 In some cases, a frame story presents the narrator as a character in an outside story who begins to tell their own story, as in Mary Shelley's "Frankenstein".First-person narrators are often unreliable narrators since a narrator might be impaired (such as both Quentin and Benjy in Faulkner's "The Sound and the Fury"), lie (as in "The Quiet American" by Graham Greene, or "The Book of the New Sun" series by Gene Wolfe), or manipulate their own memories intentionally or not (as in "The Remains of the Day" by Kazuo Ishiguro, or in Ken Kesey's "One Flew Over the Cuckoo's Nest").Henry James discusses his concerns about "the romantic privilege of the 'first person'" in his preface to "The Ambassadors", calling it "the darkest abyss of romance."
