“Sherlock” could be coming to an end after its fourth season, so says its star.

In a recent interview with GQ UK, Benedict Cumberbatch, who plays the quick-witted detective Sherlock Holmes, said the series may have run its course.

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

Cumberbatch added, however, that the idea of never playing the character again would be “galling.”

The BBC One series has been on air since 2010 and has taken several gap years throughout the series. Most recently, the show aired a special titled “The Abominable Bride” on Jan. 1 and production for the upcoming Season 4 just wrapped in August.

“Sherlock” has been nominated for 34 Primetime Emmy Awards and has won seven of the nominations, including outstanding made for television movie and outstanding casting for a limited series, movie, or special in 2014.

Season 4 is set to premiere early next year.
