i think you mean Miss. Pross. She is Lucie's utterly devoted guardian, and she does everything for her. Miss. Pross is a "wild looking woman" and is seriously protective of her "Ladybird", who is Lucie Manette.
Miss PROSS is Lucie's maid that takes care of her. She has red hair, which the author uses as a symbol of her fierce devotion and loyalty to Lucie. She is, in many respects, the opposite of Lucie. She is fiery, quick to stand in defence, and is shrewd and calculating when it comes to her duties.
