Pride and Prejudice begins with a , by now, famous quote :
..." a single man in possession of a good fortune, must be in want of a wife."
Wickham is the opposite of this and schemes to himself marry into money. Elizabeth has been warned not to get too close in her friendship with Wickham, although she claims that she is not "in love" with him. She promises Mrs Gardiner that, on her "honor" she will try to do the "wisest " thing. Mrs Gardiner, unlike Elizabeth, has recognized Wickham's possible ulterior motives and "turned on " charm.
When Elizabeth is made aware of his changed allegiance (ch 26) (vol 2.Ch 3), she satisfies herself with thoughts that Wickham would naturally have chosen her but his good looks would never be enough to sustain him and so he had had to associate himself with a woman whose "most remarkable charm " is a recently inherited ten thousand pounds.
make that volume 2 Chapter 3
its chapter 26, what a worthwhile first question lol
