Angry at being rejected for military service, Minister Tyrell Walker accepts the call to serve as a civilian spy within his own country. Across the river from Cincinnati, Ohio, a spy working for a foreign country is stealing secret plans for newly developed ammunition to be used in the war. According to Tyrell's FBI cousin, this spy favors pink stationery giving strong indications that a woman is involved. He's instructed to obtain a room in the Rayner Boarding House run by the lovely, spunky red-haired Emma Jaine Rayner. Sparks of jealousy and love fly between them immediately even as they battle suspicions that one or the other is not on the up and up. While Tyrell searches for the murdering spy who reaches even into the boarding home, Emma Jaine struggles with an annoying renter, a worried father (who could be involved in this spy thing), and two younger sisters who are very different but just as strong willed as she is. Tyrell works to keep his double life a secret and locate the traitor. He refuses to believe that Emma Jaine could be involved even when he sees a red-haired woman in the arms of another man. Could the handsome and svelte banker who's also determined to win Emma Jaine's hand for marriage, be the dangerous man he's looking for? Is the trouble-making renter who hassles Emma Jaine serving as a flunky? Worse, is Papa Rayner so worried about his finances and keeping his girls in the style they're used to, that he'll stoop to espionage? Will their love survive the danger and personal issues that arise to hinder the path of true love?"
