In December 1941, the Kuehn family had developed an active espionage program that provided the Japanese with information about US military forces in the Territory of Hawaii. This is their story, beginning in the mid-1930's and continuing through the 1960's.
Based on historical research, the story of a German family who lived in Hawaii and sold data to the Japanese. Fascinating how they lived among people and how they were initially caught and what they continued to do afterwards.
