One of the central characters in this gripping detective series is the picturesque city of Potsdam. Here the childhood friends Luna Kunath and Sophie Pohlmann work together to solve a string of crimes. While Luna is strong-willed and thinks on her feet, she can be a little naïve. Although more mature, Sophie’s reflectiveness can be a weakness in situations that demand decisive action. Together the two women form part of an impressive crime-busting team.
