Jericho races to break the new U-boat code while secretly investigating the stolen intercepts hidden by his missing lover.
In August 1939 Britain's Government Code and Cypher School moved to this Buckinghamshire estate. Building on Polish work, Alan Turing and Gordon Welchman designed the electromechanical bombe, which from 1940 broke German Enigma settings daily; Hut 8 attacked the naval traffic vital to the Atlantic convoys. By 1945 nearly 10,000 people worked there, and the Colossus computers were cracking Hitler's high-level Lorenz cipher.
