In 1961 the Congo was in crisis, fragmented and at war with itself. The streets of Leopoldville, the capital, were crawling with CIA operatives, MI6 agents and Soviet infiltrators. Belgian colonialists, Rhodesian white supremacists and corporate mercenaries massed in the south of the country. The chaos conspired to make it one of the most dangerous places on Earth.

UN Secretary General Dag Hammarskjöld, the man John F. Kennedy called 'the greatest statesman of our century' flew into the maelstrom. He was an idealist. The Congo's best hope for peace and independence. But en route to a diplomatic summit to reunite the country, Hammarskjöld's plane mysteriously disappeared. Soon afterward he was discovered dead in the smoking wreckage, an Ace of Spades playing card placed on his body.
