If you enjoy this Maigret series, I would recommend looking for this episode, if you missed It. It is unusual for a couple of reasons.
First, because it is about Maigret's returning home for the first time in decades, due to a mysterious letter he received. Maigret's ambivalence about returning back to the provincial home of his birth, the memories, and the people still there, make it an interesting show to watch.
Bruno Cremer does a wonderful job of revealing shifting emotions, with a raised eyebrow, or an extra puff of his pipe. Add to this the death of a Countess Maigret knew as a boy with Maigret trying to figure out if she was murdered or died of natural causes.
The second, even more unusual feature, is the presence of Madame Maigret, Anne Bellec, throughout much of the episode. Madame Maigret has accompanied her husband to his home town, to see where he grew up.
Madame Maigret's own reactions to the people she meets--cool toward the Countess, while delighted meeting a woman who had a crush on Maigret--are as fascinating to watch as Maigret's. opaque behavior. Add to this, scenes showing Madame Maigret annoyed at her husband and his petulant response.
Very little of Maigret's thoughts and reactions are ever "fleshed-out" or explained. They are simply there to be observed. It made, I found, for a particularly intelligent and intimate episode of Maigret.
