of smoke marked its end. Another blew up. And another— The Niccola’s rockets faithfully blew themselves to bits on command from the Niccola’s own weapons control. There was nothing else to be done with them. They’d been taken over in flight. They’d been turned and headed back toward their source. They’d have blasted the Niccola to bits but for their premature explosions. There was a peculiar, stunned hush all through the Niccola. The only sound that came out of any speaker in the radar room was Taine’s voice, high-pitched and raging, mouthing unspeakable hatred of the Plumies, whom no human being had yet seen. Baird sat tense in the frustrated and desperate composure of the man who can only be of use while he is sitting still and keeping his head. The vision screen was now a blur of writhing mist, lighted by the sun and torn at by emptiness. There was luminosity where the ships had encountered each other. It was sunshine upon thin smoke. It was like the insanely enlarging head of a newborn comet, whose tail would be formed presently by light-pressure. The Plumie ship was almost invisible behind the unsubstantial stuff. But Baird regarded his radar screens. Microwaves penetrated the mist of rapidly ionizing gases. “Radar to navigation!” he said sharply. “The Plumie ship is still approaching, dancing as before!” The skipper said with enormous calm: “Any other Plumie ships, Mr. Baird?” Diane interposed. “No sign anywhere. I’ve been watching. This seems to be the only ship within radar range.” “We’ve time to settle with it, then,” said the skipper. “Mr. Taine, the Plumie ship is still approaching.” Baird found himself hating the Plumies. It was not only that humankind was showing up rather badly, at the moment. It was that the Plumie ship had refused contact and forced a fight. It was that if the Niccola were destroyed the Plumie would carry news of the existence of humanity and of the tactics which worked to defeat them. The Plumies could prepare an irresistible fleet. Humanity could be doomed.
