Gabriel John Utterson, a lawyer, is on his weekly walk with his cousin, Richard Enfield. During that walk, they reach a door leading into a rather large house, and this motivates Enfield to tell Utterson of an encounter he had seen some months ago while coming home late at night between a man and a young girl. The man, a sinister figure named Edward Hyde, and a young girl, who has run to get a doctor, accidentally bump into one another, but Hyde proceeds to trample her. Enfield chases after Hyde, brings him back to the scene, and, after the doctor assures them that the girl is okay, though frightened, joins with the girl's family in forcing Hyde to pay £100 to avoid the scandal they will otherwise spread for his despicable behaviour. Hyde leads them to the building in front of which Enfield and Utterson have now paused, where he disappears, and re-emerges with £10 in gold and a cheque for the rest, drawn on the account of a reputable gentleman. (This gentleman is later revealed to be Dr. Henry Jekyll, one of Utterson's clients and old friends.) Jekyll had recently so draughted his will as to make Hyde the sole beneficiary in case of his death or—much to Utterson's disturbance—his disappearance for more than three months. This development concerns and disturbs Utterson, who makes an effort to seek out Hyde, fearing that Hyde is blackmailing Jekyll. When he finally sees Hyde, the latter's ugliness, as if deformed, amazes Utterson. Although Utterson cannot say exactly how or why, Hyde provokes an instinctive feeling of revulsion in him. Much to Utterson's surprise, Hyde willingly offers Utterson his address. After one of Jekyll's dinner parties, Utterson stays behind to discuss the matter of Hyde with Jekyll. This causes Jekyll to turn pale, which Utterson notices. Yet Jekyll assures Utterson that everything involving Hyde is in order and that Hyde should be left alone...
