Can it be Jane Austen?

In my self-declared quest of conquering the Austenian epistles, I discovered a work called Lady Susan which rather surprised me!  The heroine or shall I say anti-heroine is a widowed woman in her middle thirties who takes pleasure solely in discomfiting others.  This is no timid Fanny, lively Elizabeth, sensible Eleanor, or gentle Jane, this is a woman altogether unknown in all things Austen.  Perhaps Jane Austen is not the author, perhaps it is something of the ilk of the 'did Shakespeare write Shakespeare controversy.'  But no, the style, the wit, the wording is all Austen's.  Strangely, though I abhor the sentiments of the leading character, she may be one of the best written of all Austen's leading ladies!  It is a quick and interesting foray into a different part of the Austen universe, not entirely devoid of the charm which her other novels evoke.  Whatever else it may be, it proves again that Jane Austen can understand human emotion, thought, and behavior and put it on paper far better than most with advanced degrees in psychology!
