The Bedford Triangle portrays the crucial part played by the British Special Operations Executive, the US Army Air Force and the American Office of Strategic Services in operations behind enemy lines in occupied Europe during the Second World War. Milton Ernest Hall, a country house in Bedfordshire used officially as the UK headquarters of the US Army Air Force Service Command, was located at the heart of a network of top secret Allied Radio and propaganda transmitting stations, political warfare units and undercover British and American formations dealing in espionage and subterfuge.

Martin Bowman draws upon revealing first-hand accounts, together with official documentary evidence, to provide tantalising glimpses of cloak and dagger operations. The author's extensive research has revealed that Allied Secret Service organisations participated in even more unorthodox activities, such as clandestine propaganda and political warfare. He also reveals the truth about what really happened to legendary band leader Glenn Miller.
