[close] On October 4, 1976, a brutal murder shocked the tiny island nation of Tonga. A young Peace Corps volunteer had been stabbed 22 times; another volunteer was identified at the scene, but despite the damning evidence against him, Dennis Priven was never convicted of any crime. A beautiful, free-spirited young victim; a brooding villain who carried a dive knife sheathed by his side; an exotic, Gauginesque setting: with material this sensational, it's surprising that the most compelling passages in American Taboo concern the inner workings of a government bureaucracy. But the Peace Corps was an integral part of Deborah Gardner's tragedy. According to Philip Weiss, their officials did everything in their power to hush up her murder, then funded the aggressive defense that helped Priven go free. Weiss's account captures an intriguing historical moment, when the Corps' initial spirit of idealism found itself besieged by political and financial pressures. But the book ! is marred by his breathless, run-on style, and the figure at the center of this story remains a cipher. Was Dennis Priven an evil genius who planned the murder—and his defense—to ensure he would escape punishment? Or was he, as a psychiatrist hired by the Peace Corps contended, a budding schizophrenic? Weiss' answer is regrettably perfunctory: "He was a brilliant madman allowed to stay too long in the wrong spot who had lost control and then manipulated everyone around him with coldness and creativity."
