This is book number 28 in the Cam Jansen series.


No mystery is too great for super-sleuth Cam Jansen and her amazing photographic memory!

Mysteries follow super-sleuth Cam Jansen everywhere she goes...even to the school Green Day assembly. For each can and bottle Cam and her classmates brought in to be recycled, the school has earned a nickel. But when it is time to count the money, all the rolls of coins go missing. Can Cam find the not-so-green thief? 

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.
