The biography of Britain's leading wartime codebreaker by one of the top female codebreakers at Bletchley Park.

Alfred Dillwyn Knox was Britain’s leading wartime codebreaker, a famously eccentric and temperamental genius who cracked German ciphers in both wars. During the Second World War Knox became Britain’s chief cryptographer, working in a cottage at the world-famous Bletchley Park. His work would eventually provide the solution to German secret service Enigma cipher, ensuring the success of the 1944 D-Day landings.

A compelling portait of a great British eccentric and a fascinating and detailed behind-the-scenes look into codebreaking and the hidden side of war.
