When you watch Elementary Season 4 Episode 24 online, Sherlock and Joan come home to the brownstone and face down a beeping bomb. Though Sherlock is able to disarm the bomb, it is not the only threat facing them. Moriarty's extensive criminal network is just as dangerous as it ever was, and far more vast and deadly than Sherlock ever realized. It is time to face the treat head-on. To this end, Sherlock's father Morland offers all his extensive power, money, influence, and abilities. And yet, despite this, it is entirely possible that they are both actually in over their heads, and daylight is fading fast. Joshua Vikner is just half the puzzle, the man who came out on top in a power struggle to take control of Moriarty's organization. There is another figure, someone else who had been proposed as a replacement for the notorious criminal mastermind, someone Vikner wouldn't stand for being the top dog in the criminal network. An outsider, with a dark and ruthless reputation. Who is the person Vikner is at war with over Moriarty's organization? Can Sherlock, Joan and Morland stop this war?
