As the director of the Department of the Army's Central Identification Laboratory, Robert Dean "Kel" McKelvey has made a career solving some of the country's most complex identification cases. The CIL is responsible for identifying all U.S. war dead from battlefields old and new around the world. The caseload is endless, the endgame invaluable. Kel's work -- the examination of a bone or bone fragment -- may bring blessed closure to thousands of military families and loved ones left behind. But after fifteen years at the CIL, Kel is fast approaching emotional meltdown. And that's when he encounters his thorniest case yet: the recovery of Jimmie Carl Trimble, a soldier from Arkansas who died a hero's death during the Vietnam War. When a rare DNA sequence turns up at both the Army and FBI labs, it points to the unthinkable: a link between Trimble and a forty-year-old unsolved racial killing in the Arkansas delta. Partnered uneasily with the volatile FBI Special Agent Michael Levine, Kel must peel back decades of silence to reveal a complex web of stolen identity, betrayal, patriotism, collusion, and lies.

Taking readers deep inside the fascinating world of military and civilian forensic science, One Drop of Blood is a pitch-perfect thriller by a talented new author who knows the terrain better than anyone.
