Root of Unity (29 page)

“Revolutionize mankind, I know,” said Arthur. “What are you gonna do? Twist her arm until she shares it with you?”

“You don’t get it!” I cried. “You say ‘revolutionize’ like you understand, but you
aren’t getting this.
This is—it’s bigger than splitting the atom, or the combustion engine, or—or the invention of electricity, or whatever other technological revolution you’re thinking of. You don’t understand what this proof would mean!”

“Then maybe Martinez is right,” said Arthur, “keeping it to herself. Maybe that’s the right call here.”

“That’s
never
the right call!”

Checker pulled open the door to the Hole and came out. “Cas. Hey.”

“You’re going along with this?” I cried. “You? Mr. ‘Knowing is Always Better Than Not Knowing?’ Did he
tell
you what we found?”

“Cas—”

“This is bigger than you, than me, than all of us!” I ignored the guilty twinge acknowledging that wasn’t the reason I wanted it, and stabbed a finger at Checker. “
You
should understand that!”

And he should understand what it meant for me. He should
know.
The fact that he should have connected how important this was for me but was still siding with Arthur—it hurt, a deep and private pain I buried ruthlessly under my anger.

“I do—I get it; this is…” Checker trailed off and waved his hands limply, as if he couldn’t figure out how to encompass something as huge as P equaling NP. “Cas, how can this not terrify you? If this proof is right, if Turing machines are that much more powerful than we thought—will human innovation even mean anything anymore? Not just in mathematics, but everywhere—engineering, new technologies—there’ll be nothing left human intelligence can offer above a computer. Nothing. And then what? Humanity becomes superfluous? Dr. Martinez said she thought this would break the world; what if she’s
right?”

If she was right it wouldn’t matter, because in the wake of the new apocalypse, I would be whole again. A true mathematician. Hell, I’d be more than a mathematician—I’d be a god.

I didn’t say any of that. “Coward,” I said instead. The word came out bitter. Hateful.

“Yes,” Checker admitted frankly. “I am. This scares me. Beyond belief.”

“And when has that ever stopped you?”

He hesitated. “If it were my decision, I’d…you’ve got a point; I’d probably close my eyes and take the leap, and scream while I was doing it. But Arthur’s right. It’s not my call. I’m not the brilliant mathematician who made the breakthrough. It was her accomplishment, and she made her decision pretty clear.”

Arthur made a small, approving noise.

“Stop parroting what he said to you,” I said.

A flush crept up Checker’s face. “I’m not.”

It had never occurred to me that Checker wouldn’t back me up. Arthur didn’t know what he was saying, didn’t grasp all the ramifications, but Checker—he should have been knocking me over in his desire to find Martinez. He should have been shouting at Arthur about this, throwing every resource he had into it,
insisting.
The fact that he wasn’t…he was betraying all of mathematics, betraying computer science—betraying me.

“If she found it, someone else will,” I said, aware I was blatantly contradicting what I’d told Arthur and Halliday earlier, but feeling too vicious to care. “And you’re making me hope that person does as much damage with it as they possibly can, because it’s your fault we won’t be ready.”

I started to stomp off, then turned back and added to Checker: “And you. You’ll let one old woman decide the fate of the whole world without a fight, but you won’t let me decide what’s right for my own life. Fuck you. I’m done.”

Checker tried to stutter a response, but I was already striding away.

I didn’t need them. I’d worked on my own long before I’d ever met Arthur or Checker. I would find Martinez somehow, with or without Halliday’s help, and I would pry the goddamn proof out of her if I had to lock her in a room and extract it.

Then I’d figure out if I wanted to share it.

Chapter 29

I made
it back to my car and stood there on the darkened street. I wasn’t sure where to start.

Fuck. In the past two years, I’d started to take it for granted I had Arthur and Checker around. I had a secure computer back in my apartment, courtesy of Checker, but I wasn’t much better than basic search engines.

Checker was right, damn him—I should have taken the time to learn. Computers were just math, weren’t they? I ignored the small voice in my head reminding me I’d never have the patience to keep up with the latest hardware, let alone memorize any sort of programming language.

And I couldn’t take the time now anyway. Fuck me twice.

Before Checker, I’d had an information guy. His name had been Anton Lechowicz. The last case I’d involved him in had killed him.

My hand twitched, and I wanted to put my fist through one of the car windows. I hated thinking of Anton.

And I’d never cultivated any backup contacts. I didn’t like working with people I didn’t know.

I got into the car and drove home, mulling as I did so, trying to remember who else in my line of work I remotely trusted. The list wasn’t very long. As soon as I got back I pulled a new phone out of a drawer—I’d burned the old one; Checker would be tracking it and I didn’t want him to—and called Ari Tegan, my friendly local forger. He was seriously competent and had desisted from giving me up to the Mafia the year before, which I didn’t really understand but which made me like him even more. He seemed to like me, too, for some reason. I wasn’t sure why.

“Tegan, it’s Cas Russell,” I said when he picked up.

“Cassandra! Hello! How are you faring?”

I winced. Tegan’s use of my full name had always bothered me, but now it echoed with the man from my dreams, the one who kept calling and pleading for something I couldn’t deliver, echoed against that name on a graveyard cover stone saying I’d died and the signature on the bottom of the note inside. I tried to let it roll off.

“Fine,” I said shortly. “I need an information guy. Someone good at tracking, data mining, that sort of thing. Can you give me any recommendations?”

“I usually send people to Arthur these days. I thought you worked with him as well?” I was one of the few people Checker knew in person and allowed to call him directly—most people just knew that one of the services of Arthur’s private investigations business was electronic data gathering.

“He’s busy,” I said. No need for Tegan to know the details.

“Hmm,” he said. “Mickey McTaggart is quite good. But she works for the Lorenzos. I gathered you resolved things with Mama Lorenzo, but are you still persona non grata with them?”

“I don’t know,” I said honestly.

“Then I am unsure.” He thought for a moment. “If you require sensitivity to discretion, I do not know of anyone else local I would trust, at least not anyone I would recommend as having a high level of skill. I do know of perhaps a surprising number of people who work virtually, who have been clients of mine or who have partnered with my services on occasion, and whose abilities have impressed me. I stress that I do not know their bona fides, only that they have been honest in their business dealings with me, and as far as I can tell would have the expertise you require.”

“I guess that’s better than nothing.” I preferred to meet people in person, in case I needed to track them down afterward for any reason. Particularly any reason that involved putting a gun to their heads. But there was some saying about beggars and choosers. “Anybody I can check out another way?”

“You might see if Arthur can check the names for you, if he is too busy to take the case,” suggested Tegan.
Yeah, right. Fat chance of that.
“I’m afraid they work pseudonymously, under screen names, but they do depend on those screen names for their reputations. Let me think. Griffon, Two Key, Doctor Yee, General Zephyr. Grep, Shift, the Lancer, Hijack, a newer gentleman called Lincoln—”

“Wait,” I said. The Lancer. Holy shit. “Go back.”

“I can email you a list,” Tegan offered, oblivious. “With their contact information, such as it is. You may give my name, if you like.”

“I’d appreciate that,” I said.

I hung up and stared at my computer screen, not seeing it.

One of the tidbits Checker had dropped while we searched for Martinez was that the Lancer had gone underground, unwilling to make contact with unknown entities for fear someone was an NSA plant. But if I had a reference from Tegan…if the Lancer could be assured I wasn’t a National Security agent in disguise…

I wasn’t very good undercover, but that was in real life. Virtually, it would be a lot easier to lie.

Holy crap. I might be able to track the Lancer when even Checker and the NSA couldn’t. Like I’d told Arthur, this job was over when I said it was, and I owed the Lancer a broken face.

Of course, none of that helped me find Martinez. I wondered if the Lancer was looking for her, too. If he’d figured out what she’d really proven.

Maybe I should tell him. With his obsession over the P versus NP problem, he’d stop at nothing in order to find her. Unlike Checker.

But then what? Letting the Lancer get his hands on the proof—or on Martinez, I reminded myself guiltily—wasn’t the most appealing option.

Except he would publish it. He’d tried so many times with his amateur work; he wouldn’t be able to stop himself. He’d get the algorithm out of Dr. Martinez, steal it, and publish it himself, and the whole world would be able to see.

The whole world. Including me.

Arthur wouldn’t approve,
said a voice in my head. Scratch that, not only would Arthur not approve of me sending a kidnapper and murderer after a slightly dotty old woman, he’d probably go as far as pulling a gun on me to try to stop me. I’d beat him, but that wasn’t the point.

Isn’t it? Arthur was just the one saying everyone should get to make their own decisions. Well, I should get to make this one!
The justification echoed in my head, sarcastic and mocking. I knew that wasn’t what he’d meant.

But Arthur had backed out of this whole case, so I should get to play it just like I would if I were going it alone. I remembered my sardonic promise to leave out the plastic explosives if I was working for him—well, I wasn’t working for him anymore, and that meant he didn’t get a say.

A niggling feeling reminded me that getting an elderly mathematician kidnapped by a killer wasn’t
my
MO, either.

“She brought this on herself,” I said aloud. Martinez had refused to share the proof and then stolen all of her colleague’s work to control this decision. She wasn’t innocent.

Can’t believe you’re even considering this,
said some vestige of conscience, in Arthur’s voice. I tried to ignore it and imagine what I would’ve been thinking two years ago, before I’d met him. Would I still have been having doubts?

I needed that proof. The reality of going on without it, when it was out there, when it could
fix
me—

“Find a way,” I growled. My fucking
job
was getting things back for people, and I was really fucking good at it. I could get this proof back, and I could use the Lancer, and I could double-cross him and bash his face in and make sure Martinez didn’t get killed but instead gave me what I needed, whatever it took.

A strange euphoria flooded me, and I felt alive and reckless. I could do this. And depending how it played out, when I was done, the world might never be the same. I might be one of the four horsemen of the apocalypse…or I might be a harbinger of the second coming.

The power of it was heady, almost like a drug. I wondered if that was a taste of what Martinez had felt.

My email chimed. It was Tegan, with the promised list. I scrolled down to find the Lancer. There was a web address to a forum and instructions for dropping a passcode.

I clicked over and left the correct message. I’d be giving my real name this time, since Tegan was giving me a reference. It would be fine as long as the Lancer didn’t ask him what I looked like.

I didn’t know how long I’d have to wait for a response. I should sleep. I shut the laptop.

This is a terrible idea.
I wasn’t sure if the voice belonged to me, Arthur, Checker, or the man from my nightmares.

“Shut up,” I said. “I’ll find a way.”

I flopped down on my bed, but couldn’t close my eyes. If I did, I would dream.

Chapter 30

By the time
my email chimed again, I had a plan.

The Lancer’s response to my overture was short and suspicious, but as Tegan had come through with the promised referral, he was willing to talk. Hopefully the revelation that someone had solved P versus NP would tantalize him enough to override any further common sense.

I felt a brief pang of guilt for screwing over Tegan’s good reference. If this ended the way I wanted it to, the Lancer and whoever among his men were unlucky enough to be with him would end up dead or in NSA custody. I mollified myself with the fact that “dead or muzzled by the NSA” meant they wouldn’t be able to go around spreading the gossip that Tegan’s word hadn’t been on the level.

I sent the Lancer a very clear, firmly-worded email laying out my plan, and then drove to Checker’s house and parked down the street.

I had to wait forever for him to leave. I was almost resigning myself to wondering if I’d have to break in with him still there when he came out of the Hole and got into his car. Even from this distance he looked exhausted, his movements dragging as he hauled his chair in behind the seat. Maybe it was the vantage point that made him seem thinner than normal.

He drove away. I waited seven minutes—I needed enough time to finish my robbery before he could get back, if his security system alerted his phone to my presence.

I pulled into his driveway, entered a code on the keypad on the side of his house that would disable his ruder security measures—he’d given it to me in case he was ever in trouble—and jimmied his front door open. Then I scooped up all Martinez’s notes that Arthur had grabbed from her home and work. It took two trips, but I was still out and driving away in no time at all.
