Jane Oliver

"In her fascinating introduction to Business as Usual, the publisher Kate Macdonald details the writing careers of two remarkable women authors – Helen Rees (1903–70) and Anne Pedlar (1900–66) – who, under the pseudonyms Jane Oliver and Ann Stafford, produced a staggering ninety-seven novels, both individually and together. And yet who has heard of them today? Jane Oliver in particular was best known for her meticulously researched historical novels, the royalties from which enabled her to set up the prestigious John Llewellyn Rhys literary prize in 1942 in memory of her husband, which ran for almost seventy years until its demise in 2010." https://web.archive.org/web/20201126131205/https://www.the-tls.co.uk/articles/business-as-usual-jane-oliver-ann-stafford-review-gerri-kimber/
