After joining the Commissioner Adamsberg along the way, I go back to basics by reading its first investigation. The primary interest of "Man with blue circles" is how to set the scene and characters (Adamsberg Danglard course, but also for example). The particular world of Fred Vargas, made Mists of Adamsberg, atypical characters and cracks of a poetry that creeps into the staging of crimes, is already there. For the moment, I liked all the "rompols" of the author, and this album is not lacking. It is true that the outcome is at the limit of credibility. I have nevertheless adhered because it is really led on one side by the erratic path of the Commissioner and the other by almost insignificant details scattered throughout the pages.
