Miss Lanchester was a resident at Mrs Hutchings' guest house.
She scolded the First Doctor for eating ice cream at his age.
When Jeff Atkins and his Pakistani wife, Ujwala, arrived at the guest house with their son Craig, Miss Lanchester disapproved and told Mrs Hutchings that she would be moving in with her friend.
Like Mrs Hutchings and her guests, Miss Lanchester was unaware that it was actually 1999, and that an alien posing as a guest, Mr Prentice, had placed the guest house in a kind of stasis so it would always be 1933 in Keelmouth. The Doctor and Prentice set things to right, and Miss Lanchester and the other residents had to adapt to living in 1999. (PROSE: Bide-a-Wee)
