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? As hard as MI6 has worked to keep Moriarty's presence in London a secret, rumors of the Lord of Crime's return have spread throughout the city--except it's not William Moriarty they're talking about. Someone out there is plotting to use the Lord of Crime's reputation to their own advantage, but who could it be? With a highly addictive and deadly drug sweeping its way across London, this new player could very well make an already volatile situation more explosive than ever.
