You explain it in terms of the murders? She's not talking about the murders, she talks about Colin being a 'womaniser' and asking someone to 'investigate' something but nothing about the deaths of the family. She leaves a phone number and talks VERY WELL of her mother. This is another desparate attempt to pass something off as a suicide letter. The letter in the bible was supposed to be a suicide note, turns out it was written by JUNE and that she wrote lots of these notes. The letters and numbers were supposed to be a suicide note but it's just a garbled mess. Now this ...... laughable. I wonder why the CT didn't bother to send the newspaper copies of these notes?

The letters speak of the psychiatrist looking after her mother and also tells of the psychiatrist giving strength in preparation for when the Sun and Police call. It sounds to me that Sheila was doing the " tidying up " re-arrangeing bodies etc in preparation--------for what ? All are covered in blood apart from herself as she awaits photographers and police.
Final words- "He,SYC,won't let anything happen. Famous last words,eh ?
What you FAIL to understand is that the writer was deranged when writing these notes ( unless you can't tell the difference of course )
Sheila was writing as though God was with her when she'd said " I've come to you because God told me to mummy calm.We are both here with you Bless mummy don't let him see you so hurt.I don't mind him being here while I'm with you ". Sheila speaks of mummy ( Christine ) and mother ( June ).
Sheila also tells " mummy "" that she'll soon be looking at her picture in the paper,but you'll be given a lovely portrait of myself and the twins soon "
