The Spies of Winter

Following on from the enormous success of his bestseller, *The Secret Life of Bletchley Park*, Sinclair McKay now uncovers the story of what happened after the Second World War was over. Many of the men and women who had worked at Bletchley Park moved on to GCHQ, the British government's new facility established to fight a new foe - Stalin's KGB. McKay has interviewed various members of this secret organisation, from codebreakers and radio listeners to mechanical engineers and computer programmes who all shared the common desire to build a new Britain and protect it throughout the Cold War.
