No he was writing a book about SBF before all this went down. Probably about how awesome he was. Although you could be right and I’m sure he had some hunches it was all a mess after digging deeper. Then he got an incredible M. Night Shyamalan twist at the end.
SBF and crew were probably basking in their own genius too much to realize how most Michael Lewis books end up. They probably thought they were more Moneyball than The Big Short.
