Dolores Claiborne, an opinionated 65-year-old widow living on the tiny Maine community of Little Tall Island, is suspected of murdering her wealthy, elderly employer, Vera Donovan. The novel is presented as a transcript of her statement, told to the local constable and a stenographer. Dolores wants to make clear to the police that she did not kill Vera, whom she has looked after for years, but does confess to orchestrating the death of her husband, Joe St. George, almost 30 years before. Dolores's confession develops into the story of her life, her troubled marriage, and her relationship with her employer.
