When an old colleague comes to him for help solving the mysterious death of his town's most prominent resident, retired NYPD detective Dave Gurney must use all of his analytical skills to hunt a murderer who just might be killing from beyond the grave.

The idyllic community of Larchfield is rocked to its core when Angus Russell, its wealthiest and most powerful citizen, is found dead in his mansion on Harrow Hill. A preliminary analysis of DNA gathered at the crime scene points to the guilt of local bad boy Billy Tate, whose hatred for the victim was well known. Except that Tate fell from the roof of a local church and was declared dead by the medical examiner the day before Russell was killed. When police rush to the mortuary, they discover Tate's coffin has been broken open from the inside and the body is gone. 

A series of murders soon follows as Larchfield loses its collective mind. Gun sales explode. Conspiracy theories and religious fundamentalism spread. The once-peaceful town becomes a magnet for sensation seekers, self-proclaimed zombie hunters, TV producers eager for ratings, and apocalyptic preachers rallying the faithful for the end of days. His quiet retirement shattered, ex-NYPD detective Dave Gurney finds himself not only facing down a murderer, but struggling to restore order to the town rapidly spiraling out of control.
