Chapter 5
Utterson goes to Jekyll's house, and up to his cabinet (bedroom), where he finds Jekyll sick, not even getting up to say hello. Utterson tells Jekyll that Danvers was a client of his and asks if Jekyll is hiding Hyde. Jekyll declares that Hyde is safe, and Utterson finds it strange that Jekyll can be so sure. Jekyll gives Utterson a letter written by Hyde where he apologizes to Jekyll for causing so much trouble, although Jekyll is afraid that the letter might harm his own reputation. Utterson finds this a selfish consideration. Utterson believes that Hyde told Jekyll how to make his will, and tells Jekyll that he is lucky because Hyde was going to kill him. Jekyll is upset and says only, Oh what a lesson I have learned!” Jekyll tells Utterson that the letter came to him by delivery, not through the mail, but as Utterson leaves, he asks the servant, who tells him that no letters came by delivery...
That night, Utterson has his assistant, Mr. Guest, over to look at the letter, so that he might hear his thoughts on the matter. Guest notices that Hyde's handwriting is the same as Jekyll's, except slanted differently. Utterson cannot image why Jekyll would forge Hyde's letter for him.
