Here are more former agents who have written books:
The CIA and the Cult of Intelligence written by
Victor Marchetti who was Deputy Director of the CIA
How I participated in the CIA-Mafia Murder of President Kennedy was written by Robert Morrow who is a former CIA agent.
Rearview Mirror: Looking Back at the FBI, the CIA and Other Tails was written by Bill Turner, who is a former FBI agent.
And then there is
E. Howard Hunt (a name you should know), who gave this deathbed confession:

Rolling Stone had an article about it as well:

An interesting bit of history between two of these individuals:
http://en.wikipedia.org/wiki/Victor_Marchetti
In 1976 Marchetti published "Foreign and Military Intelligence" and in 1978 he published an article about the JFK assassination in the far-right newspaper of the Libery Lobby, The Spotlight. Marchetti claimed that the House Select Committee on Assassinations revealed a CIA memo from 1966 that named E. Howard Hunt, Frank Sturgis and Gerry Patrick Hemming in the JFK assassination. Marchetti also claimed that Marita Lorenz offered sworn testimony to confirm this.
In 1981, E. Howard Hunt sued the Liberty Lobby and Marchetti for defamation and won $650,000 in damages. Liberty Lobby appealed the case with lawyer, Mark Lane. Marchetti, Liberty Lobby and Mark Lane won the appeal in 1995. Mark Lane wrote a book, "Plausible Denial", to describe the unfolding of that historic trial.
And now as you heard in the recording above, E. Howard Hunt has confessed to being involved.
So what is your next step in this argument? Of course it is to claim that these individuals didn't really work for the CIA or FBI. Too bad a couple of them like Hunt (one of the watergate burglars) and Marchetti (Deputy Director of the CIA) were extremely high profile guys.
