I'll accept!

"Oye, hey!" Destiny runs after Sherlock and prices the door open. Her voice turned soft. "Don't blame yourself so much. Human life is like this, full of sorrow. What has happened is in the past. If you don't focus on the present, more people may die. Don't hurt yourself with the past! Do it for me! Do it for Moriarty's would be victims!" She paused. "May I come in? I have more things to say."

(It's Oi, not Oye. Oye is 'hears' in Spanish.)
"Sure. Go ahead." he sighed, letting you in.
The flat of 221b was cluttered. You gaze around the room, your eyes lingering on certain oddities. The decapitated head on the kitchen table. The knife in the mantle. The human skull. The stacks off alarmingly odd books such as the 'Stray Pet Cookbook by Alfred Bligh.' For some odd reason, the room had a very homely feel, even with these unique objects.
A blond man sat on the couch, reading Homer's Iliad, his eyes scanning the pages of the book.
Sherlock cleared his throat. "John, we have a visitor." he said in his deep, monotone voice.
John looked up from his (exceedingly dull) book.
"Client?" John asked.
"Neighbor." Sherlock informed him. He waved at you carelessly. "Destiny Lupin of 221c Baker Street. A man was murdered in her house. Moriarty's back."

"Ahem." Destiny coughed and leaned agaist the door frame. "I have some thoughts about Moriarty. First, the murderer of the dead guy in my house is not Moriarty. Second of all, Moriarty is planning something big. How do I know? I simply take a guess with my knowledge of criminal psychology. People commit crimes for many reasons. Love, money, whatever. However, Moriarty is different. He sees crime as a game of Life or Death. He does it for fun. And he sees you, Sherlock, as his opponent, as he believes you are the only one on his level of intelligence. Now, back to the crime. It was obviously not Moriarty. His pride would get the best of him if he had to crawl through the ventilation system. So it is safe to say, one of his goons did it, if it is indeed Moriarty behind this all. Next: he's planning something big. Why would he send the note if he just wanted a showdown with you? Why bother to leave a corpse in MY room? He is taking advantage of your psychological scars of that girl you mentioned earlier. He left it in my flat because it will remind you. And so he predicts: what will Holmes do under stress? Of course, he will try to protect the girl. He's probably set up traps for us outside, and his goons will be shadowing us. I can assure you. However, since there is nothing we can do about the corpse in my room at this time, we should go to the police, even if it's what Moriarty suspects we will do. I have an idea of what he wants to do, so let's go along with his expectations for now." Destiny suddenly noticed Watson standing behind Sherlock. "Oh, hi! I'm Destiny Lupin, a mature magician/thief/detective. Nice to meet you." She offered him a rose.

"First," Destiny held up a finger. "A few questions. This will definitely help, so please excuse me if it gets too personal." She shifted a little. "Under what circumstances did this girl called 'Evansley' die under? Describe everything that happened to me. I will fill in the blanks in my information with the info you give me, and I will tell you everything I know about the professor."

"Ah. I see. Our stories can be related, Sherlock. I am a distant cousin of Arsene Lupin, the ultimate thief. My father knew Moriarty, you see. He was killed by Moriarty in the end, so yeah. Now. Info on the prof. Calm yourself, Sherlock. A detective who finds someone in order to kill them is no different from a murderer. He probably will replay the entire thing until you crack. You still have heart left, Sherlock. Until you break, Moriarty will most likely repeat this many times until you finally can't stand it, and you break. He will strike then, to finish you once and for all. You must remain strong, Sherlock. Don't give in. We'll catch him for sure this time. I suggest we go outside, I need to observe our surroundings for more information. I have pieces of my puzzle in my hand now, you see. But I am missing a couple. And yes, I do plan to meet Moriarty. I have a couple of questions to ask him myself." Destiny gestured at the door. "John can come, too. He'll be a great help."

(Yas, Sherlock is right handed (I believe))
"Okay. Do you have anyone to introduce me to? Right now we have to act natural, as if on the way to a case or just out for a stroll." Destiny discreetly glanced around. "I will be on the lookout for Moriarty's goons. As of now, you should be careful of what you say and write on your phone. It could be bugged." Destiny grabbed Sherlock and John's hand and pulled them down the street.
