Would GCHQ recruit you? Pit your wits against the people who cracked Enigma in the official puzzle book from Britain's top secret intelligence and security organisation

In this book you will find:
- Tips on how to get into the mindset of a codebreaker
- Puzzles ranging in difficulty from easy to brain-bending
- A competition section where we search for Britain's smartest puzzler
With hundreds of stimulating puzzles, The GCHQ Puzzle Book is the perfect companion and will keep you occupied as you attempt to beat the smartest brains in Britain.
