Overview
This two-book paperback set brings together The GCHQ Puzzle Book and its sequel The GCHQ Puzzle Book II, both compiled by the real codebreakers at Britain's intelligence agency, GCHQ. Packed with logic puzzles, ciphers, riddles and lateral-thinking challenges of genuinely varying difficulty, this collection is ideal for puzzle enthusiasts, trivia lovers, and anyone who enjoys testing their brainpower. A brilliant gift for adults and older teens who love a proper mental workout.

About the Books
The GCHQ Puzzle Book was the surprise bestseller that introduced the public to the kind of puzzles used to train and test the country's top codebreakers. Drawing on Bletchley Park heritage and modern cryptographic thinking, it mixes number puzzles, wordplay, logic grids and cipher-cracking exercises, with tips on adopting a codebreaker's mindset along the way. Suitable for beginners and seasoned solvers, it eases readers in with approachable challenges before ramping up the difficulty.

The GCHQ Puzzle Book II follows up with an entirely fresh set of puzzles, again devised by GCHQ's puzzle-setters. Structured to welcome newcomers with plenty of starter puzzles, it builds steadily towards trickier sections and a notorious 'Even Harder' chapter for veteran puzzlers. Published to mark GCHQ's centenary, this second volume also weaves in stories, facts and photographs charting the organisation's hundred-year history — from the Government Code & Cypher School and Bletchley Park through to modern cyber-security work — adding fascinating real-world context to the puzzles themselves.

• Authentic puzzles: Genuine codebreaking-style challenges devised by GCHQ's own puzzle-setters.
• Progressive difficulty: Starter puzzles through to an 'Even Harder' section for experienced solvers.
• Two full books: Both volumes included, each with hundreds of pages of fresh content.
• Brand new paperbacks: Perfect for gifting, travel, or building a puzzle library.
• Historical insight: Book II includes stories and photos from GCHQ's centenary history.
• Skill-building: Sharpens logic, lateral thinking, pattern recognition and cipher-cracking ability.
