I think Sheila's black canvas shoes were taken due to having blood spatter on them. Why else take them? I agree that is a man's slipper in the photo that Caroline posted. Looks like a courdary type with a furry inner. Doesn't that kind of place Nevill in Sheila's bedroom at some stage that night? I also noticed the piece of paper under the bedside lamp. I take it that was the note with the Please and 3's?
Also,note how Sheila appeared to like the colour blue. Blue clothes on the bed,blue eyeshadows,blue nightdress etc. I think it is fair then to assume that the pale blue socks photographed with Sheila in the main bedroom were indeed hers? Then there is the blue item of clothing hanging to dry over the bannisters. Unless it is the lighting conditions,the item does not look to be fully dry,which is interesting. We also have the blue item of clothing on the floor in the laundry room and was there a blue item of clothing near the bin in the kitchen?
In one of the documents on the forum,(maybe something to do with Paul Terzeon)there is reference to a robe with blood on the sleeve. I wonder who did this belong to,could Sheila have been wearing some kind of robe/dressing gown at some stage?
