When you watch Elementary Season 4 Episode 6 online, a sniper calmly targets pedestrians in New York, killing several and wounding others. It is immediately suspected that he was targeting someone and shooting other people to make it look like an incident of random violence. Morland Holmes offers Sherlock his assistance on the case, making his significant resources available in order to stop the sniper before he can flee the country. Sherlock is understandably suspicious of his father's motivation, but ultimately caves, accepting his father's help. They immediately examine the victims to find the most likely candidate for an assassination, which leads them to an energy company employee working on a huge project with a value in the billions. Could it be that he was killed over this project? It starts to look that way as Sherlock and Morland delve deeper. Joan, meanwhile, doesn't trust Morland or the fact that his heart apparently grew three sizes that day. Will Sherlock and Morland be able to discover the truth about the killings? What else is going on here? There is clearly more than meets the eye in this case, and it's up to them to find out.
