Document 4: Dracula: Dracula is an 1897 Gothic horror novel by Irish author Bram Stoker. It introduced Count Dracula, and established many conventions of subsequent vampire fantasy.

Document 5: Lucy (novel): "Lucy" retains the critical tone of "A Small Place" but simplifies the style of Kincaid's earlier work by using less repetition and surrealism. The first of her books set completely outside the Caribbean, "Lucy", like most of Kincaid's writing, has a strong autobiographical basis. The novel's protagonist, Lucy Josephine Potter, shares one of Kincaid's given names and her birthday. Like Kincaid, Lucy leaves the Caribbean to become an au pair in a large American city. At nineteen, Lucy is older than previous Kincaid protagonists, which lends the book a more mature and cynical perspective than in her previous fiction. Still, Lucy has pangs of homesickness and unresolved feelings about her mother, and she has never lived on her own or seen much of the world. With plenty of room for growth and Lucy becoming a photographer, the story takes the form of a "künstlerroman", a novel in which an artist matures.

After failing to kill Dracula at an underwater volcano, Ericka moans about being unable to get him. Dracula's friends hear this, and thinking that Ericka likes him, inform Dracula about what they heard. Dracula nervously asks Ericka out on a date, and she accepts since she sees this as another chance to kill the vampire. However, as they dine on a deserted island, Ericka begins to fall in love with Drac, after they learn about each other's pasts.

Each night, Viago, Vladislav, and Deacon prowl the streets of Wellington searching for people to kill, but they must stay in the flat during the day to avoid sunlight -- which is lethal to vampires -- and as such have not adapted to 21st - century life. Deacon has a human servant (familiar), Jackie, who runs errands for the vampires, but she is frustrated that Deacon will not turn her into a vampire as he has promised. Jackie leads her ex-boyfriend Nick to the vampire's flat so they can drink his blood; he escapes before they can kill him, but as he leaves the flat, Petyr attacks him and later turns Nick into a vampire.
