Chief Inspector Pit "Struller" Struhlmann is furious. Right in the jurisdiction of the Düsseldorf homicide squad, body parts are suddenly being found scattered all over the city. This is hardly professional work! And just at this moment, he is assigned Christian Jensen, an intern from the Duisburg University of Applied Sciences. Interns know nothing, just get in the way, and think they know better. Their investigations lead the mismatched pair to the chic beauty salons on Königsallee, to the beautiful viewpoint in Grafenberg, through grimy backyards in Flingern, to Lady Pia, and even into the deepest, most hidden corners of the police headquarters. Gradually, they bring order to the chaos of body parts, and Struller is almost satisfied.
