What I meant was why was the worker's car left there overnight? Has that been established?
There is nowhere it says Jeremy planned to keep the fortune to himself. There was that issue of the ring, Ann wanted it, but Jeremy said it was to stay with the body of June. Now that is seriously ungreedy IMO.
Ann mentions this friendship of her's with a police person. There are many odd details in her statements.
Have you gone through them opening them up one at a time? Is there a better way to see these statements?
I can hear that you're itching to find something previously undiscovered, but I don't think there's anything sinister about the worker's car being there overnight. After a long day, if said worker had ended it being nearer home with a farm implement, he'd have used it to get back in the morning. It occurs to me that a mass murderer wouldn't leave his vehicle at the scene of crime.
It probably wasn't stated in words of one syllable what were Jeremy's intentions, but again, actions speak louder than words, and none of his actions suggest he was someone who's life was in farming (the terms of Nevill's will were that Jeremy had to be working the farm [in a way which satisfied the Trust?] before he could inherit, so, having seen the Will, such may have been the reason for him having recently 'knuckled under')
I don't believe there have been anything altruistic about Jeremy wanting June's jewellery incinerated (in fact, I believe it wasn't. I think the undertaker returned it to the family solicitor) and I'm going to throw in a really wild theory here!!!! Jeremy MAY have been superstitious. When a close supporter suggested employing a medium, Jeremy was furious -or was he scared?- MIGHT he have thought the owner's history could be discerned from holding their jewellery?
So Ann had a friend in the police force? And she put the friendship to good use? Under the circumstances, who of us wouldn't? If you picked it up, she clearly wasn't trying to hide it. She probably did voice her concerns and her friend may very well have suggested she kept a notebook with her to make sure she remembered everything. If she'd learned shorthand whilst doing her typing course, it would have been easy.
I have read her statements, but not recently.
