"Warm, appealing, and cleverly devised." --Booklist 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!
