A group of old university friends leave the bright lights of London and travel to Unst, Shetland's most northerly island, to celebrate the marriage of one of their friends to a Shetlander. But late on the night of the wedding party, one of them, Eleanor, disappears - apparently into thin air. It's mid-summer, a time of light nights and unexpected mists. The following day, Eleanor's friend Polly receives an email. It reads like a suicide note, saying she'll never be found alive. And then Eleanor's body is discovered, lying in a small loch close to the cliff edge.Detectives Jimmy Perez and Willow Reeves are dispatched to Unst to investigate. Before she went missing, Eleanor claimed to have seen the ghost of a local child who drowned in the 1920s. Her interest in the legend of the ghost had seemed unhealthy - obsessive, even - to her friends: an indication of a troubled mind. But Jimmy and Willow are convinced that there is more to Eleanor's death than there first appears.Is there a secret that lies behind the myth? One so shocking that someone would kill - many years later - to protect?Ann Cleeves' striking new Shetland novel explores the tensions between tradition and modernity that lie deep at the heart of a community, and how events from the past can have devastating effects on the present.words : 100991
