After going missing for three years, Moran is plotting to assassinate Lord Balmoral, a man who threatens the Franco-British alliance. But when Louis tries to convince Moran that murder isn't the answer, his devotion to William leads to a violent confrontation! Meanwhile, Albert has been imprisoned for the crimes of the Moriarty family and takes it upon himself each night to serve penance for an even greater crime-the one he committed against William as a child.
