In 1938 T.S. Eliot struck up a friendship with Mary Trevelyan, a passionately curious woman and intrepid traveller. Their relationship was cosy and domestic - characterised by churchgoing, record-playing, day trips with Mary at the wheel or Eliot in his rolled shirt-sleeves cooking up sausages for dinner. Over the years, Mary came to believe that their friendship might lead to something more ... but their journey together did not end as she would have hoped. Trevelyan left a unique document - of diaries, letters and pictures - charting their twenty-year-long relationship in her vivid prose. Erica Wagner has brought this untold story together for the first time. Mary and Mr Eliot is a revelatory tale of joy, misunderstanding and betrayal that feels utterly modern and deeply human.
