There's only one real instance of foreshadowing in this novel. This is when Elizabeth is visiting Pemberly with her Aunt and Uncle (when she thinks that Darcy isn't there) and she allows herself to admire it and come to love it. She even allows herself to muse that she might have been mistress of it had she accepted the odious Darcy's proposal. Ironically...of course....she does become the mistress of it.
