Bradley Earl Ayers was intimately involved in the CIA's war against Castro. In 1976 he wrote The War That Never Was

In a letter to Jack Anderson (1st March, 1995) he wrote:

Despite the obstacles and distractions, I have persevered in my effort to make known that information from my service with the CIA that I believed was relevant to the Kennedy assassination and that I felt the American people had a right to know. Naively, I wrote a book, THE WAR THAT NEVER WAS, which was published in 1976, expecting that my manuscript would make a contribution to the growing body of evidence pointing to a conspiracy in the President's death. I have recently learned that the managing editor at the publishing house was on the CIA payroll, intercepting and censoring books that might be damaging to the Agency.

Now he is preparing to tell all in The Zenith Secret which is scheduled to come out in December of this year. For a peek at what the book will contain, here is what he told John R. Tunheim, of the Assassination Records Review Board in a letter of August 23, 1994:
