The traditional gender roles assigned to women in literature were crushed by many women writers who depicted women in unconventional roles and a major writer among them is Agatha Christie. In detective fiction, majority of leading characters have always been men and women used to be the victims of the crime. But Agatha Christie broke away from this conventional trend in crime fiction and created intelligent female detectives. She gave heroic attributes to women characters and proved that they are also capable of achieving the goals like men. She fought Victorian literary conventions, which depicted women as weak and dependent on men, to bring out females with sharp and brilliant minds. But she was strongly criticized by her contemporaries for her stereotypical female characters. This paper analyses the effective portrayal of the strong and independent female detectives and new women of 1920’s in Christie’s work. This paper also aims at finding the feminist traits in Christie’s women characters and their role in shattering the conventional stereotypes of women in crime fiction.
