Chapter 25: The Garden's Memory
The cold up on the roof was a sharp, clean thing, not like the damp chill of the tunnels. Two days after the battery run, Rosa found herself up there again, tending quietly to the frosted garden beds while she tried to clear her head.
Her hands worked on autopilot, pulling up the blackened skeletons of bean vines, crumbling the dead leaves between her fingers. The soil was hard and unforgiving. Every scrape of her trowel echoed dully in the vast, grey silence. She kept glancing at the northern roofline, her eyes tracing the path where that tall, staring figure had stood. Nothing there now but chipped concrete and a few stubborn pigeons.
The roof door clanged softly, and she didn’t jump. She’d heard the footsteps on the stairs. Roy joined her some time later, Jason dropped him off before he went for a run through the tunnels: just something to work off the anxious jitters. Rosa felt the familiar, minute weight as Roy climbed up, his tiny movements precise against her neck. He immediately attached the ring in her tiny braid to his harness and tucked himself into the high collar of her shirt, his little form a spot of warmth against her skin. “Hey,” she said, her voice low.
“Hey. Jason’s pacing. Drove me nuts.” Roy’s voice was a murmur near her ear. He shifted, getting comfortable. “He says the silence is worse than the noise.”
“He’s not wrong.”
She went back to digging, the rhythm of it steadying. Roy was quiet for a long while, just watching the methodical ruin of the old plants, the careful collection of any remaining seed pods. “You remember the day we moved in here?” he asked finally.
Her trowel stilled. She let out a breath that fogged in the air. “Yeah. I remember.”
It wasn’t a happy memory. It was panic, pure and simple. The stampede of bodies down the dorm hallway, the stench of sweat and fear, the way they’d barricaded that main door with a vending machine Lee and Jason somehow toppled. They’d huddled in the dark that first night, listening to the screams outside fade into something worse: a thick, hungry silence punctuated by dragging footsteps and wet, tearing sounds.
“We were just kids playing house,” Rosa said, her voice rougher than she intended. She scraped at a root stubbornly clinging to the cold earth.
Roy shifted, and she felt the faint pressure of his small hand against the edge of her jaw. A grounding touch. “We grew up fast.”
Rosa turned her head just slightly, looking down at where he was nestled in her collar. His serious face, the dark eyes that saw too much, stared back up at her. “Yeah,” she whispered. “We did.”
A fragile quiet settled between them, the garden a testament to everything they’d built and lost. She thought about the batteries, now secured in the basement storage Lee had retrofitted. A win. But it felt hollow with the phantom of that watching man still hanging in the air.
“He’s still out there,” Roy said, as if reading the track of her thoughts. “The fly.”
“I know.”
“Sandy’s running the perimeter scans every hour. Lee’s adding a third motion sensor array on the north side, using parts from the old chem lab detectors. Jayden and Joan are checking all the window seals on the upper floors. Being productive.”
“Anxious,” Roy corrected. “We’re all anxious. You most of all.”
Rosa didn’t deny it. She attacked another dead plant, the brittle stems snapping with a sound like little bones breaking. “I don’t like being watched. It’s predatory. It means he’s thinking, not just reacting. That’s a different kind of problem.”
Before Roy could answer, the roof door opened again. It was Sandy, wrapped in a thick sweater, her tablet glowing in her hands. Her face was pale.
“Hey,” Sandy said, her voice tight. “Sorry to interrupt the… farming.”
“What’s wrong?” Rosa asked, standing up, wiping her dirty hands on her pants.
Sandy looked at the tablet, then out towards the city. “The motion sensors. The ones on the old plating facility roof, near where… you know.”
“Where I saw him,” Rosa finished.
“Yeah. They just triggered. A single, isolated movement. It crossed the western edge of the grid and then stopped.” Sandy swallowed. “It’s not an animal pattern. It’s a person pattern. Hesitating. Then holding position.”
The quiet of the rooftop garden vanished, replaced by a different kind of silence. It was the silence of a held breath, of a finger resting on a trigger.
Rosa looked north, towards the plating facility, though it was hidden behind other, taller ruins. The figure wasn’t just a fly on the wall anymore. It was a scout. And it was back.
“Tell Jason to cut his run short,” Rosa said, her voice low and flat. “Get everyone inside. Now. We're going into blackout.”
The words hung in the cold air, a stark command that shattered the fragile quiet. Rosa was already moving, her gardening tools abandoned in the dirt as she strode toward the roof door. Sandy fell into step beside her, fingers flying across her tablet to send the alert.
"Blackout protocol, everyone to common areas now," Sandy murmured into her comms, her voice echoing the order through the building's internal network.
Rosa felt Roy's tiny hand press firmly against the side of her neck, a point of focused calm amidst the sudden adrenaline. "Maintenance stairs," he murmured into her ear, his voice low and steady. "Faster, and we can secure the third-floor landing door on our way down."
They plunged into the dim concrete stairwell, their footsteps echoing too loudly in the enclosed space. Below, they could hear other doors opening and closing, the urgent shuffle of their group converging. Jason's voice crackled over the comms, breathless from his run. "I'm at the science building service door. Jayden's with me. We're locking it down from the outside."
"Confirm, then get back here," Rosa said, taking the stairs two at a time.
The third-floor hallway was a sudden flurry of controlled chaos. Lee was already at the main reinforced door, throwing the heavy new bolts he'd installed last week. His movements were efficient, his face a mask of concentration. "Ally's securing the roof access from the inside," he said without looking up. "Amie's checking the window bars on the north side.
"Good." Rosa swept past him, heading for the common room.
Inside, the mood was tense but silent. Sandy went straight to the monitoring station, her screens flickering to life with feeds from the exterior sensors. Joan was methodically checking the seals on the thick plastic sheeting over the broken west-facing window. The usual hum of the backup battery system seemed louder in the quiet.
Rosa felt her pulse hammering in her throat, a dry, metallic taste in her mouth. She forced a slow breath, focusing on the solid, quiet weight of Roy in her collar. His presence was an anchor, a tether to the practical, problem-solving part of her brain that she needed right now.
"Okay," she said, her voice cutting through the room. "Status. Sandy?"
"The initial trigger was isolated. No further movement on the perimeter grid for three minutes," Sandy reported, her eyes glued to the thermal overlay on her screen. "But the pattern was identical to before. A deliberate approach, then a halt."
Lee straightened up from the door, wiping his hands on his pants."He's testing. Seeing if we noticed, seeing how we react."
"That's what I'd do," Roy's voice piped up from Rosa's collar, small but clear in the hush. Everyone's eyes flickered to Rosa's shoulder. "If I were scouting a defended position, I'd probe the edges first. A single sensor trigger could be an animal. Our full lockdown tells him it's not."
The logic was cold and undeniable. A heavy silence descended. They had just confirmed to the watcher that they were here, that they were organized, and that they were afraid.
The main door clicked open, and Jason slipped in, followed closely by Jayden. Both were flushed, their jackets damp with a fine mist from outside. Jason's eyes found Rosa immediately, scanning her for tension before he nodded. "Science building is sealed. The livestock are secure. No signs of attempted entry."
Jayden dumped her pack by the door, her knife still in her hand. "He's herding us," she said bluntly. "Keeping us pinned inside. If he's alone, that's just creepy. If he's not..."
She didn't finish the thought. She didn't need to. The possibility of other people, alive and coordinated, was a terror far more complex than the walking dead outside. People could plan. People could wait.
Rosa crossed her arms, feeling the strain in her shoulders.
Roy shifted against her skin. "So we plan back," Roy whispered, the words for her alone. "We use what he's given us."
"Lee," Rosa said, turning to him. "That motion sensor grid on the plating facility. Can we make it talk to us more? Differentiate between a single probe and a group movement?"
Lee adjusted his glasses, his mind already working. "Maybe. The old chem lab... there are components. I'd need to retrieve them."
"Not now," Jason interjected, his voice firm. "Not while he's out there watching our doors."
"He already knows we're here," Rosa countered. "But he doesn't know what we can do. We stop reacting like prey. We start gathering information on him."
The shift in the room was subtle but immediate. The fear was still there, a cold stone in everyone's gut, but it was being slowly overlaid by a sharper, more focused energy. A problem to solve. Roy's practical mindset, channeled through Rosa, was doing its work. "Sandy, keep monitoring. Full spectrum. I want to know if a pigeon farts on that roof," Rosa said, a sliver of her old sharpness returning. "Jason, Jayden—I want a complete inventory of our defensive points, anything that's degraded. No projects, just assessment."
The group dispersed with quiet purpose, the initial urgency hardening into a determined rhythm. Rosa walked to the window, peering through a narrow gap in the plastic sheeting at the grey, blurred world outside. The figure was out there somewhere, a ghost in the ruins.
She felt a minute adjustment in her collar as Roy settled more comfortably, his small form a steady warmth against the chill seeping through the glass. He said nothing. He didn't need to. His silent presence was the leash on her anxiety, the reminder that they had built this, that they had survived worse than a pair of watching eyes. Now they just had to prove it, to themselves and to the ghost outside.
Now they just had to prove it, to themselves and to the ghost outside. The next seventy-two hours became a meticulous, nerve-fraying exercise in silent preparation. Lee and Sandy, hunched over wiring diagrams salvaged from the physics department, expanded the motion sensor grid into a subtle, overlapping web. Jason and Jayden reinforced the main door with a second, internal barricade of welded steel pipes that could be slid into place in under thirty seconds. The heavy thud of a malley ramp—an amalgamation of spears to ward off a moving car—was set against the smaller service entrance.
Watch schedules were changed from two to three people on guard at all times. Every watch stand, from the roof to the ground-floor peek-holes, now held a rifle, a sidearm, and a malee weapon within immediate reach. Defensive measures were surd up, offensive mechanisms were maintained. It was a tangible shift in the air, a quieting of casual banter replaced by the soft click of a safety check, the efficient exchange of a thermos on the roof in the predawn chill.
And Roy, tucked in Rosa’s collar or Jason’s shirt pocket, leashed Rosa’s temper and anxiety before she did something stupid. He did it not with words, but with presence. When she’d stare too long at the northern rooftops, her knuckles white on a rifle stock, he’d shift his weight, a tiny, deliberate pressure against her skin. It was a silent question: Are you seeing a threat, or are you just angry it’s there? She’d blink, breathe, and resume her scan.
On the third night, the tension found a different outlet. The common room was dim, lit by a single low-power LED strip. Jason was meticulously cleaning his pistol on a rag, the scent of solvent sharp in the still air. Lee was fidgeting with a disassembled sensor node, its circuits glowing faintly green in his hands.
“This is worse than waiting for finals,” Sandy muttered, her head resting against Lee’s shoulder.She was tracing idle patterns on his knee.
“At least finals ended,” Jason said, not looking up. He cycled the slide of his pistol with a smooth, practiced chunk-clack. “This just feels like one long, terrible pop quiz where the professor keeps staring at you.”
From Rosa’s collar, Roy’s small voice chimed in. “Professor’s probably cold, hungry, and wondering if we have better snacks.”
A short, genuine laugh escaped Jayden, who was sharpening her knife by the window. “He can wonder. Our bean harvest was pathetic and the last of the honey’s for tea only. He’d be disappointed.”
“Maybe he’s a vegan,” Lee offered, deadpan, squinting at a resistor.The lightness was brittle, but it was real.It was them. Rosa, who had been taut as a bowstring, felt a slight unraveling in her chest. She leaned her head back against the wall, feeling Roy adjust his perch. “If he’s a vegan, he’s out of luck. Joan’s goats are more defensive than Jayden.”
“Hey,” Jayden said, without heat.
A soft, periodic beep echoed from Sandy’s tablet on the table.It was the sound of the sensor grid’s heartbeat, a confirmation of operation. For a while, the only sounds were that beep, the scrape of Jayden’s stone, and the rustle of Jason’s rag.Then the beep stuttered.
It didn’t change pitch or trigger an alarm. It just skipped, a single, hiccupping silence where a sound should have been. Every person in the room froze in mid-motion. Lee’s head snapped up. Sandy was already reaching for the tablet.
“What was that?” Jason asked, his voice low.
“Grid pulse interrupted,” Sandy whispered, her fingers flying. “For one half-second. Northwestern sector, the new array by the old substation.”
“Malfunction?” Rosa asked, her voice carefully flat.She felt Roy go perfectly still.
Lee shook his head, his eyes wide behind his glasses. “It’s daisy-chained. A malfunction would cause a cascade dropout. This was local. A very specific, very brief block of the signal.”
“Like someone passed through the infrared beam,” Roy said quietly. “Just for a step.”
The ghost had moved. Not to attack, not to peer in a window. Just to stretch his legs, to remind them he could. The message was as clear as the resumed, steady beep that now sounded infinitely more sinister.I’m still here.I’m testing your fences.
Rosa stood up, the decision solidifying in her gut, cold and clear. “We’re not waiting for the next quiz question.” She looked at Sandy. “Can you trace the direction? The vector of that interruption?”
Sandy nodded, her face pale but set. “It was a east-to-west traverse. Quick. He was moving laterally across our northern view.”
“Right. Then tomorrow, at first light, we don’t just watch.” Rosa’s gaze swept the room, landing on Jason, then Jayden. “We draw a line. We go out there, to that substation, and we see what he left behind. A footprint, a scrap, anything. We take a piece of his mystery back.”
Jason met her eyes, a slow, grim understanding dawning in his. It was a risk.It was potentially playing right into the watcher’s hands. But the alternative was to sit and let the silence and the periodic, teasing beep slowly drive them all to a mistake.
Roy’s hand pressed against her neck, not to restrain, but to affirm. It was a dangerous plan, born of a temper he usually kept leashed.But this wasn’t reckless anger. It was calculated reclamation.They would stop being the watched. They would, for one morning, become the seekers.
The beep continued its regular pulse, a metronome counting down the hours until dawn.
The beep continued its regular pulse, a metronome counting down the hours until dawn.
Rosa took first watch again, Roy curled up against her neck, his harness attached to the tiny, sturdy braid behind her ear. The rooftop was a vault of frozen blackness, the city below a silent, jagged silhouette against a sky devoid of moon or stars. She scanned the northern darkness where the substation hunched, her gloved fingers resting on the cold stock of her rifle.
Every sense was pitched to a raw edge. The wind carried the scent of old concrete and the distant, sweet-rot smell from the river flats. She heard the faint scrabble of a rodent in the garden debris, the groan of a distant metal beam settling. Normal sounds. Her mind dissected each one, filing it away as non-threat. Roy was a warm, breathing weight, his stillness absolute. He wasn’t sleeping. She could feel the focused alertness in his tiny form, a companion in the vigil.
“He’s patient,” Roy’s whisper was barely a vibration against her skin.
“Or he’s gone,” Rosa murmured back, her breath a pale cloud. “The signal skip could have been a frayed wire. A bird.”
“You don’t believe that.”
“No.” She didn’t. Belief was a luxury their world had stripped away, leaving only the cold calculus of pattern and probability. The pattern said the skip was a footstep. “Lee’s design is solid. A bird wouldn’t block it that cleanly.”
They lapsed back into silence. The horizon began to smudge from black to a deep, bruised grey. Shapes emerged from the gloom: the skeletal outline of the greenhouse, the jagged teeth of broken ventilation units. The shift change would come soon. Jason would arrive, smelling of sleep and earnest concern, and she would pretend the watch had been quiet.
A new sound registered. Not from the north. From below. The soft, definitive snick of the rooftop access door being unbolted from the inside.
Rosa didn’t turn. Her finger slid inside the trigger guard. Roy pressed himself flatter against her neck. The door swung open with a sigh of rust, and a tall, lean figure emerged, moving with a familiar, quiet grace.
“Just me,” Jason’s voice came, low and soft. He crossed the gravel to her post, a thermos in one hand. “Couldn’t sleep. Thought you might want some tea before the circus starts.” He unscrewed the cap, and the scent of bitter herbs steamed into the cold air.
She accepted the thermos cup, the heat searing through her gloves. “Circus?”
“The grand expedition. The walk to the probably-booby-trapped substation.” He tried for lightness, but it fell flat, strained at the edges. He stood close, his shoulder nearly touching hers, his gaze also fixed on the north. “Lee’s downstairs trying to solder a proximity alarm to a walkie-talkie. Jayden’s sharpening things that don’t need sharpening. It’s... festive.”
Rosa took a sip, the liquid burning a path down her throat. “We have to do something.”
“I know.” He bumped her shoulder gently. “I’m not arguing. Just… be more careful than you usually are. Which is already a lot. So be paranoid.”
“I’m always paranoid.”
“See? You’re halfway there.” He took the cup back, his fingers brushing hers. “I’ll take the watch. Go down. Get some fuel. Be the intimidating leader everyone needs.”
She hesitated, the instinct to stay, to keep her own eyes on the threat, warring with the logic of conservation. Roy shifted. “He’s right,” he whispered, for her alone. “You need to be sharp for the walk. I’ll stay up here with Jason.”
That decided it. She nodded, passing the rifle to Jason. Their hands lingered on the transfer, a wordless exchange of responsibility and fear. “Anything moves, you call. Don’t be a hero.”
“My hero days are scheduled for Tuesdays,” he said, managing a real, if tired, smile. “This is Thursday. I’m strictly observational.”
She left him there, a solitary sentinel against the growing light, and descended into the belly of the hall. The common room was as Jason described: a workshop of quiet, focused anxiety. Lee hunched over a circuit board, a magnifying headset strapped to his forehead, the smell of hot solder in the air. Jayden was, indeed, running a stone along the already-razor edge of her hunting knife with rhythmic, obsessive strokes.
Sandy looked up from her tablet, her eyes shadowed. “All quiet on the electronic front. For now.”
“Good.” Rosa went to the supplies locker, pulling out a heavy canvas pack. She began methodically loading it: water, basic med kit, bolt cutters, a handful of protein bars that tasted like salted sawdust. Her movements were automatic, a ritual of preparation.
Amie entered silently, his crossbow in hand, a quiver of bolts slung over his shoulder. He gave her a tight nod, then went to check the fletching on each bolt, his long fingers moving with meticulous care. His quiet was a different texture than the room’s tense buzz; it was a deep, swallowing stillness.
By the time the proper grey dawn light filtered through the plastic-covered windows, they were assembled. Rosa, Jayden, and Amie would go. Jason would man the watch with Roy. Lee and Sandy would monitor the sensors, their voices a direct line in Rosa’s ear.
“Standard retrieval protocol,” Rosa said, her voice cutting through the thick air. “In and out. We look for signs, not a fight. Amie, you’re on point perception. Jayden, rear guard. Anything feels off, we retreat immediately. No debate.”
Jayden hefted her pack. “What exactly are we looking for? A calling card?”
“A mistake,” Rosa said, zipping her jacket up to her chin. “A scuff mark, a thread, a piss spot against a wall. Something that tells us he’s a man, not a ghost. Men have needs. Men leave traces.”
Roy, now secured in Jason’s shirt pocket, spoke up. “The sensor he crossed is on a catwalk at the substation’s southwest corner. Focus there. Look for disturbances in the rust, anything on the grating.”
Jason’s hand hovered over his pocket, a protective gesture. “Bring our guy back in one piece, okay?” he said, his eyes on Rosa.
She met his gaze, a thousand unspoken words passing between them in the space of a breath. “That’s the plan.” She turned to the door. Lee slid the final bolt back with a solid thunk.
The corridor outside was a crypt of shadows and stale air. They moved in a practiced triangle, Amie gliding ahead, his head constantly swiveling, Rosa in the center, Jayden a few paces back, her head cocked to listen behind them. The journey to the service door was a familiar gauntlet of echoing footsteps and pooled darkness.
Then the door was open, and the outside world rushed in: cold, bright, and terrifyingly vast. The silence was immense, broken only by the distant, lonely cry of a crow. They slipped out, one by one, into the long, deep shadows of morning, the door clicking shut behind them with a sound of finality.
Their path took them through a shattered courtyard, across a street littered with the fossilized remains of cars, and into the alley network that skirted the old plating facility. The substation emerged ahead, a fenced compound of yellowing concrete and dead transformers. The catwalk Roy mentioned was a rusty lacework against the grey sky.
Amie held up a fist at the compound’s blown-open gate. He pointed. In the dew-dusted mud just inside the fence, clear as a stamp, was a single, fresh footprint. It was large, wearing a heavy tread pattern, and it pointed inward.
It hadn’t been there three days ago.
Rosa’s heart hammered against her ribs. He had come down. He had walked here, right up to the threshold. She keyed her comms, her voice a dry whisper. “We have confirmation. He was here. On the ground. Proceeding to the sensor point.”
Sandy’s voice crackled back, tight. “Copy. No movement on other sectors. You’re clear.”
They moved inside the fence, the air tasting of ozone and decay. Amie led them to a rusted ladder bolted to the side of the main structure. He went up first, crossbow slung, his movements silent. Rosa followed, the cold metal biting through her gloves.
The catwalk groaned under their weight. The sensor Lee had placed was a small, grey box tucked near a support beam, its tiny LED blinking a steady green. Rosa crouched beside it, Jayden covering the perimeter.
And there it was. On the grating, directly in the infrared beam’s path, was a smudge. Not dirt. Something darker, viscous. Rosa leaned closer, her nose wrinkling. It was a dried spatter of blood. A few inches away, caught in the rusted teeth of the grate, was a single strand of thick, dark wool fiber.
He hadn’t just passed through. He’d stopped here, maybe leaned against the beam. He’d been injured, or had injured something else. And he’d shed a piece of his clothing.
“Got it,” she breathed into the comms. She carefully pried the fiber loose with the tip of her knife, sealing it in a small plastic bag from her kit. She took a picture of the blood smudge with a small digital camera, the flash blinding in the dim space. Evidence. A piece of his mystery.
A sudden, sharp crack echoed from the east, the sound of splitting timber. All three of them froze.
It wasn’t a walker. Walkers didn’t break things that cleanly.
It came from the direction of Anderson Hall.
