"They’re going to burn the building down," Julian said, his eyes scanning the apartment for an exit. "We have to leave now."

"No," I said, my mind racing. "If we run, we’re just targets in the street. We need to disappear into the only place they can't track us: the city's decommissioned utility tunnels."

"The tunnels?" Julian looked at me like I was insane. "That's a death trap."

"It's an infrastructure I managed for three years," I said, grabbing my bag. "I know every bypass, every emergency shut-off, and every blind spot. They might control the government, but they don't control the sewer architecture."

We sprinted out of the apartment just as the elevators dinged on the floor. We took the service stairs, moving down into the bowels of the building. The city was a maze of concrete and shadow, and I knew how to navigate it better than anyone.

We reached the street level, but the sirens were already wailing. Not police sirens—these were tactical, deep, and menacing. Armored vehicles were rolling down the avenue, blocking off all exits.

"They're not even pretending to be police anymore," Julian noted, watching from the alleyway.

"They don't have to," I said. "We’re already dead in their files."

We dropped down into a storm drain, the water cold and smelling of iron. I led the way, my flashlight beam catching the rusted pipes and old conduits that stretched for miles beneath the city.

"Where are we going?" Julian asked, his voice echoing in the tunnel.

"To the primary junction," I said. "If I can tap into the city’s main power grid, I can cause a blackout that will kill the tracking systems for a ten-mile radius. It’ll buy us time to move."

"And then?"

"And then we find the people who are really in charge," I said, a dangerous fire growing in my chest.

As we walked, I noticed something on the wall. A mark. A small, blue symbol that looked like a bird in flight. It was the same symbol I had seen on the contracts in the Mercer safe.

"Julian, look," I whispered, pointing to the wall.

He leaned in, his flashlight illuminating the mark. "That's not just a symbol. That's a waypoint. Someone has been through here recently."

"Not just recently," I said, examining the dust. "These markings are fresh. Someone is leading us."

We followed the trail, winding through the tunnels until we reached a massive chamber beneath the city center. In the middle of the room sat a single, solitary chair. And sitting in the chair, waiting for us, was a person I never expected to see again.

It was Richard Mercer.

He looked older, tired, and his arm was in a sling, but it was definitely him. The man who had supposedly died of a stroke.

"Hello, Emma," he said, his voice raspy but calm. "I hope you brought the files."
