El retiro

A wellness retreat has just opened on the English island of Reaper's Rock, promising rest and relaxation to all its guests, but the island is rumored to be cursed and once the playground of a serial killer. Detective Elin Warner comes to the retreat when the body of a young woman is washed up on the rocks below the yoga pavilion in what appears to be a tragic fall. The strange thing is that the victim was not staying at the retreat. When a guest drowns in a diving incident the next day, Elin begins to suspect that there was nothing accidental about these deaths. But why would anyone target guests? And who else is in danger?
