Ambulance Ship sg-4

by James White

  “Doctor,” he added, “could you give me your hand, please?”

  Conway gave his hand to the Captain to steady him and help him to his feet while Fletcher carefully withdrew his other hand from the opening. Suddenly one of Fletcher’s foot magnets slipped along the deck. His arm jerked backwards instinctively to prevent him from falling, even though in the weightless condition he could not fall, sending the hand back inside the control area.

  “I touched something.” He sounded worried.

  “You certainly did,” said Conway, and pointed at the caged section of corridor.

  “Sir!” said Haslam on the suit frequency. “We are detecting strong intermittent vibrations throughout the fabric of the ship. Also metallic sounds!”

  Murchison came diving along the corridor from the airlock. She checked herself expertly against the wall. “What’s happening?” Then she, too, looked into the caged corridor. “What is happening?”

  For as far as they could see along the curvature of the corridor there was violent and noisy mechanical activity. The long metal bars projecting from their slots in the walls were whipping back and forth or up and down to the limits of their angles of travel, while the rods with their pointed or mace-like ends were jabbing up and down like pistons from the ceiling. Several of the bars and pistons were badly warped and were striking one another, which caused the awful din. As they watched, a small flap opened in the inboard wall of the corridor a few meters inside the grill, and a mass of something resembling thick porridge was extruded, to drift like a misshapen football into the path of the nearest wildly swinging bar.

  The material splattered in all directions, and the smaller pieces were batted about by the other bars and pistons until they moved about the corridor like a sticky hailstorm. Murchison captured some of it in a specimen bag.

  “Obviously a food dispenser of some kind,” she observed. “An analysis of this stuff will tell us a lot about the large one’s metabolism. But those bars and pistons are not, to my mind, a means of restraining the FSOJ. Not unless restraint includes clubbing it unconscious.”

  “With a physiological classification of FSOJ,” said Conway thoughtfully, “that might be the only way to do it, short of using a heavy-duty pressor beam.”

  “All the same,” Murchison went on, “I am feeling a slight attenuation of sympathy for the blind ones. That corridor looks more like a torture chamber than a cage.”

  Conway had been thinking the same thing and so, judging by his shocked and sickened expression, had the Captain. They had all been taught, and were themselves convinced, that there was no such thing as a completely evil and inimical intelligent race, and even the suggestion that they believed such a thing possible would have led to their dismissal from the Monitor Corps or from the Federation’s largest multienvironment hospital. Extraterrestrials were different, sometimes wildly and weirdly different, and during the early stages of contact a great deal of caution was necessary until a full understanding of their physiological, psychological and cultural background was available. But there was no such thing as an evil race. Evil or antisocial individuals, perhaps, but not an evil species.

  Any species that had evolved to the point of social and technological cooperation necessary for them to travel between the stars had to be civilized. This was the considered opinion of the Federation’s most advanced minds, which were housed inside some sixtyodd different life-forms. Conway had never been the slightest bit xenophobic, but neither was he completely convinced that somewhere there wasn’t an exception that would prove the rule.

  “I’m going back with the specimens now,” Murchison said. “I may be able to find some answers. The trouble is finding the right questions to ask.”

  Fletcher was stretched out on the deck again with one hand inside the control area. “I’ll have to shut off that … whatever it is. But I don’t know where exactly my hand was when I switched it on, or if I switched on anything else at the same time.” He tripped his suit radio toggle. “Haslam, Chen. Will you chart the extent of the noise and vibrations, please, and is there evidence of any other unusual activity within the ship?” He turned to Conway. “Doctor, while I’m trying to find the right button to push, would you do something for me? Use my cutting torch on the corridor wall midway between the L-bend here and the airlock—”

  He broke off as they were suddenly plunged into absolute darkness, which seemed to augment the clanging and metallic screeching sounds to such an extent that Conway fumbled for his helmet light switch in near panic. But before he could reach it the ship’s lighting came on again.

  “That wasn’t it,” said the Captain, then he continued: “The reason I want you to do this, Doctor, is to find an easier path to the survivors than the one along the corridor. You probably noticed that the majority of the cable runs originating in the control pods go inboard towards the power generation area of the ship, with very few leading out to the periphery. From this I assume that the area of the vessel outboard of the corridor cage and control center is the storage or cargo sections, which should, if the blind ones follow basic design philosophy where their spaceships are concerned, be comprised of large compartments connected by simple doors rather than pressurized bulkheads and airlocks. If this is so, and the sensor readings seem to confirm it, we should have to move only some cargo or stores out of the way to be able to bypass the control pods and get to the survivors fairly quickly. We would not have to risk running through that corridor, or worry about accidentally depressurlzing the ship by cutting in from topside …

  Before the Captain had finished speaking, Conway began cutting a narrow vertical rectangle in the wall plating, a shape that would enable both his eyes and the helmet light to be directed through the opening at the same time so that he could see into the adjoining compartment. But when he burned through the wall there was nothing to see except a black, powdery substance, which spilled out of the opening and hung in a weightless cloud until the movement of his cutter flame sent it spinning into tiny three-dimensional whirlpools.

  He worked his hand carefully into the hole, feeling the warmth of the still-hot edges through his thin gauntlets, and withdrew a small handful of the stuff to examine it more closely. Then he moved to another section of the wall and tried again. And again.

  Fletcher watched him but did not speak. All of the Captain’s attention was again concentrated in his fingertips. Conway began working on the opposite wall of the corridor, reducing the size of the test holes to speed up the process. When he had cut four widely separated fist-sized holes without uncovering anything but the powdery material, he called Murchison.

  “We are finding large quantities of a coarse black powder,” he told her, “which has a faint odor suggesting an organic or partly organic composition. It could be a form of nutrient soil. Does that fit the crew’s physiology profile?”

  “It fits,” said Murchison promptly. “From my preliminary examination of the two small cadavers I would say that the atmosphere in their ship is for the convenience of the larger FSOJ life-form. The blind ones do not possess lungs as such. They are burrowers who metabolize the organic constituents of their soil as well as any other plant or animal tissue that happens to be available. They ingest the soil via the large frontal mouth opening, but the larger upper lip is capable of being folded over the lower one so that the mouth is sealed shut when it needs to burrow without eating. We’ve noticed atrophy of the limbs, or to be more accurate, the movable pads on the underside that propel it, and of hypersensitivity in the uppersurface tactual sensors. This probably means that their culture has evolved to the stage where they inhabit artificially constructed tunnel systems with readily accessible food supplies, rather than having to burrow for it. The material you describe could be a special loosely packed nutrient soil that combines the ship’s food supply with a medium for physical exercise.”

  “I see,” said Conway.

  A blind, burrowing worm who somehow managed to reach the stars! Then Murchison’s next
words reminded him that the blind ones were capable of seemingly petty and cruel activities as well as those that were great and glorious.

  “Regarding the survivors,” she went on, “if the FSOJ laboratory animal, or whatever it is, is too close to the surviving crew-member and we cannot rescue both without endangering ourselves or the blind one, a large reduction in atmospheric pressure, provided it is carried out gradually so as to avoid decompression damage to the blind one’s tissues, would disable or more likely kill the FSOJ.”

  “That would be the last thing we would try,” said Conway firmly. The rules were very strict in first-contact situations like this, where one could never be absolutely sure that an apparently senseless and ferocious beast was, in fact, a non-sentient creature.

  “I know, I know,” Murchison replied. “And it will interest you to know that the FSOJ was in an advanced stage of pregnancy, a time during which most life-forms, regardless of their degree of intelligence, can feel overprotective, overemotional and overaggressive if they think their unborn is being threatened. That might be the reason why the FSOJ broke out of its cage. As well, the blind one would not have been able to kill it with its horn if the FSOJ’s underbody had not been locally weakened in preparation for the imminent birth.”

  Conway considered that for a moment. “The female FSOJ’s condition and the beating and prodding it had to take in the—”

  “I didn’t say it was female,” Murchison broke in, “though it may be. In many ways it is a far more interesting life-form than the blind one.

  “Save your mental energy for the one we know is intelligent,” Conway snapped at her. There was a moment’s silence, broken only by the background hiss from the suit radio. Then he apologized:

  “Ignore me, please, I’ve got a bad headache.”

  “Me, too,” Fletcher said. “I expect it is caused by the noise and subsonic effects of the vibration of all this moving machinery. If his headache is half as bad as mine you can forgive him, ma’am, and if you could have some helpful medication ready when we return to the ship—”

  “Make that three,” said Murchison. “My head has been aching since I came back here, and I was exposed to the noise and vibration for only a few minutes. And I’ve bad news for you: The headache does not respond to medication.”

  She broke contact. “Doesn’t it seem strange,” Fletcher asked worriedly, “that three people who breathed the air in this ship are suffering from—”

  “Back at the hospital,” Conway broke in, “they have a saying that psychosomatic aches are contagious and incurable. Murchison’s analyzer checked the ship’s atmosphere for toxic material, and any alien bugs present are just not interested in us. This particular headache could be a product of anxiety, tension, or a combination of various psychological factors. But because it is affecting all three of us at once, and all three of us have spent some time inside the ship, it is probable that the headache is being caused by some outside agency, very likely the noise and vibration from that corridor, and you were right the first time. I’m sorry I mentioned it.”

  “If you hadn’t,” said Fletcher, “I certainly would have done so. It is quite unpleasant and is affecting my ability to concentrate on these—”

  There was another interruption from the outer hull.

  “Haslam, sir. Chen and I have finished charting the extent of the sounds and vibration. They occupy a narrow band, perhaps two meters wide, which coincides with what you have called the corridor cage. The corridor runs right around the ship in a constant-radius circle, which is completed by the arc containing the control pods. But that’s not all, sir. The corridor intersects the area occupied by the two survivors.”

  Fletcher looked at Conway. “If I could only stop this mechanical torture chamber, or whatever it is, we might be able to squeeze through it to the survivors … But no, if it started up again when someone was inside, it would batter them to death. Very well,” he said to Haslam, “is there anything else to report?”

  “Well, sir,” Haslam replied hesitantly. “This may not mean anything, but we have headaches too.”

  For a long time there was silence while the Captain and Conway thought about the two Rhabwar officers’ headaches. The men had been outside the ship at all times, making contact with the hull plating infrequently and then only through their magnetic boots and gauntlets-both of which had padded and insulated interiors capable of damping out mechanical vibration. Besides, sounds did not travel through a vacuum. Conway could think of nothing that would explain the two men’s headaches, but not so the Captain.

  “Dodds,” Fletcher said suddenly to the officer he had left in the Rhabwar. “Run a sensor recheck for radiation emanating from this ship. It may not have been present until I started pushing buttons. Also, check for possibly harmful radiation associated with the nearby star cluster.”

  Conway gave a nod of approval, which the Captain did not see. Even flat on his back with a thumping headache making it difficult to think and with one arm disappearing into an alien control pod in which an unguarded touch could cause anything from the lights going out to an unscheduled Jump into hyperspace, Fletcher was doing all right. But the sensor reading, according to Dodds, cleared the alien ship and the space around them of any trace of harmful radiation. They were still thinking about this when the timid voice of Prilicla broke the silence.

  “Friend Conway,” called the empath, “I have delayed making this report until I was sure of my feelings, but there can no longer be any doubt. The condition of both survivors is improving steadily.”

  “Thank you, Prilicla,” said Conway. “That will give us more time to think of a way of rescuing them.” To Fletcher, he added, “But why the sudden improvement?”

  The Captain looked at the corridor cage and its outgrowth of furiously waving and jabbing metal and said “Could that have anything to do with it?”

  “I don’t know,” said Conway, grinning in relief because the chances of a successful rescue had increased. “Certainly the noise alone is fit to wake the nearly dead.”

  The Captain looked disapprovingly at him, plainly unable to see anything funny in the remark or the situation. Very seriously, he said, “I have checked and rechecked all of the flat rocker switches within reach. That particular form of actuator is the only kind suited to the short feeler pads possessed by the blind ones, because as manipulators the pads lack strength and leverage. But I have found something that feels like a lever, several inches long and terminating in a narrow reverse-conical handle. The cone is hollow and is probably designed to accommodate the tip of the blind one’s horn or sting. The lever is positioned at a forty-five-degree angle to its seating, which is the limit of its travel in the up direction. I intend moving it downwards.

  “In case something calamitous happens as a result, we should seal our helmets,” Fletcher added. He closed his helmet visor and replaced the gauntlet he had removed earlier. Then he reached inside the opening without hesitation, obviously knowing exactly where his hand was going.

  In the corridor cage all mechanical activity ceased abruptly. The silence was so complete that when someone scraped a magnetic boot against the outer hull the noise made Conway start. The Captain was smiling as he got to his feet and opened his visor again.

  “The survivors are at the other end of this corridor, Doctor,” he said, then added, “if we can just get to them.”

  But they found it completely impossible to wriggle through the thicket of projecting metal rods and bars. Even when the Captain took off his spacesuit to try it, he was successful only in collecting a number of cuts and abrasions. Disappointed, Fletcher climbed into his suit again and began attacking the metal projections with his cutter. But the metal was tough and required several seconds at maximum power before each metal bar was burned through. There were so many of the things it was like weeding a metal garden a stalk at a time, the Captain observed crossly. He had cleared less than two meters of the corridor cage when they were forced back to the airlock b
ecause of the buildup of heat.

  “It’s no good,” said the Captain. “We can cut a way through to them, but only in short stages with lengthy delays in between to allow the excess heat to dissipate by conduction through the fabric of the ship and to radiate into space. There is also the danger that the heat might melt the insulation on some of their power-control circuitry, with unknown results.”

  He tapped the wall beside him with his fist, so hard that it might almost have been a display of temper. “Emptying the storage spaces of nutrient soil would also be a long job, necessitating as it would the movement of the soil in installments from the storage spaces to the corridor to the lock and out, and we have no idea what structural problems could then arise inside those compartments. I’m beginning to think the only thing to do is cut a way in from outside. But there are problems there, too …

  Cutting down to the survivors through the double hull of the ship would generate a lot of heat, especially inside the portable lock they would have to use to guard against accidentally depressurizing the vessel. Once again, lengthy delays would be required to allow the heat to radiate away, although the process would be faster since they would already be on the outer hull. There was also the problem of cutting through the mechanical linkages to the bars and pistons projecting into the corridor, which would tend to generate a lot of heat inside the ship, heat which might have an adverse effect on the survivors. The only advantage was that they would not run the risk of being beaten to death by metal bars if as a result of their cutting operations the system switched itself on again.

  … And by the way, Doctor,” Fletcher added, changing from his lecturing tone, “my headache is fading.”

  Conway was telling him that his own headache was diminishing as well when Prilicla broke into the conversation. “Friend Fletcher, I have been monitoring emotional radiation of the survivors since you halted the corridor mechanisms. Their condition has deteriorated steadily since then, and they are now in the state similar to that detected on our arrival, or perhaps a little worse. Friend Fletcher, we could easily lose them.”
