Brush Pass with Bill Koenig. The long-running U.S. panel show To Tell The Truth had a panel trying to determine who of three people had performed some feat or had some career, etc. At least four times, the show had people who worked in intelligence. One was John Le Carre. Others were Eric Ericsson, who posed as a traitor in World War II and wrote a book called The Counterfeit Traitor. It was made into a movie starring William Holden. Others were Pawal Monat, a Polish spy who defected and the other was Eddie Chapman, who was a double agent for the British against the Nazis.
