Sherlock Holmes and a Case of Angles [INCOMPLETE]

Sherlock is dead, and to John the world has ended. It's been 18 months and John is still not over that fall that broke his heart. He tries not to show it to everyone, even himself, that when Sherlock died a part of him died too. Finally, when John thinks he has a handle on his sanity, supposedly dead people start showing up on his doorstep... will he handle reality or will it be too much?
