**One of the New York Times Book Review's Top Ten Best Crime Novels of 2020
"[McMahon] tells his story with flair."--New York Times Book Review
The author of The Good Detective delivers a gripping and atmospheric new novel in which a cop takes on a harrowing case and confronts old personal demons.
What if the one good thing you did in your life doomed you to die?**
A hard-nosed real estate baron is dead, and detectives P.T. Marsh and Remy Morgan learn there's a long list of suspects. Mason Falls, Georgia, may be a small town, but Ennis Fultz had filled it with professional rivals, angry neighbors, and a wronged ex-wife. And when Marsh realizes that this potential murder might be the least of his troubles, he begins to see what happens when ordinary people become capable of evil.
As Marsh and Morgan dig into the case, it becomes clear that Fultz's death was not an isolated case of revenge. It may be part of a dark web of crimes connected to an accident that up-ended Marsh's life a couple years earlier--and that now threatens the life of a young child. Marsh veers dangerously off track as his search for clues becomes personal..and brings him to a place where a man's good deeds turn out to be more dangerous than his worst crimes.
