Chapter 4 - The Fire in the Floorboards

A dense, acrid column of chemical smoke erupted from the rear of the garage, drifting across the driveway in foul, yellow-gray clouds that smelled of melting plastic, sulfur, and burning circuit boards.
"Get inside!" Arthur shouted, grabbing my arm and pulling me back into his hallway as the deputies across the street began shouting tactical commands into their radios.
The two cruisers at the curb revved their engines, backing up thirty feet to create a barrier, while three more patrol units and a county fire rescue truck screamed down Whispering Pines Drive, their sirens waking every neighbor within four blocks. Porch lights began flickering on down the street like a constellation of panicked, bewildered eyes.
Deputy Callahan sprinted across the asphalt toward Arthur’s porch, her face covered in a fine layer of gray soot, coughing violently into her sleeve.
"Detective Vance!" she gasped, catching her breath against the storm door. "The entry team triggered an automated thermite charge. The moment Miller cut the secondary zip-tie on the internal door, an incendiary fuse ignited the server rack. It's a clean burn—military-grade thermal destruction. The hard drives are melting into slag right now."
"Is anyone inside?" Vance demanded, shoving his legal pad into his coat pocket.
"The space was empty when the fuse blew," Callahan said, wiping a black smear from her cheek. "There’s an egress tunnel, Detective. A fifty-foot galvanized drainage pipe, four feet in diameter, burrowed from the back corner of the crawl space under the property line, terminating inside the concrete culvert beneath the state highway."
I stood in Arthur’s entryway, clutching Lily against my chest so tightly she let out a small, sleepy whimper. My mind was spinning, fracturing under the weight of details that made no sense, that belonged in a geopolitical thriller, not in the life of a thirty-two-year-old high school biology teacher and her quiet architect husband.
"David built that culvert," I whispered, the memory hitting me like an open-handed blow. "Last August. He told the county water board that the rainwater runoff from the conservation ridge was eroding our back slope. He offered to pay for the drainage pipe out of our own pocket. He spent three weeks down there with a mini-excavator."
Detective Vance turned to Deputy Callahan. "Get the state police on the radio. Put out a BOLO for David Miller. What does he drive?"
"A gray Ford F-150," I said, my voice shaking so hard I could barely form the syllables. "License plate... Wisconsin plates, Delta-Echo-seven-nine-zero-two."
"He didn't take the truck to Chicago?" Vance asked, his eyes narrowing.
"He said he took an airport shuttle from the long-term lot at Mitchell International in Milwaukee," I replied. "He told me he didn't want to leave his truck parked on the street in downtown Chicago."
Vance pulled out his personal phone, dialed a direct extension, and held the receiver to his ear.
"Sarah, run a priority interstate query," Vance said into the phone, his voice clipping every word with urgent authority. "David Andrew Miller, date of birth October fourteenth, nineteen-eighty-nine. Check all parking access logs for Mitchell International, O'Hare, and the regional bus lines for the last twenty-four hours. And pull the FAA flight manifests for every commercial departure from Milwaukee to Chicago from yesterday morning."
He waited thirty seconds. The sirens from the fire trucks outside were deafening now, drowning out the hiss of the rain against the roof. Firefighters in yellow turnout gear were hauling heavy four-inch hose lines down my driveway, their boots splashing through the puddles as they prepared to flood the smoking crawl space beneath my living room.
Vance listened to the voice on the other end of the line.
Slowly, his jaw tightened. His eyes flickered to my face, holding a look of profound, devastating pity.
"Nothing?" Vance asked into the receiver. "Check under his legal aliases. Check his social security number."
He paused, listening again.
"Understood. Flag the passport. Put a national NCIC red notice on his name and vehicle registration."
Vance hung up. He looked at me through the dim light of Arthur’s foyer.
"Mrs. Miller," he said, taking a slow, steady breath. "There is no record of your husband booking a flight out of Milwaukee yesterday. There is no record of him checking into the Marriott in Chicago. And according to the state department’s commercial registry, the Midwestern Architectural Summit in Illinois ended four years ago when the sponsoring foundation dissolved."
The world seemed to drop away beneath my feet.

"Then where is he?" I whispered.
"I don't know where he is right now, Emily," Vance said, stepping closer, his voice dropping to a gentle, lethal murmur. "But three hours ago, his cell phone signal didn't ping off a cell tower in Chicago. It pinged off the cellular repeater tower on the water tank half a mile behind your house."
