Sally Sleuth, a fourth-grade self-proclaimed detective, is charged to bring the class's pet mice home for the evening. But with her brother's snake crawling around, her dad locking himself up in his office all night, and her mom's strict "time for bed" policy causing her to leave the mouse cage open, it's no wonder the animals have disappeared by the next morning.

Sally doesn't have much time to find the mice before she'll let her teacher and all her friends down.

Sally Sleuth is a series of chapter books for kids who like mysteries.
