The untold story of Sherlock Holmes’ greatest rival, Moriarty!

Before he was Sherlock’s rival, Moriarty fought against the unfair class caste system in London by making sure corrupt nobility got their comeuppance. But even the most well-intentioned plans can spin out of control—will Moriarty’s dream of a more just and equal world turn him into a hero…or a monster?

Sherlock’s murder of Milverton reveals to the entire British Empire the shocking truth that William James Moriarty is the Lord of Crime! With both noble and commoner cursing his name, William sets his ultimate plan in motion and starts purging influential figures. Realising that William means to shoulder all the blame himself, Louis and the others must decide what to do.
