It never seems to end but it does end in the end.
14 pages to go out of around 503,000 words [around 1437 dead tree pages], calling it a night at 20:45.
Need to put a final twist into those 14 pages and then, unfortunately, go back through the book again and add references to that at intervals – I know specifically where.
Then half a day on navigation and that will be about it. Tomorrow.
