Conrad Susa's three-act opera with libretto by Philip Littell, is based on the scandalous 18th century novel by Pierre Chodelos de Laclos, a tale of decadence and revenge told entirely in letters. The plot of The Dangerous Liaisons revolves around the vengeful widow Marquise de Merteuil, who has managed to keep her reputation despite her many amorous affairs, and her sometime lover the Vicomte de Valmont, a well-born rake who does her bidding.
