The Peepstone Problem
Unreliable narrators pose a problem for the stories they tell. They make the world they depict for us, and we see that world through their eyes. In fiction, unreliable narrators betray themselves in a variety of ways or, to be more precise about it, they are betrayed by the writers who invented them. Unreliable narrators can be deceptive, but readers nevertheless slowly begin to doubt the narrator when contrary facts are revealed.
