nothing to do with the crime, but to regain his peace he undertakes to locate the missing gold, and soon finds himself matching wits with a mind as nimble—perhaps even more so—than his own.
