It had audiences gripped all over again, so surely after the success of its second series, there's more of The Missing to come?

Not necessarily. Series writers Harry and Jack Williams had previously insisted that they'd only do a third outing if they could dream up the right story.

Now, the pair have told Digital Spy that it's possible there may not be a third series at all, if they can't come up with a plot that's "absolutely right".

"I think it's possible... there might not be one," Harry said. "There's Godfather I and Godfather II... and third ones are really hard to get right. The second one's hard, but the third one's even harder and you don't want to leave a bad taste in the mouth.

"But we still don't want to say goodbye to Julien (Tcheky Karyo) - both the actor and the character is someone we want in our lives in some form or another. It just may take quite a bit of time before we figure out what that is."

Jack suggested that he and his brother might even turn their attentions to a Julien Baptiste spin-off, rather than another The Missing sequel.

What to Read Next

"Is there a world where Baptiste comes back in his own show and it's not The Missing?" he posed. "We haven't decided at all, but I think if we found the right form to get us excited again, we'd do it.

"We love the world, but the worst thing we could do is rush and say, 'You liked that? Here's some more!' - because guaranteed it would not be good."

The Missing series 2 is released on DVD on December 26. The Series 1 & 2 box-set will also be available on the same date.
