Who did kill Archie Mitchell?

Stan James are betting 7/2 you can name the killer of Archie Mitchell ahead of Friday's live BBC 1 episode of Eastenders when the identity of the murderer will be revealed to the nation.

Head of PR Charlie McCann: "We haven't seen a penny for our early favourite Stacey but Ben at 7/2, Bradley at 11s and Grant at 16s have all been the subject of support.  Many have a motive. Indeed I never truely forgave him myself for his performances as Matt Taylor in Triangle back in the 80s but I have a plausible alibi for Friday night. But just who did kill Archie Mitchell? We'll soon find out."
