It's the spring of 1918, and the Spanish Flu epidemic is killing soldiers and civilians alike. Battlefield nurse Bess Crawford is in France, caring for hundreds of influenza patients, as well as the wounded. There, she accidentally discovers concealed among the bodies waiting for the burial detail an officer who has been murdered. What's more, he was in her father's former regiment and a family friend.
Before she can report the body, she falls victim to the deadly flu herself. By the time she has recovered, the murdered officer has been buried, and the only other person who had seen the body has hanged himself. Or did he?
With only her father's connections in the military to help her, Bess must piece together what little evidence they have to find an elusive killer. And he already has Bess in his sights, determined to stop her before she uncovers his identity.
