We all go a little mad sometimes

These are books that read like a slasher flick. They usually follow 'the rules'- from the killer being unknown and seemingly invincible, to the final girl survivor. But not all are so cut and dried. So enjoy, gentle reader, what you can of them. Although if you find these books enjoyable, God help us. Unlike most of my other lists I'm not trying to bring lesser known works to light but to tag an idea wherever it might fester, so some of these books may be familiar to you.
