Maxime Chattam who probably wants to clone or author like Michael Connelly son or Harlan Coben does not really manage to reach their level. While the story is fairly well written, clear and precise and the plot is relatively involved. It still reads this book with pleasure from beginning to end, although the quality is not at the level of the most famous authors of crime novels or American police. The story has no factual maturity, as written by a teenager for teenagers. ca sorely lacking in originality. It would make a good episode of "Experts", nothing more. A book that is packed more excessive clichés about the American scientific police and the FBI ... We feel here the author "French" in awe of his mentors and his American fantasies point barrre.
