Every sound in thirteen-year-old Jasper Wishart's world has its own unique color, from each person's individual voice to noisy birds to slamming doors. When Bee Larkham, the neighbor lady he watches from his window, disappears, Jasper sees the ice blue color of murder. Afraid that he's done something terrible to her, he begins to look back on their interactions that he's obsessively recorded in his notebooks to see if he can find any clues. But someone else doesn't want Jasper to find out the truth.
