The Lung in the Wall

Daesung Jugong Complex Three was scheduled for demolition the following spring. That was why we'd bought in so far below market value. Everyone told us we were foolish — who puts money into a building that's already condemned — but my wife held fast to one simple fact: it would be the first home we'd ever truly owned. Let's live there, even briefly, she said. Let's have that time together before it's gone. I told her that opening up one of the living room walls would fix the cramped layout, and I picked up a hammer myself rather than call a contractor.

When we tore away the wallpaper, we found plywood instead of concrete. The building had gone up in the late seventies, and there were compromises throughout — but this wall, the one between the living room and the small bedroom, had apparently never been poured at all. When we pulled the plywood free, a hollow space opened behind it, just wide enough for a person to stand inside. It appeared on no blueprint we had ever seen. My wife laughed and said old buildings always had odd gaps like that, leftover spaces from the original plans, but I couldn't stop thinking about the warm air rising out of the dark. It was warmer than the room around us. And there was a smell — faint, but unmistakable. Wet earth.

I shone a flashlight in. At first I thought the insulation had swollen and buckled. But covering the entire inner surface of the cavity was a smooth membrane, pale pink, stretched across the walls like a second skin. It glistened. When the light hit it, a faint tracery of lines showed through from underneath, thin as capillaries. And the membrane was moving — slowly, with great patience — expanding and then subsiding, expanding and subsiding. Like the lung of something enormous, breathing quietly inside the wall. I nearly dropped the flashlight. Behind me, my wife went very still.

"It's mold," she said, as though she were telling herself. "Just a mass of mold." I wanted to believe that too. So I pulled on a glove and pressed one finger against the edge of the membrane. It was warm. A few degrees below the temperature of a human hand. And where I pressed, it flinched — a small, unmistakable contraction. Mold does not flinch. We propped the plywood back into place, sealing the gap, and spent the night on the living room sofa without sleeping.

The next morning I went to see the old man next door. He had lived in the complex for forty years. When I brought up the wall, his face went blank. He was quiet for a long time before he asked whether I knew what had stood on this land before the buildings went up. A marsh, he said. Black water that kept rising no matter how much fill they brought in, a place the old locals had always avoided. There were rumors that some of the construction workers had seen something strange when they dug the foundations. "Have you ever noticed the walls feel warm?" he said. "They all do, in every unit here. Even in winter, the inner walls are lukewarm. Everyone just assumed the insulation was good." He said nothing more, and closed his door.

That evening I began to listen to the apartment — really listen — and once I had started I could not stop. From behind the bathroom tiles. From behind the built-in wardrobe in the bedroom. From beneath the kitchen sink. The same slow, regular pulse, everywhere. When I pressed my palm flat against the wall I could feel it: the warmth, the faint tremor passing through the plaster. The membrane in the living room was not confined to that one hollow space. It had spread through the walls of the entire apartment — of the entire building, perhaps. We had been living inside something. For forty years, hundreds of families had slept and eaten and raised children within its body, and not one of them had known.

My wife said we had to leave. I agreed. But that night the plywood shifted and fell inward on its own. In a single day the membrane had grown. It now nearly filled the cavity, and its edges had begun to reach out across the living room floor, feeling their way forward like fingers. And its surface had changed. Raised forms had appeared on the membrane — the contours of human faces, pressing outward from within. No eyes, no mouths, but faces nonetheless. Many of them. As though those trapped inside were straining toward the surface, trying to come through.

I thought of what the old man had said. The black water that kept rising. The old stories about people who had gone in and never returned. Perhaps this thing had been absorbing them, slowly, over forty years. Growing inside the walls, feeding on the warmth of the boilers, drawing in the breath of sleeping people night after night. The lukewarm comfort we had been so glad of — that had been the body heat of something alive.

The following morning I went to the building management office and told them everything. The superintendent stared at me the way you stare at someone who has lost his mind, and then his expression shifted into something harder to read, and he asked in a low voice: "You're in Building 401? The family upstairs said something similar last year." He paused. "They didn't move out, though. Stayed on." He didn't finish the thought. I understood the silence that night. I found my wife standing motionless in front of the living room wall, her palm pressed flat against the membrane, smiling. "It's warm," she said. "Let's stay. We can't let them tear this down. They can't tear this down." Her voice sounded like something else speaking through her.

I grabbed her by the wrist and pulled her out of the apartment. Looking back from the corridor, I could see the pale pink edge of the membrane already pushing through the gap beneath our front door. We drove straight to her parents' house. It took three days for my wife to come back to herself, and when she did, she remembered none of it.

The following spring, Daesung Jugong Complex Three was demolished on schedule. I watched it on the news. When the charges detonated and the building folded into itself, something was briefly visible through the cloud of dust and debris — an enormous mass of pale pink, exposed for just a moment before the rubble swallowed it. The announcer called it insulation material from the aging structure. No one seemed to see the faces rising across its surface. A new apartment tower is going up on the site now, taller than what stood before. I read that the groundwater keeps flooding the excavation and pushing the schedule back.

Sometimes, even now, my wife reaches toward the wall in her sleep. The walls of our new apartment are cold. Every night I press my palm against them to make sure. Cold. Still cold. But last night, in her sleep, she murmured something. Warm, she said. Just that one word. I got up with the flashlight and stood there in the dark, and I began, very slowly, to examine the wallpaper.
