This week marks the 30th anniversary of EastEnders and the show intends to celebrate in style.
One of the big storylines for this week is the big reveal of who killed Lucy Beale, a storyline that has been running since Good Friday, 2014.
Since the murder, clues have played out on-screen with many red herrings and suspects coming in to the fold. Officially there are now 14 suspects left…
They are based on who received PC Emma Summerhayes dying text and are Abi Branning, Ben Mitchell, Cindy Williams, Denise Fox, Ian Beale, Jane Beale, Jay Brown, Lauren Branning and Lee Carter.
Joining the line up are Les Coker, Max Branning, Pam Coker, Peter Beale and Whitney Dean. Although show bosses have never officially ruled out other characters being in the frame.
The BBC have released a video summarising the story so far, including many of the clues that could lead to working out who killed Lucy.
