I agree entirely that Sheila was no saint. In fact I think she may have been all you have said of her, but I think you'll agree that she'd have had cannabis coming out of her ears had she run up a debt that size. She'd admitted to doing coke, only socially. IF there had been a drugs debt, I'm far more inclined to believe it would have been £4000 as opposed to £40,000 and even if it was, it doesn't mean she slaughtered her family.
I agree Jane, it doesn't mean she killed anyone. Maybe I am cynical but in my experience anyone who admits doing coke 'only socially'
Isn't necessarily telling the truth. One side effect of taking drugs on a regular basis is an inability to admit it even to yourself never mind anyone else.
It was just an observation that where drugs are involved often things are not as they may seem and we should maybe be aware of this, who ever is taking them.
IMO, unless the drugs have a connection with the killings I would think it's irrelevant and Sheila's way of life is not particularly our business except it may explain the worry and been a financial drain on June and Neville. I believe she was a dreadful worry to them if not the only one, whatever their mistakes they certainly paid dearly for making them.
