Cam Jansen: the Mystery of the Monkey House #10

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 zoo. When a few monkeys suddenly go missing from their cage, Cam is sure she knows how the thief took them. Can she find the missing monkeys before they are lost forever? 

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.
