Paris, the City of Light, has always harbored darkness. In this episode, we investigate the true story of the Parisian Vampire—a mysterious figure who terrorized cemeteries in the 1840s, forcing open coffins and mutilating corpses beneath the shadow of Notre-Dame. We'll explore the case of François Bertrand, the grave robber who inspired the legend, and the enigmatic tomb of Elisabeth Demidoff, whose mausoleum became the center of a macabre challenge. From scholarly debates to the Vampire Museum of Paris, we ask: what really stalks the streets after dark?
