Set in the 1970s in a run-down, rainy industrial town, Jo Nesbo's Macbeth centers around a police force struggling to shed an incessant drug problem. Duncan, chief of police, is idealistic and visionary, a dream to the townspeople but a nightmare for criminals. The drug trade is ruled by two drug lords, one of whom—a master of manipulation named Hecate—has connections with the highest in power, and plans to use them to get his way.
