Since the secret of Bletchley Park was revealed in the 1970s, the work of its codebreakers has become one of the most famous stories of the Second World War. But cracking the Nazis' codes was only the start of the process. Thousands of secret intelligence workers were then involved in making crucial information available to the Allied leaders and commanders who desperately needed it.

The World War II codebreaking station at Bletchley is well known and its activities documented in detail. Its decryption capabilities were vital to the war effort, significantly aiding the Allied victory. But where did the messages being deciphered come from in the first place? This is the extraordinary untold story of the Y service, a secret even more closely guarded than Bletchley Park. 'Y service' was the code for the chain of wireless intercept stations around Britain and all over the world.

Between 1941 and 1945, more than eight hundred shiploads of supplies were delivered to the Soviet Union protected by allied naval forces. Each journey was a battle against the elements, with turbulent seas, extreme cold, and the constant dread of torpedoes. These Arctic convoys have been mythologized as defenseless vessels at the mercy of deadly U-boats—but was this really the case?

Planning the invasion of Normandy, the Allies knew that decoding the communications of the Nazi high command was imperative for its success. But standing in their way was an encryption machine they called Tunny (British English for “tuna”), which was vastly more difficult to crack than the infamous Enigma cipher.

The scene of unrelenting human ingenuity during World War Two, while the story of the decipherment of the Enigma codes and Alan Turing is celebrated in the movie the Imitation Game, less well known is what life was actually like for the thousands of women and men who worked at Bletchley Park under clandestine conditions. With access to Bletchley Park and contributions from historians and scientists Maggie Lee meets two remarkable people who worked at Station X, learning how the top secret work carried out here helped usher in the computer age and deepen the foundations of the UK's cyber and intelligence centre.
