I'm currently reading Mo Moulton's THE MUTUAL ADMIRATION SOCIETY: HOW DOROTHY L. SAYERS AND HER OXFORD CIRCLE REMADE THE WORLD FOR WOMEN (Basic, 2019). There's lots of interesting insights into Sayer's life and work plus a good deal of info on life in Oxford and in community theater in England between the wars, health & education of children, developments in women's rights, etc. A thought-provoking book about a group of exceptionally accomplished women.
