OK, let's imagine Jane Austen as the author of Dracula. True, William Wilkinson's An Account of the Principalities of Wallachia and Moldavia https://books.google.com/books?id=RogMAQAAMAAJ&printsec=frontcover (from which Stoker apparently got his knowledge of the Voivode and of the word "Dracula"[1]) was not published until 1820, and Jane Austen died in 1817; but we can have her live a few more years..
("Wickham, in turn, bears a passing resemblance to Lord Ruthven in Polidori's Byron rip-off: They both feed on virgins and have a penchant for disastrous gambling, a tendency Regina Jeffers makes even more monstrous in her fiendish version of Pride and Prejudice. Janet Mullany, author of the forthcoming Immortal Jane Austen, concurs: "There are characters in Austen's novels who are clearly vampires—Willoughby, the Crawfords, and Wickham," she revealed in an interview. "They exploit and feed off others, they're amoral and handsome and they wreak havoc. So obviously Austen knew about vampires as well as sex."" https://www.chronicle.com/article/See-Jane-Bite/64585)
[1] " Dracula in the Wallachian language means Devil. The Wallachians were, at that time, as they are at present, used to give this as a surname to any person who rendered himself conspicuous either by courage, cruel actions, or cunning." https://books.google.com/books?pg=P...eQ&id=RogMAQAAMAAJ&ots=JKN1lXiRU0&output=text
