My dear Watson (wrote in the letter): Thank you for your kindness, Mr. moriarty. I am writing these letters, and he is waiting for the final discussion on the existing problems between us. He outlined to me how he got rid of the British police and found our whereabouts. This further confirms my high opinion of his talent. I am very happy when I think that I can get rid of the harm that his existence has caused to society, although I am afraid that it will bring sadness to my friends, especially to you, my dear Watson. However, as I have explained to you, my career has reached a critical juncture, and for me, nothing is more satisfactory than this ending. It is true that if I am completely honest with you, I am fully aware that milligan's letter is a scam. I let you go because I am sure that a series of similar things will follow. Please tell Sheriff Patterson that the evidence he needs to convict the gang is put in a file rack with the letter M and a blue envelope with "moriarty" written on it. When I left England, I had disposed of my property and gave it to my brother Mycroft. Please give my regards to my friend Mrs Watson.

Your loyal Sherlock Holmes.
