“Captain. Conway,” he called suddenly. “Would you ask Lieutenant Chen, while he is searching the Tenelphi for the missing officer, to bring back samples of the ship’s air and food and liquid consumables? Would he also look for evidence of a leakage of toxic material, solid or gaseous, into the life-support system, and bring them, tightly sealed, to Pathologist Murchison for analysis as quickly as possible?”
“Will do,” Fletcher responded. “Chen, you overheard?”
“Yes, sir,” said the engineer officer. “I still can’t find the missing casualty, Doctor. Now I’m beginning to look in all the unlikely places.”
Because Conway’s helmet was still sealed, Murchison had been listening to the conversation on the Casualty Deck’s speaker as well as hearing his side of it through his suit’s external sound system. “Two questions, Doctor,” she said irritably. “Do you know what’s wrong with them, and has it anything to do with your using that overly loud suit speaker instead of opening your visor and talking normally?”
“I’m not sure,” said Conway.
“Perhaps,” she said angrily to Dodds, “he doesn’t like my perfume.”
Conway disregarded the sarcasm and looked around the ward. While he had been examining the casualty with Naydrad, Murchison and Dodds had stripped the others and were obviously waiting for instructions. Prilicla was already carrying out the instructions that Conway had yet to utter on the first two casualties, but then, Prilicla invariably said and did the right thing because it was an exceptionally fine doctor as well as an empath.
“If it wasn’t for the very high temperature and general severity of their symptoms,” Conway said finally, “I’d say we are dealing with a respiratory infection with associated nausea caused, perhaps, by swallowing infected mucus. But the sudden and incapacitating onset of the symptoms makes me doubtful of that diagnosis.
“But that is not the reason I stayed sealed,” he went on. “There was no reason for doing so at first. Now, however, I think it would be a good idea if Lieutenant Dodds and you sealed up. It may be an unnecessary precaution.”
“Or it may already be too late,” said Murchison, unclipping one of the lightweight helmets, which, with its connecting hose, air tank and body webbing, converted the coveralls she was wearing into a protective suit, proof against anything but the most corrosive atmospheres. Dodds had already sealed his visor with remarkable haste.
“Until we can get them to the hospital,” Conway said, “treatment must be supportive rather than curative. Replace the lost fluids intravenously, control the nausea and try to keep the temperature down. We may have to use body restraints to keep them from dislodging their monitor leads. Isolate them in pressure tents and raise the oxygen level. I think their condition is going to worsen, and we may eventually need to assist their breathing with a ventilator.”
He paused for a moment, and when he looked at Murchison he knew that the concern on his face was concealed by the blurring effect of his visor and by the suit’s external speaker, which distorted his voice.
“The isolation may be unnecessary,” he said. “These symptoms could just as easily be due to inhaling and swallowing an as yet unidentified toxin. We can’t be sure, and we haven’t the proper facilities to find the answer in the limited time available. As soon as we find out what happened to the missing crew-man, we’ll whisk them all back to Sector General and submit ourselves to a thorough-”
“While we are waiting,” Murchison broke in, her voice and features now also distorted by a helmet, “I would like to try to discover what it was that hit them, and what it is that may hit everyone else but yourself.”
“There may not be time for that,” Conway began, but the voice of the engineer officer reporting to the Captain made him break off.
“Captain, Chen here. I’ve found the duty roster, sir, and I’ve checked it against the IDs of the casualties. The missing man turns out to be Surgeon-Lieutenant Sutherland, so the Doctor’s guess was right. But his body is not here. I’ve searched thoroughly and he’s not inside the wreck. There are things missing as well-the ship’s portable sound and vision recorders, the crew’s personal recorders, cameras, baggage containers, all missing. Clothing and personal effects are drifting about inside the crew’s quarters as ~f they’d been scattered during a hurried unpacking.
