Although a student of fine art, D'Arcy abandoned this career, allegedly on the grounds of poor eyesight, in favour of becoming an author.
[2] Living in London, and working as a contributor to, and unofficial editor of, alongside Henry Harland, the Yellow Book, D'Arcy's work is characterised by a psychologically realist style – often attracting comparisons with Henry James – and her determination to engage with themes such as marriage, the family, deception and imitation.
[2] As well as writing fiction, D'Arcy also translated into English André Maurois's biography of Percy Bysshe Shelley, Ariel (1924).
D'Arcy was notorious for her inability to maintain contact with her friends, exacerbated by her love of travel, often appearing unannounced, earning her the nickname 'Goblin Ella.
Her writing, although demonstrating a real engagement with the changing and challenging artistic styles of the late nineteenth century, was motivated by need.
