June sent her officers to secure Helen's home before any of us moved toward it. I stood in my driveway with the tablet still warm in my hands and watched them cross the lawn in pairs. Simone stayed close to Helen. Helen stayed close to me. We had spent the morning as neighbors who barely understood each other. Now we were walking toward her basement because her dead son might be alive inside my house and because the only map to that fact ran through a cable under our shared fence.
The firefighters came first. They checked Helen's doors and windows and the locks on them, and one of them said there was no remote lock controlling the rear door. That mattered more than it sounded like it should. My own house had already locked itself on command. I did not want to learn that Helen's house could do the same thing while we were standing inside it.
Naomi stayed outside with an officer. I saw her arms folded tight across her chest and her eyes fixed on the ground, and I thought about how much of this morning she had already carried. She had run across a lawn with a tablet showing strangers standing in my driveway. She had watched her grandmother's story turn inside out. She did not need to watch the next part from the basement steps.
Simone, Helen, and I entered through the rear door. The kitchen smelled faintly of coffee and tomatoes, ordinary. Helen did not pause there. She led us down the basement stairs, and the air changed with each step. It smelled of soil and machine oil, damp concrete and old metal, the smell of a place that had been worked in for decades and never quite aired out.
Shelves lined the walls. I saw old telephone equipment stacked in careful rows, handsets and junction pieces and coils of wire, and radio parts in boxes that had been labeled by hand. Metal boxes stood along one wall, each one marked with a year in Helen's neat block print. Nothing down there looked like decoration. Everything looked like it had once had a job, and Helen had kept it because she understood the job it had done.
Helen crossed to the far wall and moved a workbench away from it. The bench scraped against the concrete floor, and I helped her steady it when it caught on a crack. Behind it was a small access panel, set low in the wall, painted the same color as the concrete so that a person walking past would not notice it unless they already knew to look.
"I found this after Aaron died," Helen said.
Her voice did not shake. It sounded like a woman stating a fact she had carried for a long time and only now had a reason to say out loud.
She opened the panel. Inside was a row of communication cables. Some were modern, sheathed in smooth plastic, with connectors I recognized from my own router and modem. Others were older, thicker, with cloth wrapping and metal fittings that belonged to a different era of telephone work. They ran together in a bundle, and I could see where someone had tied them off with care, not haste, as if the person who did it expected the work to last.
Helen traced one blue cable with her finger. She followed it along the wall and down toward the floor, and then she looked at me.
"It connects to Marcus's house," she said.
"How?" I asked.
"Old cable television conduit," she said. "The two properties once shared a utility branch. BrightCurrent reused it without either of them knowing."
I thought about my own basement, about the electrical panel beside the garage and the false breaker cabinet I had never questioned, and I felt the floor shift under that thought. My house and Helen's house had been connected long before either of us knew it, and a company had found that connection and used it while we lived on opposite sides of a fence and traded tomatoes and packages and Sunday dinners.
Helen opened a metal junction box set into the wall beside the panel. Inside was a device no larger than a paperback book, its casing dull gray, with a small amber light blinking in a slow, steady rhythm. A label on the front read BURKE TEST NODE 01.
"My son installed this before Naomi was born," Helen said.
Simone leaned closer, careful not to touch anything yet. "What did it do?" she asked.
