— Sebastian Moran to Holmes, "M.".

Sebastian Moran is an assassin who worked for Moriarty.



Sebastian Moran is an ex-Royal Marine turned assassin for hire. He served a prison sentence of six months at Brixton Prison for beating up a Manchester United fan in 2011. He is hired by Moriarty to kill seemingly random people and killed 37 before being caught. He receives these names via coded text messages. He kills by hanging his victims upside down on a tripod, cutting their throats, and then dumping their bodies in the ocean. Moran is a huge fan of Arsenal (an English football team).

Season One

Moran first starts killing in New York City after Sherlock Holmes moved there. He leaves a cutout-letter note in Holmes' home under the alias of M, not knowing Holmes has security cameras in his house, and discovers his identity. Holmes then sets out to find him to torture and murder him. Holmes captures Moran just as he is about to make his next kill. Holmes believes Moran killed his ex-girlfriend Irene Adler (since the scene of her faked death had the same M.O.) and brings him to one of his father's properties to interrogate him. Moran resists Holmes' intimidation and beatings, and willingly reveals he didn't kill Irene, as he was in prison at the time of her murder. Moran suspects his employer, Moriarty, was the one who killed Irene Adler. Moran realizes he has been set up by Moriarty and vows to cooperate with Holmes as revenge. Holmes brings him to the 11th Precinct and Moran denies that Sherlock kidnapped him. ("M.")

S01E12-Moran at 11th precinct
I've led a charmed life.
Moran, now in prison, informs Holmes of a murder ordered by Moriarty, staged to look like a heart attack. Holmes later returns to have Moran solve a coded message from Moriarty. Moran lies and tells Holmes that he doesn't understand the message. Holmes later solves the code, and it is revealed that the message was a threat to Moran telling him to kill himself, or his sister would die. Moran is then seen committing suicide by slamming his head repeatedly into the wall of his prison cell. Gregson informs Holmes that Moran isn't expected to survive the night. ("A Landmark Story")
