The morning came to Mila in a way that sounded like any other morning would to someone who lived inside a room built for listening. Outside her window the city arranged itself into a thin orchestra of traffic and distant construction; inside her apartment the familiar hum of the old radiator carried a steady bass line that she had learned to ignore. She kept the small studio near the kitchen like a chapel for noise—an iron desk, two monitors with soft halos, a pair of studio speakers she trusted more than many people, and a rack of drives with labels in her precise, fighting script. Forensic audio had taught her that nothing was incidental in a recording. Nothing was too quiet to be useless.
She had a ritual about unknown media. Years of depositions and casework had taught her to treat every thumb drive like a sealed envelope from a stranger: quarantine, checksum, air-gapped machine, a clean imaging process. Curiosity never extinguished her caution, but it had evolved into a professional muscle. Today curiosity flexed and hesitated as she bent to pick up the little parcel pretending to be mail—no stamp, no return address—pushed under the door and left in the awkward space where the hallway met her threshold. It was an ordinary padded envelope, the kind couriers used when they didn't want to pay for dignity. A single USB stick lay inside, unremarkable and matte-black, the kind you could buy in bulk.
She turned it over in her palms. There was no label. No blood, no fingerprints she could feel. The envelope smelled faintly of printer toner and rain. In the kitchen, the kettle clicked and began to boil; the sound was a minor punctuation she relied on to puncture long sessions of immersion. In the pot at the center of her life—work, memory, patience—this little object felt like a pebble in a stream. It altered the current.
Artyom's key lay on the counter where he always left it, a small, quiet fact reminding her that someone else shared the apartment, that someone else lived with her habits. He was on a long case in a neighboring town, or so she told herself; he had left the night before with a passport, a travel mug, and a promise to call. There were nights she did not answer when he called, and nights she waited for him to come home. But she did not even think about him as she set the envelope on the work surface and wheeled the chair toward her isolated, offline workstation. Protocol first. Questions later.
