It was Murchison who asked the obvious question. “For not seeing how that endplate opened,” Fletcher replied. He made several more self-derogatory remarks in an undertone, then went on, “It drops out, or there is probably a spring-loaded actuator which pushes it out through the slot which you can see behind the coupling collar. No doubt there is an internal air pressure sensor linked to the actuator to keep the endplate from popping out accidentally when the section is in space or the adjoining section is airless. Do you intend returning with this section and not just the cadaver?”
The tone of the question suggested that if such was not the Doctor’s intention, then forceful arguments would be forthcoming to make him change his mind.
“As quickly as possible,” Conway said dryly. “Pathologist Murchison is just as keen to look inside that alien as you are to look inside its ship. Please ask Naydrad to stand by the Casualty Lock.”
“Will do,” Fletcher said. He paused for a moment, then went on seriously, “You realize, Doctor, that the manner in which these cylinders open means that their occupants were sealed into their suspended animation compartments while in atmosphere, almost certainly on their home planet, and the cylinders were not meant to be opened until their arrival on the target world. These people are members of a-sublight colonization attempt.”
“Yes,” Conway said absently. He was thinking about the probable reaction of the hospital to receiving a bunch of outsize, hibernating e-ts who were not, strictly speaking, patients but the survivors of a failed colonization flight. Sector General was a hospital, not a refugee camp. It would insist, and rightly, that the colonists be transferred either to their planet of origin or destination. Since the surviving colonists were in no immediate danger there might be no need to involve the hospital at all — or the ambulance ship — except in an advisory capacity. He added, “We are going to need more help.”
“Yes,” Fletcher said with great feeling. It was obvious that his thinking had been parallelling Conway’s. “Rhabwar out.”
By the time Tyrell had returned to the assembly area, it was beginning to look congested. Twenty-eight hibernation compartments — all of which, according to Prilicla, contained living e-ts — hung in the darkness like a gigantic, three-dimensional picture showing the agglutinization of a strain of rod-shaped bacilli. Each section had been numbered for later identification and examination. There were no other scoutships in the area because they were busy retrieving more cylinders.
Even with the Casualty Deck’s artificial gravity switched off and tractor beams aiding the transfer, it took Murchison, Naydrad, and Conway more than an hour to extricate the cadaver from its wrecked compartment and bring it into Rhabwar.Once inside it flowed over the examination table on each side and on to intrument trolleys, beds, and whatever else could be found around the room to support its massive, coiling body.
Fletcher paid them a visit some hours later to see the cadaver at close range, but he had chosen a moment when Murchison’s investigation was moving from the visual examination to the dissection stage and his stay was brief. As he was leaving he said, “When you can be spared here, Doctor, would you mind coming upto Control?”
Conway nodded without looking up from his scanner examination of one of the alien’s breathing orifices and its tracheal connection. The Captain had left when he straightened up a few minutes later and said, “I just can’t make head or tail of this thing.”
“That is understandable, Doctor,” Naydrad said, who belonged to a very literal-minded species. “The being appears to have neither.”
Murchison looked up from her microscopic examination of a length of nerve ganglia and rubbed her eyes. She said, “Naydrad is quite right. Both head and tail sections are absent and may have been surgically removed, although I cannot be certain of that even though there are indications of minor surgery having taken place at one extremity. All that we know for sure is that it is a warm-blooded oxygen breather and probably an adult. I say 'probably' despite the fact that the creature in the first cylinder was relatively more massive. Genetic factors generally make for size differences among the adults of most species, so I cannot assume that it is an adolescent or younger. Of one thing I am sure — Thornnastor is going to enjoy itself with this one.”
“So are you,” Conway said.
She smiled tiredly and went on, “I don’t wish to give the impression that you are not helping, Doctor. You are. But I had the distinct feeling back there that the Captain was just being polite, and he wants to see you very urgently.”
Prilicla, who had been resting on the ceiling between trips outside to monitor the emotional radiation of newly arrived survivors, made trilling and clicking noises which translated as “For a nonempath, friend Murchison, your feeling was re^ markably accurate.”
When Conway entered Control a few mintues later, both captains were present and they looked relieved to see him. It was Nelson who spoke first.
“Doctor,” he said quickly, “I think this rescue mission is getting out of hand. So far thirty-eight contacts have been made and the sensors report the presence of life on all but two of them, and more cylinders are being reported every few minutes. They are all uniform in size and the present indications are that there are many more sections out there than would be necessary to complete one Wheel.”
“If, for technical or physiological reasons, the alien vessel had to have the configuration of a Wheel,” Conway said thoughtfully, “then it could have been built, as were some of our early space stations, in a series of concentric circles, as wheels within wheels.”
Nelson shook his head. “The longitudinal curvature on all sections is identical. Could there have been two Wheels, separate but identical vessels, which were in collision?”
“I disagree with the collision theory,” Fletcher said, joining in for the first time. “At least between two or more Wheels. There are far too many survivors and undamaged sections for that. Their vessel seems to have fallen apart. I think there was a high-velocity collision with a natural body, the shock of which shook the hub and central support structure apart.”
Conway was trying to visualize the finished shape of this alien jigsaw puzzle. He said, “But you still think there was more than one Wheel?”
“Not exactly,” Fletcher replied. “Two of them mounted side by side, with a different alien or set of aliens in each. Right now we don’t know whether we are retrieving single aliens who have been surgically modified for travel or pieces of much larger creatures, and we won’t know how many we are dealing with until the scoutships begin bringing back heads and tails. I’m assuming that all of the occupants were in suspended animation and their ship ran itself, accelerating or decelerating along its vertical axis. If I’m right then the hub wreckage should contain the remains of just one propulsion unit and one section which contained the automatic navigation and sensor equipment.”
Conway nodded. “A neat theory, Captain. Is it possible to prove it?”
Fletcher smiled and said, “All of the pieces are out there, even though some of them will be smashed into their component parts and difficult to identify, but given time and the necessary assistance we could fit them together.”
“You mean reconstruct it?”
“Perhaps,” Fletcher replied in an oddly neutral tone. “But is it really any of our business?”
Conway opened his mouth, intending to tell the other exactly what he thought of a damn fool question like that, then closed it again when he saw the expressions on both captains’ faces.
For the truth was that the situation which was developing here was no longer any of their business. Rhabwar was an ambulance ship, designed and provisioned for short-duration missions aimed at the rescue, emergency treatment, and transfer to the hospital of survivors of accident or disease in space. But these survivors did not require treatment or fast transport to the hospital. They had been in suspended animation for a long time and would be capable of remaining in that condition without harm for a long time to come. Reviving them and, more important, relocating them on a suitable planet would be a major project.
The sensible thing for Conway to do would be to bow out gracefully and dump the problem in the laps of the cultural contact specialists. Rhabwar could then return to its dock and the medical team could go back to treating the weird and wonderful variety of patients who turned up at Sector General while they waited for the next distress call for their special ambulance ship.
But the two men watching him so intently were a scoutship commander on survey duty, who would be lucky if he turned up one inhabited system in ten years of searching, and Major Fletcher, Rhabwar’s Captain and a recognized authority in the field of extraterrestrial comparative technology — and the rescue of this e-t sublight
