The Retreat

An eco-wellness retreat has opened on an island off the coast of Devon, promising rest and relaxation - but the island has a dark past. Once the playground of a serial killer, it's rumoured to be cursed. DS Elin Warner is called to the retreat when a young woman's body is found on the rocks, in what seems to be a tragic fall. But the victim wasn't a guest - she wasn't meant to be on the island at all. The new novel from the bestselling author of "Sanatorium".
