Chapter 7: The Roof's Sanctuary
The rooftop door hinges gave a soft, metallic sigh. Sandy emerged, squinting in the bright afternoon light, her first aid kit a familiar weight against her hip. She’d seen Rosa head up hours ago, and with the wound check overdue, the roof was the next logical place to look.The scene that greeted her was a still-life of exhaustion and peace. Rosa was sprawled on the bench, head tilted back, mouth slightly open, deep in the kind of sleep only the utterly drained manage. Her cane lay across her lap, one hand resting protectively over it even in rest.And there, in the rich, dark soil of the nearest garden bed, was Roy.
He was sitting with his back against a wooden board, knees drawn up, just staring out at the sprawling jungle of kale and oregano. He looked utterly absorbed, a tiny king surveying his chaotic, green domain. A bee, massive and buzzing, hovered near a lavender bloom right beside him, and he didn’t flinch.He watched it with the focused calm of a naturalist.
A warm fondness spread through Sandy’s chest.It was a good sight. A human sight, not a crisis one.She moved quietly, her boots making little sound on the gritty asphalt. She reached the bench and sat down carefully at the far end, not wanting to startle Rosa awake. She set the kit down with a soft click.Rosa’s breathing hitched. The sharp green eyes slid open, not with alarm, but with immediate, calculated awareness. She looked at Sandy, then past her, scanning the roof perimeter before her gaze landed on Roy in the dirt.Her shoulders relaxed.
“Hey,” Rosa murmured, her voice rough with sleep. “Check-up time?”
“If you’re done napping on the job,” Sandy said lightly, unzipping the kit. “How’s it feeling?”
“Stiff.Itchy. The good kind of itchy, I think.” Rosa carefully shifted, pulling up her pants leg to reveal the clean, stitched gash on her calf.The skin around it was pink but not inflamed. Sandy leaned in, her fingers gentle and precise.From his vantage point, Roy watched the two women.From here, they were monumental. Sandy’s ginger pigtails were thick ropes dangling like bell pulls. Her freckled hands, tending to Rosa’s leg, moved with a practiced, terrifying delicacy. He could see the individual threads in the seams of her jeans, the scuff marks on her boots like topographic maps. He felt a sudden, vertiginous surge of his own fragility. A misplaced foot from either of them…
He pushed the thought away.This was Sandy.She was careful.
Sandy finished her inspection, applying a fresh dab of salve from a tiny jar.“Healing beautifully. You’re staying off it, right?”
“Mostly,” Rosa said, which was a lie they all acknowledged.Sandy’s moss-green eyes then drifted to Roy. She smiled, a warm, crinkling expression.“And how’s our explorer? The garden look different from down there?”
Roy stood up, brushing dark soil from his pants. “It’s less ‘garden’ and more ‘uncharted wilderness.’ That lavender is a skyscraper.”
Sandy laughed, a soft, pleasant sound.“I bet.Find anything good?”
“Aphids. A whole civilization of them.They’re farming ants on the underside of a kale leaf. It’s kind of incredible.”
“See?The world’s still busy,” Sandy said, packing her kit. She hesitated, then looked at Rosa.“Lee mentioned the device. He’s… thinking about it.A lot.”
The easy warmth of the moment chilled.Rosa’s jaw tightened. “I know.”
“He’s just worried it’s a beacon. Or a bomb.” Sandy’s voice was low, practical. “We can’t just have it sitting in your pocket like a loose round.”
Roy walked toward them, the asphalt warm under his feet.The distance felt vast. “It’s not a bomb,” he called up. His voice was thin in the open air.“Its activation was specific.A tuned resonance. Silas designed it for me.”
Sandy looked down at him, her expression kind but serious. “But is it still tuned to you, Roy?Or did using it… change the settings?” She voiced the fear they all carried.
Before Roy could answer, Rosa swung her legs down, wincing only slightly. “Only one way to find out. And we’re not doing it by guessing.” She stood, testing her weight on the bad leg.“We need to look at it.Properly. In a controlled space.”
“The lab,” Sandy said, nodding. “I’ll tell Lee you’re coming down. He’ll want to set up the shielded box.” She stood, hoisting her kit.She gave Roy a last, gentle smile. “Don’t get lost in the weeds, okay?”
She turned and left, the roof door closing with a solid thud behind her. The quiet returned, but it was different now, charged.Roy looked up at Rosa. “You’re going to power it on.”
“A micro-pulse. Enough to read its field, see if it’s… seeking something.” She picked up her cane. “You don’t have to be there.”
“Yes, I do.” The statement was absolute. If the device was still tuned to him, he was the safest conduit, the logical insulator. If it wasn’t, he needed to know first.Rosa didn’t argue. She just nodded, then looked around for a way to get him to her. The bench was too high for her to scoop him up easily with her leg stiff.“Any ideas, explorer?”
Roy scanned his surroundings. A length of twine, leftover from tying tomatoes, trailed from a post near the garden bed. It was thick as a ship’s rope to him. “Give me a minute.”
He jogged back to the garden, his small form disappearing between the towering leaves.Rosa watched, leaning on her cane, a faint smirk on her face. She heard rustling, then a soft grunt of effort. A moment later, Roy emerged, dragging the end of the thick twine.It coiled behind him like a lifeline.
He brought it to the base of the bench.“Tie this around your wrist. Then lower your hand.”
Rosa raised an eyebrow but complied, looping the twine securely around her wrist. She then lowered her open hand, palm up, to the asphalt. Roy climbed on, then gave the twine a sharp tug.“Okay.Pull up slow.”
It was an improvised elevator. Rosa, using her good leg and her arm strength, carefully retracted her hand, the twine keeping it steady and level. In a few smooth seconds, Roy rose from the ground to bench height. He stepped off onto the warm wood.“Not bad,” Rosa said, untying the twine.
“Simple mechanics.” He dusted his hands off. “Let’s go see what that thing wants.”
The descent through the building felt different.The stairwell was no longer a canyon but a known route. The silence of the halls was familiar, not oppressive.The roof had done its work. He rode on Rosa’s shoulder, his hand lightly gripping her braid, feeling the determined set of her stride through his own body.They found Lee and Sandy in the old physics lab on the second floor. Lee had cleared a metal worktable and was assembling a box from interlocking panels of a weird, gray, rubbery material—scavenged radiation shielding from the medical imaging department. Wires snaked from it to an oscilloscope and a portable power unit.
“The Faraday cage-lite,” Lee said without looking up, his hands moving with quick certainty. “It should contain any EM burst, assuming the burst is within the theoretical parameters I’ve extrapolated from the components we can see.” He finally glanced at Rosa, then at Roy on her shoulder. “You’re sure about this?”
“No,” Rosa said simply. She walked to the table, set her cane down, and pulled the SR device from her pocket.It looked inert, a dull, complex pebble. She placed it inside the open box.Lee connected a final wire, then slid the last panel into place with a soft click. The device was now sealed inside a featureless gray cube. A single, clear fiber optic probe pierced the top, aimed at the device’s core.“The probe will detect any photon emission. The oscilloscope will map the field. We’re using the battery from a dead cell phone for the pulse.Minimal power.” He took a deep breath.“Ready?”
Rosa looked at Roy. He gave a single, tight nod.Lee threw a switch.A low hum filled the room. The oscilloscope’s green screen glowed to life, showing a flat, calm line.Nothing.
Then, a flicker.
The line on the scope jumped, not a spike, but a slow, sinusoidal wave, pulsing like a heartbeat. A soft, eerie blue light emanated from the seam of the box, leaking from the fiber optic cable like captured spirit. It was faint, but unmistakably alive.“It’s active,” Lee whispered, his eyes wide behind his glasses. “Low-level, self-sustaining… but it’s drawing a pattern. It’s seeking.”
Roy stared at the pulsating blue light.He felt nothing.No pull, no resonance, no dread. Just a cold, clinical observation.The wave on the scope began to change. The smooth pulses jagged, spiking erratically. The blue light from the probe flickered, then intensified, casting sharp, moving shadows on the lab’s ceiling.
“It’s not finding its target,” Sandy said, her voice tight.A new pattern emerged on the screen. The chaos resolved, not into the smooth seeking wave, but into a frantic, repetitive spike.A distress signal.A hunger ping.
Then, from somewhere deep in the building, far below them, came an answering sound.
It was a low, guttural scrape.Then a thud.Then another.
It was the sound of something heavy, something persistently mindless, knocking against a door.A basement door. A sound they’d secured, reinforced, and not heard in over a year.
The blue light in the box flared brightly, once, in perfect time with the thud.
The device wasn’t tuned to Roy anymore.
It was calling to something else.
The thudding intensified, a slow, dragging beat syncopated with the device’s piercing blue pulse.
“Turn it off!” Rosa’s command sliced through the frozen moment.Lee’s hand slapped the switch.The hum died. The light from the box vanished, plunging the lab into a deeper silence that was now filled by the relentless, wet sounds from below.They held their breath.The thudding didn’t stop. If anything, it gained purpose.“It heard,” Sandy whispered, her hand pressed to her mouth.
Jason’s voice, tight with controlled panic, crackled from the walkie-talkie on Lee’s belt. “Lee, Sandy, report.”
“We have movement in the lower stairwell. North side.” Lee fumbled for the device, his glasses askew.“It’s the device.We triggered it. It called them.”
“What?” Jason’s voice was pure static-laced fury. “Where’s Roy?”
“I’m here,” Roy said, his own voice sounding impossibly small in the tense air. He felt Rosa’s hand close around him on her shoulder, a protective cage of calloused fingers.“It’s not tuned to me anymore, Jay. It’s broadcasting.”
THEY TURN IT OFF IMMEDIATELY AND PEER DOWN THROUGH THE WINDOW
The second thud echoed, closer this time, a solid impact against heavy doors. Lee scrambled to the lab’s long, grimy windows that overlooked the north courtyard and the service entrance to the basement.He wiped a sleeve across the dust, leaving a streaked arc. Rosa joined him, moving quickly despite her leg, with Roy clinging to the fabric of her shirt. They peered down.
The courtyard, usually a still life of cracked pavement and wild grasses, was alive with wrong movement. Three figures shambled from the tree line, their gaits erratic but unerringly aimed at the basement service door. Their clothing was tattered flags, their skin a map of decay. A fourth was already at the door, its head cocked, lurching its shoulder against the metal with that terrible, rhythmic thud. They weren’t masses of frenzied infection.They were deliberate.Drawn.
“They’re converging,” Rosa said, her breath fogging the glass.“The signal… it wasn’t just a noise. It was a map.”
From their third-floor vantage, Roy saw it too.The Walkers weren’t milling. Their trajectories were converging lines, all aimed at the single point beneath them.The math was terrifyingly clear. “The basement door won’t hold four,” he said, the engineer in him calculating load, fatigue, material stress.“Not if they keep that up.”
Lee’s face was pale. “The pulse was only a few seconds. The range… how far could it have reached?”
“Far enough,” Rosa replied, her voice grim. She turned from the window, her eyes landing on the silent, gray box.“That’s not a tool. It’s a lure.” Another heavy impact reverberated through the floor joists.The thing downstairs was not giving up. It had heard the call, and the call had stopped, leaving only the memory of the source. It would keep searching.The others outside would join it. They needed a new plan, and the old ones involved bullets they couldn’t spare and risks they couldn’t take.
Roy stared at the box, then at the window, his mind racing through the schematic of their building, of pressure points and weaknesses. The quiet day was over.
The quiet day was over.
Rosa’s hand was still a protective cage around Roy. Her mind, however, was already moving, discarding options, seizing the only viable one. “Lee,” she said, her voice cutting through the low thudding. “Seal that box in the lead shielding. Now. Then meet us at the armory.”
“But the field—” Lee began, staring at his oscilloscope as if it had betrayed him.
“Is a dinner bell.” Rosa was already striding for the door, her cane tapping a furious rhythm on the linoleum. “We’re switching to crowd control. Move.”
She took the stairs two at a time, her injury forgotten in the adrenaline surge. Roy clung to her shirt, the world a violent blur of passing railings and peeling paint. The fifth-floor landing was a narrow corridor lined with repurposed professors’ offices. The last door on the left was reinforced with a steel crossbar. Rosa shouldered it open.
The air inside was cool and smelled of gun oil and dust. The makeshift armory was a relic of better-organized times. Rifles stood upright in a converted bookshelf. Ammunition boxes were stacked neatly on a desk, labeled in Sandy’s careful script. Ally and Amie were already there, pulling .22 caliber rifles from the rack. Their movements were efficient, synchronized without words.
“Report,” Rosa said, setting Roy down on the desk beside an open box of rounds.
“Four visuals from the north tree line converging on the basement service door,” Ally said, her voice calm and flat. She worked the bolt on her rifle with a smooth, practiced snick. “At least one already pounding on it. Could be more we can’t see from this angle.”
Amie slapped a magazine into her rifle. “The service door is reinforced, but the frame is concrete. It’ll splinter eventually.”
Roy stood on the desk, the cartridges around him as big as firelogs. “They’re coordinated. The signal got their attention, and the cessation didn’t scatter them. It pissed them off.” He looked at the rifles, then at the door. “We need a distraction. Split their focus.”
Jason, Lee, Sandy, and Joan burst into the room, breathing hard. Jason’s eyes found Roy instantly, scanning him for injury. The relief was momentary, washed away by the tactical reality. “Basement tunnel door is holding for now,” Jayden said, leaning against the doorframe. “But the banging’s getting louder. Sounds like more than one set of hands.”
“Because it is,” Rosa said. She began handing out rifles. “We split. Two fronts. Roof team provides overwatch and picks off any approaching from the courtyard. Ground team holds the interior choke points and deals with anything that gets through the basement door.” She tossed a rifle to Jason, who caught it against his chest. “You’re ground lead. Lee, Sandy, Joan, Jayden with you.”
Jason’s jaw worked. He wanted to argue, to be where Roy was. Roy saw it in the tight line of his shoulders. “Roof?” Jason asked, his voice tight.
“Me, Roy, Ally, Amie.” Rosa slung a canvas bag of magazines over her shoulder. “High ground, clear sight lines. We can thin the herd before they ever reach your position.”
Roy moved to the edge of the desk. “Jason.” His boyfriend’s hazel eyes snapped to him. “The door’s the weak point. Don’t brace the door. Let it fail on your terms, funnel them into the stairwell. One at a time.”
Jason absorbed this, a slow nod replacing the panic in his gaze. Roy’s engineering mind was giving him a blueprint, something to do. “Funnel them. Right.”
“Move,” Rosa ordered.
The group flowed onto the landing, a sudden press of bodies and checked weapons. Jason paused in front of Rosa, his hand darting out to squeeze her arm. “Keep him safe.”
“He’s my brother.” She met his stare, and an entire conversation passed in that look. “You keep your people safe.”
Then they were separating, the two teams pulling apart like dividing cells. Jason’s group headed down, their footsteps a fading drumroll of urgency. Rosa turned to the roof access stairs. “Ally, Amie, cover the north and east parapets. I’ve got west. Roy is my eyes.”
Ally gave a sharp nod, and she and Amie vanished through the roof door, moving with a lethal grace. Rosa looked at Roy on the desk, then at the rifle she now carried. The logistics were impossible. “How do I—”
“Your pocket,” Roy said. “The front one. On the shirt.”
She lifted him, her touch firm and careful, and placed him in the thick canvas pocket of her cargo shirt. It was a tight fit, the fabric smelling of sun and old sweat. He could feel the solid wall of her chest through it, the rapid beat of her heart. She clipped the pocket’s flap closed, leaving him a narrow gap to see out. “Don’t fall out.”
Then she was moving, bursting back out onto the roof. The afternoon light was harsher now, predatory. Ally was already prone at the north wall, rifle barrel resting on the parapet. Amie was scanning the east tree line through a small monocular.
Rosa went to the west side, unslinging her rifle. She laid down, the concrete gritty and hot against her elbows. The position pulled at her wounded leg, but she ignored it. Roy peered out from his fabric perch. The world was a stunning, terrifying panorama. He could see the whole north courtyard, the three shambling figures now closer, maybe fifty yards out. A fourth was still hammering on the heavy basement service door, its movements slow and relentless.
“Amie, anything east?” Rosa’s voice was a low vibration Roy felt more than heard.
“Clear so far. They’re all coming from the north woods. Drawn to the sound.”
“Ally?”
“Three visual, inbound. Slow but steady. Rotten Mary at twelve o’clock, Plaid Shirt at two, Skinny Jeans at ten.” Ally’s voice was a cool, detached monotone. “Wind is negligible. Distance forty yards.”
“Take the one at the door first,” Rosa said, shifting slightly, her cheek settling against the rifle stock. “Relieve the pressure on Jason’s team. Then the closest inbound.”
Roy watched, utterly still. He saw Rosa’s finger curl around the trigger. Her breathing stilled. The rifle cracked, a sharp, flat sound that echoed off the building facades. Down in the courtyard, the head of the Walker at the door snapped back. It crumpled, a puppet with cut strings, sliding down the metal door to lie still.
“Hit,” Ally confirmed. “Plaid Shirt is thirty yards. No reaction to the sound.”
Rosa’s barrel shifted a fraction. Another crack. Plaid Shirt stumbled, its knee disintegrating into a spray of dark fluid, and went down. It began crawling, undeterred, pulling itself forward with gray arms.
“Leg shot,” Rosa muttered, cycling the bolt. “Ammo’s too light.”
“Switch to headshots. Conserve,” Ally said. Her own rifle spoke, once, twice. The crawling figure and another one, ‘Skinny Jeans’, went still.
“Three down,” Amie called from the east side. “One remaining, ‘Rotten Mary,’ twenty yards and closing on the door.”
Roy watched the last figure. It was a woman, or had been. Long, stringy hair hung over what remained of a moldering blouse. It walked with a lurching, dragging gait, one foot scraping the pavement with each step. It wasn’t running at the sound of gunfire. It was walking with a dreadful purpose toward the door, toward where the signal had been.
Rosa’s rifle barked again. The thing’s shoulder jerked, but it didn’t fall. It turned its head, blank sockets seeming to scan the building facade, and let out a wet, rasping keen. Then it turned and shambled faster, not toward the door, but toward the main ground-level entrance of Anderson Hall—directly below Jason’s team.
“It changed course,” Roy said, his voice muffled by the fabric. “It knows we’re here.”
From deep within the building, a new sound erupted. Not the solitary thudding, but the sharp, concussive blast of a gunshot. Then another. Then the unmistakable, guttural chorus of snarls and shrieks echoing up the stairwell.
The basement door was breached.
