Null Signal

The Fourth Rule

The rain had stopped, but the water was still rising.

It ran down the stone steps of St. Anselm’s and pooled in the gutters, thick and black with oil and dirt. Carter walked fast. Rook walked beside him. She was pale, her left arm tucked tight against her ribs, but she hadn’t slowed down since they left the church. She moved like a soldier who knew that stopping meant dying.

“Where are we going?” she asked. Her voice was tight with pain.

“Doctor,” Carter said.

“The Directorate has medics. The safehouse has a kit.”

“The Directorate put me in a cell for three years. I’m not walking into their clinic. And you need a real doctor, not a field kit.”

Rook didn’t argue. She just adjusted her good hand on the strap of her bag and kept walking.

They moved through the Lower Shelf, keeping to the narrow streets. The sky was turning gray. Morning was coming. Carter counted the turns—left, right, a long stretch of alley, a set of stairs that went down instead of up. The Cut was getting closer. He could feel it in the air, the way the damp seemed to settle into his bones. The buildings leaned closer together here, their roofs almost touching, blocking out the pale morning light.

They stopped at a door at the bottom of a stairwell. It smelled like bleach and old water. Carter knocked three times.

A slot in the door slid open. A pair of eyes looked out, flicked to Rook’s bloody arm, then to Carter’s face.

The door opened. A man stood there—older, broad-shouldered, with gray dreadlocks tied back and careful hands. He wore a stained apron over a thick sweater and held a small flashlight.

He looked at Rook’s arm. Then at Carter.

“Inside,” he said.

The room was small. A cot, a table, a shelf full of glass jars. Dr. Nkemdi didn’t ask questions. He pointed at the cot, and Rook sat.

Carter stood by the door, listening to the street outside. He didn’t sit. He kept his hand on the pistol in his pocket. The room smelled like iodine and boiled water.

“Bullet went through,” Nkemdi said, peeling back the makeshift bandage. “Clean exit. But you’ve been moving on it. It’s torn. I need to stitch it. It will hurt.”

“Do it,” Rook said.

Nkemdi opened a metal tin and pulled out a curved needle and a spool of black thread. He poured clear liquid from a bottle onto a cloth and pressed it to the wound. Rook’s jaw tightened. She didn’t make a sound.

Carter watched her face. He watched the way she held completely still, her eyes fixed on the wall. She was good at pain. Too good. It was another piece of a puzzle he couldn’t solve. He knew she was hiding something. He knew she was reporting to someone. But she was also the only person in Port Callow who had put herself between him and a bullet.

Nkemdi worked. The needle went in and out. The thread pulled tight. Rook didn’t flinch.

“You’re good at this,” Nkemdi muttered, tying off the stitch.

“I’ve had practice,” Rook said.

When Nkemdi finished, he washed his hands in a metal basin. He dried them on a clean rag and turned to Carter.

“Now,” he said. “You are the one.”

Carter didn’t move. “The one what?”

“The one the woman is looking for.”

“What woman?”

Nkemdi walked to the shelf. He picked up a glass jar. Inside was a small metal device—the size of a thumbnail, with wires coiled around it like a dead insect.

“This is what they put in his head,” Nkemdi said.

“Whose head?”

“His name was Elias. He worked for The Directorate. Eleven years ago, he came to me with headaches. He was seeing things. He was writing things he didn’t remember writing. He was finding notes in his own hand that gave instructions he couldn’t remember receiving.”

Carter felt the hair on his arms stand up.

“He was conditioned,” Carter said.

“Yes.”

“Like me.”

“I don’t know you,” Nkemdi said. “But I know what it does. I know the rules of it. If you want to know them, I will tell you. If not, leave. I have a business to run.”

“Tell me.”

Nkemdi set the jar on the table. The glass clicked against the metal surface.

“Three rules,” he said. “One. The trigger has to be physical. It cannot be a mood or a suggestion. It has to be a physical act. Elias wrote. Every time he picked up a pen, the conditioning took over. He would write a report, and then his hand would write a second version on the same page. He would wake up with two different pages in his own handwriting and no memory of either.”

Carter thought of the folder in his coat. The log entry dated tomorrow. The fifth line he hadn't written.

“Two,” Nkemdi said. “The rewrite is time-locked. The conditioning doesn’t alter the report the moment it’s filed. It waits. Twenty-four hours. The second version appears a day later. That’s how whoever is reading them compares the two. They see what you saw before you saw it.”

“Three,” Nkemdi said. “The conditioning burns out. It doesn’t last forever. Elias’s burned out two years after he was released from the program. When it burned out, he remembered everything. Everything he had done while under. Everything he had been told to do.”

“What happened to him?” Carter asked, though he already knew the answer.

Nkemdi looked at the floor. “He was told to kill himself. He did it three days later. I found the note. It was in his own hand.”

The room was silent. The rain had started again outside, a soft tapping against the door. Rook was sitting on the cot, her arm freshly stitched, staring at Carter.

“There is a fourth thing,” Nkemdi said.

“You said three rules.”

“It’s not a rule. It’s a warning. The conditioning doesn’t just rewrite your reports. It rewrites your sense of yourself. Elias didn’t just lose his memories. He lost his story. He couldn’t tell you who he was. He knew his name and he knew how to make coffee, but everything else was gone. He had to build himself from scratch. And when he remembered, he couldn’t live with the man he had been.”

Carter looked at his hands. Steady. Always steady.

“Thank you,” he said.

“You didn’t come here for a lecture,” Nkemdi said.

“No.”

“You came for something else.”

Carter reached into his coat and pulled out the metal box from the church. He opened it and took out the list of names. He handed it to Nkemdi.

“Do you know any of these?”

Nkemdi looked at the list. He read down it slowly. Then he stopped.

“Owen Voss,” he said.

“You know him?”

“Everyone knows him. He came to Port Callow ten years ago. He wasn’t a director then. He was a man in a suit. He disappeared for six months. When he came back, he was running a facility under the Lower Shelf.”

“What facility?”

“A bunker. Old, from the war. Below the Cut. Where they took the men who didn’t come back.”

“How do you know?”

“Because I was one of the men they took.”

Rook stood up, her good hand bracing against the wall. “You were in the program?”

“I was in the room next to it. I was medical staff. I saw what they did. I saw them break people. When the program ended, they let me go. I’ve been in the Cut since.”

Carter stepped forward. “Do you know a man named Marcus Hale?”

Nkemdi was quiet for a moment. “Yes. He was in the program before you. He was the one who ran it for a while. Then he turned against it. Then he died.”

“That’s the story,” Carter said. “What’s the truth?”

Nkemdi didn’t answer.

The room was quiet. Then, from the street outside, there was a soft sound.

A piece of paper sliding under the door.

Carter drew his pistol. He motioned for Nkemdi and Rook to stay back. He stepped to the door, yanked it open.

The stairwell was empty. The rain had started again, light and misty. There was no one on the stairs. No one at the top.

Carter looked down. A folded piece of paper lay on the mat.

He picked it up. He unfolded it.

The handwriting was his own.

Thursday. 03:00. Go to the bunker alone. Do not take Rook. Do not take anyone. The man you’re looking for is already inside. — M.

Carter read it twice. The top of the page had a date. Tomorrow. The signature was M. The handwriting was his own.

The same slant. The same loop in the letter g.

Marcus Hale had been dead for three years. But someone was still writing in his hand. And now, someone was writing in Carter’s.

Carter folded the note and put it in his pocket. He didn’t look back at Rook. He just stared out into the wet street, his mind racing.

If the note was real, it meant the conditioning had already produced tomorrow’s instructions. And if following the instructions was the trap, then he was already caught. If the note was fake, it meant someone wanted him to go in alone. Which was worse.

Either way, he should have told Rook. He should have showed her the paper.

He didn’t.

He turned back to the room.

“What is it?” Rook asked.

Carter looked at her. He thought about the note. Do not take Rook. He thought about the rules. The physical trigger. The time-lock. The burnout. The warning.

He thought about the fact that he was supposed to leave her behind.

“Nothing,” Carter said. “It was a draft. Wrong door.”

He walked to the cot and picked up his coat.

“We need to go,” he said. “Now.”

“Where?” Rook said.

“Down,” Carter said. “We need to find the Fisherman.”

Rook stared at him. She knew he was lying. He could see it in her eyes. She was an operative, and she could read him the way he read a room. But she didn't push. She just stood up, picked up her jacket, and followed him out the door.

Outside, the rain was getting heavier. The streets were slick. Carter looked at the stairs leading down into the dark of the Cut.

They walked in silence for ten minutes. The buildings got older. The streets got narrower. The air got heavier.

Carter kept his hand in his pocket, his fingers brushing the grip of his pistol. He kept his eyes on the reflections in the shop windows and the dark mouths of the alleys.

They reached the edge of the Cut. The stairs descended into the vertical slum, disappearing into the fog and the shadows.

Carter stopped. He looked down.

He didn't know if he was walking toward his past or his future. He only knew the direction was down.

And he knew, with absolute certainty, that if he wasn't careful, he was going to walk into that bunker completely alone.

He took a step down.

Then he heard it.

A soft tap. Tap. Tap.

Not water. Not footsteps.

A metallic tap, coming from the dark below.

Someone was waiting at the bottom of the stairs.

Carter drew his gun. Rook drew hers.

They weren't alone. And whoever was down there had been waiting for them to arrive.
