But Nevill had always calmed her down in the past(without Jeremy's help)and I can't believe the docile,vacant state Sheila was in was compatible with the bashing Nevill received. Far more likely with Sheila in such a compliant state she was led to her death like a lamb to the slaughter whether you believe it was Jeremy or an accomplice as was raised again recently.
I would imagine that Neville tried to contact Jeremy in the earlier stages of the outburst,but was beaten back with further threats. Nevilles' final call was sadly in vain.
Sheila would not have been docile,,,vacant perhaps,because she'd have been mixed up as to " who she was ".
It was logged that when the police were inside the farmhouse,,that one of them heard a noise upstairs,,so they started using sign language amid whispering as they made their way upstairs.
What was the noise that they'd heard,,,and why the need to whisper orders.?
