Chief Inspectors Saalfeld and Keppler are called to an apparent suicide in a side canal of the Elster. Since the police divers were unable to find Carla Schütz's body, Eva Saalfeld ordered an extended search operation. She sees signs of a violent crime—unlike Keppler. When he is informed that a man has been found dead and tied up in his bathtub, he is left at the "crime scene" no longer. The commissioners are now investigating separately.
