I believe it is possible to account for the discrepancy, between account (b) and (c), because DC "Mick" Clark was at the scene, and when he was there he will have seen Sheila's body on the bed, with the bible atop and the rifle alongside her on the bed, he would have then left the scene along with Jeremy to go to 9 Head street, Goldhanger, to take a statement from Jeremy, and at this time he would have recounted to Ann Eaton, where the bodies of the five victims had been found (1) Ralph in the kitchen, (2) June on the bedroom floor by the door, (3) twins in their beds, and (4) Sheila on the bed with a bible atop her chest, and the rifle alongside on the bed...
I believe that DC "Mick" Clark, spoke about Junes body being on the bedroom floor by the door because somebody must have placed it there from the bed, before DC "Mick" Clarke entered the bedroom, and left the scene, and this would be consistent with the photograph which I saw of Sheila on the bed...
Ann Eatons account of being told by DC "Mick" Clark, that Sheila's body was on the bed with the bible atop her body and the rifle alongside on the bed, helps to explain the sequence of events with which police at the scene stage managed Sheila's body on the bedroom floor, gun atop the body, and bible alongside nearby on the carpet...
When COLP interviewed DC "Mick" Clark about the suggestion that he had told Ann Eaton that Sheila's body was found on the bed, with the bible atop of it, and the rifle alongside on the bed - he denied telling her any such thing...
But...
If there was a conspiracy involving the movement and stage managing of the scene, DC Clark would say that, wouldn't he?
