It was a scorching summer afternoon in Dallas, Texas. Traffic crawled down the avenue, horns blared endlessly, and waves of heat rose from the pavement like phantom waves.

Four days later, Dallas was buzzing with excitement for the Vance Foundation Gala.

Using cash David had hidden in the cabin’s floorboards, we bought plain, unpretentious clothes at a local Walmart in Marshall, along with dye to color David’s dark hair black and a razor to clean up his facial hair. With his beard neatly trimmed, a dark suit from a secondhand shop, and a pair of non-prescription glasses, David transformed once again. He didn't look like a homeless man anymore; he looked like a sharp, intense college professor.

At 2:00 PM on the day of the Gala, we arrived in downtown Dallas via a long-distance bus. The city was bathed in bright afternoon light.

We walked toward the First National Bank building—a massive forty-story tower of glass and steel.

"Remember," I whispered as we approached the revolving doors, "we have fifteen minutes max. Once your thumbprint hits that scanner, if my father has a flag on your name, security will be alerted."

David nodded, his jaw set firm. "I'm ready."

We walked into the cool, marble-lined lobby of the bank. David walked straight to the vault counter in the basement level, while I stayed in the main lobby, keeping watch near the entrance.

David handed his physical key to the elderly vault clerk. "Safety deposit box 408, please."

The clerk typed the number into her terminal. "Name, sir?"

"David Parker."

The clerk nodded. "Please place your right thumb on the biometric scanner."

David placed his thumb on the glowing glass surface. A green light flashed: IDENTITY CONFIRMED.

"Right this way, Mr. Parker," the clerk said, turning to fetch the master key.

Meanwhile, in the main lobby, my heart stopped.

Two black SUVs pulled up sharply onto the curb outside the bank’s glass doors. Four men in suits stepped out, led by Marcus Vance. They were scanning the street, holding earpieces to their ears.

They flagged the system, I thought in terror. The moment his thumbprint hit the scanner, Marcus got the location!

I ducked behind a marble pillar and pulled out a prepaid burn phone I had bought at the bus station. I dialed the number of the vault clerk's desk phone, which I had memorized from the bank’s online directory.

The phone at the desk rang. The clerk picked it up. "Vault department."

"Tell David Parker to move NOW!" I shouted into the receiver. "They are in the building!"

Down in the vault, David heard the commotion. He didn't wait for the clerk. He grabbed the heavy metallic box labeled 408 out of its sleeve, slammed it onto the table, and unlocked it with his key.

Inside was a thick, waterproof binder packed with original blue-stamped survey maps, signed chemical disposal manifests bearing Richard Vance’s personal signature, and a USB drive containing recorded phone conversations between my uncle Charles and the disposal company.

David shoved the binder and the USB drive into his leather messenger bag, grabbed the bag, and ran toward the vault door just as Marcus’s men hit the basement stairs.

"Parker!" a guard screamed.

David pulled a fire alarm lever on the wall.

A deafening siren echoed through the subterranean corridors, triggering overhead sprinklers and dropping emergency fire doors. Water showered down in cold, blinding sheets. Panic erupted in the bank as alarm lights flashed red.

In the chaos of screaming bank employees and rushing patrons, David slipped through a service door that led into the underground utility tunnels connecting the financial district buildings.

I ran out the side exit of the bank, meeting David at the end of the alleyway as planned.

He was soaked, breathing heavily, but he was clutching the leather messenger bag tightly against his chest.

"Did you get it?" I gasped.

David unzipped the bag, revealing the blue-stamped documents. "Every single piece. It's all here, Madison. Enough to put your father, your uncle, and their entire board of directors in prison for the rest of their natural lives."
