Secret Agent X #9: Servants of the Skull

They called Secret Agent "X" the Man of a Thousand Faces. Armed with his irresistible gas gun, wearing impenetrable disguises, "X" infiltrated the darkest corners of the Underworld to crush all crime czars!

From the macabre maze of a labyrinthine world, the Skull, master of murder, reached out and destroyed the brains of mighty financiers. Money kings were his meat. And the law could not protect them....

Only one man could match brains with the sinister Skull, and that man was Secret Agent "X". But the Skull did not fear "X". For "X" - the Man of a Thousand Faces, a thousand personalities, a thousand tricks - had one vulnerable spot. And the Skull knew where it lay.
