Jack Dupre

Jack Dupre was a magican who conducted a ghost walk from 7pm onwards in New Orleans. Jack followed the Eighth Doctor when he was touring a museum and when the Doctor was alone, Jack knocked him unconcious. He then tortured the Doctor in an attempt to summon a demon from within him, he was later shocked to find that he was an alien. Jack succeeded in summoning the Demon from the Doctor and created a magic circle using Graveyard dust to protect himself from it. The Doctor blew some of the dust away and broke the circle, the demon then ate Jack. (EDA: The City of the Dead)
