The Second Closest Sun

Sherlock's life after the fall. Excerpt: "'I'm mad,' he tells John one night, a glass of whiskey in one hand, his head in the other. 'I'm mad and delusional and worst of all, I'm illogical. You're not here, John,' he whispers, but it's a tired argument and the conviction is absent from his tone. 'Or maybe you are. I don't know anymore, and that is what frightens me.'"
