On the beaches and cliffs of North Devon, lone women have become victims in a terrifying game where only one player knows the rules. And when those rules change, the new game is murder. But a madman on the loose feels very far from the crumbling, seaside home of ten-year-old Ruby Trick. Instead she lives in constant fear of school bullies, the dark forest crowding her house into the sea, and the threat of her parents’ divorce. Helping her father to catch the killer seems like the only way to keep him close. As long as the killer doesn’t catch her first.
