Journalist Christine Kuehn joins us to discuss Family of Spies and her gripping emotional reckoning with her family’s shocking personal ties to Nazi espionage.
The book begins in 1994, when a single letter from a historian pierces Kuehn’s quiet suburban life, revealing a secret she never suspected. Kuehn discovered that members of her own family were Nazi intelligence agents. What follows is a thirty-year investigation that pulls from FBI files, government and family archives, photographs, correspondence, and interviews.
In today’s Book Gang conversation, Kuehn reflects on reporting on her own lineage, the ethical and emotional stakes of uncovering a truth that implicates the people who raised her, and how she structured the book across dual timelines to hold both the global history and her personal reckoning.
This episode airs the week of National Holocaust Remembrance Day. This moment calls us to remember not only the victims of Nazi violence, but also the systems, enablers, and silences that allowed it to spread. Christine now uses her research to support Jewish organizations, which you will hear about in today’s conversation as we unbox the past together.
In this emotional conversation, we explore:
- A letter that rewrote a life: Christine walks us through the 1994 moment that sent her on a decades-long quest for truth. We talk about disbelief, denial, and what it feels like to realize your family story is not the one you were told.
- Investigating your own inheritance: Drawing on her background as a journalist, Christine explains how her research methods evolved as new archives opened and technology advanced, how she assessed unreliable or conflicting memories, and what it was like to work alongside her husband while racing against her father’s dementia.
- Espionage hidden in plain sight: We unpack the book’s most chilling revelations. Nazi agents embedded in 1930s Hawaii, social fronts built on glamour and charm, and how everyday excess eventually drew the FBI’s attention.

BONUS BOOK LIST: This week’s companion book list features 22 Books About Spies that include both fiction and nonfiction titles to give Christine’s book a landing place. Patrons will receive printable checklists for their next visit to the library!
Family of Spies Book Summary
A propulsive, never-before-told story of one family’s shocking involvement as Nazi and Japanese spies during WWII and the pivotal role they played in the bombing of Pearl Harbor.
It began with a letter from a screenwriter, asking about a story. Your family. World War II. Nazi spies. Christine Kuehn was shocked and confused. When she asked her seventy-year-old father, Eberhard, what this could possibly be about, he stalled, deflected, demurred, and then wept. He knew this day would come.
The Kuehns, a prominent Berlin family, saw the rise of the Nazis as a way out of the hard times that had befallen them. When the daughter of the family, Eberhard’s sister, Ruth, met Nazi leader Joseph Goebbels at a party, the two hit it off, and they had an affair. But Ruth had a secret―she was half Jewish―and Goebbels found out. Rather than having Ruth killed, Goebbels instead sent the entire Kuehn family to Hawaii, to work as spies half a world away. There, Ruth and her parents established an intricate spy operation from their home, just a few miles down the road from Pearl Harbor, shielding Eberhard from the truth. They passed secrets to the Japanese, leading to the devastating attack on Pearl Harbor. After Eberhard’s father was arrested and tried for his involvement in planning the assault, Eberhard learned the harsh truth about his family and faced a decision that would change the path of the Kuehn family forever.
Jumping back and forth between Christine discovering her family’s secret and the untold past of the spies in Germany, Japan, and Hawaii, Family of Spies is fast-paced history at its finest and will rewrite the narrative of December 7, 1941.
