Everyone knows that the world is flat and supported on the backs of four elephants. But weren't there supposed to be five? Indeed there were. So where is it?
When duty calls, Commander Vimes of the Ankh-Morpork constabulary answers—even if he doesn't want to. Now, he's been invited to attend a royal function as both detective and diplomat. The one role he relishes; the other requires, well, ruby tights. Of course, where cops (even those clad in tights) go, alas, crime follows. An attempted assassination and a theft soon lead to a desperate chase from the low halls of Discworld royalty to the legendary fat mines of Uberwald, where lard is found in underground seams along with tusks and teeth and other precious ivory artifacts. It's up to the dauntless Vimes—bothered as usual by a familiar cast of Discworld inhabitants (you know, trolls, dwarfs, werewolves, vampires, and such)—to solve the puzzle of the missing pachyderm. Which, of course, he will . . . after all, solving mysteries is his job.
Pratchett is always at his best when the comedy is combined with a real sense of jeopardy that even favorite characters might be hurt if there was a good joke in it. As always, the most unlikely things crop up as the subjects of gags--Chekhov, grand opera, the Caine Mutiny--and as always there are remorselessly funny gags about the inevitability of story:
They say that the fifth elephant came screaming and trumpeting through the atmosphere of the young world all those years ago and landed hard enough to split continents and raise mountains.
No one actually saw it land, which raised the interesting philosophical question: when millions of tons of angry elephant come spinning through the sky, and there is no one to hear it, does it--philosophically speaking--make a noise?
As for the dwarfs, whose legend it is, and who mine a lot deeper than other people, they say that there is a grain of truth in it.
