It's not totally clear yet horselady, but it's been narrowed down to: Sadie, Jimmy, Donna, Diane, Danny, that old lady with the wig, oh and maybe the estate agent! (it's been said he looks like Jimmy from behind, so it could be a red herring to make us think the dead body is Jimmy when it's not)
Apparantly Jimmy has been seen about a week or so ago filming so it's been said it's probably not him, but hey! you never know ;o)
I do know Danny's suppose to be coming out of it as he may be going to jail in real-life anyway and of course Patsy Kensit is leaving to go to Holby City, so they are my 2 most likely suspects to be killed off! But then that old lady with the wig has been in it more and more just lately.....
So in conclusion I don't know :o)
