For this episode, Red is joined by Ben Macintyre, the award-winning author of over a dozen historical biographies that reveal some of the most fascinating and entertaining true spy stories of 20th-century history. From double agents operating during World War II to legendary Cold War spies such as Kim Philby and Oleg Gordievsky, Ben’s research has given him access to some of the most closely guarded secrets in the history of espionage. His outstanding biography of Operation Mincemeat, a daring scheme to misdirect the Nazis in 1943, was adapted into a feature film earlier this year. But Ben is not one to rest on his laurels; his latest book explores another remarkable corner of World War II operations. Prisoners of the Castle: An Epic Story of Survival and Escape from Colditz, the Nazis’ Fortress Prison, shines new light on one of the greatest war stories ever told. Join Ben and Red as they discuss tunnels, tradecraft, and the type of character required to be the perfect spy.
