D. Wallace 
Sisters and Rivals in British Women”s Fiction, 1914-39 [PDF ebook] 

What happens when two women love the same man? This is the first book to examine female rivalry as a distinctive theme in women”s fiction and to analyze the female-identified erotic triangle, where two women are rivals for the same man, as a narrative pattern which has a special resonance for inter-war women writers. Focusing on five key writers, Diana Wallace offers a reconsideration of inter-war women”s writing and an examination of the links and rivalries between women writers themselves.
