Queen of Diamonds 

A story of greed, duplicity, romance and intrigue, and a mystery said to have brought down the french monarchy.The world shook at the eruption of the French Revolution, a revolution, some say, precipitated by a single factor: the theft of the Diamond Necklace which, it seemed, had been commissioned for Marie Antoinette and helped to bring both her and King Louis XVI to the guillotine.But behind the scandal was a complex and daring conspiracy involving a Prince of the Royal House of France, the charming and deceitful countess Jeanne de Valois, and the infamous Comte de Cagliostro all pawns in a secret, devious plot for wealth and supremacy in Europe.
