Sheelah Kolhatkar is a staff writer at The New Yorker and is a former hedge fund analyst. Her book, Black Edge: Inside Information, Dirty Money, and the Quest to Bring Down the Most Wanted Man on Wall Street, tells the story of Steven A. Cohen and his involvement in the largest insider-trading scandal in U.S history. The book is one of the five finalists selected for NYPL's Helen Bernstein Book Award for Excellence in Journalism. Kolhatkar dropped by the Library to discuss how she wrote this real-life thriller, what Cohen is up to today, and why people outside of the financial world should be paying attention.
