Vitamin Z

The fluorescent lights hummed their usual headache-inducing frequency. Elena swallowed her vitamin D supplement — the only thing keeping her sane in this windowless office — and adjusted her name badge. She'd been working at BioSynth for six months, but her friend from college still thought she was in pharmaceutical sales.

The truth was more complicated. Elena was a spy, planted by Aether Corp to steal the formula for Project Renaissance. The problem was, she'd actually started liking her team. Marcus, the lead researcher, brought in goldfish for the office tank every three months, replacing them before they outgrew their prison. "Three-second memories," he'd joke, "sometimes I wish I had that after our Monday meetings."

She watched him now, eyes bloodshot from another 14-hour day, shuffling toward the coffee machine like the zombie they all became during crunch week. His lab coat was stained, his posture permanently curved from microscope hunch. Extraction was tomorrow. The USB drive with the stolen formula burned in her pocket, heavy with a guilt that tasted metallic.

Marcus looked up, catching her gaze. "You okay, El? You look pale. Maybe you need a vitamin boost."

"Just tired," she said, the lie familiar as a worn coat.

He poured her coffee anyway. "Sarah mentioned you're leaving. Found something better?"

She almost told him everything — how she'd been sent to destroy their work, how their conversations about his dead wife had become the only real thing in her life, how she'd fallen in love with a man she'd betrayed. Instead, she nodded, pressing the flash drive deeper into her pocket.

The goldfish swam endless circles in their tank, unaware of the walls that contained them. Some prisons, Elena realized, were made of glass, not bars. She'd stolen the formula, yes. But Marcus had stolen something far more valuable — her belief that she was anything other than another creature swimming in circles, forgetting she was captive.

"Yeah," she said, voice steady. "Something better."
