The Long goodbye

In the closing hours of the defense of Khe Sanh Combat Base, the longest and bloodiest battle of the Vietnam War, Tom Mahoney inexplicably walked away from his platoon, unarmed, and was shot to death by enemy soldiers hiding nearby. His fellow Marines made several desperate attempts to recover their well-liked comrade, but were finally forced to leave him behind--though never forgotten. Author Michael Archer (a high school friend who joined the Marines together with Tom) chronicles his exhaustive search for answers to his friend's mysterious stroll into oblivion. This quest eventually leads to an improbable series of connections: from Tom's childhood friends, to fellow Marines, past the frustration of numerous ineffective, often inept, attempts by the U.S. government to locate his remains and eventually back to that infamous battleground and the last remaining eyewitness to Tom Mahoney's death--one of those who killed him.
