Zero moved because stopping felt worse.

  The circuit breaker had emptied Singapore’s streets with surgical precision: no loitering, no gatherings, no reason to be out past ten unless you carried a permit or a lie good enough to pass a roadblock.

  The MRT entrance ahead was shuttered, metal grille pulled down like a mouth clamped shut, the glass doors behind it dark except for the standby glow of the fare gates. A single SafeEntry poster flapped in the weak breeze, QR code staring out like an unblinking eye.

  He kept to the shadow line of the overhead track, footsteps soft on the pavement. The city wasn’t abandoned, ambulances still wailed somewhere far off, a delivery rider’s scooter whined two blocks over, but the sounds arrived wrong.

  His own soles struck concrete and the echo rose sharp, then refused to fade, hanging in the air like it had forgotten how to die. A distant bus engine maintained perfect pitch, no Doppler drop as it crossed an intersection he couldn’t see.

  Zero shortened his stride; the echo shortened with him. He lengthened it; the echo stretched obediently. He did not pause to wonder why.

  He adjusted.

  Masks were supposed to help. They turned everyone into partial faces, interchangeable.

  Tonight they only made him more obvious: one figure moving where none should.

  No crowd to fold into, no elbows to match, no spilled gravy to dodge. Just him and the empty.

  He cut across the forecourt of the hawker centre.

  Chairs were stacked on tables in perfect towers, metal legs interlocked like surrendered weapons. Half the fluorescent tubes still burned, throwing cold light over wiped-down surfaces that smelled of bleach and pine instead of charred garlic and sambal.

  Zero stopped beneath the signboard for his usual nasi lemak stall.

  The silence here used to be impossible; now it was absolute, and it remembered him. He felt the old reflex, lean against the pillar, let the arguments and clattering woks swallow him whole, but there was nothing to swallow him tonight.

  As he turned to leave, the SafeEntry stand ten metres away lit up by itself.

  Screen woke, camera iris dilated, QR code brightened in invitation.

  His phone vibrated once against his thigh: Movement detected outside permitted window. He hadn’t broken stride, hadn’t come within scanning range. The message was timestamped three seconds in the future.

  Zero exhaled through the mask, breath fogging the fabric, and slipped into the service alley he’d used for years. Narrow, damp, lit only by the overflow from kitchen exhaust fans that no longer ran.

  The walls felt closer than memory allowed.

  The alley hadn’t decided what he was yet, but it was thinking about it.

  The second alert arrived before he cleared the alley.

  This one carried coordinates he hadn’t reached yet, a pin dropped on the perimeter path behind Block 147. Timestamp: four minutes from now. Zero read it once, thumb hovering, then doubled back toward the main road, testing.

  He took the long way, looping past the closed 7-Eleven, cutting through the carpark where only essential vehicles were supposed to park.

  The alert updated anyway. New pin: the exact spot he would reach if he kept this new route.

  The city wasn’t tracking. It was predicting.

  He was still processing that when the burner phone in his back pocket rang, cheap Nokia, bought for cash two weeks ago, number known to no one. He let it ring twice, then answered without speaking.

  “You’re moving inefficiently,” the voice said. Male, mid-fifties, filtered through a layer of digital gravel. Calm, almost bored.

  Zero stayed silent.

  “Left at the vending machine would have saved you forty-three seconds. But you already knew that.”

  Zero glanced up. The CCTV dome above the carpark entrance was angled away, blind spot he’d mapped himself last year. The voice continued.

  “Your contact-tracing heatmap shows a cluster seed with no contacts. That’s interesting to the wrong people. Daily swabs, mandatory quarantine, public naming. All very tiring.”

  No threat of violence. Just paperwork, procedure, visibility. The weapons of a locked-down city.

  “Alternative,” the voice said. “Coordinates incoming. Retrieve a pouch. Leave it at the next drop. No cameras, no names.”

  Zero watched a lone ambulance glide past on the main road, lights off, silent. “If I don’t go?”

  A soft exhale that might have been laughter. “You already are.”

  The line died. New message appeared: an address in a half-shuttered commercial block off Balestier, three kilometres north. Zero stared at the screen until it dimmed. Then he turned toward Balestier.

  The building was small, five storeys, the kind that housed tuition centres and small import-export offices.

  Front roller shutter down, side door ajar exactly wide enough for one person.

  Zero slipped through.

  Inside, motion sensors woke politely. Fluorescent tubes flickered on one row at a time, guiding him down the corridor like a polite usher. He kept his shoulders rounded, walk unhurried, posture copied from the essential-worker posters plastered everywhere: purposeful, compliant, permitted.

  Lift doors opened before he pressed the button.

  Fourth floor.

  He stepped out into a narrow hallway lined with frosted glass doors.

  Third office on the left was unlocked. Inside: overturned chairs, a desk swept clear except for a black nylon pouch the size of a paperback.

  Still warm, as if someone had just set it down.

  No electronics inside, soft give when he pressed it. He didn’t open it.

  On the way out his phone battery dropped eight percent in thirty seconds. Screen brightened with a Covid alert he’d never seen before: Stay home. No ministry logo, no reference number. Just the words, white on red.

  He reached the side door. It remained ajar until his fingers touched the handle, then closed gently behind him with a pneumatic sigh. The lock clicked once he was already clear.

  The underpass beneath the expressway was usually loud, traffic overhead, water dripping from expansion joints, the constant rattle of ventilation. Tonight every sound arrived slightly late.

  A drip hit the concrete a half-beat after he saw it fall. Tyre noise from above lagged, as if the cars were driving through memory. Zero sped up; the lag shortened. He slowed; it lengthened. The world was syncing to him instead of the other way round.

  “That’s new,” he muttered, voice muffled by the mask. He regretted saying it out loud immediately.

  The burner rang again.

  “Pouch received,” the voice said. No congratulations, no further instructions.

  Zero kept walking. He understood now: the pouch had been secondary.

  The job had required him to move through those exact corridors, those exact blind spots, at that exact pace.

  Calibration data.

  He stopped for half a second beneath the sodium lamp.

  Every delayed sound caught up at once, then waited with him.

  Zero didn’t speak agreement into the phone.

  He simply changed direction, heading toward the new coordinates that had already appeared.

  Alerts stopped coming.

  Overhead traffic resumed its normal imperfect roar. The city relaxed its grip, not forgiveness, just satisfaction.

  One route he used nightly, the footpath behind the wet market, now felt wrong in the way a familiar song played in the wrong key feels wrong. Not blocked. Just unusable.

  The voice returned one last time.

  “We’ll keep you moving.”

  Not a promise. A statement.

  Zero reached the edge of the permitted movement zone where night-shift workers from the nearby factory were starting to appear, masked, distanced, eyes down. Fewer than before the breaker, but enough. He matched their pace, their slump, their silence.

  Enough to hide, for now.

  This wasn’t recruitment.

  It was the city learning how to follow him.
