Antonia Moreson is the daughter of a respected physician living in Kent. When her father is called away on another case, she becomes responsible for an ill soldier, a Captain Lord Robert Quentin, the Earl of Gramsham. Through a long night of intensive nursing, the attractive officer makes an indelible impression on Antonia's heart. She longs to become a physician like her father, but she knows females are permitted only midwifery, not the study or practice of medicine. Antonia takes all the correspondence courses available, but she must take her final courses in person. So she disguises herself as a male. Years later, one of her Waterloo patients is comatose Captain Lord Robert Quentin, very ill, in danger of losing his leg, and threatened by a nearly unseen evil in the Royal Hospital. Antonia's disguise has worked well but now she has fallen in love with her patient. She can reveal her sex and destroy her potential career or she can forsake romance. Whether medicine and love can both triumph under such circumstances is the story of "Antonia's Daring Deception."
