Four U.S. intelligence agents play a high stakes game of international double-crossing, blackmail and deceit. One by one, they disappear - or die. And no one, not even their widows or the U.S. public, were ever told the truth.

Now, for the first time, three experienced investigators present a shocking case, based on hundreds of interviews and years of research, against the U.S. intelligence establishment: a case of incompetence, cover-up and even Soviet penetration. From the Chesapeake Bay disappearance of John Arthur Paisley, a suspected Soviet mole, to the gruesome torture death of Army Warrant Officer Ralph Sigler, here is a harrowing journey into a world of spies and counter-spies, where no one is what they seem.
