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.

An authoritive and well researched history of GCHQ
Although this is a comprehensive history of GCHQ, it is also an easy read. Plenty of photographs too. GCHQ is often the more overlooked member of the three security services with Mi5 the Security service and Mi6 Secrey Intelligence Service. Yet GCHQ is perhaps the one that has the main influence for the general public. In addition to its intelligence gathering it also fights cyber attacks and protect our increasingly cyber dominated life. I thought I was already informed about the work of GCHQ and its NCSC (National Cyber Security Centre), but learnt a great deal from reading this book, realising my existing knowledge was rather limited.

Cryptologic must read.
A true must read for those that follow the crypto world. Well researched. Well written. Furst person accounts. Impeccable interpretations.
