"Conway! Hurry! Oh, hurry! I can't last much longer--good-bye, dear!" In the horror-filled tones both men read clearly the girl's dire extremity. Each saw plainly a happy, care-free young earth girl, upon her first trip into space, locked inside an ether-wall with an over-brained, under-conscienced human machine--a super-intelligent but lecherous and unmoral mechanism of flesh and blood, acknowledging no authority, ruled by nothing save his own scientific drivings and the almost equally powerful urges of his desires and pas-sions! She had fought with every resource at her command. She had wept and pleaded, she had stormed and raged, she had feigned submission and had played for time--and her torment had not touched in the slightest degree the merciless and gloating brain of the being who called himself Roger. Now his tantalizing, ruthless cat-play was done, the horrible gray-brown face was close to hers--she

wailed her final despairing message to Costigan and attacked that hideous face with the fury of a tigress.
Costigan bit off a bitter imprecation. "Hold him just a second longer, sweetheart!" he cried, and the power room door vanished. Through the great room the two Lewistons swept at full aperture and at maximum power, two rapidly opening fans of death and
destruction. Here and there a guard, more rapid than his fellows, trained a futile projector--a projector whose magazine exploded at the touch of that frightful field of force, liberating instantaneously its thousands upon thousands of kilowatt-hours of stored-up energy. Through the delicately adjusted, complex mechanisms the destroying beams tore. At their touch armatures burned out, high-tension leads volatilized in crashing, high-voltage sparks, masses of metal smoked and burned in the path of vast forces now
seeking the easiest path to neutralization, delicate instruments blew up, copper ran in streams like water. As the last machine subsided into a semi-molten mass of metal the two wreckers, each grasping a brace, felt themselves become weightless and knew that they had accomplished the first part of their program.
Costigan leaped for the outer door. His the task to go to Clio's aid.... Bradley would follow more slowly, bringing the girl's armor and taking care of any possible pursuit. As he sailed through the air he spoke.
"Coming, Clio! All right, girl?" Questioningly, half fearfully.
"All right, Conway." Her voice was almost unrecognizable, broken in retching agony. "When everything went crazy he ... found out that the ether-wall was up ... forgot all about me. He shut it off ... and seemed to go crazy, too ... he is floundering around like a wild man now.... I'm trying to keep ... him from ... going down-stairs."
"Good girl--keep him busy one minute more--he's getting all the warnings at once and wants to get back to his board. But what's the matter with you? Did he ... hurt you, after all?"
"Oh, no; not that. But I'm sick--horribly sick. I'm falling.... I'm so dizzy I can scarcely see ... my head is breaking up into little pieces
... I just know I'm going to die, Conway! Oh ... oh!"
"Oh, is that all!" In his sheer relief that they had been in time, Costigan did not think of sympathizing with Clio's very real present distress of mind and body. "I forgot that you're a ground-gripper--that's just a little touch of space-sickness. It'll wear off directly.... All right, I'm coming! Let go of him and get as far away from him as you can!"
He was now in the street. Perhaps two hundred feet distant and a hundred feet above him was the tower room in which were Clio and Roger. He sprang directly toward its large window, and as he floated "upward" he corrected his course and accelerated his pace by firing backward at various angles with his heavy service pistol, uncaring that at the point of impact of each of those shells a small blast of destruction erupted. He missed the window a trifle, but that did not matter--his flaming Lewiston opened a way for him, partly through the window, partly through the wall. As he soared through the opening he trained projector and pistol upon Roger, now almost to the door, noticing as he did so that Clio was clinging convulsively to a lamp-bracket upon the wall. Door and wall
vanished in the Lewiston's terrific beam, but the pirate stood unharmed. Neither ravening ray nor explosive shell could harm him--he had snapped on the protective shield whose generator was always upon his person.
But Roger, while not exactly a ground-gripper, did not know how to handle himself without weight; whereas Costigan, given six
walls against which to push, was even more efficient in weightless combat than when handicapped by the force of gravitation. Keeping his projector upon the pirate, he seized the first club to hand--a long, slender pedestal of metal--and launched himself past the pirate chief. With all the momentum of his mass and velocity and all the power of his mighty right arm he swung the bar at the pi-rate's head. That fiercely driven mass of metal should have taken Roger's head from his shoulders, but it did not. That shield of force was utterly rigid and impenetrable; the only effect of the frightful blow was to set him spinning, end over end, like the flying baton
of an acrobatic drum-major. As the spinning form crashed against the opposite wall of the room, Bradley floated in, carrying Clio's armor. Without a word the captain loosened the helpless girl's grip upon the bracket and encased her in the suit. Then, supporting her at the window, he held his Lewiston upon the captive's head while Costigan propelled him toward the opening. Both men knew that Roger's shield of force must be threatened every instant--that if he were allowed to release it he probably would bring to bear a hand-weapon even superior to their own.
Braced against the wall, Costigan sighted along Roger's body toward the most distant point of the lofty dome of the artificial planet and gave him a gentle push. Then, each grasping Clio by an arm, the two officers shoved mightily with their feet and the three armored forms darted away toward their only hope of escape--an emergency boat which could be launched through the shell of the great globe. To attempt to reach the Hyperion and to escape in one of her lifeboats would have been useless; they could not have forced the great gates of the main airlocks and no other exits existed. As they sailed onward through the air, Costigan keeping the
12
slowly-floating form of Roger enveloped in his beam, Clio began to recover.
"Suppose they get their gravity fixed?" she asked, apprehensively. "And they're raying us and shooting at us!"
"They may have fixed it already. They undoubtedly have spare parts and duplicate generators, but if they turn it on the fall will kill Roger too, and he wouldn't like that. They'll have to get him down with an airship, and they know that we'll get them as fast as they come up. They can't hurt us with hand-weapons, and before they can bring up any heavy stuff they'll be afraid to use it, because we'll be too close to their shell.
"I wish we could have brought Roger along," he continued, savagely, to Bradley. "But you were right, of course--it'd be altogether too much like a rabbit capturing a wildcat. My Lewiston's about done right now, and there can't be much left of yours--what he'd do to us would be a sin and a shame."
Now at the great wall, the two men heaved mightily upon a lever, the gate of the emergency port swung slowly open, and they entered the miniature cruiser of the void. Costigan, familiar with the mechanism of the craft from careful study from his prison
cell, manipulated the controls. Through gate after massive gate they went, until finally they were out in open space, shooting toward distant Tellus at the maximum acceleration of which their small craft was capable.
Costigan cut the other two phones out of circuit and spoke, his attention fixed upon some extremely distant point.
"Samms!" he called, sharply. "Costigan. We're out ... all right ... yes ... sure ... absolutely ... you tell 'em, Sammy; I've got company here."
Through the sound-disks of their helmets the girl and the captain had heard Costigan's share of the conversation. Bradley
