In "The Mystery," finished in 1951 but never before published, H.D. tells a tale of love, intrigue, and religious redemption. Drawn from her notes to her memoir, "The Gift," the novel imaginatively re-creates the history of her mother's Moravian Church, Unitas Fratrum, and its leader, Count Zinzendorf, from which she believed she had inherited a psychic "gift." This "gift" enables her to reenvision her inheritance. The Moravian cousins, Elizabeth de Watteville and Henry Dohna, Zinzendorf's grandchildren, travel to Prague in winter 1788, on the eve of the French Revolution. There they meet Count Louis Saint-Germain, a magician and counterrevolutionary plotter, whose life changes as he joins their search to find Zinzendorf's lost Plan for "world unity without war." A hybrid novel combining modernist stream-of-consciousness and medieval legend, "The Mystery" completes H.D.'s cycle of romances following "The Sword Went Out to Sea" and "White Rose and the Red." It reveals her feminist theology and writes finis to her obsession with spiritualism. Jane Augustine's introduction and extensive notes provide a significantly enlarged view of H.D.'s religious thinking. H.D., well-known as an Imagist poet, has reemerged as a major modernist writer through publication of her previously unavailable prose. Jane Augustine, an independent scholar, has written four books of poetry and numerous essays on women writers, gender, and religion. She also edited "The Gift by H.D.: The Complete Text."
