The Riddle at Midnight

The vitamin D supplement sat on Mara's desk like an accusation. Three months since Arthur disappeared, and still his apartment remained frozen in time—half-eaten yogurt in the fridge, a copy of *The Seven Pillars of Wisdom* splayed on the nightstand, and this bottle of pills, his daily ritual for the bone-deep weariness they'd both carried like a second skin.

Mara had been Arthur's handler at the agency, but she'd also been his friend—the kind forged in safe houses and midnight stakeouts, in the way two people recognize something broken in each other and choose not to look away. Now she was a spy without a source, hunting through the ruins of a life she'd helped create.

The pharmaceutical conglomerate Arthur had infiltrated—Aethelgard Pharmaceuticals—had burrowed into his brain. He'd started talking about the new vitamin supplement they'd developed, something that promised to cure existential dread. "It's like being awake for the first time," he'd written in his last encrypted message. Then: silence.

Mara traced the bottle's label with her thumb. *Luminex — Feel Everything.*

That night, she broke into Aethelgard's research facility. The security was laughable—either arrogance or indifference. She found what she was looking for in Lab 7: clinical trial records that had been buried deep enough to never see the light of FOIA requests.

The subjects weren't experiencing enlightenment. They were experiencing something else entirely—perfect emotional pliability, a chemically induced state where the line between desire and command had dissolved. The company hadn't created a vitamin for wellness. They'd engineered a consent override.

And Arthur had been Patient Zero.

She found him in the employee cafeteria, eating a sandwich with mechanical precision. He looked the same—the same crinkling at the corners of his eyes when he saw her, the same slight stoop to his shoulders. But when she called his name, something else looked back through those familiar eyes.

"Mara," he said, and his voice was a stranger's voice using Arthur's vocal cords. "We've been expecting you."

Later, she would understand this was how it happened—not with apocalypse or catastrophe, but quietly, molecule by molecule, while everyone was looking the other way. People didn't become monsters. They became something worse: they became themselves, perfected and hollowed out, walking through their lives like zombies who didn't know they were dead.

That night, sitting in her car outside Aethelgard's glass towers, Mara finally understood the riddle Arthur had left behind in his final report: *The sphinx eats those who cannot answer, but the true horror isn't the wrong answer—it's having no question left to ask.*

She swallowed Arthur's vitamin D pill—dry, without water—and waited to see if she'd feel anything at all.
