The Gordian Knot — Bernhard Schlink

Georg Polger ekes out a lonely living as a freelance translator in the south of France, until he is approached by a certain Mr. Bulnakov, who has a intriguing proposition: Georg is to take over a local translation agency and finish a project left by the previous owner, who died in a mysterious accident. The money is right and then there is the matter of Bulnakov's secretary, Francoise, with whom Georg has fallen hopelessly in love. Late one night, however, Georg discovers Francoise secretly photographing a sensitive military project. He is shocked and heartbroken. Then, her eventual disappearance leaves him not only bereft, but suspicious of the motivations behind Mr. Bulnakov's offer. To make matters worse, Georg's every move is being watched. Determined to find out who Francoise really is, and to foil who ever is tracking him, Georg sets out on an mission that will take him to New York City, where with each step he is dragged deeper and deeper into a deadly whirlpool in which friend and foe are indistinguishable.
