Robert Ludlum

Protocolo Sigma, El Robert Ludlum Spanish, Tra edition

El banquero norteamericano Ben Hartman llega a Zurich para pasar unas relajantes vacaciones en la nieve, invitado por un cliente que ademas quiere presentarle a su muy atractiva nieta. Y la fiesta parece completa cuando, en la puerta del hotel, se encuentra con Jimmy Cavanaugh, un viejo amigo de la universidad. El problema es que Jimmy lleva una pistola en la mano, y su objetivo parece no ser otro que el propio Ben. Mientras tanto, la agente del Departamento de Justicia de Estados Unidos Anna Navarro esta a punto de realizar un descubrimiento de lo mas inquietante: la muerte de once hombres de un extremo a otro del globo esta relacionada con una misteriosa palabra en clave, Sigma, cuyas raices se hunden en tiempos de la segunda guerra mundial. Momento en que sus jefes deciden retirarla del caso y sabotear su carrera. / American investment banker Ben Hartman arrives in Zurich for a ski holiday, the first time he's been back to Switzerland since his twin brother died there in a tragic accident four years earlier. But his arrival in Zurich triggers something far more sinister than his brother's fate. When Ben chances upon Jimmy Cavanaugh, an old college friend, Cavanaugh promptly pulls out a gun and tries to kill him. In a matter of minutes, several innocent bystanders are dead - as well as Cavanaugh - and Ben has barely managed to survive. Plunged into an unspeakable nightmare, Hartman suddenly finds himself on the run. Department of Justice field agent Anna Navarro is being stalked around the world by a relentless killer, managing to survive the killer's attacks only by a combination of luck, skill and her own quick wits. These attacks are somehow related to her current assignment: investigating the sudden - and seemingly unrelated - deaths of a number of very old men throughout the world. The only thing that connects them is a file in the CIA archives, over a half-century old, marked with the same puzzling code word: SIGMA. But someone or something is always seemingly one step ahead of her, the survivors are rapidly dwindling, and her own life is in ever increasing danger
