* * * * * _Somewhere in Christendom_ (ALLEN AND UNWIN) is somewhat embarrassing to a reviewer, for it has the theme of a great book with the manner of a trivial one. It is the history of a very much smaller nation, Ethuria, left despoiled and starving at the end of a nine-years' war, in which its great neighbours have used it as a battle-ground. Revolution begins, but a woman prophet steps in and switches it off in an unusual direction. The Ethurians perfect among themselves that fellowship which is the nice ideal behind many nasty manifestations in the real world, and, when next they are invaded by neighbouring nations anxious to use them as an excuse for belligerency, they resolutely stick to their guns (only the metaphor is most unsuitable), refuse to find any cause of quarrel with their "foreign brothers," and finally persuade them to abandon the ideals of war, so that peace on earth becomes a reality at last. Here is the book's theme; its working out allows for a boxing match between the President of Hygeia and the Foreign Secretary of Tritonia as the minimum of hostilities; a wicked newspaper lord, who pulls strings in both countries, and a faithful butler to the Royal Family, who becomes assistant state nursemaid and cleans silver as a hobby. Though I quite agree with Miss EVELYN SHARP and the Ethurians that it _is_ love that makes the world go round, I am not so sure that either hers or theirs is the best way of advocating their common cause. * * * * *
