Chapter 6 - Mark's Confession

The drive from our suburban development to Mercy General took twenty-five minutes in normal traffic. I made it in fourteen, the front tires of my station wagon screaming through the slush on the off-ramps, the speedometer needle hovering at eighty-five on the dark, empty stretches of the interstate.
The message hadn't come from Gary. It had come from Mark’s backup burner phone—the one he kept in his glove compartment for his construction side-jobs.
When I burst through the double doors of the fourth-floor waiting room, Mark was sitting on a low vinyl sofa beneath an artificial ficus tree. He still had the hospital visitor badge taped to the lapel of his fleece jacket, curled at the corners. He was holding a styrofoam cup of black coffee between his knees, staring down into the dark liquid as if he were waiting for it to tell him what to do next.
He didn't hear me approach. He didn't look up until my hand clamped down on the collar of his jacket, twisting the fabric until the zipper dug into his windpipe.
"Where is he?" I whispered.
The coffee cup dropped from his grip, splashing brown across the gray hospital linoleum and soaking through the hem of my borrowed yellow scrub pants. He didn't try to pull my hand away. He just stared up at me with hollow, red-rimmed eyes that looked as if they hadn't seen sleep in a month.
"He's not here, Elena," Mark rasped, his voice raw. "He didn't come to the hospital. He’s at the farmhouse in Clarksville."
"You sent that picture," I said, shoving him back against the vinyl cushions. "You stood outside our daughter's room and took a picture of her dying and sent it to me like a threat."
"Not like a threat," Mark choked out, tears finally breaking over his lower lids and cutting tracks through the gray stubble on his cheeks. "Like a warning. He took my phone, Elena. He mirrored the SIM card while we were at the station. He's tracking your vehicle. He knows you went back to the house."
I froze, my hand still twisted in his jacket. "What?"
"The truck," Mark said, his voice dropping to a frantic, dry rasp. "The GPS unit in the dashboard. It’s tied to his old fleet management account from the depot. He bought the car for us, remember? Three years ago as a 'wedding anniversary gift.' It wasn't a gift. It has a cellular uplink under the center console."
I let go of his collar. He slumped forward, his face in his hands, his breath coming in jagged, wheezing sobs.
"He was broke, Elena," Mark whispered into his palms. "The Clarksville warehouse didn't close because of OSHA violations. It closed because Dad was running an illegal chemical reprocessing operation behind the grain elevators. He took money from three different waste brokers in New Jersey to 'neutralize' surplus pesticides that were too hazardous for regional landfills. He took forty million dollars over seven years and buried the drums in the limestone quarries behind the river."
The air in the waiting room felt thin, suffocating. "And the insurance policy?"
"The EPA started soil core sampling in March," Mark said, lifting his head. "They found the leak. If the remediation team links the barrels back to the Vance Trust, Dad goes to federal prison for the rest of his life. Every asset he owns—the land, the accounts, the house, this house—gets seized under the Superfund forfeiture laws. Unless..."
"Unless there was an independent capital infusion," I said, the horror settling into my stomach like wet cement. "An accidental death settlement from a commercial policy that predated the federal investigation."
"Four million dollars," Mark sobbed. "Tax-free. Irrevocable. It was enough to settle the state fines and pay off the remediation contractor before the Department of Justice filed formal charges."
"And you knew?" I stepped back, looking at the man I had lived with for seven years, the man who had held my hand in the delivery room while I pushed Lily into the world. "You knew he was putting something into the bedroom wall?"
"No!" Mark shouted, his voice cracking loud enough that the receptionist behind the Plexiglas screen looked up with her hand hovering over the security buzzer. "I swear to God, Elena, no! He told me it was a ventilation test! He told me he was using an inert tracer gas to map the air leaks because he was going to install a secondary insulation barrier! He told me the silver packets were just soil neutralizers!"
"He had an inventory card in your handwriting, Mark!"
"He made me copy it from a logistics sheet!" Mark pulled at his hair, his fingers digging into his scalp until his nails were white. "He said if the inspectors came to the house, we had to show that any chemicals on the property were registered to an old agricultural research permit from 1984! I didn't know what Compound 1080 was! I didn't look it up! I was terrified, Elena! He told me if I went to the police, he’d produce the signature pages showing that I was a fifty-percent managing partner in the Clarksville LLC!"
"Are you?"
Mark looked away.
That was his answer. He didn't have to speak. The silence between us stretched out, thick with ten years of his weakness, his cowardice, his desperate need to keep his father’s approval even as the old man slowly ground our lives into ash.
"Where is the master ledger?" I asked, my voice dropping back into that flat, lethal register.
"You found it," Mark said, his eyes darting to my coat pocket where the corner of the leather notebook projected through the fabric. "That’s the only copy."
"No, it isn't," I said. "Because the ledger in my pocket stops at 'Contingency plan alpha.' What is contingency plan alpha, Mark?"
Mark’s face drained of what little color it had left. His lips trembled, but no sound came out.
"Mark," I whispered, leaning down until my mouth was inches from his ear. "Look at your daughter through that glass. She is nine years old. If you don't tell me what that old bastard is planning to do, I will walk into that police station, hand Detective Lin your name on every document from that basement, and watch them lock you in a cell until Lily is an old woman."
Mark looked at the window. He looked at the rhythmic rise and fall of Lily’s small chest beneath the hospital sheet.
"The air return," Mark whispered, his voice shaking so violently his teeth clicked together. "He didn't just plumb it into our bedroom, Elena. He installed a bypass valve into the main furnace supply line above the blower."
I stared at him, cold dread creeping up my neck. "What does that mean?"

"It means if the temperature in the house drops below forty degrees, the secondary heater kicks on," Mark said. "And the valve opens automatically. It flushes the entire six-gallon reservoir directly into the ductwork. If the fire department goes back in there with space heaters to keep the pipes from freezing... the whole block will be covered in a gas plume."
