Chapter 3: The Sewer Ambush
The stale protein bar sat like chalk in Rosa’s mouth. She chewed slowly, her eyes closed, listening to the blood roar in her ears gradually soften into a manageable thrum. The ten minutes Roy had insisted on felt like a lifetime and a single blink simultaneously. Her muscles, screamed-at and abused, began the reluctant transition from live wires to sore, heavy meat.
Roy stood sentinel on the grimy floor, watching the immense, weary rise and fall of her chest. The penlight’s beam, now pointed at the ceiling, gave the room a dim, underwater glow.
“Think you can stand without face-planting?” he asked, his voice echoing slightly in the silent closet. A ghost of a smile touched Rosa’s cracked lips. “I think the floor’s safer.” But she opened her eyes, the green sharpening back to a familiar, grim focus. She pushed herself upright with a groan that was more performative than she intended. The room tilted for a second, then righted itself. “Okay. We’re okay.”
She reached for the crate of SR units. They were old police gear, clunky handheld radios with heavy battery packs. She checked four of them, flicking switches. Three had dead batteries, their indicator lights dark and mocking. The fourth, when she toggled the power, emitted a sharp crackle of static that made them both jump. A faint green light glowed weakly.
“One working unit,” she reported, her voice flat. “We’ll have to scavenge batteries for the others later.” She clipped it to her belt. “This changes the plan. We can’t coordinate a full team. It’s a one-way beacon.”
Roy paced a tight circle, thinking. “Then we simplify. We use it to draw him. You broadcast. Say you’ve got me, that you’re injured, that you’re heading for the drains because it’s the only place you can hide. He’ll hear the panic. He’ll come.”
“He’ll know it’s a trap.”
“He won’t care. You said it yourself. He’s a rat. He can’t resist the cheese. And to him, I’m the ultimate cheese.” Roy stopped, looking up at her. “But you have to sell it. Real fear. Real pain.”
Rosa’s jaw worked. The idea of bleating false vulnerability over the airwaves curdled something in her gut. But Roy was right. It was elegant. Bait for a predator. She picked him up, her hand warmer now, steadier. “Alright. But we do this smart. We pick the outflow chamber under the Chem wing. I know the grating there is loose from the inside. It’s a kill box with one back door.”
She tucked him back into her collar, not zipping it fully, leaving him a slit of a view. The journey to the storm drains was a study in controlled tension. They moved like ghosts through the university’s underbelly, Rosa using every service tunnel and steam pipe conduit she remembered from a forgotten campus map she’d once studied during a quiet day. The world outside Roy’s narrow window was a blur of dripping pipes, startled cockroaches, and patches of shocking, cold moonlight where ceilings had collapsed.
Finally, they reached a heavy, rusted door marked ‘FLOOD CONTROL – AUTHORIZED PERSONNEL.’ A chain and padlock hung from the hasp, shiny and new against the decay.
Silas’s work.
Rosa didn’t hesitate. She set her pack down, pulled out a compact bolt cutter from a side pouch. The snap of the chain was deafening in the silent corridor.She eased the door open.The smell hit them first. It wasn’t just wet concrete and rot. Underneath was a sharp, chemical tang—ozone, burnt wiring, and something coppery, like old blood. The air was cold and moved in a faint, damp draft, carrying the sound of dripping water from somewhere deep in the blackness.
Rosa flicked on her flashlight. The beam carved a tunnel through the gloom, illuminating a cylindrical concrete pipe about eight feet in diameter. Graffiti scars and calcified mineral deposits streaked the walls. The floor was slick with a thin layer of algae-scummed water. About fifty yards ahead, the pipe opened into a wider chamber, faintly lit by a flickering, failing emergency light mounted high on the wall. “This is it,” Rosa whispered, her voice absorbed by the damp. She moved forward, her boots making soft, sucking sounds in the muck. The chamber was a junction where several pipes met. In the center, a rusted metal grating covered a dark, rushing maw where water vanished into the depths. One of the side pipes, smaller and darker, had its grate hanging loose, one hinge shattered. Their back door.
Rosa positioned herself in the shadows cast by the junction box, her back to a curved wall. She took the radio from her belt, her thumb hovering over the transmit button. She looked down at the slice of Roy’s face she could see in her collar.He gave a tiny, sharp nod.She pressed the button. The static crackle was violent in the stagnant air.She let a ragged, terrified gasp bleed into the microphone first. Then she spoke, her voice strained, trembling with a flawless, desperate edge.
“—anyone, please, Anderson, come in! It’s Rosa. I’ve got Roy but he’s… he’s bad. Silas is… he’s done nothing to him. We’re heading for the old Chem wing drains. It’s the only place left. Please, if you can hear this…”
She released the button, cutting off the transmission. The fake echo of her own fear hung in the chemical-tainted air. She unclipped the radio and tossed it clattering across the wet floor, ten feet away, a perfect lure. Then she drew her hatchet, switched off her flashlight, and melted into the deep shadow beside the broken grate. She became a statue, her breathing slowing to a near-imperceptible whisper.
Roy felt her body temperature drop as she forced herself into a state of cold readiness.
Silence.
Then, a new sound. Not the drip of water. A soft, scraping tread from the pipe they’d entered through. Deliberate. Unhurried.
A figure resolved from the darkness, silhouetted against the distant, flickering emergency light. Silas.He looked gaunt in the sickly glow, his bald head gleaming with moisture. He held a device in one hand—a boxy, homemade thing with a dish antenna and a single, ominous red LED. In his other hand was a long, wicked-looking steel prod, its tip blackened.
He stepped into the chamber, his dark eyes scanning, skipping over the discarded radio, sweeping the shadows.He smiled, a thin crack in his pale face.
“Too easy, Rosa,” his voice echoed, dry and rasping.“The performance was a little… theatrical. But the location is admirably predictable.” He took a step toward the radio. “The rodent returns to its warren.”
He was five feet from the radio, his back to her shadow.
Rosa moved.
It wasn’t a cry or a shout. It was a silent eruption of kinetic force. She crossed the slick floor in two long, swift strides, hatchet raised for a downward strike aimed at the arm holding the prod.
Silas was faster than he looked. He didn’t turn. He dropped into a crouch and spun, the steel prod whipping around in a savage, backward arc. It caught Rosa on the thigh, a brutal, numbing blow that glanced off bone. She grunted, her strike thrown off. The hatchet bit into the concrete floor with a shower of sparks instead of his flesh.
Roy’s world became a violent whirl. He clung to the fabric as Rosa reeled back, her leg buckling. Silas was on her, a flurry of sharp, economical jabs with the prod. He fought like a scorpion—fast, precise, aiming for tendons, joints, the soft hollow behind her knee. Rosa blocked with the hatchet’s handle, the impacts jolting up her arms.
Metal clanged and sparked in the dim light.
She kicked out, her boot connecting with his sternum, driving him back a step. He coughed, a wet, nasty sound, but his smile never faded. He feinted with the prod, then lunged, not at her, but at the collar of her shirt. The blackened tip swept an inch from Roy’s face, the smell of seared metal and ozone filling his tiny world.
Rosa caught his wrist with her free hand, her fingers digging in with crushing force. For a second, they were locked, straining, his skeletal arm trembling against her raw strength. Then she head-butted him.
The crack was sickening.
Silas stumbled back, blood bursting from his nose. He dropped the prod.It clattered into the scummy water.
But he didn’t let go of the device. His thumb mashed a button.
A high-pitched whine, almost ultrasonic, filled the chamber.The red LED blazed. A visible, rippling wave of distorted air, like heat haze, erupted from the dish and shot toward Rosa.She flinched, bracing for pain. Nothing happened to her.
Behind Silas, from the dark pipe he’d emerged from, a shape shambled into the flickering light. It was a walker, what was left of a man in a tattered campus security uniform. Its jaw hung slack, one eye a milky ruin.But it wasn’t moving toward Silas. Its clouded gaze was fixed, with single-minded hunger, on Rosa’s collar.On Roy.
The distortion wave hadn’t been an attack.It had been a beacon.A scent marker.
“Observe the result,” Silas spat through the blood filling his mouth.
The walker lurched forward, its pace quickening, arms reaching.
Rosa’s choice was instant, terrible. Release Silas to deal with the walker, or finish him and let the dead thing reach Roy. Hatred and terror warred in her eyes for a microsecond. She shoved Silas violently away from her, sending him sprawling toward the rushing central grate, and turned to face the new threat.
The walker was slow, clumsy. She dodged its grab, her hatchet flashing down in a clean, brutal arc. It bit deep into the thing’s skull with a wet thunk.The walker crumpled.
But the seconds had cost them.
Roy, peering from his sanctuary, saw Silas scramble to his knees at the very edge of the dark water channel. The device had skittered from his hand, landing on the wet concrete just out of reach. Silas was bleeding, wheezing, his eyes wild with fury and fear.
He looked at the device. He looked at Rosa, who was wrenching her hatchet free from the walker’s skull. He looked at the black hole of the broken grate, his escape route.He made his decision.
With a final, venomous glare at Rosa, he shoved himself backward, over the edge of the channel, and vanished into the roaring black water below.
Rosa lunged for the device, skidding on her knees. Her fingers closed around its cold, hard casing just as a final, gurgling scream, swallowed by the torrent, echoed up from the depths.
Silence rushed back in, broken only by the dripping water and Rosa’s ragged breaths. She knelt there, clutching the device in one hand, her hatchet dripping in the other. The flickering light finally died with a fizzling pop, plunging them into utter blackness.After a long moment, her flashlight clicked on.The beam was shaky. It illuminated the dead walker, the discarded prod, the rushing grate where Silas had disappeared. She looked down at the device in her hand, its red LED now dark. She then turned the beam toward her collar.Roy looked back at her, his face pale in the harsh light. He saw the deep, ugly burn on her thigh where the prod had connected, the blood from Silas’s nose smeared across her forehead, the utter exhaustion etched into every line of her face.
“You got it,” he said quietly, his voice barely a whisper in the vast, dripping dark.
Rosa didn’t smile.She just looked from the device to the black water, then back to him. “He got away.”
“He’s gone,” Roy corrected, his engineering mind assessing the variables. “The current in those channels is ferocious. He’s either drowned or miles downstream by now.” He paused.“The device is the key. Not him.”
Rosa slowly, painfully, got to her feet.She pocketed the heavy device.She didn’t pick up the radio. She just stood in the center of the chamber, the cone of her flashlight their only world.
“We need to get back,” she said, the words hollow. “Jason… he’ll be out of his mind.”
Roy nodded, feeling the profound weight of the thing she carried. It was a victory, stained and incomplete.They had the means, perhaps, to undo what had been done. But the silence left behind by the rushing water felt less like peace and more like a drawn breath. Somewhere, in the dark, Silas was either dead or nursing a new, deeper grudge. And they were left in the stillness, holding the fragile, terrifying prize.
The fragile, terrifying prize weighed heavily in Rosa’s pocket. She took one last look at the roaring grate, the chamber now holding only the residue of violence and the dead walker. “Okay,” she breathed, the word a hollow echo.“Let’s go home.”
Exiting the sewer was a slow, agonizing process. Her thigh screamed with every step, the prod burn a raw, pulsing brand beneath her torn jeans. She climbed back into the university’s underbelly, Roy a silent witness to her labored breathing and the grimace she couldn’t fully hide. The outside air, when they finally broke into a service alley, tasted impossibly clean.It was quiet.
No rattling chains, no distorted hum from Silas’s device, no shambling footsteps. Just the wind through broken street signs and the distant call of a bird.The normalcy of it was almost shocking. Roy felt Rosa’s shoulders loosen a fraction, a tension she’d held since the S-Mart office finally beginning to drain.“You’re favoring the left,” Roy observed from her collar. His view was a narrow portrait of her jawline, slick with sweat and sewer mist. “That needs proper cleaning.Bandages.”
“I know,” she said, her voice softer now.“S-Mart first. Then home.”
The trek across town was a study in deliberate movement.Rosa didn’t run. She walked with a purposeful, measured pace, her head on a constant swivel, but the usual sprint-ready tension was gone. The silence was a third companion, and they were both extremely thankful for it. Roy watched the world pass, the scale still surreal but now almost familiar—a cracked sidewalk was a canyon, a discarded soda can a silo.He found himself cataloging resources automatically. That gutter downspout could be reforged into a conduit. Those shattered window blinds, the slats could become structural supports.His engineering mind, even shrunken and traumatized, kept working problems. The immediate problem was infection.The next problem was the device.The problem after that was Jason.
Rosa pushed open the familiar broken door of the S-Mart loading bay. The same dull gray light, the same smell of dust and decay. It felt like a lifetime since they’d huddled here planning. She moved past the rusty carts and went straight for the manager’s office, her boots leaving faint damp prints on the dusty floor.The office was as they’d left it. The faded yellow walls, the cracked desk. She knelt with a stifled groan, reaching behind the desk leg.Her fingers closed around the strap of the Medic bag. She pulled it out, the weight of it a comfort. Unzipping it, she quickly inventoried the contents: antiseptic, sterile gauze, sutures, antibiotics.The basics, but a treasure.
“Jackpot,” Roy murmured.He felt her nod, a slight movement of her neck against him.
She didn’t treat her leg there.It wasn’t safe, not really. She just shouldered the bag, its familiar weight settling next to the unknown heft of the device. She stood in the center of the empty office for a long moment, simply listening. The ghostly hum of the dead fluorescent light was gone.Only silence.
“It’s clear,” she said, more to herself than to him.“Feels… weird,” Roy admitted. “Not hearing him in our heads.”
“Don’t miss it.” Rosa’s hand came up, not to extract him, but just to cradle the spot on her collar where he rested.A simple, protective cup of her palm. It was the closest she could get to a hug.“Let’s move. Before the quiet breaks.”
She exited the S-Mart, stepping back into the afternoon light. The journey to Anderson Hall stretched before them, a gauntlet of open spaces.But they had medicine.They had the device. They had the quiet.For now, it was enough.Each step was a win. Each block placed another layer of concrete between them and the dripping dark. Roy watched the world go by, already drafting the explanation they’d have to give, already feeling the phantom pressure of Jason’s frantic, relieved embrace waiting at the end of the road.
