Though to be honest, real people sometimes act in unrealistic ways.
Remember the story you posted about the guy who burned down the courthouse so he wouldn't go to court for a traffic violation. All he had to do was go to court, receive the penalty for a minor offense, and be done with it. Now he's facing a bigger charge on top of that.
Although I liked the story and the various plot developments that came out of it, I do agree with the criticism that it ended without providing much of a shakeup to the status quo, and that the ending was a bit anticlimactic (though having people figure out Jean was the culprit beforehand contributed to that a bit).
