A fascinating, and highly irritating with its content, book on the CIA's meddling in early 1960s Africa, focused on the first year of Congo's independence, and also including Ghana, whose president, Kwame Nkrumah, was a strong supporter of Congo's independence, and, of more challenge to the CIA, a leader of Pan-Africanism and of the non-aligned movement.
(Note: Semi-spoilers ahead but, because I'm not giving too many details, I'm not hiding them.)
Williams, who wrote a major book several years ago "reopening" the case that UN Secretary General Dag Hammarskjöld was murdered (more on that in a minute) focuses on the CIA's animus against Patrice Lumumba, the first prime minister of Congo. She presents clear details of how the Agency wanted him "gone" and how that came ultimately from Eisenhower himself. Even before Joseph-Desire Mobutu, the eventual Congolese dictator for more than 30 years from the mid-1960s, had Lumumba murdered, the US was looking at various possible assassination modes on its own. And, she indicates that CIA freelance agents likely were involved with luring Lumumba out of his Leopoldville statehouse in an attempt to escape, helped Mobutu track him down, and after he was captured, knew that Mobutu was going to transfer him to Katanga for his presumed eventual death.
On Hammarskjöld, Williams has good evidence that the so-called Katangan Air Force, almost certainly pilot Jan van Rissenghem, shot Hammarskjöld's UN plane down in Katanga six months after Lumumba's murder. But, that's not all. The "scramblers" for encrypting UN transmissions, not only from his plane, but from UN cables and wireless transmissions to and from UN headquarters, all had a "backdoor" on them, deliberately created for the CIA in conjunction with West German intelligence, already in the early 1950s. The Swiss company who made them was handsomely rewarded. Side note: Already at this time, Israel, while still waiting for more West German Holocaust blood money, was partnering with West German intelligence as well, including on this. So, too was "neutral" Sweden, Hammarskjöld's home.
Williams from there looks at CIA's increasingly harsh eye on Nkrumah, including backing the 1966 coup against him.
We also get a look at CIA front organizations like the Congress for Cultural Freedom.
Sidebars: The loathsomeness of American involvement against Lumumba, or at a minimum, ill will toward him, or Nkrumah, or an independent Congo, at the top levels includes not just Eisenhower, but in his administration, Dick Nixon, Douglas Dillon and others, and then, John Kennedy and his UN ambassador Adlai Stevenson among vaunted liberals. And, outside of electoral politics, names not generally seen in the past as CIA "cutouts" or whatever, like Jackie Kennedy Onassis' last squire, Maurice Tempelsman, make appearances.
