One type of main character in Glaspell's short stories is the woman who is dealing with a difficult situation within a marriage or family. She has to navigate through the expectations of her husband, family members, and society at large. Another type could be the male character who, while not always the focus, represents the traditional values and power that the female characters are trying to break free from.
In 'A Jury of Her Peers', Mrs. Hale and Mrs. Peters are main characters. They are the women who accompany their husbands to the crime scene and end up having a different view of the situation compared to the men. They are observant and empathetic.
