Family of Spies

Family of Spies: A World War II Story of Nazi Espionage, Betrayal, and the Secret History Behind Pearl Harbor by Christine Kuehn

Grandpa was Nazi spy with interesting history in Hawaii. There were rumors of "baby spy" in the family that would go try to get intel. This book is part memoir and part family history. The author explores the skeletons in his family's closet. They were raised as an all American family. However, Grandpa was executed as a spy. (Though the family gives other reasons for what happened.) The book is an interesting exploration of interrelated bits of World War II history.
