Behind the boulder lay a trench-like depression that sloped away up the draw toward the pass. Randick dropped into it and began to crawl laboriously upward. If he could flank the Russki he could finish this with one good shot. Another explosion rocked the boulder he had just left. Randick didn't even look back.

He felt his breath rasping in his throat and his body felt hot and sticky inside the bulky pressure suit. Glancing down and to his right, he could see the proudly erect shape of his own rocket far below on the floor of the crater.

It took him almost thirty minutes to reach the edge of the shadow that spilled from the side of the mountain pass. To his left, not ten feet away, was the sudden white glare of the pumice floor. He was well above and almost behind the wreck of the Russian's ship. His flanks were heaving with the exertion of the climb as he searched the buckled mass of the crash for his opponent.

There seemed to be a dark shape wedged in between two twisted bulkheads. It looked like a man. With pounding heart, Randick murmured a prayer and lifted his bazooka, aimed, and pressed the firing stud. The shadow vanished in silent white fire.

The return blast almost knocked him down. For a moment Randick was stunned, wondering foggily where the shot had come from. Then his brain cleared and he realized that the Russki too had climbed to the pass, leaving Randick to fire at shadows.

Randick cursed himself for his dangerous stupidity. The other must be among those shadowy rocks directly across the bright floor of the pass. He raised his bazooka carefully, searching the Stygian blackness for some sign of movement. His finger curled around the firing stud....


Out of the corner of his eye he saw the flare. The Russian rocket erupted in a gout of bluish flame and the whole mountain seemed to rock. Randick stared stupidly at the glowing crater where the ship had been. For just an instant he thought that perhaps a meteorite had struck it, but the explosion had been unquestionably ... atomic.

The Russian must have been stunned, too. For he moved out into the light, empty-handed, his helmet turned woodenly toward the rapidly cooling lake of magma where his space ship had been.

They both saw the bright arc of fire that raced up from beyond the ridge and curved down gracefully toward the floor of the crater far below. Openmouthed, Randick watched his ship vanish into flame and he felt the vague tremor of the ground under him as the shock rumbled across the face of the Moon.
