The Fourth Rule, by Douglass Seaver
The fog of war hides many secrets, but rarely a good one.
The Fourth Rule tells the story of one secret born when a Green Beret returns from Vietnam and disappears. Two decades later, the CIA approaches the soldier’s younger brother, Matthew Grant, to uncover what happened. Matthew denies knowing anything, but the CIA doesn’t believe him, and thus begins an intense struggle between the CIA, hell-bent on protecting its own and continuing its illicit clandestine activities, and a not-so-ordinary citizen, who has to risk it all to protect his secret and right a terrible wrong from the past.
