They know who did it. Perhaps not consciously. Perhaps not yet. But they know.

When eight-year-old Daisy Mason vanishes from her family’s Oxford home during a costume party, Detective Inspector Adam Fawley knows that nine times out of ten, the offender is someone close to home. And Daisy’s family is certainly strange—her mother is obsessed with keeping up appearances, while her father is cold and defensive under questioning. And then there’s Daisy’s little brother, so withdrawn and uncommunicative . . .

DI Fawley works against the clock to find any trace of the little girl, but it’s as if she disappeared into thin air—no one saw anything; no one knows anything. But everyone has an opinion, and everyone, it seems, has a secret to conceal.
