Edgar Hoover transformed a failing law-enforcement backwater into a modern machine. He stayed in power for decades, and created a personal fiefdom unrivalled in US history. In this masterful, multi-award-winning biography, Beverley Gage explores the full sweep of Hoover’s life and career. In Gage’s portrait, Hoover was a man admired by millions, but was also a formidable public figure who intimidated his enemies, excluded minorities from his great American project and created the foundations of the US far right. G-Man is a dramatic portrait of one of America’s most influential – and controversial – public figures. It is also an engrossing story of the making of modern America.
