The exciting new standalone thriller from the No. 1 bestselling mistress of suspense and author of Widows, now a major motion picture

'Please don't let anything bad have happened to her, please don't let anything have happened to my baby…'

Marcus and Lena Fulford are the envy of their friends. Wealthy, attractive and successful, the couple, with their strikingly beautiful teenage daughter Amy, seem settled and content. But appearances mask a strained relationship almost at breaking point. Marcus's latest business venture has failed, draining Lena, the major breadwinner, dry. Putting Amy into weekly boarding school and striving to get her own career back on its feet, Lena remains alone in the luxurious family house as her marriage heads towards as amicable a divorce as she and Marcus can muster, and joint custody of their only child.

So when Amy arranges a sleepover with a school friend one weekend, neither parent sees the need to be in touch with her. Saturday, Sunday, Monday morning pass before Lena - seething from her first, unexpectedly confrontational, meeting with Marcus's divorce lawyer - phones Amy. Straight to Amy's voicemail. She must be in lessons. Lena sends a text. She waits. No reply, no contact whatsoever. It is only when Amy is reported missing from school and her friend's mother reveals that, instead of staying with them, Amy was visiting her father - a fact vehemently denied by Marcus - that Lena contacts the police. Her daughter has not been seen since Saturday afternoon.

As the police intensify their enquiries, their reassurances that Amy will be found safe and well begin to sound increasingly hollow. DI Victor Reid, in charge of the case, fears the worst - abduction or murder. A family under constant police and press scrutiny, a father who has seemingly lied about his alibi for the weekend, a mother whose perfect world is crumbling beneath her feet, a detective under pressure from his impatient superiors to deliver a result, the length of time that Amy has been missing gathering speed… all conspire to make Lynda La Plante's latest thriller her most tense and terrifying yet.

Where is Amy? Is she alive or dead? Lies and betrayal mount as the hunt for a missing girl becomes a search for a body…
