CinciGen's onboard had sent contagion warnings to all its friends in Maelstrom. Each friend had bred the warning and passed it on, a fission of sirens. None of these agents were human. Humans had had no role in the process at all so far. That was the whole point. Humans wouldn't have been fast enough to cut off a thousand facilities by lunchtime.

Humans had stopped complaining about such extreme measures right after the 38 enceph pandemic.

Jovellanos conferenced in. "False alarm."

"What?"

"That's what sent up the alarm," Jovellanos told him. "Screen grab from the hospital's pathfinder."

"Details."

"The pathfinder takes swabs from the ventilation filters and cultures them for nasties. This particular culture plate went from zip to thirty-percent coverage in two seconds. Which is impossible, of course, even for hospital paths."

But the system hadn't known that. Some bannerbug had dumped its load into visual memory and the pathfinder had just been doing its job, looking for dark blotches on light backgrounds. Who could blame it for being illiterate?

"This is it? You're sure?" Desjardins asked.

"I checked the ancillaries: no detectable toxins, proteins, nothing. The system was just playing it safe—figured anything that bred that fast had to be a threat, and there you go."

"And Cinci doesn't know?"

"Oh, sure. They figured it out almost immediately. They'd already sent the abortions when I called 'em."

Desjardins eyed the schematic. Pinpoints continued to blossom at the periphery.

"Alarms are still going off, far as I can see," he said. "Double-check, will you?" They could always short-circuit the quarantine through a media broadcast— they could even phone around if they had to—but that would take hours; dozens, hundreds of facilities would be paralyzed in the meantime. Cinci had already sent out counteragents to call off the alarms. So why wasn't the core of Desjardins's schematic going green by now with successful aborts?

"They sent them out," Jovellanos confirmed after a moment. "The alarms just aren't responding. You don't suppose…"

"Wait a second." A star had just gone out on the schematic. Another one. Three more. Twenty. A hundred.

All of them white. All on the periphery.

"We're losing alarms." He magged on the nodes where the lights had winked out. "But way out on the edge. Nothing near the core." The abortions couldn't have jumped so far so fast. Desjardins spun down the filters; now he could see more than autonomous alarms and the little programs sent to call them off. He could see file packets and executables. He could see wildlife. He could see—

"We got sharks," he said. "Feeding frenzy at PSN-1433. And spreading."

Arpanet.

Internet.

The Net. Not such an arrogant label, back when one was all they had.

The term cyberspace lasted a bit longer— but space implies great empty vistas, a luminous galaxy of icons and avatars, a hallucinogenic dreamworld in 48-bit color. No sense of the meatgrinder in cyberspace. No hint of pestilence or predation, creatures with split-second lifespans tearing endlessly at each others' throats. Cyberspace was a wistful fantasy-word, like hobbit or biodiversity, by the time Achilles Desjardins came onto the scene.

Onion and metabase were more current. New layers were forever being laid atop the old, each free—for a while—from the congestion and static that saturated its predecessors. Orders of magnitude accrued with each generation: more speed, more storage, more power. Information raced down conduits of fiberop, of rotazane, of quantum stuff so sheer its very existence was in doubt. Every decade saw a new backbone grafted onto the beast; then every few years. Every few months. The endless ascent of power and economy proceeded apace, not as steep a climb as during the fabled days of Moore, but steep enough.

And coming up from behind, racing after the expanding frontier, ran the progeny of laws much older than Moore's.

It's the pattern that matters, you see. Not the choice of building materials. Life is information, shaped by natural selection. Carbon's just fashion, nucleic acids mere optional accessories. Electrons can do all that stuff, if they're coded the right way.

It's all just Pattern.

And so viruses begat filters; filters begat polymorphic counteragents; polymorphic counteragents begat an arms race. Not to mention the worms and the 'bots and the single-minded autonomous datahounds—so essential for legitimate commerce, so vital to the well-being of every institution, but so needy, so demanding of access to protected memory. And way over there in left field, the Artificial Life geeks were busy with their Core Wars and their Tierra models and their genetic algorithms. It was only a matter of time before everyone got tired of endlessly reprogramming their minions against each other. Why not just build in some genes, a random number generator or two for variation, and let natural selection do the work?

The problem with natural selection, of course, is that it changes things.

The problem with natural selection in networks is that things change fast.

By the time Achilles Desjardins became a 'lawbreaker, Onion was a name in decline. One look inside would tell you why. If you could watch the fornication and predation and speciation without going grand mal from the rate-of-change, you knew there was only one word that really fit: Maelstrom.

Of course, people still went there all the time. What else could they do? Civilization's central nervous system had been living inside a Gordian knot for over a century. No one was going to pull the plug over a case of pinworms.

Now some of CinciGen's alarms were staggering through Maelstrom with their guts hanging out. Naturally the local wildlife had picked up the scent. Desjardins whistled through his teeth.

"You getting this, Alice?"

"Uh-huh."

Sometime in the dim and distant past—maybe five, ten minutes ago— something had taken a swipe at one of the alarms. It had tried to steal code, or hitch a ride, or just grab the memory the alarm was using. Whatever. It had probably screwed up an attempt to fake a shutdown code, leaving its target blind to all signals, legit or otherwise. Probably damaged it in other ways, too.

So this poor victimized alarm—wounded, alone, cut off from any hope of recall—had blundered off through Maelstrom, still looking for its destination. Apparently that part of the program still worked: it had bred itself, wounds and all, at the next node. Primary contacts, to secondary, to tertiary—each node a juncture for geometric replication.

By now there were thousands of the little beggars in the neighborhood. Not alarms any more: bait. Every time they passed through a node they rang dinner bells for all and sundry, corrupted! defenseless! File fodder! They'd be waking up every dormant parasite and predator in copy range, luring them in, concentrating the killers…

Not that the alarms themselves mattered. They'd been a mistake from the outset, called into existence by a glorified typo. But there were millions of other files in those nodes, healthy, useful files, and although they all had the usual built-in defenses—nothing got sent through Maelstrom these days without some kind of armor—how many of them could withstand a billion different attacks from a billion hungry predators, lured together by the scent of fresh blood?
