Maigret: Night at the Crossroads

Jeweller Isaac Goldberg leaves Antwerp with a cache of stolen diamonds but his body is found in the French village of Arpajon in a car belonging to aloof Dane Carl Anderson. Other villagers dislike him, telling Maigret he keeps his sister Else locked in her room and, whilst protesting his innocence, Carl attempts suicide when Maigret discovers that there are no records of his existence. Nonetheless Maigret releases him in the hopes that he will lead him to the missing diamonds and the actual murderer. The death of another suspect causes Maigret to believe the killer is one of the other villagers working in collusion with a member of the police force.
