"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? Just as everything appears to be going his way, Sherlock finds himself arrested for a murder he didn’t commit in a plot orchestrated by none other than Moriarty! He soon escapes police custody and sets out to clear his name. The victim, Count Drebber, wrote Sherlock’s name in blood before he died, but why? Will Sherlock be able to solve this puzzle and save himself?"
