When science teacher Trevor Adams is offered the job as head of his subject at a private school in rural Dorset, he can't believe his luck. Having worked at the same urban comprehensive school for nearly a decade and having grown tired of the crime and social issues in his home town, the move to Dorset seems like the perfect opportunity for him and his growing family. Soon after the move, a great tragedy strikes, which leads to Trevor's teenage daughter Samantha going missing. Trevor instantly suspects his new neighbour, the socially inept and rather odd Mr Brooks, of being involved in her disappearance. Why does Trevor's neighbour go out into his garden in the middle of the night? Why do Mr Brooks's wife and daughter never seem to leave the house? And just what are the noises Trevor hears on the other side of the fence? With Trevor thinking one thing and the local police another, he can only turn to his brother-in-law, DS Jerome Roberts for help. Harriett Brown has been searching for her best friend's sister Chloe for five years, sacrificing a great deal in the process. Having made little progress in that time, she begins to wonder if it is time to move on. However, when she hears of Samantha's disappearance, she's desperate to know more. Samantha is just one of a dozen other girls who have gone missing from the area since Chloe. In this fast paced mystery, you soon learn that you can never really trust anyone, and you'll be guessing until the very end.
