Jim Moriarty. The spider. The psychopath. The only man who understands Sherlock Holmes. Jim knows how to play the game but Sherlock seems to be losing. Sheriarty Fanfic So many typos

Jim Moriarty is sure that Sherlock Holmes is in love with him. Moriarty has a plan to use these feelings as an advantage for his plans. But then things start to go horribly wrong.

Chemical impulses. Sentiment, feeling. None of this holds any meaning to Sherlock. He is, after all, an intellectual and not a romantic. Deemed as irrelevant, a distraction, a flaw and a weakness, the consulting detective has always been able to put up a front to block from the distraction and help him with the work. But now, there is another man, someone who has also put up a facade. Someone who is also hiding from view, a woven, intricate mystery. Everything about him is intriguing and fascinating and Sherlock wants to know more. His criminal counterpart, Jim Moriarty, is someone he is willing to learn more about. And perhaps these sentiments weren't as silly as he thought them to be after all..
