Move over, Harry. Make way for Alan.

Amazon.com, Inc. (NASDAQ: AMZN) has a new best-seller perched at the top of the book list. And it has nothing to do with magic. Or wait, maybe it does.

Although only on sale since Monday, the former Federal Reserve chief Alan Greenspan's personal memoir, The Age of Turbulence: Adventures in a New World, has sat at the top of the best seller list at the world's largest online bookseller. This suggests that quite a few folks are looking for answers from the often much-admired former fed chief.

And an explanation, perhaps, for all the dark alchemy currently churning the markets.

With yesterday's larger-than-expected rate cut, what is going on in the minds of bankers, corporate spenders and avid citizen economists? Everyone, even, apparently, the man on the street, wants to read -- in easy translation -- what Greenspan really thought during his generation-long tenure at the Fed. Indeed, even the book's ominous title hints that things may never be the same again.

It's ironic that the memoirs of a man who is notorious for being oblique is now a best-seller.
