This is Kathleen's fourth mystery for American Girl, and her nineth published book. It has consistently been one of her most popular. It is written for readers age 9 and up who enjoy stories about Kit Kittredge and her life during the Great Depression. 

Story Description

Kit Kittredge is back, in a mystery that takes place at the Cincinnati Zoo! Kit lands a summer job writing a children's column for her local newspaper and looks for story ideas at the Cincinnati Zoo where her friend Stirling works as a guide and her old friend Will, the hobo, has a job cleaning cages.

As Kit noses around, she stumbles into some strange activities in the monkey house. Meanwhile, Kit begins to notice small things missing at home too. It's not long before Will looks like the logical suspect in both places. Can Kit clear her friend--and get a good story in the bargain? Fireworks fly as Kit's mystery is solved at the zoo's grand Fourth of July spectacular.

This book includes a richly illustrated "Peak Into The Past" essay. The softcover and hardcover formats of this 192-page book are now out of print, but multiple eBook versions are still available for purchase.

Author's Note

Researching a novel can be hard work.  For this one, I had to spend a day visiting the Cincinnatti Zoo!  Don’t you feel sorry for me?  …No, I didn’t think so.

I chose to write a mystery that was partly set at a zoo because I love animals.  This is one of my bestselling books—so far, anyway—so I think lots of readers must love animals too!  This story is about more than fun times.  It’s about loyalty, and trust, and friendship.  It’s about a girl smart and brave enough to look for answers in times of trouble. Enjoy!
