Why did The Strange Case of Dr. Jekyll and Mr. Hyde make Robert Louis Stevenson famous with ordinary readers?

The Strange Case of Dr. Jekyll and Mr. Hyde resonated with 19th-century readers because it masterfully explored the concept of the "double," a theme that was widely popular at the time. By depicting the dichotomy between a respectable public persona and hidden, baser desires, the novella served as a powerful representation of the Victorian "bifurcated self".1

The story captured the public imagination by addressing the tension between outward gentility and inward lust, suggesting that human propensities for good and evil exist in varying measures. This psychological exploration gained even greater resonance following the 1888 Jack the Ripper murders, as the public used Stevenson’s framework to interpret the era's new, urban forms of violence. Ultimately, the work succeeded by combining elements of horror and suspense with a profound moral diagnosis of the human condition, cementing Stevenson's reputation as a writer of originality and power.12
