The old mission of San Esteban had been on my list for years. Perched on a dusty hill above the dried-up riverbed, it was a skeleton of adobe and timber, its bell tower a hollow finger against the relentless Arizona sun. I’d visited five times, always in the forgiving light of early morning, and each time I left with nothing more than a sense of historical melancholy. But the sixth visit, I made in the late afternoon, when the long shadows painted the desert in shades of amber and bruised purple.
I wandered past the crumbling sanctuary and into the fenced graveyard, a patch of stubborn grass and tilted headstones. The air was still, the only sound the whisper of dry grass and the distant screech of a hawk. Then, a soft thud near my feet. I looked down, expecting a fallen branch or a piece of adobe from the walls. Nothing. Just a small, white stone resting on the packed earth. I shrugged it off, blaming a pocket gopher or some other burrowing creature.
A few minutes later, another thud, this one closer. I spun around, catching a glimpse of a stone, the size of a golf ball, appearing out of thin air and landing with a puff of dust. It was as if the air itself had condensed into rock. A chill ran up my spine despite the heat. I scanned the empty graveyard, the broken walls, the mesquite trees beyond. There was no one. No movement. Only the stones.
Then it escalated. Stones began falling in a rhythm, some small, some large, pinging off the headstones and thudding into the dirt around me. They seemed to concentrate near the back of the church, where a shadowy alcove held a faded statue of the Virgin Mary. I edged closer, my heart pounding. The stones came faster, one striking my ankle, another grazing my shoulder. I heard footsteps behind me, a crunch of gravel, but when I whirled around, there was nothing.
I stumbled back to the car, my hands shaking, a small chalky stone clutched in my fist. I had taken one as a witness. It was white, smooth, and cool, almost unnaturally so. I drove away, leaving the mission behind, but the feeling of being watched lingered for the entire drive home.
That night, I examined the stone. It seemed ordinary, but as I held it, I felt a faint vibration, as if it were alive. The color began to fade, leaching out of it until it was a dull gray. I’ve kept it in a drawer ever since, but sometimes, in the dead of night, I hear a faint thud against the wall, a sound like a stone hitting adobe, and I know the mission hasn’t forgotten me. I haven’t decided if I’ll go back. The stones may have stopped throwing themselves, but the question of who—or what—threw them remains, a haunting that follows me like a shadow.
