THE TRIPLE HOAX
Nancy, Bess and George are called to New York by Aunt Eloise to help investigate the swindling of Mrs. Richards. The group attends magic show by the Hoaxsters where Bess volunteers to go on stage and has her handbag lifted. It is returned to her at the end of the show intact, but Nancy is suspicious that it has been searched. Show departs town suddenly, and girls decide to follow the potential con men to Mexico City, then later to Los Angeles. The girls meet Sra. Mendez at the Hoaxster show in Mexico; her grand-daughter Dolores is kidnapped soon after.
