Unfinished tapestry

Scott's Australia news has made me realise that our next adventure will probably be our last.
This means that all the plot threads I've left dangling, need tying up.
Yes, of course there's a plot!
Some of them are down to clues not found or questions not asked but most of them are just down to me and shortage of time.
I'll try to post some of the clues/answers up over the next month and wrap as many of the others during the next session's actual gameplay...
