Mustique is in a state of breathless calm as tropical storm Cristobal edges towards it across the Atlantic. Most villa owners have escaped the island but a few young socialites remain, unwilling to let summer’s partying end. American heiress Amanda Fortini is one such thrill-seeker – until she heads out for a morning swim and doesn’t return. Detective Sergeant Samuel Wilton is just 28 years old and the island’s only fully trained police officer. He quickly realises he needs to contact Lord and Lady Blake, who bought the island decades ago and have invested time, money and love creating a paradise. Jasper is in St Lucia designing a new village of luxury villas but Lady Veronica (Vee to her friends) catches a plane immediately. Her beloved god-daughter, Lily, is on the island and this disappearance has alarming echoes of what happened to Lily’s mother many years ago.
