If the Shire is a suburban garden, Sauron and his henchmen are that old bourgeois bugaboo, the Mob - mindless football supporters throwing their beer-bottles over the fence - the worst aspects of modern urban society represented as the whole by a fearful, backward-yearning class for whom "good taste" is synonymous with "restraint" (pastel colours, murmured protest) and "civilized" behaviour means "conventional behaviour in all circumstances".

Next time you pick up a Heinlein book think of the author as looking a bit like General Eisenhower or, if that image isn't immediate enough, some chap in early middleage, good-looking in a slightly soft way, with silver at the temples, a blue tie, a sober three-pieced suit, telling you with a quiet smile that Margaret Thatcher cares for individualism and opportunity above all things, as passionately in her way as you do in yours. And then you might have some idea of what you're actually about to read.
