The Dead Know the Door
The first knock came before Leo touched the handle.
It was not loud. Something struck the other side of the field-service lock once, waited, then struck again in exactly the same place.
Leo kept his hand above the control. The visor showed the door where it belonged. Raw mode kept a second outline a few centimeters to the left, then added a third. For an instant the same lock appeared to open onto three dark passages.
Another impact shook dust from the frame.
This time other hands joined it.
Gauss stood to the right of the door, clear of its centerline. Silver-gray plates covered the black mechanism of his suit; blue light ran between the joints. The heavy weapon in his hands was separate from the armor, its dark housing resting against his shoulder and its orange vents still cold.
“That was not on yesterday's recording,” Leo said.
“No.”
“Good. I was worried preparation had made this less interesting.”
Gauss opened the exterior camera feed.
The image lasted long enough to show a hand pressed flat against the outside release. Three fingers were missing. The wrist continued pushing after the display went black.
The lock shuddered again.
“The boundary is holding,” Gauss said. “The exterior mechanism is not built to survive this indefinitely.”
“How long?”
“Not long enough to wait for them to lose interest.”
The rifle felt lighter in Leo's calibrated frame than D-17's weapon ever had. That should have helped. Instead it made him more aware of the sealed shotgun on his back, the spare rifle magazine at his side, and the fact that every useful object Gauss had given him was about to leave the only clean room in Meridian.
Gauss glanced at his weapon status. “When the door opens, stay left of my line.”
“And if the other side is still three corridors?”
“Choose none of them until the floor agrees with your feet.”
The answer was useful. Leo hated that this made him feel better.
He activated the lock.
The door withdrew into the wall. A blue line remained across the threshold, thin enough to step over.
Beyond it, the outer containment apron was full of people.
They were packed shoulder to shoulder from the door to the service tunnel. Some wore work jackets. One woman still had a visitor badge clipped upside down to her coat. A man in a municipal vest leaned against the exterior control with both hands while another body pushed through him from behind.
None of them looked at Leo.
Their faces pointed toward the open doorway. Their mouths worked in the same rhythm.
“My daughter is upstairs.”
“Keep the line moving.”
“I left my key.”
“Platform three.”
Different voices. Different last needs. One cadence.
The man at the control tried to step through. His forehead struck empty air above the blue line and stopped. His body kept walking. Skin folded against nothing. Behind him, the crowd pushed harder.
The boundary refused him. His hands could still reach the lock.
Leo fired.
The first round struck the man's upper chest and threw him away from the control. The next hit the woman behind him. A third body climbed over both, and Leo put the third round through its shoulder before it could reach the release.
The suit took the recoil. Three brass cases spun across the clean side of the threshold.
For one breath, the floor outside cleared.
Leo crossed.
His boot landed on concrete that stayed beneath him. He moved left as Gauss had ordered. The raw outlines collapsed into one service tunnel, but the detector continued drawing pale lines from the door toward thresholds that did not exist on the physical plan.
Behind Leo, Gauss stepped outside. The field-service door began to close.
The bodies Leo had shot moved again—not the bodies themselves. Something black slipped out of the fallen man's wrist, crossed the floor like a tightened hair, and entered the arm of a woman still standing. A second line left the body near her feet and caught a maintenance worker by the jaw.
Both survivors jerked forward together.
The crowd changed shape.
It did not thin. The fallen became steps. Three pulls that had moved three bodies now drew two, and those two forced through the gap faster. The woman seized the exterior control. The maintenance worker dropped to all fours and pushed bodies toward the threshold with his back.
Leo raised the rifle again.
“Left wall,” Gauss said.
Leo moved before asking why.
Gauss cleared the threshold, turned, and planted himself between the lock and the crowd. The door sealed behind him. Its exterior control remained under the woman's hand.
A case of content theft: this narrative is not rightfully on Amazon; if you spot it, report the violation.
The heavy weapon's forward vents flared orange.
A white line crossed the apron and entered the mouth of the service tunnel. For an instant the people in its path became black shapes with light around their edges. Then the center of the crowd came apart and hot air struck Leo's armor.
Gauss released the trigger. The vents stayed bright.
The shot had opened a lane. It had not stopped the voices.
“Keep the line moving,” someone said from the tunnel floor.
Black threads pulled sideways through the fallen. Bodies against the walls began to stand.
Leo looked at the three people he had shot. He had not reduced the crowd. He had only moved its grip.
“I made it worse.”
“You established what happens when one falls,” Gauss said. “Use it.”
Three rounds gone. The woman at the control was still striking the door. Leo stopped counting bodies and watched the threads.
The exterior housing bent under her next blow.
Gauss pointed down the lane his shot had opened. “If we stay here, they keep the pressure on the lock.”
“So we move away from the door they're trying to reach.”
“And find what is pulling them toward it.”
Leo glanced at the lock status in his visor.
CLOSED / BOUNDARY INTACT / EXTERIOR CONTROL DEGRADED
“Can we still get back through it?”
“The control is responding,” Gauss said. “We have a return until that changes.”
Another body rose inside the tunnel.
Leo followed Gauss through the opening.
The service tunnel climbed away from the laboratory in a straight line until the detector insisted it did not.
Raw mode showed doorframes sliding across the walls. A staff exit appeared inside a cable cabinet, vanished, then returned behind Leo. None became solid enough to use. The dead did not hesitate. They came through the actual tunnel, dragging feet and broken limbs with the certainty of people following directions they could no longer understand.
Gauss moved behind Leo, heavy weapon lowered while its vents shed heat. That left Leo the clear lane ahead.
A man in a torn security uniform stepped from a maintenance recess. A dark thread ran from his wrist to the mouth of a woman crawling behind him.
Leo aimed at the arm instead of the chest.
His fourth shot broke the wrist against the wall.
The thread snapped taut. It did not retreat into the dark. Near the recess, one hand was already scraping weakly across the floor. The loose line caught the moving fingers, climbed the arm, and fastened itself beneath the body's chin.
The body inhaled without filling its lungs.
Its eyes opened.
Leo fired once into its knee before it could stand. The leg folded. The new puppet clawed at the floor, moving without enough leverage to block the tunnel.
Gauss dragged the security guard against the wall, clearing the route.
“Why that one?”
“It was already moving.” Leo kept the rifle trained on the corpse clawing toward them. The other bodies in the recess had not stirred. “It doesn't choose the nearest. It chooses the nearest one already moving.”
“Then leave the others down.”
Leo backed toward the ramp. He watched the hands now, not the faces.
They reached the utility ramp. Daylight—or something using the correct color—fell through the broken street entrance above. The ramp mouth provided a concrete corner before the open service plaza.
Leo stopped behind it.
The plaza contained fewer bodies than the apron. That made the pattern easier to see.
Threads crossed between a delivery driver, two office workers, a child in a raincoat, and a man whose lower body remained under a collapsed kiosk. None of the lines continued beyond the group. They ended at wrists, mouths, ankles, then began again from another body.
Above them hung a knot of black strands. It was no larger than Leo's fist. Every time one puppet moved, the knot tightened and another line answered somewhere else in the plaza.
The detector found no physical object inside it.
Leo's vision shifted.
D-RANK ANOMALY DETECTED
DESIGNATION: THE PUPPETEER
CAUSAL KERNEL: UNRESOLVED
OBSERVED RULE: A BROKEN LINK SEEKS THE NEAREST MOVING ELIGIBLE BODY
The interface named the anomaly but not its source. The black knot above the plaza remained the only target Leo could see.
“The knot above the plaza,” he said.
Gauss looked past the concrete corner. “Can you hit it?”
“Yes. I'm not sure the bullet can hurt it.”
“Then don't waste one finding out.”
Leo focused on the cartridge in the chamber. The fourth mark tightened beneath his sleeve.
TECHNICIAN'S FRENZY
Selected carrier: chambered rifle cartridge
Cost: 1 anomalous energy
Next impact only
His reserve changed from 80 to 79.
The number hurt more here than it had in the test bay. One point bought a result on a workbench. Outside, it bought one attempt while a dead child waited for the shot to go wrong.
Leo confirmed the charge.
Nothing changed in the sight. The cartridge did not glow. He felt the anomalous pressure settle through his grip and stop at the rifle's next impact.
The knot shifted.
The child in the raincoat stepped behind it.
Leo held the shot. The charged round would spend itself on its next impact whether he struck the knot or a yellow sleeve. The rifle remained steady. His breath did not.
Gauss said nothing. He kept the approaching office worker away from Leo's firing lane.
The child jerked sideways as another line tightened. The knot cleared the sight.
Leo fired.
The bullet passed through the center of the black strands. The concrete wall beyond burst in an ordinary gray chip. Across the plaza, every thread flashed blue.
The knot opened.
The delivery driver fell against a parked vehicle. One office worker stopped with a foot raised and toppled sideways. The child in the raincoat remained standing, arms slack, while loose strings searched across the pavement without finding a moving hand or mouth.
“Now,” Leo said.
They left the ramp.
Gauss advanced on Leo's right without raising the hot weapon. He pinned a twitching wrist beneath one armored boot before its movement could draw a loose string. Leo fired twice more, each shot breaking an exposed wrist or ankle where a line tried to settle. Gauss caught one falling body and laid it against a vehicle instead of letting it roll back into their path.
For several seconds, the plaza belonged to gravity again.
Behind them, the child in the raincoat slowly raised one hand.
A loose string found the movement.
Leo saw it in the edge of his visor and did not turn. He and Gauss were already past, and another shot would only move the pull again.
The civic arcade opened ahead, a covered passage lined with dark shops and evacuation signs. Leo crossed beneath the first sign and took the left side. Gauss backed in after him, stopping beside a shuttered pharmacy on the right while he watched the plaza. The central walkway remained open between them.
Their way back still existed: plaza, ramp, tunnel, apron, lock. Fresh bodies were already reaching the plaza from the utility ramp behind them.
An evacuation speaker hung above Leo. Its casing was cracked. No status light showed. The cable beneath it ended in a blackened stub.
It spoke softly in Leo's voice.
“I never left.”
Gauss did not react to the words. He was still watching the plaza.
His finger tightened on the trigger.
For a moment he was back outside the sealed bedroom in apartment 4812, listening to his own voice answer from the other side. The arcade blurred around the speaker. He could almost feel the paper seal beneath his fingertips.
The suit marked the sound as an isolated audio event.
Gauss still knew nothing about the second presence. Leo pushed the marker to the edge of his visor without opening the recording.
“Leo?” Gauss called from across the walkway.
The speaker stayed dead.
“The speaker came on,” Leo said. “It's dead again.”
Gauss's helmet turned toward the cracked casing.
The first body in the plaza turned its head.
Then every body carrying a visible string moved at once.
Some stood. Some crawled. One dragged two others still caught beneath the same dark line. They did not come toward Leo. The crowd streamed through the open walkway between him and Gauss, then ran into the far end of the arcade, all in the same direction.
Gauss looked after them. “The knot wasn't the source.”
The last bodies were already disappearing into the arcade.
“Looks that way,” Leo said. “They're the only trail we have.”
He moved after them. Gauss fell in beside him.
Leo watched the black threads stretch between wrists, jaws and ankles as the crowd disappeared deeper into central Meridian.
The strings still ended at different bodies.
The bodies all ran the same way.
