Dr. X's real name was a sequence of shushing noises, disembodied metallic buzzes, unearthly quasi-Germanic vowels, and half-swallowed R's, invariably mangled by Westerners. Possibly for political reasons, he preferred not to pick a fake Western name like many Asians, instead suggesting, in a vaguely patronizing way, that they should just be satisfied with calling him Dr. X– that letter being the first in the Pinyin spelling of his name.
Dr. X placed the diamond slide into a stainless-steel cylinder. At one end was a teflon-gasketed flange riddled with bolt-holes. Dr. X handed it to one of his assistants, who carried it with both hands, as if it were a golden egg on a silken pillow, and mated it with another flange on a network of massive stainless-steel plumbing that covered most of two tabletops. The assistant's assistant got the job of inserting all the shiny bolts and torque-wrenching them down.
Then the assistant flicked a switch, and an old-fashioned vacuum pump whacked into life, making conversation impossible for a minute or two. During this time Hackworth looked around Dr. X's laboratory, trying to peg the century and in some cases even the dynasty of each item. A row of mason jars stood on a high shelf, filled with what looked like giblets floating in urine. Hackworth supposed that they were the gall bladders of now-extinct species, no doubt accruing value by the moment, better than any mutual fund. A locked gun cabinet and a primeval Macintosh desktop-publishing system, green with age, attested to the owner's previous forays into officially discouraged realms of behavior. A window had been cut into one wall, betraying an airshaft no larger than a grave, from the bottom of which grew a gnarled maple. Other than that, the room was packed with so many small, numerous, brown, wrinkled, and organic-looking objects that Hackworth's eyes lost the ability to distinguish one from the next. There were also some samples of calligraphy dangling here and there, probably snatches of poetry.
Hackworth had made efforts to learn a few Chinese characters and to acquaint himself with some basics of their intellectual system, but in general, he liked his transcendence out in plain sight where he could keep an eye on it– say, in a nice stained-glass window– not woven through the fabric of life like gold threads through a brocade.
Everyone in the room could tell by its sound when the mechanical pump was finished with its leg of the relay. The vapor pressure of its own oil had been reached. The assistant closed a valve that isolated it from the rest of the system, and then they switched over to the nanopumps, which made no noise at all. They were turbines, just like the ones in jet engines but very small and lots of them. Casting a critical eye over Dr. X's vacuum plumbing, Hackworth could see that they also had a scavenger, which was a cylinder about the size of a child's head, wrinkled up on the inside into a preposterous surface area coated with nanodevices good at latching onto stray molecules. Between the nanopumps and the scavenger, the vacuum rapidly dropped to what you might expect to see halfway between the Milky Way and Andromeda galaxies. Then Dr. X himself quivered up out of his chair and began shuffling around the room, powering up a gallimaufry of contraband technology.
This equipment came from diverse technological epochs and had been smuggled into this, the Outer Kingdom, from a variety of sources, but all of it contributed to the same purpose: It surveyed the microscopic world through X-ray diffraction, electron microscopy, and direct nanoscale probing, and synthesized all of the resulting information into a single three-dimensional view. If Hackworth had been doing this at work, he would already be finished, but Dr. X's system was a sort of Polish democracy requiring full consent of all participants, elicited one subsystem at a time. Dr. X and his assistants would gather around whichever subsystem was believed to be farthest out of line and shout at each other in a mixture of Shanghainese, Mandarin, and technical English for a while. Therapies administered included but were not limited to: turning things off, then on again; picking them up a couple of inches and then dropping them; turning off nonessential appliances in this and other rooms; removing lids and wiggling circuit boards; extracting small contaminants, such as insects and their egg cases, with nonconducting chopsticks; cable-wiggling; incense-burning; putting folded-up pieces of paper beneath table legs; drinking tea and sulking; invoking unseen powers; sending runners to other rooms, buildings, or precincts with exquisitely calligraphed notes and waiting for them to come back carrying spare parts in dusty, yellowed cardboard boxes; and a similarly diverse suite of troubleshooting techniques in the realm of software. Much of this performance seemed to be genuine, the rest merely for Hackworth's consumption, presumably laying the groundwork for a renegotiation of the deal.
Eventually they were looking at the severed portion of John Percival Hackworth on a meter-wide sheet of mediatronic paper that one of the assistants had, with great ceremony, unfurled across a low, black lacquer table. They sought something that was bulky by nanotech standards, so the magnification was not very high– even so, the surface of Hackworth's skin looked like a table heaped with crumpled newspapers. If Dr. X shared Hackworth's queasiness, he didn't show it. He appeared to be sitting with hands folded in the lap of his embroidered silk robe, but Hackworth leaned forward a bit and saw his yellowed, inch-long fingernails overhanging the black Swiss cross of an old Nintendo pad. The fingers moved, the image on the mediation zoomed forward. Something smooth and inorganic unfolded at the top of their field of view: some kind of remotely controlled manipulator. Under Dr. X's direction it began to sift through the heap of desiccated skin. They found a lot of mites, of course, both natural and artificial.
The natural ones looked like little crabs and had been quietly inhabiting the outer layers of other creatures' bodies for hundreds of millions of years. The artificial ones had all been developed in the past few decades. Most of them consisted of a spherical or ellipsoidal hull with various attachments. The hull was a vacuole, a wee bit of the eutactic environment to coddle the mite's machine-phase innards. The hull's diamondoid structure was protected from the light by a thin layer of aluminum that made mites look like miniature spaceships– only with the air on the outside and the vacuum inside.
Attached to the hulls were various bits of gear: manipulators, sensors, locomotion systems, and antennas. The antennas were not at all like the ones on an insect– they were usually flat patches studded with what looked like close-cropped fuzz– phased-array systems for sweeping beams of visible light through the air. Most of the mites were also clearly marked with the manufacturer's name and a part number; this was demanded by Protocol. A few of them were unmarked. These were illicit and had been invented either by people like Dr. X; by outlaw phyles who spurned Protocol; or by the covert labs that most people assumed were run by all the zaibatsus.
During half an hour's rooting around through Hackworth's skin, roaming around an area perhaps a millimeter on a side, they observed a few dozen artificial mites, not an unusual number nowadays. Almost all of them were busted. Mites didn't last very long because they were small but complicated, which left little space for redundant systems. As soon as one got hit with a cosmic ray, it died. They also had little space for energy storage, so many of them simply ran out of juice after a while. Their manufacturers compensated for this by making a lot of them.
Nearly all of the mites were connected in some way with the Victorian immune system, and of these, most were immunocules whose job was to drift around the dirty littoral of New Chusan using lidar to home in on any other mites that might disobey protocol. Finding one, they killed the invader by grabbing onto it and not letting go. The Victorian system used Darwinian techniques to create killers adapted to their prey, which was elegant and effective but led to the creation of killers that were simply too bizarre to have been thought up by humans, just as humans designing a world never would have thought up tile naked mole rat. Dr. X took time out to zoom in on an especially freakish killer locked in a death-grip around an unlabeled mite. This did not necessarily mean that Hackworth's flesh had been invaded, rather that the dead mites had become part of the dust on a table somewhere and been ground into his skin when he touched it.
To illustrate the kind of mite he was presently looking for, Hackworth had brought along a cocklebur that he had teased from Fiona's hair after they had gone for a walk in the park. He had shown it to Dr. X, who had understood immediately, and eventually he found it. It looked completely different from all the other mites, because, as a cocklebur, its sole job was to stick to whatever touched it first. It had been generated a few hours previously by the matter compiler at Bespoke, which, following Hackworth's instructions, had placed a few million of them on the outer surface of the Illustrated Primer. Many of them had been embedded in Hackworth's flesh when he had first picked the book up. Many remained on the book, back at the office, but Hackworth had anticipated that.
He made it explicit now, just so Dr. X and his staff wouldn't get any ideas: 'The cocklebur has an internal timer,' he said, 'that will cause it to disintegrate twelve hours after it was compiled. We have six hours left in which to extract the information. It's encrypted, of course.'
Dr. X smiled for the first time all day.
Dr. X was the ideal man for this job because of his very disreputability. He was a reverse engineer. He collected artificial mites like some batty Victorian lepidopterist. He took them apart one atom at a time to see how they worked, and when he found some clever innovation, he squirreled it away in his database. Since most of these innovations were the result of natural selection, Dr. X was usually the first human
