The name Saki is often thought to be a reference to the cupbearer in the Rubáiyát of Omar Khayyam, a poem mentioned disparagingly by the eponymous character in "Reginald on Christmas Presents" and alluded to in a few other stories. (This is stated as fact by Emlyn Williams in his 1978 introduction to a Saki anthology) It may, however, be a reference to the South American primate of the same name, "a small, long-tailed monkey from the Western Hemisphere" that is a central character in "The Remoulding of Groby Lington"

Hector Hugh Munro was born in Akyab, Burma (now known as Sittwe), the son of Charles Augustus Munro and Mary Frances Mercer. His father was an inspector-general for the Burmese police when that country was still part of the British Empire. In 1872, his mother, who had gone home on a visit to England, was charged by a cow; the shock caused her to miscarry. She never recovered and soon died AJLangguth.com - "Saki: A Life of Hector Hugh Munro, with six short stories never before collected." (Hamish Hamilton, London, 1981). Charles Munro sent his children, including two-year-old Saki, to England, where they were brought up by their grandmother and aunts in a strict, straitlaced household.

Munro was educated at Pencarwick School in Exmouth and at Bedford Grammar School. When his father retired to England, he travelled on a few occasions with his sister and father, between fashionable European spas and tourist resorts. In 1893, he followed in his father's footsteps by joining the Indian Imperial Police, where he was posted to Burma (as was another acerbic and pseudonymous writer a generation later: George Orwell). Two years later, failing health from malaria forced his resignation and return to England, where he started his career as a journalist, writing for newspapers such as the Westminster Gazette, Daily Express, Bystander, Morning Post, and Outlook.

In 1900, Munro's first book appeared: The Rise of the Russian Empire, a historical study modelled upon Edward Gibbon's magnum opus The Decline and Fall of the Roman Empire.

From 1902 to 1908, Munro worked as a foreign correspondent for The Morning Post in the Balkans, Warsaw, Russia (where he witnessed Bloody Sunday), and Paris; he then gave that up and settled in London. Many of the stories from this period feature the elegant and effete Reginald and Clovis, young men-about-town who take heartlessly cruel delight in the discomfort or downfall of their conventional, pretentious elders. In addition to his well-known short stories, Saki also turned his talents for fiction into novels. Shortly before the Great War, with the genre of invasion literature selling well, he published a "what-if" novel, When William Came, subtitled "A Story of London Under the Hohenzollerns", imagining the eponymous German emperor conquering Britain.

At the start of World War I, although 43 and officially over age, Munro joined the Royal Fusiliers regiment of the British Army as an ordinary soldier, refusing a commission. More than once he returned to the battlefield when officially still too sick or injured to fight. He was sheltering in a shell crater near Beaumont-Hamel, France in November 1916 when he was killed by a German sniper. His last words, according to several sources, were "Put that bloody cigarette out!" After his death, his sister Ethel destroyed most of his papers and wrote her own account of their childhood.

Munro never married. His biographer A. J. Langguth cites evidence for the hypothesis that Munro was homosexual. At that time in the UK sexual activity between men was a crime, and the Cleveland Street scandal in 1889, followed by the downfall and disgrace of Oscar Wilde (who was convicted in 1895 after cause celebre trials) meant that "that side of [Munro's] life had to be secret". Politically, Munro was a Tory and somewhat reactionary in his views.

In recognition of his contribution to literature, a blue plaque has been affixed to a building in which Munro once lived on Mortimer Street in central London.

Saki's world contrasts the effete conventions and hypocrisies of Edwardian England with the ruthless but straightforward life-and-death struggles of nature. Nature generally wins in the end.

Saki's work is now in the public domain, and all or most of these stories are on the Internet.

Some of his best-known short stories are listed below.

"The Interlopers"

"The Interlopers" is a story based on two men, Georg Znaeym and Ulrich von Gradwitz, whose families have fought over a forest in the eastern Carpathian Mountains for generations. Ulrich's family legally owns the land, but Georg — feeling it rightfully belongs to him — hunts there anyway. One winter night, Ulrich catches Georg hunting in his forest. The two would never shoot without warning and soil their family’s honour, so they hesitate to acknowledge one another. As an “act of God,” a tree branch suddenly falls on each of them, trapping them both under a log. Gradually, they realize the futility of their quarrel and become friends to end the family feud. They call out for their men’s assistance, and after a brief period, Ulrich makes out ten figures approaching over a hill. The story ends with Ulrich’s realization that the "interlopers" on the hill are actually wolves.

"The Schartz-Metterklume Method"

At a railway station, an arrogant and overbearing woman mistakes the mischievous Lady Carlotta for the governess she expected. Lady Carlotta, deciding not to correct the mistake, presents herself as a proponent of "the Schartz-Metterklume method" of making children understand history by acting it out themselves, and chooses a rather unsuitable historical episode for her first lesson.

"The Toys of Peace"

Rather than giving her young boys gifts of toy soldiers and guns, their mother instructs her brother to give the children "peace toys" as an Easter present. When the packages are opened, young Bertie shouts "It's a fort!" and is disappointed when his uncle replies "It's a municipal dust-bin". The boys are initially baffled as to how to obtain any enjoyment from models of a school of art and a public library, or from little toy figures of John Stuart Mill, poetess Felicia Hemans, and astronomer Sir John Herschel. Youthful inventiveness finds a way, however.

"The Storyteller"

"The Storyteller" is a cynical antidote to crude didacticism. An aunt is traveling by train with her two nieces and a nephew. The children are naughty and mischievous. A bachelor is sitting opposite. The aunt starts telling a moralistic story, but is unable to satisfy the curiosity of the children. The bachelor intervenes and tells a story where the "good" person ends up being unwittingly devoured by a wolf, much to the children's delight. The bachelor is amused with the knowledge that in the future the children will embarrass their guardian by begging to be told "an improper story".

"The Unrest-Cure"

Saki's recurring hero Clovis Sangrail, a sly young man, overhears the complacent middle-aged Huddle complaining of his own addiction to routine and aversion to change. Huddle's friend makes the wry suggestion of the need for an "unrest-cure" (the opposite of a rest cure) to be performed, if possible, in the home. Clovis takes it upon himself to "help" the man and his sister by involving them in an invented outrage that will be a "blot on the twentieth century".

"Esmé"

In a hunting story with a difference, the Baroness tells Clovis of a hyena she and her friend Constance encountered alone in the countryside, who cannot resist the urge to stop for a snack. The story is a perfect example of Saki's delight in setting societal convention against uncompromising nature.

The wailing accompaniment was explained. The gypsy child was firmly, and I expect painfully, held in his jaws.

The child is shortly devoured.

Constance shuddered. "Do you think the poor little thing suffered much?" came another of her futile questions.

"The indications were all that way,' I said; 'on the other hand, of course, it may have been crying from sheer temper. Children sometimes do."

"The Open Window"

A man with the unlikely name of Framton Nuttel comes to a country village for some peace and rest. He calls upon a lady named Mrs. Sappleton his sister used to know; for a few minutes he is left alone with her niece named Vera, who has quite an active imagination. She tells Framton a story about the tragedy of the lady's husband and two younger brothers, who had gone hunting one day three years earlier and never returned. The bodies were never found, and because of this the window from which they left is always kept open. When indeed they do return that very night, Framton, who has suffered from nerves in the past, runs out of the house, and the niece explains his sudden departure to her relatives with an equally imaginative fiction.

"Sredni Vashtar"

The story of a young, sickly child, Conradin. His cousin and guardian, Mrs. De Ropp, "would never... have confessed to herself that she disliked Conradin, though she might have been dimly aware that thwarting him 'for his good' was a duty which she did not find particularly irksome."

"Tobermory"

At a country house party a visiting professor announces to the guests that he has perfected a procedure to teach animals human speech. He demonstrates this on his host's cat, Tobermory. Soon it is clear that animals are permitted to view many private things on the assumption that they will remain silent...

"The East Wing"

A 're-discovered' short story, previously cited as a play and therefore less well known. A house party with its typical social mix of bumbling Major Boventry, the precious Lucien Wattleskeat, the wordy Canon Clore and a breathless hostess, Mrs Gramplain, is beset by a fire in the middle of the night in the east wing of the house. Begged by their hostess to save "my poor darling Eva — Eva of the golden hair," Lucien demurs on the grounds that he has never even met her. It is only on discovering that Eva is not a flesh and blood daughter, but Mrs Gramplain's painting of the daughter that she wished that she had had and which she has faithfully updated with the passing years, that Lucien declares a willingness to forfeit his life to rescue her, since "death in this case is more beautiful," a sentiment endorsed by the Major. As the two men disappear into the blaze, Mrs Gramplain recollects that she "sent Eva to Exeter to be cleaned." Thus the two men have lost their lives for nothing.
