“What’s a bubble?” I asked.
“A temporary surveillance-free zone. Head back downtown, if you please. Park us anywhere off Nevsky, and we’ll walk.”
“Why do you want to go back to Nevsky? Isn’t that the first place they’ll look?”
“Who would expect us to circle back to the place where we were first identified?”
“Anyone with an ounce of imagination,” I said. “Anyone who’s ever read an American detective novel.”
He nodded. “You mean, anyone but a Postcop. Besides, they can look all they want; they won’t find us.”
I looked at him skeptically. “And what good does this bubble do us?”
“It gives you a chance to interview me.”
“Are you putting me on?” I glanced from the road to his face, which was unreadable. “You think I’m not in deep enough tea already, I should try Netcasting the life and times of a wanted criminal?”
“We can limit our discussion to the Calinshchina,” he said. “Your screener can alter my features, and elide any mention of my so-called terrorist activities.”
I thought for a moment. Keishi, can you make this ’cast clean? I mean a hundred percent, no traces whatsoever?
“In my sleep, girl.”
I decided that if she could make the Postcops forget about me, she could give me a clean Netcast; and if she couldn’t, then it wouldn’t matter. I might as well go ahead and get the story I was risking my career for. Besides, I was curious.
“All right,” I said grudgingly. “In for a penny, in for a pound.”
“That’s the spirit,” Voskresenye said brightly. “Nothing like a good cliché to help you to a wise decision.”
As I opened my mouth to answer, I heard a siren behind us. “Oh, God. Please tell me that’s an ambulance,” I said feebly.
“No. It’s a yellow-and-black,” he said. “Turn your head, as though you were looking for a place to pull over.”
“I hope you’ve got a backup plan,” I whispered, complying.
“That’s not for us. He’s chasing a speeder or something.”
“Look,” I said, “you’re wanted, you were seen, I was heard calling your name, now a Postcop comes out of nowhere. It stands to reason she’s looking for us.”
“Listen.” The wasp’s siren dopplered past, not even slowing. “You see? The Postcops are unimaginative, predictable, and overdependent on machines, but they are not stupid. In a matter of this importance they would not be so unsubtle as to send a wasp. If they come for us in a car, you may rest assured it will be unmarked and Net-silent.”
“How comforting.”
“You could not be safer than with me, Maya Tatyanichna,” he said with quiet amusement. “The Hanged Man is not in my cards. I am told to fear death by drowning, which has happened once already, and will happen once again—but not just yet.”
The traffic was now so thick that I had to devote all my attention to driving. At last, just a few blocks away from where we’d started, he silently pointed out a crowded parking lot. He had me park the car with its rear bumper to a wall, so the license plate would be hidden from the security camera.
“Our bubble is about a kilometer away,” he said. “I apologize for making you walk, but that way, if they do find the car—” he tapped its hood smartly, making the dashboard lights wink “—we’ll have some warning.”
As we walked I asked him what the terrorism charge on his record was for.
“The charge is actually ‘informational terrorism,’” he said.
“What?” I turned to face him, fear constricting my throat. “Informational terrorism? That’s not a Postcop crime. That’s under Weaver jurisdiction.”
“It happened a long time ago,” he said. “The Weavers have long since forgotten.”
“Weavers don’t forget.”
“They most certainly do,” he said. “Unlike the Postcops, the Weavers are entirely rational; that is their only point of weakness. If they are confident that you cannot repeat your crime, they will not seek you out. You need only stay offline for some years, and you will be entirely gone from their minds.”
Should I believe that?
“Sure,” Keishi said. “A Weaver sees a healthy chunk of the whole Net every day; they can’t remember all of it. For most things they rely on sense and reflex, not on memory.”
“How did this charge come about?” I asked Voskresenye.
“Some decades ago,” he said, “I was involved with a group of dissident hackers who wrote a virus designed to seek out the computers of every financial and governmental agency in the FHN. Only computers, you understand, not minds—otherwise it would have been far harder to get past the Weavers. It hid there until a certain day, then encrypted every byte of data it could find and self-destructed, leaving a series of ransom demands behind it. In effect, we were holding the information hostage.”
Why doesn’t that sound right to me? I subvoked.
“Ask him how he put an unbreakable code in the space of a virus,” Keishi whispered in my ear. “A virus would have to be small, to get so widespread without being detected. You could fit in a key a few thousand bits long, maybe, but you put a couple of teraflops on that and it’ll crumble.”
I paused to reorganize the question in my mind, then repeated it to Voskresenye.
“Oh, it did crumble,” he said. “It crumbled very quickly. We were astonished to discover that in some places it had held out as long as forty minutes.”
“Then what good was it?”
He looked at me out of the corner of his eye, not moving his head—almost, I thought, as though he couldn’t. “You might better ask, what good would it be otherwise? Do you think the Weavers negotiate with terrorists? What concessions will they give as ransom? Would they not instead hunt us down and kill us, even if it took a thousand men to take each one? If we had succeeded, it would have sealed our fates—such a simple trick as temporary disappearance would never have thrown them off, if I had done enough damage for them to take me seriously.”
“So you failed deliberately?”
“We invented a false purpose, and deliberately failed in that, yes. This was to conceal our true purpose.”
“Which was?” I prompted.
“To build a network of back doors into the computers that we infected. We knew that when they decrypted the data, after such a short time, they would not bother to check that what they recovered was the same as what they had before—especially since they had intercepted several copies of the virus, and made sure that their only function was to encrypt. We had only to hope they would not find the few copies of the virus that were subtly different from the others; and they did not. So the programs they restored had points of entry that had not been there before.”
“These back doors—wouldn’t they have found them eventually?”
“Certainly. But they remained in place only a few weeks. They were only meant to provide us access to the lowest levels of the system, a toe in the door. From there we could strip away the root passwords, letter by letter and bit by bit. And once we had root access, we could create all the back doors we dared. In that way, and by not doing anything that would alarm the Weavers unduly, we’ve managed to keep one step ahead of them ever since. The descendants of those original back doors are still being maintained. That’s how we’re able to create the bubbles.”
“Who do you mean when you say ‘we’? The people involved in this virus project?”
“Their current equivalents. All the members of that team have long since been disappeared, and those that followed them, and those that followed the ones that followed. You can evade the Postcops a long time, and the Weavers a short time; but in the end, they always catch you.”
