"Do not talk at meals. Do not talk in the transport. Do not talk travelling. Do not talk in the billet. Do not talk by your own fireside. Be careful even in your Hut." The 1942 security warning issued to staff at Bletchley Park was not paranoia -- it was survival. If Germany had discovered that the Allies were reading its encrypted communications, the entire advantage would have been lost. So nearly 9,000 people, at the peak of operations in January 1945, came to work at a Victorian country estate in Buckinghamshire, broke some of the most sophisticated ciphers ever devised, and told nobody. Churchill called them "the geese that laid the golden eggs and never cackled."

The estate was purchased in 1938 by Admiral Sir Hugh Sinclair, head of the Secret Intelligence Service, using 6,000 pounds of his own money because the government said it lacked the budget. Sinclair and his colleagues inspected the site under the cover of "Captain Ridley's shooti...

The German Enigma machine produced encrypted messages of extraordinary complexity, but it was not invulnerable. Polish mathematicians Marian Rejewski, Jerzy Rozycki, and Henryk Zygalski had broken earlier versions of Enigma before the war, and their work provided a crucial founda...

The Lorenz SZ42 cipher machine, used for high-level German military communications, was even more complex than Enigma -- a twelve-rotor system that Bletchley codenamed "Tunny." The cryptanalysts in the Testery worked out the machine's logical structure without ever seeing one, an...

Three-quarters of Bletchley Park's staff were women, drawn from middle-class backgrounds, many holding degrees in mathematics, physics, and engineering. They performed the calculations, operated the machines, and decoded the signals. Joan Clarke was one of the few employed as a f...
