Dark!Sherlock has his pawns just how he wants them. His unwitting protege and future lover, John. His favourite toy and his brother's obsession, Lestrade. His desperate for attention pet Detective Inspector, Dimmock. He has his faithful network of homeless and petty criminals to carry out the tasks that need doing to perpetrate his facade. His brother owns the government through thier secrets, having taken over Appledore in 2005.
The only person who can reveal Sherlock's true nature as a depraved serial killer perpetrating the very crimes he solves is Richard Brook, a small-time actor he went to school with, whom he hires to be a 'criminal mastermind' he can thwart for the public, planning from the start for his spectacular execution.

TLDR: Richard Brook was right.
