Alan Turing is often called the father of modern computing. During World War II, he worked at Bletchley Park, where top secret work was carried out to decipher the military codes used by Germany and its allies. Turing played a pivotal role in cracking intercepted coded messages that enabled 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 puzzles allows you to test if you have the range of puzzle-solving abilities required to have been one of Alan Turing's codebreakers. World-renowned puzzle expert Dr. Gareth Moore compiled the work of puzzle authors from all over the world to bring together this fascinating collection of puzzle types.

If you can solve every puzzle in the book, you may once have been recruited to join their ranks!
