"What?" said Docchi absently. Management details were unfamiliar to him and he was trying to pick them up as he went along. The scattered records were in order but some were still unaccounted for. "Oh. The deficiency biologicals. Good. How did you do it?" "I asked them." "And they knew? It's surprising. I'd expect them to be familiar with their standard treatment. But not something that's entirely new." Jeriann smiled faintly. "I'm not that good. I did find out what they used to get and then scrounged around in storage until I found supplies. If the old stuff kept them healthy once it should do so now." He hadn't thought of that, but then he wasn't accustomed to considering the same things a doctor would. Any trained person would know that sulfa hadn't been discarded with the discovery of penicillin, nor penicillin with the advent of the neo-biotics. Docchi studied her covertly; Jeriann was a competent woman, and an attractive one. "Of the remaining twenty we don't have biologicals for, I've determined we can make what eleven need." Only nine who were left out. It was a remarkable advance over a few days ago when there were forty-two. Nine for whom so far they could do nothing. It was queer how he worried about them more as the number diminished. Somehow it had greater significance now that he could remember each face distinctly. "And Maureen?" he inquired. Instinctively Jeriann touched the decorative belt that was so much more than what it seemed. "I'm afraid I misjudged her. I couldn't locate a thing for her." "You're sure she didn't destroy her prescription?" "I don't see what difference it makes as long as we don't have it," said Jeriann. "But yes, I'm sure. Once something is brought in it's simply not possible for a person as ignorant of the system as she is to track down and destroy every entry relating to it." "All right. I believe you." He glanced down at the list she'd given him. The actual figures weren't as optimistic as her report had been. "Wait. I notice you say here that out of twenty that we don't have supplies for that we can synthesize biologicals for eleven." She sat down. "That's what I said. How else can we get them? We've got the equipment. The asteroid never did depend on Earth for very many of our biologicals." He knew vaguely how the medical equipment functioned, rather like the commonplace food synthesizers. "We don't have anyone with experience." Jeriann shrugged. "I'm not a technician but I used to help out when there was nothing else to do. I expected to run it." The light flashed on his desk but Docchi ignored it. "Have you thought what an infinitesimal error means?" he asked. "Of course." He was struck by her calmness. "One atom hooked in the wrong place and instead of a substance the body must have it becomes a deadly poison. I've talked it over with the deficients. They agreed to it. This way they know they have a chance."
