The Unreliable Narrator

The book's structure—an editor's narrative alongside Robert's first-person confession—creates conflicting accounts, forcing the reader to question the truth of events and the sanity or honesty of the narrator.

Robert's confession is marked by self-justification, selective memory, and a distorted moral framework, casting doubt on the truth of his account.

The editor questions the veracity of the manuscript and the sanity of its author, highlighting the theme of narrative unreliability.
