The Homicide Squad bullpen at four-thirty in the morning smelled like ozone, stale sweat, and burnt filter coffee. The cleaning crew had come and gone, leaving the floors smelling faintly of industrial lemon, but it couldn't mask the underlying scent of a room where people regularly worked thirty-hour shifts.

Trent sat at his desk, staring at a dual-monitor setup that was burning a hole in his retinas. Beside him, Mac was cross-referencing a printed list of Marrickville business registrations with a highlighter.

"Three hundred and twelve registered fitness businesses in the Inner West," Mac said, her voice raspy. She tossed the highlighter onto the desk. "Cross-fit boxes, yoga studios, twenty-four-hour commercial chains. If they're running out of a gym, it's not a Fitness First. It'll be a private lease. A warehouse."

"Focus on the industrial zoning," Trent said, rubbing his eyes. "Sydenham borders. Marrickville South. Places with roller doors and no foot traffic after five."

A young man walked into the bullpen, carrying a thick cardboard file box and a tablet. He was wearing a faded Ramones t-shirt, jeans, and a pair of scuffed Vans. He looked like he'd just walked out of a university lecture, but the security lanyard hanging from his neck identified him as Joey Farah, Senior Intelligence Analyst for State Crime Command. Joey was twenty-six, Lebanese-Australian, and possessed a terrifying ability to find patterns in digital chaos. He didn't carry a badge, but he closed as many cases as any detective on the floor.

"Morning, vampires," Joey said, dropping the box on Trent's desk with a heavy thud.

"Tell me you've got something," Trent said.

"I've got a headache and a caffeine addiction," Joey replied, pulling up a chair. He woke up his tablet and tapped the screen. "But I've also got the telco returns on Liam Connor's phone, and the initial CCTV dump from the Homebush industrial park."

Mac sat up straighter. "Start with the CCTV."

"Constable Sharma out at Auburn LAC ran the footage from the surrounding streets near the mangrove dump site from six months ago," Joey said. He pushed the tablet toward them. "You asked for a V8. Between midnight and four a.m. on the night the victim went missing, we've got three vehicles fitting the audio profile. Two are standard Commodores, registered to locals. The third is this."

He tapped play on a grainy, black-and-white video. A vehicle rolled past a security camera mounted on a warehouse. It was moving slow.

"Ford FPV Pursuit ute," Joey said. "Dark colour. Probably black or midnight blue. Hard tonneau cover. Custom rims."

"Get a plate?" Trent asked.

"Camera's too high, angle's garbage," Joey said. "But look at the tray. It's riding low. Heavy suspension, or it's carrying weight."

"Like three blokes in tactical gear," Mac murmured.

"Exactly," Joey said. "I ran the vehicle make through the RMS database for the Marrickville area. There are forty-two registered black or dark blue FPV utes in the Inner West. I'm cross-referencing the registered owners against known associates of right-wing extremist groups. It's running now."

Trent nodded. "Good. What about Connor's phone?"

Joey sighed, leaning back in his chair. "That's where it gets ugly. Connor was clean. No drugs, no gambling debts. But he was active on a hookup app called Recon. It's a location-based app, heavily geared toward the fetish and kink community."

"I know it," Trent said.

Mac shot him a brief look but didn't comment.

"Right," Joey continued, unbothered. "Connor's profile was standard. But I pulled the server logs from the app developers. Two weeks ago, he started messaging a blank profile. No face, just a torso shot in a dark room. Handle was 'Sweeper_88'."

Trent felt the pieces locking together. The number 88 was white supremacist shorthand for Heil Hitler. The eighth letter of the alphabet.

"Aryan brotherhood," Trent said.

"Fits the profile," Joey agreed. "Sweeper_88 was aggressive. Used a lot of tactical jargon. 'Securing the perimeter', 'clearing the area'. He wasn't chatting Connor up. He was interrogating him. Finding out his habits. When he went to the park. Where he hung out."

"He was hunting," Mac said softly.

"Worse," Joey said. He swiped to the next screen on the tablet. "Sweeper_88 didn't just message Connor. He messaged the other two victims."

The bullpen went completely silent. Trent stared at the screen. The connection was concrete. Three dead men. One digital predator.

"The kid found in the National Park," Joey said, reading off the screen. "And Hong, the immigrant in Homebush. Sweeper_88 interacted with all three of them in the weeks before they died. He uses the app to find targets. He looks for guys who are isolated, or into edge-play. Guys who might be willing to meet in a dark park at two in the morning, expecting a scene, and getting an execution instead."

"Can you trace the IP?" Trent asked.

"Burner phones," Joey said, shaking his head. "Pre-paid SIMs bought with cash. They bounce off cell towers all over the city. He turns the phone on, sends a message, turns it off. But..."

Joey smiled. It was a sharp, predatory smile.

"But what?" Mac prompted.

"People are lazy," Joey said. "Sweeper_88 slipped up once. Four days ago, he forgot to turn off his Wi-Fi when he booted the burner phone. It connected to an unsecured public network for exactly twelve seconds before he killed it. Long enough for the app to log the IP address."

Trent leaned forward. "Where?"

"A commercial router registered to a warehouse on Victoria Road, Marrickville," Joey said. "Business is registered as 'Apex Iron'. It's a private gym. Invitation only."

Trent looked at Mac. She was already reaching for her jacket.

"Get me the leaseholder's name," Trent said to Joey.

Joey tapped his tablet. "Registered to a Brett Holden. Thirty-two. Two priors for assault occasioning actual bodily harm. Known associate of the Southern Vanguard, a white nationalist splinter group."

"That's our guy," Mac said.

"Holden owns a dark blue 2010 FPV Pursuit ute," Joey added, reading the final line of data. "Registration matches the partials we couldn't rule out from Homebush."

Trent stood up. He grabbed his Glock from the lockbox under his desk and shoved it into his shoulder holster. "Joey, send everything to the strike force server. Build the brief. I want warrants for the gym, Holden's residence, and the vehicle. Everything."

"You want me to wake up the magistrate?" Mac asked, checking her watch. It was 5:15 AM.

"Wake him up," Trent said. "Tell him we've got a serial operating out of a neo-Nazi clubhouse, and they're planning another hit tomorrow night. He'll sign."

"Where are you going?" Mac asked, seeing Trent heading for the door.

"Marrickville," Trent said. "I want eyes on that warehouse before the sun comes up."

---

Victoria Road in Marrickville was a long, ugly stretch of light industrial zoning. Panel beaters, wholesale butchers, and sheet metal fabricators sat behind high wire fences topped with barbed wire. It was a street built for utility, not aesthetics.

Trent parked the unmarked Commodore two streets over and walked the rest of the way. The sky was turning a bruised, dirty grey in the east. The morning traffic was just starting to build on the main arterial roads, but the industrial estate was dead quiet.

He found Apex Iron halfway down a narrow access alley. It was a cinderblock warehouse painted matte black. No signage. The windows were frosted over and covered with heavy steel grilles. A high corrugated iron fence surrounded a small concrete yard at the back.

Trent walked past the front, keeping his pace steady, looking like a local tradie heading to an early shift. He noted the security cameras. Two domed cameras under the eaves, covering the street. One pointing down the alley. They were high-end. Professional.

He turned the corner and moved down the side street, looking for a vantage point. An empty commercial lot sat opposite the back of the warehouse. Weeds pushed through cracked concrete. Trent slipped through a gap in the chain-link fence and crouched behind a rusted skip bin.

From here, he had a clear view of the warehouse's rear yard.

Sitting in the yard was a dark blue FPV Pursuit ute. It had a hard tonneau cover and blacked-out rims.

Trent pulled his phone and took three rapid photos, zooming in on the licence plate. He texted them to Mac.

Target vehicle confirmed at location. Stand by.

He settled into the dirt behind the skip bin. The damp seeped through his jeans, mirroring the chill he'd felt in the park the night before. He watched the building.

At 6:30 AM, the heavy steel door at the back of the warehouse ground open.

Three men walked out into the yard.

Trent recognized the builds instantly. They were the men from the park. The one in the middle, Brett Holden, was a towering mass of muscle with a shaved head and a thick, tribal tattoo wrapping around his thick neck. He was wearing grey track pants and a tight black t-shirt.

The other two were younger, equally built, their faces hard and unsmiling. One of them was carrying a heavy canvas duffel bag. He tossed it into the back of the ute. It landed with a heavy, metallic clunk.

Holden leaned against the tray of the ute, lighting a cigarette. He said something to the younger guys. They laughed. It was a harsh, ugly sound in the quiet morning.

Trent watched them, his hand resting on the grip of his pistol. They were relaxed. Arrogant. They thought they were untouchable. They thought the city was their personal hunting ground.

His phone buzzed in his pocket. It was Mac.

"Talk to me," Trent whispered, keeping his eyes on the yard.

"Magistrate signed the warrants," Mac said. "We've got the green light. Harris is mobilizing the Tactical Operations Unit. They want to hit the gym at midday, when the bulk of the members are inside. Roll up the whole crew."

"No," Trent said instantly.

"Trent, it's the TOU. They run the entry."

"If they hit it at midday, it's a circus," Trent argued, keeping his voice dead level. "Holden is standing in the yard right now with his two lieutenants. The vehicle is here. The gear is here. If we wait six hours, we give them a chance to move the evidence. They're planning a hit for tomorrow night. They could load that ute and disappear before the TOU even finish their briefing."

There was a long pause on the line.

"What are you suggesting?" Mac asked carefully.

"I'm looking at three primary suspects in an active serial murder investigation," Trent said. "I have exigent circumstances. If I suspect they are moving evidence, I can move."

"Trent, do not go in there alone," Mac snapped. Her professional veneer dropped, replaced by raw panic. "They're geared up. It's a fortified building. You wait for the cavalry."

Holden dropped his cigarette and ground it out under the heel of his boot. He nodded to the other two. They turned and walked back toward the heavy steel door. Holden reached for the handle to pull it shut behind them.

They were going back inside. The door would lock. The opportunity would be gone.

"Trent?" Mac demanded over the phone.

"Get the TOU here now," Trent said. "I'll hold the perimeter."

He hung up, shoved the phone in his pocket, and stood up.

He knew it was stupid. He knew it violated every protocol in the manual. But he also knew the faces of the three dead men. He knew the fear in the park.

Trent cleared the chain-link fence in one smooth vault. He hit the pavement running, his boots silent on the concrete. He crossed the alleyway in three seconds flat.

Holden was just pulling the heavy steel door shut. The gap was closing.

Trent hit the door with his shoulder, putting all two hundred pounds of his weight into the steel.

The door violently jarred backward, slamming into Holden's face.

Holden stumbled, a shock of blood exploding from his nose. He staggered back into the dimly lit corridor of the gym, yelling in surprise.

Trent stepped through the doorway. He drew his Glock, raising it in a tight, two-handed grip, his eyes adjusting instantly to the low light.

"Police! Do not move!" Trent roared, his voice bouncing off the concrete walls.

The two younger men spun around. They were standing near a rack of heavy dumbbells. The one who had carried the duffel bag lunged toward a gym bag sitting on a bench.

"Hands away from the bag!" Trent ordered, tracking the movement with the front sight of his pistol. "Do it now, or I will drop you."

The kid froze, his hands hovering inches from the bag. He looked at the gun, then at Trent's eyes. He slowly raised his hands.

Holden was on his knees, clutching his face, blood pouring through his fingers. He glared up at Trent, his eyes burning with pure, unadulterated hatred.

"You're a dead man," Holden spat, blood bubbling on his lips. "You hear me? You're a dead man."

"Get on the ground," Trent said, stepping forward. He kicked Holden hard in the side of the knee. Holden grunted and collapsed onto his stomach. "Hands behind your back. All of you. Now."

The three men slowly complied, laying flat on the rubber matting of the gym floor.

Trent stood over them, the Glock held steady. The silence in the gym was broken only by Holden's heavy breathing and the steady drip of blood onto the floor.

He had them.

But as Trent looked down the dark corridor leading into the main gym floor, he heard the heavy, rhythmic thud of a dozen pairs of work boots running toward him from the back rooms.

There weren't just three of them in the building.

Trent backed up toward the steel door. He was alone. He was outnumbered. And the cavalry was at least ten minutes away.

The war hadn't started. Trent had just walked straight into the ambush.
