Body on the Tracks — Barbara Schlichting

It's 1943. As a zephyrette, onboard a silver zephyr express train between Chicago and Denver, Brita is subject to over hearing a murder in Chicago's main train station. Was it German she heard? While the zephyr chugs across the country, another murder causes Brita to rethink the passengers loyalties. Is Brita too late to save the nation's food supply from the escaped Nazi? Will the undercover government agent assist her before she's the next victim? Will they resume their relationship afterwards?
