Their single Tralthan passenger had completed its round-trip tour and left the ship on its home world, where two others, who as honeymooners were no longer single in either sense of the word, had come aboard. As yet they had shown no interest in otherspecies legends or in anything but each other apart from galloping ponderously up and down the sloping ramp on one side of the pool.
“Theoretically,” said O’Mara, “it is possible for two Earthhumans and a pair of overenthusiastic Tralthans to swim together, but…”
“We’d be mad in the head to try it” Joan finished for him. Laughing, she added, “Am I right in thinking that you dislike the water, Kledenth?”
“You’re wrong,” said the Kelgian, ruffling its fur. “I intensely hate, detest, and abhor the water. Let’s move over to the lounger beside the direct-vision panel. There’s nothing to see, but at least we’ll be out of range of the liquid fallout.”
They picked their way between the multi-species exercising and gaming equipment that filled the remainder of the recreation deck area. Apart from the swimmers, two Nidians playing something fast and complicated that involved knocking two tiny white balls between them, and a Melfan who was lying reading on something that resembled a surrealistic wastepaper basket, they had the place to themselves. Kledenth curled itself into a thick, furry S on a nearby mattress while Joan and O’Mara stretched out on loungers.
With nothing but grey hyperspace showing beyond the big direct-vision panel, they lay watching the two Tralthans charging in and out of the pooi and slapping at the water with their total of eight tentacles while making untranslatable noises to each other that sounded like hysterical foghorns. Every few seconds they were hidden by clouds of self-created spray.
“Extroverts,” said Kledenth.
Joan laughed suddenly and said, “Now, there is a life-form that really enjoys swimming?
“Not so” said O’Mara, watching them and trying not to allow the concern he was feeling from reaching his voice. “They love playing in water and they’re safe so long as their breathing orifices aren’t below the surface for more than a few minutes. But their body density is too great for them to be able to stay afloat even with the aid of maximum muscular effort. Those two are being very foolish.”
“Lieutenant O’Mara” she said, wriggling her slender body int8 a more comfortable position on the lounger in a way that immediately upped his blood pressure, “I bow to your superior knowledge of nonswimming Tralthans. But they can’t go on not swimming and expending energy at that rate for much longer, and then it will be our turn to make fools of ourselves… What the hell!”
Slowly their loungers were tipping sideways as if trying to roll their bodies onto the deck, which had developed a gentle slope in the same direction. Water spilled over the nearest edge of the pool and rolled in a six-inch tidal wave toward them, breaking against the deck supports of intervening equipment as it came. Suddenly the deck tilted in the opposite direction, and the miniature tidal wave gurgled to a stop and began flowing back into the pooi as the deck and their loungers became level again. The Tralthans were still creating so much turbulence that they apparently hadn’t noticed anything.
Again O’Mara felt the instant of vertigo characteristic of reemergence into normal space. He didn’t have to look at the directvision panel to know that it was again showing the stars and that, even though they had been traveling for only a short time in the hyperdimension, the Traltha system had been left far astern. A few seconds later the lounger padding pushed him gently into the air as they went weightless.
This was not a normal occurrence, he knew, particularly on a passenger vessel. Plainly Kreskhallar was having problems, perhaps serious ones. Joan was looking frightened and Kledenth’s fur was agitated.
“There’s nothing to worry about? he said, knowing that he was lying reassuringly to one Earth-person even though there was a Kelgian present who would accept it as the truth. “Is this your first experience of weightlessness? It looks as if the artificial gravity is on the blink, so just hold on to something solid until…
He broke off as the ship’s public-address system cleared its throat.
“This is your captain? it said. “Please remain calm. A minor malfunction has occurred in our artificial-gravity system. There is no danger to the ship and the period of weightlessness is a temporary inconvenience for which I can only apologize. Will all passengers currently occupying their cabins please remain in them until further notice. Those in other parts of the ship, particularly if they are in large, open areas such as the recreation deck, must return to their cabins as soon as possible. Anyone who lacks experience in weightless or low-G maneuvering should request assistance from a crew member, or from a fellow passenger with the necessary ability to assist you to your quarters…
He was aware of sideways motion, so gentle and gradual that he wasn’t surprised that the others hadn’t noticed it.
“As you will already have seen if you are close to a direct-vision port,” the captain continued, “we have returned to normal space, where we are able to apply lateral spin to the ship so that centrifugal force in the cabin areas inboard of the outer hull will replace the artificial gravity for the time necessary to repair the…
“You may take me to my cabin, Lieutenant O’Mara,” Joan broke in, holding onto her lounger with one hand and grabbing O’Mara’s wrist with the other. “The captain just made that an order?”
“No!” said O’Mara loudly, pulling his arm away and looking all around the big room for the nearest communicator. He spotted it about twenty meters away on the far side of the direct-vision panel. It had been years since he’d worked in gravity-free conditions, he thought as he grasped the sides of the lounger, drew his knees up until his feet were between his hands and prepared to make a weightless jump but it was an ability that one never forgot.
“Dammit,” said Joan, her face red with anger and embarrassment, “you didn’t have to be so bloody definite about it!”
“I was talking to that stupid captain, not you,’ O’Mara said angrily. He launched himself carefully in the direction of the communicator and continued speaking quickly as he moved. “Listen to me, carefully. You and Kledenth get out of here. Push off from the loungers, gently, and aim where you need to go or you’ll spin and lose orientation. Or do it in stages by pulling yourselves along or pushing against intervening fixed equipment to the nearest side wall and then around to the entrance. On no account take a shortcut across the deck or ceiling or go anywhere near the pool. Tell that Nidian and the two Melfans to do the same, and the Tralthans if you can make them hear you. Water is dangerous stuff in the weightless condition because it falls apart into… Just listen while I’m on the communicator, I don’t have time to explain twice.”
He landed neatly on his hands and knees beside the unit, steadied himself, and jabbed the attention button. The screen lit with the image of the ship’s crest and a cool, translated voice said that the call would be dealt with as soon as possible and to please wait. He looked around quickly.
Joan was relaying his instructions to the other passengers while trying to help Kledenth, but the public-address system and the Tralthans were making so much noise that her voice lacked the necessary volume and authority to get results. So far as he could see, nobody had moved from their original positions. He jabbed the button again.
The captain was saying,”… We will increase our spin until the centrifugal force inboard of the outer hull matches the gravity pull of one standard Earth G although, until the artificial-gravity system is returned, the outer cabin wall will be the floor. Once again we apologize for this temporary inconvenience. That is all.”
O’Mara swore again and this time he kept his thumb on the button. Behind him he could see the water slowly rising above the sides of the pooi and, its edges still held by the cohesion of surface tension, begin to roll down on them like a vast gob of clear syrup. Suddenly bulges and ripples caused by movements of the Tralthans appeared all over the slow-moving, transparent mass. Great, uneven lumps grew out of the surface like fat, shapeless arms that broke free and moved like monstrous, slow-moving amoebas toward the inner hull. The Tralthan noise was beginning to sound frightened, the flailing of their tentacles agitated rather than playful.
He noticed the other button then, the yellow one with the transparent cover and the warning sign, and swore again. This time it was at his own stupidity for not remembering that, on the older Melfan-built civilian vessels, yellow was the color denoting urgency rather than red. He flipped up the cover so hard that it came away in his hand and stabbed at the button as if it was a mortal enemy.
A boney, Melfan head appeared. The eyes stared at him for an instant; then an impatient, translated voice said, “Passengers are not allowed to use this channel unless there is.”
“An emergency, I know? he broke in. “O’Mara, Monitor Corps, on the recreation deck. Please connect me with your captain. I must speak to him, her, or it at once. Meanwhile, cancel the orJer to spin the ship. Do that now?”
“Sir, you have no operational authority on this civilian vessel? the other replied angrily. “And the captain is busy right now.”
“Then I’ll talk to one of the responsible ship’s officers? said O’Mara. “Presumably that means you?”
The exoskeletal features were incapable of changing color or registering emotion, but he could hear the Melfan’s pincers opening and closing with a sound like castanets. He moved to the side of the screen to give the other a clearer view of what was happening in the room, then continued speaking.
“The weightlessness and now the increasing spin are combining to empty the swimming pool? he said, forcing himself to speak slowly and clearly. “Unless the spin, and the buildup of centrifugal force, is checked right now, within a few minutes, at the present rate of descent, many tons of water will fall against the inner hull. The hull structure will take it, but can the seals of the direct-vision panel?”
“The seals can take it,” said the Melfan, and added, “Well, probably.”
“With the falling water? O’Mara went on, “will be the weight of two adult Tralthan swimmers. Can they take that, too?”
“Negative? said the officer, swiveling its head to look offscreen. “Captain! Emergency Blue Three. Risk of imminent hull breach on the rec deck. I’m putting the image on your repeater screen. Kill the spin and return to weightless conditions, now!”
“No? said O’Mara sharply. “We need a little weight here, no more than one-eighth G, to allow the water to stabilize so we can rescue the swimmers and nonaquatics. Weightless it will be scattered in liquid lumps all over the place with no stable surface to swim to. In those conditions people can panic and drown.”
He stopped as the Melfan’s face was replaced by the hairy, Orligian features of the captain.
“Understood, Lieutenant? it growled through its translator. “No more thap one-eighth G. You’ve got it. I’m sending the ship’s medic, Dr. Sennelt, to you. It’s all I can spare right now. Keep this vision channel open so’s we can see what’s happening…?”
Before the other had finished speaking, O’Mara had launched himself toward the tangled bodies of Joan and Kledenth.
The Kelgian was trying to wrap itself around Joan, who was trying desperately to push both of them sideways to escape the slowly falling mass of water that was now only a few meters above them. But neither of them were in contact with anything solid, so they were just rotating untidily around their common center of gravity. O’Mara landed on the nearest lounger, wrapped his lower legs around it, grabbed Joan firmly by the wrists, and pulled her free. Then he transferred his gfip to her upper arms.
“Listen to me? he said urgently. “There’s no time to get both of you to the side wall. You’ve got to jump straight up, as hard as you can, in a vertical dive through the water.” He glanced upward at the struggling, shadowy bodies of the Tralthans and added, “No, angle your dive to the right or you’ll hit those two. Dive fast and cleanly, like you always do. You might hit turbulence, air pockets, places where there’s nothing but bubbles that you can’t see through. Keep going, don’t stop to breathe or you could disorientate and drown, until your momentum takes you through to clear air and beyond to the entrance wall. Did you understand that? Now, hyperventilate for a few seconds, then go!”
She nodded and swore, still struggling to pull free of the panicking Kledenth. O’Mara knew exactly where to grab a male Kelgian to make it let go. He gripped her by the upper thighs, steadied her feet against the deck, and said, “Don’t worry, I’ll take care of Kledenth. Go!”
O’Mara wrapped both arms around the Kelgian’s middle, looked up quickly then sideways toward the wall. The lower surface of the water was rippling and growing enormous blisters that bulged downward less than two meters and about ten seconds distant in space and time. They might just make it to the side wall before the watery mass landed on them. Kledenth saw it, too, and began making high-pitched, terrified sounds. Just as he was about to kick away from the lounger framework on a path that would take them laterally along the deck, it tried to wriggle out of his arms.
“You’ll be all right? he said. “Hold still, dammit!”
But instead of holding still, Kledenth’s body went into a panic convulsion and suddenly O’Mara’s face was buried in rippling fur. One foot slipped from the lounger frame just as he jumped. Instead of flying toward the side wall they spun together into the deck. He had barely time to fill his lungs before the water was all around them.
Through the fog of air bubbles escaping from Kledenth’s fur he saw the dark, indistinct shape of one of the Tralthans falling slowly down on them. Desperately he felt around with his free hand in the opaque turbulence for the lounger frame, found it, and, bending at the knees and changing to a two-handed grip on the Kelgian’s frantically wriggling body, he planted his feet against the frame and prepared to kick out hard. But too late.
The Tralthan’s massive body landed on them, pinning O’Mara’s feet and the Kledenth’s lower body to the deck. There was a sudden, bright explosion of bubbles as the sudden pressure from the Tralthan’s body pushed all the air out of the Kelgian’s lungs. He fought the instinctive urge to grasp with the pain in his feet and fought instead to keep as much air as possible in his own lungs.
He was going to need it.
