Well that's the thing, I had always assumed the blood had been transferred to one of the pages from the floor, but if you look at the way the bible is sort of 'tented' up, with the pages fanned out underneath it, it can't have come from the floor, not on the page on that side. Because it starts on the page furthest from Sheila's arm, it can't of come from the blood you see there either.
Thanks for finding the photo Caroline 
Hi Bridget, never assume....

We don't know what amount of blood there is under the carpet. A photo shoot from the other angle shows a fair amount. Where there is a large pool area of blood, tells me that is where the person was shot, which rings true that it was whilst she was propped up slightly on her right hand side. If you look at her right hand, it appears she may have been holding something, but I thought that might be the rifle barrel....I could be wrong, you would say I am wrong
Maybe one of your experiments would work......Pole anyone?
