Cases for the Commissioner contains two thrilling criminal cases from the television series The Commissioner, specifically adapted for German learners at B1 level. The first case, "Knife in the Back," tells the story of a man who suddenly collapses dead in a taxi. The second case, "Murder of Mrs. Klett," depicts a macabre crime against a single woman. With the help of his assistant and press photographer, the commissioner tackles the cases but faces significant challenges. The focus here is less on breathtaking action and more on the commissioner's understanding of the psyche of the perpetrators and the background of the crime.
