A Criminal Assignment

Wanting to catch other criminals, the British secret service gains the release of a counterfeiter who's dropped into France. He is to produce bills that contain a tiny flaw to be used to pay off the suspected double-dealers. With the plan a success, the ex-con is free to go. Following the war, the counterfeiter disappears and authorities find two perfect plates. Clearly, he couldn't resist the temptation to print a little for himself.
