The Interpreter's Secret — Andrew Rosenheim

When State Department interpreter Weaver is summoned to an off-the-books meeting during a G20 summit, he expects routine diplomacy. What he gets is a chilling glimpse into a secret arrangement between the White House and the Kremlin -- an arrangement that could destroy lives, careers, and nations. With only a red digital pen as evidence and a growing sense that he was never meant to walk away from that room, Weaver flees to the safety of England.

But there is no safety.

Hunted by invisible forces and unsure whom to trust, he must uncover the truth before the truth consumes him. The Interpreter's Secret is a taut, sophisticated literary thriller about power, language, and the dangerous things left unsaid.
