Later that day, Mr. Utterson goes to Dr. Jekyll’s house. He is worried about his friend. Dr. Jekyll looks very sick and upset. Mr. Utterson asks if he is hiding Mr. Hyde. Dr. Jekyll assures him that he will never see or help Mr. Hyde again. He says that Mr. Hyde is safe and will not be caught.
Dr. Jekyll shows Mr. Utterson a letter from Mr. Hyde. In the letter, Mr. Hyde thanks Dr. Jekyll for his kindness and says he has a way to escape. Dr. Jekyll asks Mr. Utterson for advice on whether he should give the letter to the police.
Mr. Utterson takes the letter and promises to think about it. On his way out, he asks Dr. Jekyll’s servant, Poole, who delivered the letter. Poole says that no letters were delivered that day except by mail. This makes Mr. Utterson suspicious.
That evening, Mr. Utterson shows the letter to his clerk, Mr. Guest, who is an expert in handwriting. At that moment, a servant brings in an invitation from Dr. Jekyll. Mr. Guest notices that the handwriting on both documents is very similar, but the letters slope in opposite directions.
Mr. Utterson realizes that Dr. Jekyll wrote the letter from Mr. Hyde. He is shocked to think that his friend would forge a letter to cover up for a murderer. He locks the letter away in his safe, deeply troubled by this new discovery.
