Robert Ludlum's trademark skills of intricate plotting, breakneck pacing, and high-wire drama are all on display in this gripping thriller. After his twin brother dies in a plane crash, Ben Hartman reluctantly takes his place in the investment firm started by their father, a Holocaust survivor. But then an old college buddy tries to kill Ben on a crowded Zurich street, setting off a chain of events that ultimately leads Ben into the thick of a worldwide … mehrconspiracy. Behind it is Sigma, a multinational cartel built on the rubble of World War II by industrialists and financiers bent on exploiting wartime technology and protecting their wealth from the threat of communism. Accompanied by a beautiful American justice department agent, Ben eludes the assassins on his trail and follows Sigma's tentacles across Europe, to Brazil, Washington, and finally to a sanitarium known as the Clockworks in the Austrian Alps, where the horrifying agenda of a perverted new world order is revealed. Ludlum, who died between the writing and publishing of this book, was a master of the genre he helped popularize, and The Sigma Protocol shows him at the peak of his craft. --Jane Adams weniger
