A young man is found beaten to death, the most sacred areas of a Catholic church are desecrated, a sabotaged railroad track leads to a deadly derailment, and a Jewish holocaust survivor is hung in effigy. All happen in too short a time span to say they are not related, and Deidre Johnson is brought out of retirement to solve the crimes. Suspect groups are identified, and a process of elimination begins, ending in a life-altering experience for her. Preying in Two Harbors is the fourth book of the Two Harbors mystery series written by Dennis Herschbach.
