The climax to the drawn-out “who killed Lucy Beale story was set to be broadcast in February as the popular soap celebrated its 30th Anniversary.

The money clearly suggests Walford’s police will be arresting Jay Brown sooner rather than later.”

Jamie Borthwick is the actor tasked with portraying ‘Enders bad boy Jay Brown. Several clues have been laid by scriptwriters; Jay Brown was revealed to have travelled on the same bus as murder victim Lucy Beale (played by Hetti Bywater) on the night she was killed.
