The highway tunnel swallowed the survivors in a long curve of darkness, and the daylight behind them faded much faster than Arthur liked. The entrance had looked wide from outside, but once they moved deeper, the tunnel narrowed around them with rows of abandoned cars, broken road signs, and vines hanging through cracks in the concrete roof. Their lanterns spread weak yellow circles across the wet road, showing lane markings that disappeared beneath mud, old debris, and black water gathered in uneven pools.
Arthur walked near the middle of the line with Nora on one side and Sam on the other, while the survivors moved ahead in tense silence. The tunnel smelled of damp concrete, burnt rubber, old fuel, and the stale air of a place that had been closed for too long. Somewhere behind them, beyond the entrance and the misty valley, the false colony and the Pallbearer were still moving, which gave every step the unpleasant feeling of being borrowed from something larger and less patient.
Mara kept the group in a tight formation, with scouts ahead and guards walking backward near the rear. Sable moved beside her near the front, using her metal rod like a walking stick while still somehow managing to look personally offended by every crack in the tunnel walls. Elias leaned on Sam for the first few minutes until Rina forced him onto a makeshift carry strap between two stronger survivors, and Sam accepted the change with the face of someone trying very hard not to be useless.
Arthur looked back once and saw the tunnel entrance shrinking behind them into a pale oval of grey light. Shapes moved in the mist outside, not close enough to see clearly, but close enough for his shadow to tighten under his shoes. The darkness beneath him stretched slightly toward the rear, then pulled itself back as if even looking behind them cost more strength than it could spare.
The entity spoke faintly inside his head, its voice rougher than before. Do not stare backward unless you intend to become a lighthouse for the scavenger, because apparently your skull has become a decorative beacon for everything with teeth and ambition.
Arthur turned forward. "Noted," he muttered.
Nora looked at him without slowing. "Shadow?"
"Yes."
"Useful?"
"Rude with practical undertones."
"That sounds like useful."
Arthur considered that and decided she was probably right, which was annoying because Nora had a habit of being right at times when it brought no joy to anyone. He kept walking, placing each step carefully because the tunnel floor was slick and his ankle felt like it had developed a formal objection to continued travel. Every few yards, the lantern light caught signs of old panic, bags dropped between cars, doors left open, and faded handprints on dusty windows.
The survivors avoided the cars whenever possible.
Mara had warned them not to touch anything with glass, and after the observatory, nobody needed that warning repeated. Still, the tunnel made avoiding glass difficult, because windshields, mirrors, and side windows lined both lanes like hundreds of dull eyes. Arthur kept his gaze on the painted road lines, though even those sometimes seemed to bend when the lanterns passed over them.
A child near the front whispered something to their mother.
The sound was tiny, but the tunnel carried it too well.
From somewhere inside a nearby car, another child whispered back.
Everyone stopped.
The reply had come from a blue sedan on the left lane, its windows fogged from the inside even though the car had clearly been abandoned for years. The mother pulled her child close and covered their mouth gently, while Mara lifted one hand to hold the line. Arthur stared at the sedan despite every lesson the night had thrown at him, because the whisper from inside sounded young, frightened, and almost real.
The fog on the sedan's rear window shifted.
A small handprint appeared from the inside.
Nora caught Arthur's sleeve before he moved even one full step. "No," she said softly.
"I was not going to open it," Arthur whispered, offended mostly because part of him had considered exactly that.
Sable moved toward the car with her rod raised, keeping her eyes on the metal frame rather than the glass. "The tunnel is full of old reflections, old fear, and far too many sealed little rooms," she said, speaking quietly enough that the words stayed near the front of the line. "The false colony does not need to be inside every car, because it only needs you to wonder if it is."
The handprint slid down the glass.
Then it vanished.
Mara signaled the line forward again, and everyone moved faster without being told. Arthur followed, trying to ignore the cars on both sides, which became harder when several radios crackled to life at once. Static poured from dead dashboards, followed by fragments of voices that did not quite form words until the survivors had passed another thirty feet.
"Arthur Pringle," one radio said.
"Lane closure ahead," said another.
"Meeting delayed," said a third, in Arthur's own voice.
Arthur clenched his jaw and kept walking.
Nora stayed close. "Do not answer."
"I am developing a strong policy of ignoring myself."
"That sounds healthy."
"It is probably overdue."
The radios clicked off together.
For several minutes, the tunnel offered only its own normal horrors, which included dripping water, groaning concrete, and the occasional distant scrape from behind them. Then the road sloped downward, and the air grew colder. The lanterns showed a stretch of tunnel ahead where dozens of cars had been pushed sideways into a rough barricade, not by people, Arthur thought, but by floodwater or something heavier than floodwater using the highway as a drain.
Mara sent two scouts ahead.
They moved between the cars carefully, stepping over broken bumpers and twisted guardrails while keeping their lights low. One scout crouched near a gap beneath a bus, then looked back and raised two fingers. The route continued under the blocked vehicles, but only through a crawlspace barely tall enough for a child and wide enough for one person at a time.
Mara's expression tightened.
Arthur understood why immediately. The Pallbearer was behind them, the false colony was around them, and now the highway itself wanted them to crawl under a bus like extremely unlucky mechanics. He looked toward the ceiling, then at the drainage channels along both sides of the road, because his brain had started searching for alternatives before fear finished complaining.
"There may be a service walkway behind the right wall," Arthur said.
Sable turned toward him. "Why?"
He pointed to a line of small access panels spaced evenly along the concrete. "Those panels are too regular to be random, and the drainage channel curves toward them instead of continuing straight, which usually means there is a maintenance run behind the wall." He looked at the flooded ditch beside the road and frowned. "Or there was, before everyone responsible for maintaining it became unavailable."
Mara stepped closer to the wall and scraped mud from one panel with her boot. A rusted handle sat beneath the grime, almost invisible until the lantern hit it. She looked at Arthur as if deciding whether to be impressed or annoyed, which Arthur felt was fair because he often felt both about himself.
"Can it take the group?" she asked.
Arthur studied the panel, the spacing, and the shape of the wall. "If it still exists behind there, probably in single file, but it may bypass the vehicle pile."
Nora placed one hand on the handle and pulled.
Nothing happened.
Arthur sighed and stepped forward with the pipe. "Civilization has fallen, but stuck access panels remain loyal to their traditions."
Sam wedged his crowbar under the lower edge while Arthur worked the pipe into the rusted seam. Together they forced the panel outward with a long metallic shriek that echoed so sharply down the tunnel that everyone froze after it ended. Arthur looked back, waiting for the answer he knew was coming.
Far behind them, something answered.
It was not a roar.
It was a deep shift of pressure, like the tunnel itself had inhaled.
Mara's voice hardened. "Open it faster."
Sam pulled again, and the panel broke loose from the wall, revealing a narrow service passage behind it. The space beyond was dark but dry, with cable trays along one side and a raised walkway that ran parallel to the highway tunnel. Arthur lifted his lantern and saw the passage continue past the vehicle barricade, though the ceiling dipped in places where concrete had cracked and settled.
Mara did not waste time thanking anyone. "Children first, then injured, then supplies, and nobody touches exposed wiring."
The line began feeding into the passage, slow but steady. Arthur stayed near the entrance with Nora and Sam, helping people step across the drainage channel and into the narrow opening. The cars beside them remained silent now, but the silence felt like a choice rather than peace.
Half the group had entered when the first window broke.
It happened behind them, farther down the tunnel, a sharp crack followed by the sound of glass falling onto pavement. Then another window broke. Then another. The sound traveled toward them car by car, each break closer than the last, as if something unseen was walking through the traffic and opening every sealed space along the way.
Mara turned toward the rear guards. "Hold until the last group is inside."
The guards lifted flares and rods.
Arthur looked past them and saw movement between the abandoned cars. Pale hands slid out through broken windows, followed by arms, shoulders, faces, and bodies folding through openings too small to release anything human. The false colony was no longer pretending to be clean office rooms or polite waiters. It was coming out of the tunnel's dead traffic, wearing fragments of faces it had stolen from the road.
Sable swore softly with impressive academic venom.
Nora shoved another survivor through the access opening. "Arthur, inside."
Arthur looked at the exposed service passage, then at the access panel lying on the ground. "We need to close this behind us."
"That panel is broken."
"I did not say close it well."
Sam understood first and grabbed the fallen panel with both hands. Arthur helped him drag it closer to the opening while Nora kept her knife raised toward the approaching shapes. The rear guards lit two flares, and red light spilled across the tunnel, making the false bodies hesitate between the cars.
A woman's voice called from the traffic. "Please help me."
A man's voice followed. "My daughter is trapped."
Then came Arthur's voice again, calm and reasonable. "This route is unsafe. Please return to the main corridor."
Arthur tightened his grip on the panel. "I sound unbearable."
Nora did not look back. "Focus."
The last child entered the service passage, followed by two injured survivors and Rina carrying the medical bag. Mara backed toward the opening with Sable beside her while the rear guards retreated one step at a time. The false bodies moved forward again, crawling over hoods, through windows, and across the roof of the bus with their faces shifting under the flare light.
Arthur and Sam lifted the broken panel.
The hinges were ruined, but the panel could still cover most of the opening if they jammed it into the frame. Arthur shoved the top edge into place while Sam kicked the bottom inward, and the metal scraped across concrete with a sound that made Arthur's teeth hurt. The panel stuck halfway, leaving a gap near the floor large enough for a hand.
A hand immediately reached through.
Arthur hit it with the pipe.
The hand withdrew.
"Better," he said, breathing hard.
Mara came through the opening last, followed by the two rear guards. Nora slipped in after them, and Sam pulled the panel tight from inside while Arthur jammed the pipe through the handle and into a cable bracket to hold it shut. A pale face pressed against the gap near the bottom and smiled sideways through the dark.
"Arthur," it whispered.
Nora drove her knife through the gap, and the face vanished.
"Thank you," Arthur said.
"Stop thanking me for stabbing things."
The service passage shook as bodies struck the broken panel from the highway side. The pipe held, though it bent slightly with each impact. Arthur backed away with the others, moving along the narrow walkway while the false colony scratched and whispered behind them.
The passage was tighter than the highway tunnel but easier to move through once they got going. Cable trays lined the right wall, and old ventilation ducts ran overhead, some bent and others split open where the concrete had shifted. The air was dry enough that Arthur noticed his wet clothes more, which seemed like his body's deeply unhelpful way of reminding him he remained uncomfortable.
The group moved in single file for several minutes, passing the blocked section of highway through the hidden service route. Arthur could still hear the false colony behind the wall, moving parallel to them in the main tunnel, tapping on panels and whispering through cracks. Sometimes the voices came as strangers. Sometimes they came as people from Harbor Exchange. Once, near a cracked vent, they came as Dr. Voss.
"Run," the voice whispered from the dark.
Arthur looked at Sable, but she kept her eyes ahead and said nothing.
At last the service passage ended at another access panel, this one half open and looking out over the far side of the vehicle barricade. Mara sent scouts through first, and they returned with the kind of cautious relief that made Arthur trust the route only slightly more than before. The highway beyond was clear enough to move, though the tunnel split ahead into three lanes divided by old signage.
They emerged from the passage one by one.
Arthur stepped back onto the highway floor and looked toward the split.
The first junction had arrived.
Three routes opened ahead beneath faded overhead signs. The left tunnel sloped downward toward CENTRAL EXPRESSWAY and was flooded nearly to the curb. The middle route continued straight toward NORTH HIGHWAY, but its lights flickered in a long row of white rectangles that looked uncomfortably like office windows. The right route curved upward toward SERVICE EXIT 9, where cold air moved through the darkness and carried the faint smell of smoke.
Mara studied the options in silence.
Sable lifted her rod and watched the light bend around each tunnel mouth.
Nora looked at Arthur's shadow.
Arthur looked too.
The shadow stretched toward the right route, hesitated, then split faintly toward the flooded left tunnel before snapping back into one thin shape. Arthur felt the entity stir inside his head, tired and unclear, as if even it disliked the choice.
Right is faster, it whispered. Left is quieter. Straight is a trap wearing fluorescent lights, which should offend you on principle.
Arthur repeated the useful part aloud. "Straight is a trap. Right is faster, left is quieter."
Mara looked at the right tunnel, then the left, then back toward the way they had come, where the false colony had begun striking the service wall from the other side. "Faster matters if the Pallbearer is close," she said.
Sable frowned. "Quieter matters if the right route opens near the surface."
A low vibration moved through the highway behind them.
Dust fell from the ceiling.
The Pallbearer had entered the tunnel.
Arthur felt it before anyone heard it clearly, a cold pressure rolling through the concrete and into his bones. The false colony went silent all at once behind the walls, and that silence frightened him more than the whispers. Even the things wearing human voices were afraid of what had followed them.
Mara made the decision. "Right route."
The survivors began moving toward Service Exit 9.
Arthur followed with Nora, Sam, and Sable close by, while the tunnel behind them filled with a slow, distant scraping. He did not look back this time, because he knew exactly what was coming, and knowing did not make the shape easier to see. Ahead, the right tunnel climbed into darkness, carrying the smell of smoke, cold air, and something else Arthur could not name until they reached the first bend.
There were voices ahead.
Not false voices.
Real ones.
People were shouting somewhere beyond the curve, and under the shouts came the unmistakable sound of gunfire.
