The car of Irma Westermühl (Monika Baumgartner) is a 1975 Dodge Royal Monaco custom-made pickup. The same car will be used again in episode 11.07 ("Die Sünden der Väter") by automotive tuner Bernd Gröber (Horst Kummeth and is often visible as background vehicle in other episodes of the series.
First episode in which Matula has got to take care of Dr. Franck's dog Umba. Matula will become very attached to the dog during the series.
Differently than the common schema of the series, where Matula investigates and Dr. Franck takes care of the legal part of the story, here the plot is centered on Matula trying to find out Rainer, who is kept chained in a cellar.
