Pamela did know that Sheila was ill,but I don't think that she knew exactly HOW ill she was.As far as I am aware,Pamela does believe that Jeremy is guilty,but whether this is because her late husband convinced her,who knows. However,I have never read or heard of her badmouthing Jeremy.She certainly didn't back up her husbands claim that June had supposedly told her that she had caught Jeremy showing Sheila how to load a gun!
