Mary and Mr. Eliot is a twin portrait of T. S. Eliot and its author, the formidable Mary Trevelyan.

In 1938 T. S. Eliot, already "a Classic in his lifetime," struck up a friendship with Mary Trevelyan. This passionately curious woman, an intrepid traveler who, like Eliot, was deeply involved in the affairs of the Church of England, served as the warden of the Student Movement House, mere yards from the poet and editor's office at Faber and Faber.

Their relationship was domestic rather than artistic, characterized by churchgoing, conversation, record-playing, day trips to the English countryside with Mary at the wheel of the car Tom bought her, and Eliot cooking up sausages in his shirtsleeves. Over the years, their friendship deepened, and she came to believe it might grow into something more. Twice she proposed marriage, but Eliot always led her to understand that any such commitment would be impossible for him. Then the revelation of his long attachment to Emily Hale-and the sudden shock of his marriage to his secretary, Valerie Fletcher-caused a rupture between Trevelyan and the poet that could not be overcome.

Mary Trevelyan left a unique chronicle- including diaries, letters, and pictures-that charts their twenty-year relationship. Now Erica Wagner has given it shape and context, bringing this untold story to light for the first time. Mary and Mr. Eliot is a tale of joy, misunderstanding, and betrayal that feels utterly modern and deeply human.
