 I want to explore the slasher from every angle I can. And with I Was a Teenage Slasher, I found what feels like a new doorway into the slasher. And that's through the slasher's head, through his eyes, through his voice, through his memory. And I want to understand this genre as well as I can. And so in order to do that, I have to come at it from all angles. And coming at it from the killer's angle seems like a step I should have taken five or six books ago already.
