Comisario Dupin: Bretonische Spezialitäten

SINOPSIS

In the market hall of Saint-Malo, Commissioner Dupin witnesses how top restaurateur Blanche Trouin is stabbed by her sister Lucille. Lucille flees headlong, but is caught and arrested by Dupin. Since then she has remained silent. Dupin, who is always interested in understanding the background to an act, is faced with a mystery. He realizes it's not a cold-blooded planned murder, but why doesn't Lucille try to defend himself? Although the crime scene is apparently perfectly clear, Dupin begins the investigation. He meets Blanche's husband Kilian, who seems less affected by Blanche's death than by Lucille's deed, and Charles Braz, Lucille's partner, who at first tries in panic to flee from Dupin. Nobody plays with open cards, everyone is hiding something. Dupin senses that there is more to the violence than a deadly argument between sisters. When there are two more murder victims, Dupin knows that his instincts have not deceived him.
