On the same day of the murder, Mr. Utterson makes his way to Dr. Jekyll's house, and meets with him in his laboratory. Utterson and Jekyll discuss the unfortunate news that Sir Danvers Carew is dead, presumably killed by Mr. Hyde. Jekyll swears that he is not hiding Hyde and that he is, "done with him in this world." Jekyll also claims that he has received a letter from Hyde, which he shows to Utterson. The letter thanks Jekyll for his kindness and urges him that he need not worry for his safety, as he has a sure means of escape. Dr. Jekyll does not have the envelope, and claims that he burned it after it was hand delivered. Jekyll asks Utterson what to do with the letter, as he is concerned that his reputation will be damaged if he hands it over to the police. Utterson agrees to hold on to the letter, and tells Jekyll he is glad that Hyde has disappeared, as Jekyll's life was most likely in danger. When leaving the house, Jekyll's butler Poole tells Utterson that nothing was delivered that day, and Utterson begins to grow suspicious.
Upon returning to his office, Utterson receives a dinner invitation from Jekyll. When the letter arrives, Utterson's assistant, Mr. Guest, is examining the writing on the letter supposedly from Hyde. Mr. Guest instantly recognizes that the same individual wrote both letters, although the writing on the Hyde letters appears to be slanted in a certain direction. Utterson angrily assumes that Jekyll has forged a letter for a murderer.
