This Dark Thing That Sleeps In Me

Sherlock makes an unfathomable choice at the pool-he decides to give up on his life of detection to join Moriarty in a life of high-stakes crime and entertainment. When he finds himself pitted against the evil team, John finds himself questioning if Sherlock's playing a game or giving in to darkness...and if he's lost the Sherlock he might have been a bit in love with.
