Very good start but average end.

The first part is drôlissime! The role of the hero (in undercover) is a real treat! And luckily it's there to make us laugh and give lightness to the story because the rest is pretty disappointing. Besides, as soon as he abandons his idiot character, the novel loses its flavor and falls a little in trouble.
Too bad because this book could have gone very good A & P.
