Jennifer Metcalfe has stayed tight-lipped over her shock exit storyline in a new interview about her departure from the soap.
Wednesday's E4 first look episode (November 19) saw the actress's character Mercedes McQueen go out with a bang as she appeared to have been murdered by Freddie Roscoe.
The act itself did not take place on screen, sparking much speculation and intrigue among viewers - but fans did see Mercedes's lifeless body being dragged away before a frantic clean-up operation began at the McQueen house.
Speaking in a Story of Mercedes video released by Hollyoaks, Metcalfe hinted that the exact details of what happened could stay under wraps for a while.
She said: "Mercedes's departure is totally shrouded in mystery. Running up to the week where she exits, she has really annoyed pretty much everyone in the village, so it's 'who's done it?'
"Who has she got involved with? What's gone on off-screen? Is it all as it seems?"
Charlie Clapham, who plays Freddie, has also responded on Twitter to the fan reaction over his character's latest dark behaviour.
The mystery over Mercedes's sinister exit will continue on into Hollyoaks' milestone 4,000th episode, which will air on E4 on Thursday (November 20) and Channel 4 the following evening.
The McQueens are initially oblivious to any foul play, but it's not long before some worrying evidence comes to light and the police launch a murder investigation.
Metcalfe's departure from the role of Mercedes was announced in August following an eight-year run for the character.
