Zero approached the hotel on Orchard Road with a borrowed maintenance pass clipped to his belt, laminated, photo slightly off, name not his.

  The excuse was fragile but valid for another forty-three minutes: emergency plumbing check for a reported leak on the quarantined floors.

  Police tape criss-crossed the main entrance in neat diagonals, temporary signs in four languages directing essential personnel to the side loading bay.

  Hand-sanitizer stations stood like sentries every ten metres, pumps still glistening from recent use. The building didn’t feel abandoned; it felt compliant, waiting for the correct sequence.

  He slipped through the staff entrance. The lobby beyond the bay was dimly lit, marble floors reflecting the red glow of exit signs.

  A lone receptionist in full PPE glanced up, scanned the pass without interest, waved him toward the service lifts. Everything normal, everything permitted.

  The lift indicator flickered. Floors 12 to 18 were marked out of service with red tape across the buttons, yet the numbers glowed faintly, then went dark again.

  Zero pressed 9. The doors closed anyway.

  The lift descended one floor, stopped, doors opened on their own. Empty corridor, carpet freshly vacuumed, plastic sheeting draped across doorways like translucent curtains.

  Lights came on in sequence ahead of him, as if the motion sensors had already registered his weight.

  He stepped out. The doors closed behind him with a soft chime he hadn’t triggered.

  The geometry was wrong. Temporary walls had been erected for quarantine overflow, plywood partitions painted institutional beige, creating new angles that didn’t match the mental map he’d carried for years.

  Furniture was stacked in neat barricades: mattresses upright like shields, bedside tables forming narrow chokepoints.

  Zero turned left where memory said left should lead to the ice machine; instead he faced a dead end sealed with more plastic. He backtracked, rerouted. The corridor lights followed, polite and precise.

  He passed beneath a dome camera. It remained fixed on the spot he had just vacated. Ten steps later it tilted with a faint mechanical sigh, correcting late, as if embarrassed by its own delay.

  Zero stopped in the middle of the corridor. The air conditioning hummed at a steady volume, no variation. He understood then: he was no longer navigating the building. The building was pacing him.

  The service corridors behind the guest floors were narrower than he remembered, ceilings lower, pipes overhead wrapped in fresh insulation.

  Doors that used to swing freely now resisted, requiring shoulder pressure, as if the hinges had been adjusted overnight.

  Ventilation noise rose suddenly, a white roar that swallowed his footfalls, for a moment protective, then suspiciously convenient.

  Human proxies appeared without urgency. A cleaner in hazmat yellow pushed a cart loaded with folded linens, head down, moving with the slow inevitability of a roomba.

  The cart blocked the junction Zero needed.

  The genuine version of this novel can be found on another site. Support the author by reading it there.

  He waited; the cleaner sanitized the handle twice, methodically, before rolling forward again.

  Zero slipped past.

  Further on, a security guard stood at a T-intersection, mask pulled high, repeatedly pumping sanitizer into gloved palms.

  The guard didn’t look up, but the timing forced Zero to take the right branch instead of straight.

  He used the maintenance stair he’d relied on for years, a narrow spiral that bypassed three choke points and spat him out near the loading dock.

  The door opened on the first try.

  He descended two at a time.

  Halfway down, the lights behind him cut out floor by floor, a descending wave of darkness. He reached the bottom landing; the door ahead was already ajar. He pushed through. The stairwell lights above remained off.

  That route was burned forever.

  The compression spiked. Sound tightened into a single register, no highs, no lows, just midrange pressure. Air grew heavier, as though altitude had shifted without elevation. Every path offered compromise: left meant passing another proxy, right meant brighter lighting and more cameras, straight meant a longer exposed stretch.

  Neutral options evaporated.

  His phone vibrated hard enough to feel through the pocket. He pulled it out. A new app icon had appeared, no installation animation, no notification trail. Name: MOH_ContactTrace_v4.1.

  It opened itself, began requesting permissions he had already denied weeks ago: location always, camera access, microphone access, Bluetooth scanning.

  Each request pulsed once, politely insistent.

  Zero disabled nothing. He pocketed the phone and kept moving. Denial was now data.

  The back-of-house arteries of the connected mall were usually dead space, stock rooms, shuttered boutiques, delivery ramps never meant for customers.

  Tonight they were too clean, floors mopped to a dull sheen, emergency lighting strips glowing soft green along the baseboards.

  The lights guided him deeper instead of out.

  Pursuit became physical, not through agents but momentum. A fire door he expected to remain open began closing slower than physics allowed.

  An escalator dormant for months jerked to life just late enough to force him to jump the last three steps. Zero ran.

  He vaulted a half-dropped security gate in the service corridor linking hotel to mall. Metal scraped his back, tore fabric, left fibres behind.

  Behind him, real footsteps started, boots on concrete, two sets, unhurried but closing the delay.

  The mall backstage unfolded: loading bays with roller shutters down, staff canteens stripped of chairs, corridors lined with abandoned retail stock still in plastic wrap.

  Emergency lighting brightened ahead, dimmed behind, herding him.

  He shoulder-checked a side door into a shuttered luxury boutique; mannequins stared from the dark. He cut through, emerged into a delivery ramp sloping downward.

  A security gate ahead dropped halfway with a metallic clang. Zero slid under on his stomach, gravel biting elbows.

  The gate finished closing behind him. The footsteps stopped, confused by the new barrier.

  He triggered a fire door at the far end, handle stiff, alarm long disabled but wiring still live. A piercing bell erupted somewhere above.

  Shouts echoed distantly; staff redirected toward the noise. Zero slipped through the final exit into the public forecourt, ugly and brightly lit, tourists long gone, only delivery scooters parked in orderly rows.

  He reached open air. The chase stopped immediately. Behind him, through the glass doors, the mall’s ambient music resumed, cheerful pop at perfect volume, untouched by panic.

  Zero knew he could never use this mall again. Not because it was guarded. Because it had learned him.

  Zero leaned against a concrete pillar two blocks away, breathing hard through the mask. Minor scrapes on elbows, tear in his shirt, nothing bleeding heavily.

  Pulse still fast, but sound was slowly returning to normal order: a distant scooter backfiring, the irregular hiss of bus brakes, gulls overhead arguing over nothing.

  The burner rang.

  “Package confirmed,” Elias said. Voice flat, no acknowledgment of the chase, no apology. “Efficient route choice on the ramp exit.”

  Zero said nothing.

  “Next window opens in six hours. Coordinates incoming.”

  The line went dead.

  Zero understood now: the objective hadn’t been the sealed pouch left in the quarantined room safe. It had been observing his response under compression, how he rerouted, which exploits he burned, how long he could stay invisible when the infrastructure itself turned hostile. The pursuit had been the test.

  He checked the phone. The new app remained, icon greyed out but present. Permissions unchanged. Silent. Waiting.

  He plotted alternate routes instinctively, overhead bridges, connector ramps, void-deck shortcuts. Gaps appeared where paths used to be. Not blocked. Just simplified out of usefulness. The city’s map had updated around his habits, pruning branches he relied on.

  He got out.

  The city remembered.
