From  KatherineMansfield.com:

Katherine Mansfield was a world-renowned short story writer and New Zealand's most famous author. Three volumes of her stories appeared in her lifetime (1988-1923). ... In addition to her stories, the letters and journals published by her husband, John Middleton Murry, reveal intimate details of her life and thoughts. He also published private papers, as well as unfinished stories and poems.

In London in 1911, Mansfield met John Middleton Murry, an Oxford scholar, prominent critic, and editor of a literary quarterly publication, Rhythm. They became lovers and were later to marry in 1918.

Mansfied and Murry were closely associated with D.H. Lawrence and his wife Frieda. They shared a house in England in 1914-15.  Lawrence's novel, Women in Love, has characters that are probably partially based on Lawrence and his wife, and Murry and Mansfield.
