In 2002 Michael Peel moved to Lagos, Nigeria, to become the Financial Times’s West Africa correspondent. His first book, A Swamp Full of Dollars, is the story of how Nigeria was shaped by the oil that pumps through western cities. A mixture of reportage, oral history and investigative journalism, it exposes the unseen consequences of reckless resource extraction. It has been nominated for the Orwell Prize. He says that if you’ve lived in a country which isn’t under a dictatorship and move to a country that has been for most of the last decade, you inevitably wonder how it is that these bloodthirsty pantomime figures came to be running the place. The dictator doesn’t become a dictator overnight, it’s a step-by-step thing - people who were genuinely admirable liberation-style heroes can turn into despots over time.
