Mysteries follow super-sleuth Cam Jansen everywhere she goes...even to her school's Sports and Good Nutrition Day. Cam's class is going to Franklin Park to run races, play soccer and baseball, and have a picnic lunch. Cam is ready for lots of sporting fun, but she doesn't expect a mystery--much less three of them! It's going to be on exciting day!

The Cam Jansen books are perfect for young readers who are making the transition to chapter books, and Cam is a spunky young heroine whom readers have loved for over two decades.
