"Looks pretty flimsy," Clarke remarks. "Not much to keep us out."
"It's not there for us," Lubin says.
"Well, yeah." It's a ßehemoth filter, obviously. And it must be blocking a whole range of other particles too, to generate this kind of density imbalance. "What I mean is, we can just punch right on through."
"I don't think so," Lubin says.
He brings the periscope down from the surface and sends it sniffing towards the barrier; on the panel, the cowering cityscape disappears in a swirl of bubbles and darkness. Clarke glimpses the 'scope's tether through the viewport, a pale thread of fiberop unwinding overhead. The periscope itself is effectively invisible, a small miracle of dynamic countershading.
Clarke watches it on tactical instead. Lubin brings the drone to within half a meter of the membrane: a faint yellow haze resolves on the right-hand feed, where naked eyes see only darkness. "What's that?" Clarke wonders.
"Bioelectric field," Lubin tells her.
"You mean it's alive?"
"Probably not the membrane itself. I'd guess it's run through with some kind of engineered neurons."
"Really? You sure?"
Lubin shakes his head. "I'm not even sure it's biological—the field strength fits, but it doesn't prove anything." He gives her a look. "Did you think we had a sensor to pick up brain cells at fifty paces?"
No witty rejoinder springs to mind. Clarke turns back to the viewport, and the dim blue aurora flickering beyond. "Like an anorexic smart gel," she murmurs.
"Probably a lot dumber. And a lot more radical—they'd have to tweak the neurons to work at low temperatures, high salinity—the membrane itself could handle osmoregulation, I suppose."
"I don't see any blood vessels. I wonder how they get nutrients."
"Maybe the membrane handles that too. Absorbs them right from seawater."
"What's it for?"
"Other than a filter?" Lubin shrugs. "An alarm, I should think."
"So what do we do?"
Lubin considers a moment. "Poke it," he says.
The periscope lunges forward. On the wide-spectrum display the membrane flares on impact, bright threads radiating from the strike like a fine-veined tracery of yellow lightning. In visible light it just floats there, inert.
"Mmm." Lubin pulls the periscope back. The membrane reverts to lowglow.
"So if it is an alarm," Clarke says, "I'm guessing you've just set it off."
"Not unless Halifax goes to red alert every time a piece of driftwood bumps their perimeter." Lubin runs his finger along a control bar: on tactical, the periscope heads back to the surface. "But I am willing to bet this thing'll scream a lot louder if we actually tear through it. We don't need that kind of attention."
"So what now? Head down the coast a bit, try a land approach?"
Lubin shakes his head. "Underwater was our best shot. A landside approach will be a lot tougher." He grabs a headset off the bulkhead and slips it over his skull. "If we can't get to a hard line, we'll try the local wireless nets. Better than nothing."
He cocoons himself and extends feelers into the attenuate datasphere overhead. Clarke reroutes nav to the copilot's panel and turns Phocoena back into deeper water. An extra klick or so shouldn't interfere with Lubin's trawl, and there's something disquieting about being in such shallow water. It's like looking up to find the roof has crept down while you weren't looking.
Lubin grunts. "Got something."
Clarke taps into Lubin's headset and splits the feed to her own panel. Most of the stream's incomprehensible— numbers and statistics and acronyms, scrolling past too quickly for her to read even if she could make sense of them. Either Lubin's dug beneath the usual user interfaces, or Maelstrom has become so impoverished in the past five years that it can't support advanced graphics any more.
But that can't be. The system has room enough for her own demonic alter-egos, after all. Those are nothing if not graphic.
"So what's it saying?" Clarke asks.
"Missile attack of some kind, down in Maine. They're sending lifters."
She gives up and pulls the 'phones from her eyes.
"That could be our best way in," Lubin muses. "Any vehicles CSIRA deploys will be operating out of a secure site with access to good intel."
"And you think the pilot would be willing to pick up a couple of hitch-hikers in the middle of a contaminated zone?"
Lubin turns his head. Faint lightning flickers around the edges of his eyephones, ephemeral tattoos laid over the scars on his cheeks.
"If there is a pilot," he says, "perhaps he'll be open to persuasion."
Gehenna
Taka Ouellette emerged into a nightscape of guttering flame. She drove at a crawl through a hot dry snowfall, the windshield's static field barely keeping the flakes from the glass. Ash flurried white as talc in Miri's headlights, a fog of powdered earth and vegetation blinding her to the road ahead. She killed the lights, but infrared was even worse: countless particles of drifting soot, the brilliant washouts of raw flame, arid little dust-devils and writhing updrafts overloaded the display with false-color artefacts. Finally she settled for an old set of photoamp glasses in the glove compartment. The world resolved into black and white, gray on gray. The viz was still terrible, but at least the interference was in sharp focus.
Maybe there were survivors, she told herself without much hope. Maybe the firestorm didn't reach that far. She was a good ten kilometers from the spot where her MI had risen up and slaughtered the locals. There'd been no closer cover: no storm sewers or parkades more than a few levels deep, and if there'd been any hardened shelters nearby her surviving patients wouldn't have been inclined to tell her about them. So she'd fled east while the contrails arced overhead, buried herself in a service tunnel attached to an abandoned tidal bore drilled in from Penobscot Bay. A few years ago the shamans had promised that bore would keep the lights on from Portland to Eastport, world without end. But of course the world had ended, before the first turbine had even been installed. Now the tunnel did nothing but shield burrowing mammals from the short-term consequences of their own stupidity.
Ten kilometers over buckled and debris-strewn roads that hadn't seen service since before ßehemoth. It was nothing short of a miracle that Taka had made it to safety before the missiles had hit. Or it would have been, if the missiles had actually caused any of the devastation she was driving through now.
She was pretty sure they hadn't. In fact, she was pretty sure they'd never even touched the ground.
The hill she was climbing crested a hundred meters ahead. Fresh wreckage blocked her way halfway up that rise, the remains of some roadside building that had collapsed during the attack. Now it was only a great tumbledown collection of smoking cinder blocks. Not even Taka's eyeglasses could banish the shadows infesting that debris, all straight lines and sharp angles and dark empty parallelograms.
It was too steep for Miri's limited ground-effectors. Ouellette left the van to its own devices and climbed around the wreckage. The bricks were still hot to the touch. Heat from the scorched earth penetrated the soles of her boots, a subtle warmth, unpleasant only by implication.
On the uphill side of the debris she passed occasional objects which retained some crumbly semblance of human bones. She was breathing the dead. Perhaps some of those she inhaled would have died even earlier, if not for her efforts. Perhaps some she'd helped today were still alive, in spite of everything. She managed to take some faint comfort in that, until she crested the hill.
But no.
The landscape spread out before her was as wasted as the path she'd just climbed: flickering eruptions of white firelight punctuating a vista blackened as much by carbon as by nightfall. The land had not been laid waste by missiles or microbes, not this time. The thing that had done it was still visible in the distance: a tiny dark oval in the sky, barely darker than the cloud bank behind it, hanging a few degrees over the horizon. Taka almost missed it at first, even with the specs. Its outline was fuzzy, sparkling with the faint visual static of errant photons unreasonably boosted.
