Query: fascinating candour

This book provides an excellent expose of the derivatives and investment banking trade in surprising detail. I found the step-by-step explanations of how the derivative products were engineered and where the banks were making money most fascinating! The author has confirmed my personal belief that investment banks,just like the 'banker' in a casino,clearly has the upperhand when it comes to derivatives trading. Play at your own risk.Finally, if anyone doubts any of the facts presented, one bank (mentioned in the book) was recently suspended in Japan for engaging in one of the very derivatives scams highlighted by the author.
