John Le Carré - The Mission Song

Full of politics, heart, and the sort of suspense that nobody in the world does better, The Mission Song turns John Le Carre's laser eye for the complexity of the modern world on turmoil and conspiracy in Africa.
Abandoned by both his Irish father and Congolese mother, Bruno Salvador has long looked for someone to guide his life. He has found it in Mr. Anderson of British Intelligence. Bruno's African upbringing, and fluency in numerous African languages, has made him a top interpreter in London, useful to businesses, hospitals, diplomats - and spies. Working for Anderson in a clandestine facility known as the "Chat Room,"Salvo (as he's known) translates intercepted phone calls, bugged recordings, and snatched voice mail messages.
When Anderson sends him to a mysterious island to interpret during a secret conference between Central African warlords, Bruno thinks he is helping Britain bring peace to a bloody corner of the world. But then he hears something he should not have...
By turns thriller, love story, and comic allegory of our times, The Mission Song is a crowning achievement, recounting an interpreter's heroically naive journey out of the dark of Western hypisy and into the heart of lightness.
