Rob tucked an electron gun in the holster of his suit, then left the _Centaurus_. He struck out over the glacier pack, his head lowered. It came to him then how difficult it would have been for the men to detect any moving object in the murky maze below. Hours passed and Rob found himself far from the ship. He was shivering from the stubborn cold. He turned the heat in his suit to full strength and pushed his aching legs faster to speed up the circulation. His eyes never left the ground, searching, searching.... If he were the only one involved in the failure, it wouldn’t matter so much, but it was his brother’s problem too. Grant hadn’t made many mistakes on research expeditions—that was why he held the highest office in the organization. After this, though, it would go hard with him. Then there was the misunderstood Dr. Franz, who deserved a better fate than being labeled an old man who in his final days seemed to have lost his clear, scientific outlook. “Maybe, though, the public was right,” Rob thought. “Maybe it was a hoax Dr. Franz pulled in order to gain public recognition he had never quite made.” But even now, in the blackest moment, Rob couldn’t really believe this of the dear friend who had launched his brother’s career. Rob’s legs were beginning to feel like stumps as the time dragged on. He stumbled often on burls of ice that cluttered the wasteland. Finally he tripped and fell heavily, and it seemed that he did not even have the strength to rise again. His helmet was flat on the ice and his eyes, misted over with sleeplessness, were still looking downward. _Then he caught a sign of movement in the depths._ He blinked his eyes to clear the glaze out of them. “There it is again!” he said aloud. “It’s no hallucination either!” It was a long dark shape threading its way sluggishly down below. Now the thing was rising to the surface. Cold, bulging eyes peered into his own. With numb fingers Rob uncached his electron gun and pressed the barrel against the ice. A moment later the creature was hanging buoyant and lifeless under the submerged edge of the ice layer. Rob struggled to his feet, astounded at the renewed energy he now had. He memorized the spot as best his dazed faculties would allow. Then he laid the pistol on the ice for an additional marker. He began running toward the ship. From that moment on, Rob’s mind seemed to be in a dream world. He vaguely remembered the long way back to the space ship and then nearly collapsing before reaching it. He dimly remembered Jim, who had missed him, coming outside and assisting him into the warmth of the vessel. And he barely recalled pouring out the story of his find. Now, much later, he was fully awake and the nightmare was over. He found himself on his cot, fully dressed. Jim Hawley was looking down on him. Rob was aware that the ship was moving. He knew the _Centaurus_ had already blasted off for home. “Did you find—!” he exclaimed.
