Detective fiction premise, atypical execution: people are getting killed, police are trying to catch who did it — just like every other story. This one follows Sungmin Park, an ordinary human with strange markings on his body, and Clyde Martin, a demon with a bad temper, working together as consultants for the Elon State Police on the murder of Samantha Liebrecht. Sungmin, an outsider to Elon, finds supernatural complications, twisted politics, and the most dangerous thing of all: humans.
