If Gerald Posner’s book, Case Closed — Lee Harvey Oswald and the Assassination of JFK (1993), convinced me that Lee Harvey Oswald killed JFK and acted alone, Reclaiming History — The Assassination of President John F. Kennedy by Vincent Bugliosi (2007) removed any possible lingering doubts that I may have had, even subconsciously.
Case Closed — Lee Harvey Oswald and the Assassination of JFK by Gerald Posner is the definitive book on the JFK assassination. Case Closed is duly named as an authoritative and definitive treatise on the subject. The book is well investigated, well written, and thoroughly convincing because of the meticulous research and persuasive, logical narrative of the accomplished author Gerald Posner, a former Wall Street lawyer.
Passport to Assassination: The Never-Before-Told Story of Lee Harvey Oswald by the KGB Colonel Who Knew Him by Oleg Nechiporenko is a disappointing book for an intriguing subject!
