Forty-four Eleven 68th Street.
Ruth caught her breath, unable to hide her elation. His good eye never left her face, though, clear and aware and so very weary. She hadn’t tricked him. He had chosen to give up his secret, after first impressing her again with his skill set.
It was not surrender but a change of strategy. He jabbered for another ten minutes, his cadence rushed, desperate to explain himself as his body failed him. Fatigue reduced his mumble to a slur and he soon became unable to follow his own thoughts. He repeated himself, slapping his hand on his leg, closing his eyes or staring at her with uneven, fading intensity.
Sawyer had one more surprise for them.
24
Kendra Freedman expected to live forever — two or three hundred years, at least. Destroying cancerous cells was only the beginning. The archos nanotech had the capacity to rid the body of all disease and pollutants. The potential existed to overcome age itself, scouring away plaques and fatty deposits, rebuilding bones depleted by osteoporosis, replenishing the tissues of the heart, liver, stomach.
Their parents’ generation might be the last to die.
Given two hundred years of good health in which to continue their work — and to allow other medical technologies to advance — they could become true immortals.
Four years before the plague, Al Sawyer jumped at the chance to work with Freedman. It wasn’t that he bought into her immortality rap. The field was full of enthusiastic kooks proposing everything from heads-up computers mounted inside the optic nerve to cold fusion in a Coke bottle. He joined Freedman because she was independent and because she offered him all the latitude he wanted and because she had money.
Nearly two decades of sky-high promises followed by more realistic, incremental advances in nanotech had dried up venture capital funding as investors grew disillusioned, but Freedman had a sugar daddy, a rich man who didn’t want to take it with him.
She offered Sawyer a six-figure salary and at least rented time on any equipment he wanted. It was a sweet deal, maybe too sweet for a freshly minted Ph.D., and Sawyer soon found out why. His contract was strict on intellectual rights. He would own anything he designed, but Freedman would always have free license — and in the meantime he was forbidden from publishing. Sawyer didn’t care. If he’d wanted to be famous he would have learned to play the guitar.
Freedman was a genius engineer and didn’t need help building her device. She hired Sawyer to teach her baby to multiply. His thesis had been on replication algorithms, like those of so many of his contemporaries. Flawless self-assembly was the last great hurdle in nanotech, and there were hundreds of hotshots around the world filing for patents on every marginal improvement and new theory. Soon somebody would take that breakthrough step and leave everyone else buying the rights, shaking their heads for the rest of their lives and mumbling about how close they’d been. He didn’t want to be one of the losers.
A black woman in a white man’s world, Kendra Freedman actually had a few more chips on her shoulder than Sawyer did himself. It was a starting point, something in common, and fostered an us-against-them attitude that was its own motivation. She was already working sixty-hour weeks before he came along, and an unspoken competition kept them both in the lab for seventy or eighty or more as they pushed on through nights and weekends. The man-woman thing played little part in their relationship. They were both too tired and anyway Freedman was five-foot-two and 170 pounds, shaped like a pear. That was surely some part of her drive to create body-adjusting nanos.
At the time they were located on the outskirts of Stockton, because she had family nearby and because she was saving serious cash on her lease. Freedman had seen too many competitors burn through their funding and suddenly end up on the auction block.
Everything changed when Sawyer ran his first successful computer simulation, three short years after signing on. Her backer was becoming impatient — the man was sixty-two— and while Freedman had continually improved the components of her device, not enough progress had been made on its programming, in part because they had a limited number of prototypes available for trials. She pulled everyone from their specialties to support Sawyer’s work, including herself.
His script was initially error-prone but always quick. It was also the forward leap that Freedman needed to renew her backer’s interest. He brought in old friends, new funding, and Freedman blew tens of millions upgrading her computers and fabrication gear. Yet even as this equipment was delivered, her backer insisted on uprooting them. His new partnership had secured superior lab space in Sacramento, not far from the university, as well as a loose affiliation with the school that would allow Freedman to take advantage of computer science grad students. Moving her into a major city would also make it easier to bring other potential investors on walk-throughs.
The new lab included a new isolation system, a hermetic chamber large enough to encompass their working lab. Sawyer’s replication script had a “start” but no “stop,” and in fact they hoped not to encumber his program with an end command. Ideally a well-integrated archos would devour all cancerous cells, and only cancerous cells, and therefore quit replicating when the diseased tissue was gone. For the moment, however, their half-finished nano appeared able to multiply endlessly, which was both marvelous and frightening.
Freedman was prudent. She’d built the hypobaric fuse into the heart of her device early on, and as a safeguard it was foolproof. Test series would be run inside atmosphere hoods inside the larger chamber, for double insurance. It was unlikely that archos could escape the hoods, but the pressure within the hermetic chamber was maintained below self-destruct and the only way in and out was through an air lock.
She chose two-thirds of a standard atmosphere as her trigger because it was a significant drop yet still tolerable for test animals and people. For simplicity she debated rounding down from 66.6 percent to 65, but her frugal habits led her to settle on 70 percent instead, since it would take slightly less time to cycle the air lock to that level. Every month they’d save themselves a few hours, and save on her electric bill.
There were larger dangers, so-called acts of God— earthquake, fire, flood — but they set their atmosphere hoods to purge at the first hint of any threat to containment.
It was the head of their software team who brought archos into the world, a man named Andrew Dutchess.
* * * *
At fifty, Dutchess was the oldest member of their group, a onetime refugee from the tech stock collapse of the late 1990s. He had been chief operating officer of a major corporate branch advancing new methods of screening for prostate cancer. He had been a paper millionaire and rich in family as well, married and the father of a boy and a girl.
The recession and his company’s failure could not be blamed entirely for his divorce — like all of them he worked too many hours — just as no one else could be held responsible years later for his decision to steal archos. But Dutchess had never experienced Sawyer’s success. Dutchess had been under increased strain as Freedman pushed him to meet expectations.
Too late, ravenous and cold on the desolate rock island above Bear Summit, Sawyer decided that Dutchess probably didn’t really do it for the money.

Dutchess wedged a desk chair between the outer doors of the air lock, and the inner doors could not be opened until the lock equalized. Freedman and Sawyer were still inside. There was no mistaking what Dutchess had done but neither of them understood at first, rapping on the three-inch glass and shouting.
