Twenty something Sherlock Holmes and Jame Moriarty hatch a plan to start a war and profit, only to be undone by a secret government agency headed by Mycroft Holmes.

1892 Mycroft Holmes heads a mission to stop a plan to undermine England position in Afghanistan not knowing the villains are a young Sherlock and Moriarty.

Agree with Nir Shelter. ?I can only see this as marketable if framed as a redemption narrative; how a young Sherlock starts off on the wrong track, abuses his powers of observation and deduction, finally gets on the right track, on the right side of the law.

Or as a sci-fi story of a Sherlock character played out in two parallel worlds, one in which he's a good guy, the other in which he's the opposite. ?Inevitably, the two characters's lives must converge and collide over the same dramatic issue. ?Which one will survive?
