Maj Sjöwall and Per Wahlöö are writers of a series of immensely popular "police procedurals," or novels in which the police, while carefully following their own real-life rules and procedures, solve a crime or close a case. Many of these novels have been translated into English, and they have done respectable business in the U.S. In this film, the chase is on when a fatal fire leads the police to suspect a drug group. ~ Clarke Fountain, Rovi
