When the body of a woman is found in a stable beside a lock on the Marne canal, Maigret is called to investigate. It's a problematical case made the more puzzling by the seeming indifference of the dead woman's husband Sir Lampson (wonderful Michel Lonsdale). Bruno Cremer uses his usual analytical skill to solve the case.
The world of locks keepers and bargemen is brought alive in this episode, taken from the novel 'Le charretier de la "Providence"'. There is excellent use of the buildings and boats on the canal, made vivid by some fine cinematography. Michel Lonsdale reminds me once more why he is one of my favourite actors.
