GCHQ The uncensored story of Britain's most secret intelligence agency

'Thoroughly engaging' Daily Telegraph

'Skilfully weaves together the personal, political, military and technological dimensions of electronic espionage' Economist

'Aldrich packs in vast amounts of information, while managing to remain very readable. He paints the broad picture, but also introduces fascinating detail.' Literary Review

'Richard J. Aldrich is an outstanding analyst and historian of intelligence and he tells this story well...an important book, which will make readers think uncomfortably not only about the state's power to monitor our lives, but also the appalling vulnerability of every society in thrall to communications technology as we are.' Max Hastings, Sunday Times

'This is a sober and valuable work of scholarship, which is as reliable as anything ever is in the twilight world of intelligence-gathering. Yet there is nothing dry about it. Aldrich knows how to write for a wider audience, while avoiding the speculations, inventions, sensationalism and sheer silliness of so much modern work on the subject' Spectator
