Kit Kittredge is back, in a mystery that takes place in 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. Includes a full-color "Looking Back" historical essay.
