When the bones of two severed hands are discovered in a box, an investigation into a long buried crime of passion begins. And a group of friends, who played together as children, begin to question their past. 'For Woody, anger was cold. Cold and slow. But once it had started it mounted gradually and he could think of nothing else. He knew he couldn't stay alive while those two were alive. Instead of sleeping, he lay awake in the dark and saw those hands. Anita's narrow white hand with the long nails painted pastel pink, the man's brown hand equally shapely, the fingers slightly splayed.' Before the advent of the Second World War, beneath the green meadows of Loughton, Essex, a dark network of tunnels has been dug. A group of children discover them. They play there. It becomes their secret place. Seventy years on, the world has changed. Developers have altered the rural landscape. Friends from a half-remembered world have married, died, grown sick, moved on or disappeared. Work on a new house called Warlock uncovers a grisly secret, buried a lifetime ago, and a weary detective, more preoccupied with current crimes, must investigate a possible case of murder.
