X, Y & Z describes how French, British and Polish secret services came together to unravel the Enigma machine. It tells of how, under the very noses of the Germans, Enigma code-breaking continued in Vichy France. And how code-breakers from Poland continued their work for Her Majesty’s Secret Service, watching the USSR’s first steps of the Cold War.

Selected by Nature as one of the best books of 2018.

Listen to Dermot Turing talking to Polska Półka – the Polish Bookshelf Project about the contribution of Polish cryptographers to breaking the Enigma code, the meaning of their story in today’s world, and his latest book, “X, Y & Z: The Real Story of How Enigma Was Broken”.
