For the first time since the beloved Shetland series, Detective Jimmy Perez is back. He's traded the stark beauty of Shetland for the wild isolation of Orkney, but the darkness of human nature follows him everywhere. When a ferocious storm rages across the islands, it leaves behind more than just damage: it uncovers the body of Archie Stout, a popular, larger-than-life member of the community. The murder weapon? A Neolithic stone, bearing cryptic, ancient inscriptions. Now living in Orkney with his partner, Willow, and their young son, Perez is drawn into a case that is chillingly personal-Archie was a friend from his own childhood. And the island is full of familiar faces, all of whom are potential suspects in the killing. Perez must immerse himself in the lives of the islanders, separating truth from local legend before a desperate killer can strike again... and threaten the new life he's desperately trying to build.
