Spoilers!
Now that we've seen how Sherlock faked his death, do we know if Moriarty is really dead? If they are cleaver enough, Moriarty's death could also have been faked due to some kind of behind the scenes angle Sherlock acquired over him.
I just can't believe that they would allow this character to off himself after so brief an appearance. Does anyone know if in the original SH books if Moriarty died? I read many of them, but am not an expert on all things Sherlock Holmes.
