The Informant by Kurt Eichenwald

The Informant is Mark Whitacre, a senior executive with America’s most powerful food giant, who put his career and his family’s safety at risk to become a confidential government witness. Using Whitacre’s secret recordings and a team of agents, the FBI uncovered the corporation’s scheme to steal millions of dollars from its own customers. But as the FBI closed in on their target, they suddenly realized that Whitacre wasn’t quite playing the game they’d thought … This is the gripping account of how a corporate golden boy became an FBI mole and went on to double-cross both the authorities and his employers in one of the most extraordinary cases of global corporate corruption of the last thirty years.
