And Heym ben-Hillel, the Israeli quantum and wave-mechanics man, his heaping dinner plate an affront to the Laws of Moses, his white hair a fluffy, tangled chaos, laughing at an impassively-delivered joke the English knight had made. And Rudolf von Heldenfeld, with a thin-lipped killer's mouth and a frozen face that never betrayed its owner's thoughts—he was the specialist in magnetic currents and electromagnetic fields. And Farida Khouroglu, the Turkish girl whom MacLeod and Karen had found begging in the streets of Istanbul, ten years ago, and who had grown up following the fortunes of the MacLeod Team on every continent and in a score of nations. It was doubtful if she had ever had a day's formal schooling in her life, but now she was secretary of the Team, with a grasp of physics that would have shamed many a professor. She had grown up a beauty, too, with the large dark eyes and jet-black hair and paper-white skin of her race. She and Kato Sugihara were very much in love. A good team; the best physics-research team in a power-mad, knowledge-hungry world. MacLeod thought, toying with the stem of his wineglass, of some of their triumphs: The West Australia Atomic Power Plant. The Segovia Plutonium Works, which had got them all titled as Grandees of the restored Spanish Monarchy. The sea-water chemical extraction plant in Puerto Rico, where they had worked for Associated Enterprises, whose president, Blake Hartley, had later become President of the United States. The hard-won victory over a seemingly insoluble problem in the Belgian Congo uranium mines——He thought, too, of the dangers they had faced together, in a world where soldiers must use the weapons of science and scientists must learn the arts of violence. Of the treachery of the Islamic Kaliphate, for whom they had once worked; of the intrigues and plots which had surrounded them in Spain; of the many attempted kidnappings and assassinations; of the time in Basra when they had fought with pistols and tommy guns and snatched-up clubs and flasks of acid to defend their laboratories. A good team—before the rot of treason had touched it. He could almost smell the putrid stench of it, and yet, as he glanced from face to face, he could not guess the traitor. And he had so little time— Kato Sugihara's voice rose to dominate the murmur of conversation around the table. "I think I am getting somewhere on my photon-neutrino-electron interchange-cycle," he announced. "And I think it can be correlated to the
