Chapter 3 - The Audit Trail
The strategy was dangerous because it required absolute perfection. If Clara made a single error in her forensic tracing of the Munich telecommunications hardware, the federal authorities wouldn't just arrest Thomas Vance—they would freeze the accounts of Callahan & Price Logistics under the suspicion that the brothers were playing a double game.
For three days, the pavilion became an isolation chamber. Roman remained on site, his expensive suits replaced by dark, functional clothing as he took over the security details, his presence a silent, heavy weight that kept the local drivers and warehouse workers quiet. No one asked why the owner’s brother was patrolling the perimeter with a high-grade security scanner; in Blue Island, people knew better than to question a Callahan’s business arrangements.
Clara discovered the leak on Thursday afternoon. The digital signature hadn't been stolen from an old database; it was being generated live from a terminal located inside the Cook County Administration Building in downtown Chicago.
"Someone within the corporate records division is running a mirror server," Clara explained to Caleb and Roman as they gathered around her desk. She pointed to a series of encrypted IP addresses that were routing through a commercial VPN based in Panama. "Every time I file a new shipping manifest or an asset registration for our company, this server copies the validation tokens and applies them to Vance’s maritime bonds in Montreal and Detroit. To the federal customs computers, it looks like we are personally authorizing every shipment."
"Who controls the terminal?" Roman asked, his gray eyes narrowing as he leaned over the monitor.
"A senior clerk named Marcus Thorne," Clara said, clicking through to an employee profile she had pulled from the public county registry. "He’s been with the department for twelve years. His salary is sixty-two thousand dollars a year, but his private banking records—which I pulled through our old liquidation trust’s clearinghouse—show a series of cash deposits made at an automated teller machine in Rosemont every Friday afternoon. Exactly ten thousand dollars a week for the last three months."
"Thorne is an old associate of Silvano’s father," Caleb murmured, his fingers tapping a rhythmic, nervous beat against his thigh. "He used to handle the title transfers for the family’s real estate holdings in Cicero back in the nineties. He’s old guard, Roman. He thinks he’s loyal to the old name."
"He’s loyal to the ten thousand a week," Roman corrected coldly. He straightened his spine, his hands dropping into his pockets. "Silvano can have him in the back of the car by midnight. We can find out where Vance is staying before the market opens tomorrow morning."
"No," Clara said firmly, standing up from her chair and placing herself between the two brothers. "No cars, no midnights, no threats. If Marcus Thorne disappears, Vance will know his mirror server is compromised, and he’ll pull the plug on the Detroit shipments before the federal authorities can seize the cargo. We need that cargo to land at the rail yard so the evidence is undeniable."
Caleb looked at his brother, then back at Clara. The old instinct to strike first, to eliminate the threat with absolute, overwhelming force, was visible in the tension of his jaw. But as he looked at Clara—at the clipboard she still held like a weapon, at the intelligence that had saved them in Boston and Chicago—his shoulders slowly dropped.

"What do you need me to do?" Caleb asked.
"I need you to drive me into the city," Clara said, her voice steady and clear. "We're going to visit Marcus Thorne during his lunch break. And I'm going to show him exactly what an audit looks like when your life is on the line."
