After discussing the Fromes, the significance of the munitions company, circumstances of the murder, and modus operandi of the spy network, Richmond offers a plausible theory of why the Fromes were killed. He provides ample “atmospherics” of the era, such as the cost of a Packard car, and what the Fromes might have listened to on the radio during their trip. The result makes for a well-paced, engrossing true crime story.
