Chapter 20
Marlene's retaining wall had been leaning all morning, slow and quiet, the way a tired man leans on a fence. Now it bowed. The whole six-foot run of stone bellied outward toward her yard, and as the base shifted, the dirt at the footing washed away in the black water, and something underneath it came into view that stopped all of us where we stood.
It was a timber header, sunk into the bedrock at the base of the wall, dark with age and wet, set vertically like a post that had been driven into the earth a hundred years ago and forgotten. I knew what it was before Bennett said it, because I had seen timber like that in old photographs of the coal country, but Bennett said it anyway, quiet, like a man naming something in a church.
"That's mine timber," he said. "That's an access timber from a drift."
Vasquez moved closer with her flashlight, carefully, the way you approach something that might still be dangerous, and the light found what was bolted to the timber. A brass inspection valve collar, green with age but still legible, stamped in deep block letters around its rim. Vasquez read it out loud, slow, because she wanted it on the record and because none of us quite believed it the first time through.
"State Environmental Protection," she read. "Borehole 9-C Injection Manifold. Unseal prohibited by order of State Court, 1977."
The rain was still coming down, but for a second nobody moved at all. Bennett crouched down with his phone and photographed the collar from three angles, wiping the lens on his sleeve between shots, while Vasquez read the stamp a second time, word for word, into her radio so dispatch would have it on tape. I watched her do it and thought about how strange it was that a piece of brass the size of a dinner plate, bolted to a timber under a garden wall, was the most honest document on this whole street. Everything else, the deeds and the title insurance and the tax records, had been arranged to lie. This collar had just sat there in the dark for decades, telling the truth to nobody.
Marlene knelt down beside the timber, not caring about the mud on her knees, and put her hand flat against the old wood. "This was here the whole time," she said. "When I planted the roses. When I mortared the wall. This was right under my hands."
"It was," I said. "The drift runs under both our lots. The coal company dug it a century ago to haul coal out of the ridge, and when the mine closed, the county found a use for it. A ready-made hole, already dug, already timbered. They didn't have to dig a cistern. They just had to open the valve."
Bennett asked what the valve was for, exactly, and I told him what I had pieced together over the years. The manifold valve was how they fed the waste in. The injection wells pumped it down, and the manifold spread it into the tunnels, and the collar was the county's way of saying this door stays shut. Unseal prohibited. Not because opening it would fix anything, but because opening it would let the whole works come back up at once, under pressure, with nowhere to go but out. Marlene asked if opening it a little would relieve the pressure, the way you bleed a radiator, and I told her no. A radiator has a system around it. This had a neighborhood around it. Bleeding it here would just pick a new place for the poison to come out, probably through somebody's basement floor.
Vasquez looked from the collar to the fence line, and then along the fence to where my trench ran, and I saw the moment the pieces joined up in her head. Her eyes tracked the white PVC posts, one after another, straight as a ruler, and then she looked down at the timber header, and then back at the fence again.
"Ray," she said slowly, "this fence. It runs right along the centerline of this header, doesn't it?"
I nodded, because there was no point in denying it anymore. "It does."
"So the fence wasn't built on the property line," she said. "It was built on top of the seam. To hide it."
"To hide it," I agreed. "A white fence, nice and straight, and nobody ever asks what's underneath a fence."
