In the fog-bound streets of Victorian London, the sober lawyer Mr. Utterson grows troubled by a sinister figure named Edward Hyde, a man who radiates cruelty and inspires loathing in all who meet him, and who has lately committed an act of shocking violence. What disturbs Utterson most is Hyde's strange hold over his own dear friend, the respectable and well-loved Dr. Henry Jekyll, who has inexplicably bound his fortune and his fate to this loathsome stranger. Determined to understand, Utterson begins to dig. Stevenson's chilling 1886 mystery draws its reader toward a secret no one could have imagined.
