"I Was Castro's Prisoner" is a historically significant book that in 1963 was a media sensation in conservative political circles. Author John Martino presented first-hand personal experience to virtually all the evils that had come with the Castro revolution. He offered descriptions of ongoing, brutal executions held "against the wall" and related stories of full-fledged warfare against both the capitalist and professional classes within Cuba. What Martino witnessed and was openly documenting were the very worst fears of the Cold War: the victory of communism in a capitalist country, and the subsequent destruction of a way of life for its people. Originally published in 1963, republished now to accompany new historical information on the possibility that Martino may have played a role in a conspiracy that resulted in the death of President John Kennedy. In later years, only months before his death, Martino confided that he served as a courier and had certain details regarding a conspiracy to kill JFK in Dallas. Martino was also prominent among those who provided purported evidence to prove Fidel Castro had been the moving force behind the accused assassin Lee Oswald. You will not find the details of what Martino did in 1963 in "I Was Castro's Prisoner"—what you will find is the reason he acted as he did.-Print ed.
