Utterson agrees to keep it for him. When leaving the house, Utterson discovers from the butler that nothing was delivered that day, and Utterson begins to grow uneasy. With an assistant, he compares the writing on Mr Hyde’s supposed letter with Jekyll’s handwriting: they are similar. Utterson is angry that Jekyll should have forged a letter for a murderer.
More detailed summary
Utterson calls on Jekyll, whom he finds in his laboratory looking deathly ill. Jekyll feverishly claims that Hyde has left and that their relationship has ended. He also assures Utterson that the police shall never find the man. Jekyll then shows Utterson a letter and asks him what he should do with it, since he fears it could damage his reputation if he turns it over to the police. The letter is from Hyde, assuring Jekyll that he has means of escape, that Jekyll should not worry about him, and that he deems himself unworthy of Jekyll’s great generosity. Utterson asks if Hyde dictated the terms of Jekyll’s will — especially its insistence that Hyde inherit in the event of Jekyll’s “disappearance.” Jekyll replies in the affirmative, and Utterson tells his friend that Hyde probably meant to murder him and that he has had a near escape. He takes the letter and departs.
On his way out, Utterson runs into Poole, the butler, and asks him to describe the man who delivered the letter; Poole, taken aback, claims to have no knowledge of any letters being delivered other than the usual mail. That night, over drinks, Utterson consults his trusted clerk, Mr. Guest, who is an expert on handwriting. Guest compares Hyde’s letter with some of Jekyll’s own writing and suggests that the same hand inscribed both; Hyde’s script merely leans in the opposite direction, as if for the purpose of concealment. Utterson reacts with alarm at the thought that Jekyll would forge a letter for a murderer.
