Literary Devices in The Canterville Ghost
Wilde's narrator interjects his own voice several times throughout the story. While we are not privy to the identity of the narrator nor their relationship to the family, this inclusive pronoun "we" demonstrates that the narrator identifies as English. Based on this, readers should understand that many of the narrator's observations of the contrasting cultures are exaggerated and done for humorous effect.
Wilde juxtaposes the beautiful, idyllic English countryside with the gloomy, ominous area around Canterville Chase to set the sinister tone of the location and play into traditional Gothic and horror story conventions.
Earlier, the narrator established himself as a fellow Englishman, and here we learn that he is recounting the events of the story based on what he learned firsthand from Mr. Otis. This style of narration gives the tale a sense of intimacy as if the narrator we sharing a very personal and true tale with his audience.
