Curley's wife

Generally considered to be a tramp by the men at the ranch, Curley's wife is the only major character in Of Mice and Men whom Steinbeck does not give a name. She dislikes her husband and feels desperately lonely at the ranch, for she is the only woman and feels isolated from the other men, who openly scorn her. She still holds some small hope of a better life, claiming that she had the chance to become a movie star in Hollywood, but otherwise is a bitter and scornful woman who uses sex to intimidate the workers. Lennie accidentally murders her.
