My wife heard it first. She came downstairs on our second Tuesday in the new house and told me there was scratching in the bedroom wall — not mice, she said, not the sound of small things, something else. I went up and pressed my ear to the drywall above the baseboard and I heard it: a slow, rhythmic scraping, like fingernails dragged across stone, but muffled, as if it were happening several feet inside the wall.
We called an exterminator. He walked the perimeter of the house and inspected the attic and the basement and told us there were no signs of infestation, no entry points, no droppings. He knocked on the walls. He used a scope. He found nothing. He charged us two hundred dollars and told us old houses make sounds.
The scratching continued. It moved. That's what I recorded in my notes — I kept notes from the third week onward, because I am a methodical person and I needed to be methodical about this — it moved through the walls in a pattern. Starting at the northeast corner of the bedroom, then the south wall of the hallway, then the kitchen, then back. The same route, or something close to the same route, every night between 11 PM and 2 AM.
My wife started sleeping in the guest room. I don't blame her.
I tore open the wall. I know this sounds impulsive but I want you to understand I did not do it impulsively: I waited three weeks, I consulted a contractor, I made sure the wall was not structural, and then I opened it with a reciprocating saw along the baseboard and pulled the drywall back.
Inside the wall was a layer of older material — plaster, the original wall, which would have been the exterior wall before the house was expanded in the 1960s, according to the records I pulled. In the plaster, at the height of my knee, someone had scratched something. I don't mean carved or etched. I mean scratched, the way you scratch with your fingernails when you are trapped somewhere and the scratching is not decorative, it is not a message, it is just the thing you do because you are there.
The scratches covered a three-foot section of the plaster. There was no pattern in them. There was no language. There were a great many of them.
Inside the original wall — in the space between the old plaster and the new drywall — we found two things. The first was a small glass bottle, sealed with wax, containing a roll of paper. The paper, when we unrolled it, was covered in a dense, cramped hand: the same phrase repeated, again and again, for what appeared to be hundreds of repetitions. I had a linguist look at a photograph. She said the language was an archaic dialect she could not immediately place. She said the only words she could confidently translate were "don't let it" and "out."
The second thing was a hole.
Not a mouse hole. Not a gap in the construction. A hole in the exterior foundation concrete, six inches in diameter, perfectly circular, as if it had been bored from outside. It had been packed with something — rags, old newspaper, what appeared to be horsehair plaster and horsehair — all of it jammed in tight, all of it dating from the original construction period of 1947 based on the newspaper dates.
The plugging was meticulous. Whoever had done it had wanted nothing to come through that hole. They had used everything they could find and they had packed it solid and then built a wall in front of it.
I repacked the hole. I resealed the wall. I kept the bottle.
The scratching stopped.
For three days it stopped and I thought: whatever it is needs that channel, and now the channel is resealed.
On the fourth night I heard it again. Closer. Not in the walls.
In the floor.
