Amazon's rating system is not completely developed because Huchet wanted to complain (probably rightly) to a malfunction of the electronic book, the Kindle format. But in any case it did mean that we wanted this book is a "stew", that the single star could suggest a user unfamiliar with the rating system. When scrolling gallery or a list of books, a reader unfamiliar with the Amazon system may misunderstand and think that "Maigret" is a work of poor quality. This is certainly not the case.
This sanction was not about scoring, you'll all understand, the literary quality of the novel entitled "Maigret".
