The Silica Slipped

In the autumn of 2016, I was the sole technician at the Highland Croft Museum’s conservation lab, a converted stone barn tucked behind the main building. My job was to preserve artifacts from the surrounding peat bogs—tools, textiles, even the occasional bog body. The lab was cramped, lit by a single fluorescent strip that buzzed like a trapped wasp, and I often worked alone for days on end. The nearest person was the curator, Mrs. Fenwick, who visited twice a week to check progress and bring supplies.

One Tuesday, after a particularly heavy rain, I was cataloging a set of Iron Age leather shoes when I heard a small, sharp click from the corner of the room. It was the sound of a pebble striking the flagstone floor. I glanced down, expecting to see a loose screw or a button from my own coat. Nothing. The floor was bare, save for the dust I’d tracked in. I shrugged it off, attributing it to the old building settling. But when I stood to fetch a fresh pair of gloves from the drawer, I noticed something on the workbench: a small, pale yellow stone, perfectly smooth and spherical, about the size of a marble. It sat next to the shoe I’d been examining, as if placed there.

The stone was warm to the touch, unlike the cold glass of the cabinet or the metal tools. I picked it up, turned it over. It was flawless, almost artificial in its uniformity. There was no logical explanation for it. The windows were sealed shut, the door had been locked, and I’d been alone for hours. I didn’t feel frightened; just a deep, itching curiosity. I put the stone in a small plastic specimen jar and labeled it ‘Unknown, Found 2016-10-18.’ I planned to show it to Mrs. Fenwick.

That evening, I went home to my cottage on the edge of the moor. I slept restlessly, dreaming of the bog—of dark water and tangled roots, and a distant hum like a lowland pipe. The next morning, I found a similar stone on my kitchen table, though I was certain I had not brought it from the lab. It was identical in color and shape. I laughed nervously, blaming a prank from the village kids, but the stone sat there, heavy and deliberate.

Over the next week, the stones began to appear wherever I focused my attention. I’d be reading a report, and find one beside the page. I’d be scrubbing a pot, and a pebble would tumble from the water. They came in twos and threes, always the same pale yellow, always warm. I started to feel watched, not in a malicious way, but with a patient, ancient curiosity. My dreams grew more vivid: I was standing in a circle of standing stones, and the ground beneath me was made of these pebbles, shifting and whispering.

I told Mrs. Fenwick about the first stone, but she dismissed it as a mineral trace from the bog, maybe a concretion. She didn’t see the ones I’d collected in a jar on my desk—there were now a dozen. I showed her, and her face paled. She recognized them. ‘They’re made of chalcedony,’ she said, ‘but that’s not what worries me. These are the kind of stones they used to find in the graves of the bog people. The ancient ones believed they calmed the restless dead.’ She told me that the museum had a relic from a dig—a small leather pouch, still sealed, that rattled when shaken. It had been found in a bog body’s grip. When she opened the pouch for me, inside was a handful of yellow pebbles, identical to mine.

That night, I couldn’t sleep. The stones had multiplied overnight. My jar was overflowing onto the bench. I decided to return them all to the bog. I drove to the site where the body had been found, a desolate stretch of peat. I walked to the center, where the water seeped through my boots, and I poured the stones from my pockets into a dark pool. As they sank, the water rippled outward. For a moment, there was a deep, resonant hum, like the drone of a bodhran, and then silence. I felt a shift in the air, as if something had released its hold.

I drove home, exhausted but relieved. The next morning, I woke to find a single yellow stone on my pillow, still warm. Underneath it was a note, written in a spidery hand on linen paper: ‘We gave you back your dead. Now you must keep our promise.’ I haven’t told anyone else. The bog is quiet, but I know it’s waiting. And every night, I check my pillow, dreading what I might find.
