Operator #5, America's Secret Service Ace, appeared in 48 novels in the classic pulp magazine bearing his name. From April 1934 to November 1939, Jimmy Christopher fought villains from inside the United States and invaders from without. With World War II looming on the horizon, the Operator #5 novels became a reflection of the times, showcasing American fears of technology and oppression. In Liberty's Suicide Legions, after America has been invaded and nearly destroyed, Jimmy Christopher battles the forces of the insidious Purple Emperor, with the fate of the United States hanging in the balance! One of the bloodiest pulp magazines ever produced, Operator #5 has a well-deserved reputation for thrill-a-minute action and peril.
