The Last Riddle

Marcus stood before the glass case, the stone sphinx watching him with that same inscrutable smile she'd worn for four thousand years. Behind him, the elevator cable hummed as it carried another group of tourists up to the museum's Egyptian wing.

"You gonna tell me what's wrong, or just let me guess?" Sarah's voice came from the doorway. She'd been his friend since graduate school, the one person who'd never asked him why he stayed at this failing museum when better offers came calling.

He turned away from the sphinx. "David's selling the collection. All of it."

Sarah's expression shifted from curiosity to horror. "But that's—"

"Illegal. Unethical. Everything." Marcus ran a hand through his hair. "He's been funneling money into that bull shit cryptocurrency scheme for months. I found the transfer records this morning."

The silence between them stretched thin and vibrating, like a cable about to snap.

"You're going to report him," she said, not a question.

"He's my brother."

"He's robbing graves, Marcus. Literally." She stepped closer. "And he's robbing you of the one thing you actually care about."

He looked back at the sphinx. In myth, she'd devoured anyone who couldn't solve her riddle. His riddle was simpler: how to destroy the person who'd raised him after their parents died. David had always been the protector, the one who took the falls and paid the debts.

"What happens to the sphinx?" Marcus asked quietly. "If I report him, everything gets seized. Evidence. She could sit in a warehouse for decades."

"Or she stays here," Sarah said, "where you've spent ten years teaching people that the past matters. That some things aren't for sale."

Marcus pulled the flash drive from his pocket. The evidence that could end his brother's career, their relationship, the whole complicated life they'd built together.

"She asked me a riddle once," he said, almost to himself. "When I was a kid. What walks on four legs in the morning, two at noon, three in the evening? I was seven. I didn't know the answer."

"Man," Sarah said. "That's the answer."

"Yeah." Marcus pressed the flash drive into her palm. "The answer is that we change. We become something else."

He walked toward the elevator, the cable singing its rising song. "Sometimes we have to. Even when it hurts."
