The unnamed narrator is inspired to write The Scarlet Letter after discovering the scarlet letter and fragments of its story in an attic of the Custom House. He describes the novel as a tale of "human frailty and sorrow" and encourages the reader to heed its moral. Throughout the novel, the narrator favors Hester against the Puritans who persecute her. His writing often reads as if he's pained to have to tell such a sad story that involves the downfall of innocent victims at the hands of an oppressive society.
