When the death of Lucy Beale was announced by the BBC back in February, the hot favourite in the press to do her in was best friend Lauren Branning. So how does the actress who plays her feel about the possibility of Lauren turning murderous?
"I'd kind of want it to be me," admits Jacqueline Jossa with a laugh. "But I don't think it is now. So I'm a bit gutted. I wanted to kill someone! But she doesn't really have a reason."
No reason? What about the fact that Lucy has been having clandestine trysts with Lauren's dad, Max? OK, so she hasn't yet found out on screen, but with many secrets swirling about on the BBC1 soap, who knows what the main suspects are up to. So how would Jossa react if Lauren were to have blood on her hands?
"I'd be excited," she says. "But it would depend: would she get caught? Anyway, I've got loads of suspects in mind. I think it could be Abi, Lauren, Peter, Dean, Whitney, even Cindy."
With Lucy set to become the subject of the soap's latest whodunnit during scenes to be shown on Good Friday, it seems that there's a lot of finger pointing going on behind the scenes at EastEnders. At a press conference to launch the soap's Easter episodes, the rest of the cast members involved in next week's emotive episodes prove to be just as eager to air their views.
When asked whether Lucy's twin Peter could be a killer, actor Ben Hardy replies: "I don't think Peter's got enough motive. I don't think it would fit the character, but I'd be excited to play it as an actor. It would be a thrilling challenge. My theory is that it's more than one person. Maybe it was an accident? Or manslaughter? But if I had to pick one person, it would be Abi. There's something sinister there."
Laurie Brett, who plays Jane Beale, would also relish the opportunity to play the guilty party. "I would be just so interested to find out how you would make Jane a killer. I think I'm an outside shot, but who knows?"
Even Adam Woodyatt - when not spending time on screen grieving as bereaved dad Ian - has found time to turn amateur detective: "I've got plausible motives for several members of the cast. But I do keep changing my mind: first I thought it was Lauren, then I thought it was Abi, then I thought it was Max."
The soap's boss Dominic Treadwell-Collins has promised that the mystery will continue through to EastEnders's 30th anniversary in February 2015, so there's plenty of time to hone your own sleuthing skills. But why not tell us below who you suspect to be responsible for Lucy's demise? After all, a killer is definitely walking among the residents of Albert Square...
