I think I may have stared at her, just to occupy my thoughts. She cocked her head and smiled at me and said hello. Her voice startled me and I experienced that quick intestinal collapse you sometimes get in bed when you think you are falling. I made a brisk British military nod (that month’s mask, picked up in the psychological warehouse that stored other people’s discarded personalities) and I thought: I’m getting the timing screwed up. My life would have had to be a movie for the plan to really work the way I wanted—I wanted to time my passing the Butterfields’ house just as they were coming out. But I felt there was some split-second urgency involved and so I quickly started out toward the house, first at a trot and then at a dead run.

Was I running for the sake of my masterplan or did I somehow know that the fire I’d set had leapt out of control? Did I smell smoke or did the part of me that had understood from the beginning the consequence of my actions finally fight its way through the thicket of wilfulness and heartsickness to scream its alarm? I ran and now my heart was not beating with a lover’s mournful nervousness but it seemed to bound against my chest like a furious dog against a fence.

I don’t understand how fire works; I haven’t learned the scientific explanations for its cunning and greed. A lick of flame can scurry like a cat while it hunts for the choicest morsel of fuel. An infant flame is subject to the government of the elements. But by adolescence, fire is as brave and artful as a revolutionary band, snatching easy victories here, extending the limits of its power there, consolidating, attacking, brightening with triumph. At its full force, its victory over the stable world complete and everything from Doric columns to magazine racks within its mercy, fire is messianic—it rules over its domain with a blistering, totalitarian authority and seems to believe that all of creation ought be in flames.
