Peter Evan's biography of shipping tycoon Aristotle Onassis, Ari, met with great acclaim. Not long after the book appeared, however, Onassis's longtime business partner Yannis Georgakis hinted to Evans that he had missed the "real story." "I must begin," Georgakis said, "with the premise that, for Onassis, Bobby Kennedy was unfinished business from way back...."

His words launched Evans into the heart of a story that tightly bound Onassis not to Jackie's first husband, but to his ambitious younger brother Bobby. Nemesis reveals the tangled thread of events that linked Ari and Bobby, two of the world's most powerful men, in their intense hatred for one another and uncovers the surprising role played by the woman they both loved and the keeper of Camelot's flame.

Through extensive interviews with the closest friends, lovers, and relatives of Onassis and the Kennedys, longtime journalist Evans has uncovered the shocking culmination of the love triangle: Aristotle Onassis was at the heart of the plot to kill Bobby Kennedy. Meticulously tracing Onassis's connections in the world of terrorism, Nemesis presents compelling evidence that he financed the assassination--including a startling confession that has gone unreported for nearly three decades. Along the way, this groundbreaking work also daringly paints these international icons in all of their true colors. From Evans's deeply nuanced portraits of the charismatic Greek shipping magnate and his acquisitive iconic bride to his probing and revelatory look into the events that shaped an era, Nemesis is a work that will not be soon forgotten.
