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) What if a policeman in a remote Nevada town went berserk and started killing everyone in sight? (Desperation) What if a cleaning woman suspected of a murder she got away with (her husband) fell under suspicion for a murder she did not commit (her employer)? (Dolores Claiborne)
