I told him I fared the worse for being taken in the prison for one Moll Flanders, who was a famous successful thief, that all of them had heard of, but none of them had ever seen; but that, as he knew well, was none of my name. (1099)
While her fake identities have been a blessing for the most part, enabling her to move around London committing crimes without suspicion, once she is caught, being known as Moll Flanders is just about the worst thing possible. Her fellow thieves resent her, and law enforcement sees her as nothing but a legendary criminal. It seems Moll doesn't think she is such a thing, but based on her actions, we're siding with the police on this one.
