Dom Combe presents the reader a sharply focused profile of a dedicated and extraordinary woman of the 20th century, Henry James'sister-in-law, independent in spirit and passionately devoted for more than 60 years to the cause of Gregorian Chant and its liturgical implementation. Drawing on her voluminous correspondence, he traces the main events of her life following her conversion in 1904 to the Catholic Church. From these letters emerges the clear image of a fiercely strong-willed and gracious woman who pursued her ideals with relentless zeal.
