Supplements and Secrets

Maya found the bottle in his toiletry bag, tucked behind the shaving cream. Vitamin D3, 5000 IU. David never took vitamins. He made fun of her drawer full of supplements, called them expensive urine. Yet here it was.

They were in Cabo, at a resort with palm trees swaying over a private beach. A second honeymoon, he'd called it, though they'd only been married three years. Somewhere between the wedding and now, something had calcified between them. Not hardened, precisely—just become still.

She held the bottle in her palm, the plastic warm from the sun streaming through the bathroom window. He'd been acting strange lately. Distracted. Checking his phone at dinner, smiling at notifications he wouldn't share. Working late when his job as a mid-level accountant didn't require it.

Maya had always been too observant for her own good. It was what made her good at her job—user research, pattern recognition, noticing what people didn't say. And lately, David wasn't saying much.

The vitamins were a clue. Vitamin D was for people who didn't get enough sun. David played tennis every Sunday. He ran in the mornings. He was outside constantly.

Unless he wasn't.

She remembered the canceled tennis matches. The morning runs that somehow never happened. The vague explanations about feeling tired. And now, secret vitamins for a deficiency he shouldn't have.

Maya set the bottle back exactly where she'd found it. That afternoon, by the pool, she watched him. Really watched him. The way he checked his phone every three minutes. The way his thumb hovered over the screen before he tucked it away when she approached. The lie about having a headache when she suggested they go for a walk on the beach at sunset.

That night, after he fell asleep, she did something she'd never done before. She unlocked his phone with the code she'd known since they shared a Netflix account, and she scrolled.

There was no other woman. No affair. No secret gambling addiction, no hidden debts.

Instead, she found a folder of screenshots. Articles about early-onset Alzheimer's. Research papers about genetic markers. A chat with a neurologist at a clinic in Switzerland. The vitamin D was for the clinical trial he was trying to qualify for—the one that required participants to have specific biomarkers, including low vitamin D levels. He'd been avoiding the sun for months.

Maya lay in the dark, his breathing steady beside her, and understood: he wasn't pulling away from her. He was trying to protect her from the worst before it even happened. He was gathering intelligence, running his own private operation, being his own spy against a future he'd seen in his father's decline and now feared in his own.

She curled her hand around his, palm to palm, and watched him sleep until dawn.
