If people want to know about financial crime (and regulatory dysfunction) in the US, I absolutely second Markopolos's book with no caveats. It's a bit technical but deserves to be more widely read.

I typically recommend Browder's book with the caveat that he comes off as promotional and I think he exaggerates and makes stuff up in the first half when he was doing relatively tame things like being a consultant. This is unnecessary and hurts credibility somewhat later. However, the book is worth reading because there are extremely good insights in the latter half -- e.g. how he in effect was doing Putin's dirty work in the late 90s / early 2000s by publishing and documenting malfeasance of oligarch companies (short theses) which weakened many oligarchs and helped Putin's position vs them. Once Putin had enough clout he took down Khordokovsky; at this point, someone who pushes transparency (Browder) becomes a hindrance to the Kremlin, and things go downhill from there.
