Also surely JB would be familiar with June's handwriting since she was a fellow director at OCP.
In one breath the CT want to give the impression of close and loving bonds hence the graveside reading. In the next breath JB is unable to distinguish between the handwriting of his mother and sister.
I can picture in my minds eye the handwriting of all members of my family and could easily distinguish one from the other.
The note is explained in CAL's book. Jeremy mentioned in a letter to her that it was confirmed by Michael Ainsley that the handwriting was June's and it was written in her own words on a piece of card and it read - "Love one another. A determination always to act in the others' best interest, whether we feel good or not, whether we like them or not. It is an act of will, commandment to obey. Be determined to be loving and kind to every person you meet whether you like them or not. Lord Jesus in Thy mercy, teach me to love in Thy names sake, help me to live and speak as a Christian no matter what others might think."
The letter was sent to CAL in May of 2013, as such, the CT must now surely KNOW that the note in the bible was NOT Sheila's suicide note? (Or anyone else's for that matter).
