Always the same pleasure to meet Nicolas Le Floc'h! This time, his adventure is related closely to the progress of his century: politics gets involved and it takes tenacity and righteousness of our hero, assisted by his loyal Bourdeau, to complete this complex investigation, including all strive to divert it by any means-including trying to tuer- and he'll know the betrayal and disappointment from people he wore his confidence (I can not tell you that ...) Nicolas Le Floc'h continues to take us with him through Paris and Versailles, at a frenzied pace, with breathtaking descriptions of life at the time. One regret: that is to date the last book of the series and will now have to wait for JF Parot write later !!!
