Based on the dust jacket, I wasn't sure what to expect. I knew it would involve finance and technology, two topics I like, but beyond that I didn't understand what the plot would involve. Basically, Dr. Hoffman, a brilliant physicist and corporate president, becomes the apparent victim of a series of events that are traced back to his own hands, calling his sanity into question. It's hard to say much more. Do yourself a favor and read the first two chapters; you'll have a better idea if it's right for you. 
 (view spoiler)[That being said, the culprit behind the strange activity was predictable. You may not guess it at first but you will guess it before the culprit is revealed. Nevertheless, the plot arc is still exciting. (hide spoiler)] 
 Don't let the technical topics scare you--the author is clearly knowledgeable about the subjects involved, but he makes it all clear and easy enough to understand. 
 The Zurich setting was a treat. I don't know much about Switzerland and I felt like The Fear Index landed me there on a direct flight. I liked the main character, his business partner, his wife, and the police detective. 
 (view spoiler)[A scene where Hoffman's business partner fires the company's risk officer was so satisfying. It was probably my favorite scene of any book I read this year. I laughed out loud. (hide spoiler)] 
 This would have been a great episode of the Twilight Zone. 
 Unfortunately, the ending was lousy.
