by Charles Dickens
Molly is Jaggers' maid and also—dun dun dun!—Estella's mother/Magwitch's wife. Jaggers defended Molly years before when she had been accused of murdering a woman in a barn out of jealousy. He got her off by pointing out that she's teeny-tiny and couldn't possibly have killed the other woman, but she has incredibly strong hands and wrists—which Jaggers enjoys pointing out in an extremely creepy manner. Molly was cured of a wild temper after her trial (the fear of being executed will do that to a person) and agreed to work for Jaggers immediately.
