A few weeks ago, 'Sherlock' fans were overjoyed to hear that series stars Benedict Cumberbatch and Martin Freeman had already signed on for a fourth season, despite filming on season 3 having only just begun. Even with at least six more episodes confirmed for the future however, 'Sherlock's season 3 premiere will still have some major questions to answer regarding Sherlock Holmes' survival of "The Reichenbach Fall," so what do we learn from the season 3 premiere's title? Get the latest on 'Sherlock' season 3 inside!

No 'Sherlock' fan could have been surprised to see the title character surviving his apparent death at the climax of season 2 finale "The Reichenbach Fall," but the bigger question remains of just how he pulled it off. As filming on series 3 gets underway, series creator and producer (and Mycroft!) Mark Gatiss has revealed the title of season 3's first episode via Twitter, identifying the premiere as "The Empty Hearse."

"The Empty Hearse" no doubt correlates to the classic Sir Arthur Conan Doyle story "The Adventure of the Empty House," in which the character of Sherlock Holmes was similarly revived from his death plummeting from Reichenbach Falls, and introduced to the character of Sebastian Moran. As for how our 'Sherlock' survived his seemingly conclusive death, Gatiss remained mum, but previously teased how Sherlock might ultimately reveal his return to his partner John Watson (Martin Freeman).

 We made a decision right from the get-go that he would not do disguise in the traditional sense. He actually has a line in [series one finale] the Great Game which is ‘The art of disguise is knowing how to hide in plain sight’ and that was because, right from the start, I thought modern day Sherlock Holmes would not put putty noses on, he would basically be standing behind you now and you wouldn’t know he was there. Ben [Cumberbatch] has put on various costumes but it’s more about being invisible.
