Naomi moved in with Helen three months before the roof confrontation. I knew very little about her at first. She was sixteen. She rarely came outside. When I did see her, she moved quickly between the house and the car, or she stood at the upstairs window for a moment before the curtain closed. Helen told people she was recovering from a frightening incident at her previous school, and I accepted that explanation without question. It sounded plausible. Teenagers have difficult times at school. Grandmothers take them in. That was the story, and I had no reason to doubt it. I did not know then that the story was a cover, or that Naomi had come to Helen's house for reasons that had nothing to do with school and everything to do with fear.
What I also did not know, and what Helen would later explain to me in pieces, was who Helen had been before she retired. She had worked for thirty-four years as a communications technician for a regional telephone company, repairing relay systems and identifying unauthorized signals. That was not a hobby. That was her profession. She had spent more than three decades listening to signals that should not have been there and tracing them back to their source. When she noticed something wrong with my roof, she was not guessing. She was doing what she had done for most of her working life.
Eight weeks before the confrontation, Helen noticed a small reflection beneath my solar array. It was a tiny thing, a glint of something that should not have been there, and most people would have missed it entirely. Helen did not miss it. She watched it. At night, she detected short wireless transmissions coming from my roof. The signal was not constant. It activated only when the solar array reached a certain output, which meant it was tied to the power the panels produced. Every afternoon between three and five, data moved through an encrypted cellular relay. Helen could not read the data itself, but she could see the pattern, and the pattern told her enough. Something on my roof was transmitting, on a schedule, to somewhere else, and it was doing it using the power my panels generated.
Helen reported it to BrightCurrent Solar, the company that had installed my system. A technician arrived within twenty minutes. I remember hearing about this later and thinking how fast that was, how unusual it was for a company to send someone that quickly for a complaint from a neighbor about a system she did not own. By the time the police inspected the roof, nothing suspicious remained. The transmissions had stopped, or the device had been hidden, or whatever Helen had detected had gone quiet. The following day, the transmissions returned.
I think about that sequence now and I understand what Helen must have felt. She had found something. She had reported it. Someone had come quickly, too quickly, and then the evidence had vanished, and then the signal had come back as if nothing had happened. That is a lonely feeling, to know something is wrong and to watch the people who are supposed to help make it disappear instead.
Helen tried to warn me directly, and every attempt failed in a way that now feels almost designed. She placed two handwritten warnings in my mailbox. I never received them. I do not know whether someone removed them or whether they were lost, but they never reached me. She emailed me three times. Those messages went directly into my spam folder, and I never saw them. I checked my spam folder rarely, and when I did, I deleted things without reading them carefully. Her warnings were in there, waiting, and I threw them away without knowing what they were. She knocked on my door while I was away, and my BrightCurrent technician, who was inside updating the inverter software, told her I did not want to speak with her. I never gave that technician permission to say that. I never told anyone I did not want to speak with Helen. But Helen heard it from a man in a company uniform standing inside my house, and she believed him, or at least she had no reason not to, and so she stopped trying to reach me that way.
