Mountford was a friend of Beatrice. She consoled Beatrice when her father died. She was present when a spectral child appeared in the house in 1922. She warned the Fourth Doctor and Romana II not to provoke the spirits. She thought that it was strange to have a second séance. Romana thought it was strange that she left so quickly. She was a spirit of the dead. (AUDIO: The Haunting of Malkin Place)
