BBC have finally released the first still from the upcoming fourth series of ‘Sherlock,’ which gives us a first look at Benedict Cumberbatch as the titular sleuth consulting with his new four-legged sidekick. 

Speaking with The Telegraph, Steven Moffat doesn’t know how much longer they can keep the series going:

“I don’t know how long we can keep it going. I’m personally willing but I’m hardly the main draw. I would be moderately surprised if this was the last time we ever made this show. But it absolutely could be…

We do have two film stars in the programme. They haven’t needed to do these jobs for a very long time. They’re coming back because they want to. I’m amazed that we’ve got this far. I thought that once they had become extremely successful, we would only get to do one more series. There’s never going to come a time when we do a longer run, because this is what the series has become. It’s an occasional treat where you get three movies. It’s how it works.”

Moffat went on to say that the shows would not be based on any of Conan Doyle’s detective stories. He said: “There are stories that we are making use of in different ways. We’re using stories that people don’t know so much. Now we are getting into equally good, but far less well known, Conan Doyle stories.”

What do you guys think?
