The World Tour Mystery takes readers on a twelve stop trip to monuments, sites and wonders of the world with a lively family of six. But that's not all. There's some detective work to be done. Gentle hints in the diary jottings of the travellers and helpful clues in the spectacular pictures invite readers on every double spread to guess where the family's just been and no, it's not to the place on the previous double spread! the pictures not only capture the uniqueness of each man-made wonder but also draw readers to observe closely and think in logical sequence.
