Witness to Evil — Janet Dawson

Private investigator Jeri Howard can scarcely believe that someone is actually paying her to go to Paris, even if it is only to fetch a wild teenager home. But the wanderer, eighteen-year-old Darcy, turns out to have a serious reason for her unauthorized jaunt: to visit Holocaust memorials and to meet the French family who sheltered her grandmother as a girl from the Nazis. But back home in California, Darcy stumbles on evidence that Nazism is alive and well in the terrifying present. And Jeri has the deadly work of trying to extricate Darcy from the frightening consequences of her discovery.
