I am going to spoil Maigret Stonewalled since it has left me so incredulous:
Maigret is investigating a suicide by a man who has with him an old, bloody suit that wasn't his and that he took with him everywhere he went. The man was miserable, an alcoholic with a blue collar job, a wife and a child. However, he seemed to have a better education than would have been expected.
Maigret unwinds an old story involving a group of students in their early 20s meeting to drink, party and talk a mixture of Marx, Confucius and Jesus Christ that they called philosophy. And of course, they considered themselves super-enlightened and were going to make the world a better place while despising petite bourgeoisie and other usual suspects.
This took place 10 years before the narrative. It was a mixed socio-economic group with the haves and have nots taking part in the festivities on the regular basis. But the odd man out was a Jewish student who was as wealthy as some of the others but wouldn't pay his "fair share" which was meant more than the poorer students, and who seemed to despise the others quite a bit and even refused to get drunk with them. He only came to observe and to sneer, it seemed.
So one night the kids talk about how easy it would be to kill someone (what was that great book about murder in a New England college?). And on Christmas Eve they get drunk/doped up enough to seriously consider it. Who shows up, all annoyingly sober and clean-cut but the Jew. He refuses to go buy them more alcohol because in his opinion they are drunk enough. And they are because the Jew gets killed and dumped into the river. The body is never discovered The group inevitably breaks up and most move on. But the one who dealt the fatal blow ends up hanging himself. And one other ends up blackmailing the well off remainder of the group.
Maigret unwinds this whole story and in the end decides to drop the case. Why, one might ask? Because the surviving men in the group have children, for one. And because the good God in Heaven takes it upon Himself to do police work--the survivors were punished enough by their remorse. Never mind that 2 out of 3 of them tried to kill Maigret at various points of the investigation. Never mind that they aided, abetted and concealed a murder. But they have children now and have suffered enough. And nothing is more funny than life anyway. Fin.
Really???? I would have been shocked that Maigret took it upon himself to be the judge and the jury in this case had I not known a little something about Simenon. Maigret goes after the murderer with steady ferocity in all other novels I've read so far. But not in this one.
