@WendyLou,
@Dutchy, I think I've worked it out.
flooded valleys = rias
old prison warder = turnkey (after all)
punter's note = IOU (now that I've fixed the one going down)
There was another weird word for 'punter's note' which threw me.
online help = FAQs
Hope this is correct - I had to redo the whole corner and start with turnkey.
