Miss Hudson is the landlady of 221B Baker Street, housing Sherlock Holmes and John H. Watson. She appears as a young adult with long brown hair often braided, dressed in a pink gown and white apron over the skirt. Post-timeskip, her attire covers her arms and neck more fully, contrasting earlier exposed skin and rolled sleeves, while a floral brooch remains fixed on her chest. Confident yet frequently stressed, she balances inherent kindness with sharp frustration toward Sherlock Holmes over his unpaid rent, disappearances, and self-isolation. Despite conflicts, she harbors deep concern for his safety. Acts of compliance from Sherlock spark genuine happiness in her, and her hospitality extends warmly to Watson and newcomers like Mary. Emotionally perceptive, she detects Sherlock’s jealousy regarding Mary and gauges sincerity in others’ words. She reacts strongly to age references near thirty, insisting she is "forever seventeen," and is easily flattered or distracted by compliments about her looks. Her background reveals direct involvement in Sherlock’s living arrangements: during a rent dispute, a friend suggests a flatmate to share costs. Sherlock proposes candidates—an actor deemed financially unstable, a prostitute expected to bring clients home, and a homeless man unable to pay—all rejected by her. She approves John H. Watson after discerning his good character, recognizing her friction with Sherlock coexists with familial affection. This dynamic cements her as the household’s stabilizing force. Consistent traits include aspirations like buying an entire Harrod’s clothing floor or traveling abroad if financially able, hinting at interests beyond landlady duties. Her interactions blend comic exasperation and underlying care throughout her appearances.
