Cam Jansen and the Millionaire Mystery Reprint edition

Can Cam catch a jewel thief?

Mysteries follow super-sleuth Cam Jansen everywhere she goes? even to a charity event. Cam and Eric are at a benefit with their mothers to raise money for local firefighters. When the host's pearl necklace goes missing, the luncheon turns into a whodunit, and all the guests are suspects. Can Cam use her photographic memory to identify the culprit before the thief gets away?
