Emmerdale star Danny Miller has hinted that the 'Who Shot Robert Sugden?' mystery won't rumble on for months.

The actor, who plays Aaron Livesy, appeared on ITV's Good Morning Britain today (September 25) to tease tonight's explosive episodes which see Robert gunned down by a mystery assailant in the village.

Offering an insider's view on the storyline, Miller confirmed that the cast and crew have been aware of the culprit's identity from the start, as it won't take too long before viewers see the big reveal.

The show has taken a different approach to rival soap EastEnders, which kept most of its own team in the dark over Lucy Beale's killer until the last minute this year.

"I think people do it differently. If you want to do it that way, it's fine. If you want to tell people, it's fine. Either way it works," Miller explained.

"I think we know as a cast because it was never supposed to be as long as some of the others have gone on. We knew so that we could play it the way we wanted to play it, which I think is easier because you're not constantly worrying, 'Is it you, is it me?' You know and you just play it the way the script says then."

Emmerdale has previously teased fans by hinting that the big reveal will take place in a very unusual way, but Miller kept tight-lipped about exactly what to expect.

He laughed: "I've got to be dead careful what I say! It's something that hasn't been done in soaps, as far as I'm concerned. It's something that's completely different. I think it's a really clever way of telling it.

"You have to be careful with these whodunits, because there's been so many of them that you've got to make your little mark on it. This particular episode - the reveal - will."

Aaron is among the many suspects in the mystery after his turbulent on-off relationship with Robert over the past year.

"He's the first on the scene," Miller confirmed. "Naturally he's in there with the suspects. Robert's upset so many people in the village, so it could be anybody. Moreso Aaron than anybody else, because he's been his love interest and his dirty secret if you like. I think he's got more reason than anybody!"
