World War I, rural Pennsylvania. When innocent Hilda Lessing takes a job on a quiet truck farm, she never imagines she’ll uncover a deadly German spy ring plotting to cripple America’s war effort. One overheard conversation, one stolen suitcase, and one desperate leap onto a moving train turn an ordinary girl into the nation’s secret weapon. Pursued by ruthless enemies, guided by faith and a mysterious red signal, Hilda must reach Washington before it’s too late—for her country… and for the young officer who has captured her heart. Grace Livingston Hill’s thrilling blend of suspense, clean romance, and unwavering faith reminds us that even in the darkest hours, courage and prayer can change the course of history.
