What are the literary devices used in the short story a rose for Emily?

Faulkner uses the plotting of A Rose For Emily by creating five distinct sections, each which describe a time from the present to the past where Emily's behavior around her father and her suitors is seen as increasingly mysterious and scandalous by her townspeople. Each section dramatically leads up to the final scene where the reader is left to realize that there is a suggestion of necrophilia, something that has been alluded to throughout the story.
