I recently discovered this lost volume written by an eccentric but impeccable master researcher of the occult, witchcraft and vampirism in 1928. His name is Montaque Summers and he has written a chilling masterpiece about the origin, nature and reproduction of vampires as though they really exist. Perhaps this is what gives this book so much weigh, especially considering Summers annotated sources and footnotes. This 136-page e-book is worth reading for those who have no problem with the dark of night and creatures that may exist beyond our worst nightmares.
