Miss Havisham is a character from the novel Great Expectations by Charles Dickens. She is one of the most famous spinsters in literature, having been stood up by her fiancé on their wedding day.  She is so disturbed by the experience she remains forever more confined to her house, still wearing her wedding dress and reminiscing about the marriage that never was.  The character of Norma Desmond in the film Sunset Boulevard was inspired by her.
