Read Chapter 15: The Casino's Heart

The fuel depot smelled of diesel and damp concrete, and race morning did nothing to improve it. Through the grimy windows, the first light of dawn painted the harbor in pale gold, yachts bobbing like patient spectators waiting for the main event. Somewhere above the city, the first practice engines began to whine.

Jules knelt beside the transmission housing, his tablet balanced on a stack of oil-stained crates. The device in his hand was smaller than Alex had expected—a wafer of black circuit board wrapped in heat-resistant tape, no bigger than a matchbox.

"Integration point's clean," Jules said, not looking up. His fingers moved with the precision of a surgeon. "Primary trunk line feeds the settlement system from the cage through the casino's internal network. I tap in here, the data stream hits my relay first, and I spoof the confirmation codes at the bank level."

Zoe stood by the door, arms crossed, watching the street through a crack in the blinds. Her body was still coiled tight from the argument two nights ago. She hadn't mentioned the kill-switch again. Neither had Alex.

"How long before someone notices a latency spike?" Alex asked.

Jules grinned. "I built a compensating buffer. The system sees what it expects to see. The transfer logs will show normal traffic, normal timing. The only difference is the destination."

"Which is what, exactly?"

"An account that doesn't exist until tonight." Jules sealed the device into place with a bead of industrial adhesive and tested the connection. A small LED blinked green. "After that, it evaporates. The money lands, and then there's no account, no trail, no nothing."

Alex checked his watch. 07:42. The gates opened to spectators at nine. The settlement cycle ran at close of business, but the Grand Prix weekend threw the schedule off—continuous betting, rolling settlements, the cage processing cash and chips on a twenty-hour cycle. Their window was still tight.

He grabbed his blazer from the hook by the door. "Zoe's with me. Casino floor reconnaissance. Jules, you stay here and babysit the relay. I want a full diagnostic by noon."

Jules waved him off without looking up. "I could do this blindfolded."

"Which is exactly why I'm trusting you with it."

The casino was a different beast on race morning. The crowds hadn't arrived yet, but the building was already humming with activity—cleaners buffing marble floors, pit bosses running calibration checks on the tables, security doing their final sweep before the doors opened. Alex and Zoe walked in through the staff entrance, using the badges they'd lifted from two low-level floor managers three weeks ago. Their names matched the photographs. Their cover story matched the schedule—maintenance supervisors conducting a pre-event walkthrough.

Zoe moved beside him with the easy grace of someone who belonged in the building. She even walked different—shoulders back, stride measured, nothing of the guarded tension she'd worn at the depot. It was unsettling, how quickly she could become someone else. Alex had seen her do it a dozen times, and it still made the back of his neck prickle.

They crossed the main floor, weaving between tables being set with fresh cards and racks of chips. The vault guards were positioned where Alex remembered them from his years at the tables—but they'd changed the rotation since the firmware discovery.

"Two at the north entrance," he murmured, barely moving his lips. "One at the corridor junction. That's new."

Zoe glanced past him, cataloguing. "The corridor's been sealed off. Look at the tape line on the floor."

Alex followed her gaze. A fresh line of yellow caution tape ran across the maintenance corridor entrance—the one that led to the central cage's service access. Behind it, a camera had been mounted at a new angle, one that didn't match the casino's usual coverage map.

"That wasn't there Monday," he said.

"Laurent's doing." Zoe's voice was flat. "He's tightened the funnel. Anyone who goes for the cage has to pass through that corridor, and that corridor's now a kill box."

They drifted toward the bar area, where the espresso machine offered cover for loitering. Alex ordered two coffees he had no intention of drinking and used the time to study the floor layout more carefully.

The central cage sat at the heart of the casino, a glass-and-brass box that never closed. It processed the casino's lifeblood—chips for high rollers, cash for the desperate, settlement transactions for the betting windows. On a normal day, it held maybe eight million euros. On Grand Prix Sunday, with the high-stakes rooms running triple their usual action, that number would climb toward thirty.

Viktor had changed the digital vault codes, killing their original plan. But the physical cage still had to operate. The tellers still had to move cash from the vault to the cage and back. The maintenance pit beneath the floor still had to function, because you couldn't run a twenty-hour settlement cycle without service access.

"I count eight guards on the floor," Zoe said, sipping her coffee. "Two more on the mezzanine. That's thin for a race weekend."

"They're not worried about the floor." Alex watched a security supervisor speak into his headset, then glance directly at the corridor with the caution tape. "Laurent's pulled his people inward. He's protecting the cage and the vault, and everything else is a distraction."

"That's good for us."

"Or it's bait." Alex set down his cup. "He knows we're coming. He's made it impossible to get in through the network, so he's betting we'll go physical. The trap is set for exactly what we're planning."

Zoe was quiet for a moment, her eyes fixed on the corridor. "Then the ledger changes everything."

"Right. Jules takes the ledger first—from wherever Viktor's hiding it—and Laurent has to split his response. He can't keep his force concentrated on the cage if his own boss's private records are walking out the door."

"Assuming Jules can find it."

"He found the firmware. He found the routing system. He'll find the ledger." Alex said it with more confidence than he felt.

One of the vault guards shifted position, moving from the north entrance to the south. Alex clocked the timing—forty-seven seconds between posts, predictable as a metronome. He filed it away.

"There," Zoe said, barely audible.

Alex followed her gaze. A maintenance supervisor was wheeling a cart toward the corridor entrance, and the guard at the tape line barely glanced at his badge before waving him through. The cart was loaded with cleaning supplies—nothing remarkable—but Alex noted the supervisor's unhurried pace, the way he didn't stop to chat, the way he disappeared into the corridor's shadow without looking back.

"Logistics runner," Zoe said. "Extra supplies for a sealed-off area. They're stocking the kill box."

"They want us to think the corridor is closed. But they're making it functional."

"Because they think we're coming through it."

Alex let that settle. Laurent's counter-surveillance was thorough, but it was also predictable. He'd built a cage of his own, and cage-think had a flaw: it assumed the prey would come to the bars.

"We're not going through the corridor," Alex said.

Zoe turned to face him, her espresso cup held like a shield. "Then how do we get to the cage?"

"The maintenance pit runs under the entire floor. The crawlspace access points are marked on the original building plans, before Laurent's retrofits covered them." Alex kept his eyes on the vault doors. "Laurent sealed the obvious routes. He's forgotten the ones in the walls."

"You're sure?"

"I spent six years in this building. I know every pipe, every conduit, every service panel." He finally met her eyes. "Trust me on this one, Zoe."

She held his gaze for a long moment, something unreadable in her expression. Then she gave a single, tight nod.

Behind them, the casino's main doors opened for the first wave of spectators, and the day's noise flooded in—chips, conversation, the electric anticipation of money about to change hands. Alex felt the familiar pulse of the building waking up around him, millions of euros beginning to flow through the systems Jules was even now tapping into.

Thirty-one hours until the settlement window closed.

Thirty-one hours until everything either came together or came apart.

His phone buzzed in his pocket. A message from an unknown number, three words that made his blood run cold:

*He's coming tonight.*

Alex stared at the screen, then locked it and slid the phone away before Zoe could see. But his fingers were already tapping against his thigh, a nervous rhythm he couldn't stop.

Viktor. On-site. Tonight.

The plan had a new variable, and Alex had just become the crew's biggest liability.
