We’re told that Moriarty’s visit took place on Christmas Day five years ago. Gone."īut all this raises some interesting questions. Sadly, those recordings were made half a decade ago and, as Sherlock co-creator Steven Moffat confirmed at a screening of the episode, Moriarty's subsequent suicide on the roof of St Bart's Hospital in The Reichenbach Fall was exactly what it seemed. "Tick-tock! Tick-tock!" If someone hasn't already turned that into a gif, I will.

Sherlock Holmes fans will recognise that as a reference straight from the pages of Sir Arthur Conan Doyle's original stories, where Moriarty's brother is said to have had the same occupation, but it was also a bit more literal than that as our own Moriarty had great fun shouting "All aboard!" as each of Eurus's puzzles began, and then transforming himself into an unhinged ticking clock as the seconds counted down towards their deadly denouements. "His brother was a station master, I think he was a bit jealous." "Moriarty recorded lots of stuff for me," Eurus told Sherlock. It was unclear at the time what she wanted Moriarty for but we found out later in the episode that one thing she had asked of him was to record various video messages that she would use years later in the deadly Crystal Maze she had designed for Sherlock to solve. Five minutes unsupervised with Moriarty was all she requested in return for using her superhuman powers of deduction to help Mycroft pinpoint a string of planned terrorist attacks.
