 Born in the British Embassy in Paris, where his father worked, Maugham was an orphan by the age of ten.
 He was raised by an uncle, who tried to persuade the youngster to become an accountant or parson; Maugham instead trained as a doctor, although he never practised professionally, as his first novel, "Liza of Lambeth", was published the same year he qualified.

 The award is to be spent on foreign travel.

 He was also the literary prototype of the spymaster of a number of Somerset Maugham's short stories.
 Wallinger is credited with leading the Indian intelligence missions outside India, notably against the Indian Anarchist movement in England, and later against the Berlin Committee and the Hindu-German Conspiracy during World War I.
 Among his more famous agents was Somerset Maugham, whom he recruited in London and sent as a secret agent to Switzerland.

 Published in 1945 by the Vanguard Press, it was the first of L'Engle's long list of books, and was reprinted in 1984.

Somerset Maugham", a biography based on extensive archival work and interviews with surviving associates of Maugham, in particular Alan Searle.
 Unlike Ted Morgan, who had obtained permission from Maugham's executors to publish from Maugham's letters in his biography (1980), Calder was refused permission to do so by the Royal Literary Fund and had to rely on paraphrase in referencing Maugham's unpublished correspondence.
