Dr. Abbott, now an historian, worked as a Reuters reporter in Haiti during much of the Duvalier period (1957-86) and was, in fact, the wife of the brother-in-law of General Henri Namphy, subsequent president of the country. This familial connection does not, however, appear to affect her treatment of Namphy except perhaps to humanize the criminal.
François Duvalier is also treated humanely. As a young doctor and published ethnologist, he was a decent fellow, a follower of his predecessor, the unusually competent Dumarsais Estimé, and was likely really popular when "elected". Soon, however, facing opposition and a restive, impoverished population, he transformed into a superstitious monster, having himself annointed "President for Life" and naming his own successor, his son Jean-Claude Duvalier.
While the elder Duvalier was personally materially moderate and well-educated in some respects, the son was an uneducated playboy when he assumed power at the age of eighteen. While the father was politically savvy, albeit bloodthirsty and sadistic, the son was naive. Unfortunately, the corrupt officials and businesspersons who had benefitted from his father's rule, continued under his and, with less supervision by their ostensible leader, exercised their power to extend their ability to rob the treasury and exploit the people.
Jean-Claude's involvement in politics much increased upon his marriage to Michèle Bennett Pasquet, a very willful divorcée whose family members were quick to take advantage of their newfound position in society. Abandoning his father's philosophy of negritude, Jean-Claude was substantially dominated by his spendthrift wife and her mulatto relations, increasing demands on the public purse and further immiserating the country.
Ultimately, of course, it came to an end...sort of. The next government, that, effectively, of the army, was little better and the hopes of the masses had been raised. The book ends in 1990 with a quotation from a young activist Catholic priest, Jean-Bertrand Aristide, later (1991) to become Haiti's first really elected president until overthrown twice, the second time (2004) at least with the connivance of the United States of America, long a meddler in Haitian affairs.
Given the recent earthquakes and today's report of over 200,000 dead in Haiti, this readable and darkly entertaining history is probably due for a new, hopefully expanded, edition.
