The Marquise De Brinvilliers

Alexandre Dumas ( born Dumas Davy de la Pailleterie, 24 July 1802 – 5 December 1870) was a French writer, best known for his historical novels of high adventure. Translated into nearly 100 languages, these have made him one of the most widely read French authors in the world. Many of his novels, including The Count of Monte Cristo, The Three Musketeers, Twenty Years After, and The Vicomte de Bragelonne were originally published as serials. His novels have been adapted since the early twentieth century for nearly 200 films. Dumas' last novel, The Knight of Sainte-Hermine, unfinished at his death, was completed by a scholar and published in 2005, becoming a bestseller. It was published in English in 2008 as The Last Cavalier.
