Suddenly the world came to an end. There was a sheer drop-off onto the next face of the rough cube which was the asteroid. Bo lay on his belly and peered down the cliff, it ran for a couple of miles and beyond it were the deeps of space and the cold stars. He could dimly see the tortured swirl of crystallization patterns in the smooth bareness. No place to hide; his enemy was not there.
He turned the thought over in a mind which seemed stiff and slow. By crossing that little plain he was exposing himself to a shot from one of its edges. On the other hand, he could just as well be bushwhacked from a ravine as he jumped over. And this route was the fastest for completing his search scheme.
The Great Bear slid into sight, down under the world as it turned. He had often stood on winter nights, back in Sweden, and seen its immense sprawl across the weird flicker of aurora; but even then he wanted the spaceman's experience of seeing it from above. Well, now he had his wish, and much good it had done him.
He went over the edge of the cliff, cautiously, for it wouldn't take much of an impetus to throw him off this rock entirely. Then his helpless and soon frozen body would be just another meteor for the next million years. The vague downward sensation of gravity shifted insanely as he moved; he had the feeling that the world was tilting around him. Now it was the precipice which was a scarred black plain underfoot, reaching to a saw-toothed bluff at its farther edge.
He moved with flat low-gee bounds. Besides the danger of springing off the asteroid entirely, there was its low acceleration to keep a man near the ground; jump up a few feet and it would take you a while to fall back. It was utterly silent around him. He had never thought there could be so much stillness.
He was halfway across when the bullet came. He saw no flash, heard no crack, but suddenly the fissured land before him exploded in a soundless shower of chips. The bullet ricocheted flatly, heading off for outer space. No meteor gravel, that!
Bo stood unmoving an instant, fighting the impulse to leap away. He was a spaceman, not a rockhound; he wasn't used to this environment, and if he jumped high he could be riddled as he fell slowly down again. Sweat was cold on his body. He squinted, trying to see where the shot had come from.
Suddenly he was zigzagging off across the plain toward the nearest edge. Another bullet pocked the ground near him. The sun rose, a tiny heatless dazzle blinding in his eyes.
Fire crashed at his back. Thunder and darkness exploded before him. He lurched forward, driven by the impact. Something was roaring, echoes clamorous in his helmet. He grew dimly aware that it was himself. Then he was falling, whirling down into the black between the stars.
There was a knife in his back, it was white-hot and twisting between the ribs. He stumbled over the edge of the plain and fell, waking when his armor bounced a little against stone.
