During a final visit to the cell of condemned prisoner Jean Lenoir, Maigret picks up a negligently dropped remark about an unsolved-in fact, unreported-murder committed in Paris six years before. It seems Lenoir and his partner witnessed the dumping of a body in the Saint-Martin Canal and used the information to blackmail the murderer.
