Lady Susan 

Austen’s ‚most wicked tale, ‚ Lady Susan is a short epistolary novel by Jane Austen, possibly written in 1794 but not published until 1871. Lady Susan is a selfish, attractive woman, who tries to trap the best possible husband while maintaining a relationship with a married man. She subverts all the standards of the romantic novel; she has an active role, she’s not only beautiful but intelligent and witty, and her suitors are significantly younger than she is.
