She gripped his shoulders. The touch did things to Venard's nervous system. Forgotten things. "But it's useless," she said, "for you to try such a scheme here, Karl. The Martians, for all their military might, are just insignificant pawns." Venard exclaimed, "Martians--just pawns! You haven't been around lately. Those babies have taken over everything, and they intend to keep it. This other menace ... don't be so mysteriously evasive, Vale. Who, or what, is this _it_? Don't tell me the Martie desert tribes' rumors about an alien god controlling S.S.C. is authentic!" She tried to answer, but she swayed, shut her eyes, and clenched small white fists. Her body twitched violently, blood drained from her face. He shot an arm about her waist, but she was stiff, cold and unyielding. And this was too abnormal. Her head fell back over his arm. Then she opened her eyes slowly. They were glazing, dulling, as though being seared by a minute but horrific flame. Her lips moved stiffly. "It--back--jo--jo--" He was holding her that way when the door slid noislessly open and they filed through. * * * * * He hated them thoroughly--the weird polyglot of selfish recluses, without purposes here in their rotten, sequestered borough.

They were neutrals with a strict mutual code of hands off with all other planets. They were the sociopaths of the System. They had never entered the Federation, even on paper. Isolationists who-- * * * * * Then he knew. Without that clue from poor Vale, he might never have found out the truth until it was too late. If it wasn't already much too late. "_Jo--Jo--_" just what she had been trying to tell him. The menace to the Solar System that made even the Martians only insignificant pawns were the unknown completely ignored Jovians! The Martians pawns of these little--impossible. No, not impossible. The Jovians were mysteriously uncatalogued. They possessed telepathic power by which they communicated with each other. But no being of any other planet had ever been able to communicate with a Jovian--as far as anyone knew. It was said that it demanded some time for a Jovian to familiarise itself with highly individualized brain-wave patterns. But when they did, they were supposed to be able to control that mind--
