Well done. If you are reading this, you have proved that you can think clearly under pressure. Moriarty believed that by threatening me, he could stop the investigation. He was wrong. I hid the evidence and disappeared on purpose. I needed to be sure that the case could be solved without me. Watson is safe, the police have been informed, and Moriarty’s plan has failed. London is safe — thanks to you. Sherlock Holmes
Mission accomplished!
