In dramatic scenes which air next week, Eddie decides to make a fresh start by bringing his antiques business to Walford when he finds new work premises in the area.
However, the charmer's dreams go up in smoke when one resident decides to set all of his stock alight. Despite his sons Tyler and Anthony (Tony Discipline and Matt Lapinskas) trying to fight the blaze, Eddie is left with nothing.
In the aftermath of the mystery attack, Eddie decides that his estranged son Michael (Steve John Shepherd) must have been responsible due to their long-running feud.
"Tyler and Anthony try to help but nothing can be done - everything is destroyed," an Albert Square source told The Sun. "Eddie looks on devastated, his whole life appears to have gone up in flames.
"He is determined he knows who is to blame - but is he right?"
David Essex joined the cast of EastEnders in the role of Eddie earlier this year.
