In 1940, almost a year after the outbreak of the Second World War, Allied radio operators at an interception station in South London began picking up messages in a strange new code. Using science, maths, innovation and improvisation Bletchley Park codebreakers worked furiously to invent a machine to decipher what turned out to be the secrets of Nazi high command. It was called Colossus. What these codebreakers didn't realize was that they had fashioned the world's first true computer. When the war ended, this incredible invention was dismantled and hidden away for almost 50 years. Paul Gannon has pieced together the tremendous story of what is now recognized as the greatest secret of Bletchley Park.

Review quote

"* 'Paul Gannon has revealed a previously untold story... Colossus tells of the heroic efforts of the inventors and mathematicians who received no recognition for decades... but Gannon sets the record straight.' Simon Singh, The Times * 'Masterly in its breadth and sweep... His account of wartime interception and encryption is deeply researched... I commend the book to both the professional and the general reader.' Spectator"
