## Description

You know about MI5. You know about MI6. Now discover the untold stories behind Britain's most secretive intelligence agency, in the first ever authorised history of GCHQ. For a hundred years, GCHQ - Government Communications Headquarters - has been at the forefront of innovation in national security and British secret statecraft. Famed for its codebreaking achievements during the Second World War, and essential to the Allied victory, GCHQ also held a critical role in both the Falklands War and Cold War. Today, amidst the growing threats of terrorism and online crime, GCHQ continues to be the UK's leading intelligence, security and cyber agency, and a powerful tool of the British state. Based on unprecedented access to classified archives, Behind the Enigma is the first book to authoritatively tell the entire history of this most unique and enigmatic of organisations - and peer into its future at the heart of the nation's security.

Ouvrage majeur sur le sujet...
