Peace (The Unquiet Dead)

Mrs Peace was an elderly lady who died and was laid to rest at Sneed and Company. An alien Gelth took over her corpse, reanimating it. Mrs Peace then murdered her grandson and fled to Taliesin Lodge where Charles Dickens was giving a reading - the last place the real Mrs Peace had been intending to visit prior to her death. When the Gelth left her body to return to its gaseous form, Mrs Peace's body collapsed in the auditorium. (DW: The Unquiet Dead)
