In the crisp early morning hours, the police are called to a suspected murder at a farm outside a small English village. A beautiful young woman has been found dead, blood all over the cottage she lives in. At the same time, police respond to a reported female suicide, where a car has fallen into a local quarry. As DCI Louisa Smith and her team gather the evidence, they discover a link between these two women, a link which has sealed their fate one cold night, under a silent moon.
