The puzzles are arranged by level of difficulty and become progressively harder, so you can start with the (relatively) easy ones and build up to the truly expert level tests. It is designed to give the solver an unparalleled and hugely enjoyable challenge, and perhaps the chance to see if they might have been recruited to join the ranks of Alan Turing's codebreakers! It contains a range of different types of puzzles, and so presents a wonderfully entertaining challenge for any puzzle lover. The wide range of cryptic puzzles, accompanied by enigmatic clues as well as hints and step-by-step solutions, is compiled by world-renowned puzzle expert Dr Gareth Moore.

Often called the father of modern computing, the book is inspired by the genius of Alan Turing and proudly supports The Turing Trust, the charity set up by Turing's closest family in his memory. At the same time, this is the tragic account of a man who, despite his wartime service, was eventually arrested, stripped of his security clearance, and forced to undergo a humiliating treatment program-all for trying to live honestly in a society that defined homosexuality as a crime.This unique collection of fascinating codebreaking puzzles offers the ultimate test for a would-be code-cracking expert. The book also tells how this work was directly related to Turing’s leading role in breaking the German Enigma ciphers during World War II, a scientific triumph that was critical to Allied victory in the Atlantic. This New York Times–bestselling biography of the founder of computer science, with a new preface by the author that addresses Turing's royal pardon in 2013, is the definitive account of an extraordinary mind and life.Ĭapturing both the inner and outer drama of Turing’s life, Andrew Hodges tells how Turing’s revolutionary idea of 1936-the concept of a universal machine-laid the foundation for the modern computer and how Turing brought the idea to practical realization in 1945 with his electronic design.

It is only a slight exaggeration to say that the British mathematician Alan Turing (1912-1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades-all before his suicide at age forty-one.
