Do you think you know what really happened after World War II? You don't. Sigma made sure of that.

American investment banker Ben Hartman arrives in Zurich, the first time he's been back to Switzerland since his twin brother died there in a tragic accident four years ago. But when Ben chances upon Jimmy Cavanaugh, an old college friend, Cavanaugh draws a gun and tries to kill him. In minutes, several innocent bystanders are dead, as well as Cavanaugh, and Ben is on the run, plunged into an unspeakable nightmare.

U.S. Department of Justice field agent Anna Navarro is being stalked by a relentless killer, managing to survive only by a combination of luck, skill, and her own quick wits. The attacks on her are somehow related to her current assignment: investigating the sudden, seemingly unrelated deaths of a number of very old men around the world. The only thing that connects them is an ancient CIA file bearing the code word Sigma.

Brought together by accident, Ben and Anna realize that their only hope of survival lies with each other. Together they race to uncover the long-hidden diabolical secrets of Sigma - secrets that threaten everything they think they know, everything they believed about their friends and families, everything they were taught about history itself. For behind Sigma lies a vast deception that is finally coming to fruition - and the fate of the world is in their hands.

    " I love reading Robert Ludlum because he takes me around the world time and time again. I specifically liked this book and when I first started reading I thought to myself,"this guy must have gone, and seen everywhere and everything." Low and behold he happened to mention in the first couple chapters a little bitty town about 10 miles from me White Sulpher Springs, NY and I'm telling you if you sneeze you would miss this town. So Robert Ludlum had truly been everywhere. Now about the book...OMG it starts off completely action packed, our good guy steps out of his hotel and sees an old college chum he hadn't seen in years and instead of a pat on the back and a good catching up this guy is trying to kill him and he has no idea why. What a great read...Mr Ludlum has yet to let me down. "
