Poolside Sphinx

Elena had become something she never thought she'd be: a spy in her own marriage.

It started small—checking his phone when he showered, tracking his location through that shared app they'd installed for safety, not surveillance. But tonight, swimming laps in the apartment complex pool at 2 AM, she couldn't escape what she'd learned.

The pool's centerpiece was a kitschy concrete sphinx, its face eroded from decades of chlorine and weather. Elena had always found it ridiculous. Now, floating on her back between laps, she stared up at it and wondered if it was mocking her.

"What walks on four legs in the morning, two at noon, three in the evening?" she whispered to the empty night air. The answer was man, but the real question was simpler: what was a marriage?

Her phone on the pool deck chimed—another notification from David's calendar. "Dinner with clients." Again. Three nights this week. He'd come home smelling of perfume that wasn't hers, tasting of wine she'd never bought.

Elena resumed swimming. Breaststroke, backstroke, freestyle. The rhythm was hypnotic, the water holding her like something both maternal and indifferent. She'd been an Olympic hopeful once, before the injury, before David, before everything.

The sphinx seemed to be smiling now.

"You know," she told it, treading water in the deep end. "The riddle's not about the creature. It's about what the creature becomes."

David had changed. Or maybe she had. Maybe they both had, gradually, until they were strangers who happened to share a bed and a mortgage.

Her phone chimed again. A text from David: "Coming home late. Don't wait up."

Elena swam to the pool's edge and hauled herself out, water streaming off her body like something being shed. She picked up her phone and typed three words.

"I know everything."

Then she deleted them. Instead, she wrote: "Sleeping at Sarah's tonight."

The sphinx said nothing. It didn't need to. Some riddles answered themselves.
