The names are changed, but the details of the crime are real. Scotland Yard detectives tell about a matter of theft when a mastermind has plans to rob a gold shipment.
Gold is routinely shipped through Heathrowe airport, but is the motorcade secure? Detectives are tipped off, but the strange warning from a man who claims to be poisoned make little sense. What does he mean? What does it have to do with a German prison camp? More clues emerge before all the puzzle pieces can be put together and make sense.
There’s a large syndicate behind the robbery. Will the detectives be able to think like their criminal and intercept the operation? Will they end up with the mastermind, or just a few henchmen?
