and solidifies the cure. "It's bigger than Control has any idea that it is. It will take a long time yet, but we'll win. You have noticed the increase in so-called insanity in the Cowls. It really means just the opposite. Our numbers are increasing by leaps and bounds." Greg said, "The Controllers think you're using some psychological or physical pressure to create these—cures." Merrol smiled. "We've got a recruiting system. Drakeson, for example, is a spy. We have spies all over the Cowls." Greg stared. "Drakeson?" A door opened. The lean cynical man entered, nodded, and stood beside Pat. His eyes shone more brightly as he looked at Greg. "That's right," Drakeson said. "Remember the two injections. I said they were adrenolex. They weren't. Our spies inside the Cowls are equipped with a supply of a certain aggression factor. It used to be called Kappa, or K, for killer. This factor is handed down through the generations in the general cell protoplasm. It forces aggressive tendencies. It makes a man capable of physical aggressive action, and able to kill, if he has to. High motivation is required though, in most cases. With you, my probable death wasn't enough.

A warmth came out of her and into him, into his mind. Drakeson went on. "We isolated the Kappa factor, made it into solution. We all have it, even the anesthetic citizens of the Cowls, but the mass shock psychosis won't let it work. However, a strong overload of Kappa injection will sometimes break the psychosis, force the person back into an aggressive personality, capable of destruction.

Greg looked up. He grinned with a kind of glad embarrassment. "I don't know yet whether to thank you or not. Frankly though, I do feel better." He thought of the Cowls. Test-tubes, glass cages, and dreams that led finally to the final anesthesia, death. He shuddered, and tried to push the memory out of his mind. It seemed
