When William Came: A Story of London Under the Hohenzollerns is a novel written by the British author Saki (the pseudonym of Hector Hugh Munro) and published in November 1913.
[3] The "William" of the book's title is German Emperor Kaiser Wilhelm II of the House of Hohenzollern.
The book chronicles life in London under German occupation and the changes that come with a foreign army's invasion and triumph.
The scene in which an Imperial Rescript is announced in a subjugated London, excusing the unmilitary British from serving in the Kaiser's armies, is particularly bitter.
There are also several vignettes exemplifying the differences between the English and continental systems of law – Yeovil's wife informs him that she must register his presence with the police and later he is fined on the spot for walking on the grass in Hyde Park.
