El confín del mundo (The Witcher de Andrzej Sapkowski: el último deseo, 3)

Geralt struggles to find work… and Jaskier, to find material for his rhymes or ballads. When they travel to the edge of the known world, the locals tell them many stories, but they seem to be just that: fables about monsters and superstitions. Until a man follows Geralt with news of a devil lurking in the fields. They wish him to rid them of the beast, but under no circumstances must he kill it. However, how can he possibly hunt the creature, when devils don't exist?
