Where Stands A Winged Sentry, taken from the author's war diaries, conveys the tension, frustration and bewilderment of the progression of the Second World War, and the terror of knowing that the worst is to come, but not yet knowing what the worst will be.

Margaret Kennedy was a novelist and playwright, most famous for her second novel The Constant Nymph (1924). She was born in London on 23 April 1896, the eldest of four children, and holidayed with her family in Cornwall for years. Margaret read history at Somerville College, Oxford. Her brother Tristram was killed in 1918 fighting near Jerusalem.
Margaret graduated with the equivalent of a second-class degree in history in 1919 (the year before women were allowed to take their degrees at Oxford). In 1923 her first novel was published, The Ladies of Lyndon, which received little attention. While she was working on this book she had gone to Pertisau on Achensee in the Austrian Tyrol to stay with friends, and discovered a passion for mountains and walking. It also gave her a setting for her next novel, The Constant Nymph, and she returned to Pertisau to finish the novel.
The Constant Nymph was widely acclaimed, and Margaret received congratulations from the leading literary figures of the day, including Thomas Hardy, George Moore, A E Housman and Arnold Bennett. She married in 1925, and had three children. In the late 1920s the family bought Hendre Hall, a large house in Llwyngwril near Barmouth on the North Wales coast, which was their holiday home for many years.
In 1937 David Davies became a County Court judge, while Margaret had become a leading literary figure. With the approach of war Margaret's health began to deteriorate due to emotional stress. By the middle of 1940 the family had left Hendre Hall for a brief stay in Surrey, and then Margaret and the children moved to St Ives with Nanny, while David remained in London. Margaret visited London frequently for committees and to see her husband, and eventually moved her children and Nanny out of their rented home into a hotel, which made her housekeeping much easier. In 1943 she and the children and Nanny left Cornwall, for James to go to prep school and the girls to go to Oxford High School. In July 1944 their London house was completely destroyed by a VI flying bomb. They moved into a new home a few streets away, at 11 Argyll Road, where the family stayed for fourteen years.
In 1947 Margaret visited the USA for the first time, and began writing a new cycle of novels, and an acclaimed biography of Jane Austen. More critical writing followed, accompanied by increasing deafness. David Davies was knighted in 1952. His death in 1964 was a great blow to Margaret. Her health continued to deteriorate, and she died in 1967 aged seventy-one.
