The Egyptian Jukebox by Nick Bantock
In this picture-cum-puzzle book, every picture is full of clues which are designed to lead to the whereabouts of Hamilton Hasp, an eccentric millionaire who has disappeared. The drawers of his Egyptian jukebox each contain objects from a specific geographical location and have a corresponding story from Hasp's life. Nick Bantock also wrote "Griffin and Sabine", "Sabine's Notebook" and "The Golden Mean".
