The harsh, low-frequency hum of the industrial fluorescent tubes vibrated through the metal frame of the shopping cart. It was 11:42 PM in a suburban neighborhood on the outskirts of Prague. Outside, a persistent, freezing November drizzle fell against the cracked asphalt of the near-empty parking lot. Inside the mega-supermarket—a sprawling, concrete warehouse called HyperMarket—the air was thick with the sterile scent of floor wax, bleach, and cold refrigeration units.

Elena adjusted the collar of her muted charcoal wool coat. She was thirty-four, with tired hazel eyes, dark blonde hair pulled into a severe ponytail, and a countenance hardened by six months of unending legal battles over her father’s estate. She had driven here late to avoid people, seeking the quiet solitude of empty aisles to pick up basic provisions before an early morning meeting with her notary.

The store was largely deserted, save for a few night-shift workers restocking shelves in dead silence. The visual palette of the market felt drained of warmth—cool slate greys, washed-out whites, and desaturated blues dominated the massive space.

Elena stopped her cart in Aisles 4—the dairy section. She reached out with a pale hand, her silver watch reflecting the cold overhead glare, and picked up a glass bottle of organic milk.

That was when she heard the footsteps.

They were slow, deliberate, and heavy. The rubber soles of thick work boots dragged slightly against the polished linoleum floor.

Elena didn’t turn around immediately. She checked the expiration date on the bottle, set it neatly inside her basket, and took two steps forward. Through the reflective glass of the upright freezer doors opposite her, she caught a glimpse of a silhouette standing at the end of the aisle.

A man. Tall, broad-shouldered, wearing a navy security jacket with a silver badge pinned to his chest. His name tag read Václav. He stood with his hands resting heavily on a utility belt that held a thick black torch, a ring of heavy brass keys, and a radio clip. His posture wasn’t casual; it was rigid, locked, and intently focused on her.

Elena took a breath, turned her cart around, and walked toward the dry goods section. Behind her, the heavy boot squeaks followed at a synchronized, steady pace.
