“We found a quick way out,” Conway said. “Well, relatively. Do you think you can climb with my assistance, or should I tie your arms and legs and lower you ahead of me?”
Sutherland was in poor shape, but he most emphatically did not want to be tied and lowered, no matter how carefully, down a tunnel whose walls were of twisted and jagged-edged metal. They compromised by strapping themselves together back to back, with Conway doing the climbing and the other medic fending them off the obstructions Conway could not see. They made very good time, so much so that they had begun to catch up to Prilicla before the Cinrusskin was more than halfway along the tunnel. Every time the sun shone into the other end, the dark circle that was the empath’s spacesuited body seemed larger.
The continuous hissing of the SOS signal grew louder by the minute, then suddenly it stopped.
A few minutes later the tiny black circle that was Prilicla became a shining disk as the empath cleared the mouth of the tunnel and moved into sunlight. It reported that the Rhabwar and the Tenelphi were in sight, and that there should be no problem making normal radio contact. They heard it calling the Rhabwar, and what seemed like ten years later came the hissing and crackling sound of the ambulance ship’s reply. Conway was able to make out some of the words through the background mush, so he was not completely surprised by Prilicla’s relayed message.
“Friend Conway,” said the empath, and he could imagine it trying desperately to find some way of softening the effect of its bad news. “That was Naydrad. All the DBDG Earth-humans on the ship, including Pathologist Murchison, are displaying symptoms similar to those of the Tenelphi officers, with varying degrees of incapacity. The Captain and Lieutenant Chen are the least badly affected so far, but both are in a condition that warrants their being confined to bed. Naydrad requires our assistance urgently, and the Captain says he’ll leave without us if we don’t hurry up. Lieutenant Chen is doubtful about our leaving at all, even if they weren’t having to modify the hyperdrive envelope to accommodate the Tenelphi. It seems there are additional problems caused by the proximity of the system’s sun that require a trained astrogator to—”
“That’s enough,” Conway broke in sharply. “Tell them to dump the Tenelphi! Decouple and undock and jettison any samples Chen took aboard for analysis. Neither Sector General nor the Monitor Corps will thank us for bringing back anything that has been in contact with the derelict. They might not be too happy to see us- He broke off as he heard Naydrad’s voice relaying his instructions to the Captain and the beginning of Fletcher’s reply. He went on quickly: “Prilicla, I’m receiving the ship direct, so I don’t need you as a relay anymore. Return to the ship as quickly as possible and help Naydrad with the patients. We should be clear of this tunnel in fifteen minutes. Captain Fletcher, can you hear me?”
A voice which Conway did not recognize as the Captain’s said, “I can hear you.”
“Right,” said Conway, and very briefly he explained what had happened to the Tenelphi and themselves …
Finding a derelict in the system they were surveying had been a welcome break in the monotony for the scoutship and for the offduty officers who went on board to investigate and, if possible, identify the vessel. Like all scoutships on survey duty, the Tenelphi had a complement consisting of a Captain and his astrogation, communications, engineering and medical officers, while the remaining five were the survey specialists, whose work went on around the clock.
According to Sutherland, the first officers to board the derelict had identified the ship very quickly, because of a lucky find of a store requisition form, dated and headed with the ship’s crest. The result had been that everyone, including the Captain, had hastily transshipped to the derelict. The sole exception was the ship’s medic, whose specialty was considered the least useful on what had suddenly become a mass information-gathering exercise.
For the derelict was none other than the Einstein, the first starship to leave Earth and the only one of those early generation ships from that planet not to be rescued by the later hyperdrive vessels. Many attempts at rescuing it had been made over the centuries, but the Einstein had not followed its intended course. It had been assumed that the ship had suffered a catastrophic malfunction within a relatively short time of leaving the solar system.
And now here it was, the first and undoubtedly the bravest attempt by mankind to reach the stars the hard way, because at that time its technology had been untried, because nobody knew with absolute certainty that its target system contained habitable planets, and because its crew, the very best people that Earth could produce, wanted to go anyway. As well, the Einstein was a piece of technological and psychosociological history, the embodiment of one of the greatest legends of star travel. Now this great ship with its priceless log and records was falling into the sun and would be destroyed within the week. Small wonder, therefore, that the Tenelphi was left with only its medical officer on board. But even he did not realize that there was any danger in the situation until the crew, sick and sweating and near delirium, began to return. From the onset Sutherland had discarded Conway’s first assumptions, that their condition was due to radiation poisoning, inhaling toxic material or eating infected food, because the returning officers told him about the conditions on board the derelict and how long some of the descendants of its crew had been able to survive.
Not only did the ship carry priceless records of man’s first attempt at interstellar flight, it also contained an unknown quantity and variety of bacteria-preserved by the heat and atmosphere and recently living human organisms-of a type which had existed seven hundred years ago and for which the human race no longer had immunity.
Noting the rapidly worsening condition of his fellow officers and knowing there was little he could do for them, Sutherland insisted that they all wear spacesuits continually to avoid the possibility of cross-infection-he could not be absolutely sure they were all suffering from the same disease-and as protection in case of accidents while they were moving clear of the derelict. Their intention was to Jump to Sector General, where some high-powered medical assistance would be available.
When the collision-the inevitable collision, according to Sutherland, considering the semi-conscious and delirious condition of the crew-occurred, he moved the men to the lock antechamber in preparation for a quick evacuation, tried to send a subspace radio signal, and not knowing if he was doing the job properly, tried to eject the distress beacon. But the collision had damaged the release mechanism, and he had to push it out of the airlock. His patients’ condition was worsening, and he wondered again if there was anything at all that he could do for them.
It was then that he decided to go aboard the derelict himself, to look for a cure in the very place the disease had originated. The solution might be in the derelict’s medicine chest, the “sin chest” of the garbled radio signal. With pressure dropping steadily aboard the badly damaged Tenelphi and all the recorders abandoned on the derelict, he could not leave a proper warning for any would-be rescuers. But he had done his best.
He had smeared the Tenelphi’s airlock outer seal with yellow grease, not knowing that the heat from the distress beacon would turn it brown, and he had marked his path through the derelict in similar fashion. Few people these days realized, and even Conway had been slow to remember, that in pre-space-travel times a ship with disease on board flew a yellow flag …
