Inspector DuPont led the investigation in Paris in 1895 when an alien time-vampire stalked the streets, stealing time from people's lives (as well as animals and plants).

He was assisted by Baron De Guerre, who was really Varlos, former brother of the Darksmith Collective. (PROSE: The Vampire of Paris)
