Just before D-Day in 1944, on the Isle of Purbeck in Dorset, an elderly woman walks into a police station. She has information, she says, about human remains recently discovered nearby. The bodies could have stayed buried for ever – like the love and the hatred that put them there. But Mary Holmes is finally ready to tell her story. The young constable sent to take her statement is still suffering from the injuries that ended his army career. As he tries to make sense of her tale, William finds himself increasingly distracted. Mary’s confession forces his own violent memories to the surface – betrayals and regrets as poorly healed as his war wounds.
