A game book with a unique concept on the children's publishing market: large double-page pages to fold which transform with each investigation for the pleasure of the reader who improvises as a detective.
Thirteen new puzzles: vampires, ghosts, skeletons, zombies, aliens, were-animals, running dinosaurs, giant insects, out-of-control robots, witches and evil dolls... This puzzle book is full of equally terrifying characters, situations and animals. How humorous!
Each puzzle asks questions and gives directions for progress. The reader solves his enigma thanks to the victims' testimonies and the observation of indoor and outdoor environments, after which he discovers the perpetrator.
