The most useless and obnoxious thing in the world to Caroline Tate is her older brother, J.P., the genius with the photographic memory. But now, for the first time, she needs him. She needs him because upstairs in the fifth floor apartment of their building is a mystery man who plans to commit a terrible crime-and she and J.P. are the targets! Luckily, Caroline's best friend, Stacy, wants to be an investigative journalist, so she knows how to gather evidence. Together, Caroline, Stacy, and J.P. set out to catch this criminal red handed before he can pull off his dastardly deed!

Eleven year old Caroline finds some letters belonging to the mystery man on the fifth floor that seems to show he's about to commit a terrible crime - and she and her brother are the targets.
