Occupier by Gilbert R. Gibbons

Nineteen-year-old Private Don Orso finds himself in Inchon, Korea in early spring 1946 during the Korean Occupation.

As he struggles to find his way in a foreign culture, Orso soon makes friends and turns the heads of some important officers who notice Orso's knack for investigation and getting down to the facts.

He is assigned a suave Korean translator who introduces him to the lovely Embee Park.

Priorities shift when Orso is ordered to broaden his investigations with a more experienced interpreter.

Based on a story that couldn't be revealed for 50 years.
