Ever since Lucy Beale's lifeless body was found on Walford Common in EastEnders, we've been suspicious of every single character.
But one person's whose name has popped up more than others is that of Lauren Branning, played by Jacqueline Jossa.
Many people believe that - as the duo were fond of wearing matching suits, not to mention shared a job - little Lucy's death was a case of mistaken identity… and that LAUREN was the intended victim.
But what does Jacqueline think about that theory?
Chatting to the Daily Star, Jacqueline teased: "No one has a clue what's going on.
"He [executive producer Dominic Treadwell-Collins] might change it up. They will probably put it to bed and then another piece of evidence come up and it’ll start up again."
Meanwhile Lucy's former lover Max Branning will soon be seen getting closer to the office investigating her death - will he find enough evidence to clear Jake Stone's name?
