This is actually the first Maigret novel and you can see that some of the familiar tropes have yet to develop. The story concerns an apparent murder in a small town outside Paris, where Maigret has to stay in a hotel and generally observe what goes on.
As in all of the Maigret novels I have read, the reader never sees things through the eyes of any character but the man himself. Motivations are divined by Maigret and then confirmed in conversation. The weather always gets a prominent role and his gustatory and bibulous activities are always interesting.
