The true story from the nephew of Alan Turing

Based on original research and recently released documents, "X, Y & Z: How the Enigma code was broken" is the fascinating story of the people who risked their lives to safeguard the greatest secret of World War II.

In the bathroom of a Belgian hotel, a French spy photographs highly classified documents - the operating instructions of the Enigma encryption machine. A few weeks later, a mathematician in Warsaw begins decrypting the encoded transmissions of the Third Reich and lays the foundation for the decryption operation at Bletchley Park. The collaboration between France, Britain, and Poland is codenamed "X, Y & Z".
