She was in recovery so let's hear no more bullshit lookout. Sheila was looking forward to a new beginning with her family, a new beginning which was a very big threat to Jeremy Bamber. All of a sudden he was about to lose a huge chunk of his inheritance so his hand was very much forced. What better opportunity did he have to get rid of them all at once? ...coincidence? Hardly!
Remember the pills he was going to use on them? How he was going to burn down the house but thought better of it when he realised that all those antiques would also burn. If anyone had a mental illness I fear you can lay that particular affliction at the feet of Jeremy Bamber.
Isn't it interesting, the different ways in which we all see Sheila. I wonder who she was really.
I don't believe she was looking forward to a happy life with the family. Not the English one, anyway. I think, when her biological mother left she took with her all Sheila's hopes of what might have been and she may have been left with what was. Certainly, she seems to have accepted religion but I suspect more to please June than herself. I get the feeling that she may have had to work very hard at pleasing June and may even have tried to persuade the boys to do the same.
I can't go along with Jeremy having a mental illness. I'll settle for personality disorder, though.
