This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book shows how the persona of Lord Byron became the effective vehicle for the vampire of fiction as a transformed Gothic mode. It analyses Le Fanu's 'Carmilla', with its seductive lesbian vampire, alongside his vampiric tale 'The Mysterious Lodger'. The book provides a luminous account of early vampire cinema as a 'Kingdom of Shadows', digging up lost cinematic texts which should be better known. It explores the Dracula's exclamation 'I, too, can love', and also examines the complex intertextuality involved with Dracula and Twilight, via Francis Ford Coppola and Anne Rice, drawing on adaptation studies. In addition, the book discusses the autonomy of the Undead, plotting an unusual argument drawing on theology and linking the monstrous with ideas of human agency and moral responsibility.
