McLean, now a senior writer for Fortune, joined the financial magazine's reporting staff in 1995. In that capacity she covers a wide range of companies and industries and also contributes to the "Street Life" column for Fortune's online publication, fortune.com.
Her story, "Is Enron Overpriced?" was published in the March 2001 issue of Fortune. Two years later, McLean's book, co-written with colleague Peter Elkind, was published. The Smartest Guys in the Room chronicles the scandal and is considered by many as the definitive account of the Enron debacle. Prior to becoming a writer, McLean worked in investment banking.
