No Certain Rest

BONUS: This edition contains an excerpt from Jim Lehrer's Tension City . On a ridge 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?
