Discworld: Moist von Lipwig

Moist von Lipwig is a con artist and a fraud and a man faced with a life choice: be hanged, or put the ailing postal service of Ankh-Morpork back on its feet. It's a tough decision. The post is a creaking old institution, overshadowed by new technology. But there are people who still believe in it and Moist must become one of them if he's going to see that the mail gets through, come rain, hail, sleet, dogs, the Post Office Workers Friendly and Benevolent Society, an evil chairman...and a midnight killer. Getting a date with Adora Bell Dearheart would be nice, too.

The Royal Bank is facing a crisis, and it's time for a change of management. There are a few problems that may arise with the job.... The Chief Cashier is almost certainly a vampire - there's something nameless in the cellar and it turns out that the Royal Mint runs at a loss. Meanwhile, people actually want to know where the money's gone. It's a job for life. But, as former con-man Moist von Lipwig is learning, that life is not necessarily a long one. He's about to be exposed as a fraud, but if he's lucky the Assassins' Guild might get him first. 

Change is in the air for Moist von Lipwig, swindler, con-man and (naturally) head of the Royal Bank and Post Office. A steaming, clanging new invention - a steam locomotive named Iron Girder, to be precise - is drawing astonished crowds. Suddenly it's a matter of national importance that the trains run on time. Moist does not enjoy hard work. His input at the bank and post office consists mainly of words, which are not that heavy. Or greasy. And it certainly doesn't involve rickety bridges, runaway cheeses or a fat controller with knuckledusters.
