Ten years ago, a boy named Samuel Murray went missing from the quiet village of Buckthorpe and was never seen again. Rosie Sharpe cried over her missing friend for weeks after. But her little sister, Heather, knows that Rosie’s tears hide the truth. Because the night Samuel was last seen, Heather watched her older sister climbing back through the window of their childhood bedroom. Her jacket torn, her eyes wild, and her body trembling with fear. Heather never told anyone what she saw, but secrets can’t stay buried forever....

Fran finds her standing by the swings. A little girl, Esther, no older than seven years old, by herself in the dead of night, her pretty but old-fashioned yellow dress covered in grass stains and her hair dishevelled. She says she's waiting for Father, and that strikes Fran as particularly odd. After Esther is reunited with her family, Fran can't stop thinking about this pious child whose imaginary friend is God. Fran's instincts tell her something is very wrong. Why does Esther keep running away from home, and how did she get that bruise on her leg?

Seven years ago, six-year-old Maisie Earnshaw was found facedown in a duck pond, her body mutilated. Isabel - at age 14, found covered in Maisie's blood - was convicted of murder. As Leah spends time with Isabel, she comes to know her as a young woman with a sweet, gentle nature, someone she could never see as a murderer. Leah begins to suspect members of the Fielding family of framing Isabel as a young girl, and she's not the only one. True crime blogger James Gorden thinks Isabel is innocent, too.

During a midnight journey snaking through the Carpathian Mountains, these are the words whispered to Cath Fenwick. It is the warning she will later wish she'd taken more seriously. When Cath receives her invitation to The Event - a monetised retreat for social media influencers - she can't believe her luck. Irene Jobert is the most famous influencer in the world and now Cath will be one of the five participants chosen to stay with Irene in a renovated Transylvanian monastery.

A production company wants to make a movie about Isabel Fielding’s life, but Leah knows this is a huge mistake. When the actress cast to play Leah is found murdered, she’s proven right in the grisliest of ways. It seems like a straightforward case: the deadliest ever female serial killer escaped prison a few hours before the murder. But Leah’s son Tom is first on the scene and Seb, Leah’s boyfriend, isn’t convinced by Tom’s innocent act. Even Leah must admit she doesn’t really know her son after he disappeared for months without contact.
