Benedict Cumberbatch Teases Episode the Answer to "The Reichanbach Fall"

"Sherlock" Season 3 Episode 1 "The Empty Hearse" as suggested has a reunion in store of the long separated friends and confederates Sherlock and Watson. Along with that, there also lies an answer to the most anticipated questions related to "Sherlock" Season 2 Episode 3 "The Reichenbach Fall."

Fans of the show have been curiously waiting to know how their favorite character Sherlock Holmes survived the deadly jump from St. Bart hospital.

Benedict Cumberbatch the leading light of the BBC's show "Sherlock" has hinted that the fans are in for a "treat."

Episode 1 "The Empty Hearse" will provide the answer to the very question.

"I think you're in for a treat... I was too curious not to ask and figure it out myself, I think I sort of got into the same obsession that the nation did before we did it," said "Sherlock's" star himself Benedict Cumberbatch while talking to Digital Spy.

"My personal preference is being surprised in the moment of watching something rather than knowing ahead of time. But I also understand why everyone's desperate to know because it's frustrating. It's witty and loving and intelligent enough for people to actually really enjoy it," added Benedict Cumberbatch.

What does Martin Freeman has to say about the suspense?

"It's very satisfying... it's Mark Gatiss's script that we're doing and it's rather beautiful, as I would hope and expect. It's great," said Martin Freeman who plays John Watson in the show.

"There were lots and lots of theories and some of them were very good, but the way that we deal with it in this episode I think is really clever and ultimately satisfying. It's difficult because once something is revealed and you've already tried to guess and guess and guess the trick, when it is revealed it's very difficult not to be disappointed. We're not actually dealing with my other job it still has to be grounded in a reality - although it's a very heightened reality," continued Martin Freeman.
