informal letter

Dear Utterson:
                       I´m writing this letter to tell you the truth. I´m the inocent one, I´m very unhappy, to tell you that Dr Jekyll has lied to you telling you the oposite about the real story.
   I´m writing you this ´cause Dr Jekyll has created me if he has prevented himself from drinking that potion i wouldn´t exist.
   So i want to send this letter to the judicial Court so the can know the truth and arrest Dr. Jekyll so he can be miserable for ever...
                                         THANKS MR HIDE.
ps: if you don´t send this letter to the Judicial Court in a week, something horrible will happen to you and your family.
