Alien Emergencies - James White [181]
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 remarkably accurate.”
When Conway entered Control a few minutes 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
