A Man Who Sees Through Everything

                                    

                                          
Keep in mind, this is one of my many first attempts at writing and completing a crossover fanfiction, so no burns, please. Constructive criticisms only.
I don't own Princess Principal, Moriarty the Patriot, the Sherlock Holmes original stories, or any other adaptations of Sherlock Holmes. I don't own any of its characters, or the image I used as the cover above. The only thing I own is the idea behind this crossover fanfiction.
After delivering a letter to perhaps her most annoying tenant, sent by a young man in the middle of a downpour, Miss Hudson, the landlady and the owner of 221B Baker Street, thought there would be no more surprises for the night.
But that all changed as another one of her tenants returned with a few guests in tow, slamming the door open.
"Miss Hudson!"
"John, what are you... Oh, my God! Is she alright!?" The young woman wanted to reprimand him for the racket but quickly reacted in shock at the sight of a bleeding girl in his arms.
"She's been shot, Miss Hudson. I'll take her up to my room." John said as he and Ange got Chise up the stairs.
A door leading to a room was at the end of the stairs.
It opened, revealing a man in his mid-20s, with dark blue, wavy, shoulder-length hair held up in a ponytail, wearing a white shirt with some buttons undone, and navy-blue trousers.
He's as tall as Professor James Moriarty. Ange could discern his height despite his leaning on the doorway.
He looked... off. Seeing his red eyes and ragged breaths, he's most likely under the effects of... substances.
"Oh, John. Welcome back, and it looks like you had some friends with you." He said between breaths as he turned to walk back into the room.
"Not now, Holmes. This friend of mine needs medical attention immediately." He said before turning to Ange. "Young lady, I'll get her treated in my room. You should wait in there for the time being."
"Thank you, Doctor." Ange thanked him as he headed towards another door to a separate room.
She entered the room the doctor had pointed out, and after she closed the door behind her, she instantly dropped her guise.
Like a flip of a hand, she returned to the cold persona of the spy named Ange le Carre.
As Chise was now under the doctor's care in his room, she took her time to look around at the room she was in.
The room had two windows in front of her, with a lit fireplace to the left of the room. A letter opener was seen on top of the fireplace, stabbing through an envelope.
As her eyes scoured the environment around her, she saw that the red-walled room she was in had many tables and chairs.
A table right next to the left window had a small chemistry set placed on it, right next to a shelf filled with flasks, while the others had several assortments of papers and books.
More books were placed neatly on the shelf right next to the fireplace. Others were stacked on some of the unused chairs in the room, and some of the tables.
The place was a mess.
Out of all the things in the room, one element was drawing her attention the most. It was the largest couch in the room, which was positioned right in front of the fireplace.
But her attention wasn't drawn to the couch itself. Instead, it was directed to a man lying on the couch with his left hand on his head, while holding an open letter with his right, looking right at her. A discarded envelope was lying on the floor right next to him.
