Swedish detective writer Per Wahlöö and his wife Mai Sjöwall are known for their series of books about Martin Beck, the commissioner of the Stockholm police. These works have greatly contributed to the development of Scandinavian noir, a genre of dark and suspenseful stories. Per Wahlöö was a staunch communist and a proponent of Marxism-Leninism. In his books, he was not afraid to expose the essence of capitalism and its role in the rise of crime. The main character, Martin, works in a team with ordinary people and constantly faces the arbitrariness of those in power, the elite, and the people who have suffered from them. Mr. Wahlöö knew how to use the entertainment genre and the writer’s skill to make the reader think about important things.
