A mother in mourning

Two years ago, Sarah's husband was jailed for her murder; her body was never found. Now, her grieving mother, Claire, spends her sleepless nights running a helpline for vulnerable women.

Claire takes many calls, but one caller isn't like the rest. She isn't calling for help ? she's calling because she claims to know what happened to Sarah.

A killer on the loose

But when Claire hears the terrifying news that her daughter's killer has escaped from prison, she realises her nightmare is far from over ? and her family are in danger yet again.
