GHOST PHONE

CHAPTER THREE: SURFACE

Zane gave himself twenty minutes to figure it out. Maybe twenty-five.

He tried everything the phone would let him. Adjusting direction — the unit followed. Cutting the speed — it slowed, then crept back up the moment he stopped holding the slider. There was a camera toggle buried in the settings somewhere, and when he found it he switched to overhead view and watched the dot push through tunnels like something alive, something that had decided where it was going a long time ago.

No off switch. No return command. Not even a pause.

Whoever built this thing had never once imagined it ending up in the wrong hands.

Bibi Amina came back while it was still moving. He heard her at the door and shoved the phone under his mat and grabbed the circuit manual from the shelf, and by the time she stepped inside he was sitting at the table looking at diagrams of things he couldn't name.

She gave him the look. The one that didn't commit to anything yet.

Then she started unpacking — tomatoes, onions, something wrapped in newspaper — without saying a word, and for a moment he thought he'd gotten away with it.

"Anything interesting at the yard today."

Not really a question.

"The usual," he said.

"Mm."

One syllable. She could do more damage with one syllable than most people did with a whole argument. He kept his eyes on the manual.

When she went to the other room to pray, he pulled the phone back out.

The unit had surfaced.

The map put it three blocks from the Eastlands rail corridor — Mfumo Lane, which he knew, a half-commercial strip with secondhand furniture and a mandazi place and a printing shop that mostly did documents no one was supposed to have. The unit was in an alley between two buildings, standing still. Through the camera he could see a narrow frame of street: a man with a cart, two kids in uniform, a woman walking and talking and not looking at anything except whatever was ahead of her.

None of them glanced into the alley.

He kept watching. It just stood there.

Okay. It's just standing there. That's fine. That's nothing.

He was still telling himself that when his actual phone buzzed. The Samsung, cracked screen, four generations behind, sitting right there on the table.

Dex.

bro. u see the news???

He switched apps. NairobiNow. Top story, eleven minutes old, a clip someone had posted before anyone thought to stop them.

UNIDENTIFIED MACHINE SPOTTED IN EASTLANDS. VANE CORP INCIDENT?

Twelve seconds of footage. A dark alley — his alley, he was almost certain — and then something stepping out of the shadows. Wide. Heavy. That walk, that specific flat-footed walk he'd been watching through the unit's own camera for the last half hour, now filmed from the outside by someone who'd had no idea what they were seeing.

The clip cut off there.

Two thousand views. Comments moving faster than he could track them.

Zane sat with both phones in his hands and didn't move.

Then he got up, told Bibi Amina he was going to check something at the yard, and walked out.

DEX

Dex lived four floors down in the same block, in an actual room — not a half-room — which his mother had painted yellow on the theory that yellow made people feel like things were going to be okay. The router Dex had rewired three times suggested otherwise. So did the microwave he'd modified into a signal booster, and the kitchen light that now flickered twice before deciding to come on, which his mother had stopped trying to explain to guests.

Dex fixed things by breaking them differently.

He was also the only person Zane trusted without conditions.

Two knocks. Their code. Dex had the door open before the second one landed, goggles pushed up to his forehead, already running.

"You saw it?"

"I saw it."

"That thing on the news — the machine — it came from underground, Zane. I've been in the forums all morning. Old ones, buried. People have been saying it for years, that Vane Corp has something under the city. Not bots, not automation. Something they never announced." He was already turning back toward his screen when Zane held up the phone.

Dex stopped.

He looked at the phone. At Zane. At the phone again.

"Where did you get that."

"Jua yard. This morning. M.V. on the back."

Something moved across Dex's face — not quite recognition, more like the moment before it. "That's Marcus Vane's phone."

"Yeah."

"And you activated a unit."

"By accident."

"Obviously by accident." He took the phone the way Zane handled boards he hadn't identified yet — slow, careful, turning it to find the logic. He found the back. Ran his thumb over the etching. "No off switch."

"None."

"So it's still out there."

"Mfumo Lane. An alley. It's just standing there right now."

Dex handed the phone back and sat on the edge of his bed. For a moment he didn't say anything — which meant something, with Dex. Silence from Dex was actual thought, not a pause between thoughts.

"We need to know what they're for," he said. "A man like Marcus Vane doesn't build something under the city and never use it. There's a reason." He looked up. "And whoever lost that phone has been looking for it since this morning.

***

They went through it the way Zane went through scrap — no rushing, nothing skipped.

The map was the main screen but it wasn't the whole thing. Dex found the other layers by pressing combinations that had no business working, the kind of intuition you only got from years of making broken hardware do things its designers never intended. He'd press two things at once, wait, try a third. Most of the time nothing happened. Then something did.

The first layer was a ledger. Or close enough to one — a log, really. Timestamps, amounts, long strings of characters that Dex clocked almost before Zane could read them.

"Wallet addresses. Crypto." He leaned in. "And they're not random. Same amount, every seventy-two hours. Look at the size of these numbers."

Zane looked.

They weren't personal-ledger numbers. They were the kind of numbers that showed up in budget annexures, in line items that didn't have plain-language labels.

"Where does it go?"

Dex traced the chain as far as the phone would allow. Three hops, three different addresses, each one outside the country. The last one terminated somewhere he recognized.

"No extradition. No oversight. It's where money goes when it needs to not exist anymore."

The evening call to prayer started up from the mosque two streets over. The yellow walls caught the tail end of the sunset and went briefly, genuinely gold.

Neither of them said anything for a moment.

"He's stealing," Zane said.

"Something big. Something that runs on the NairoNet." Dex tapped the address strings. "The whole city moves through that blockchain — taxes, infrastructure, service payments. Everything. If you could get access at the right depth, the right node level—" He stopped.

"You could drain it."

"Slow enough that nobody sees it happening. Just numbers drifting down, month after month." He looked at Zane. "The units are how he gets in. Physical access to underground nodes. Nodes you can't touch any other way."

Zane thought about the unit on Mfumo Lane, just standing there in the dark between two buildings.

He thought about how the phone had felt in his vest all afternoon. The warmth of it.

He thought about the Jua yard, and where Jua yard tech came from, and how specifically this phone had ended up in that specific pile.

Someone dropped it to lose it. Or someone dropped it because they had no choice.

It didn't matter which. The answer came out the same: the phone was meant to be gone by now. And because it wasn't, someone was already doing the math on where it might have ended up.
