Mr. Utterson was confused on why all of Jekyll's stuff would go to an evil man.
Two cousins, Mr. Utterson and Mr.Einfield went on their weekend walk together when Mr. Einfield recalled a story that was connected to the strange door of this strange building. Mr. Einfield had seen this evil monsterish looking man trampled a girl! The man was not sorry for trampling the girl and only wished to pay her parents and get on with his life. The evil mans name was Mr.Hyde.
That evening when Mr. Utterson got home he opened his safe and got out the will of his really good friend and client Dr. Jekyll. He studied the will and noticed that all of Dr.Jekyll's stuff was to go to Mr. Hyde. The will clearly stated, "...All his possessions were to pass into the hands of his 'friend and benefactor Edward Hyde'."(Stevenson 2)
The evil Mr. Hyde struck terror again and killed a congress man. A maid in the building witnessed the crime and called the cops telling them Hyde had killed a man. Mr. Utterson had the sad task of identifying the body.
Mr. Utterson gets word that Dr.Jekyll is sick and goes to see him.
Utterson found Hyde's dead body on the floor with a note on the table.
The note explained that Dr. Jekyll was experimenting on himself and split the good and evil personality inside of him. He lost control of who he became and confessed that he killed the congressman, he didn't want to live as Hyde anymore and couldn't switch back to Jekyll and the only way to be happy as Jekyll was to die.
