First published in 1918, while the Great War still raged overhead, The Zeppelin's Passenger is E. Phillips Oppenheim's gripping tale of espionage on English soil. When a German agent is delivered to the heart of the English countryside by one of the Kaiser's feared airships, a web of secrets, suspicion, and shifting loyalties begins to tighten around an English household — and around the woman who must decide where her heart, and her country's safety, truly lie. Blending wartime paranoia with romance and brisk, cinematic plotting, the novel captures the anxieties of a nation under threat from a new kind of war in the skies. This edition presents the complete, unabridged original text, faithful to the first edition, together with a new introduction and reader's notes illuminating the novel's historical context, its place in the golden age of spy fiction, and its enduring appeal.
