I still can't envisage the circumstances in which a telephone call was made from White House Farm by Ralph(Nevill). Does he hear Sheila going into the twins' bedroom and hear the shots she fires into their bodies,then comes out onto the landing where he is shot four times,Sheila then goes into the master bedroom and shoots June,during which time Nevill manages to stagger downstairs..however he doesn't make for the gun cupboard but the telephone in the kitchen. Let's say Nevill at this stage knows he is wounded too badly to manipulate a gun,but with one hand can dial a number..it's an emergency situation as he relates to Jeremy that "Your sister has gone crazy and has got the gun" which is echoed in Jeremy's call to the Police from Goldhanger("You've got to help me..")..whilst Sheila is shooting June seven times Nevill manages to make another phone call to the Police,which is logged as "daughter gone berserk with one of my guns".
At this stage in the scenario therefore Nevill has already made two telephone calls from the kitchen. Nevill then has a little more time to twist his bloodstained watch off his wrist and hide it under the rug,before Sheila comes back into the kitchen where she bashes him brutally in the head,then fires three more times to finish him off.
I'm wondering why,when Nevill manages to get downstairs in a fight or flight situation if ever there was one he wastes time phoning what must have at least been a 7 figure number to Jeremy when one's only thought must be for the safety of those upstairs? The 999 number would have been in anyone's mind first especially since he is injured with his motor skills impaired. There is no blood on the downstairs phone,yet we know from the wristwatch that he had been wounded,unless he somehow in his dying moments manages to unfasten his wristwatch and hide it under the rug.
I would suggest that it's far more likely that it was Jeremy whom Nevill heard moving about in the early hours of that morning and tried the bedroom phone which was disabled as Jeremy had already unplugged the kitchen phone which was later proved to be in working order. Nevill comes out of the bedroom and Jeremy shoot him four times,then goes into the master bedroom where June is shot seven times in total,the first as she is sat up in bed,one shot aimed straight between the eyes.
Nevill is then frogmarched downstairs by Jeremy to the kitchen- in Dr. Vanezis's report there are marks on Nevill's back to suggest that a hot rifle butt is held against his skin for a short period,where he is then assaulted with the rifle and left for dead. Nevill manages to release his wristwatch and hide it under the rug,hoping against hope that its bloodstained state might be useful to investigators. Jeremy then races back upstairs,finishes June off,hurries back downstairs and fires three more bullets into Nevill,which prove fatal.
I just don't see a scenario where Nevill makes any telephone calls to the Police that morning. I can see a scenario where another person,whether Jeremy or a hitman does make a call,with gloved hand on the kitchen phone to the cottage at Whitehanger,which if records do exist,would show that calls were made,but not by whom.
