He undressed and climbed into the tub, relaxing luxuriously in the exhilaration of irradiated water. He let all the problems of his work drift away, his mind was a peaceful battering thunder continued persistently. He swore and sat up. "What do you want?" There was no answer the hammering continued. it should be, but the outline under the counterpane and the luxuriant mass of platinum-blond hair on the pillow was certainly no part of his regular routine. "Hello." The voice matched the calm alertness of a pair of deep-blue eyes. Brian just stared at her in numbed fascination. That was what the soon fix that. "All right, joke's over, you can beat it now." force." satisfaction of the unending extra work that was going to occur around the laboratory from now on. He sank back into the soothing liquid complete relaxation. A hammering thunder burst on the outer door. He sat up with a groan. "Say! What the—" "Where is she?" the sergeant demanded. "Wherethehell's who?" "Quit stallin', bud. You know who. That female rebel who was in here." "Rebel? You're crazy! That was just ... Pete said ... rebel? Did you say rebel?"

Haven't you caused enough blasted trouble already?" "Yes, you! If sending that damn blonde to my apartment and getting me arrested is your idea of a joke—" for months she's a rebel and she's sure been raising plenty of hell panel last night. Communications been tied up all day." Pete lowered his voice to an appreciative whisper, "Gosh, chief, I didn't know you had it in you. How long have you been in with that bunch? Is that girl as good-looking as they say she is?" "Now listen here, Brent. I don't know—" hold me here indefinitely." "Shut up. Nobody ain't takin' no message to McHague. I don't care if "Hello, pantless!" a voice breathed. He knew that voice! "What the devil are you doing here?" "Somebody by the name of Pete Brent tipped us off that you were in trouble because of me. But don't worry, we're going to get you out." cooked now. Whether you like it or not, you'll hang with us when they find us trying to get you out of here." Brian felt as though something had kicked him in the stomach. She was right! He had to get out now. He wouldn't be able to explain this away. "Give me that key," he hissed and grabbed for it. a gasping grunt of pain as one of the rebels went down. They were shooting to kill. stabbed through the darkness and they clambered precariously down a steep, steel stairway. "Where the dickens are we?" Brian whispered hoarsely. "Oh, you don't have to whisper, we're safe enough here. This is one of level tunnel. "What do we do? Hide here?" keeps up to scare people with." "That's what you think," Crystal snapped. "McHague's legend got my father and he'll get all of us unless we run the whole company right off the planet." "Well, what the dickens does he look like?" Brian asked doubtfully. before he died," she said grimly. Brian was startled at the icy hardness of her voice. going. The tunnel emerged in a huge cavern that gloomed darkly away in every direction. The towering, massive remains of old machinery, eroded and "Through that hole up there," the girl said matter-of-factly. "You're crazy, you can't get through there." almost as soon as we can walk." "Oh—I see," Brian said weakly and a few moments later he really did "Authority doesn't make much difference to them," Crystal snapped bitterly. "They've been killing people all over the planet. What do you think this revolution is about?" "You must be mistak—" He slumped to the floor as Crystal threw the ship into a mad, rolling spin. A tremendous crash thundered close saw the crew battling their controls in startled terror. The ship slipped frantically away and fell into a spin. "That's them," Crystal said with satisfaction. "How are the others doing?" jerked and jumped like crazy marionettes as the bullets smashed into them. It was over in a few moments. The dead rebels drifted down into the mist-shrouded depths of the valley. "The dirty, murdering rats!" Brian's voice ripped out in a fury of outrage. "They didn't have a chance!" "Don't get excited," Crystal told him in a dead, flat voice. "That's once in a while, you'd have heard of these things." "But why—" He ducked away instinctively as a flight of bullets spanged could not match the maneuver. The rebel craft plunged down through the blinding fog. Half-seen, ghostly fingers of stone clutched up at them, talons of gray rock missed and fell away again as Crystal nursed the " Phew! can you do it?" "Well, you don't do it on faith. Take a look at that fuel gauge! We may get as far as our headquarters—or we may not." solely by instruments and dead reckoning. The needle of the fuel gauge flickered closer and closer to the danger point. They tore loose from the clinging fog as it swung firmly to "Empty." The drive sputtered and coughed and died. "That's figuring it nice and close," Crystal said in satisfaction. "We can glide in from here." crescendoing roar of ships in a dive followed by the terrific crash of an explosion. "They got him!" Crystal's voice was a moan. "Oh, the fool, the fool!" "Sounded like more than one ship. They'll be after us, now. Is there well as we do." "How come?" two ships.

He dashed to the other ship and repeated the adjusted to critical fineness. The beat of the stuttering exhaust seemed to catch up to the other and built to an aching pulsation.

The ground shook and heaved beneath them. downward, riding the edge of the slide for terrifying minutes till it stilled and left them bruised and shaken in a tangle of torn vegetation. gone and the primeval silence settled back into place. Brian and Crystal struggled painfully to solid ground. Crystal gazed with a feeling of awe at the devastated mountainside. "How did you do it?" "It's a matter of harmonics," Brian explained. "If you hit the right vibratory combination, you can shake anything down. But now that we've made a mess of the old homestead, what do we do?"
