Buried Angels by Patricia Gibney

Bubbles of cold sweat trickled down Faye’s spine. The hole wasn’t empty. Before she could turn and run, she caught the two sightless eyes staring up at her. Only then did she scream.

When Faye Baker discovers a fragile child’s skull behind the walls of her new home, Detective Lottie Parker is called to investigate. The house has been owned for years by the family of Faye’s boyfriend Jeff, so when Jeff starts acting suspiciously, Lottie wonders what he might be hiding…
Lottie doesn’t have long to dig deeper before a child’s bones are found by eleven-year-old Gavin on nearby railway tracks. The bones don’t match the small skull behind the walls, but Lottie can’t ignore the coincidence. Someone out there must be missing their loved ones and it’s up to her to put right a terrible wrong.

Unable to shake a feeling of foreboding, Lottie goes to speak to Faye, and discovers that she hasn’t turned up for work. When Faye’s body is found stuffed in the back of her car, Lottie needs to find out who wanted her to keep quiet.
As Lottie hunts for Faye’s killer, the case takes a darker turn when Gavin goes missing. Faye and Gavin are connected only by the grisly body parts they discovered. But who are these little victims and why has their killer come back? Can Lottie find the answers before another precious life is taken?
