Maigret and the Wine Merchant

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.
