Sheila wasn't interested in the Bible. It was only her mother.
This refutes David's post which says Sheila read the bible.
Neither of you have provided sources.
In this case I will go by my own judgement, the OS and CT Youtube videos. None of which provide any sources that Sheila read the bible. Therefore I agree with you're post.
However I believe the bible next to Sheila was a plant by Bamber. Rather than June putting it there.
