Ashil took out his cell and began to make calls. It was the early part of the night. “We need a conclave,” he said. “Big stake. Yes, make it.” “Conclave. At the set.” He said more or less the same many times.

“You can do anything,” I said.

“Yes. Yes… We need a show. Breach in strength.”

“So you believe me? Ashil, you do?”

“How would they do it? How would outsiders like that get word to her?”

“I don’t know, but that’s what we have to find out. Paid off a couple of locals—we know where that money came to Yorj from.” They had been small amounts.

“They could not possibly, not possibly create Orciny for her.”

“They wouldn’t have the CEO of their parent  here for these piddling little glad-handers, let alone every time Mahalia locks up. Come on. Besźel’s a basket case, and they’ve already thrown us a bone by being here. There’s got to be a connection …”

“Oh, we’ll investigate. But these aren’t citizens nor citizens, Tye. They don’t have the …” A silence.

“The fear,” I said. That Breach freeze, that obedience reflex shared in Ul Qoma and Besźel.

“They don’t have a certain response to us, so if we do anything we need to show weight—we need many of us, a presence. And if there’s truth to this, it’s the shutdown of a major business in Besźel. It’ll be a crisis for the city. A catastrophe. And no one will like that.

“It isn’t unknown for a city or a city to argue with Breach, Tye. It’s happened. There’ve been wars  with Breach.” He waited while that image hung. “That doesn’t help anyone. So we need to have presence.” Breach needed to intimidate. I understood.

“Come on,” I said. “Hurry.”

But the ingathering of Breach avatars from wherever they had posted themselves, the attempt with that diffuse authority, a corralling of chaos, was not efficient. Breach answered their phones, agreed, disagreed, said they would come or said they would not, said they would hear Ashil out. This was to judge from his side of the conversations.

“How many do you need?” I said. “What are you waiting for?”

“We need a presence , I said.”

“You feel what’s going on out there?” I said. “You’ve felt it in the air.”

There had been more than two hours of this. I was wired by something in the food and drink I had been given, pacing and complaining of my incarceration. More calls began to come in to Ashil. More than the messages he had left—word had gone viral. In the corridor was commotion, quick steps, voices, shouting and responding to shouts.

“What is it?”

Ashil was listening on his phone, not to the sound outside. “No,” he said. His voice betrayed nothing. He said it again several times until he closed the phone and looked at me. For the first time that set face looked like an evasion. He did not know how to say what he had to say.

“What’s happened?” The shouting outside was greater, and now there was noise from the street too.

“A crash.”

“A car crash?”

“Buses. Two buses.”

“They breached?”

He nodded. “They’re in Besźel. They jackknifed on Finn Square.” A big crosshatched piazza. “Skidded into a wall in Ul Qoma.” I did not say anything. Any accident leading to breach obviously necessitated Breach, a few avatars gusting into view, sealing off the scene, sorting out parameters, ushering out the blameless, holding any breachers, handing authority back as quickly as possible to the police in the two cities. There was nothing in the fact of a traffic breach to lead to the noise I heard outside, so there must be more.

“They were buses taking refugees to camps. They’re out, and they haven’t been trained; they’re breaching everywhere, wandering between the cities without any idea what they’re doing.”

I could imagine the panic of bystanders and passersby, let alone those innocent motorists of Besźel and Ul Qoma, having swerved desperately out of the path of the careening vehicles, of necessity in and out of the topolganger city, trying hard to regain control and pull their vehicles back to where they dwelt. Faced then with scores of afraid, injured intruders, without intent to transgress but without choice, without language to ask for help, stumbling out of the ruined buses, weeping children in their arms and bleeding across borders. Approaching people they saw, not attuned to the nuances of nationality—clothes, colours, hair, posture—oscillating back and forth between countries.

“We’ve called a closure,” Ashil said. “Complete lockdown. Clearing both the streets. Breach is out in force, everywhere, until this is finished.”

“What?”

Martial Breach. It had not happened in my lifetime. No entrance to either city, no passage between them, ultrahard enforcement of all Breach rules. The police of each city on mopping-up standby under Breach injunctions, adjuncts for the duration to the shutdown of borders. That was the sound I could hear, those mechanised voices over the growing roar of sirens: loudspeakers announcing the closure in both languages. Get off the streets .

“For a bus crash …?”

“It was deliberate,”  Ashil said. “It was ambushed. By unificationists. It’s happened. They’re all over. There’s reports of breaches everywhere.” He was regaining himself.

“Unifs in which city …?” I said, and my question petered out as I guessed the answer.

“Both. They’re working in concert. We don’t even know if it was Besź unifs who stopped the buses.” Of course they worked together; that we knew. But that those little bands of eager utopians could do this? Could untether this breakdown, could make this happen? “They’re everywhere in both cities. This is their insurrection. They’re trying to merge us.”

ASHIL WAS HESITATING. That kept me talking, only that, that he was there in the room minutes more than he needed to be. He was checking the contents of his pockets, preparing himself into soldierly alertness. All Breach were called out. He was expected. The sirens continued, the voices continued.

“Ashil, for Christ’s sake listen to me. Listen to me. You think this is coincidence? Come on . Ashil, don’t open that door. You think we get to this, you think we figure this out, get this far and all of a sudden there’s a fucking uprising? Someone’s doing this, Ashil. To get you and all the Breach out and away from them.

“How did you find out about which companies were here when? The nights Mahalia delivered.”

He was motionless. “We’re Breach,” he said eventually. “We can do whatever we need …”

“Damn  it, Ashil. I’m not some breacher for you to scare; I need to know. How do you investigate?”

At last: “Taps. Informants.” Glance up at the window, at a welling-up of the crisis sound. He waited by the door for more from me.

“Agents or systems in offices in Besźel and Ul Qoma tell you what you need to know, right? So someone somewhere was going through databases trying to find out who was where, when, in the Besź Chamber of Commerce.

“It’s been red-flagged, Ashil. You sent someone looking, and them pulling up files has been seen . What better evidence do you need that we’re onto something? You’ve seen the unifs. They’re nothing. Besźel and Ul Qoma, doesn’t make a difference, they’re a tiny bunch of dewy-eyed punks. There’s more agents than agitators; someone’s given an order. Someone’s engineered this because they’ve realised we’re onto them.

“Wait,” I said. “The lockdown … It’s not just Copula Hall, right? All borders to everywhere are closed, and no flights in or out, right?”

“BesźAir and Illitania are grounded. The airports aren’t taking incoming traffic.”

“What about private flights?”

“… The instruction’s the same, but they’re not under our authority like the national carriers, so it’s a bit more—”

“That’s what this is. You can’t lock them down, not in time. Someone’s getting out. We have to get to the Sear and Core building.”
