Autumn 1943. American agent David Spaulding is among the global espionage elite who have converged on Buenos Aires. His top-secret mission can bring World War II to an explosive end. But what happens in this city of assassins, betrayals, and sensual encounters is the most sinister and terrifying deal ever made between two nations. Intense, high-level covert negotiations will soon bear dangerous fruit with the aid of expatriate German industrialist Erich Rhinemann. But suddenly the game changes, and Spaulding is the man caught in the middle. Struggling furiously to save his sanity, the woman he loves, and his very life, Spaulding might be the only one who can rescue the world from a shattering fate.   Praise for Robert Ludlum and The Rhinemann Exchange   “A superb plot filled with exciting chases, double crosses, secret codes, and beautiful women . . . a picture of the beastliness underlying the espionage world, a world of brilliance without scruples, brutality without restraint.” — Chicago Tribune   “A breathtaking pace . . . The plot is extraordinary.” — Bestsellers   “A paragon in the field.” — The New York Times
