Germany, 1945.

The war is over.

But something has survived.

When American intelligence officer Richard Calder arrives in the ruins of Hamburg, he is assigned a simple mission: recover a mysterious container hidden in Warehouse 14. Instead, he discovers a trail of forged documents, dead guards, Soviet agents, and a secret submarine preparing to leave Europe.

On board is a man known only as The Passenger.

He is not a scientist.

He is not a soldier.

Yet governments are willing to kill to find him.

As the submarine disappears into the North Sea, Calder and Soviet operative Sokolov become entangled in a dangerous game involving atomic archives, hidden networks, and a secret organization known only as MORGEN.

A gripping Cold War thriller filled with espionage, mystery, and post-war intrigue.

Perfect for readers of historical spy fiction, submarine thrillers, and intelligence operations.
