The place: Detroit. The time: World War II. While most of the police department is fighting overseas, the four men of the Racket Squad struggle to keep a lid on a powderkeg stuffed with draft-dodging troublemakers, Black Market gangsters, enemy saboteurs, and a mixed bag of racial and ethnic groups working uneasily side by side in defense plants run by the automobile industry. With blackjacks, brass knuckles, tommy guns, and their bare fists, Lieutenant Max Zagreb, Sergeant Starvo Canal, and detectives McReary and Burke—known collectively as the "Four Horsemen"—battle their way through ten gritty stories in the hardest-boiled town during the twentieth century's hardest-boiled decade.
