Following the murder of Lucy Beale (Hetti Bywater) in EastEnders on Friday, April 18, the BBC has released a new whodunit 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."
