Written in 1918, when the Zeppelin raids were real and the English coast was truly watched, E. Phillips Oppenheim's spy story is a quiet, domestic one, played out over dinner tables. A passenger is set down from a Zeppelin and walks into the house of a woman who must now weigh what she owes her country against what she owes an old and dangerous debt. This edition presents the complete and unabridged novel, newly typeset and illustrated with 35 full-page color plates.
