In a report from TV Guide, showrunner Rob Daherty confirms that fans of the modern-day Sherlock Holmes will experience a confrontation between Sherlock and his nemesis, Moriarty.
However, the EP weighed-in that they will intend to create their own version of Moriarty and not just build a character based from the original novels. Below is his quoted statement ---
The intention would be constructing a nemesis that is appropriate to our Sherlock and not necessarily someone from other books, or movies, or shows. We want to build around our guy. If you look back at the original Moriarty, the original motivation was money and profit. He wasn't a comic book super villain. He wasn't doing bad just to do bad. There was a real and relatable motive. So in that respect, I think we will be able to ground our version and make him feel like he's a part of our world and our show.
