Holly, please answer this:
You think Nevill phoned Jeremy before he was shot, and said Sheila’s going crazy with a gun. In order for him to know she had a gun he would either have had to see her with one or have heard the shots. If he saw her with the gun first, then he must have encountered her downstairs before the shooting had begun, so why did he stay downstairs and not rush up the stairs as soon as he heard the first shot being fired? In fact why did he wait downstairs until all the shooting had finished upstairs, whilst still on the phone waiting for Sheila to come back downstairs and cut the phone off? Ah, but hang on, Nevill did go upstairs and get shot, which must have happened after the phone call that Sheila cut him off during because he wouldn’t have been able to speak after being shot, well why didn’t she shoot him downstairs then, why did she allow him to follow her up the stairs? No, I can’t make any of this make any sense. Help!
