Chapter 7 - The Bug Sweep

By midnight, Detective Vance and a private counter-surveillance specialist named Marcus Vance (no relation) were inside our home with thousands of dollars of military-grade detection equipment.
Marcus was a short, stocky man with a grey beard and a no-nonsense demeanor. He carried a heavy yellow case filled with spectrum analyzers, thermal imaging cameras, and non-linear junction detectors.
"A hardwired tap is the holy grail of surveillance," Marcus explained as he hooked a spectrum analyzer up to our wall sockets. "Batteries die. SIM cards run out of data. But if you tap directly into the house's electrical grid, you can run high-definition audio and video indefinitely without ever stepping foot near the property again."
"Who installed it?" I asked, sitting on the couch with a blanket wrapped around my shoulders. Lily was asleep upstairs at my brother Aaron's house—we had evacuated her hours ago.
"Arthur Mercer spent twenty years representing electrical utility subcontractors," Daniel said grimly, sitting next to me. "He knew how home power grids worked. He helped me renovate this basement two years ago."
Marcus walked slowly through the living room, holding a device that looked like a flat paddle attached to a digital screen. He pointed it at the ceiling light fixture, then at the air vents, then at the brick fireplace.
Beep... Beep... BEEEEEP.
Marcus stopped in front of the main air conditioning intake vent near the hallway.
He pulled a thermal camera out of his bag and aimed it at the plastic vent cover. On the screen, a tiny bright orange dot glowed against the blue background—a heat signature.
"Gotcha," Marcus muttered.
He pulled a screwdriver from his belt, unscrewed the vent cover, and reached deep inside the metal ductwork. When he pulled his hand back out, he was holding a small, black rectangular box no bigger than a pack of gum. Two thin wires ran from the box, tracing back into the wall wiring.
"Fiber-optic micro-audio microphone and an infrared thermal sensor," Marcus diagnosed, laying it on the coffee table. "It listens to every word spoken in this hallway and tracks movement down the corridor."
"How many more are there?" Detective Vance asked sharply.
Marcus spent the next three hours tearing through our house.
He found a second microphone embedded behind the wall outlet in our master bedroom. He found a third microphone tucked inside the frame of a decorative wall mirror in the dining room that Margaret had gifted us for our anniversary three years ago.
By 3:00 AM, the coffee table was covered in wire fragments, tiny circuit boards, and plastic housings.
Our home—the place where we had brought our baby daughter home from the hospital, the place where we had celebrated Christmases and birthnights—had been completely compromised. It was an elaborate cage constructed by people who claimed to love us.
Detective Vance looked at the pile of evidence on the table, her jaw set in a hard line.
"This changes everything," Vance said, standing up and pulling out her radio. "The original warrant was for wiretapping based on the bear and the outdoor camera. This proves long-term, pre-meditated home invasion and illegal wiretapping spanning back years."
"What happens to them now?" Daniel asked.
"Arthur Mercer lied under oath during his bail hearing when he claimed he had no further access to surveillance systems," Vance said. "He violated his bail conditions before he even walked out of the courtroom. I'm securing a bench warrant for his immediate re-arrest tonight."

"And Margaret?" I asked.
"Margaret was the primary user of the monitoring software," Vance said. "With this new evidence, the DA is upgrading the charges to Felony Stalking with Aggravated Intent, Burglary, and Interception of Communications. They aren't getting bail this time. They're going to prison."
