Bruno "Salvo" Salvador, a half-British, half-Congolese interpreter finds himself caught in the midst of a political struggle in the Congo that highlights the downfall of "countries that choose to invade another for financial gain, cloaked in the language of establishing a just and democratic government." The Mission Song is John le Carre's 20th novel, and even without its eye towards current controversy on the world stage, is a compelling addition to the well known espionage author's body of work that spans the past 45 years.
