Robert Ludlum

In 2000, the publication of The Prometheus Deception to glowing reviews, enthusiastic reader response, and over two months on the New York Times bestseller list proved that Robert Ludlum is the master of international thriller. After thirty years and an unbroken string of bestselling novels, Robert Ludlum is at the pinnacle of his craft, having set a standard that only he himself can surpass. Now, with The SIGMA Protocol, Ludlum raises the stakes yet again. American investment banker Ben Hartman--son of the legendary Max Hartman, who built a financial empire from less than nothing - is on a vacation trip to Switzerland when he is approached by a childhood friend, who promptly tries to kill Ben. Narrowly surviving the attempt on his life, Ben discovers that the body of his former friend - as well as all evidence of the confrontation - has disappeared. But the attempts against his life are just beginning. Anna Navarro, a U.S. government agent, is sent to surreptitiously look into a string of deaths and murders of old men around the world. The only thing the men have in common is an OSS file marked with the code word SIGMA. But as she investigates, she suddenly finds herself pulled off the case, declared rogue by her superiors, and the target of an all-out manhunt. Brought together by accident, Hartman and Navarro must uncover the secrets long-buried under the name SIGMA - truths that threaten everything they think they know about themselves, their families, and even history itself. Not only are their lives at stake and the lives of everyone they hold dear, but the very future of the world.
