The Purity of Vengeance

Detective Carl Mørck and his Department Q team investigate cold cases from their basement office in Copenhagen. When a message appears on their wall about an old disappearance, they begin looking into a series of missing persons cases from 1987. The investigation leads them through Denmark's dark past of forced sterilization at women's institutions and government-sanctioned medical experiments. At the same time, Mørck must navigate complex dynamics with his enigmatic assistant Assad and their new team member Rose. The dual timeline narrative moves between present-day Copenhagen and events of the 1950s through 1980s. The story connects seemingly unrelated characters whose paths intersect through buried secrets and long-hidden crimes. This fourth installment in the Department Q series examines themes of institutional power, accountability, and the human cost of misguided social engineering policies. The book raises questions about justice and whether vengeance can ever truly bring resolution to past wrongs.
