Dame Ngaio Marsh, born Edith Ngaio Marsh, was a New Zealand crime writer and theatre director. There is some uncertainty over her birth date as her father neglected to register her birth until 1900, but she was born in the city of Christchurch, New Zealand. Of all the "Great Ladies" of the English mystery's golden age, including Margery Allingham, Agatha Christie, and Dorothy L. Sayers, Ngaio Marsh alone survived to publish in the 1980s. Over a fifty-year span, from 1932 to 1982, Marsh wrote thirty-two classic English detective novels, which gained international acclaim. She did not always see herself as a writer, but first planned a career as a painter. Marsh's first novel, A MAN LAY DEAD (1934), which she wrote in London in 1931-32, introduced the detective Inspector Roderick Alleyn: a combination of Sayers' Lord Peter Wimsey and a realistically depicted police official at work. Throughout the 1930s Marsh painted occasionally, wrote plays for local repertory societies in New Zealand, and published detective novels. In 1937 Marsh went to England for a period. Before going back to her home country, she spent six months travelling about Europe. All her novels feature British CID detective Roderick Alleyn. Several novels feature Marsh's other loves, the theatre and painting. A number are set around theatrical productions (Enter a Murderer, Vintage Murder, Overture to Death, Opening Night, Death at the Dolphin, and Light Thickens), and two others are about actors off stage (Final Curtain and False Scent). Her short story "'I Can Find My Way Out" is also set around a theatrical production and is the earlier "Jupiter case" referred to in Opening Night. Alleyn marries a painter, Agatha Troy, whom he meets during an investigation (Artists in Crime), and who features in several later novels. Series: * Roderick Alleyn

Philip MacDonald (who some give as 1896 or 1899 as his date of birth) was the grandson of the writer George MacDonald and son of the author Ronald MacDonald and the actress Constance Robertson. During World War I he served with the British cavalry in Mesopotamia, later trained horses for the army, and was a show jumper. He also raised Great Danes. After marrying the writer F. Ruth Howard, he moved to Hollywood in 1931. He was one of the most popular mystery writers of the 1930s, and between 1931 and 1963 wrote many screenplays along with a few radio and television scripts. His detective novels, particularly those featuring his series detective Anthony Gethryn, are primarily "whodunnits" with the occasional locked room mystery. His first detective novel was 'The Rasp' (1924), in which he introduced his character Anthony Gethryn. In later years MacDonald wrote television scripts for Alfred Hitchcock Presents ('Malice Domestic', 1957) and Perry Mason ('The Case of the Terrified Typist', 1958). He twice received an Edgar Award for Best Short Story: in 1953, for 'Something to Hide', and in 1956, for 'Dream No More'. Indeed many critics felt that his short story writing was superior to his novels and they did win five second prizes in the annual contests held by 'Ellery Queen's Mystery Magazine'. He also wrote under the pseudonyms Oliver Fleming, Anthony Lawless, Martin Porlock, W.J. Stuart and Warren Stuart.

George Douglas Howard Cole was an English political theorist, economist, writer and historian. As a libertarian socialist he was a long-time member of the Fabian Society and an advocate for the cooperative movement. He and his wife Margaret Cole (1893-1980) together wrote many popular detective stories, featuring the investigators Superintendent Wilson, Everard Blatchington and Dr Tancred. Cole was educated at St Paul's School and Balliol College, Oxford. As a conscientious objector during World War One, Cole's involvement in the campaign against conscription introduced him to a co-worker, Margaret Postgate, whom he married in 1918. The couple both worked for the Fabian Society for the next six years before moving to Oxford, where Cole started writing for the Manchester Guardian. During these years, he also authored several economic and historical works including biographies of William Cobbett and Robert Owen. In 1925, he became reader in economics at University College, Oxford. In 1944, Cole became the first Chichele Professor of Social and Political Theory at Oxford. He was succeeded in the chair by Isaiah Berlin in 1957.

Alan Alexander Milne (pronounced /ˈmɪln/) was an English author, best known for his books about the teddy bear Winnie-the-Pooh and for various children's poems. A. A. Milne was born in Kilburn, London, to parents Vince Milne and Sarah Marie Milne (née Heginbotham) and grew up at Henley House School, 6/7 Mortimer Road (now Crescent), Kilburn, a small public school run by his father. One of his teachers was H. G. Wells who taught there in 1889–90. Milne attended Westminster School and Trinity College, Cambridge, where he studied on a mathematics scholarship. While there, he edited and wrote for Granta, a student magazine. He collaborated with his brother Kenneth and their articles appeared over the initials AKM. Milne's work came to the attention of the leading British humour magazine Punch, where Milne was to become a contributor and later an assistant editor. Milne joined the British Army in World War I and served as an officer in the Royal Warwickshire Regiment and later, after a debilitating illness, the Royal Corps of Signals. He was discharged on February 14, 1919. After the war, he wrote a denunciation of war titled Peace with Honour (1934), which he retracted somewhat with 1940's War with Honour. During World War II, Milne was one of the most prominent critics of English writer P. G. Wodehouse, who was captured at his country home in France by the Nazis and imprisoned for a year. Wodehouse made radio broadcasts about his internment, which were broadcast from Berlin. Although the light-hearted broadcasts made fun of the Germans, Milne accused Wodehouse of committing an act of near treason by cooperating with his country's enemy. Wodehouse got some revenge on his former friend by creating fatuous parodies of the Christopher Robin poems in some of his later stories, and claiming that Milne "was probably jealous of all other writers.... But I loved his stuff." He married Dorothy "Daphne" de Sélincourt in 1913, and their only son, Christopher Robin Milne, was born in 1920. In 1925, A. A. Milne bought a country home, Cotchford Farm, in Hartfield, East Sussex. During World War II, A. A. Milne was Captain of the Home Guard in Hartfield & Forest Row, insisting on being plain 'Mr. Milne' to the members of his platoon. He retired to the farm after a stroke and brain surgery in 1952 left him an invalid and by August 1953 "he seemed very old and disenchanted". He was 74 years old when he passed away in 1956.
