Listening to the Enemy is a fascinating story of the Bletchley Park outstation. Over several years, Mike Griffiths has painstakingly researched the origins and purpose of this site. His father, Harry, was a radio operator at the station throughout the war and he recorded many of his contacts in a little black nook – his ‘Code Book’. This book – full of German and Italian radio nets, brevity codes and Double Agent call signs, encapsulates the role of Bletchley Park; the home of the Codebreakers.
