Louise is a young woman living in the 1890s who suffers from "heart trouble," requiring her family and friends to treat her with extreme delicacy. Described as having a fair, calm face that suggests repression but also inner strength, she values her own emotional authenticity. When she receives tragic news, she insists on isolating herself in her room, revealing a deeply independent streak and a rich inner life that pushes against the era's social expectations.

Brently is Louise's husband, whose reported involvement in a severe train accident serves as the inciting incident of the story. He represents the typical 19th-century husband whose societal position inherently grants him control over his wife's life and choices. Though he is not depicted as an unusually cruel partner, his presence defines the boundaries of Louise's domestic existence.

Josephine is Louise's sister and acts as a representative of traditional 1890s social standards. She conforms to the expectations of how women should behave and process grief. Deeply concerned for her sister's physical well-being due to a known heart condition, Josephine assumes a caretaking role and worries when Louise isolates herself behind a locked door.

Richards is Brently's friend who works closely with the local newspaper. He embodies the traditional notion that men are responsible for shielding women from harsh realities. Upon hearing reports of a tragic accident, he takes it upon himself to confirm the details via a second telegram before hurrying to ensure the news is delivered to Louise as gently as possible.
