But there was no note on the refrigerator this evening, and he felt a prickle of something that hadn't yet quite had time to turn into worry. It was headed that way, though, and he slid onto one of the tall chairs at the kitchen dining bar while he looked around at the emptiness.
If anything had happened, she would've let you know, idiot, he told himself firmly. It's not like she didn't know exactly where you were!
He drew a deep breath, made himself sit back in the chair, and admitted to himself what was really worrying him.
Like a great many—indeed, the vast majority—of the alpha line pairings the Long-Range Planning Board arranged, Herlander and Harriet had been steered together because of the way their genomes complemented one another. Despite that, they'd had no children of their own yet. At fifty-seven, Herlander was still a very young man for a third-generation prolong recipient—especially one whose carefully improved body would probably have been good for at least a couple of centuries even without the artificial therapies. Harriet was a few T-years older than he was, but not enough to matter, and the two of them had been far too deeply buried in their careers to comfortably free up the amount of time required to properly rear children. They'd planned on having several biologicals of their own—all star line couples were encouraged to do that, in addition to the cloned pairings the Board produced—but they'd also planned on waiting several more years, at a minimum.
Although the LRPB obviously expected good things out of their children, no one had pushed them to accelerate their schedule. Valuable as their offspring would probably prove, especially with the LRBP's inevitable subtle improvements, it had been made pretty clear to them that the work both of them were engaged upon was of greater immediate value.
Which was why they'd been quite surprised when they were called in by Martina Fabre, one of the Board's senior members. Neither one of them had ever even met Fabre, and there'd been no explanation for the summons, so they'd felt more than a little trepidation when they reported for the appointment.
But Fabre had quickly made it clear they weren't in any sort of trouble. In fact, the silver-haired geneticist (who had to be at least a hundred and ten, standard, Simões had realized) had seemed gently but genuinely amused by their apparent apprehension.
"No, no!" she'd said with a chuckle. "I didn't call you in to ask where your first child is. Obviously, we do expect the two of you to procreate—that is why we paired you up, after all! But there's still time for you to make your contribution to the genome."
Simões had felt himself relaxing, but she'd shaken her head and wagged an index finger at him.
"Don't get too comfortable, Herlander," she'd warned him. "We may not be expecting you to procreate just yet, but that doesn't mean we don't have a little something we do want out of you."
"Yes, Ma'am," he'd replied, much more meekly than he usually spoke to people. Somehow, Fabre had made him feel like he was back in kindergarten.
"Actually," she'd let her chair come upright and leaned forward, folding her arms on her desk, her manner suddenly rather more serious, "we really do have a problem we think you two can help us with."
"A . . . problem, Doctor?" Harriet had asked when Fabre paused for a handful of seconds. She hadn't quite been able to keep a trace of lingering apprehension out of her voices, and Fabre had obviously noticed it.
"Yes." The geneticist had grimaced, then sighed. "As I say, neither of you were even remotely involved in creating it, but I'm hoping you may be able to help us out with solving it."
Harriet's expression had been puzzled, and Fabre had waved one hand in a reassuring gesture.
"I'm sure both of you are aware that the Board pursues a multi-pronged strategy. In addition to the standard pairings such as we arranged in your case, we also work with more . . . tightly directed lines, shall we say. In cases such as your own, we encourage variation, explore the possibilities for enhancement of randomly occurring traits and developments which might not occur to us when we model potential outcomes. In other cases, we know precisely what it is we're trying to accomplish, and we tend to do more in vitro fertilization and cloning on those lines."
She'd paused until both Simões had nodded in understanding. What Herlander had realized, although he wasn't certain Harriet had, was that quite a bit of that "directed" development had been carried out under cover of Manpower, Incorporated's slave breeding programs, which made the perfect cover for almost anything the LRPB might have been interested in exploring.
"For the past few decades, we seem to have been hitting a wall in one of our in vitro alpha lines," Fabre had continued. "We've identified the potential for what amounts to an intuitive mathematical genius, and we've been attempting to bring that potential into full realization. I realize both of you are extraordinarily gifted mathematicians in your own rights. For that matter, both of you test well up into the genius range in that area. The reason I mention this is that we believe the potential for this particular genome represents an intuitive mathematical ability which would be at least an order of magnitude greater than your own. Obviously, that kind of capability would be of enormous advantage to us if only because of its consequences for the sort of work I know you two are already engaged upon. Long-term, of course, the ability to inject it into the genetic pool as a reliably replicatable trait would be of even greater value to the maturation of the species as a whole."
Herlander had glanced at Harriet for a moment and seen the mirror of his own intensely interested expression on her face. Then they'd both looked back at Fabre.
"The problem in this case," the geneticist had continued, "is that all of our efforts to date have been . . . less than fully successful, shall we say. I'll go ahead and admit that we still don't have anything like the degree of understanding we wish we had where designed levels of intelligence are concerned, despite the degree of hubris some of my own colleagues seem to feel upon occasion. Still, we feel like we're on the right track in this instance. Unfortunately, our results to date fall into three categories.
"The most frequent result is a child of about average intelligence for one of our alpha lines, which is to say substantially brighter than the vast majority of normals or even the bulk of our other star lines. That's hardly a bad result, but it's obviously not the one we're looking for, because while the child may have an interest in mathematics, there's no sign of the capability we're actually trying to enhance. Or, if it's there at all, it's at best only partially realized."
"Less often, but more often than we'd like, the result is a child who's actually below the median line for our alpha lines. Many of them would be quite suitable for a gamma line, or for that matter for the general Mesan population, but they're not remotely of the caliber were looking for."
"And finally," her expression had turned somber, "we get a relatively small number of results where all early testing suggests the trait we're trying to bring out is present. It's in there, waiting. But there's an instability factor, as well."
"Instability?" It had been Herlander's turn to ask the question when Fabre paused this time, and the geneticist had nodded heavily.
"We lose them," she'd said simply. The Simões must have looked perplexed, because she'd grimaced again . . . less happily than before.
"They do fine for the first three or four T-years," she'd said. "But then, somewhere in the fifth year, we start to lose them to something like an extreme version of the condition which used to be called autism."
