Look at how June is placed. There is no way Jeremy "led" or "carried" (sigh) Sheila into the bedroom!
Its a mystery how she got their if she is indeed innocent, Alias. Even if Sheila had showered, which is possible, having being menstruating at the time. This could explain the clothing in the buckets.
If she had showered then she would have to had walked passed her mother to get back into the main bedroom. My theory is that it was in a perfect advantage point to watch what was happening outside from both windows of the box room where Jeaps saw a rifle leaning at the window and the main bedroom window, but that is all it a theory.
The diagram shows the doors and windows but does not tell us if those windows and doors could have been opened or accessed. Where is Hartley when you need him? Its such a shame he is no longer with us.
