In the early 1980s, a tight-knit Indiana community is struck by a series of violent murders.
Father Solomon Lancaster—the town's dry-witted sheriff and priest at the community Catholic church—finds himself on the forefront of the investigation. Soon, he's fighting to match wits with the serial killer terrorizing his town while trying to justify his law enforcement credentials to the FBI as their analysts and profilers take Crooked Creek, Indiana, by storm.
But Father Solomon is hiding secrets of his own. Ones that threaten to rise to the surface as the murders continue and the investigation draws nearer to the truth. As the killer begins to escalate, Father Solomon finds that even the innocent have dark sides, and trust might be the deadliest weapon of all.
