[Ethan’s POV]

The alleys of Sector 4 were a labyrinth of broken concrete, rotting garbage, and suffocating darkness.

I pulled Claire around a sharp corner, my boots splashing through a deep puddle of stagnant water. Behind us, the shouts of the Lupii thugs echoed off the brick walls, accompanied by the sweeping, erratic beams of their flashlights. They knew the terrain better than we did. They were hunting in their own backyard.

"Keep your head down," I hissed, pressing Claire against the cold, wet brick of a narrow alcove.

I peeked around the edge. Two men were jogging down the main thoroughfare, sweeping their lights across the doorways. One of them was holding a heavy, short-barreled shotgun.

Flashback - Sixteen Months Ago

The rain in upstate New York was freezing, turning the Aegis Solutions tactical training ground into a sea of mud.

I was lying flat on my stomach beneath the rusted chassis of an old pickup truck, my breathing shallow, my muscles screaming from exhaustion. I had been running for three hours.

Footsteps crunched in the gravel nearby.

"You run like a civilian, Ethan," a voice called out. It wasn’t Darius this time. It was Graves, a former SAS operative and one of the lead instructors we had inherited when Vanguard absorbed Aegis. He was walking casually through the mud, a thermal monocular in his hand.

"Civilians run away from the threat," Graves continued, his boots stopping three feet from my face. "They run in straight lines. They panic. They look for the fastest route out. And that makes them entirely predictable."

Graves crouched down, peering under the truck. He didn’t even need the thermal optics. He had tracked my footprints.

"If you are being hunted by a superior force, you do not outrun them," Graves said, his voice a calm, clinical rasp. "You out-think them. You break their line of sight, you change your elevation, and you become part of the concrete. You let them run right past you. Evasion isn’t about speed. It’s about geometry."

...

Present Time

I pulled my head back from the edge of the brick wall. The Lupii were getting closer. Running down the alley would just put us in their line of sight. We needed to change our geometry.

I looked up. The fire escape of the adjacent tenement building had collapsed, but the rusted iron ladder was dangling about nine feet off the ground.

"Up," I whispered to Claire, pointing at the ladder.

I holstered my Glock, laced my fingers together to form a step, and braced myself against the wall. Claire didn’t hesitate. She stepped into my hands, and I hoisted her upward with a sharp grunt of effort. She grabbed the rusted iron rung, her boots scrambling against the wet brick until she pulled herself onto the landing.

I took a few steps back, took a running start, and jumped, catching the bottom rung. The metal groaned in protest, raining flakes of rust into my eyes, but it held. I hauled myself up just as the beams of the Lupii flashlights swept into the alley below.

Claire and I pressed ourselves flat against the iron grating of the landing, holding our breath.

"Where did they go?" one of the thugs growled in Romanian, his flashlight beam cutting through the rain just inches below our boots.

"Check the basements," the man with the shotgun ordered. "They couldn’t have gotten far. The boss wants the American’s head, and he wants the people who helped him."

They jogged past us, their heavy footsteps fading into the storm.

I let out a slow, controlled exhale. "Come on. We need to get off the street."

We climbed two more flights of the fire escape until we found a window with a shattered pane. I reached through, unlatched the lock, and pushed the heavy wooden frame up. We slipped inside, dropping into the pitch-black interior of an abandoned apartment.

The air inside was stale, smelling of mildew and old dust. I drew my flashlight and swept the room. Stripped floorboards, peeling wallpaper, and a few pieces of broken furniture. It was empty.

"We’re clear," I said, moving to the window and pulling the rotting curtains shut to block any light from spilling out into the street.

I turned back to see Claire already sitting on the floor, her back against the wall. She was soaked to the bone, her blonde braid plastered to her neck, but she wasn’t resting. She had the reinforced briefcase open on her lap.

She pulled out the battered laptop and pressed the power button. The screen remained dead.

"Battery is fried," she muttered, tossing it aside. She reached into the briefcase and pulled out the stack of Jake’s notebooks.

I walked over and crouched beside her, keeping my voice low. "Claire, we can’t stay here long. As soon as the sun comes up, this sector is going to be crawling with syndicate guys looking for the bounty on our heads. We need to figure out where Jake went."

"I know," she said, clicking on a small penlight and holding it between her teeth. She opened the first notebook. "That’s what I’m looking for."

I looked over her shoulder at the pages. In the dim beam of the penlight, the writing looked like the frantic scribblings of a madman. The pages were completely covered in numbers, arrows, and jagged, aggressive handwriting. There were newspaper clippings taped to the margins—financial sections from German, French, and Romanian papers, all heavily redacted with black marker.

"It’s gibberish," I said, a heavy weight settling in my chest. "Darius was right. His mind is gone."

"No," Claire said, her voice suddenly sharp. She took the penlight out of her mouth. "No, Ethan, look closer. You’re looking at the mess. Look at the structure."

She pointed to a dense block of numbers on the left page.

"We majored in economics, remember?" she said, her eyes scanning the data with a terrifying intensity. "This isn’t random. These are shipping tonnages. He’s tracking the maritime freight volume out of the Port of Rotterdam."

She flipped the page. More numbers, cross-referenced with dates and times.

"And this... this is the fluctuating interest rate of the European Central Bank over the last eighteen months," she whispered, her finger tracing a jagged line graph drawn in blue ink. "He’s cross-referencing the maritime shipping delays with the ECB’s liquidity injections."

I stared at the pages, the realization slowly dawning on me. "Isabella Vane."

"Exactly," Claire breathed, looking up at me, her eyes wide with awe. "Isabella controls the ECB. She controls the ports. Jake hasn’t been hiding in the dark, Ethan. He’s been watching her."

"But how?" I asked, gesturing to the filthy, abandoned apartment around us. "He doesn’t have his network. He doesn’t have his servers. He’s living in a slum without Wi-Fi."

"He’s doing it analog," Claire said, her voice trembling slightly as the sheer magnitude of Jake’s intellect became apparent. "He’s stealing physical newspapers. He’s listening to public radio broadcasts. He’s taking delayed, fragmented, public data, and he’s running the predictive models in his head."

A chill ran down my spine that had nothing to do with the freezing rain.

Two years ago, when Jake absorbed the Oracle, we thought he still needed a massive, multi-billion-dollar digital infrastructure to process it. We thought the servers and the network were what made him a king.

We were wrong.

The network was just a tool. Jake’s mind, coupled with the Oracle, was the real weapon. Even fractured, bleeding, and stripped of every digital advantage, he was still fighting a shadow war against the most powerful woman in Europe using nothing but a stolen pencil and a notebook.

"He’s a monster," I whispered.

"He’s a survivor," Claire corrected fiercely. She flipped to the very back of the notebook. The pages here were stained with dried blood. "If he’s tracking Isabella, he must have a plan. He must have a secondary location."

She scanned the final pages, her eyes darting back and forth.

"Here," she said, tapping a line of text buried in the corner of the page. "He wrote this down three times. It’s not a financial equation. It’s an address. Strada Fierului, 42. Dr. Grigori."

"A doctor," I said, my pulse quickening. "He was bleeding heavily when he left the laundry facility. He wouldn’t go to a public hospital. He’d go to a black-market clinic."

"Strada Fierului is the Iron Street," Claire said, pulling up the offline map on her encrypted phone. "It’s an old industrial sector about three miles from here. If he’s hurt, that’s where he’s going."

I stood up, checking the magazine in my Glock one last time before racking the slide. The metallic clack sounded loud in the empty room.

"Then that’s where we’re going," I said.

Claire packed the notebooks back into the briefcase and stood up, her expression hardened. She didn’t look like a corporate logistics manager anymore. She looked like a soldier.

"Ethan," she said quietly as we moved toward the door. "The men in the boiler room... the ones Jake fought."

"Yeah?"

"They were armed," she said, her voice tight. "And Jake didn’t have a gun. He took them apart with his bare hands."

I thought about the man pinned to the brick wall with a piece of rusted rebar. I thought about the feral, empty look in Jake’s eyes when he stared down at us from the catwalk.

"I know," I said, pushing the apartment door open and stepping out into the dark hallway. "Let’s just hope he remembers who we are before we catch up to him."
