Unfamiliar with Varney the Vampire?
Excerpted from the Wikipedia entry:
Varney the Vampire or The Feast of Blood was a mid-Victorian era gothic horror story by James Malcolm Rymer (alternatively attributed to Thomas Preskett Prest), which first appeared 1845–47 in a series of pamphlets generally referred to as penny dreadfuls because of their inexpensive price and typically gruesome contents. It was published in book form in 1847. It is of epic length: the original edition runs to 868 double columned pages divided into 220 chapters.
Despite its inconsistencies, Varney the Vampire is more or less a cohesive whole, utilizing or introducing many themes and conventions recognizable to modern audiences….Varney was a major influence on later vampire fiction, particularly Dracula (1897) by Bram Stoker.
This is also the first example of the “sympathetic vampire,” a vampire who loathes his condition but is nonetheless a slave to it. This archetype has been widely exemplified, notably by such characters as Barnabas Collins in the TV soap opera Dark Shadows, Louis de Pointe du Lac in Anne Rice’s Interview with the Vampire, Kain in Legacy Of Kain and Angel from the show Buffy the Vampire Slayer.
