No fiddling required Lookout and NO TORCH either!
Supporters appear to infer that, as the 'deed' suggested by guilters, was a spur of the moment decision on Jeremy's part, it couldn't have happened because too many obstacles would have prevented it. I'm inclined to think it was something carried out, from a start point of fantasy, to a place where it all came together like a perfect storm, with (almost) military precision.He'd certainly have been dreaming of circumstances occurring which would allow for it to come together.
It's not unlikely that the 'fantasy' became a 'necessity' during Sheila's last spell in hospital. It was probably hard enough to swallow that her freedom/family was being funded by Nevill, but exorbitant private hospital fees, too? If he envisaged years of this, he'd not only see his inheritance dwindle, he'd see himself as having to work to pay for it. There may never be an end to it.......................and then, miraculously, it all started to fall into place. His fantasy may have needed no more adjustment than a bit of tweaking to make it happen.
