My take on what an episode featuring a third Holmes brother (played by Tom Hiddleston) could look like. The long lost and presumed dead Sherrinford Holmes surfaces and enlists the help of Sherlock and Watson to stop an attack on London by an extremist group. But after working undercover for several years, which side is he actually on?
