Not to be confused with a character with the same name, owner of Sabrina Fair (Hickory Dickory Dock)
In the novel A Murder is Announced, Mrs Lucas is the owner of Dayas Hall, where Phillipa Haymes works. She is described as "a large red-faced woman, carefully corseted".
She placed an advertisement in the Chipping Cleghorn Gazette for a Sheraton sideboard. Mrs Swettenham was sceptical that it was a genuine Sheraton.
