Winter has come to North Carolina and, with it, a drop in crime. Freed from a heavy work schedule, Tempe Brennan is content to dote on her daughter Katy, finally returned to civilian life from the army. But when mother and daughter meet at Tempe’s place one night, they find a box on the back porch. Inside: a very fresh human eyeball.

GPS coordinates etched into the eyeball lead to a Benedictine monastery where an equally macabre discovery awaits. Soon after, Tempe examines a mummified corpse in a state park, and her anxiety deepens.

There seems to be no pattern to the subsequent killings uncovered, except that each mimics in some way a homicide that a younger Tempe had been called in to analyze. Who or what is targeting her, and why?
