A young Latin tutor --- penniless and bullied by a violent father --- falls in love with an extraordinary, eccentric young woman. Agnes is a wild creature who walks her family’s land with a falcon on her glove and is known throughout the countryside for her unusual gifts as a healer, understanding plants and potions better than she does people. Once she settles with her husband on Henley Street in Stratford-upon-Avon, she becomes a fiercely protective mother and a steadfast, centrifugal force in the life of her young husband, whose career on the London stage is taking off when his beloved young son succumbs to sudden fever.
