I cannot say enough good things about this book! It tells the story of A., who inherits a mansion from his American cousin and decides to take up residence there with his friend in order to solve the mystery of his cousins mysterious suicide. The story is told through varied media forms - letters, transcripts, closed circuit cameras, etc. The story twists and turns as clues are discovered that lead to the grand finale. Oh, did I mention the book involves a secret society and ancient artifacts? So much fun!
