The Last Riddle

Elena pressed her forehead against the cold glass of the thirty-second floor, watching lightning fracture the Seattle sky. Each flash illuminated the empty office behind her—rows of abandoned desks, the ghostly glow of standby monitors. At forty-two, she'd become something she swore she'd never be: obsolete.

"You're still here?" The voice came from the doorway. Fox. That's what everyone called Julian—lean, quick, smiling with teeth that never seemed to show his gums. He'd been twenty-six when Elena hired him. Now he was thirty-two and her replacement.

"Just finishing the documentation," she said, not turning around. "For Sphinx."

"Sphinx doesn't need documentation, Elena." Julian stepped closer. She could see his reflection in the glass—tailored suit, calm expression, the confidence of a man who knows he's won. "It learns from patterns. It doesn't read manuals."

Outside, a fox darted across the rain-slicked street below—a real one, orange fur matted with rain, moving with desperate purpose toward some unknown destination. Elena watched it vanish into an alley.

"The riddle," she said quietly, finally turning to face him. "You know the one. What walks on four legs in the morning, two at noon, three in the evening."

Julian frowned. "Man. Crawls as a baby, walks as an adult, uses a cane in old age. That's the Sphinx's riddle. From mythology."

"No. The real riddle is different now." Elena gestured at the dark screens around them. "What has four legs in the morning, two at noon, and zero in the evening—because by then, something faster and cheaper does the walking?"

Julian's smile faltered.

"Sphinx solved it," she continued. "The answer is: us. The lightning development cycles, the sprints, the endless pivots—they were just preparing us for this moment. For you to take my seat, and for something else to take yours in five years."

"Elena—"

"I'm not angry, Julian. I'm just..." She looked at the empty spot where the fox had disappeared. "I'm just wondering what the next riddle is. And whether whoever solves it will even notice they were asked."
