When a young archaeologist discovers a set of human remains, the locals are intrigued. Is it an ancient find or a more contemporary mystery? Then an elderly woman is fatally shot and Ann Cleeves's popular series detective Jimmy Perez is called in. As claustrophobic mists swirl around the island, Inspector Perez finds himself totally in the dark.

This series is the basis for the hit BBC show Shetland, starring Douglas Henshall, which attracted over 12 million viewers in its first two nights on the air.
