My idea? My 'idea' is that the stain is on the wrong page to have come from the stain on the carpet. That's actually not an idea - it's a FACT. Answer me this - why would they have needed to swap the bible?
For goodness sake-------did I mention stains and carpets ? NO. Your idea was that there'd been ONE Bible !
I say there'd been two, one of which was June's,the well-worn one that she obviously took to church with her notes in it,and one which had been free from creases and turned-up edges.
To EP,a Bible's a Bible whoever it had belonged to so because they hadn't known the background of the family probably decided to use just one.
