When the Brazilian military overthrew President Joao Goulart in 1964, American diplomats characterized the coup as a "100 percent Brazilian movement." It has since become apparent, largely through government documents declassified during the course of research for this book, that the United States had an invisible but pervasive part in the coup.

Relying principally on documents from the Johnson and Kennedy presidential libraries, Phyllis Parker unravels the events of the coup in fascinating detail. The evidence she presents is corroborated by interviews with key participants.
