Helena turned to Slim. “Three hours in an aircar. He’s nearby. Not Los Angeles, or he would have had his own agents take Cat. San Francisco? Phoenix? Tucson? Someplace smaller?”
Helena rolled closer. Slim tried not to react, but his heart beat faster.
“Tucson?” Her working sensors focused and clicked. “Human, your biological chemistry gives you away. Tucson it is.”
“He may be coming to kill us,” Slim said.
“Irrelevant. If he’s going to kill you, he won’t be expecting me. If he’s picking you up, then I’ll come along for the ride. Either way, I’ll be a surprise.”

“You’re not focusing.”
“I’m trying. Back off.” Cat wiped a damp lock of hair away from her face. “I can concentrate better than anyone. These programs weren’t made for humans.”
Adam had arrived in a humanoid form that morning. The eldercare robot’s emotive face was meant to convey empathy and caring to those in need of assistance. It was equally capable of expressing frustration, even borderline anger, as he did now.
Adam whirled around. “Try again. Run the exercise at ten percent of nominal.”
“The speed isn’t the issue,” Cat said. She raised herself out of seated meditation and paced the width of Club Congress, the venue on the ground floor of the hotel. “It’s an artificial intelligence learning program, correct?”
“Yes, used to train neural networks. This program teaches how to route data packets.”
“How long would it take for an AI to master?” she asked.
“A minute for a Class I. Less for more advanced AI.”
“There’s nothing for me to grasp. Look, last week I didn’t know a thing about firearm combat. But I went through a few trainers, and I was able to pick up the techniques. The programs made sense because I already had martial arts training.” She gestured to the spinning ware image in their shared netspace. “But this abstract program isn’t connected to anything I understand.”
Adam was silent for a minute, until a new icon replaced the old one. “Try this.”
The package appeared to be a qigong training routine. “What is it?”
“Try the exercise.” Adam rolled away.
Cat shook out her arms, tucked her tailbone, bent her knees, and opened her shoulders. She studied the forms, but they were like nothing she’d seen. She followed the mental components, ignoring the physical movements. Push energy up, direct qi out, twist, focus. She completed the exercise once, then sped up the program.
Halfway through her eleventh run, a white light blossomed in front of her. She reached for it, and the light subdivided into a rainbow. With a mental push, she split the rainbow into colors, each expanding into a line of icons. The first represented people like they appeared in netspace, but more densely packed. Machines, AI, comprised the second row, and dumb computers the third. She swiped at the row of computers, and thousands blinked out.
The visual disappeared, leaving only the whitewashed wooden walls.
Adam rolled forward. “Very good.”
“What did I do?”
“You loaded a mental construct of the underlying routing protocol. Through intuition, brute force, and your unique implant hardware, you’ve done this on a rudimentary level until now. What you just accessed was the entire routing structure of Tucson, including every person and computer on the net.”
“Why did some disappear?”
“You disconnected them. Technically speaking, you sent an ICMP destination unreachable packet, an ancient protocol that underlies all routing. They’ll reset eventually, but for now they believe they can’t reach the net. That’s the level zero protocol.”
“Why did it look like qigong?”
“I mapped the interface to a metaphor you understand. If you mastered crochet, I could map it to a crochet pattern.” Adam paused. “You can also adjust routing tables at this level. Practice this and then I’ll teach you the next level.”
“Won’t I bring down the net?”
“The network is under my direct control. Anything you do, I can undo.”
Cat nodded. “Hajime.”
The program started again. This time she found the light and rainbow on the second run.
They continued the training until, by the time they stopped an hour later, she could find anyone, machine or person in seconds, change routing to fix problems or segregate the network, and insert herself in the middle of any transmission.
“It’s unbelievable,” Adam said. “You shouldn’t be able to inject yourself like that.”
“If I know the protocol, why are you amazed?”
“You haven’t been granted the necessary access. The routers require encryption keys you don’t possess.”
Cat shrugged. “Whatever. I can do it. What’s next?”
“We head up the stack, and I teach you application protocols. Let’s try the payment system, which you seem to be familiar with. Hajime.”
A new spinning icon appeared in netspace.

“You’re an idiot,” Mike said. “You injected experimental nanites for an untested implant. From a bot with no medical qualifications, no less.”
“Dude, give up.” Leon scratched his scalp. “The procedure’s done.”
Mike hung his head, elbows on knees.
“I’m sorry,” Leon said. “You complained we can’t understand these AI. Now I’ll be able to.”
Leon had rested on the bed while the nanotech did its work. An hour after the injection his implant rebooted, a new icon labeled Local Apps glowing in the corner of his vision.
Leon sat up, getting a headache for his trouble. “This is blistering fast.”
He opened a connection to Shizoko, shopping for supplies on the other side of town. Shizoko’s self-image rendered in rich detail, more vibrant than the real world. “Woah, the resolution…”
Shizoko smiled. “I’m glad the technique worked.”
“Do you know the AI’s location yet?”
“Yes, but I don’t want to transmit over the net. I’ll tell you in thirty minutes. We’ll be there in two hours.”
Leon relayed the conversation to Mike, who argued with him over “unacceptable risks” until they realized Shizoko was ten minutes late. Leon called but couldn’t establish a connection.
“He must be busy,” Leon said, trying to cultivate optimism.
“Impossible. He’s a Class IV capable of holding hundreds of simultaneous conversations—” Mike jumped up, his face in shock. “We have to get out.” He sent links to articles.
Leon glanced at the first, a live blog covering a downtown accident. A city bus had crashed into a gas meter outside a survival gear store, setting the building aflame and blocking the front door. An automated garbage truck obstructed the rear exit, trapping eleven people and two robots in the inferno.
“Shizoko must have been one of the bots,” Leon said. “He was getting supplies.”
Leon scanned the next post about a violent riot outside Austin Convention Center that caused an electrical grid failure and the possible loss of Shizoko Reynolds, owner of the Convention Center. The National Guard had been called in.
“Do you think he survived?” Mike asked.
Leon’s hands shook. “Even if Shizoko had backups, he’d go into hiding after someone eliminated his data center and a remote bot simultaneously. We’re on our own.”
“Whoever attacked Shizoko could know we’re here,” Mike said.
Leon checked for signs of searching, probing further into the network than he’d ever done before the upgrade. “Nothing’s out of the norm in our vicinity.”
