I highly recommend Bethany McLean’s "The Smartest Guys in the Room" to read up on Enron. Also, Lucy Prebble - who is now a consultant on HBO‘s succession - has written a nice play on the matter.
Also interesting is that sgitr is almost identical to "Bad Blood" by John Carreyrou (sp?) about Theranos. Most of the same elements were present in that fraud.
It's pretty long, but it's a good podcast, IMO. It also mentioned the book in it, and I think it was one of the main sources of information.
