The Alan Turing Cryptic Codebreaking Puzzle Book Foreword by Sir Dermot Turing

Alan Turing is often called the father of modern computing. During the Second World War, he worked at Bletchley Park, where top secret work was carried out to decipher the military codes used by Germany and her allies. Turing played a pivotal role in cracking intercepted coded messages, so enabling the Allies to defeat the Nazis in many crucial engagements, and his work was vital in helping the Allies win the war. Published in association with The Turing Trust, this incredible collection of codebreakers allows you to test your own skills - if you can solve every puzzle in the book you might once have been recruited to join the ranks of Alan Turing's codebreakers! It contains a breath-taking range of different types of puzzles, and so presents a wonderfully entertaining challenge for any puzzle lover. 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. The Turing
