It is characterized by its dark themes, complex characters, and a focus on social issues. The stories often feature morally ambiguous protagonists and explore the darker aspects of society, such as corruption, inequality, and violence. This genre gained international popularity through authors like Stieg Larsson and his Millennium Trilogy, as well as Jo Nesbø and Henning Mankell. The atmospheric settings, often depicting bleak landscapes and harsh climates, contribute to the overall mood, making it distinct from other crime fiction styles.
