This is the third issue in the Dusty Ayres series. These are science-fiction stories of a near-future war that has ravaged America. Thousands of soldiers - air units - cannons - guarded our northern border, making a wall through which the Blacks could not, apparently, penetrate. Yet as Dusty Ayres studied that torn diagram, he knew the enemy was planning to break through, knew there was a flaw in the American defense. What was it? Could he find out in time to stop this world-destroying horde from completing the greatest military coup ever planned?
