In ancient Egypt a precious papyrus reveals the hiding place of a legendary scroll. Prince Setne Khaemwaset uses its secrets to create the magical collar of the seven ankhs. The ankhs are stolen, and a riddle is set that will disclose their locations. Ramose, a Time Lord, travels to the twentieth century to locate the riddle. One piece is in the Cairo Museum, and the other belongs to Vida Richardson Hardy in England. Her granddaughter Meri copies this fragment, and discovers a recipe for a magic mirror. Kenneth, Vida's grandson, identifies the second half of the riddle in Cairo. On a visit to London, he and Meri de-code the riddle, and venture back in time to Ancient Egypt to search for the seven ankhs. But Kenneth realizes that Meri's in danger - with the aid of the magic mirror, he goes to the rescue - but will he be able to save her?
