Long before Chief Inspector Viktor Marek worked as a crime scene inspector for ARD, he cleared up a murder case on Austrian television year after year. The idea originally came from Friedrich Redl, and the main actor Fritz Eckhardt himself wrote the screenplay for the last four episodes. Eckhardt's motto "10 scenes of 10 minutes each is a 100-minute film" was used in it and also in the later Tatort episodes. Kurt Jaggberg was there from the start as District Inspector Otto Wirz. Albert Roland acted in supporting roles as Inspector Berntner and the secretaries Franzi (Elisabeth Rusa) and Susi (Liselotte Plauensteiner).
