Adam earlier raised the prospect of the jury having an "Adam" to ask what he considers probing questions, although I am sure that the hypothetical jurors in Adams scenario would agree that Adams questions are in fact far from probing but rather display a disregard for inconvenient facts and that he ignores the answers anyway.
If only EP had an "Adam" they would have "solved" these mysteries much quicker than they did.

If I was on the jury I would discuss -
The 19 reasons/facts why Neville would not make the 'mysterious' call to Jeremy.
How it benefits the accused to ring up the police. See page one.
The strange goings on in the accused cottage when the phone rang. See earlier post.
The vast amount of 'curious coincidences' in the case. See my thread.
I would give them my scenario of how the accused did it. Which matches the body locations & bullet allocation.
I would invite a Sheila scenario.
If no one could give me a Sheila scenario I would ask 'what was Sheila doing when Neville made his 'mysterious' phone call ?
