A group of old university friends leaves the bright lights of London and travels to Unst, Shetland's most northerly island, to celebrate the marriage of a friend. But late on the night of the wedding party, one of them, Eleanor, disappears - apparently into thin air. Soon her body is discovered, lying in a small loch close to the cliff edge, and Detectives Jimmy Perez and Willow Reeves are dispatched to investigate. Before she went missing, Eleanor claimed to have seen the ghost of a local child who drowned in the 1920s. Jimmy and Willow are convinced that there's more to Eleanor's death than they first thought. Is there a secret that lies behind the myth - one so shocking that someone would kill many years later to protect it?
