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 the super spy at the centre of the action who needs to complete various missions, from defeating enemy insurgents to decoding case files. Can they crack the code to a safe full of secret plans? Or work out how their drone has been tampered with? Or choose the route most likely to help them shake the rogue 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.
