Eastenders is BACK! Murder mystery! Whodunnit?
Nick Cotton. His death and funeral was an elaborate scam in the hope it would send Dot to an early grave, as he'd found out that the back room of the Mr Popadopolopodopoloposes laundromat was actually a small home movie studio where she starred in hard core porn movies, and Dot was mega-rich. Lucy had also found this out, as Dot's co-star was actually her father, Ian Beale, so Lucy had to be eradicated too.
Who cares?
