What is the narrative scheme???

Much of Dr. Jekyll and Mr. Hyde is written in a brisk, businesslike, and factual way. Dry and forthright, the text often resembles a police report more than a novel. This colorlessness derives in part from the personality of Mr. Utterson, through whose eyes most of the story is told. Proper and upright, Utterson approaches the events with a desire to preserve any possible trace of orderliness or rationality in them. But the narrative’s dry manner also seems to arise from the text itself. The original title of the novel, The Strange Case of Dr. Jekyll and Mr. Hyde, as well as chapter headings—including “Incident of the Letter” and “Incident at the Window”—seem to reveal an attitude of scientific detachment within the very structure of the novel. When the text presents the letters of Lanyon and Jekyll almost as if they were pieces of evidence, the story itself seems to become something of a scientific proof.

The attitude of formality and propriety in the narrative contrasts sharply with its mystical and uncanny content. With its prim demeanor, the text could be seen as attempting to repress or deny the subject matter that lurks inside it. Stevenson implies that a similar dynamic is at work in the Victorian Britain that he inhabits and portrays. The phenomenon plays itself out on the individual scale as well, of course—the existence of Hyde in the novel testifies to the existence of an evil or primitive aspect within each one of us, just barely hidden beneath a polite, unruffled exterior.

Narrative scheme relates to how the story is told, who the narrator is and the point of view. The narrator is anonymous and speaks in the third person. Dr. Lanyon and Dr. Jekyll each narrate one chapter of the novel via a confessional letter. For most of the novel, the narrative follows Utterson’s point of view; in the last two chapters, Lanyon and Jekyll report their experiences from their own perspectives.
