Summary chapter 4: Doctor Jekyll receives a letter.

Mr. Utterson goes to visit Dr. Jekyll, who looks extremely sick. Mr. Utterson asks if Dr. Jekyll is harbouring Mr. Hyde, and Dr. Jekyll swears that he will never see or contact Mr. Hyde again. Dr. Jekyll gives Mr. Utterson a letter written by Mr. Hyde. Mr. Utterson shares it with his head clerk, Mr. Guest, who just happens to be a handwriting expert. A messenger happens to deliver an invitation written by Dr. Jekyll. Mr. Guest declares that the two pieces of writing were written by the same hand. Mr. Utterson goes to bed very disturbed, convinced that Dr. Jekyll forged the letter from Mr. Hyde.
