The literature of the 19th-20th century featured strong female characters who served as role models for oppressed women in patriarchal societies. Female detectives, often seen as unconventional, emerged as a response to the feminist movement. This thesis explores the first wave of feminism and its impact on literature, examining how it influenced attitudes towards duties and roles. It also highlights the struggle for women to find their place among men and their role in law enforcement. The series Miss Scarlet and the Duke illustrates the ideal woman image in the 19th-20th century and draw attention to her aim and methods. The thesis aims to prove that women are equally useful in law enforcement due to their unique characteristics.
