THE SECOND OSWALD has been called "the first plausible and significant argumentation on the Kennedy assassination." It takes into account the books by Edward J. Epstein, Mark Lane and Harold Weisberg. Too much was attempted too quickly. Professor Popkin believes that Lee Harvey Oswald may have been innocent and no more than a decoy in a plot to kill the President. His job may have been to divert suspicion and be arrested. A startling alternative to the 'Single Assassin' theory. For an author bio and photo, reviews and a reading sample, visit bosonbooks.com.
