I tried reading this book years ago. Unfortunately, at that time, I was...unfamiliar with Discworld. I didn't get past the first chapter. So, having read...several...and now being familiar with Vetinari, among others, I decided to give it another go.
While my favorite characters are still Rincewind and Vimes, Moist is...interesting. I found myself wondering if the Patrician expected him to succeed, or was merely entertaining himself. One never knows with him. His mind games leave you constantly guessing.
So Moist, having been caught and condemned for being a perpetual con artist, is hanged, and offered a job. Not like he has a whole lot of options. So of course the post office sucks him in and challenges him to make it work. And of course, mayhem occurs along the way.
