Chapter 1

While on a stroll, Mr. Utterson and Mr. Enfield, two respectable English gentlemen, come upon a building that Enfield relates a story about. One evening, Enfield explains, he witnessed and apprehended a hideous man who had just trampled over a girl, and when cornered by an angry mob, the man entered the building and gave the crowd a check bearing the name of a respectable man. Enfield eventually reveals the culprit’s name to be Hyde, which leads Utterson to surmise who the check belonged to, and the two men speculate that Hyde must be blackmailing the man.

Utterson reads Jekyll’s letter that details his early desires to separate the good and evil nature of man, and his experiments to create the formula that would eventually give birth to Hyde. Though at first Jekyll took joy in living as Hyde, he realized that the more he took the formula the likelier the possibility that he would remain as Hyde forever.
