Who killed Lucy Beale? It's been the question all EastEnders' fans have been puzzling over since last April, when the 21-year-old daughter of Ian Beale was found dead on Walford Common.
Since then, there have been theories upon theories of what could have happened to the girl - but nothing will be revealed until next week, when the live episodes to celebrate the soap's 30th anniversary FINALLY air.
But that hasn't stopped a dedicated crack team at heat from doing our own investigations. Literally - we've done no other work for MONTHS. So we thought we'd make this video for y'all to show you how our undercover op has been going.
You can also WIN the real-life Albert Square sign, which has been autographed by loads of 'Enders actors, by playing our Who-Though? game below.
What do you think - do you agree with our theory, or have you got your own one?
