 Now one afternoon Mr. Utterson visits Dr. Jekyll and he goes into his private study and sits down. Now Mr. Utterson notices that Dr. Jekyll looks particularly sick and he asks him directly are you covering up for Mr. Hyde? Dr. Jekyll says no and that Mr. Hyde is already gone never to be seen again. And Dr. Jekyll then showed Mr. Utterson a letter that Mr. Hyde wrote. Mr. Utterson looks at that letter and decides to keep it. Then he goes over to Mr. Pool and says did this letter arrive in the mail today? Mr. Pool said no we didn't get any mail today. Mr. Utterson began to suspect that maybe Mr. Hyde wrote this letter in Dr. Jekyll's study. So he decides to go seek his friend Mr. Guest who happens to be an expert in handwriting. They sit and look at Mr. Hyde's letter. Now Mr. Utterson has another letter from Dr. Jekyll who is an invitation. So Mr. Guest asks Mr. Utterson if he could see that letter and use it as a comparison with Mr. Hyde's letter. In comparing the two letters he realizes that they are the same and that the only difference between the two letters is the slant.
