The popular detective series, 'Sherlock' has recently wrapped up its season 4 and the fans are wondering whether season 5 will happen or not. However, writer of the show, Mark Gatiss, hinted that the detective thriller may have ended after all.

Gatiss, as cited by The Sun, when appeared at WhatsOnStage Awards hinted that the Season 4 might be the last as the lead actors of the show Benedict Cumberbatch (Sherlock) as well as Martin Freeman (Dr. Watson), are very busy with their individual schedules and they may not have time to film for "Sherlock."

"And obviously we left it in a very happy place... if that's the end I'd be very happy where we left it," Gatiss added giving the fans the hint that the show may get axed eventually.

Moreover, both the actors of the show have set a foot in Hollywood, so it can be speculated that both of them will remain quite busy and the popular duo cannot be cast together as Sherlock and Watson anymore.

Adding to it, both Freeman and Cumberbatch have both joined the Marvel Cinematic Universe and it is keeping the actors undoubtedly busy. Gatiss also explained that it is being very difficult to align the dates of the actors with the production schedule.

Meanwhile, the co-creator of the show, Steven Moffat hinted in a recent BBC Q&A that if they had to end the show, Season 4 would be it. Moffat further added that ending it in any other season would leave too many cliff-hangers.

However, the "Dr. Strange" actor expressed his interest in playing the popular Baker Street detective for as long as the show is on and that he would "never say never" to reprising his role, but the actor also added that the detective series felt "like the end of an era."
