Though the Rhodesian government blamed pilot error, Susan Williams shows their investigation suppressed and dismissed critical evidence. Though a subsequent United Nations inquiry could not rule out foul play, it had no access to the evidence to prove it. For the first time, Williams conducts a tense and often dangerous investigation into the Secretary-General's death, consulting sensitive materials in Zambia, South Africa, Sweden, Norway, Britain, France, Belgium, and the United States, including a secret trove of damning documents and photographs. At the heart of her exposé is Hammarskjöld himself, a courageous and complex idealist who sought to protect newly independent nations from the predatory impulses of the Great Powers. Williams reveals how conflict in the Congo was driven less by internal divisions than by the determination of western forces to keep real power out of the hands of postcolonial governments. She also demonstrates the extent to which Rhodesia's British settlers would go to secure white minority rule.
