Query: Major Disappointment

I love books on finance and crime. Unfortunately, this book leaves a lot to be desired. It seems that in the rush to get this book published, the author cut a few corners. For example, in one minute, Frankel is broke and being suspended by the SEC. The next thing you know, he buys an insurance company and starts expanding his empire. It is never fully explained just where Frankel's money actually come from to make these purchases. Much time seems to be spent on Frankel's deviant sexual practices, but there is precious little on exactly where Frankel's money really is. The author should have done here homework!
