Eight people who almost certainly killed Lucy Beale

In the knowledge that this is a pretty big deal for Eastenders and they really don't want it to be an anticlimax, there's every chance the BBC are going to throw a massive curveball when it comes to unveiling Lucy Beale's murderer. What if it's not one of the 14 characters to whom they claim to have narrowed it down? What if it's someone else? What if it's you? Actually, forget that last one; I got overexcited.
