Well that doesn't make sense - 'where she was not likely to go'. I'm sure she would have gone to any part of the house, especially if this is by the main door everyone used, and it was right next to the kitchen where she most likely put her clothes to soak.
I don't agree. Was she likely to have gone to the area near the back door after she'd gone to bed? She would have had to go through the kitchen and out of the kitchen door. I don't know where the clothes were left in the bucket though, so perhaps you have a point.
Yes, but depending on what time Jeremy left, how was he to know the movements of everyone? Lots of people 'potter about' before they go to bed - even sorting out washng for next day.
Sheila's autopsy/post mortem showed she had undigested food in her stomach, and although her mother told Pamela that Sheila was going to bed, there's nothing to say she actually went to sleep, therefore she could have gone downstairs again to get something to eat. If she had gone wandering up into the attic then maybe that would have been strange.
