20 Mind-Blowing Facts You Never Knew About Sherlock

10. The Most Viewed Episode Is The Empty Hearse...

How did Sherlock survive the fall? That was a question fans were asking for almost two years in the gap between the second and third series. So it's really only to be expected that the most watched episode of the whole series would be The Empty Hearse (12.72 million viewers), where the complex method by which he was escaped was sorta, kinda, not really explained. The episode gave a couple of solutions, but left enough ambiguity to get the internet speculating, something that all the fan theorising in the episode itself was clearly trying to mock. Naturally the ratings dipped a little for rest of Series 3 (they always do), but nowhere near as dramatically as with other shows; The Sign Of Three and His Last Vow still managed 11.38 viewers apiece.
