It’s just a normal morning for Anna McDonald, until she opens the front door to her best friend, Estelle. Anna turns to see her own husband at the top of the stairs. They’re leaving together and they’re taking Anna’s two daughters with them. Left alone, Anna can’t take it in. With her world shattered, she distracts herself with a true-crime podcast. There’s a sunken yacht in the Mediterranean, multiple murders and a hint of corruption. Then Anna realises she knew one of the victims in another life. She is convinced she knows what happened. She throws herself into the case, but little does she know, her past and present lives are about to collide, sending everything into freefall.
