Buried

A retired copper's son is kidnapped. Many of the villains he put away had sworn revenge. So why doesn't he mention the one who is still the main suspect in a four-year-old murder? Is this a simple oversight, understandable considering the trauma of his son's disappearance? Or is it something more telling? Aware that he hasn't the luxury of time, Detective Inspector Tom Thorne searches desperately for connections and leads, but learns that secrets are as easily buried as bodies, and that assumptions are the enemies of truth.
