Listen, I've always been a situational writer. My idea of what to do with a plot is to shoot it before it can breed. It's true that when I start a story, I usually have a general idea of where it's going to finish up, but in many cases I end up in a different place entirely (for instance, I fully expected Ben Mears to die at the end of 'Salem's Lot, and Susannah Dean was supposed to pop off at the end of Song of Susannah). "The book is the boss," Alfred Bester used to say, and what that means to me is the situation is the boss. If you play fair with the characters—and let them play their parts according to their strengths and weaknesses—you can never go wrong. It's impossible.
