Technically, the city of Ankh-Morpork is a Tyranny, which is not always the same thing as a monarchy, and in fact even the post of Tyrant has been somewhat redefined by the incumbent, Lord Vetinari, as the only form of democracy that works. Everyone is entitled to vote, unless disqualified by reason of age or not being Lord Vetinari. And yet it does work. This has annoyed a number of people who feel, somehow, that it should not, and who want a monarch instead, thus replacing a man who has achieved his position by cunning, a deep understanding of the realities of the human psyche, breathtaking diplomacy, a certain prowess with the stiletto dagger, and, all agree, a mind like a finely balanced circular saw, with a man who has got there by being born.† However, the crown has hung on anyway, as crowns do–on the Post Office and the Royal Bank and the Mint and, not least, in the sprawling, brawling, squalling consciousness of the city itself. Lots of things live in that darkness. There are all kinds of darkness, and all kinds of things can be found in them, imprisoned, banished, lost or hidden. Sometimes they escape. Sometimes they simply fall out. Sometimes they just can’t take it any more.
