The Colour of Magic

Ankh-Morpork is a city surrounded by darkness, where the cold river Ankh flows, where it always rains, and where dwarves and trolls co-exist with secret societies, religious fanatics, stupid police captains, and bar pianists. It is also where a bitterly sarcastic sharp-eyed private investigator named Lewton tries to earn a living solving bizarre cases. A mysterious woman named Carlotta hires him to find her lost lover. Wandering through the dark city and gathering evidence, Lewton has to solve the case, confront a sinister conspiracy, and once again become torn between love and despair.

You were recently acquired by the brave Ser Leonhart and his squire to sniff out the evil shapeshifting wizard. Unfortunately, you are not a wizard sniffer (if such a thing even exists). As far as you can tell, you are an ordinary pig.

You stagger up to its lair. Blue sand drags at your feet. Your hands don't tremble — well, much — as you ready your new weapon. Your voice doesn't quaver (hardly at all) as you shout out the words you were taught. One, two! Dive and roll! Jump! Attack! ...That wasn't so hard, was it? You defeated the monster, and it's not even bedtime yet. A work of interactive fiction by Andrew Plotkin.

Adaption of the Fighting Fantasy gamebook of the same name.
