The Callender siblings, Lori, Joseph, Ahmed, and Elizabeth, children of famous archaeologists and members of the Sleuth Club, are truly clever kids: they don't believe what they're told unless they see it with their own eyes, they love puzzles and mysteries, they persist through difficulties, and they don't hesitate in the face of danger. The entire Callender family is invited to the Brooklyn Museum in New York City for an international senet tournament. Senet was the favorite board game of the pharaohs, and the final will be played with the original board of Amenhotep III. But who will compete in the final, and how will a simple game turn into a dangerous adventure in New York? You just have to find out!
