It was only a matter of time before a glut of these books arrived on the market and I would suggest choosing carefully to any reader.
Fox presents a comprehensive account of Enrons progession from sleepy pipeline company to a sprawling pseudo-Investment Bank tunnel-visioned on global domination. The key players in the story are painted with strong definition and the author really gives you a feel for who they were and what made them tick. Ken Lay is portrayed as palm pressing figurehead concerned with influencing legislation by getting closer to Washington and seemingly unaware of the deceit going on beneath him. Jeff Skilling is seen as the man who transformed Enron into a slick sales and trading operation modelled on an investment bank, driven only by money and willing to stop at nothing to achieve his goals. It is probably the CFO Andrew Fastow who comes accross as the main villain and Fox goes into implicit detail to describe the intricate financial structures he used to hide Enrons debt and (sometimes) profit personally from this.
Anyone who is not familiar with Banking and Finance jargon will find themselves reading the same page 4 or 5 times over to get their heads around Fatows "special purpose vehicles" but this aside, it is a very well-written book.
