It was not the fact of murder that had clamped the strait-jacket of forgetfulness on Lanny's mind and allowed him to think Tak Laleen had killed Barlow. He had known, for one split-second, the full maturity of the education Pendillo had given his sons. Known it too soon, with too little preparation. Now he understood why he had felt ashamed, why he'd retreated deliberately from the truth: because he had killed Barlow to resolve an old argument, not to be rid of a traitor. The method of murder had, ironically, given him the answer to Barlow's poison of despair; but because the two had happened simultaneously, the emotional shock of one had affected the other. The bursting charge of energy washed away his absurdly exaggerated sense of guilt. He achieved the mature integration he had lost before; his mind was whole again. The integration was nothing new--merely a restatement of what Pendillo had taught him, what all the treaty area teachers taught the new children. The mind of man could control the energy structure of matter. Pendillo called that rationality. But matter and energy were synonymous. The teachers had implied that without teaching it directly. A mind that could heal a body wound was also able to control the energy blast from an enemy gun. * * * * * From his father's cell Lanny heard a stifled groan. He looked back. The bars of the cell had been twisted by the blast; Pendillo was badly hurt. His wounds seemed to be extensive, but Lanny was sure his father would heal himself quickly. Lanny sprang at the guard. The Almost-man had enough courage to hold his ground, still sure of his impregnable machines. He was aiming his energy gun again when Lanny touched the opalescent capsule. That, too, was nothing now; Lanny had found his way into the new world. The field of force was simply energy in another form. Lanny could have reshaped the field, intensified it, or dissolved it as he chose. He shattered the capsule, like a bubble of glass. He smashed the gun aside. The guard stood before him, stripped of his mechanical armor--a man, facing his enemy as a man. As the guard turned to run, Lanny reached out for him leisurely. Weakly the guard swung his fist at Lanny's face. Lanny laughed and slapped at the ineffectual, white hand. The guard howled and clutched the broken fingers against his mouth. Desperately he kicked at Lanny with his metal-soled boots. Lanny dodged. The unexpected momentum sent the guard reeling and he had no efficient capsule to hold him up. He sprawled on the metal floor close to his energy gun. He grasped for the weapon as Lanny leaped toward him. For one brief moment Lanny saw madness film his enemy's eyes. Then the guard began to scream. He thrust the muzzle of the energy gun against his own chest and pressed the firing stud.
