““He'd taken the sword, slung on his back, sandwiches and clean underwear in his pack, and the world, more or less, at his feet. In his pocket was the famous letter from the Patrician, the man who ruled the great fine city of Ankh-Morpork. At least, that's how his mother had referred to it. It certainly had an important-looking crest at the top, but the signature was something like "Lupin Squiggle, Sec'y, pp". Still, if it wasn't actually signed by the Patrician then it had certainly been written by someone who worked for him. Or in the same building. Probably the Patrician had at least known about the letter. In general terms. Not this letter, perhaps, but probably he knew about the existence of letters in general.””
