S1·E30 Murder in a Vegetable Garden

Maigret travels to Dole after a gun found with a murdered "vagrant" matched one used to kill another "vagrant" under a Paris bridge. There he encounters a pair of feuding sisters, one of whom owns the shed the victim was found in. The feud has been going on for 30 years, the source of which is both clear and muddied at the same time, just like the weather.
