ok, so mm is reading a new book...the flanders panel......quite compelling for a suspense novel/chess lesson.......the premise is a flemish painting of 2 men playing chess with a woman in black watching........words seen only upon xray prior to restoration/auction are mysterious......who took the knight? (or who killed the knight, depending on translation of choice.........) so the story is about the restorer who is trying to find out who the people pictured were, and if the 'knight' in the picture was in fact killed.....you get it.......the plot requires that the chess game in the picture be replayed/backtracked.......quite interesting.......
