On a hillside overlooking Burnside Bridge—the focus of the Battle of Antietam—souvenir hunters find the unmarked grave of an unknown Union officer.

Don Spaniel, an archeologist in the National Park Service, is called in to examine the remains. He soon discovers that the officer was murdered and that his identification disk could not possibly belong to him, since its rightful owner is buried elsewhere. So who was this officer? Where did he come from? And why was he killed?

In a swift narrative deftly combining the past with the present, Jim Lehrer has created an engrossing story that will appeal to a wide variety of readers.
