To my mind,Neville wasn't even upstairs at any point. Where were his clothes anyway ?
So you are somehow suggesting my reconstruction is necessarily wrong?
I don't see how.
1. Phone off hook.
2. Sheila with gun on body and neck wounds consistent with self delivery
3. Cartridge cases in found locations.
4. Menstrual blood on knickers in bucket on kitchen floor.
5. Tampon in body, and complement of tampax in lounge.
6. Downward shots to mouth as though shooter on landing and Nevill below on stairs.
7. June shot while clearly asleep.
One of the problems confronting reconstructionists is that people customarily paint with the broad brush, everything is possible, but this is nonsense, one and only one exact sequence occurred.
A reconstruction will make sense of most evidentiary data points, seldom all.
Nevill was most of the way upstairs when turned back by gun fire.
Is this compatible with " never upstairs"? I think it is, but I am interested in what you mean Lookout.
