Children can put their spy skills to the ultimate test in this fiendish puzzle activity book.

This book features tons of different spy scenarios to work through, with brain-boggling puzzles to crack. The reader is always at the centre of the action – in some stories they will be an experienced agent on a mission to defeat enemy insurgents, while in others they change sides, and become criminal geniuses creating chaos to achieve their evil ends. Can they crack the code to a safe full of secret plans? Or choose the route most likely to help them shake the agent who’s on their tail?

The puzzles drop children deep inside the world of international espionage and they will need all their logic and puzzle-solving skills to survive. Puzzles get harder as the book goes on – readers can crack the cases and work their way up from rookie to mastermind.
