At a dusty estate sale in Halcyon, Ohio, in the autumn of 2022, I found a music box that played a song I'd never heard—a lullaby that didn't soothe, but summoned. The box had a name scratched inside: 'For Celia, 1897.' I bought it for three dollars. That night, the music started on its own. I traced the song to a local historian, who told me about Celia Morrow, a girl who vanished from her bedroom in 1901, leaving behind only the sound of that melody, drifting from her window. The box had been sold at six different estate sales since then, each time finding its way back to a new owner just before dawn. I returned the box to the sale the next morning, but the song stayed in my head—and now, every night at 3:17, I hear it again, faintly, from somewhere inside my own house.
