I read in inside soap magazine that in the next two weeks that the killer may strike .....come on that would take it to five victim getting silly I know But my money's on Dylan getting murdered

It was already confirmed after Phoebe's death that there will be another murder this summer. It looks like Dylan will get hurt in the upcoming car crash, but he could fall victim to the killer if he doesn't die outright in the crash. Unless the next death is the end of the storyline, there should be at least one or two more afterwards, so the killer could have as many as 6-8 victims before they're through

How many previously healthy young-to-middle-aged people from the same small social circle, being treated by the same medical staff, can suddenly die of a heart attack in that hospital before anyone notices?

They were written off as heart failure from serious injuries (or in Phoebe's case from her recent brain surgery, plus "conveniently" a vital check hadn't been done.) Mariam's death was attributed to her alcoholism, and S'Avage got Lindsey to sign off a report excusing Diane's heart attack to cover the fact that he'd told Tegan to administer drugs that she wasn't qualified to give

It does seem ridiculous doesn't it. Surely the Au Topsys would show higher levels of Potassium and that would ring alarm bells?

It's a pointless storyline. As far as stupid storylines go, this has to be the worst one ever in my opinion. But then again, logic is irrelevant when it comes to soaps. Especially Hollyoaks.

I want the mysterious person to murder Theresa. That would be better than murdering poor Dylan.
