None but the Dead (11) (Rhona MacLeod), Lin Anderson

Sanday, one of Britain's northernmost islands, is inaccessible when wind prevents the ferry crossing, or fog grounds the tiny plane. When human remains are discovered by an old school, forensic expert Dr. Rhona MacLeod and her assistant are called. Approaching midwinter, they find daylight in short supply and some of the island's inhabitants less than co-operative. When the suspicious death of an old man in Glasgow appears to have links with the island, DS Michael McNab is dispatched to investigate. Desperately uncomfortable in such surroundings, he finds no internet, no CCTV, and no police station. As a major storm approaches, bringing gale-force winds and high seas, the islanders turn on one another, as long buried secrets break the surface, along with the exposed bones.
