The Horla by Guy de Maupassant is an early vampire story by one of the great writers of all time. The story focuses on the difficulty a man has in accepting the existence of the vampire and the devastation caused by the the creature. Contrary to the current acceptance of the existence of the vampire by so many, during the 19th century almost all people didn't believe in vampires. Too bad.
