Amazing that back in those days people must have been much easier to find in terms of phone numbers than today where people hardly use landlines.
SJL didn't seem to be concerned about her missing diary over the weekend, which was a busy one. Was that because she was so busy so no time to call people? She was at work on Saturday and you'd expect if she was aware it had gone missing, given it was literally the next morning after it walked, she would have been calling round from her work phone. If it was that important to her?
It's one of those things about this case that just doesn't make sense to me. If her stuff was so important, and it must have been regardless if you believe in the POW theory or not (I don't find it that convincing in the sense that she was harmed there, but for definite, it was somewhere she was planning to go, which is important), why was there no apparent concern over the weekend about it? It does suggest losing it on Sunday...doesn't mean she was present at the POW then. I am not very convinced by the phone box theory either so what else could have happened?
