Adam I think if anyone really knew Sheila and her life it was her husband Colin although they were divorced he knew June,Ralph and Jeremy. He did say in the book Sheila hated her Mother I know this is a strong word but I am just repeating Colin Sheila would have talked to him about her feelings she really loved Ralph and her twins and had she shot herself she would have died with her babies. He made some great points one he said Ralph would not have allowed a loaded rifle to be left out he would have put it away mainly because of the boys. Jeremy was at Sheila's flat and Jeremy was telling Colin about the nude photo's he had of Sheila how hurtful and disrespectful was that to a man who had just lost his twins and their Mother. I cannot see what Colin would have to gain by not telling the truth and fabricating things Jeremy sent him some dreadful cruel letters he has put them in the book. From what I am reading Jeremy Bamber had two sides to him. Will keep you up to date.
Maybe that was too difficult for her.
In any case, I find it a very odd spot for Sheila to have died in - her parents“ bedroom. Why would Jeremy pick that place? Why not by the twins, in her own room or in the corridor? To get to that spot where she was found, you would either have to go through the room with the dead bodies of poor Nicholas and Daniel - or, literally, step over the dead and disfigured body of June.
Why would Jeremy risk upsetting her to no end and bring the situation out of control?
Unless he just happened upon her there as Harters claims - but that is not usually discussed.
Further, I have a big problem with the way Jeremy would have had to be positioned to be able to shoot Sheila as it is claimed she was shot.
That whole scene in the bedroom is always what I keep coming back to, and the main reason for my doubts.
