Varney the Vampire; or, The Feast of Blood [EPUB ebook] 

Set during the reign of King George II, this gruesome tale concerns the persecution of the Bannerworth family by Sir Francis Varney: a vampire who has developed the habit of creeping into the Bannerworth home and sucking the blood of their daughter, Flora. Varney is presented sympathetically, a victim of circumstances as he tries to save himself, and his victims, from such dreadful acts.
