My sister called me at midnight and whispered, “Turn off every light. Go to the attic. Don’t tell your husband.” I thought she was losing her mind — until I looked through the floorboards....

The Port of Baltimore was a labyrinth of towering steel shipping containers, towering cranes, and dark, churning water. Cold fog hung thick over the harbor, swallowing the yellow lights of the industrial docks.

By 3:30 a.m., rain had reduced to a freezing drizzle.

A joint FBI and Coast Guard task force had completely sealed off Pier 42. Armed agents in tactical gear moved silently between the massive stacked shipping containers, their weapon-mounted lights cutting through the murky fog.

I sat in the back of the mobile command unit—a converted bus packed with satellite monitors, tactical radios, and digital tracking screens.

Noah was asleep on a small cot in the rear of the bus, wearing a pair of noise-canceling headphones provided by a friendly agent, clutching a stuffed bear.

Arthur Vance, the Deputy Director of the FBI’s Counterintelligence Division, stood over the main map terminal, glaring at the red grid overlay of Pier 42.

"The cargo vessel The Iron Siren is registered under a Panamanian flag," Director Vance reported, his voice crisp and authoritative. "She’s loaded with four hundred commercial containers. Her engines are idling, and her captain has refused to lower the gangway for federal inspection."

"He’s on that ship," Mara said, leaning over the console, pointing at a high-definition thermal imaging camera feed coming from a surveillance drone hovering above the dock.

On the screen, a lone human figure carrying a heavy black pelican case was moving rapidly along the high steel catwalk of a container crane, heading toward the upper deck of the cargo ship.

"That's Vane," Mara identified. "He’s trying to reach the ship's satellite communications dome on the bridge."

"We have snipers on the grain silo six hundred yards out," Director Vance said, picking up his radio microphone. "Alpha Team, do you have a target lock?"

"Negative, Command," a static-filled voice answered through the speaker. "The fog is too thick. We have thermal distortion from the ship’s exhaust stacks. We cannot guarantee a clean shot."

"If he reaches that bridge and connects the hard drive to the ship's high-frequency transmitter, the algorithm goes live in forty seconds," Mara warned, her face pale. "Once it hits the darknet, defense grids from NATO to Tokyo become vulnerable to remote override."

I stood up from my seat, stepping toward the main console.

"He won't use the ship's transmitter," I said clearly.

Director Vance and Mara both turned to look at me.

"What do you mean, Elise?" Director Vance asked.

"My father designed the guidance protocol," I explained, pointing at the technical schematics of the algorithm displayed on a secondary monitor. "The code is too heavy for standard marine satellite bands. It requires a localized signal amplification array—something with at least fifty gigahertz of bandwidth."

Mara’s eyes widened. "The crane."

"The container crane on Pier 42 has a private industrial 5G relay tower mounted at the very top," I said, my voice cold and focused. "He’s not going to the ship. He’s climbing the crane tower to use the dock's master transmitter."

Director Vance immediately grabbed his microphone. "Bravo Team! Redirection! Target is on the main crane structure!"

"He knows your tactical teams are on the ground, Director," I added, grabbing my coat from the back of the chair. "He’ll see them coming up the gantry stairs from a mile away. He’ll execute the transmission before your team reaches the second platform."

"Then how do we stop him, Elise?!" Mara demanded.
