The head of the French Ministry of Justice is very worried about his sister. She lives in Belgium where she is married to Etienne Naud, a rich Belgian horse breeder. Rumors are circulating throughout their village that accuse Naud of murdering a young man. The head of the French Ministry asks Maigret to go to Belgium to stop the defamatory rumours. An off-the-record favour, to be accomplished with the utmost discretion, of course. On the train, Maigret is surprised to see Mr. Cavre, an ex-law enforcement officer whose nickname was "Inspector Cadaver". Mr. Cavre has since opted for a career as a private investigator. Upon arrival, Maigret continues to be surprised. No matter where he goes in the village to conduct his investigation, Cavre has been there before him. Obviously, the detective is there for the same reasons.... Who hired Cavre? The murderer? But, did a murder really take place? Was it not, perhaps, an accident? Maigret is convinced that it is Inspector Cadaver who holds the key to the whole affair... Directed by Pierre Joassin, 1998, color. In French with English subtitles.
