Transcript from video:
We arrive, the weather's good, we can see the house, we've got a clear view of the house, although there's no artificial light - we're relying on moonlight; it was a clear summer night [pause] erm, we speak with Jeremy Bamber, who says that potentially there's a [pause] a mad woman in the house with a gun. I already had in the back of my mind I was going to call out the firearms unit, 'cause I wasn't going to go and knock on the front door and risk it being answered by a mad woman with a gun. Erm - also, I didn't want to go close to the building because [pause] if you're seen, then obviously you could become a target yourself, so what,
what I asked Jeremy if he'd mind doing is come with me and Steve Myall, one of the Pcs, on a tour of the perimeter of the farmyard to have a look, see what we could get from the house. As we go round, Steve Myall says "Oh, hang on, stop. I think I saw someone move." And we look up and think 'Where?' He said "That window up there." And he's indicating as we're looking at the back of the building, top right, so first floor on the right-hand side, no light coming out of the building, and I couldn't see anything. We, we look at it for a while, and I said "Are you sure you saw something move?" And he said "Well, I think so." I said "Well, let's move back." We became quite satisfied, after a couple of minutes of just moving ourselves slightly, that we could replicate the same sense of movement, and it wasn't anybody moving, it was just a trick of, literally, a trick of the light.
.....
Because of the fact Sgt Bews said "As we go round" and "we're looking at the back of the building" and gestured left to right anticlockwise.
it can ONLY have been the BOX ROOM window.
A few feet from where Sheila was found dead.
Emphasis on the words "As we", this Emphasises it was at the beginning of the circumvent.
Otherwise would he have said "we had gone round".?
As I say Sgt Bews makes it very much sound that it was at the beginning of the circumvent
Many thanks @reader
