Victorian gentlemen were expected to uphold strong moral standards and hide any behaviors deemed improper according to their social class and reputations. As members of the upper classes, they held positions such as doctors, lawyers, and clergy, and tried to maintain an appearance of respectability while secretly engaging in vices like drinking and visiting brothels. Stevenson was interested in exploring the dual nature of man and how gentlemen hid their darker sides to protect social standing through his story of Dr. Jekyll and Mr. Hyde.
