Alexandre Dumas 
The Marquise de Ganges 

The assassination of Diane de Joannis de Chateaublanc (the Marquise de Ganges) is a fitting tale to conclude Dumas’ celebrated crimes series. This event was as gruesome as it was brazening and, before the final dagger strokes, both the assassins and the assassinated had become embroiled in high-profile intrigues. As a result, it sent reverberations through common and court societies across Europe for decades.
