The structure of ['Dr. Jekyll and Mr. Hyde'] follows a path as indirect and elusive as its multiple narrative voices. With its obliquely recorded incidents, its eyewitness accounts and sealed confessions, it resembles...a [police detective's] casebook--a collection of gathered clues, fragments, through which the clever detective may be able to...project a complete narrative. Perhaps one of the most compelling aspects of this novel [of ten chapters] is that, in fact, there's so much left here for [the reader] to fill in, so many scenes that [the reader] can only imagine. Such a structure creates fertile ground for allegory [a story with symbolic meaning] hunters, and there are indeed many convincing interpretations of this novel.
