As in "Copernicus syndrome", the story told by Loevenbruck is one such model. Based on the history of books a prime contractor of the thirteenth century, the author shows a far higher talent to fade "Da Vinci Code"; the puzzles are much worked, compared with monuments or historical facts is much more insightful. You literally enthralled by this story and more information is expected in the pages. By cons, in characters, that's the rub. They are really caricatures, Ari hero cop is a dark, melancholic analyst at RG. But when we tickle it connects the commando operations, France, Italy, ... kill all the bad guys to submachine gun, grenade ... Of course, all this without reinforcement. Shame in relation to the quality of the story.
