Emmerdale actor Mark Charnock has confirmed that the huge Graham Foster murder twist will air at the end of tonight's action-packed episodes.
His character Marlon Dingle is one of the many suspects in the frame for Graham's grisly murder.
Appearing on Good Morning Britain today, Mark said that he couldn't give much away but teased what viewers could expect to come tonight.
"This red mist has set into him [and he] feels helpless and he's been prodded and prodded," Mark explained.
He added: "Tonight is the big reveal... there's a big reveal at the end of the episode."
Probed on whether he had almost accidentally revealed the killer to anyone, Mark said that he hadn't.
"No, I've been quite good," he said. "I've stayed away from wine for six weeks!"
On Monday we saw Graham seemingly dead amongst a pile of leaves, while Tuesday revealed he was whacked over the head with a pole or bat.
But to add confusion to the tale, Wednesday's tense episode saw the character seemingly thrown or pushed off a bridge or rockery.
So who killed him? Is it Marlon?
*Emmerdale airs tonight at 7pm and 8pm on ITV
