Query: A Worldcom diatribe, with a few useful tidbits

Approximately 75% of this book is an eloquent rant about how the author lost his shirt on Worldcom. The remainder has some interesting takes on the stock market from a mathematical and statistical sense, and touches on a little game theory. An interesting read, but the book has little substance that could not be found elsewhere. Nice cover art, though.
