I am always troubled by Mrs. Smith and her unshared knowledge of Mr. Elliot. If what he did was really so bad, why didn't she warn Anne as soon as she heard rumors of a relationship. Why recommend Mr. Elliot, knowing what sort of man he was. What kind of friend does that? At least LR had no idea of his mercenary character when she promotes him to Anne. The sudden turn in Mrs. Smith once she realizes Anne is not going to marry Mr. Elliot really seems to indicate she should not have been encouraging Anne.
Is there anyone who likes Mrs. Smith who can explain the behaviour?
