Patrick Blake (Jeremy Sheffield) met his maker when his twisted granddaughter Nico Blake smothered him with a pillow.
However Maxine Minniver (Nikki Sanderson) wrongly believed that he had committed suicide - and planted evidence around the house to frame her for his murder.
So, to save her skin, she and Darren Osborne (Ashley Taylor-Dawson) embarked on a shock cover-up, hiding his body in a wall.
And now it seems as if their big secret has finally been exposed.
Persephone Swales-Dawson, who plays Nico, explained in a new Hollyoaks teaser video that her character WILL finally learn the truth about her grandfather’s body.
She explained in the video: “Nico’s going to find out that Patrick’s body is hidden in the wall.
“Darren and Maxine’s secret is going to become Nico’s secret too… but what she’s gonna do with this inside information?”
And that’s where things get pretty spooky - yup, Patrick’s voice can be heard floating out from deep inside the wall.
Check it out:
It’s just like Nico to put the frights into us - but could there be more to this spoiler video?
Could Patrick still be alive somehow?
After all, Maxine has heard Patrick’s voice floating out over the baby monitor at home.
And we’ve already been warned that this wouldn’t be the last time we’d hear from him, either.
Is Maxine being haunted by her past? Is she being targeted by someone - presumably Nico - in a cruel series of pranks?
Or is Patrick, somehow, still alive?
