It’s common knowledge that the Enigma cipher was broken at Bletchley Park, but less is known of the background: an exhilarating spy story of secret documents smuggled across borders, hair-raising escapes, Gestapo interrogations and betrayals.

At the heart of it is the decisive role of Polish mathematicians and French spymasters who helped Britain’s codebreakers change the course of the Second World War. X, Y & Z is the real story of how Enigma was broken.

Everyone knows the story of the codebreaker and computer science pioneer Alan Turing.

Except

When Dermot Turing is asked about his famous uncle, people want to know more than the bullet points of his life. They want to know everything was Alan Turing actually a codebreaker? What did he make of artificial intelligence? What is the significance of Alan Turings trial, his suicide, the Royal Pardon, the £50 note and the film The Imitation Game?

In Reflections of Alan Turing, Dermot strips off the layers to uncover the real story. Its time to discover a fresh legacy of Alan Turing for the twenty-first century.

'Turing writes on codebreaking with understandable authority and compelling panache.'
- Michael Smith, bestselling author of Station X.

At Bletchley Park, some of Britain's most talented mathematicians, linguists, and intellectuals were assembled to break Nazi codes. Kept secret for nearly thirty years, we have now come to realise the crucial role that these codebreakers played in the Allied victory in World War II.

Written by Dermot Turing - the nephew of famous codebreaker Alan Turing - this illustrated account provides unique insight into the behind-the-scenes action at Bletchley Park. Discover how brilliant and eccentric individuals such as Dilly Knox, Alan Turing and Joan Clarke were recruited, the social life that grew up around the park, and how they dealt with the ever-present burden of secrecy.

Including a foreword by Professor Christopher Andrew of Cambridge University, author of MI5's official history The Secret World, this book brings to life the stories of the men and women who toiled day and night to crack the seemingly unbreakable enigma code.

The Enigma cipher was supposed to be the German's impenetrable defence for its military communications against prying eyes during World War II. All manner of secrets were entrusted to it. When the Allies finally managed to crack the code, it heralded a turning point in the war.

This is the fascinating story of how the code was created, adopted by the Nazis, and finally broken. Dermot Turing, the nephew of the great codebreaker Alan Turing, explores the twists and turns of German encryption efforts from the end of World War I through to Hitler's demise and the great lengths to which the Allies went to break it.

The Enigma Story reveals the efforts of the codebreakers at Bletchley Park, the machines called 'bombes' specially designed to break it, and the vast resources devoted in America to decrypting German messages. From the cloak-and-dagger heroics of men like Hans-Thilo Schmidt and Gustave Bertrand to the brilliant mathematical discoveries of men like Henryk Zygalski and Dilly Knox to the fraught decision-making of Allied High Command, the battle for the code was at the heart of the Allied victory in World War II.

This extraordinary tale of intrigue, ingenuity and courage brings to life the complete story of the Enigma in a lively and entertaining narrative.

‘A cracking read. ’Nick Smith, Engineering and Technology

Alan Turing was an extraordinary man who crammed into his 42 years the careers of mathematician, codebreaker, computer scientist and biologist. He is widely regarded as a war hero grossly mistreated by his unappreciative country, and it has become hard to disentangle the real man from the story. It is easy to cast him as a misfit, the stereotypical professor. But actually Alan Turing was never a professor, and his nickname ‘Prof’ was given by his codebreaking friends at Bletchley Park.

Now Dermot Turing has taken a fresh look at the influences on his uncle’s life and creativity, and the creation of a legend. He discloses the real character behind the cipher-text, answering questions that help the man emerge from his legacy: how did Alan’s childhood experiences influence him? How did his creative ideas evolve? Was he really a solitary genius? What was his wartime work after 1942, and what of the Enigma story? What is the truth about the conviction for gross indecency, and did he commit suicide? In Alan Turing Decoded, Dermot’s vibrant and entertaining approach to the life and work of a true genius makes this a fascinating and authoritative read.

Today computers shape every aspect of our lives. In our pockets, we carry mobile phones with computing power that was unimaginable just 50 years ago. Many industries are embracing the promises - and the risks - of artificial intelligence. The world is changing faster than ever, and computing is at the heart of technological development.

Dermot Turing explores the history of this rapidly evolving technology, from the Charles Babbage and his experiments with steam powered calculators to the computerised Go champion, AlphaGo. Featuring wonderful, full-colour images which illustrate this history, The Story of Computing is the essential guide to a subject that none of us can ignore.
