Susan, Back to the scenario of the burn marks on Nevill's back.
I was always, as I am sure most readers were, of the view, that the said burn marks were in a horizontal line.
Was it not NGB, who broached the alternative, that the marks may well have been in a vertical line.
If this were in fact the case, then the top burn mark, if made when Nevill's head was lolling down, then when his head was brought into the erect position, the circular burn mark would become an elLIPtical shape, as shewn in the crime scene photograph. I.e. the mark would have taken up a different shape, owing to the folding of the skin, at the nape of his neck.
I trust SSusan, you will appreciate this, as they say in Pleshey -'It is surely grist to the Mill!!!!! XXXX
