I mentioned a review of Michael Lewis’ latest in yesterday’s Beat roundup, only to realize soon after that Lewis himself has a review worth reading this week — of a new book about Warren Buffett. Here’s how Lewis starts:

There is now a long shelf of books about Warren Buffett, but this is the first time he has gone to any trouble to add to it. Reportedly Buffett now regrets his decision–he has apparently put some fresh distance between himself and his official biographer. If so, it’s not hard to see why. Alice Schroeder is a former Morgan Stanley research analyst, able to understand and to explain Buffett’s money-making, but she declined to confine herself to the business at hand. She has sought to describe Buffett’s psychological landscape as clearly as his financial one. For the reader, the results are pretty terrific–there are not a lot of 838-page narratives that leave you wanting more–but for Buffett they are no doubt upsetting.
