The Sphinx's Last Riddle

Margaret stood at the kitchen window, watching her cat Sphinx weave through the garden like a shadow with velvet paws. At seventy-eight, she'd learned that the best mysteries weren't the ones she'd solved during her years at the agency, but the ones that lived in the quiet corners of everyday life.

"You always were better at this than me," she whispered to the cat, who blinked slowly in that inscrutable way of his.

Forty years ago, she'd been something of a spy herself—nothing dramatic like the films, just enough cloak-and-dagger to keep interesting company at parties. Her husband Arthur had never known the half of it. He'd been too busy teaching their grandson about padel, that strange sport he'd fallen in love with during their posting in Argentina. The boy still played every Sunday, the rhythmic *thwack-thwack* of the ball against the court carrying across the park like a heartbeat.

Sphinx jumped onto the windowsill, demanding his dinner. Margaret smiled, remembering how Arthur used to say the cat was the only creature who truly understood the art of observation—watching everything, revealing nothing.

She'd spent her professional life piecing together fragments of information, yet the most profound truths had come from watching Arthur read their grandchildren bedtime stories, or the way her daughter's hands moved when she gardened, exactly like her mother's had. The sphinx had asked its riddles for millennia, but the answer was always love, wasn't it?

Margaret filled Sphinx's bowl, the ceramic clinking against the floor. Some secrets were meant to be kept, others meant to be shared. The wisdom of age was knowing the difference.

"Come on, old friend," she said to the cat. "Let's see what the evening brings."

Outside, the first stars appeared, and somewhere in the distance, someone was playing padel—the familiar sound carrying through the twilight like memory itself.
