The "William" of the book's title is Kaiser Wilhelm II, who came from the House of Hohenzollern, hence the subtitle. The book chronicles life in London under German occupation and the changes that come with a foreign army's invasion and triumph. What we find frightening about this novel is the very premise: England has been subjugated and annexed by Germany . . . When William Came, written before World War I, is a grim tale of a then-fictional war between Britain and Germany. Saki's biting wit is aimed squarely at British politics in this thinly veiled story -- he, like many others, could see war approaching, and who would want to see a conflict of such proportion? Unnerving stuff, we say. . . .
