Secret Agent X: the Legions of the Living Dead

From the pages of the September, 1935 issue of Secret Agent X comes this sensational full length novel, Legions of the Living Dead: "From nowhere hurtled that black death car. And from nowhere came its grisly occupants. They were not of the earth, for their human flesh was immune to bullets. They were not of the grave, for they manned the wheel and a blasting machine gun- Secret Agent "X" made a desperate maneuver to block their invasion of the land of the living. And in that weird terror trap, he came face to face with a man he knew-a man he knew had died five years ago!"
