The Girl was a vampire-like alien responsible for many deaths in a village in England.
The Girl became friends with Connie Bryde and entered her house to join her and the Eighth Doctor in a meal. The Girl left the house at midnight and called to Tom Bledlow while he was asleep. When he joined her, the Girl began to drink his blood. The Doctor killed the Girl by breaking her neck. Before the Girl could be buried, her body had turned into fine, black ash. (PROSE: Evergreen)
