When 16-year-old Caitlin Reynolds fails to return home from school, Detective Inspector Sarah Quinn soon realizes this is no ordinary missing persons case. How could a schoolgirl vanish in broad daylight with no witnesses? Why is Caitlin's mother so unhelpful and hostile to the police?

To make matters worse, journalist Caroline King has got hold of the story – and Sarah Quinn's troubles are only just beginning.
