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? Adam Whiteley, member of the House of Commons, is willing to put his life on the line to fight for equality for the common people of Great Britain. William Moriarty pegs him as a potential ally and gives Whiteley a powerful bargaining chip he can use against the House of Lords--evidence of their wrongdoings. Faced with threats on his life, Whiteley must decide how to use this information. Will his ideals lead him down the path of an angel...or a devil?!

Rated T+ for older teens. Recommended for ages 16 and up for realistic violence and criminal activity.
