Eastenders fans are sure to have tuned into last night's episode which has been talked about for weeks now.
It concentrated on events in the run-up to Lucy Beale's murder, ensuring there are more than a few suspects in this particular case.
As viewers try to figure out who did it, the BBC has just released a new trailer,There's a Killer Amongst Them.
The show's Executive Producer, Dominic Treadwell-Collins, has said of the murder-mystery: "It's going to run into the 30th anniversary during February next year. But there are some very big curveballs to be thrown at the audience between now and then."
He added: "And in the run-up to Christmas this year, there is a big twist that will make everybody gasp."
It's a long time to wait but this is likely to be an interesting storyline!
