The fighting has ended, the Armistice signed, but the war has left wounds that are still agonizingly raw. Battlefield Nurse Bess Crawford has been assigned to a clinic for amputees, and the Welsh patients worry her. She does her best to help them, but it's clear that they have nothing to go home to, in a valley where only the fit can work in the coal pits. When they are released, she fears that peace will do what war couldn't - take their lives.
Their officer, Captain Williams, writes to describe their despair, and his own at trying to save his men. Bess feels compelled to look into their situation, but the Army and the clinic can do nothing. Requesting leave, she quietly travels to Wales, and that bleak coal mining village, but she is too late.
Captain Williams' sister tells Bess he has left the valley. Bess is afraid he intends to kill himself. She follows him to an isolated, storm-battered peninsula - a harsh and forgotten place where secrets and death go hand in hand. Deserted by her frightened driver, Bess is stranded among strangers suspicious of outsiders. She quickly discovers these villagers are hiding something, and she's learned too much to be allowed to leave. What's more, no one in England knows where she is.
Why is there no Constable out here? And who is the mysterious Ellen? Captain Williams and his brother's widow are her only allies, and Bess must take care not to put them at risk as she tries to find answers. But there is a murderer here who is driven to kill again and again. And the next person in his sights is Simon Brandon, searching for Bess and unaware of his danger...
