Who would not wish to be the man in charge of Ankh-Morpork's Royal Mint and the bank next door? It's a job for life. But, as former conman Moist von Lipwig is learning, life is not necessarily for long.
The Chief Cashier is almost certainly a vampire. There's something nameless in the cellar (and the cellar itself is pretty nameless), and it turns out that the Royal Mint runs at a loss. A three-hundred-year-old wizard is after his girlfriend, he's about to be exposed as a fraud, but the Assassins' Guild might get him first. In fact, a lot of people want him dead.
Oh. And every day he has to take the Chairman for walkies.
Everwhere he looks he's making enemies. What he should be doing is... making money!
