A Scandal in the British Empire Act 3

Synopsis

Adler meets Albert with his face hidden to hand over the documents, but Sherlock appears, having deduced only the Lord of Crime could keep Adler safe from the government and so offers the documents if he keeps her alive. Albert agrees and gives Sherlock an envelope with the name James Moriaty inside as an insurance policy if Sherlock ever suspects Adler is dead. Albert takes Adler to William where she realizes the Lord of Crime is an organization. Mycroft meets with Albert, who admits he is fascinated that Maximilien Robespierre was secretly a British agent. Due to the scandalous nature of the documents, Mycroft is forced to let William continue reforming society. William suspects Mycroft's motives and Mycroft admits that he is also avoiding personal humiliation as Robespierre's real name was actually Sherrinford Holmes, his ancestor. Adler is later found dead, but Holmes had already been sent a sign by Adler and thus knows she had faked her death, so he burns the envelope without looking at the name inside. It is shown that under William's guidance, Adler is living as a man named James Bonde. (Source: Wikipedia)
