Strange Case of Dr Jekyll and Mr Hyde

Stevenson structures the novella as a detective story with the wrong person doing the investigating: Gabriel Utterson, Jekyll's stolid, unimaginative lawyer, pursues the mystery of Jekyll's connection to the brutish Edward Hyde through legal documents, secondhand testimony, and locked doors, a method built for a world of comprehensible motives and civil procedure, and one entirely unequipped for the actual answer waiting at the end. That mismatch between investigative method and the truth being investigated is the book's real subject: Victorian respectability, embodied in Utterson's discretion and reluctance to think the worst of a friend, has no vocabulary for a colleague who has chemically split himself in two.

Jekyll's own account, withheld until the novella's final chapter, reframes everything that came before: Hyde was never a separate villain preying on Jekyll but a genuine, if concentrated, portion of Jekyll's own nature, the appetites and cruelties a respectable Victorian gentleman spends his whole social existence suppressing, given a body and a name of its own. Stevenson's insistence, through Jekyll's confession, that 'man is not truly one, but truly two' generalizes the case far past one doctor's experiment; Jekyll frames himself as simply the first person scientifically thorough enough to isolate what everyone else carries unexamined.

Hyde's physical smallness and the persistent, unplaceable sense other characters have that he is somehow deformed without any specific deformity anyone can name works as Stevenson's most efficient piece of symbolism: evil, in this novella, doesn't look monstrous in any conventional sense, it simply registers as wrong, an instinctive recoil the respectable Victorian eye can sense but not articulate, because the culture that produced Hyde has no honest language for naming the appetites he represents.

Stevenson reportedly wrote an entire first draft of the novella in three days during a bout of illness, dreaming much of the transformation scene, only to burn the manuscript after his wife Fanny objected that he had written a sensational shocker rather than the allegory the material deserved, and rewrote the whole thing from scratch in a similarly furious burst. The finished 1886 novella arrived amid, and helped fuel, wider Victorian anxieties about respectability's fragility, published only two years before the Jack the Ripper murders made the idea of a genteel Londoner concealing monstrous violence feel less like fiction than prophecy, which is part of why 'Jekyll and Hyde' entered the language almost immediately as shorthand for exactly that split.
