First appearance: Book I: The Problem
As a major figure in The Leavenworth Case, Mary Leavenworth is not background color—the story leans on what they do once the chapter opens.
Mary Leavenworth is present in the household and becomes a person of interest.
Mary Leavenworth is the beautiful, socially gifted niece whose composure under suspicion strikes observers as either innocence or extraordinary self-command. She deflects inquiry with sweetness and retreats behind notes and headaches when pressed, leaving the narrator unsure whether she is a victim, an accomplice, or something worse. Her evasions and her secret ties to Henry Clavering make her the emotional and moral puzzle at the center of the investigation.
