Very well researched and written book on a period of French history that not many may know about. The Affair of the Poisons was a time during the reign of King Louis XIV when it was believed that many royals were being poisoned by loved ones, more than their nemeses. It was similar to the Salem witch trials in that people were fascinated with horoscopes, séances, love potions, and aphrodisiac powders and oils that they used on loved ones, or those whose affection they desired. What transpired were actual poisonings and black magic ceremonies. The main focus was gradually, due to evidence and interrogations, pointed to the King's number one Mistress, Madame de Montespan. She bore him 6 children; all legitimized. A rarity in those days, this was a true love affair that lasted for decades. However, when all evidence pointed to her, the King literally could not face having her imprisoned, much less hanged, for her actions against him and the other mistress in his court that he had fond affection for; a woman Mme. de Montespan considered a true rival for his affection. This is not a "light" history lesson. There is a lot of heavy, dark history retold here. It is fascinating. And I cannot imagine having to conduct this investigation, and listening to horrific stories of those who were killed at the hands of these practitioners of the dark arts. I highly recommend this book.
