Before we could commence our undertaking, word reached Washington that the rumors were now actualities. A device capable of the mass hypnosis of great segments of the world's population was rapidly reaching perfection. After three months of intensive grooming in the fields of physics and psychology, we four agents set out individually with orders to track down and destroy both the scientist and his machine. I never saw the other three again....
