Season 4 of Sherlock has just wrapped filming, much to the long-suffering delight of the shows fans. But in an interview with GQ UK, Benedict Cumberbatch hinted that this season may be the series last.

It might be the end of an era,” said Cumberbatch.

“It feels like the end of an era, to be honest. It goes to a place where it will be pretty hard to follow on immediately. We never say never on the show. I’d love to revisit it, I’d love to keep revisiting it, I stand by that, but in the immediate future we all have things that we want to crack on with and we’ve made something very complete as it is, so I think we’ll just wait and see. The idea of never playing him again is really galling.”

The end of Sherlock would be galling indeed. Yet, what is also galling for fans is the intermittent airing of the shows seasons. The busy schedules of Cumberbatch and co-star Martin Freeman have delayed filming for Sherlock nearly since it’s debut. Devoted watchers have only had The Abominable Bride, a one-episode special, to tide them over until the 4th and probably final season. It aired on January first of this year and was the first Sherlock episode in nearly two years. A final season with loose ends all tied up would allow fans to put a rest to the constant anticipation and wonder of when the next season will air. Season 4 is set to air sometime in 2017. Until then, fans can see Cumberbatch in Dr. Strange which releases on November 4th. Freeman can be seen playing FBI agent Phil Rask in Startup, an original series on Crackle.
