In the novel The Mirror Crack'd from Side to Side, Miss Grundle works at Biddle & Russell, the house agents and valuers in St. Mary Mead, which is also where Arthur Badcock works. Florrie West also works there. Miss Grundle is at least fifty years old, and is described as being "plain as a haystack", and so Inspector Cornish does not think it likely that Arthur Badcock would want to marry her after the death of his wife.
