The Jesuit Father Martin D'Arcy (1888–1976) was eminent both as a theologian and an aesthete. As Master of Campion Hall, Oxford, he rebuilt the house to a design by Lutyens, while his converts included Evelyn Waugh, Lord Longford and Edith Sitwell. This biography investigates his career and beliefs; his tragic friendship with Henry John, son of the painter Augustus; and his abrupt dismissal as Superior of the English Jesuit Province.
