Mr. Utterson and Mr. Enfield go on Sunday walks, Enfield tells Utterson about a strange story with a hideous creature-like man named Mr. Hyde. He says that he saw Hyde cripple and trample a girl.
Utterson, is troubled when he takes the will of his friend Dr Jekyll from his safe. It contains a worrying instruction: in the event of Dr Jekyll's disappearance, all his possessions are to go to Mr Hyde. Utterson goes next door to warn his friend, Jekyll, against Hyde, but is told by the servant, Poole,that Jekyll is out and the servants have all been instructed by Jekyll to obey Hyde.
Mr. Utterson can’t get the story of Mr. Hyde out of his mind so he goes to find Dr. Jekyll will (since Utterson is his lawyer). In it it states important and disturbing information that makes Utterson fear for his friend, Dr. Jekyll's, life.
Mr. Utterson thinks it is madness and goes to find Dr. Lanyon, a friend of Dr. Jekyll, hoping that he knows where he is at that time, but cannot find him. Utterson gets a scary nightmare that night about a faceless man running down a child.
Eventually, Mr. Utterson encounters Hyde and introduces himself as a friend of Jekyll. Utterson asks Hyde to show his face and he does. Mr. Utterson understands why people cannot pinpoint what is exactly wrong with him, but he does conclude how Hyde is very ugly.
Utterson talks about how Dr. Jekyll’s will makes him concerns and he responds by saying that he knows this because Mr. Utterson has brought it up before. When Mr. Utterson mentions the name “young Hyde” it makes Dr. Jekyll turn pale.
