Code-Breakers: Bletchley Park's Lost Heroes

Keeley Hawes narrates the story of how mathematician Bill Tutte and GPO engineer Tommy Flowers unravelled the secrets of Adolf Hitler's personal code machine - reputedly even more secure than the Enigma device. The duo's work played an important role in ending the conflict in Europe, but because of its classified nature and continued application during the Cold War, the two men were never officially recognised

Code-Breakers: Bletchley Park's Lost Heroes airs on BBC Four HD at 1:35 AM, Wednesday 18 June. (Subtitles, audio description.)
