The flash of colour is what Sandy sees first – a red jacket, vivid against the snow on the hillside. She rushes forward, her breath catching in the cold air. The woman’s eyes are open and her mouth is taped shut, silencing her forever. And the baby carrier beside her is empty.

Detective Sandy Gray’s fresh start in the Scottish Highlands is shattered during her first week, when she must solve a terrible murder. Kate was one of their own – part of the mountain rescue team Sandy is leading and a young mother. And someone has taken her eighteen-month-old daughter, Isla.

As Sandy and her team launch a desperate search across the frozen landscape, she knows they are working against time. Then Sandy uncovers a note left with Kate’s body: This is the first of the silent girls to die. She will not be the last. The words send cold shivers through Sandy. Who are the silent girls, and why does someone want them dead?

When a second woman is discovered dead in the freezing river, bearing the same note, Sandy realises she’s hunting a murderer with a list – but why? With Isla still missing, the weather closing in and the mystery of why her own father turned his back on these hills haunting her, Sandy must push herself harder than ever to unravel a web of secrets in time. Can she rescue Isla and stop the killer before another silent girl is lost?

A gripping, heart-pounding and totally unputdownable Scottish crime thriller that will have you turning pages long into the night. Perfect for fans of JD Kirk, J M Dalgleish and Angela Marsons.
