The ‘queen of spy writers’ returns with another “wonderfully readable” espionage thriller about a sunken Nazi chest whose secrets reverberate throughout the decades . . . (New York Times)

He demanded the immediate dispatch of two suitably trained operatives to Salzburg. Extreme measures might be necessary.

In 1945, with their thousand-year empire falling around them and the Allies on their heels, the Nazis hide a sealed chest in the dark, forbidding waters of the Finstersee—a lake surrounded by the brooding peaks of the Austrian Alps. There it lies for 21 years, almost forgotten, until a British agent decides to raise it from the depths . . .
 
The secrets he uncovers are far-reaching and lethal, and in Salzburg, Bill Mathison—a New York attorney on the trail of a missing colleague—finds himself drawn into the shadowy underworld of international espionage. Not knowing who to trust amidst the chaos, he is drawn to two beautiful women, one of whom will betray him.
 
“All the makings of the big bestseller . . . Nazi secrets at the bottom of an Austrian lake, agents from America, Russia, Britain and Red China, some modern-day Nazis—and plenty of dead bodies.”
