In the tomb-like silence of an abandoned rock quarry, someone is trying to hide their dirty little secret. A secret that reveals the depths of human depravity. A secret that is about to be discovered.
When Special Agent Maggie O'Dell receives a concerned phone call from Dr Gwen Patterson about a missing patient, she agrees "unofficially" to look into the woman's disappearance.
At first, she dismisses Gwen's fears, but then the body of a woman is discovered in a fifty-five-gallon drum buried in an abandoned rock quarry. Then more bodies, in more drums, are unearthed.
Is there a link between the missing patient and the murdered woman? As Maggie is drawn into a case that confounds even a seasoned profiler like herself, she realises that she will need to dig deeper into her own resources than ever before. For this is undoubtedly the work of a serial killer, a killer obsessed with collecting trophies from his victims.
