EastEnders boss Dominic Treadwell-Collins is reportedly desperate to keep the mystery levels at an all-time high with the Lucy Beale murder plot - so much so that he's reportedly set to film three different endings to the Albert Square whodunnit.
And even the cast are set to remain in the dark, with plans to issue "fake scripts" to all those not directly involved in the story.
Sources told The Mirror: "Dom’s not taking any risks.
"He’s had lengthy discussions with the three other producers. Only the four of them know who’s responsible for Lucy’s killing."
EASTENDERS: LUCY BEALE'S MURDERER 'ACTUALLY TRYING TO KILL LAUREN BRANNING'
Dominic previously revealed to The Metro, however, that the identity of the killer would not be that surprising to viewers, as he wants the story to feel genuine.
He said: "When they are revealed, we don’t want everyone to go 'Oh, I never guessed that'.
"We want everyone to go 'Oh that makes sense, oh my God, that’s upsetting.'"
