Chapter 10 - The Broken Cipher
Julian stood motionless in the freezing wind, the chemical slush soaking through his boots. He reached slowly into his jacket, his fingers brushing against the empty space where the silver pouch had been. He didn't have it. In the chaos of the boiler room, the pouch had been kicked aside into the shadows. But Arthur didn't know that.
""You don't need the pouch, Father,"" Julian shouted over the screaming jet engines, stepping forward with deliberate, steady strides. ""The silver drive was only a transceiver. The master algorithm isn't stored in hardware. It was coded using the double-entry balancing methods you taught me when I was twelve. The ones you made me memorize before you vanished.""
Arthur’s hand hesitated over the red button of the detonator. His cold blue eyes narrowed, searching Julian’s face for any tell, any micro-expression of deception. ""You're lying. You never had the capacity for high-level systems architecture. You were a glorified bookkeeper.""
""Ask Lucas,"" Julian said, his voice dropping into a dangerous, icy calm that surprised even himself. He took another step toward the airstair, closing the distance to thirty yards. ""Ask him what the last thing you whispered to him was before you sent him onto that offshore platform in the North Sea. You told him the ledger only balances when the debit matches the debt. That’s not corporate jargon. It’s an asymmetric encryption key derived from our mother’s maiden name and her death certificate number.""

Up on the gurney, Lucas stirred. His eyelids fluttered open, heavy with sedatives, his gaze drifting across the wet tarmac until it locked onto Julian. A faint, cracked whisper escaped his dry lips, inaudible over the jet engines, but his fingers twitched in a rhythmic sequence against the metal railing—three taps, a pause, then two taps. It was the childhood tapping game they used to play through the bedroom wall when their father came home drunk.
Arthur glanced down at Lucas, a flicker of genuine doubt and greed clouding his calculated expression. That single second of distraction was all Miller needed. The operative snapped his suppressed pistol up, firing two center-mass rounds into the guard standing immediately to Arthur’s right. The guard collapsed backward into the plane’s doorway, and the deafening crack of gunfire erupted across the open tarmac as the remaining security team opened fire.
