The two of them suspect Morland of ordering the hit in the diner, but the evidence is pointed in a different direction after the suspect confesses to another murder for hire by the same person two weeks earlier. An online survey created by this victim in order to change the future perspective on sentencing is found to be connected to another simultaneous crime in Geneva and a lab assistant selling information on the ones coming up as psychopaths to what she thought was the CIA.

423	 	The Invisible Hand 	1 May, 2016 	Robert Doherty & Jason Tracey 	Guy Ferland 	
423	 	As Sherlock is reviewing known evidence, which leads him to the conclusion that, instead of the imprisoned Moriarty, someone else is wielding the scepter in her organization, Morland's office is bombed by the Russian hitman. This leads Sherlock to an obscure professor, Joshua Vikner (Tony Curran). Not only is he the caretaker of Moriarty's organization, he's also the father to her daughter. New evidence on the hitman surfaces, after which an angry Morland appears at the brownstone trying unsuccessfully to coerce Sherlock into giving up the name of the caretaker. The Russian hitman is arrested, but doesn't share any useful information. Sherlock notices corrosion on his belt and a distinct smell, illuminating which type of propellant was used in the bombing. This points the team to the upstate theft of a pesticide barrel and a missing person. Meanwhile, Vikner summons Sherlock to gauge interest in a possible truce with Morland. As the team prepares for an interview with the DA, the prisoner is assassinated in a murder-suicide by a rookie cop who turns out to be one of the psychopaths flagged in the DANTE survey. When Sherlock and Joan return home, they come face to face with a bomb identical to the first one.

424	 	A Difference in Kind 	8 May, 2016 	Jason Tracey & Robert Doherty 	John Polson 	
424	 	Sherlock quickly disarms the bomb and deduces that it was not Vikner, but another member of his group who wants to dethrone him by killing them, thus breaking Moriarty's rule of not harming him and Joan. The two of them find out with help from Morland that the bomber is connected to an Iranian diplomat in the organization, Hashemi, who is bent on deposing Vikner as leader. They meet with her only to realize the enormity of the organization and to learn the reason why Morland was targeted by Vikner. Some in the organization, like Hashemi, wanted Morland as the new leader until Vikner played his hand. Sherlock, Joan, and Morland work together to frame Vikner for a federal crime, only to find out that he was tipped off by a contact inside the FBI and is in the wind. Morland, in an attempt to protect his son, then contacts Vikner, who thinks he's going to be able to kill off Morland. Morland, however, has allied with Hashemi, so Vikner is killed instead by her men. Morland meets Sherlock on the brownstone's rooftop, telling him that he has taken over leadership of the organization with the aim of dismantling the network from within and explaining to him that it was the only way to guarantee he would not lose his son. He also promises that the group won't have a presence in New York and prepares to return to London.
