If you read Mrs Ramsey’s ’97 interview and compare it to the house blueprints you will see that Mrs Ramsey was on the phone facing north (towards the spiral staircase) and Mr Ramsey was facing south (towards the phone) with the ransom note between them. So, IF (if, if, if...) this account is true, then no one was blocking anyone’s view. And, for those who think that Mrs Ramsey would not have been able to read the note like this, BPD included, consider that Fernie did a similar thing, only from farther away!He was hunched over the note while she was on the phone with 911. She was not able to see the note from her vantage point.
Btw, the fourth book I read was "The Death of Innocence". So I am endeavoring to be a little open minded here.
Could it be she was recalling what she had written? Trying to get it right? Most of her wording during the call seemed strange to me.
