Had the shutter been fully up and the window wide open around 9.30pm then Matt would have noticed. For any prior to 9.30pm abduction to work Matt"s statements must be rubbished.
Tanners sighting is irrelevant imo.
Not sure that I agree with that, if there were a lull in the wind..
The holes in that shutter when looked at from outside are only a very small percentage of the shutter. I worked it out once but have forgotten, but I think they were only about 10% of the shutter.
Thanks to the trees the light outside was very faint, almost certainly not as light as the light shining through from the sitting room ... so it would not be noticeable
The curtains were drawn at that time so altho rather cheap they would take further light.
I am not at all sure that you are right on that one, John
PS, I am aware that there are photos showing the shutter from inside with intense light / sunlight shining thru. This sunlight has the effect of making the holes appear far bigger than they really are. Refraction, halo effect, or just the far brighter light dazzling. Like headlights shining in the eyes make the headlamps look bigger.
It is an optical illusion and the size of the holes should be considered from outside, imo. They are very small. Do we know how high the shutter was opened? I didn't think it was opened very fully.
