The big TV cliffhanger of 2014 was... How did Sherlock survive The Reichenbach Fall? It's a massive spoiler but... Well, he didn't die (you probably worked that out already). Exactly how Benedict Cumberbatch's character cheated certain death by plunging from a London rooftop will be something you'll have to find out for yourself. Unlike the super sleuth, all you have to do is hit play and relax as season three unfolds, with the usual raft of in-jokes and nods to previous work by Arthur Conan Doyle, including The Adventure of the Empty House of Sherlock and The Sigh of the Four. Test your fan theories with the three episodes which precede the 2016 special, The Abominable Bride, as Sherlock returns to Netflix from January 12th.
