The tent door flutters in the warm breeze, opening toward the silent woods beyond. A silk eye mask lies on top of the empty sleeping bag, blood-red spots ruining the cream fabric....

When a woman disappears from Forest Pines campsite, Detective Morgan Brookes scrambles a search party. Sara Fletcher has never missed a lunch date with her best friend, and when Morgan finds a large rip in Sara’s tent, she knows that something terrible must have happened. About to lose hope after hours combing through the acres of dense forest, the excited bark of a tracker dog leads Morgan to female remains, partially covered by leaves and dirt - but the bones don’t belong to Sara.

Morgan trawls through missing persons files until she finds three cold cases with chilling similarities - three other victims dating back 20 years who were taken from campsites while they slept, by a killer the police called The Travelling Man. The post-mortems indicate he kept them alive for 72 hours, meaning every second is crucial to find Sara alive.

Morgan’s team is terrified that this twisted murderer has returned. But Morgan also can’t ignore the fact that a merciless killer from her own past has recently escaped from prison.... Could they be chasing the wrong man? If she’s correct, how deep will she have to dig to save Sara and other innocent women like her before time runs out for them all?
