A report of a most alarming nature reached me two days ago. I was told, that not only your sister was on the point of being most advantageously married, but that _you_--that Miss Elizabeth Bennet would, in all likelihood, be soon afterwards united to my nephew--my own nephew, Mr. Darcy. Though I _know_ it must be a scandalous falsehood, though I would not injure him so much as to suppose the truth of it possible, I instantly resolved on setting off for this place, that I might make my sentiments known to you.”
