In 1675, a female vampire possessing the secret of immortality was burned alive. Forty-five years later, during a dinner at the table of the French Regent, her then-lover, Marquis de la Roche-Maubert, discovers that another guest, Chevalier d'Esparron, is in love with the same immortal woman. However, her attraction to him is not to satisfy her hunger for blood, but to implement one of the greatest secrets of alchemy: the transmutation of lead into gold!

Pierre-Alexis Ponson du Terrail (1829-1871) was a French popular writer and a master of the serialized novel, having penned over 200 such works in 20 years. He is justly famous for his character of Rocambole and his ground-breaking horror novel, The Vampire and the Devil's Son (1852). The Immortal Woman (1852) is a forgotten masterpiece of early vampire fiction, and another of Ponson's classic flirtations with the supernatural.
