Tatort S2012E21 - Borowski - 19 - Borowski und der stille Gast

A desperate call alerted the Kiel police emergency number: "He's in my apartment. He just comes through the wall." But for Carmen Kessler, any help comes too late. The young woman is found brutally murdered in her apartment. Inspector Borowski and his colleague Sarah Brandt are puzzled: Although the apartment door is locked and the perpetrator left no traces at the crime scene, the murderer seems to have been in and out of the victim's house. He stayed with her secretly, gave her anonymous gifts and studied every habit of his victim.
