Let's All Kill Constance is a 2002 mystery novel by Ray Bradbury. Narrated by an unnamed Los Angeles writer and set in 1960, it chronicles an unexpected visit from aging Hollywood actress Constance Rattigan who gives him two death lists of once-famous people — with Constance's name on one of them, and the gradual unraveling of the mystery by the narrator with the help of private investigator Elmo Crumley. Let's All Kill Constance is a sequel to Bradbury's Death Is a Lonely Business (1985) and A Graveyard for Lunatics (1990).
