TOP SECRET SPY PUZZLE BOOK (PB)

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