Final answer:
The old lady from 'To Kill a Mockingbird' who overcomes her morphine addiction is Mrs. Henry Lafayette Dubose. She demonstrates tremendous personal courage and leaves a symbol of her gratitude to the Finch children.
Step-by-step explanation:
The old lady you are referring to, who beats her morphine addiction, is a character from Harper Lee's novel To Kill a Mockingbird. This character is Mrs. Henry Lafayette Dubose, a cantankerous elderly woman who lives near the Finch family. Despite her difficult demeanor and the conflict she has with the main characters, Scout and Jem, she is a central figure in the theme of courage within the novel. As Jem learns, Mrs. Dubose had made a goal to free herself from her morphine addiction before she died, and she achieved this with the unseen support of the Finch children, to whom she left a single white camellia flower as a symbol of her gratitude.
