The Revenge of Moriarty - A Sherlock Fan-Fiction Screenplay

To be very clear, I do not own Sherlock or any of the Sherlock characters. This is a work of fan-fiction.
I actually wrote this a year and a half ago, months before The Abominable Bride premiered, but I've always been too scared to post it. But now, only three days before the premiere of Sherlock Season 4, if I'm ever going to post it, it has to be now, before Season 4 either confirms or contradicts what I have written here.
Basically, Mary has her baby, but Moriarty returns to take his revenge. This story is very angsty, but it gets better towards the end, despite a well-loved character meeting her death. There is some Johnlock and some Sherlolly, so shippers of those ships might have some mixed feelings about this story.
This story has been written as a screenplay.
