explaining everything in case something happens to him before he can warn her in person. Aubrey does in fact die, and his letter does not arrive in time. Ruthven marries Aubrey's sister, and kills her on their wedding night, found drained of blood with Ruthven long gone into the night. Publication "The Vampyre" was first published on 1 April 1819 by Henry Colburn in the New Monthly Magazine with the false attribution "A Tale by Lord Byron". The name of the work's protagonist, "Lord Ruthven", added to this assumption, for that name was originally used in Lady Caroline Lamb's novel Glenarvon (from the same publisher), in which a thinly-disguised Byron figure was named Clarence de Ruthven, Earl of Glenarvon. Despite repeated denials by Byron and Polidori, the authorship often went unclarified. In the following issue, dated May 1, 1819, Polidori wrote a letter to the editor explaining "that though the groundwork is certainly Lord Byron's, its development is mine". The tale was first published in book form by Sherwood, Neely, and Jones in London, Paternoster-Row, in 1819 in octavo as The Vampyre; A Tale in 84 pages. The notation on the cover noted that it was: "Entered at Stationers' Hall, March 27, 1819". Initially, the author was given as Lord Byron. Later printings removed Byron's name and added Polidori's name to the title page. The story was an immediate popular success, partly because of the Byron attribution and partly because it exploited the gothic horror predilections of the public. Polidori transformed the vampire from a character in folklore into the form that is recognized today—an aristocratic fiend who preys among high society. The story has its genesis in the summer of 1816, the Year Without a Summer, when Europe and parts of North America underwent a severe climate abnormality. Lord Byron and his young physician John Polidori were staying at the Villa Diodati by Lake Geneva and were visited by Percy Bysshe Shelley, Mary Shelley, and Claire Clairmont. Kept indoors by the "incessant rain" of that "wet, ungenial summer", over three days in June the five turned to telling fantastical tales, and then writing their own. Fueled by ghost stories such as the Fantasmagoriana, William Beckford's Vathek, and quantities of laudanum, Mary Shelley produced what would become Frankenstein, or The Modern Prometheus. Polidori was inspired by a fragmentary story of Byron's, "Fragment of a Novel" (1816), also known as "A
