But to live in ignorance on such a point was impossible; or, at least, it was impossible not to try for information. Mr. Darcy had been at her sister’s wedding. It was exactly a scene, and exactly among people, where he had apparently least to do, and least temptation to go. Conjectures as to the meaning of it, rapid and wild, hurried into her brain; but she was satisfied with none.
– Jane Austen
Pride and Prejudice, Chapter 51. On learning from Lydia that Darcy was at her wedding, Elizabeth is filled with curiosity. Darcy is the last person she would expect to see at Wickham’s wedding as he "justly scorned" the man. She decides that she must find out, so she writes a letter to her aunt.
