[Ann] therefore wouldn't know anything about Sheila's recent co-ordination - something she talked about.
Couldn't agree more. Ann's presumed expertise on Sheila's condition probably derived from an unfortunate combination of ignorance and necessity.
I don’t accept the argument that she was all quiet and lifeless on the night of the killings
Couldn't agree more. I see events in the farmhouse as comprising of an abject horror and sheer panic on the part of a startled, disorientated Nevill and June.
The quiet, dozy Sheila, unable to not spill beans, is as corny an image as.. 'the silencer made the rifle too long for Sheila to have committed suicide'... etc.
It's just prosecution sound-bites for the uninitiated.
