A Partridge in a Pear Tree by Rachel Rodman
This is horror in its truest sense--not some gore soaked slasher story or pseudo-psychotic self-referential dream-scape.
No, this is the baby at the moment she falls over the railing.
It's the kind of story that you read and you see it unfolding on the page and you know it's all going tragically wrong and you simply can't stop because it's such a beautifully composed piece of literature that simply watching the mechanism working flawlessly from end to end is worth the pain of watching it self destruct as you keep devouring word after word. This is the kind of story that you realize is only one step to the left from where you are right now, far enough away that you can wave it off as pure fiction but close enough that a single "what if" means it's real. It's the kind of story that keeps you up at night, not because of the monster in the closet or under the bed, but because of the monster inside you.
