Simenon was one of the most prolific writers of the twentieth century, capable of writing 60 to 80 pages per day. His oeuvre includes nearly 200 novels, over 150 novellas, several autobiographical works, numerous articles, and scores of pulp novels written under more than two dozen pseudonyms. Altogether, about 550 million copies of his works have been printed.
The richest wine merchant in Paris is found dead -- shot in front of an elegant house where discreet clients are in the habit of renting rooms for discreet purposes. Everything seems to point to a crime sparked by jealousy. But Maigret is surprised to find a curious absence of shock or grief in the victim's family and colleagues, and further investigation into the life and habits of the murdered man reveals some singularly unlovable traits.
