The Retreat

by Sarah Pearse (£14.99, HB, Bantam Press) DS Elin Warner is back – this time at a wellness retreat on a stunning island. In this clever thriller, the bestselling author of The Sanatorium puts us at the very heart of a murder when a woman’s body is found at the bottom of the cliff beneath the yoga pavilion. Not only that, but a storm is forecast, the islanders can’t leave and they are told to ignore the rumours about the island’s history. An addictive revenge story set on a remote island, it’s another hit for this must-read author.
