This is not the best Maigret I have read but it has a strangely soothing tone. So little happens that it hardly constitites a crime novel at all. And what does happen is told rather than shown. So the violence quotient is low.
A man is murdered in his comfortable home. The last one to see him was his son-in-law over a game of chess. His wife and daughter-in-law were at the theater. He has to have let the murderer in.
Well, it is kind of irksome when the murderer turns up late in the book, never mentioned to then. And we only hear about his crime. So I would rate this as one of the least satisfying Maigrets. Although the writing is good and his thought process believable. So even a lesser Maigret is worth your time.
