by BASIL WELLS Marooned on a world within a world, aided by a slim girl and an old warrior, Patrolman Sisko Rolf was fighting his greatest "Trapped us neatly," Rolf said through clenched teeth. "Tolled into Planet Patrol ship as he swung the deadly slimness of his rocket blast's barrel around to center on the fiery jets that betrayed the Rolf swung the lax controls over hard as the bursts of fire revealed a In a slow sort of wonder Rolf felt the scrape of rock against metal, found the strength to wrap his fingers around the control levers and snap on a quick burst from the landing rockets. Their mad speed checked split open like a rotten squash, and Rolf felt himself Much later Rolf groaned with the pain of bruised muscles and tried to heat from the yet-glowing debris of the rocket flyer. The outlaws had Rolf capped the solar torch. No use wasting the captive energy needlessly he reasoned. And he loosened the expoder in its holster as the other half. Toward this barrier the spinner bore him, and Rolf was it seemed to Rolf that he must be falling free through black dust, and he came to a stop. Deftly Rolf nested the rocks ahead. Rolf's slitted gray eyes narrowed yet more and his hand Rolf found himself staring, open-mouthed, at the sleek-limbed vision The girl laughed, a low liquid sound that made Rolf's heart pump faster. "This Mark Tanner of mine," she explained to the patrolman, "is always afraid for me. He does not remember that I can see into the minds of others." She smiled again as Rolf's face slowly reddened. "Do not be ashamed," Rolf threw up the mental block that was the inheritance from his grueling years of training on Earth Base. His instructors there had known that a few gifted mortals possess the power of a limited telepathy, and the secrets of the Planet Patrol must be guarded. "Sorry," said the tall man as Rolf sprang easily from the ground to Rolf followed the direction of the other's pale blue eyes. Overhead now lifted above the restless dark waters of a vast sea. Rolf realized with Rolf felt new strength pump into his tired bruised muscles. Here lay "Mark!" The girl's voice was tense. Rolf felt her arm tug at his sleeve A hundred paces away Rolf made the dark shapes of armed warriors as Rolf watched the column of barbarically clad warriors file out upon the Spear tips and bared swords glinted dully. "They will pass within a few feet!" he hissed. "Right." Tanner's fingers bit into Rolf's arm. "Pray that the wind does Rolf's eyes slitted. There was something vaguely unhuman about those utterly shoulderless, and beneath their furry pelts the ripples of smooth-flowing muscles played rhythmically. There was a stench, a musky penetrating scent that made the flesh of his body crawl. "See!" Tanner's voice was muted. "Giffa, Queen of the Furry Ones!" she was, her scarred gray-furred hide hanging loose upon her breastless Rolf raised his expoder, red anger clouding his eyes as he saw these races mingled they hate the Furry Ones." A shadow passed over their hiding place. The Furry Amazons too saw the Rolf and Mark Tanner came to their feet. Rolf's expoder rattled briefly like a high-speed sewing machine as he flicked its muzzle back and forth along the ranks of attacking Furry explosive blasted them but hundreds more were swarming over their fallen sisters. Mark Tanner's bow twanged again and again as he drove arrows at the bloodthirsty warrior women. But the Furry Ones ran The expoder hammered in Rolf's heavy fist. Tanner smashed an elbow into Rolf's side. "Retreat!" he gasped. The Furry Amazons swarmed up over the lower terraces of rocks, their "Now where?" Rolf snapped another burst of expoder needles at the furry The bald scientist slung his bow over his head and one shoulder and the heart of the Barrier. Rolf blasted another spurt of explosive shattered heart. An unseen furry shape sprang upon Rolf's shoulders neck. His fist sent the attacker's bulk smashing against the rocky Tanner's finger pointed. "Altha!" Rolf saw the graceful wings of the "The weasel heads won't follow us here?" asked Rolf. Rolf laughed. "Like the pleasure globes of the wealthy on Earth." "But," Rolf frowned thoughtfully, "what keeps Lomihi from crashing into Rolf caught a glimpse of a sleek rocket flyer diving upon Altha's frail section of the wall swung slowly inward. Rolf sprang to his side. The older man's eyes were hot. He jerked at Rolf's hands and then Rolf pushed up and outward with all the strength of his weary muscles. over the Barrier. The Furry Ones were struggling insect shapes below him, and he saw with a thrill that larger bodied warriors, whose bodies glinted with a dull bronze, were attacking them from the burnt-out A man stood on guard just outside the flyer's oval door. Rolf lined up comrades. But if the outlaw saw him Rolf knew that he would be the first to fire—his was the element of surprise. A score of feet lay between them, and suddenly the outlaw whirled about. Rolf pressed the firing button Rolf snapped his weapon overhand at the Frog's hairless skull. The fish-bellied alien ducked but his expoder swung off the target momentarily. In that instant Rolf launched himself from the open They went down, Rolf swinging his fist like a hammer. He felt the Frog go limp and he loosed a relieved whistle. Now with a rocket flyer and the guard's rifle expoder in his grasp the problem of escape from to save into the shelter of the flyer.

The odds were evening, he thought triumphantly. There might be another This sledge was hammering relentlessly as Rolf sensed his first as he moved his arm. But Rolf had learned that his limbs were not By degrees Rolf worked his arm down to his belt where his solar torch Rolf heard voices from a distance and the answering triumphant bawling "Fire!" There was panic in the outlaw's voice. Rolf came to his knees not on the prisoners, and so the impact of Rolf's horizontally The outlaw was game. His fists slammed back at Rolf, and his knees jolted upward toward the patrolman's vulnerable middle. But Rolf bored in, his own knotted hands pumping, and his trained body weaving instinctively aside from the crippling blows aimed at his body. For a smoke, and then the fingers of the outlaw clamped around Rolf's throat Rolf swung, all the weight of his stocky body behind the blow, and the outlaw thudded limply against the opposite wall of the little cabin. "Glad of that." Rolf felt the warmth of her body so close beside him. A Rolf grinned up at her. "Need to?" he asked. Then they were over the Barrier and Rolf saw the last of the beaten Furry Ones racing back across the great wall toward the Plains of Rolf snorted.
