Benedict Cumberbatch (Sherlock Holmes), Martin Freeman (Dr. John Watson) and the rest of the gang are back together again and the new "Sherlock" season 4 is slated to drop early in 2016.

As reported by The Mirror, both Benedict and Martin Freeman were seen shooting in the notable Glouscester Cathedral, an insider said, "I don't know the plot but they moved a single bed into the crypt before they started filming.They also brought in some other props to put round the bed. I think they are pretending the crypt is another location and aren't using Gloucester Cathedral as part of the story."

Martin Freeman in his interview with the Telegraph said, "While we play fast and loose with the original stories, we generally follow the trajectory of what Conan Doyle did. So [Watson] gets married, and then Mary dies - so at some point presumably she'll die."

The shows creator Steven Moffat spoke with Entertainment Weekly, saying the production team wants to take the "Sherlock" series somewhere it's never been in previous seasons.

"Of course, it's far too early to say what's coming, but we're reasonably confident that the very next thing to happen to Sherlock and John, is the very last thing you'd expect ... " said Moffat.

According to Moffat, the upcoming season will be "better than season 3, with 'darker' storylines".

"We have a plan to top [Season 3]," teased Moffat. "And I do think our plan is devastating. We've practically reduced our cast to tears telling them the plan ... we're probably more excited that we've ever been about Sherlock."

"It will be challenging place to go. We always start with a re-introduction that builds toward a darker climax - we might just be going darker [from the outset]. We got a very, very good set of ideas." he added.
