Fairy Fingers by Anna Cora Mowatt Ritchie (1819 - 1870)

Madelaine is the poor cousin of the aristocratic de Gramont family in France of the 1850’s. She is cherished by the beautiful young Bertha and secretly the beloved of the handsome Maurice, but she is barely tolerated by the haughty old countess. When her uncle’s scheming manages to cause a serious rift within the family, Madelaine finds she must rely on the skill of her “fairy fingers” and make her living as a seamstress. She winds up as the sought-after couturier “Mademoiselle Melanie” in Washington, D.C. and has an opportunity to help the now financially-imperiled de Gramonts. - Summary by Kelly S. Taylor
