Line of Duty fans fear season 6 finale will be last ever episode as H is unmasked and there’s no sign of season 7

LINE of Duty fans fear the season six finale will be the last ever episode as H is unmasked and there’s no sign of season seven.

The BBC crime drama added an extra, seventh episode to its sixth series, and Sunday’s penultimate show dropped some huge bombshells, paving the way for a stunning climax.

Fans hope this will include the eventual unveiling of ‘H’, but equally, they are worried that unmasking the villain will mean the end of Line of Duty altogether.

Their fears are also heightened by the fact that a seventh series has yet to be confirmed by the BBC or Line of Duty creator, Jed Mercurio.

After the BBC released an action-packed trailer for this Sunday’s finale, viewers took to Twitter to discuss the show’s future.

One wrote: “This is going to be the last ever episode, isn’t it?”

Another added: “I don’t think I could cope if it’s the last one ever! Seems to definitive.”

A third tweeted: “If we uncover the identity of the 4th man…does that mean…this is the final series…. (chokes up)…like the last…ever?”

BBC One’s Twitter account had captioned the new trailer: “Every investigation has led to this…”

The letters then all disappeared apart from ‘H’, meanwhile, the footage showed Supt Ted Hastings (Adrian Dunbar) say: “‘All of these suspicious deaths were orchestrated by one officer in particular – H, the fourth man.”

Discussing the show’s future, Jed told Radio Times earlier this year: “‘We don’t know. Since probably season four, we’ve been talking to the BBC about the realistic longevity of the series.

“It’s an ongoing discussion is all I can say. A lot of it depends on the key
creatives – me and the main actors – finding new stories to tell within that universe.

“We’re in a situation where it’s not entirely clear that there will be a seventh series. We would hope there could be.”

Line of Duty continues on Sunday, May 2 at 9pm on BBC One.
