She was bleeding Lookout, I think Bamber used her own blood to make it look as though she was holding the bible when she died however, I think he probably realised it looked too staged so he tried to cover up by opening the bible on a different page and placing it over the stain. The police probably closed it and didn't take note of which page it had been opened and assumed it must have been on the stained page. He then placed the gun on her and made sure her arm covered the finger marks. But put them together and bingo!
Where was all the blood ? Considering it was a complete bloodbath in that bedroom considering the bullets that were used there was so little blood to be seen especially from arterial areas of both bodies ?
Well that would be a fine scenario except that one or two officers on entering didn't see the gun on her body but by her side, so did JB suddenly skoot along unseen and replace it on top of her body ? Then add a drop of blood here and there for effect ? Where are his prints ? It would have been all that was needed for an immediate arrest.
JB would have had to have physically pressed Sheila's palm onto the Bible to get such an impression, so did he wash her hand afterwards as she had been clear of any blood on her hands ?
