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…
“Sutherland discovered that the medication in the Einstein’s sick bay had long since spoiled,” Conway went on, “but he did find a medical textbook which mentioned a number of diseases with symptoms similar to those shown by our people. It is one of the old influenza variants, he thinks, although in our case the loss of natural immunity over the centuries means that these symptoms are being experienced with much greater severity, and any prognosis would be uncertain. That is why I would like you to record this information for proper subspace transmission to Sector General, so that they will know exactly what to expect. And I suggest you make preparations for an automatic Jump, in case you aren’t feeling well enough to-”
“Doctor,” the Captain replied weakly, “I’m trying to do just that. How quickly can you get back here?”
Conway remained silent for a moment while he and Sutherland cleared the edge of the tunnel. “I have you in sight. Ten minutes.”
Fifteen minutes later Conway was removing Sutherland’s spacesuit and uniform on the Casualty Deck, which was rapidly becoming overcrowded. Doctor Prilicla was hovering over the patients in turn, keeping an eye and an empathic faculty on their condition, while Naydrad brought in Lieutenant Haslam, who had collapsed at his position in Control a few minutes earlier.
Neither of the extraterrestrials had anything to fear from terrestrial pathogens, even seven-hundred-year-old pathogens. The Tenelphi and Rhabwar crew-members and Murchison could only lie and hope, if they weren’t already delirious or unconscious, that their bodies’ defenses would find some way of fighting this enemy from the past. Only Conway had remained free from infection, because a smear of grease or something in a garbled radio signal had worried his subconscious to the extent that he had not unsealed his visor after the scoutship’s officers had been brought aboard.
“Four-G thrust in five seconds,” came Chen’s voice from the speaker. “Artificial gravity compensators ready.”
The next time Conway looked at the repeater screen it showed the Einstein and the Tenelphi shrunk to the size of a tiny double star. He finished making Sutherland as comfortable as possible, checked his IVs and moved on to Haslam and Dodds. He was leaving Murchison to the last, because he wanted to spend more time with her.
