Madame Deuteronomy
From Tardis Wiki, the free Doctor Who reference
Madame Deuteronomy was the owner of the Théâtre de Fantasie. She could see into people's minds as her act. She convinced Henry Gordon Jago to book her act for his theatre. George Litefoot thought that she had something to do with the recent spate of murders. She murdered people to feed the being that was in her theatre. (AUDIO: The Theatre of Dreams)
