One day, while trying to straighten up her elderly father's apartment, Franks discovered Nazi military paraphernalia, inspiring the Pulitzer-winning reporter and novelist (Wild Apples
) to investigate what he really did during the Second World War. The painstaking inquiries are hampered by his reluctance to discuss his work in military intelligence, attached to the navy's Bureau of Ordnance. Some of that reluctance may have to do with the onset of dementia tearing away his memories, but he's also profoundly traumatized by some of his missions. In one moving passage, he is persuaded to describe his experience as one of the first American observers at a liberated concentration camp, every sentence still painful to get out even 50 years later. As Franks perseveres with her questions, she begins to understand how those experiences shaped their disintegrating postwar family life, but she acknowledges how difficult it is to achieve closure with this past, especially when she's afraid to confront the reality of his present condition. Even the most painful moments—as when she throws a particularly harrowing revelation back in her father's face to score revenge for adolescent resentments—are recounted with unflinching honesty as the military history takes a backseat to the powerful family drama.
