The street was empty when Nadia said it.
Your father.
That’s what he told people.
I didn’t answer. Mira’s hand was still on my wrist. Dana had stopped walking three steps behind us. The rain had started again, thin and cold, the kind that doesn’t fall so much as hang in the air and wait for you to walk into it.
Nadia didn’t push. She stood there with the phone in her hand, the file still open on the screen, and waited the way someone waits when they’ve already decided you’ll come back to them.
I looked at the file. Then at the street. Then at Mira.
"I need to sit down," I said.
"Not here," Nadia said. "Follow me."
She turned and walked. Not fast. Not slow. The pace of someone who knew I would follow.
I followed.
The diner was two blocks away. Closed. The owner knew Dana. He didn’t ask questions. He gave us a booth in the back and left.
Nadia sat across from me. Mira sat beside me. Dana stood by the door, arms crossed, watching the street through the glass.
Nadia set her phone on the table. Screen up. The file still open.
PROJECT ELIAS.
PHASE TWO.
SUBJECT: KAEL MERCER.
"How long have you had this?" I asked.
"Three weeks."
"And you waited until now to show me?"
"I didn’t know who you were three weeks ago." She tapped the screen. "I knew the name on the file. I didn’t know the man walking around with it."
Mira leaned forward. "Where did you get it?"
"From a source."
"What source?"
"A source I’m not going to name until I know what’s happening to the people who talk to me."
I looked at her. "How many have disappeared?"
"Three. In two years. All of them connected to that building. All of them connected to the file."
"And the source?"
"Stopped answering eight days ago."
Dana spoke from the door. "You’re saying the file is dangerous."
"I’m saying the file is alive." Nadia turned the phone around. "Every time I open it, the metadata changes. Creation date. Last modified. File size. Different every time. I’ve made copies. The copies change too."
Mira looked at me.
I looked at the file.
"Your father’s initials," Nadia said. "E.V. On the original permit. Seventeen years ago. Before the building was built."
I didn’t say anything.
"He’s listed as the project lead," she said. "Not the architect. Not the contractor. The project lead. The man who designed what goes inside."
Mira’s hand found mine under the table. I felt it. Barely.
"Where is he now?" Nadia asked.
"Dead."
"How?"
"Car accident. Seven years ago."
"And you saw the body."
"I was twelve. My mother made me identify it."
Nadia didn’t blink. "Did you?"
"There wasn’t much to identify."
The diner was quiet.
Nadia closed the file. She put the phone face down.
"Tuesday," she said. "Bring me something I can’t explain. Then I’ll tell you what I know about your father."
"Tuesday is four days."
"Then you have four days."
Outside, the rain had stopped. Dana was waiting by the car.
"You didn’t tell her about the building," Mira said.
"No."
"Why?"
"Because she already knows about the building. She’s been tracking it longer than I have. If I tell her what’s inside, she’ll go in."
"And that’s bad?"
"That’s bad."
Mira stopped walking. "Kael."
I stopped.
"You’re doing it again."
"Doing what?"
"Deciding what people can handle before they decide for themselves."
I looked at her. "You want me to tell her?"
"I want you to stop treating everyone like a variable."
She wasn’t angry. That was worse. She was tired. The kind of tired that comes after you’ve been afraid for too long and your body stops producing adrenaline and just leaves you standing there with nothing.
"I’ll think about it," I said.
"No, you won’t."
"You don’t know that."
"I know you." She walked to the car. "That’s the problem."
Dana drove me home. Mira came with us. Neither of them spoke.
When I got out, Mira got out too.
"I’m staying," she said.
"Your apartment is on the other side of the city."
"I know where my apartment is."
"You don’t have to."
"I know I don’t have to."
She walked past me to the door.
I stood on the sidewalk for a moment. My left arm hung at my side. I flexed the fingers. They moved. I couldn’t feel them move. The wind touched my face. My neck. My right arm. Nothing on the left.
I followed her inside.
In the morning, I found her asleep on the couch. She hadn’t taken her coat off. Her phone was on the floor beside her, screen dark, battery dead.
I made coffee. With my right hand. The left hand I kept on the counter, palm up, so I could look at it.
The mark had crossed the wrist. It was climbing the forearm now. The red line was brighter than it had been yesterday. Not glowing. Just — brighter. The way a vein looks under thin skin.
I touched it with my right hand. Warm.
I touched the same spot on my left arm. I couldn’t tell if it was warm. I couldn’t tell if it was anything.
Mira stirred.
"You made coffee," she said.
"I made coffee."
She sat up. Rubbed her face. Looked at my arm.
"Show me."
I showed her.
She got up. Crossed the room. Took my arm in both hands. Pressed her thumbs along the line. Followed it from wrist to elbow.
"Can you feel this?"
"No."
"This?"
"No."
She pressed harder. To the bone.
"Nothing?"
"Nothing."
She let go. Stepped back. Looked at me the way she looked at patients she couldn’t diagnose.
"How much of it is gone?"
"Wrist to shoulder. Everything."
"Everything."
"Yes."
"What about the mark itself? Can you feel that?"
I looked at it. "Yes."
She frowned. "That’s not possible."
"I know."
She sat back down. "We need to go back to the building."
"No."
"We need to know what it did to you."
"I know what it did to me."
"You don’t know how to reverse it."
"There’s nothing to reverse. It’s gone."
"You don’t know that."
"I know what I can’t feel."
She went quiet. Then: "Fine. Then we need to know what it means."
"That’s different."
"How?"
"Because knowing what it means won’t give me my arm back."
"No," she said. "But it might stop the rest of you from going the same way."
I looked at the mark. Then at her.
"Fine."
Dana’s shop smelled like burnt wire that afternoon.
She was at the workbench, soldering iron in hand, fixing a radio nobody had asked her to fix. It hissed faintly. Unplugged.
"Your journalist talks too much."
"You were watching the street."
"I was."
I set the permit photo down. The one Nadia had given me. E.V. blacked out. Initials visible.
"Demolition list’s been active six years. You never mentioned it."
She set the iron down. Pushed up her sleeve.
A thin scar ran her forearm. Pale. Uneven. Like the skin had torn from the inside out.
I hadn’t seen it yesterday. Because she hadn’t shown it.
"The man who went in and didn’t come out," I said.
"Not from him." She touched the scar. "From the night I went in after him. Twelve feet before something threw me back."
"Something?"
"Never saw a body."
"Not what I asked."
She met my eyes. "Last thing I saw was him standing in the dark. Facing me. Not answering. I called his name three times."
"Then?"
"Then the wall opened. And I woke up on the sidewalk. Twelve feet back. This on my arm."
"Why didn’t you tell me yesterday?"
"Because it doesn’t help you."
"Tells me you know more than you said."
"Tells you I’m not brave." She folded the sleeve back down. "Stubborn. Different thing."
She flipped the photo over.
"Filed for demolition the year after. Denied every time. Different excuse every round. Someone with real pull wants that building standing."
"Who?"
"If I knew that, I wouldn’t be running a shop full of dead radios."
The radio clicked. A voice bled through the static.
"Not yet."
She reached for the cord. Never plugged in. Pulled it anyway.
The bell rang. Mira came in fast, out of breath, a folded stack of papers under one arm.
"Patient records," she said. Dropped them on the counter. "Off the books. I know."
"You did it because I’d have told you to wait."
"I did it because I’m done waiting for permission to be useful."
Dana’s face shifted. Just slightly.
Mira unfolded the pages. Six patients. Eight months. Disorientation. Memory gaps. Sleep disturbance. A left-hand tremor with no matching diagnosis. All six within four blocks of Third and Morrow. Two "moved out of state." Both numbers disconnected.
Dana read over her shoulder. "Patient four. I know that name."
"You do?"
"Not personally." She tapped the address. "His sister came in two months ago. Asked if I knew anything about the building. Said he’d started standing in front of blank walls."
Mira’s face tightened. "Transferred to a psych ward in Ohio."
"Was?"
She didn’t answer.
The sound started under my skull. One thin metallic note. Not the slow build I’d gotten used to. All at once. My stomach dropped before I knew why.
```
[WARNING: UNREGISTERED SIGNAL]
[MATCH: PATIENT 04.]
[ARRIVAL: 40 METERS.]
```
Mira caught my face changing. "Kael?"
I was already looking at the window.
A man stood on the sidewalk. Three feet from the glass. Close enough that his breath should have fogged it in the cold. It didn’t. He wasn’t looking at the shop. His head was angled off. Like he was listening to the building instead of watching the people in it.
Dana went quiet. The ringing climbed.
Five seconds. Nothing moved but his left hand. A small tremor through the fingers. Then his head turned. Not like a man deciding to look. Like a machine taking a new instruction one joint at a time. The motion ran through his neck longer than it should.
His eyes found mine through the glass. The hum under my sternum answered.
"You know him?" Dana asked.
Mira’s voice lost its footing. "That’s patient four." She looked at the wristband under his sleeve. "He’s supposed to be in Ohio."
The tremor climbed his forearm. Muscles moving to a rhythm that didn’t belong to the rest of him. Dana’s hand drifted toward the pipe under the counter.
The door was locked.
He crossed the sidewalk. Each step landing too heavy. At the door, he studied the lock. Not like a man studies an obstacle. Like someone reading a keyhole they already understood. He pressed his palm to the wood.
"Don’t," Mira whispered.
Too late. He didn’t open the door. He walked through it. Frame and bell parting around him without a sound. Loose paper lifted off the counter for one impossible second before settling.
Dana stumbled back. Her hand found the pipe a beat too late for it to look like a plan.
He stood in the center of the shop. Up close, his eyes weren’t empty. Someone was still behind them. Still looking out. Unable to steer the rest of him. Worse than empty would have been.
His breath showed three seconds after he exhaled. When he spoke, two voices came out together. One half a beat behind the other. Like a damaged track playing over itself.
"You went inside."
The second voice scraped under the first. "You weren’t supposed to come back out whole."
My mouth went dry. "Who told you that?"
"It sent me. Because you stopped." The tremor hit his jaw, dragging the words sideways. "You’re not supposed to stop. You keep going. Keep finding. Keep breaking."
His head tilted. The second voice dropped low. Almost fond.
"It wants to see what happens when you finish."
```
[ROUTE STATUS: INCOMPLETE.]
[TIME REMAINING: 96 HOURS.]
```
The numbers settled into my chest like cold water.
Four days.
Mira’s fingers found the edge of the workbench. "What does it want?"
His eyes slid to her. For one beat, the voices fell out of sync.
"She’s the anchor."
"You’re the route."
Dana raised the pipe. "Kael." Quiet. "Move away from him."
He lunged. My arm came up on instinct. His hand closed around my forearm.
```
[EXTRACTION VECTOR: ACTIVE.]
[SOURCE → HOST.]
[COST CALCULATING.]
```
Cold poured into me. Not room-cold. Something stored away for years that had forgotten what living skin felt like. The hum surged. A line forming through my body from his grip to the pressure behind my ribs. Something on the other end pulling. Trying to draw a path through me toward whatever was waiting.
Copper flooded my mouth.
Dana screamed and swung with both hands. The pipe hit his shoulder with a crack that rattled the shelves. He staggered. Mira flinched into the wall.
Dana raised the pipe again. He turned toward her.
"Not her," I said. And got between them.
His hand rose slow. Fingers uncurling like he was reaching for something delicate. Stopped an inch from my chest.
"You’re not finished," both voices said together. Almost gentle. "It won’t stop asking until you are."
His knees buckled. Every muscle let go at once. He hit the floor hard enough to rattle the shelving.
```

[COST: 4%.]
[MEMORY INTEGRITY: 42%.]
[PERMANENT LOSS: TEMPERATURE — LEFT ARM.]
```
I didn’t feel the change while it happened. I felt it after. When I reached down to check his pulse with my left hand and couldn’t tell if his skin was warm or cold.
I couldn’t tell anything. My left arm had gone from wrist to shoulder without sensation. Not numb. Not asleep. Just — nothing. The skin was there. I could see it. Could move it. But when I pressed my fingers to his throat, the pressure came back from somewhere else. From the memory of pressure. Not from the arm.
Mira knelt beside me. Two fingers on his throat. Waiting longer than she needed before she trusted the pulse.
"Weak," she said. "He’s freezing."
Dana lowered the pipe by inches. "Actual hypothermic skin. Like he’s been outside for hours, not seconds."
Mira checked the wristband. "His facility’s in Ohio."
Dana stared at him. "Paperwork says eight months there."
The ordinary shop sounds came back slow. The heater. A car passing. Rain on the glass. Nobody touched him for a while.
Then I crouched and read the band. Real facility. Real date. Three weeks old.
Mira looked at me. "What did it mean — finish?"
"I don’t know."
"Kael."
"I don’t know."
This time it didn’t sound like an answer. It sounded like a door I hadn’t managed to open.
My phone buzzed. Nadia.
Followed the permit. Your father’s initials are on the original file. Call me before you ask anyone else about them.
Mira caught my face. "What is it?"
"Nadia found my father’s name on the building permit."
Dana looked at me and didn’t ask. Didn’t need to.
The patient’s fingers twitched against the floor. The second voice whispered. Too quiet for anyone but me.
"Driver."
I looked down. His eyes opened. Both pupils locked on me at once.
"Not registered," he said.
The front door clicked. Still locked. The bell rang anyway.
Mira’s hand closed on my wrist. Dana raised the pipe again.
Outside, the street sat empty. But under the ordinary hum of the city, the ringing waited. Patient. Metallic. Almost pleased with itself.
The patient smiled with someone else’s mouth.
```
[ROUTE STATUS: INCOMPLETE.]
[TIME REMAINING: 96 HOURS.]
[HOST STATUS: MARKED.]
```
"Keep going," the second voice whispered. "Or it comes inside."
Mira’s fingers tightened.
I tried to feel them. My right hand. Right wrist. Right skin.
Then I tried the left.
Nothing.
The only thing I could still feel on that side was the mark.
And it was warm.
That night, I sat on the floor of my apartment and opened the file Nadia had sent me.
PROJECT ELIAS.
PHASE TWO.
SUBJECT: KAEL MERCER.
I read it three times. Then I read the last page. A single line in my father’s handwriting.
If the subject reaches Phase Three, terminate the route.
I closed the file.
My phone buzzed.
Mira: Are you asleep?
Kael: No.
Mira: Me neither.
Mira: I’m outside.
I got up. Opened the door.
She was standing in the hallway. Coat on. Hair wet from the rain. She didn’t say anything. She just looked at me.
Then she stepped inside.
And I closed the door.
