Rumer Godden: The Lady and the Unicorn

"Stephen had not thought that winter would be beautiful in India. He had had a revulsion from the country, all its romance had turned to sordidness, but now the land filled him again with delight. He was thinking of Rosa. "Promise me," she had whispered, "promisme me you won't go back without me." Mystery pervades this story of Anglo-Indian lifle in a memory-haunted house in old Calcutta, as secret as a sundial in a ruined garden."--Goodreads.com
