The writer of the universally popular Pride And Prejudice explores another angle of the conflicts of dealing with life as it is dealt out - wealth and relative status, temptation and opportunities, family and relationships, extended family and relatives, and love that never might be attained.Above all are rectitude and character and values, to be never lost whatever the temptation.
If one never knew anyone of this sort, one would think the character is entirely invented. At that it is not that uncommon to come across men who deal with their own children, especially daughters, this cruelly or worse, but they are excused or even pressured to be this cruel and admired for it in various cultures (not excepting west or US for that matter) while women are usually this cruel with children of other women, say a lover's wife or a sister in law. But the character therefore is entirely possible, especially in an era when a woman could only obtain wealth and consequence by marriages her own and her relatives'; and the only area she could use her mind however sharp was in fields related to intrigues of social sort, marriages, love affaires, and so on, especially gossip and vile gossip about other women. This unfortunately is what far too many women and even men use their minds for, even now, for sport and not for want of subjects that could use the sharp minds. Sometimes it is the heart of such a gossiper and mud thrower that is at fault seriously in that destroying another person is the pleasure, and use of mind and other facilities is merely a means. Lady Susan comes as a surprise therefore not because of the subject but the author who chose to write it, since Jane Austen usually is as clear as a sunny day in desert about virtues and vices, and condemning not only the latter but even faults of character that might seem only human today but do lead to follies or tragedies even today often enough unquestionably. Here Austen chooses the letter form prevalent in her time, and avoids commentary, except in letters of another character, giving equal voice to two opposite characters as it were. The story ends well as all Austen tales do to reward virtue, protect innocent and punish vice or folly only in measure. A window as always to her time, and informative in that as well.
