Root of Unity (7 page)

“Arthur has your number,” I said. “And Pilar hasn’t even gotten there yet.”

“I know, but what if—” He sighed and took his glasses off, tossing them next to the keyboard in frustration and going back to typing.

Hell if I knew what he wanted from me. Just like Arthur.

I kept working, mixing in manual checks of the maps in the area and pulling cherry-picked data from the program’s algorithms to figure into my calculations.

“Arthur’s lost a lot of people,” Checker said suddenly, a few minutes later. “I’ll be damned if he loses one more, okay?”

“I didn’t say anything,” I bit out. “I’m helping, aren’t I?”

“I know. I know. I’m sorry.”

But Arthur hadn’t thought I’d be willing to jump in, either. He’d probably only forced himself to call me because he was willing to go to hell and back for this woman. To try everything.

Even me.

“What is it with him and Halliday, anyway?” I groused.

“What do you mean?” asked Checker. “He’d do the same for you, or me, or Pilar, or—or anyone else close to him. You know that.”

I sincerely doubted the part about me. I rubbed my eyes again and reapplied myself to the computer, hating everyone. My head still throbbed.

Checker stopped typing for a moment and leaned back. “They were best friends since they were about five, okay? Until, uh, a few years ago. They got each other through a lot, as kids. At least from my understanding of it.”

“Oh, best friends,” I said snidely. “Is that what they’re calling it?”

“What are you, a thirteen-year-old?” Checker snorted and went back to his keyboard. “I know I’m the last person you expect to say this, but not everything is about sex. Besides, Arthur’s had himself figured out since he was about ten. I’d be very surprised if anything ever happened between them.”

I’d never heard of Sonya Halliday before last night, and here was Checker with her whole life’s history. Everyone else had known what was going on here before Arthur had pulled me in for dumb computational comprehension and hadn't even trusted me to agree to be that.

I stabbed at the keyboard.

“Hey,” said Checker. “This might be the most inappropriate time to ask this ever, but are you okay?”

I kept stabbing. “Fine. It’s just a concussion.”

“I don’t mean
now,
although I’m glad to hear a concussion is included in your definition of ‘fine.’ I meant in general. Until today I hadn’t seen you in weeks. You’ve been ignoring all my messages—”

I tried to shrug him off. “I was on the job.”

“One, that’s never stopped you from mocking me through text before, and two, no, you haven’t been, at least not the whole time. I checked.”

“You were tracking me?” I put a little righteous anger into the words, even though I’d already figured he had been.

“Of course I was; I wanted to make sure you weren’t dead! What happened to coming over
here
to get your tequila on? There’s another season of
The X-Files
that’s begging us to play drinking games to it.”

“I didn’t feel like company,” I said, still concentrating on my screen. And maybe I’d been sick of trying to live up to his and Arthur’s standards, sick of trying so hard to be the human being they saw me as. Sick of failing at it.

“I get that,” said Checker, oblivious. “You just seem—I know, I know, concussion. But…you know if you need anything, that I’m—I mean, you can…right?”

I was saved from answering, thank Christ, by hitting the jackpot. “Hey. I found the van.”

Checker was at my shoulder immediately. “Where?”

I didn’t know how to do any sort of fancy computer highlighting, so I traced a rough circle against the monitor with my finger, ignoring it when Checker cringed. He didn’t like people touching his screens. “It disappeared into this area almost half an hour ago and hasn’t come out.”

“Are you sure? There’s no way it could’ve—?”

I glared at him, and he shut up.

“Okay, I get it, you’re sure. Two possibilities, then: their base is in the zone, or they switched vehicles. Can you run the security footage on the border of your zone forward and—never mind, I’ll do it,” he said hastily, at my blank look. He started punching keys. “You know, you could learn to do this stuff in about three seconds if you gave half a crap.”

I didn’t answer. Checker and I drank and watched bad movies together fairly regularly when I wasn’t avoiding him. It was stupid to think I wouldn’t see him anymore if I didn’t need him for the computer junk.

Stupid.

“It’s a bit of a long shot, but we can put together a likely vehicle list crossing the boundary,” Checker said absently, his focus on the screen. “Most cars that exit within the right window will be registered to people statistically unlikely to be involved, especially as stealing one would probably put our bad guys on the police radar more quickly and conspicuously. I’m skeptical this will work, though—I’m betting it’s not a coincidence they stopped out of view of any security cameras. These guys are very good at staying hidden.”

“Because nothing says ‘discreet’ like coming after Arthur and me with a grenade launcher,” I said.

“You might think that, but I assure you, I’ve been trying to trace that SUV since this morning with no luck. It’s like it popped up out of nowhere. I’m hoping Arthur will at least be able to get me a partial VIN. No, they might go in for the dramatic, but the way they’ve been disappearing in between—”

His hands froze on the keyboard.

“What?” I said.

Checker turned to one of his other machines without answering and started typing very fast.

“What is it?”

“I think—” His fingers slowed. “I think I know who it is.”

“What? What do you mean? You found who has Halliday?”

“Well, I
can’t
find them. But I think I would be able to if they weren’t wiped.”

“Hey.” I snapped my fingers at him. “Make sense.”

“I think it’s the Lancer.”

“Who’s that?”

“A black hat hacker. A pretty infamous one. So much of what I’ve been trying to track has been wiped, and I just realized—it’s his style, exactly. The way the information’s gone missing—it’s like a shadow. His shadow.”

“Wait a second,” I said. “Does this mean someone else would be able to trace
me
through data you’ve wiped? Because that doesn’t make me feel terribly secure—”

“Oh, leave it to you to make it all about you. Come on, Cas. I’m the best. And whoever else—” He cut himself off with a cough. “It’s different. This guy left traces.”

But whoever this was probably
felt
confident he’d wiped the evidence clean. Just like Checker felt confident. And with the NSA’s spying eyes being turned toward us right now…my thoughts soured.

“It’s not like I can tell he did it,” Checker continued. “It’s more like, I can tell things are gone, and the work is trademark Lancer. Thus, I’m assuming. If the Lancer’s not one of the people who has her, then maybe he’s someone close to them. Or works for them.”

I supposed there was nothing I could do about my own digital footprint anyway. Fucking information age. “How does this help us?”

“Because I might be able to trace him. Not to his location; he’s too good. But through his activities, by looking for his shadow, so to speak. I can figure out what he’s doing.”

“We know what he’s doing,” I said. “He’s going to code up an algorithm to Halliday’s proof and then they’re going to rob the world blind.” Shit, we’d been assuming the programming would take time, but these men already had half the equation: a computer expert who could do the work.

“But at least this is
something,”
argued Checker. “Maybe we can…I don’t know, lure him out?”

The idea hit me fully formed—something that would show both Arthur
and
the NSA, would let me solve this whole catastrophe once and for all. “No,” I said. “We don’t lure him out. We lure him in.”

“Huh? You mean you want to, to what—grab him and trade him?”

“No. Even if we got our hands on him, they wouldn’t trade the professor for him. He’s expendable. They can find another computer guy.”

“Hey!”

“You know it’s true. Halliday is the one they really need. Unless he’s the one in charge, they’d never trade him for her.”

Checker leaned back and crossed his arms. “All right, it seems like you’ve got an idea. Let’s hear it.”

“We don’t make them give up Halliday. We make them take me.”

“
What?”

“We convince them somehow that she needs help. That I wrote part of the proof. Whatever. You drop whatever electronic hints will make them think that.” I ignored the edge of recklessness limning my brain. This plan was perfect. “It’ll work. I can pass muster.”

“Of course you can; that’s not the point!”

“What is the point, then?”

“That—that you’re trying to offer yourself up as bait to people who nearly
killed
you and Arthur just this morning,
twice,
and have already kidnapped another person and what would make you think they’d want to keep you alive once they’d finished with you anyway? This is a terrible idea!”

“Come on, have you not met me?” I said.

“What—I don’t—”

“No one can keep me in a box. They catch me, they’ll take me to Halliday, I’ll get us both out. Easy as pie.”

“No. No, no, no, no, no. I don’t mean to rain on your frankly impossible skill set here, but even you can’t always bust your way out in a second once you get locked in a cell. You’ve admitted it before! There are so many ways this can go wrong, starting with, what if we make you a lure as bait and they just kill you instead of taking you in? Or what if they kill Professor Sonya because they think they don’t need her once they have you? Or what if—”

“We’ll just stall them on the math until I can figure a way out,” I said. “And you can drop the electronic hints so they’ll think they still need the professor. I have total faith in you.”

His mouth worked. “I am not in favor of this idea!”

“Tough,” I said.

“Goddammit. Where’s Arthur? Where’s Pilar? Where is some sanity? Why am I constantly surrounded by people who want to throw their lives down as martyrs? I’m not going to help you become—”

“I’m not trying to be a martyr!” I insisted. This wasn’t about self-sacrifice; this was about
winning.
“You’re the one who keeps telling me this is for Arthur!”

He shut up fast at that.

“They might be torturing Halliday as we speak, and this is the best plan we’ve got.” I stood up. “Start planting the evidence for this Lancer guy.”

“And where are you going to be?” asked Checker unhappily.

“I’m going to go find the van. That’s not a large search area—once I get out there, it shouldn’t take me long.” It was something to do, and maybe I’d be able to track their base and blast straight through to rescue Halliday. Besides, I didn’t want to be in the Hole if the NSA decided to check in here—Pilar had probably found Zhang by this point. “We’re going to get the professor back. One way or another.”

And Arthur would fucking
thank
me.

Chapter 7

I rode
my motorcycle out east, to the fringes of the LA sprawl.

I had a Eulerian path planned in my head for the search zone, spiraling through the dusty, ramshackle streets with my eyes flicking back and forth for any sign of the van. About a quarter of the way along it, I spotted the windowless white vehicle sitting abandoned at the far end of a fast food parking lot, overlooked by a garish cartoon burger over an atrociously comic sign. I pulled up to the van, jacked into it, and drove off, leaving the bike.

I moseyed around a few corners until I found a patch of empty road under an overpass, where I’d have some time to look suspicious without a danger of passersby getting curious. As I parked and got to work, I cursed Arthur under my breath for splitting off. I wasn’t nearly as good at crime-scening things as he was.

I scooped up a handful of fine road dust from the gutter and sifted it over various surfaces inside the van, blowing it off gently to look for fingerprints I could photograph and text to Checker—I’d picked up a burner of my own along with the bike—but the bad guys had been careful. The van was clean, and I only got covered in dirt for my trouble. I picked at the tires, but nothing recognizable in the treads leapt out at me. Mathematics might be useful for a lot of things, but it didn’t give me Arthur’s skills at observation.

I supposed I could take pictures, in case Arthur or Checker could find something useful in them later. I tossed my phone in my hand, feeling petty about having hit a dead end. Maybe I should drive the whole van back as evidence.

A screech of rubber on pavement burst against the cement walls of the overpass, shattering the quiet, and I dove behind the van just as three black SUVs skidded around the corner. My first thought was that the NSA had been on the hunt and followed the van here, too—

Then automatic weapons fire tore through the air, shredding my hearing, and the windows in the van’s cab burst apart in a shattering cacophony.

Holy shit, they tracked their own van!

I crouched against the tire well, drawing trajectories in my head and making sure the engine block was lined up between the weapons and me. My Colt was in my hand. I had eight rounds before reloading—how many men were there? With three SUVs, at least six guys would have come, and possibly more like twelve or eighteen. I listened, teasing out the gunfire—five people were firing right now, but that didn’t mean there weren’t more.

Screw it. I counted down from thirty, popped up as they reloaded, and fired at the first human being my gun crossed—a guy still in the driver’s seat of one of the SUVs. A pistol barked just as I pulled the trigger, and a line of fire lanced through my shoulder as I sat back down, hard. A round had clipped the skin between my shoulder and neck, on the right side. Less than an inch over and it would have hit my jugular.

Shit. Well, at least I’d nailed one of them. And I’d gotten a glimpse. Eight people at minimum, and maybe more I hadn’t been able to see.

There was a slight pause. Then a Molotov cocktail hit the ground right next to me.
