Dangerous Liaisons (Les Liaisons Dangereuses)

The Dangerous Liaisons is a French epistolary novel by Pierre Choderlos de Laclos, first published in four volumes by Durand Neveu from March 23, 1782.
It is the story of the Marquise de Merteuil and the Vicomte de Valmont, two rivals (and ex-lovers) who use sex as a weapon to humiliate and degrade others, all the while enjoying their cruel games. It has been claimed to depict the decadence of the French aristocracy shortly before the French Revolution, thereby exposing the perversions of the so-called Ancien Régime. However, it has also been described as a vague, amoral story.
