Spectral Circuit

Neon rain scoured the faces of Vesper's market like an acid baptism, turning storefront holograms into slick ghosts. Juno moved among them with the mechanical attention of someone who had been reading circuitry for longer than she remembered reading faces. Her jacket repelled water and cheap surveillance; the collar hid the faint scar where an older interface used to bite into her skull. Around her, the neuromart pulsed with bargain chatter: patched implants, bio-silk patches, illegal firmware flashed on the spot. Vendors—some with lopsided chrome smiles, some with night-black eyes—tugged at her hood, offering salvage, memory-wanes, fragments torn off from richer citizens and sold to keep lights on.

She wasn't there for scraps. She had a name and a dead timeline. Ren So had been a friend once, a habitual smile on the wrong side of the trenchlines; then Ren had gone quiet and the quiet had stayed. The city kept swallowing people whole and spitting out tags and rumors. Juno's hands had taught themselves to look for tags: provenance glyphs, encrypted seals, the faint ghost of a corporate imprint. That was why she was scanning each wafer, each cracked dielectric like a surgeon inspecting a rib.

The vendor who finally stopped pressing was small and quick, with a face that had been augmented too many times to be trusted. He pushed a tray across the tarpaulin, and the tray rattled with glassous slivers—memory patches that shimmered like frozen fish. One piece sat at the center, its substrate crazed with hairline fractures; a faint pulse of corrupted light leaked from within. The vendor said the right number of lies and the wrong number of truths. "Fresh enough to eat," he offered. It took everything Juno had not to roll her eyes. She flipped the patch into the reader on her wrist—a clumsy, honest device she'd kept from an old job—and watched the diagnostic bloom.

Fragments flared, then hiccuped. Most were blank noise: factory timestamps, license hashes, futile efforts at anonymization. Then the reader spat a provenance header she didn't expect: Helix Dynamics. The name was a cold weight. Helix was a cathedral of neat absolutes—behavioral models, workforce bindings, firmware locks—everything Juno had learned to distrust. She felt the market narrow, the neon turn into a corridor with cameras. The vendor's grin thinned like paper. "Hotware," he murmured, and slipped away into the crowd as if the market could forget what had just changed.

She had been a neural-interface engineer once, employed in corridors where temperature was a white glove and empathy was a compliance metric. That life left her with an ability to read a patch like scripture: how a splice had been planted, what hand had signed it, which update chain had touched its edges. Helix's glyph was precise, a corporate sigil wrapped in obfuscation, and beneath it a throwaway header that told her where the data had last checked in. A relay node in Vesper's west spine—derelict, scheduled for demolition the city promised the poor once a decade.

Juno could have walked away. Plenty did. The city taught a person to count risk like taking breaths. But something about the patch made the memory of Ren step forward from where it had crouched in her chest. She had a small blue bookmark from her childhood—an almost meaningless sound, a name-call her mother used, stored like an acoustic fingerprint she couldn't lose even when everything else emptied out of her. Her wrist reader hummed a low oscillation when it saw that bookmark embedded in the fragment's metadata. It was a stupid, private little thing. She felt that stupid thing tighten into the hinge of a decision.

She took the patch and folded it into the inner pocket of her jacket. The market dissolved behind a cascade of umbrellas and neon umbrellas. She threaded toward a signal loop and pinged Iris Vale, a user handle that had become a rumor with an address. When the connection rose, Iris's voice arrived low, calmed by habit and caffeinated with opinion. "You never call me for market tours, Juno. What did you buy?"

Juno kept her voice even. "A Helix trace. West spine node. Might be nothing." Iris's inhalation was sharp; the gearshift of concern.

"If it's Helix, it's not nothing. Meet me at the old transit relay. We see if it's a ghost or a god."
