Miss Havisham sends a note to Pip to meet her. Pip reaches Miss Havisham's house and the first thing she asks for is to forgive her for raising Estella ruthless and heartless. She asks him to sign below her name seeking forgiveness and he accepts it unconditionally. Finally, she pulls her chair too close to the fireplace and her worn out clothes catch fire and she runs shrieking, "with a whirl of fire blazing all about her" and soaring above her head. Pip tries to help her with his coat by enclosing her and uses the tablecloth to smoothen the flames. Finally, the physician declares that Miss Havisham is dead.
During Pip's last visit to Miss Havisham, she reflects on the damage that she caused him, and asks for his forgiveness, which Pip gladly gives her. However, in a tragic turn of events, Miss Havisham walks too close to the fireplace and her wedding dress catches on fire. Despite Pip's efforts to help her, she is burned and dies.
