Angela Margaret Thirkell (née Mackail, 30 January 1890 – 29 January 1961) was an English and Australian novelist. She also published one novel, Trooper to Southern Cross, under the pseudonym Leslie Parker.
She was the elder daughter of John William Mackail, a Scottish classical scholar and civil servant from the Isle of Bute who was the Oxford Professor of Poetry from 1906 to 1911. Her mother was Margaret Burne-Jones, daughter of the Pre-Raphaelite painter Edward Burne-Jones, and through her, Thirkell was the first cousin once removed of Rudyard Kipling and Stanley Baldwin.
She was married and divorced twice. Thereafter, her “attitude to any man to whom she attracted was summed up in the remark: ‘It’s very peaceful with no husbands.'”
She needed to earn a living so she set forth on the difficult road of the professional writer. Her first book, Three Houses, a memoir of her happy childhood was published in 1931 and was an immediate success. The first of her novels set in Trollope’s mythical county of Barsetshire was Demon in the House, followed by 28 others, one each year.
