Saw this on Talking Pictures channel (UK - old films and TV) who are running all 4 of this original Maigret series (BBC, early 60s). This episode featured a man, inoffensive and polite, murdered when he should have been working, and his rather stuffy wife says he was wearing the wrong clothes?
Maigret gets to work, and with the team discovers that he lost his job 3 years ago, and has a room in the city (but his wife is in the suburbs, he leaves there and returns every day). What can be going on?
They find the woman he sees most days, and start to seek out anyone who knows what he does these days. He has a daughter too, does she know more than she admits? By the end of series 2, the supporting actors were generally better than some of the shows in series 1, like this one, which had the likes of Stratford Johns (soon of Z Cars fame).
It also shows a trait of the Maigret books, his occasional bond with the professional criminals he has to meet, and a sort of grudging mutual respect. One such offers a clue as to how the victim now earns his money. Overall a good episode.
