Tempted by a number of recommendations, including an article in "Figaro", I downloaded a sample of Fermat's conjecture; recent proof of this theorem makes it a subject of curiosity; and associate it with the idea of encrypting messages seems interesting. But, knowing that publishes a book as fast as rejects, I was through with the extract. Alas, he is the author neglecting a historian? It is certainly capable of the worst: In this excerpt from the book, it arms a jumper with a musket! Either he found inspiration in a western and confused and Winchester musket, or he does not know what a musket, weapon foot in Europe if any, from four to seven kilograms, which may possibly have been brought with her Fourquin by a pack horse, but never hung on the tree as a light weapon hunter in the seventeenth or eighteenth century. Jean d'Aillon obviously confuses the rifled muskets and rifles first, imprecise and complicated to implement on horseback, which may have fitted very wealthy hunters, but certainly not included in the armory of a fresh young squire distinguished by Mazarin Elsewhere he refers Utrecht, major treaty in effect for the future of Europe but the author fails Britain among the negotiators, whose delegation is led by the brilliant young Viscount Bolingbroke Minister who will play a role eminent. That's two big mistakes in an extract of a few pages! These examples make me fear that further novel contains many other blunders or annoying nonsense of this ilk. In short, the history cooled amateurism of the author, I expect other echoes before letting me go to the checkout.
