Great Expectations has more secrets than a season of Pretty Little Liars. From the source of his fortune to the mystery of Estella's parentage—not to mention all the minor secrets, like Wemmick's secret second self or the fate of the pork-pie—the novel is full of people lying, covering up their tracks, and misdirecting the truth. Is honestly always the best policy? Or do some of these lies end up working for good?
Jaggers is the only consistently honest character in Great Expectations, even if he is a lawyer.
By deceiving himself, Pip brings about his own ruin.
