Yesterday while browsing the Bare Knuckles Press website, I learned a new term: Roman Durs. I guess it is French for hard novel.
They are stories that are very existential and dark. The main character is also very unlikeable and has no moral compass. These stories were often equated with George Simenon. They are also compared to the writings of Albert Camus. I also think they are along the lines of the stuff that Celine wrote.
I will put George Simenon on my list of authors to read.
