Into the arena of the endless war which society wages on the criminal has stepped a new and gallant warrior - Dan Fowler, special agent of the Department of Justice. Tireless, vigilant, and daring, Dan faces the sinister forces of the underworld, determined to wrest the stranglehold of crime from the throat of humanity! Armed with courage and an insuperable power of strategy and deduction, he pits all his strength and energy against the gangster and the racketeer.
The Grey Gang was the most vicious criminal kidnapping ring in the nation. Ordinary police could not capture them. Their victims mounted. So J. Edgar Hoover assigned his top G-Man to track them down. Special Agent Dan Fowler was the right man for the job. Tough as nails, cool under fire, he was as relentless as his enemies were cruel. Fowler swore an oath to crush these murderous specialists in the snatch racket. It was his job. But it was also personal.
