Deep in the Hausruck Mountains of Austria, there is a remote hideaway—the fortress-like nerve center of an ominous movement, the Brotherhood of the Watch. American agent Harry Latham has penetrated the movement, a neo-Nazi organization that was born in the days after the Third Reich's defeat and whose deadly tentacles have spread to the United States and beyond. Now, after three years in deep cover, and on the eve of his most spectacular success, Harry Latham has disappeared.

Drew Latham, Special Officer for Consular Operations in Paris, is frantic to discover his older brother's fate. But when he receives the sudden good news that Harry has surfaced, gut-twisting doubts arise. Has Harry's cover been blown? And if so, why has the Brotherhood of the Watch let him live?

For Harry Latham has emerged with an explosive list: the secret supporters of the movement, among them some of the highest-ranking officials in the United States and its allies, names synonymous with honorable service to their nations. It is a document that could topple governments—but is the list legitimate? Can Drew Latham trust his own brother?

To find the answer, Drew Latham decides to take on his brother's identity, stepping directly into the crossfire between the assassins gunning for Harry Latham—and those who want Drew himself dead.

From a hushed Alpine valley to the backstreets of Paris, from the ruling chambers of Washington and London to the casinos of Monte Carlo, The Apocalypse Watch is vintage Robert Ludlum, a superb international thriller from the writer who created the standard for a new kind of entertainment.
