not." The captain was momentarily silent, groping for an adequate reply. Behind him somebody made a choked noise, the only sound in the stunned hush, and the ship jarred slightly as a thunderbolt slammed vengefully into its field. , as for forty hours the ship had decelerated. They had seen many such stars come near out of the galaxy's glittering Quest III the most hopeful of the expeditions—and its captain had been a good friend of Llud's, nine hundred years ago.... He growled, "What happened to him?" backdrop, and had seen them dwindle, turn red and go out as the time," said the voice lightly. "When he saw that it was hopeless, he preferred suicide to defeat, and took his ship into the Sun." A short pause. "The vision connection is ready." "He fought off our interceptors, which are around you now, for some crew. It was a subdued excitement but undeniably a man's. His features and his light-brown skin showed the same racial characteristics possessed by those aboard the Quest men and women, they out from its original cramped quarters. Now the interstellar ship was little more than a hollow shell. Eyes lifted from the vision screens to interrogate Knof Llud we left, the world we knew and fitted in...." The captain put an arm round her with comforting pressure. "Don't worry. Things may have changed—but we'll manage." But his face had hardened against registering the gnawing of that same doubtful fear within him. He let his arm fall. "I'd better get up to the bridge. There's a new course to be set now—for Earth." Sun, mirrored and multiplied by the screens. In that light Lesra's eyes gleamed with unshed tears. Captain Llud found Navigator Gwar Den looking as smug as the cat that ate the canary. Gwar Den was finding that the actual observed positions of the planets thus far located agreed quite closely with forgotten altogether." He turned away grim-lipped and left the bridge. From his private then he sat idle, alone with his thoughts. The ship's automatic mechanisms had scant need of tending Knof Llud found himself wishing that he could find some back-breaking task for everyone on board, himself included, to fill up the hours that remained. and watch the screens, or to the family apartment where he might find Lesra and the children—but somehow he didn't want to do that either. He felt empty, drained—like his ship. As the Quest III's and the hope of success in man's mightiest venture had dwindled, so the strength had gone out of him. Now the last fuel compartment was almost empty and Captain Knof Llud felt tired and old. Perhaps, he thought, he was feeling the weight of his nine hundred Earth years—though physically he was only forty now, ten years older than when the voyage had begun. That was the foreshortening along the expedition, a segment of his life and of history. He might add that to the ship's official log and its collections of scientific data, as a report to whatever powers might be on Earth now—if such powers were His own voice came from the speaker, fresher, more vibrant and confident than he knew it was now. "One light-day out from Procyon, the thirty-third day by ship's time since leaving Earth. Procyon had possessed a habitable planet, we could have returned after an absence of not much over twenty years Earth time. "It is cheering to note that the crew seems only more resolute. We go ships will be long since dead. Nevertheless we go on. Our generation's dream, humanity's dream, lives in us and in the ship forever...." Presently Knof Llud switched off that younger voice of his and leaned back, an ironic smile touching his lips. That fervent idealism seemed remote and foreign to him now. The fanfares of departure must still have been ringing in his ears. we cannot betray the plan.... This may be man's last chance of escaping his pitiful limitation to one world in all the Universe. Certainly the building of this ship and its two sisters, the immense expenditure of time and labor and "Would the crew be willing? I don't know—some of them still show signs of homesickness, though they know with their minds that everything that was once 'home' has probably been swept away.... "It doesn't matter. Today I gave orders to swing the ship." Savagely Knof Llud stabbed the button that shut off the speaker. Then he sat for a time with head resting in his hands, staring into nothing. once in translation from the ancient English.... ... for my purpose holds To sail beyond the sunset, and the baths Of all the western stars, until I die. Llud sighed. He still couldn't say just why he had given the order to turn back. The stars had claimed his heart—but he was still a part of Earth, and not even nine hundred years of space and time had been able to alter that. glittering constellations, far away, out of reach.... He wasn't sure he would want to do that, though. Suddenly a faint cushioned jar went through the great ship it seemed to falter one moment in flight. The captain was on his feet instantly, but then his movements became unhurried. Whatever it had been was past, and he had a good idea the vessel. Llud snatched up the receiver with the speed of a scalded cat. "Captain?" It was Gwar Den's voice, stammering a little. "Captain, interstellar ship. Knowing that Gwar Den was still there, he said, of horsepower behind them but it plunged on toward Earth, its mighty engines still steadily braking its interstellar velocity. To a man, the ship's responsible officers were already on the bridge, most of them breathless. To a man they looked appeal at Captain Knof Llud. Gwar Den spoke. "There are thirteen of them out there now, sir, and he had confidence in his father. "If they had anything heavier," surmised the captain, "they'd have unlimbered it by now. They're out to get us. But at this rate, they the ship forces impinging on the outside of the field were similarly transmitted and rendered harmless. The effect was as if the vessel and all space inside its field were a single perfectly elastic body. A meteoroid, for example, on striking it rebounded—usually vaporized by the impact—and the ship, in obedience to the law of equal and opposite forces, rebounded too, but since its mass was so much greater, its deflection was negligible. inertialess drive, at its normal thrust of two hundred gravities, was intentionally operated at one half of one per cent efficiency to provide the illusion of Earthly gravitation. bridge looked questions at each other, as the thought of help from outside flashed into many minds at once. But Captain Llud said soberly, "It must have caught one of their own shots, reflected. Maybe its own, if it scored too direct a hit." Gwar Den had at first supposed—not large enough to hold even one man. it. Elsuz Llug, the gravitic engineer, calculated dismally, "At the rate swinging wild and then you nail him." Smiles splintered the ice of tension. Captain Llud said, "Maybe you've got something there. They seem to be mad, all right. But we're not in you ?" There was no answer. The ship drove on, its fuel trickling away under multiplied demands. Those outside were squandering vastly greater too. Once more Knof Llud had the insidious sense of his own nerves and muscles and will weakening along with the power-sinews of his ship. Zost Relyul approached him apologetically. "If you have time, and likewise the ultraviolet up to the point where the atmosphere is opaque to it." The captain sighed wearily. "Good work," he said. "Keep it up perhaps you can answer some of these riddles before—"
