Die Füchsin - Dunkle Fährte(2015)

Mid-fifties Anne Marie Fuchs lives modestly and withdrawn in Düsseldorf. When a murder happens, it becomes clear that the inconspicuous lady, who is always in short supply, seems to be an absolute investigator with a razor-sharp mind. No wonder, because Anne Marie Fuchs is a former East German spy, especially one who still has a bill from her active time open.
