Chapter 4 - The Ledger of WarThe elevator chimed softly as it reached the fortieth floor, the doors sliding open to reveal a scene of absolute devastation.

The executive accounting floor—usually a pristine labyrinth of glass partitions, quiet clicking keyboards, and soft beige carpeting—looked like a hurricane had blown through. Monitors were smashed, filing cabinets had been ripped open with crowbars, and loose paper snowed across the floor like confetti.
"They were thorough," Mason muttered, his pistol drawn and sweeping the corners of the open-plan office.
"They were sloppy," I corrected, stepping past him with surprising steadiness. I walked straight toward my old cubicle in the corner, ignoring the splintered wood of my desk. "Amateur thieves look for cash and jewelry. Professionals who destroy hardware leave the hard-copy secondary logs intact because they don't know how old-school accounting works."
Gabriel stepped up beside me, his eyes scanning the shadows of the hallway. "Explain."
"Digital footprints can be wiped remotely," I said, dropping to my knees despite the stabbing pain in my ribs. I reached beneath the destroyed wooden housing of my primary desk, feeling along the underside until my bandaged fingers clicked against a hidden magnetic latch. I pulled down a small, fireproof metal cassette box. "The IRS requires physical paper trails for subsidiary tax audits dating back three years. I never trusted the cloud."
I flipped the brass latches and opened the box. Inside lay neat stacks of ledger sheets, handwritten reconciliation notes, and a micro-SD card containing every encrypted wire transfer made through the Kane Corporation over the last twenty-four months.
"Jackpot," Mason breathed.
Before I could lift the micro-SD card, a red laser dot flickered across the white paper in my hands.
Clack.
The distinct sound of a round chambering echoed from the executive boardroom down the hall.
"Get down!" Gabriel roared, throwing his body over mine just as a hail of automatic gunfire chewed through the glass partition above us, raining razor-sharp shards of safety glass onto our backs.
"Sniper in the ventilation catwalk!" Mason yelled, returning fire with three rapid shots down the long corridor.
Gabriel hauled me up by my uninjured arm, shoving me behind the reinforced concrete pillar of the elevator bank. His face was inches from mine, his breathing controlled, his eyes locked onto mine with terrifying clarity.
"Are you hit?" he demanded.
"No, I'm fine!" I gasped, clutching the metal box to my chest like a shield. "The micro-SD card is in my hand. If they destroy this box, we lose the identity of the mole."
Gabriel’s jaw set into a hard line of absolute resolution. He reached down to his belt, unclipped a heavy tactical flash-bang grenade, and pulled the pin with his teeth.
"Stay behind the pillar, Claire," he whispered. "When I throw this, cover your ears, count to three, and run for the private stairwell at the end of the hall. Mason will be waiting there."
"And you?" I asked, my voice catching in my throat.
Gabriel didn't answer with words. He just gave me a look that promised he would tear the entire building down brick by brick before he let anyone touch me again.
He tossed the grenade around the corner.
Flash. Deafening roar.

As the shockwave echoed through the forty-thirteenth floor, Gabriel surged out from behind the pillar into the smoke, firing his weapon into the chaos.
I didn't hesitate. Clutching the metal box, I turned and sprinted toward the stairwell, diving headfirst into the concrete abyss as the real war for Chicago officially began.
