A True History of Violence (and Crimefighting, Politics, and Power) In the hands of gifted cartoonist Rick Geary, J. Edgar Hoover's life becomes a timely and pointed guide to eight presidents—from Calvin Coolidge to Richard Nixon—and everything from Prohibition to cold war espionage. From a nascent FBI's headlinegrabbing tracking down of Dillinger and Machine Gun Kelly in the 1930s to Hoover's increasingly paranoid post-WWII authorizing of illegal wiretaps, blackmail, and circumvention of Supreme Court decisions, J. Edgar Hoover: A Graphic Biography provides a special window into the life of an outsized American and a bird'seye view on the twentieth century.
