Billions of dollars stolen from citizens are circling the globe, enriching powerful individuals, altering political outcomes, and disadvantaging everyday people. Where does one begin to fight corruption of this magnitude? To find answers, this book examines the corruption crisis that erupted during the recent oil boom. Telling stories drawn from cases of corruption around the world, the book reveals how company bosses have signed off on risky schemes, kleptocrats have used oil wealth to cement their hold on power, and armies of bankers, accountants, and lawyers have stashed the stolen loot offshore. However, these stories also reveal vulnerabilities in this web of fraud and show how prosecutors, journalists, and activists have succeeded in battling back. These are the starting points for building a smarter fight against corruption, in the oil sector and well beyond.
