Codebreakers

Bletchley Park was arguably the most successful intelligence agency in world history, the top secret workplace of the remarkable people who cracked Germany's vaunted Enigma Code. Almost to the end of the war, the Germans had firm faith in the Enigma ciphering machine, but in fact the codebreakers were deciphering nearly 4,000 German transmissions daily by 1942. Indeed, Winston Churchill hailed the work of Bletchley Park as the `secret weapon' that won the
war.

With anecdotes and descriptions, this is an account of daily life at Government Communications Headquarters, Bletchley Park, the most successful intelligence agency in history.

Anyone interested in the Second World War will sit up all night, and chess players and puzzle-solvers will be captivated by the later chapters.
