Based on situation rather than story

"I lean more heavily on intuition, and have been able to do that because my books tend to be based on situation rather than story. Some of the ideas which have produced those books are more complex than others, but the majority start out with the stark simplicity of a department store window display or a waxwork tableau. I want to put a group of characters (perhaps a pair; perhaps even just one) in some sort of predicament and then watch them try to work themselves free. My job isn't to help them work their way free, or manipulate them to safety - those are jobs which require the noisy jackhammer of plot - but to watch what happens and then write it down." (#2 p.160-161)

The most interesting situations can usually be expressed as a What-if question

"A strong enough situation renders the whole question of plot moot, which is fine with me. The most interesting situations can usually be expressed as a What-if question: What if vampires invaded a small New England village? (Salem's Lot)." (#2 p.166)
