Thunder rattles the windows of the deserted hotel. Morgan spots the young girl on the floor, her dark hair fanned out and covered in shattered glass. Lightning strikes, illuminating the blood on every surface.

Following an emergency call in the middle of a fierce storm, Detective Morgan Brookes arrives at Keswick Manor, a crumbling, empty hotel in the Lake District, where she finds the dead body of a young woman. She recognises her bright blue eyes instantly. Lauren Williams’ body is still warm to the touch, a knife protruding out of her chest, just like the one that killed her sister, Lydia, one month ago. But the killer in that case is dead…

Morgan can’t imagine the horror Lauren went through as she combs the scene; a broken radio on the stairs suggest she was running from someone. Lauren knew her sister was murdered, did she know she was next? Grief-stricken, Morgan sets to work on Lydia’s case files and refuses to sleep until she’s uncovered any small clue she missed. But by the time she discovers they had another sister, the poor girl is reported missing, her pink car found abandoned in the local woods surrounded by overgrown brambles.

When Morgan spots a police identification number scribbled in the family’s old police files, she realises that one of her colleagues has been lying to her. The idea that someone at HQ is in league with a serial killer would send terrifying shockwaves through Rydal Falls, but Morgan can think of no other explanation. Can she save the final sister and catch this killer as a terrifying countdown begins? Or with evil closer than she thinks, watching Morgan’s every move, is she already in too much danger?

Fans of Angela Marsons, Lisa Regan and Rachel Abbott will devour this unforgettable rollercoaster crime thriller late into the night.
