"Then what do we do?"
Words again issued from between Evans's pale, cold lips: "Back to the city. Quickly!"
Lucky, motionless, eyes fixed on the unwavering muzzle of his friend's blaster, spoke softly and quickly to Bigman.
Bigman acknowledged the words by the slightest of nods.
The Hilda moved back along the path it had come, back toward the city.
Lou Evans, councilman, stood against the wall, white-faced and stern, his pitiless eyes shifting from Lucky to Bigman to the controls. His body, frozen into utter obedience to those who controlled his mind, did not even feel the need of shifting the blaster from one hand to the other.
Lucky strained his ears to hear the low sound of Aphrodite's carrier beam as it sounded steadily on the Hilda's direction finder. The beam radiated in all directions on a definite wave length from the topmost point of Aphrodite's dome. The route back to the city became as obvious as though Aphrodite were in plain sight and a hundred feet away.
Lucky could tell by the exact pitch of the beam's low whine that they were not approaching the city directly. It was a small difference indeed, and one that was not at all obvious to the ear. To Evans's controlled ears, it might pass unnoticed. Fervently, Lucky hoped so.
Lucky tried to follow Evans's blank glare when his eyes rested on the controls. He was certain that it was the depth indicator that those eyes rested upon. It was a large dial, a simple one that measured the water pressure. At the distance Evans stood it was simple enough to tell that the Hilda was not nosing surfaceward.
Lucky felt certain that, should the depth-indicator needle vary in the wrong direction, Evans would blast without a moment's hesitation.
Try as he might to think as little as possible about the situation, to allow as few specific thoughts as possible to be picked up by the waiting V-frogs, he could not help but wonder why Evans did not shoot them out of hand. They had been marked for death under the giant patch, but now they were only being herded back to Aphrodite.
Or would Evans shoot them down just as soon as the V-frogs could overcome some last scruple in the captive's subjected mind?
The carrier beam moved a little further off pitch. Again Lucky's eyes flickered quickly in Evans's direction. Was he imagining it, or did a spark of something (not emotion, exactly, but something) show in Evans's eyes?
A split second later it was obviously more than imagination, for there was a definite tightening of Evans's biceps, a small lifting of his arm.
He was going to shoot!
And even as the thought passed quickly through Lucky's mind and his muscles tensed involuntarily and uselessly for the coming of the blast, the ship crashed. Evans, caught unaware, toppled backward. The blaster slithered from his sprawling fingers.
Lucky acted instantly. The same shock that threw Evans back threw him forward. He rode that shock and came down upon the other, clutching for his wrist and seizing it with steely fingers.
But Evans was anything but a pigmy, and he fought with the unearthly rage that was imposed upon him. He doubled his knees above him, caught Lucky in the thighs, and heaved. The still rocking ship fortuitously added its roll to the force of Evans's thrust and the captive councilman was on top.
Evans's fist pounded, but Lucky's shoulder fended the blow. He raised his own knees and caught Evans in an iron scissors hold just below the hips.
Evans's face distorted with pain. He twisted, but Lucky writhed with him and was on top once more. He sat up, his legs maintaining their hold, increasing it.
Lucky said, "I don't know if you can hear or under stand me, Lou…"
Evans paid no regard. With one last contortion of his body, he flung himself and Lucky into the air, breaking Lucky's hold.
Lucky rolled as he hit the floor and came lithely to his feet. He caught Evans's arm as the latter rose and swung it over his shoulder. A heave and Evans came crashing down on his back. He lay still.
"Bigman!" said Lucky, breathing quickly and brushing back his hair with a quick motion of his hand.
"Here I am," said the little fellow, grinning and swinging Turner's blaster lightly. "I was all set, just in case."
"All right. Put that blaster away, Bigman, and look Lou over. Make sure there are no bones broken. Then tie him up."
Lucky was at the controls now, and with infinite caution he backed the Hilda off the remnants of the carcass of the giant patch he had killed hours before.
Lucky's gamble had worked. He had hoped that the V-frogs with their preoccupation with mentalities would have no real conception of the physical size of the patch, that with their lack of experience of subsea travel, they would not realize the significance of the slight off-course route Bigman had taken. The whole gamble had been in the quick phrase which Lucky had spoken to Bigman as the latter had turned the ship back to the city under the threat of Evans's blaster.
"Afoul of the patch," he had said.
Again the Hilda's course changed. Its nose lifted upward.
Evans, bound to his bunk, stared with weary shame-facedness at Lucky. "Sorry."
"We understand, Lou. Don't brood about it," said Lucky lightly. "But we can't let you go for a while. You see that, don't you?"
"Sure. Space, put more knots 6n me. I deserve it. Believe me, Lucky, most of it I don't even remember."
"Look, you better get some sleep, fella," and Lucky's fist punched Evans lightly hi the shoulder. "We'll wake you when we hit surface, if we have to."
To Bigman, a few minutes later, he said quietly, "Round up every blaster on the ship, Bigman, every weapon of every sort. Look through stores, the bunk lockers, everywhere."
"What are you going to do?"
"Dump them," said Lucky succinctly.
"What?"
"You heard me. You might go under. Or I might. If we do, I don't want anything with which we can expect a repetition of what has just happened. Against the V-frogs, physical weapons are useless, anyway."
One by one, two blasters, plus the electric whips from each sea suit, passed through the trash ejector. The ejector's hinged opening stood flush with the wall just next to the first-aid cupboard, and through it the weapons were puffed through one-way valves into the sea. "It makes me feel naked," muttered Bigman, staring out through the port as though to catch sight of the vanished weapons. A dim phosphorescent streak flashed across, marking the passing of an arrow fish. That was all.
The water pressure needle dropped slowly. They had been twenty-eight hundred feet under to begin with. They were less than two thousand now.
Bigman continued peering intently out the port. Lucky glanced at him. "What are you looking for?" "I thought," said Bigman, "it would get lighter as we got up toward the top."
"I doubt it," said Lucky. "The seaweed blankets the surface tightly. It will stay black till we break through." "Think we might meet up with a trawler, Lucky?" "I hope not."
They were fifteen hundred feet under now. Bigman said with an effort at lightness, a visible attempt to change the current of his own thoughts, "Say, Lucky, how come there's so much carbon dioxide in the air on Venus? I mean, with all these plants? Plants are supposed to turn carbon dioxide into oxygen, aren't they?"
"On Earth they are. However, if I remember my course in xenobotany, Venusian plant life has a trick all its own. Earth plants liberate their oxygen into the air; Venusian plants store theirs as high-oxygen compounds in their tissues." He talked absently as though he himself was also using speech as a guard against too-deep thinking. "That's why no Venusian animal breathes. They get all the oxygen they need in their food."
"What do you know?" said Bigman in astonishment.
"In fact, their food probably has too much oxygen for them, or they wouldn't be so fond of low-oxygen food, like the axle grease you fed the V-frog. At least, that's my theory."
