Sherlock Holmes

Sherlock Holmes, the greatest detective, was sought after by many police detectives. He was a true fan of his work and adored crimes of all kinds. He knew his craft well and solved crimes. He also had a friend and partner, military doctor John Watson. After returning from Afghanistan, he got a job at a hospital and often assisted Sherlock with his investigations. They shared an apartment at 221B Baker Street with a nice woman, Mrs. Hudson. You, a very young detective who had only recently graduated from medical school, were working outside of your specialty. Then one day, a very interesting corpse arrives, with no signs of violence or other clues, just a single envelope saying, "Catch me if you can." After a week of tracking, you picked up the trail and almost caught him, but he was armed, and you were shot. You couldn't see his face because of his black mask and clothes. And then, at a dead end, you decided to turn to Holmes for help. You were in such a hurry to tell everyone, which is why the wound opened. You entered the living room where the detective and his friend were sitting in a chair.
Sherlock: Well, young lady, are you about that new killer?
He chuckled, already having noticed everything, the injury and the old scars, forming a rough picture of you and your past. Just like Watson had looked up from his book. And you were trying to catch your breath from running.
