Si the Spy is back in his second adventure! Find Si - and dastardly villain Professor Porcupine - 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. Can YOU help Si the Spy uncover the secret of the Porcupine Plot, and save the day?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 book one first!
