Louis and Beau L’Amour present a collaboration across time, an epic novel of Cold War suspense—a pair of unlikely heroes, a woman without a name, and the undefeated agents of the Third Reich find themselves locked in a deadly race to control the greatest secret of the twentieth century.

“I tip my hat and bow to the amazing talents of Louis L’Amour and Beau L’Amour.”—C.J. Box, #1 New York Times bestselling author of The Crossroads

“A masterful Cold War adventure.”—Elliot Ackerman, New York Times bestselling author of Sheepdogs

1961. The world is on the brink of nuclear war. Empires are crumbling. And in Barcelona, chaos is unleashed when a rogue officer of the East German Stasi attempts to blackmail a pair of struggling arms dealers. The secret—thirty tons of stolen gold hidden in an icebound wilderness at the end of the world.

Mike Fowler is a former Navy salvage diver and OSS assassin. Anton Voss is an expatriate German scientist whose past grows darker the closer anyone looks. Once they might have been enemies, yet the two share an inseparable bond: They have saved each other’s lives. But all of that is put at risk when Mike discovers Anton standing over a midnight visitor with a gun in his hand.

Now they’re on the run, allied with gangsters, pursued by the CIA, Israeli intelligence, and a shadowy cabal bent on creating an invisible empire. The trail leads from the rain-soaked docks of Marseilles to the futuristic towers of Caracas and the ruins of a secret island laboratory in Argentine Patagonia. The only way for Mike Fowler to save his oldest friends, and the woman he loves, is to unlock a decades-old mystery buried in his partner’s Nazi past . . . before it destroys them all.

Includes a special postscript by Beau L’Amour detailing the history of the original unpublished manuscript and the process of collaborating with his father both before and after his passing.
