The Sphinx's Last Riddle

Arthur sat in his worn leather armchair, watching seven-year-old Lily creep across the Persian rug. She moved with exaggerated stealth, her sneakers silent, her eyes narrowed behind her grandmother's old reading glasses.

'Are you still playing secret agent?' Arthur asked, his voice raspy with affection.

'I'm a spy, Grandpa,' Lily whispered solemnly. 'I'm investigating the pyramid.'

Arthur smiled. On the coffee table sat the crystal pyramid he'd bought in Egypt forty years ago, back when he and Eleanor were young and hungry for the world. They had camped beneath desert stars, eaten street food that made them brave, and stood before the Sphinx, that ancient lion-woman with her impossible riddles.

'The Sphinx asked me something,' Arthur told Lily, setting down his tea. 'But I didn't understand the answer until I was your father's age.'

Lily abandoned her spy mission. 'What was the riddle?'

'What walks on four legs in the morning, two at noon, and three in the evening?'

Lily frowned. 'A zombie?'

Arthur laughed, a rusty sound. 'No, sweetheart. Though some days in my office, I felt like one. You know what I mean—just going through the motions, half-alive, like I was sleepwalking through my own life.' His expression softened. 'The answer is a person. We crawl as babies, walk tall as adults, and need a cane in our later years.' He tapped his wooden cane. 'Three legs.'

Lily considered this, her brow furrowed with that serious expression children wear when grappling with life's big questions.

'But Grandpa,' she said, 'you're not three-legged. You're the tallest person I know.'

Arthur felt his heart swell. 'That's what your grandmother used to say.' He lifted the crystal pyramid, watching light fracture through its facets. 'I built things, Lily. A business, a home, a family. But this pyramid here—this pyramid reminds me that what matters isn't how tall we stand, but how many people we help stand tall.'

He set it down carefully, beside his old spy camera from the days when he'd photographed Eleanor in Paris, her laughter frozen in silver gelatin. All these years later, he understood the Sphinx's real riddle: love is the only thing that doesn't age.

'Are you going to tell me another spy story?' Lily asked, climbing onto his knee.

Arthur wrapped his arms around her, inhaling the scent of childhood—sunshine and possibility. 'Oh, I've got stories,' he said. 'But first, let me tell you about the time your grandmother and I got lost in Cairo looking for the perfect coffee...'

Outside his window, the afternoon sun gilded the world. Life, Arthur thought, was its own riddle. But some answers—family, love, these moments—were worth a lifetime to find.
