Si the Spy is back in his third adventure! Can you uncover the bizarre Banana Conspiracy, and help him defeat the nefarious Sergeant Split? Find Si - and his friends and enemies - hiding out in all sorts of locations. But that's not all! There are also codes to crack, mazes to get through, and all kinds of fiendish (but not TOO fiendish) puzzles to solve. This book is designed to be enjoyed if you just want to find Si the Spy hiding on every page, or if you want to read it through to get the story and solve the puzzles. If you've read "Where's the Spy", you'll know what to expect, and you'll have already met our hero Si, his boss Spymaster Z, and his science-whiz buddy Professor Nyota - but this adventure stands entirely on its own, there's no need to read any other books in the series first!How difficult are the puzzles? Well, they're a littler tougher than 'Where's Spidey', but not as hard as 'Where's Wally'.
