What he told me was merely this: that he congratulated himself on having lately saved a friend from the inconveniences of a most imprudent marriage, but without mentioning names or any other particulars, and I only suspected it from believing him the kind of young man to get into a scape of that sort and from knowing them to have been together the whole of last summer.

– Jane Austen

Pride and Prejudice, Chapter 33. Colonel Fitzwilliam reveals to Elizabeth that it was Mr. Darcy who broke up the courtship of Jane by Charles Bingley because he felt it wasn’t a wise match. There were strong objections to the lady, the colonel said. This is an example of dramatic irony, as the colonel doesn’t realize that he is talking to Jane’s sister.
