Young Charlotte de Fontenac married Count de Saint-Fourge, a nobleman from the retinue of the king’s brother—for convenience. She needs a loud title and the status of a married woman in order to shine at court. The girl’s seductive beauty attracts the count far less than the secret of the treasures brought to him by her father from India: rubies, emeralds, star sapphires, and a rare diamond of purest water in a delicate golden-yellow color. These jewels could improve the young husband’s financial situation and bring honor to the royal treasure-house. So the trusting Charlotte is drawn into a chain of crimes at the Versailles court during the reign of Louis XIV.
