When you watch Elementary Season 4 Episode 10 online, a Russian businessman, his bodyguard, and a valet are violently killed by two Ukrainian hitmen just outside a strip club in New York. The two hitmen make their getaway, but they lose control of their car, which then crashes and kills them both. Sherlock quickly discerns that their vehicle was hacked and enlists help from one of his Irregulars to track down the source of the hack software. There are an abundance of clues and suspects to be had, but despite the Russian's less-than-savory business practices and background, everyone they meet seems to have no motive for actually wanting him dead. Meanwhile, Morland Holmes pays a call on Joan and invites her to dinner, much to her surprise, and asks her to look into something for him. What exactly is Morland up to, and why? Joan is suspicious. Sherlock, on the other hand, is busy trying to solve the death of the Russian oligarch and the two hitmen. Sherlock and Joan, plus Bell and Gregson, seem to be left with far more questions than answers. Find out what happens when you watch Elementary Season 4 Episode 9 online!
