Olympia case

This is a story about mathematical puzzles and also about the adventure of the daughter of Professor Theodore Voliffo and her granddaughter (the narrator), who is a university student in her twenties; and Piero, a clever ten-year-old boy; in order to uncover academic Olympic secrets. The author followed, through events full of excitement and walks through the streets and landmarks of Paris, the path of these three adventurers and the clues to solving some mathematical puzzles as a necessary condition for joining the Olympic Academy, which is credited to the founding of both Einstein and the grandfather Theodore Voliffo.
