A contract has already been cut with former Time and Fortune writer Richard Behar for a book on ponzi schemer Bernie Madoff, arrested one week ago today. Joe Nocera, ear your heart out!

That was fast. Four of the business writers said last week to be hunting for Wall Street crisis book deals have found publishers — the same publisher. Penguin Group swears it wasn't bumbling when it hired the authors in rapid succession, at a cost of more than $2 million, to basically compete with one other. What does Penguin look like, some kind of investment bank? "I would rather be publishing all three of the best books on the economic crisis than to be competing against any one of them," Penguin's president told the Observer. OK, but who's going to buy these tomes?

Bankers' losses are going to be certain authors' gains: Book proposals about the Wall Street debacle have already landed on publishers' desks, reports Leon Neyfakh in the Observer. Times business columnist Joe Nocera (right) and former Fortune reporter Bethany McLean (left) are asking for offers in excess of $1 million for their "definitive chronicle" of the financial crisis, and Newsweek's Daniel Gross is pitching a "quickie electronic book" with a similar premise. Meanwhile, Publishers Marketplace reports that Melanie Jackson has sold Roger Lowenstein's Six Days That Shook the World, "a look at last week on Wall Street and in Washington, illuminating the origins of the crisis," to Ann Godoff at Penguin.

"Bethany McLean, co-author of a best-selling book about the Enron debacle, is leaving Fortune after a 13-year run to jump to Graydon Carter's Vanity Fair... It marks at least the third time that Condé Nast, which is headed by billionaire chairman S.I. Newhouse, Jr., has come calling on McLean, one of the higher-profile journalists at the Time Inc.-owned business magazine. Portfolio had tried to get her to jump ship a year ago when Condé Nast was launching its business magazine, but Time Inc. editor-in-chief John Huey intervened to help Fortune win that tug of war."
