A fictional portrayal of a real-life Revolutionary spy and her daring deeds, from the New York Times–bestselling author of The Only Woman in the Room.

Agent 355 is a result of author Marie Benedict’s quest to bring history’s most fascinating and courageous women to life for contemporary readers. Known to history only by her alias, this mysterious female spy, able to move freely and unobtrusively in loyalist circles, became a member of George Washington’s New York–based Culper Ring. This thrilling novella depicts who Marie Benedict thinks Agent 355 could have been, though her true identity remains unknown.

During the sweltering summer of 1779, eighteen-year-old Elizabeth Morris attends the social events of the British-occupied city, but the forced merriment holds no charm for her. She finds herself in the company of enemy soldiers, who think nothing of discussing matters of government and war in front of mere women. This invisibility becomes Elizabeth’s greatest asset as she offers her services to Robert Townsend, a Continental sympathizer. Her bravery will bring down one of the most notorious traitors in American history and ultimately seal her fate as a woman willing to sacrifice everything for love and country.
