Varney the Vampire; or, The Feast of Blood, the classic 1847 serial by James Malcolm Rymer with Thomas Preskett Prest

Varney the Vampire is 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 "penny dreadful" pamphlets. This edition is the third of a three-volume series collecting the sprawling epic and collects the final 100+ chapters of the epic.
Despite its inconsistencies, Varney the Vampire is more or less a cohesive whole. It is the tale of the vampire Sir Francis Varney and introduced many of the tropes present in vampire fiction recognizable to modern audiences to this day.
