GCHQ: The Uncensored Story of Britain's Most Secret Intelligence Agency

GCHQ is the successor to the famous Bletchley Park wartime code-breaking organisation and is the largest and most secretive intelligence organisation in the country. During the war, it commanded more staff than MI5 and MI6 combined and has produced a number of intelligence triumphs, as well as some notable failures. Here, Aldrich traces GCHQ's evolvement from a wartime code-breaking operation based in the Bedfordshire countryside, staffed by eccentric crossword puzzlers, to one of the world leading espionage organisations. It is packed full of dramatic spy stories that shed fresh light on Britain's role in the Cold War.
