Seventy-five years ago, one of the highest-ranking U.S. officers to serve behind enemy lines vanished in northern Italy. Major William V. Holohan of the Office of Strategic Services was leading a secret mission in a mountainous lake district where partisans were rising up against the Nazis. On the night of December 6, 1944, the mission’s surviving members reported an enemy attack that forced them all to flee in pitch darkness. By daybreak, only the major remained missing. Rumors of his capture spread throughout the region.

After northern Italy’s liberation, an Army investigator solved one of World War II’s enduring murder mysteries. This book brings that shocking evidence to light for the first time.
